The phenomenon of supernumerary canals in the palatal roots of the first upper molars

Abstract

U radu se raspravlja o pojavi prekobrojnih palatinalnih korjenova i dvostrukih kanala u palatinalnom korijenu prvog kutnjaka. U ispitivanje je uzeto postupkom slučajnog uzorka 443 prvih gornjih kutnjaka i pripremljeno za analizu. Ustanovljena je pojava prekobrojnih palatinalnih korjenova u 0,5% uzoraka, a pojava prekobrojnih kanala u palatinalnom korjenu u 0,9% ispitivanih uzoraka. Uz pojavu prekobrojnih korjenova i korjenskih kanala dan je i prikaz unutarnje anatomije pulpne komorice te smještaja korjenova i korjenskih kanala u palatinalnom korijenu.The phenomenon of supernumerary palatine roots and supernumerary canals in the palatal root of the first upper molar has been studied. In 2 of the 443 first upper molars examined, a supernumerary palatine root was found (incidence 0.5%). Supernumerary canals in the palatine root were detected in 4 samples, i.e. in 0.9% of the cases. The phenomenon of supernumerary roots and root canals is discussed and a presentation is made of the internal anatomy of the pulp chamber and of the location of roots and root canals in the palatine root
