Pojavnost akcesomih kanalića na srednjoj i koronarnoj trećini korijena prednjih zuba

Lateralni kanalići na zubu mogu stomatologu stvarati probleme pri dijagnosticiranju pulpitičnih boli nakon endodoncije, a znanje o njima znatno olakšati rad. Ovo ispitivanje provedeno je da bi se proširile spoznaje o morfologiji zuba i time poboljšao rad stomatologa. Lateralni kanalići proučavani su na slučajnom uzorku od 110 trajnih, jednoko- rijenih, prednjih gornjih i donjih zuba. U ispitivanju upotrebljene su metode prebrojavanja, promatranja pod povećalom i bojenja. Utvrđeno je postojanje lateralnih kanalića koji se otvaraju na srednjoj trećini korijena kod 5 zuba (4,5%). Statističkom raščlambom utvrđeno je da ispitivanu pojavu možemo očekivati u populaciji s 95% vjerojatno- sti u intervalu od 0,7% do 8,3%. Ispitivanu pojavu potrebno je potanje ispitati ne samo na prednjim zubima već i na svim skupinama zuba.
Although accessory canals can cause problems in diagnosing post endodontic pulpal pain adequate knowledge about it can make the work easier. This investigation was carried out in order to improve knowledge about teeth morphology and to improve the work of dentists. Accessory canals were investigated on a accident sample of 110 permanent, singlerooted, frontal upper and lower teeth. Methods used in this investigation were: counting, magnifying, observing and colouring. It was established that accessory canals appear on the middle third of the root surface on upper and lower frontal, permanent, singlerooted teeth in 4.5% cases (5 teeth). Statistically, it was established that we could expect the frequency of accessory canals on the middle third of the root surface in the population ranging from 0.7% to 8.3%, with 95% probability. The problem investigated should be thoroughly studied in the future, not only on frontal teeth but all groups of teeth.
