INTRODUCTION Maxillary canine-first premolar transposition (Mx.C.P1) is an uncommon dental positional anomaly that may create many orthodontic problems from both esthetic and functional points of view. OBJECTIVE In this report we show the orthodontic management of a case of Mx.C.P1 associated with bilateral maxillary lateral incisor agenesis and unilateral mandibular second premolar agenesis ...

Anatomical variations in root canal morphology are an enigma and it is this variability, which is often a complicating factor in a successful root canal treatment. To achieve success in endodontic therapy it is imperative that all the canals are located, cleaned and shaped and obturated three dimensionally. Maxillary first premolar having three separate roots has an incidence of 0.5-6%. Even ra...

Running title: Root and canal morphology of maxillary first premolar teeth Abstract Aim : To determine the variations in the root and canal morphology of the maxillary first premolar teeth in a Ugandan population. Methodology : Extracted maxillary first premolar teeth (n = 202) were evaluated in this study. The specimens had their pulp chambers de-roofed. They were decalcified in nitric acid an...

Tooth transposition is a severe disturbance of tooth order and eruptive position, involving certain teeth that may occur at any of the several sites in the mouth. Maxillary canine-first premolar (MxCP1) transposition is the most frequent tooth transposition. This case report presents the treatment of female patient with bilateral maxillary canine-premolar transposition. The order of transpositi...

Maxillary first premolar is most commonly a bi-rooted tooth, occasionally having three roots. It usually has two canals, but may rarely have three, which can easily be missed, demanding more attention during endodontic intervention. This paper reports this rarity of 3 roots and canals in maxillary premolar, highlighting the difficulties special care needed treatment. Careful investigation diagn...

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.

The purpose of this study was to examine how the periodontal sensory inputs of working-side maxillary posterior, teeth affect nonworking-side anterior temporalis activities at the starting jaw position of the slow-closing phase in mastication. Six subjects with normal occlusion were asked to bite an incisal block to maintain the initial jaw position of the slow-closing phase and to generate jaw...

Transposition is a dental anomaly characterized by the exchange of position between two adjacent teeth, especially in relation to their roots, or development and eruption of a tooth in a position normally occupied by a nonadjacent tooth. Transposition of the maxillary canine and first premolar has a low prevalence in the population and it primarily affects maxillary canines and premolars. The a...

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...
