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...

Purpose of this study was to investigate the most common position of the mental foramen in a selected Turkish population. The study sample included three hundred and sixty one panoramic radiographs of selected Turkish population taken in Faculty of Dentistry, University of Gazi. The most common position of the mental foramen was between the first premolar and the second premolar (71.5%). The me...

The aims of the study were to analyse the records of 26 subjects (18 females, eight males) with maxillary canine-first premolar transposition (Mx.C.P1) together with 160 subjects with a palatally displaced canine (PDC) to determine the pattern of tooth agenesis in these cases and to compare them with similar samples reported in the literature. A strong association between Mx.C.P1, lateral incis...

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...

Lower second premolars account for approximately 24 per cent of impactions, excluding third molars, even though most reports in the literature relating to impacted teeth address the maxillary canine, with relatively few reports on the lower second premolar. Conservative management involves surgical exposure of the crown, however, subsequent premolar eruption is unpredictable. A case is describe...

Eruption pattern of permanent teeth in Delhi boys was studied in 1800 well nourished children age 5-14 years. Relationship of height, weight and sexual maturity with eruption of teeth was calculated. Earliest teeth to appear were lower first molar (5.64 years) followed by lower central incisors (6.02 years), The sequence of eruption in maxilla was first molar, incisors-central then lateral, fir...

PURPOSE Patterns of von Mises stress values surrounding implants supporting fixed prostheses in the posterior edentulous maxilla were evaluated using 3-dimensional finite element analysis. MATERIALS AND METHODS Implants were placed in maxillary bone in 2 different configurations. In the first configuration, implants were placed in the first premolar, second premolar, and second molar regions;...

Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. Initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar. Some studies have observed that ect...
