The dental literature contains a small number of reports of primary multirooted anomalies and even fewer reports on the clinical significance of these findings. Specifically, there are fewer reports of primary radicular anomalies than of permanent radicular anomalies. Knowledge of the size, morphology and variation of the roots and root canals of a primary tooth is useful in performing endodont...

Introduction: The purpose of this study was to evaluate the sealing ability of dentin bonding agents in root canals obturated with gutta-percha and MTA. Methods: Forty-five single rooted human premolar teeth were decoronated so that remaining root portions were 12 mm in length. The samples were divided randomly into three experimental (n=13) and two control groups (n=3). All teeth were instrume...

Aim: To compare the effect of ultrasonic, sonic and rotary sealer activation techniques on depth penetration in dentinal tubules. Materials Methods: Freshly extracted 60 single rooted human permanent mandibuar premolar with mature apex were collected. A size 10 no. K file (Dentsply Maillefer) was introduced into each canal. The irrigation procedure accomplished by using 2ml 5.25% NAOCl for used...

this article describes a clinical case of mandibular second premolar with three separated canals in apical third of the root that are diagnosed and endodontically treated. sound knowledge of root canal anatomy and morphology, tactile examination of canal walls, critical interpretation of radiographs and high magnification examination are essential elements of success in complicated root canal t...
