AB  - The aim of this paper was to analyse the characteristic properties of different commercially available NiTi archwires (diameter 0.014 ''). Characteristic properties were determined by using DSC analysis for identification of phase temperatures and a tensile test for obtaining the mechanical properties, while semi-quantitative EDS analysis was used for their chemical composition. Analysis of phase temperatures showed that nickel- titanium orthodontic archwires, in the austenitic phase, were exhibiting superelastic effect in the oral environment (T=37 degrees C). The uniaxial stress-strain curves showed different values for the beginning and the end of loading due to the stress and transformation range. The investigation of the chemical composition showed an equiatomic NiTi alloy. The aim of the first phase of biocompatibility assessment of Ni-Ti archwires was to investigate the potential cytotoxicity on a model of rat thymocytes, where a direct contact exists between the archwire and the cells. The test was chosen because of the high sensitivity of thymocytes to proapoptotic stimuli and because the test includes the culture of non-adherent, non-proliferating cells, such as thymocytes, which is much more convenient for the evaluation of a material's cytotoxicity in direct contact, compared to the adherent cells such as fibroblasts. The experiment was designed to cultivate the Ni-Ti archwire samples with rat thymocytes, using different surface-over-volume ratios of the archwires in complete medium. The cytotoxic effect was evaluated by measuring the apoptosis. The aim of the second phase of the study was to investigate further the cytotoxic effects of Ni-Ti archwires in the short-term (24h) and long-term (48h) cultures of rat's thymocytes, which are highly sensitive to pro-apoptotic stimuli, where a direct contact exists between archwires and the cells.

AB  - Introduction Patients with craniomandibular disorders suffer from hypertonic, fatigued and painful masticatory muscles. This condition can lead to limitation of mandibular jaw movements. All of these symptoms and signs are included in myofascial pain dysfunction syndrome. Transcutaneous electrical nerve stimulation (TENS) has been used for treatment of these patients. Objective The aim of this study was to assess the effect of TENS therapy on chronic pain reduction in patients with the muscular dysfunction symptom. Methods In order to evaluate the effect of TENS therapy before and after the treatment, Craniomandibular Index (Helkimo) was used. Pain intensity was measured by VAS. Patients had TENS treatment over two-week period. BURST TENS modality was used. Current intensity was individually adjusted. Results Two patients did not respond to TENS therapy. Complete pain reduction was recorded in 8 patients, while pain reduction was not significantly different after TENS therapy in 10 patients. Conclusion TENS therapy was confirmed as therapeutic procedure in orofacial muscle relaxation and pain reduction.
AB  - Uvod Hiperaktivnost mastikatorne muskulature, pojačan tonus mišića, zamor i bol, uz smanjenje opsega funkcijskih kretnji donje vilice, jesu znaci i simptomi miofascijalnog bolnog disfunkcijskog sindroma. Različiti terapijski modaliteti koriste se u lečenju, među kojima je i terapija transkutanom električnom nervnom stimulacijom (TENS). Cilj rada Cilj rada bila je klinička potvrda efekta terapije TENS na intenzitet hroničnog bola kod osoba sa simptomima disfunkcije mišića. Metode rada Radi procene terapije TENS korišćen je Helkimov kraniomandibularni indeks. Za kvantifikaciju intenziteta bola pre i posle lečenja primenjena je vizuelno-analogna skala (VAS). Pacijenti su podvrgnuti terapiji tri puta nedeljno u trajanju od 40 minuta tokom dve nedelje. Primenjen je modalitet burst (kratki impulsi dužine 10 ms i frekvencije 2-3 Hz) uz individualno podešavanje intenziteta strujnog impulsa. Rezultati Nisu primećeni negativni sporedni efekti terapije TENS. Potpuno smanjenje intenziteta bola zabeleženo je kod osam ispitanika. Kod 10 ispitanika smanjenje bola nije bilo značajno. Dva pacijenta nisu reagovala na primenjenu terapiju. Zaključak Terapija TENS se preporučuje osobama s manjim stepenom kraniomandibularnih disfunkcija bez obzira na intenzitet bola.

AB  - The all-ceramic endocrowns are one piece restoration used in the therapy of endodontically treated teeth, usually, with a decreased vertical dimension of the tooth crown. The aim of this paper is to describe two techniques of the making of endocrowns using case studies and to present the advantages and disadvantages of both techniques by way of their comparison. Chair-side production with the Cerec CAD-CAM system and pressing of the ceramic with the Empres II system was used for the production of the endocrowns. Cerec CAD-CAM and Empres II systems yielded equally good results in the production of the endocrowns, in terms of their functionality, retention, aesthetic and duration. The basic difference between them is the length of the endocrown production procedure as the Cerec CAD-CAM system makes it possible to apply the treatment during a single visit using a wide range of materials….

Cilj ovog rada je bio da se na slučajevima iz kliničke prakse predstave dve tehnike izrade endokruna i da se poređenjem karakteristika tih sistema ukaže na njihove prednosti i nedostatke. Kod jednog pacijenta, za izradu endokruna korišćena je jednoseansna izrada Cerec CAD-CAM sistemom, a kod drugog presovanje keramike Empres II sistemom. Obe tehnike, i Cerec CAD - CAM i Empress II sistem, pokazale su podjednako dobre rezultate, u smislu funkcionalnosti, retencije, estetike i dugotrajnosti endokruna. Osnovna razlika je u trajanju procedure izrade endokruna jer Cerec CAD - CAM sistem omogućava tretman u samo jednoj poseti pacijenta i koristi širu paletu gradivnih materijala.
