Introduction: A thorough understanding of root canal anatomy and morphology is required for achieving high levels of success in endodontic treatment. The possible anatomic configurations of premolars are well documented in the literature, except for the small incidence of bilateral multi-rooted maxillary and mandibular premolars with three canals. Objective: To report a rare case of bilateral m...

Intraosseous migration is an unusual developmental dental anomaly, which demonstrates horizontal movement of unerupted teeth only affecting the permanent dentition of the lower jaw. Mandibular second premolar is the most common impacted tooth after the third molars and maxillary canines. Distal migration of the second premolar is rare and early loss of the permanent first molar is one of the mo...

AIM To report cases with morphologic variations in mandibular premolars. BACKGROUND Mandibular premolars have earned the reputation for having aberrant anatomy. The occurrence of three canals with three separate (type V, Vertucci) foramina in mandibular premolars is very rare. In this report, three cases are presented involving the root canal treatment of mandibular premolars with three diffe...

BACKGROUND Mixed dentition space analysis forms an important part of orthodontic diagnosis and treatment planning. Regression equations are widely used for mixed dentition analysis which can vary among races. This study aimed to find out the new regression equation in estimating the size of unerupted canines and premolars for Nepalese Brahmins/Chhetris. METHODS Hundred Nepalese Brahmins/Chhet...

mandibular premolars have earned a reputation for having aberrant anatomy. the occurrence of three canals with three separate foramina in mandibular premolars is very rare. if predictable treatment of a three rooted mandibular premolar is planned, precise knowledge of clinical and radiographic anatomy is absolutely necessary. these teeth may also require special shaping and obturating technique...

background and aims. it is critical to have a proper knowledge of the normal anatomy of the pulp and its variations for the success of endodontic treatment. the aim of this study was to determine the canal configuration and the prevalence of c-shaped canals in mandibular first and second premolars in a north-western iranian population. materials and methods. a total of 163 extracted mandibular ...

OBJECTIVE To evaluate the presurgical orthodontic tooth movement of mandibular teeth after dental decompensation for skeletal Class III deformities on the basis of vertical skeletal patterns. METHODS This cohort was comprised of 62 patients who received presurgical orthodontic treatment. These patients were divided into 3 groups according to their vertical skeletal patterns. Changes in the po...

OBJECTIVE The aim of this study was to assess the prevalence and pattern of congenital missing teeth in the permanent dentition (excluding wisdom teeth), among Turkish children in a 4-year period (2009-2012). METHODS The study group comprised 1658 children (873 girls, 785 boys). The children were examined in Department of Pediatric Dentistry, Dental School of Marmara University. A chi square ...

This clinical article presents and describes the endodontic treatment of a mandibular second premolar exhibiting a total of four separate root canals. This incidence in mandibular second premolars is particularly rare in the international endodontic literature. Only some infrequent cases of mandibular second premolars with four canals have been presented; however, this was done without the use ...
