Abstract
The complex root canal system of maxillary second premolars shows variations among different populations. The aim of this study was to evaluate the root canal morphology of second maxillary premolars in the romanian population. The number of roots, root canals and the root canal configuration were investigated using radiographs in both buccal-oral and mesio-distal incidence. They were categorized using Weine’s classifi cation. Among the 480 teeth, 90.83% had one root and 66.67% one root canal. The frequency of secondary maxillary premolars with two root canals (33.12%) shouldn’t be underestimated. Knowing the variations of the internal root canal morphology of maxillary second premolars in a certain population can lead the clinician to a better approach of the endodontic treatment.

Vizualizarea preoperatorie cu ajutorul radiografiilor excentrice şi a CBCT-ului constituie premisa aprecierii corecte a morfolgiei premolarilor superiori pentru a asigura un tratament endodontic corespunzător, datorită identificării tuturor canalelor radiculare
Summary
The complex root canal system of maxillary second premolars shows variations among different populations. Premolarul doi maxilar cu o singură rădăcină relevă în 73,40% un canal cu un foramen (Tip I Weine), în 12,61% două canale care confluează, prezentând un singur foramen apical (Tip II Weine), în 10,78% din cazuri se întâlnesc două canale cu FIGURA 1. Premolar doi superior – fotografiere şi radiografiere în două incidenţe două foramene separate (Tip III Weine) şi în 3,21% un canal care se divide în treimea medie sau apicală, având două foramene apicale (Tip IV Weine).
