Long-term success of endodontic treatment is strictly dependent on proper shaping and cleaning of the root canal system followed by obturation of entire prepared space. Anatomical variations should be considered during radiographic and clinical evaluation as parts of endodontic treatment. A mandibular premolar with three canals is quite rare and such a tooth requires special canal preparation a...

Familiarity with the normal and abnormal anatomy of the root canal system is essential for successful root canal treatment. The possibility of concomitant three-rooted and three- canalled maxillary and mandibular premolars are extremely rare. The purpose of this paper was to report a case with a three-rooted maxillary first premolar and two three-rooted mandibular premolars.

Dens invaginations are a rare developmental defect most commonly affecting maxillary lateral incisors, with very few reported cases in mandibular teeth. We describe a rare case of bilateral first mandibular premolar dens invaginations type I, where apparently health teeth presented with periapical pathology.

Distal displacement of the tooth germ mandibular second premolar (MnP2) leads to its impaction and obturation eruption path first molar delaying eruption. The present case report describes treatment 2 cases guidance for distally displaced developing MnP2 that caused delayed molar. Intentional extraction primary predecessor results in mesial shift MnP2. However, unfavorable distal ectopic after ...

Overeruption of maxillary molars due loss of opposing teeth creates occlusal and functional interferences. Before reconstruction can be initiated, intrusion of overerupted molars becomes essential. This report illustrates treatment of overerupted maxillary premolar and molar via direct use of miniscrew anchorage. A 24-year old female had lost first and second left mandibular molars due to pulpa...

This paper presents two cases of late developing supernumerary premolars. Case 1 is a female patient with nonsyndromic multiple supernumerary teeth located in the maxillary right premolar-molar region, maxillary left premolar region, and the mandibular right and left premolar regions. In this patient surgical removal of all supernumerary teeth was carried out to avoid complications during ortho...

Introduction: The main goal of root canal treatment is to prevent or heal formation of apical periodontitis. Complexity of root canal anatomy presents clinical challenges related to treatment outcome. The aim of this study was to investigate the morphology of the root canal system of mandibular 2 nd premolar in north Indian subpopulation using periapical radiographs and CT Dentascan. No such st...

Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material Methods: In this retrospective cross-sectional study, CBCT images 314 patients comprising 346 maxillary 412 mandibular first (FPM) teeth, 298 387 second (SPM) were analyzed to the number roots, morphology, based on Vertucci's classifica...

PURPOSE Bone density at implant placement site is a key factor to obtain the primary stability of the fixture, which, in turn, is a prognostic factor for osseointegration and long-term success of an implant supported rehabilitation. Recently, an implant motor with a bone density measurement probe has been introduced. The aim of the present study was to test the objectiveness of the bone densiti...
