AB  - Impaktirani zubi su zubi koji su prisutni u vilicama, a prošlo je vrijeme njihovog nicanja i procijenjeno je da neće nići i zauzeti fiziološko mjesto u zubnom nizu. Svi zubi u vilicama mogu biti impaktirani ali najčešće su to umnjaci i gornji očnjaci. Etiologija nastanka impakcije je lokalne, sistemske i genetske prirode. Najzastupljenija teorija je nedostatak prostora u zubnom nizu zbog redukcije vilica.
Dijagnostički plan impakcije zuba su anamneza, klinički i rendgenski pregled. Anamnestički i klinički podaci, sa jedne strane mogu biti oskudni, dok sa druge strane mogu jasno ukazivati na impakciju. Bez obzira na kliničku sliku i anamnezu, radiografski pregled je obavezan kada se sumnja na postojanje impakcije.
Radiološka dijagnostika impaktiranih zuba pomaže u definitivnom postavljanju dijagnoze, analizi položaja impaktiranog zuba, stanja okolne kosti, susjednih zuba i anatomskih detalja. Radiološke metode koje nailaze na najveću primjenu u dijagnostici impaktiranih donjih umnjaka i gornjih očnjaka su: retroalveolarni metod, ortopantomografija, okluzalni metod, frontalna projekcija donje vilice, CBCT i konvencionalni CT.
Retroalveolarni metod i ortopantomografija predstavljaju prvi korak u rendgenskoj dijagnostici impaktiranog donjeg umnjaka i gornjeg očnjaka. Buko-oralni položaj impaktiranog zuba zahtijeva metod paralakse retroalveolarnog metoda. Okluzalni metod je koristan kod impakcije gornjeg očnjaka, dok profilna projekcija omogućava prikaz buko-oralnog položaja impaktiranog umnjaka. S obzirom da dvodimenzionalni nalaz u određenim slučajevima nije dovoljan, indikovano je snimanje konvencionalnim CT-om ili CBCT-om. Rendgenski nalaz omogućuje određivanje preciznog položaja impaktiranog zuba, njegov odnos sa okolnim strukturama (mandibularni kanal, nosna šupljina, susjedni zubi, maksilarni sinus), dubinu impakcije, stanje kosti i komplikacije na susjednim zubima izazvane impakcijom. Na osnovu rendgenskog snimka pravi se plan terapije a potom i prati ishod primjenjene metode liječenja.

AB  - Purpose: The purpose of this study was to quantify the elastic properties and evaluate microscopical features of raw and boiled metatarsal bovine bone. Methods: The elastic modulus, hardness and microscopic surface of raw and cooked bovine metatarsal bone have been investigated using nanoindentation, SEM/EDX and Panasis microscope. Results: Regarding raw bovine bone, the average elastic modulus was 30.515 +/- 6,769 GPa, while the average hardness was 0.5683 +/- 0.211 GPa. When it comes to boiled bone corresponding values were 22.298 +/- 7.0303 GPa and 0.408 +/- 0.199 GPa, respectively. The values for investigated parameters were significantly higher (p  lt  0.05) in raw bone specimens. Elastic modulus significantly correlated with hardness (p  lt  0.05). EDX analysis revealed significant decrease in wt% of oxygen in boiled samples (p  lt  0.05) No significant differences could be observed in SEM images particularly when analysing in smaller magnifications. Using higher magnification, additional branching of the existing voids as well as discrete reorganization and smoother edges of nutrient canals could be observed. The surface of boiled specimens was without the presence of crusts and layering, and no microscopical evidence of structural damage could be observed. Conclusions: This study provides detailed analysis of hardness, elastic modulus of raw and cooked bovine bone and their relation and changes during exposure to temperature. These results of elastic moduli and hardness could be comparable to similar studies of bovine and human bone tissue, but the careful analysis of experimental design, type of the bone as well as limitations of the employed techniques must be carried out before interpolation of the results to other theoretical, clinical, biomaterial and archeological studies.
