OBJECTIVE The aim of the present study is to assess the root and root canal morphology of maxillary and mandibular premolars in a Turkish population by using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this study, CBCT images of 2134 premolars (987 maxillary, 1147 mandibular) were obtained from 404 patients. Details of gender, age, number of roots and canals, and canal conf...

Success of endodontic treatment requires the knowledge and morphology of root canal anatomy. Undetected additional canals in mandibular premolar is a common reason for endodontic failure. This presents with diagnostic difficulty and subsequent flare ups and poor prognosis. Location of additional canals is the key to successful endodontic management. This case report describes endodontic managem...

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...

The mandibular second premolar is usually described as a single rooted tooth with a single root canal. However, two root canals may be found but the occurrence of two roots is extremely rare. The reported studies have shown 0.3% prevalence of two roots in mandibular second premolars. This report describes an unusual case of a thirteen year old female patient with bilateral two rooted mandibular...

Ankylosis of primary mandibular molars has been routinely found to be associated with various developmental disturbances in permanent dentition such as aplasia of the succedaneous tooth, ectopic eruption of the premolar, infraoclusion of the ankylosed tooth leading to tipping of the first permanent molar etc. This article describes a rare case where there was ankylosis of a mandibular second pr...

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.

This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. Treatment consisted of the extraction of the impacted second primary ...

introduction: it is essential for clinicians to have knowledge about root canal configuration, although its morphology varies largely in different ethnicities and even in different individuals within the same ethnic group. the current study reviewed the root canal configuration of root canals in mandibular first and second premolars among iranian population based on independent epidemiological ...

PATIEN'l' J. Z., a white boy 13 years 9 months of age, had a Class II, Division 1 malocclusion. This diagnosis could be determined only in the canine area, since no mandibular molars were present on either the right or the left side. The maxillary arch was normal in width and in protraction. The maxillary right second premolar was blocked out lingually and rotated mesially, and the maxillary le...
