AB  - Tooth agenesis is common dentofacial malformation in humans. Its etiology is still not clear. Hypodontia has been regarded as a multifactorial condition influenced by gene function, environmental interaction and developmental timing. More than 300 genes have been related with patterning, morphogenesis and cell differentiation in teeth. According to data WNT10A gene is considered to have an important role in odontogonesis. The aim of this study was to show mutation status in WNT10A gene in a family with two members with diagnosis of hypodontia/oligodontia. In the reported family (father, mother, son, daughter) children were diagnosed with congenital tooth agenesis (son-2 teeth, daughter-11 teeth), while parents negated congenital absence of teeth. We identified a heterozygous missense mutation, c.682T>A (p.Phe228Ile) within the exon 3 of WNT10A in mother and father and the same homozygous mutation was detected in the same region of WNT10A gene in daughter and son. Observed differences in our study, from no symptoms to mild/severe hypodontia, could be the consequence of genetic influence of c.682T>A(p.Phe228Ile) mutation, but also the contribution of many environmental factors during odontogenesis.
AB  - Urođeni nedostatak zuba predstavlja jednu od najčešćih dentofacijalnih anomalija kod čoveka. Etiologija hipodoncije i dalje nije potpuno definisana i smatra se da su za njenu etiologiju odgovorni brojni genetski i sredinski faktori koji deluju u različitim fazama razvoja zuba. Preko 300 gena povezuje se sa morfogenezom i ćelijskom diferencijacijom u toku razvoja zuba, a prema podacima WNT10A gen je jedan od gena koji ima veoma bitnu ulogu u kontroli odontogeneze. Cilj ovog rada bio je da se prikaže mutacioni status WNT10A gena u porodici sa dijagnostikovanom hipodoncijom/oligodoncijom. U prikazanoj porodici (otac, majka, sin i ćerka) kod dva člana dijagnostikovan je urođeni nedostatak zuba (sin - dva zuba, ćerka - 11 zuba), dok kod roditelja ovaj nedostatak nije zabeležen. Kod svih članova porodice, u okviru egzona 3 WNT10A gena detektovana je mutacija c.682T>A (p.Phe228Ile). Kod majke i oca ova 'missense' mutacija je bila u heterozigotnom obliku, dok je kod sina i ćerke utvrđeno prisustvo iste mutacije u homozigotnom obliku. Zabeležene razlike u analiziranoj porodici, od odsustva simptoma do blage hipodoncije i izrazite oligodoncije, mogu biti posledica prisustva c.682T>A (p.Phe228Ile) mutacije, ali takođe i uticaja faktora sredine u toku odontogeneze.

AB  - Introduction/Objective Maxillary or mandibular retrognathism are common dentofacial deformities treated by combined orthodontic-surgical treatment. Surgical maxillary or mandibular advancement changes the position and strain of surrounding structures, which may also affect pharyngeal airway dimensions. The aim of this study was to evaluate and compare three-dimensional pharyngeal airway space changes in patients treated with maxillary advancement and those treated with mandibular advancement. Methods The sample consisted of 25 patients - 12 treated with maxillary advancement and 13 with mandibular advancement surgery. Nasopharyngeal (NP) volume, oropharyngeal (OP) volume, and the area of maximum constriction (AMC) in the OP were measured on cone beam computed tomography scans (2 mA / 120 kV / 12'' FOV) taken before and at least three months after surgery. Paired samples t-test was used for analyzing statistical significance of changes (p ≤ 0.05). Results Postoperative OP and NP volumes, as well as the AMC, increased insignificantly in both groups. Conclusion Results suggest that mono-maxillary surgical advancement of the maxilla or the mandible increases pharyngeal airway dimensions.
AB  - Uvod/Cilj Retrognatizam gornje vilice i retrognatizam donje vilice su česti dentofacijalni deformiteti, koji se leče kombinovanom ortodontsko-hirurškom terapijom. Hirurško pomeranje gornje ili donje vilice unapred menja položaj i napetost okolnih struktura, što takođe utiče na dimenzije faringealnih vazdušnih puteva. Cilj istraživanja bio je da se procene i uporede trodimenzionalne promene faringealnih vazdušnih puteva kod bolesnika lečenih hirurškim pomeranjem gornje ili donje vilice unapred. Metode Uzorak istraživanja se sastojao od 25 bolesnika 12 lečenih hirurškim pomeranjem gornje vilice i 13 lečenih hirurškim pomeranjem donje vilice unapred. Zapremine nazofarinksa i orofarinksa i površine najužeg dela farinksa su merene na CBCT snimcima (2 mA / 120 kV / 12'' FOV) napravljenim pre i bar tri meseca posle hirurške korekcije. Studentov t-test za uparene uzorke je korišćen za analizu statističke značajnosti promena (p ≤ 0,05). Rezultati Zapremine nazofarinksa i orofarinksa i površine najužeg dela farinka povećale su se posle hirurškog pomeranja gornje ili donje vilice unapred. Statistička značajnost nije zabeležena. Zaključak Rezultati ukazuju na to da hirurško pomeranje gornje ili donje vilice unapred dovodi do povećanja dimenzija faringealnih vazdušnih puteva.

AB  - Introduction/Objective Class II malocclusions are sagittal malocclusions characterized by a distal relationship of posterior teeth. Depending on the underlying problem, Class II malocclusions can be skeletal or dentoalveolar. Class II malocclusion treatment modality will depend on the cause, severity, and age. Growth modification is the best treatment option in growing patients with skeletal Class II malocclusions. The aim of this study was to establish and compare sagittal and vertical skeletal and dental changes in patients treated with the 'M block' appliance, the Frankel functional regulator, and the Balters' bionator. Methods The sample consisted of 70 patients diagnosed with skeletal Class II malocclusions (ANB > 4°) and mandibular retrognathism (SNB  lt  80°). The patients were divided into three groups according to the type of appliance. All the patients went through the standard diagnostic procedure (anamnesis, clinical and functional analysis, study model, panoramic radiograph, and cephalometric analysis), and dental and skeletal age was determined. Treatment effects were analyzed on study models and cephalograms at the end of treatment. Results All the appliances led to significant mandibular anterior movement and sagittal growth, which reduced the ANB values. All three groups of patients presented with neutral growth pattern, upper incisor retrusion, and lower incisor protrusion at the end of treatment. Conclusion The results of this study indicate efficacy of all three appliances in skeletal Class II malocclusion treatment.
AB  - Uvod/Cilj rada Malokluzije II klase su sagitalne nepravilnosti zagrižaja koje karakteriše distalni odnos bočnih zuba. U zavisnosti od toga koje strukture su u nepravilnom odnosu, dele se na skeletne i dentoalveolarne. Terapija II klase zavisi od uzroka, izraženosti i uzrasta. Najbolji vid terapije ukoliko pacijenti i dalje rastu je modifikacija rasta. Cilj ove studije bio je da se utvrde i uporede sagitalne i vertikalne promene na skeletnim i dentalnim strukturama u toku lečenja M blok-aparatom, Frenklovim regulatorom funkcije tip I i bionatorom po Baltersu tip I. Metode Sedamdeset ispitanika sa dijagnozom skeletnog distalnog zagrižaja (ANB > 4°) i mandibularnog retrognatizma (SNB  lt  80°), prema vrsti aparata, podeljeni su u tri grupe. Svi su prošli kroz standardnu dijagnostiku (anamneza, klinička i funkcionalna analiza, analiza studijskih modela, ortopantomografskog i profilnog telerendgenskog snimka). Terapijski efekti i promene analizirani su na studijskim modelima i profilnom snimcima po završetku terapije. Rezultati Sva tri aparata dovela su do značajnog mezijalnog usmeravanja i sagitalnog rasta mandibule, što je smanjilo ANB ugao. U sve tri grupe je utvrđen neutralni rast, kao i retruzija gornjih i protruzija donjih sekutića. Zaključak Rezultati studije ukazuju na efikasnost sva tri ispitivana aparata u lečenju skeletnih malokluzija II klase.

AB  - Class III malocclusion is orthodontic anomaly where mandibular arch is in mesial position to maxillary arch. Reasons for Class III malocclusion can be found in mandibular prognathism, maxillar retrognathism or combination of these two. In most cases of mandibular prognathism, it is necessary to postpone the treatment until the growth ceases. However, if certain conditions are accomplished it is possible to start early treatment of class III malocclusion to improve occlusal relations and provide more favorable environment for future growth. The aim of this study was to present treatment of two patients with Class III maloclussion in early mixed dentition, using two different appliances: Delaire mask and Frankel functional regulator type 3. The treatment with Delaire mask resulted in rotation of maxilla downward and forward due to the angle of extraoral part of the mask to the occlusal plane that was modified to be almost 45°. At the end of the treatment facial esthetics was significantly improved. Moving maxilla forward resulted in straight profile, whereas moving maxilla downward lead to coordination of upper, middle and lower facial third. The result of the treatment in patient who used Frankel functional regulator was correction of anterior crossbite by premaxilla development and incisors protrusion. Significant differences in SNA, SNB and ANB angle values at the beginning and at the end of the treatment were not found suggesting that most changes were dental but not skeletal.
AB  - Skeletna malokluzija III klase je nesklad u međusobnom odnosu gornje i donje vilice, jer je donja vilica postavljena mezijalnije u odnosu na gornju. Uzrok nastanka skeletne malokluzije III klase može biti mandibularni prognatizam, maksilarni retrognatizam ili kombinacija ova dva uzroka. U slučaju isuviše razvijene donje vilice najčešće je potrebno sačekati završetak rasta, kako bi se primenilo konačno lečenje. Međutim, ako su ispunjeni određeni uslovi, moguće je primeniti ranu terapiju III klase, da bi se poboljšali okluzalni odnosi i obezbedila dobra osnova za dalji rast. Cilj ovog rada bio je da se prikaže terapijski efekat dva slučaja malokluzije III klase u ranom uzrastu pomoću različitih ortodontskih aparata: Delerove maske i Frenklovog regulatora funkcije tip 3. Kod pacijentkinje koja je tokom lečenja nosila Delerovu masku gornja vilica je zarotirana unapred i nadole, jer je ugao delovanja sile modifikovan da bude skoro 45 stepeni. Na kraju lečenja postignut je znatno bolji izgled lica.

abstract = "Class III malocclusion is orthodontic anomaly where mandibular arch is in mesial position to maxillary arch. Reasons for Class III malocclusion can be found in mandibular prognathism, maxillar retrognathism or combination of these two. In most cases of mandibular prognathism, it is necessary to postpone the treatment until the growth ceases. However, if certain conditions are accomplished it is possible to start early treatment of class III malocclusion to improve occlusal relations and provide more favorable environment for future growth. The aim of this study was to present treatment of two patients with Class III maloclussion in early mixed dentition, using two different appliances: Delaire mask and Frankel functional regulator type 3. The treatment with Delaire mask resulted in rotation of maxilla downward and forward due to the angle of extraoral part of the mask to the occlusal plane that was modified to be almost 45°. At the end of the treatment facial esthetics was significantly improved. Moving maxilla forward resulted in straight profile, whereas moving maxilla downward lead to coordination of upper, middle and lower facial third. The result of the treatment in patient who used Frankel functional regulator was correction of anterior crossbite by premaxilla development and incisors protrusion. Significant differences in SNA, SNB and ANB angle values at the beginning and at the end of the treatment were not found suggesting that most changes were dental but not skeletal., Skeletna malokluzija III klase je nesklad u međusobnom odnosu gornje i donje vilice, jer je donja vilica postavljena mezijalnije u odnosu na gornju. Uzrok nastanka skeletne malokluzije III klase može biti mandibularni prognatizam, maksilarni retrognatizam ili kombinacija ova dva uzroka. U slučaju isuviše razvijene donje vilice najčešće je potrebno sačekati završetak rasta, kako bi se primenilo konačno lečenje. Međutim, ako su ispunjeni određeni uslovi, moguće je primeniti ranu terapiju III klase, da bi se poboljšali okluzalni odnosi i obezbedila dobra osnova za dalji rast. Cilj ovog rada bio je da se prikaže terapijski efekat dva slučaja malokluzije III klase u ranom uzrastu pomoću različitih ortodontskih aparata: Delerove maske i Frenklovog regulatora funkcije tip 3. Kod pacijentkinje koja je tokom lečenja nosila Delerovu masku gornja vilica je zarotirana unapred i nadole, jer je ugao delovanja sile modifikovan da bude skoro 45 stepeni. Na kraju lečenja postignut je znatno bolji izgled lica. Pomeranjem gornje vilice unapred postignut je prav profil, dok je pomeranje nadole dovelo do usklađivanja visine srednje trećine lica sa gornjom i donjom. Kod pacijenta kod kojeg je tokom lečenja primenjena terapija Frenklovim regulatorom funkcije tip 3 do korekcije obrnutog preklopa sekutića došlo je kombinacijom razvijanja premaksile i protruzije sekutića.

AB  - Introduction Dentofacial deformity, a deviation from normal facial proportions and dental relationships, is corrected by jaw repositioning in all three spatial planes, which changes the position and tension of the surrounding tissues, bones and muscles. These changes may also affect the dimensions of the pharyngeal airways (PA). Objective The aim of this study was to evaluate and compare three-dimensional PA changes in patients treated by a combination mandibular set-back/maxillary advancement versus patients that had bimaxillary advancement with genioplasty. Methods The sample consisted of 7 patients treated by combined mandibular set-back/maxillary advancement and 7 patients treated with bimaxillary advancement surgery. Nasopharyngeal (NP) volume, oropharyngeal (OP) volume and the area of maximum constriction (AMC) in the OP were measured on CbCt scans (2 mA/120 kV/12'' FOV) taken before (T1 ) and 3 months after surgery (T2). Paired samples t-test was used for analyzing statistical significance of changes (p≤0.05). Results OP volume and AMC increase after bimaxillary advancement was statistically significant, while for the mandibular set-back group the increase was non-significant. NP volume was not reduced in any of the two groups. No significant differences in PA dimensions were found between groups at neither T1 nor T2 time points. Conclusion Results suggest that the combination of mandibular set-back/maxillary advancement did not reduce airway dimensions, while bimaxillary advancement surgery led to a statistically significant increase in the OP dimensions.
AB  - Uvod Dentofacijalni deformiteti predstavljaju odstupanje u odnosu na normalne proporcije lica i dentalne odnose. Leče se repozicioniranjem vilica u sve tri ravni prostora, što menja položaj i napetost okolnih mekih tkiva, kostiju i mišića. Ove promene mogu da utiču na veličinu faringealnih vazdušnih puteva. Cilj rada Cilj studije je bio da se procene i uporede trodimenzionalne promene faringealnih vazdušnih puteva kod osoba lečenih retropozicioniranjem mandibule uz pomeranje maksile unapred u odnosu na one lečene pomeranjem obe vilice unapred uz genioplastiku. Metode rada Ispitanike je činilo sedam pacijenata lečenih kombinacijom retropozicioniranja mandibule i anteriornog pozicioniranja maksile i sedam pacijenata lečenih bimaksilarnim anteriornim pozicioniranjem. Zapremine nazofarinksa, orofarinksa i površina najužeg dela orofarinksa mereni su na CBCT snimcima (2 tL/120 kV/12' FOV) napravljanim pre operacije (T1) i tri meseca nakon hirurške korekcije (T2). Studentov t-test za uparene uzorke korišćen je za analizu statističke značajnosti promena (p≤0,05). Rezultati Zapremina orofarinksa i površina najužeg dela orofarinksa povećale su se u obe grupe, i to statistički značajno kod ispitanika lečenih bimaksilarnim anteriornim pozicioniranjem, a statistički beznačajno kod ispitanika lečenih kombinacijam retropozicioniranja mandibule i anteriornog pozicioniranja maksile. Ni u jednoj grupi nije došlo do smanjenja zapremine nazofarinksa. Ni pre ni posle terapije nisu uočene značajne razlike u veličini vazdušnih puteva između grupa. Zaključak Rezultati ukazuju na to da retropozicioniranje mandibule uz anteriorno pozicioniranje maksile nije smanjilo dimenzije vazdušnih puteva, dok je bimaksilarno anteriorno pozicioniranje dovelo do statistički značajnog povećanja veličine orofarinksa.

AB  - Structured Abstract Objective To evaluate and compare three-dimensional pharyngeal airway changes in orthodontic patients treated with and without extractions. Material and Methods Pharyngeal airway was analyzed for 31 subjects (15 males, 16 females) treated with extractions of four first premolars and 31 age- and gender-matched controls (15 males, 16 females) treated without extractions. The mean age of subjects was 12.97 +/- 1.15years at the beginning and 15.69 +/- 1.28years at the end of treatment. The mean age of controls was 12.86 +/- 0.74years at the beginning and 15.18 +/- 0.86years at the end of treatment. Nasopharyngeal (NP) and oropharyngeal (OP) volumes, area of maximum pharyngeal constriction (AMPC), and upper arch perimeter were measured on T0 and T1 cone beam computed tomography (CBCT) scans. Paired samples t-test was used for analyzing statistical significance of changes (p0.05). Results There were no statistically significant differences in the pharyngeal airway values between the extraction and non-extraction groups at neither T0 nor T1. The extraction group showed a statistically significant increase for NP and OP volumes and AMPC values. Such increase was also noted in the non-extraction group, without statistical significance for AMPC values. Conclusions The findings suggest that an extraction or non-extraction choice for orthodontic treatment would not affect the pharyngeal airway.

AB  - Three-dimensional (3D) nature of the human body and head had been analysed ever since the antient times. At the beginning of the 20th century plaster was the basic diagnostic material used for representing dentofacial morphology, so most orthodontists used plaster study models to analyse the dentition and the alveolar bone. Some more ambitious clinitians, amongst them Calvin Case, even suggested the use of facial moulages in order to capture the pre- and posttreatment facial morphology. Introduction of cephalometrics to orthodontics in the mid 1920-ies enabled describing craniofacial morphology and growth, predicting growth, planning treatment and evaluating treatment outcomes. However, even back in the 1960-ies orthodontists recognized a need for 3D cephalometrics. Craniofacial CBCT scanners were developed at the beginning of the 21st century in order to overcome limitations of conventional CT scanners. CBCT enabled us to analyse skeletal and soft-tissue structures of our patients in all three dimensions of space and as 3D volumes using the data from a single scan which exposes the patient to significantly less radiation then the conventional CT scanner. The aim of this doctoral dissertation was to analyse upper airway and facial soft-tissue changes of adolescent patients treated orthodontically with or without extractions, and adult patients treated by combined orthodontic-surgical treatment. The sample consisted of 107 patients treated at the Department of Orthodontics and the University Hospital of the Case Western Reserve University in Cleveland, OH, USA. All patients were scannen before and after treatment, as a part of the standard diagnostic and therapeutic procedure, using an adjusted Hitachi CB MercuRay scanner (2 mA, 120 kV, 12‖ FOV, F Mode). Depending on the type of treatment patients were divided into three groups. Cephalometric analysis, analysis of upper, or pharyngeal (PAS-Pharyngeal Airway Space) airways (Nasopharyngeal (NP) and Oropharyngeal (OP) Volumes and Area of Maximal Pharyngeal Constriction (AMPC)) and facial soft-tissue analysis (both in 2D and 3D) were preformed for all patients...
AB  - Trodimenzionalnost (3D) ljudskog tela proučavana je još od antičkog vremena.

Neki ambiciozniji ortodonti, meĎu kojima i Calvin Case predlagali su pravljenje gipsanih modela lica, kako bi se zabeleţile karakteristike lica pre i posle terapije. Kefalometrija, koja je uvedena u ortopediju vilica sredinom dvadesetih godina prošlog veka, omogućila je opisivanje morfologije i rasta kraniofacijalnog skeleta, predviĎanje rasta, planiranje terapije i evaluaciju ishoda terapije. Ipak, potreba za trodimenzionalnom kefalometrijom prepoznata je još sredinom prošlog veka. Kraniofacijalni CBCT skeneri razvijeni su početkom XXI veka kako bi se prevazišla ograničenja konvencionalnih CT skenera. CBCT je omogućio ortodontima da analiziraju skeletne i mekotkivne strukture svojih pacijenata u sve tri dimenzije prostora i kao 3D strukture, i to pomoću samo jednog skena koji pacijenta izlaţe značajno manjoj dozi zračenja u odnosu na CT skener. Cilj ove doktorske disertacije bio je da se procene promene na nivou gornjih vazdušnih puteva i mekih tkiva lica adolescentnih pacijenata tretiranih ekstrakcionom i neekstrakcionom ortodontskom terapijom i odraslih pacijenata tretiranih kombinovanom ortodontsko-hirurškom terapijom. Uzorak se sastojao od 107 pacijenata, izdvojenih iz grupe od 141 pacijenta tretiranog na Stomatološkom fakultetu i u Univerzitetskoj bolnici Case Western Reserve Univerziteta, u Klivlendu, SAD. Svi pacijenti su snimljeni pre i posle terapije prilagoĎenim Hitachi CB MercuRay skenerom (2 mA, 120 kV, 12-inčno polje pregleda u F Modu) u okviru standardnog dijagnostičkog i terapeutskog postupka. U zavisnosti od vrste terapije, pacijenti su podeljeni u tri grupe. Za sve pacijente je uraĎena kefalometrijska analiza, merene su dimenzije gornjih vazdušnih puteva (zapremine nazofarinksa (NP) i orofarinksa (OP) i površina najuţeg dela farinksa (AMPC – Area of Maximal Pharyngeal Constriction) i dimenzije mekih tkiva lica, kako dvodimenzionalne, tako i trodimenzionalne...

Kefalometrija, koja je uvedena u ortopediju vilica sredinom dvadesetih godina prošlog veka, omogućila je opisivanje morfologije i rasta kraniofacijalnog skeleta, predviĎanje rasta, planiranje terapije i evaluaciju ishoda terapije. Ipak, potreba za trodimenzionalnom kefalometrijom prepoznata je još sredinom prošlog veka. Kraniofacijalni CBCT skeneri razvijeni su početkom XXI veka kako bi se prevazišla ograničenja konvencionalnih CT skenera. CBCT je omogućio ortodontima da analiziraju skeletne i mekotkivne strukture svojih pacijenata u sve tri dimenzije prostora i kao 3D strukture, i to pomoću samo jednog skena koji pacijenta izlaţe značajno manjoj dozi zračenja u odnosu na CT skener. Cilj ove doktorske disertacije bio je da se procene promene na nivou gornjih vazdušnih puteva i mekih tkiva lica adolescentnih pacijenata tretiranih ekstrakcionom i neekstrakcionom ortodontskom terapijom i odraslih pacijenata tretiranih kombinovanom ortodontsko-hirurškom terapijom. Uzorak se sastojao od 107 pacijenata, izdvojenih iz grupe od 141 pacijenta tretiranog na Stomatološkom fakultetu i u Univerzitetskoj bolnici Case Western Reserve Univerziteta, u Klivlendu, SAD. Svi pacijenti su snimljeni pre i posle terapije prilagoĎenim Hitachi CB MercuRay skenerom (2 mA, 120 kV, 12-inčno polje pregleda u F Modu) u okviru standardnog dijagnostičkog i terapeutskog postupka. U zavisnosti od vrste terapije, pacijenti su podeljeni u tri grupe. Za sve pacijente je uraĎena kefalometrijska analiza, merene su dimenzije gornjih vazdušnih puteva (zapremine nazofarinksa (NP) i orofarinksa (OP) i površina najuţeg dela farinksa (AMPC – Area of Maximal Pharyngeal Constriction) i dimenzije mekih tkiva lica, kako dvodimenzionalne, tako i trodimenzionalne...",

AB  - Introduction. A successful treatment outcome in dentofacial deformity patients commonly requires combined orthodontic-surgical therapy. This enables us to overcome functional, aesthetic and psychological problems. Since most patients state aesthetics as the primary motive for seeking therapy, cephalometric predictions of treatment outcome have become the essential part of treatment planning, especially in combined orthodontic-surgical cases. Objective. The aim of this study was to evaluate the validity and reliability of computerized orthognathic surgery outcome predictions generated using the Nemotec Dental Studio NX 2005 software. Methods. The sample of the study consisted of 31 patients diagnosed with mandibular prognathism who were surgically treated at the Hospital for Maxillofacial Surgery in Belgrade. Investigation was done on lateral cephalograms made before and after surgical treatment. Cephalograms were digitized and analyzed using computer software. According to measurements made on superimposed pre- and postsurgical cephalograms, the patients were retreated within the software and the predictions were assessed by measuring seven angular and three linear parameters. Prediction measurements were then compared with the actual outcome. Results. Results showed statistically significant changes between posttreatment and predicted values for parameters referring to lower lip and mentolabial sulcus position. Conclusion. Computerized cephalometric predictions for hard-tissue structures in the sagittal and vertical planes, as well as the VTO parameters, generated using the Nemotec Dental Studio NX 2005 software are reliable, while lower lip and mentolabial sulcus position predictions are not reliable enough.

Kako najveći broj pacijenata navodi estetsku promenu kao primarni motiv lečenja, kefalometrijsko predviđanje ishoda je važan deo planiranja terapije, posebno kod složenih slučajeva. Cilj rada.

Istraživanje je izvedeno na profilnim teleradiogramima snimljenim pre i posle hirurške intervencije. Nakon digitalizacije snimaka izvršena je kompjuterizovana kefalometrijska analiza. Na osnovu merenja određenih horizontalnih i vertikalnih rastojanja na preoperacionim i postoperacionim radiogramima, urađena je simulacija hirurških korekcija i na njima izmerena vrednost sedam angularnih parametara i tri linearna parametra, čija je vrednost upoređena s vrednostima na postoperacionim radiogramima. Rezultati. Ustanovljene su statistički značajne razlike između postoperacionih i predviđenih vrednosti za parametre koji govore o položaju donje usne i mentolabijalnog sulkusa. Zaključak. Kompjuterizovana kefalometrijska predviđanja položaja čvrstotkivnih struktura u sagitalnoj i vertikalnoj ravni, kao i VTO parametara, dobijena u okviru korišćenog programa su pouzdana, dok su predviđanja položaja donje usne i mentolabijalnog sulkusa nedovoljno pouzdana.

AB  - Background: Fibronectin (FN) can bind to immunoglobulins (Ig), influencing both the normal clearance and abnormal deposition of circulating immune complexes. This study focuses on the possible interaction between FN and IgG present in gingival crevicular fluid (GCF) of periodontitis patients and periodontally healthy controls, with the aim to determine whether such interaction may be connected with the glycosylation profile of IgG and, thus, consequentional in accumulation of proinflammatory IgG in periodontal pockets. Methods: The study included 30 patients with initial or advanced periodontitis, and 13 periodontally healthy subjects. GCF IgG was purified and analyzed for the presence of FN and its fragments and for galactose expression. Results: IgG isolated from GCF contained FN, which was bound to the IgG heavy chains. IgG from GCF of advanced periodontitis patients contained high levels of hypogalactosylated IgG, and bound more FN than IgG from GCF of the other two groups, which contained low levels of this glycoform. FN was in a degraded form in GCF from all studied patients, and a fragment of 48- to 53-kDa molecular mass seemed to be the sole one linked to IgG. Conclusions: IgG and the FN fragment of 48 to 53 kDa in GCF of periodontitis patients and periodontally healthy subjects are physically connected. This fragment was linked to the heavy chains of IgG and the reaction seemed to be particularly intensive with IgG from advanced periodontitis, which contained significantly less galactose in its sugar chains.

AB  - The use of information technology (IT) in dentistry is far ranging. In order to produce a working document for the dental educator, this paper focuses on those methods where IT can assist in the education and competence development of dental students and dentists (e.g. e-learning, distance learning, simulations and computer-based assessment). Web pages and other information-gathering devices have become an essential part of our daily life, as they provide extensive information on all aspects of our society. This is mirrored in dental education where there are many different tools available, as listed in this report. IT offers added value to traditional teaching methods and examples are provided. In spite of the continuing debate on the learning effectiveness of e-learning applications, students request such approaches as an adjunct to the traditional delivery of learning materials. Faculty require support to enable them to effectively use the technology to the benefit of their students. This support should be provided by the institution and it is suggested that, where possible, institutions should appoint an e-learning champion with good interpersonal skills to support and encourage faculty change. From a global prospective, all students and faculty should have access to e-learning tools. This report encourages open access to e-learning material, platforms and programs. The quality of such learning materials must have well defined learning objectives and involve peer review to ensure content validity, accuracy, currency, the use of evidence-based data and the use of best practices. To ensure that the developers' intellectual rights are protected, the original content needs to be secure from unauthorized changes. Strategies and recommendations on how to improve the quality of e-learning are outlined. In the area of assessment, traditional examination schemes can be enriched by IT, whilst the Internet can provide many innovative approaches. Future trends in IT will evolve around improved uptake and access facilitated by the technology (hardware and software). The use of Web 2.0 shows considerable promise and this may have implications on a global level. For example, the one-laptop-per-child project is the best example of what Web 2.0 can do: minimal use of hardware to maximize use of the Internet structure. In essence, simple technology can overcome many of the barriers to learning. IT will always remain exciting, as it is always changing and the users, whether dental students, educators or patients are like chameleons adapting to the ever-changing landscape.

AB  - Treatment plan in contemporary orthodontics cannot be imagine without analyzing soft tissue facial characteristics besides assessment of jaw and dental relationships. Aim. Using a questionnaire, we aimed this study at establishing facial characteristics, in relation to sagittal and vertical facial ratios, which are considered aesthetically acceptable, and which could be altered by the means orthodontic treatment. Material and Method. The research was conducted in persons from 23 to 30 years of age whose photographs were taken in standard conditions. Photographs of three patients with different facial profiles were chosen (Class I, Class II and Class III). Every photo was modified in six new profiles by changing facial features. This included mesial and distal shift of maxilla and mandible, as well as increase and decrease of lower facial height. Results. The results showed that straight profile, which is most often present in normal jaw relationships, is considered the most beautiful, furthermore slightly convex profiles are also considered very attractive. Convex profile is connected with distal jaw relationship and its intensity affects facial attractiveness. Concave profile in patients with mesial jaw relationship is aesthetically the least acceptable.
AB  - Savremena ortodoncija se ne može ni zamisliti bez plana terapije koji pored odnosa vilica i položaja zuba treba da obuhvata i karakteristike mekih tkiva lica. Cilj ovog istraživanja je bio da se na osnovu ankete ustanove karakteristike lica u zavisnosti od sagitalnih i vertikalnih odnosa vilica, koje se smatraju estetski prihvatljivim, a na koje se tokom ortodontske terapije može delovati. Materijal i metod: Istraživanje je sprovedeno na osobama uzrasta od 23 do 30 godina koje su snimane digitalnim aparatom u standardnim uslovima. Odabrani su desni profilni snimci tri ispitanika: po jednog sa prvom, drugom i trećom okluzalnom klasom. Ovi snimci su kompjuterski obrađeni tako da je svaki od njih modifikovan u novih šest oblika. Modifikacije su podrazumevale mezijalno i distalno pomeranje maksile i mandibule, kao i povećanje i smanjenje visine donje trećine lica. Rezultati su pokazali da se ravan profil koji je najčešće prisutan kod eugnatih odnosa vilica smatra najlepšim, mada se i blago konveksni profil vrlo često smatra atraktivnim. Konveksni profil se sreće kod distalnih odnosa vilica i u zavisnosti od stepena izraženosti utiče na atraktivnost lica. Mezijalni odnos vilica, kada mandibula prevazilazi u sagitalnom pravcu maksilu, najčeće vodi konkavnom profilu koji je estetski najmanje prihvatljiv.
