This study was done to determine the prevalence of dental anomalies and facial profile abnormality and its association with the non-syndromic cleft lip and palate (CLP) as compared to the non-cleft children. A comparative cross sectional study was conducted where the case group consist of 98 non-syndromic CLP children-unilateral (UCLP) and bilateral (BCLP) who attended the Combined Clinic at Ko...

INTRODUCTION The aim of the present in vitro study was to compare the accuracy of cone-beam computed tomography (CBCT) in determining root canal morphology of mandibular first molars in comparison with staining and clearing technique. METHODS AND MATERIALS CBCT images were taken from 96 extracted human mandibular first molars and the teeth were then evaluated based on Vertucci's classificatio...

Supernumerary teeth are teeth that exceed the normal dental formula. Their prevalence in the permanent dentition is 1-14% and they occur more frequently in maxilla with a sex ratio of 2 : 1 in favor of males. They are often associated with syndromes but there are examples of nonsyndromic multiple supernumerary teeth reported in the literature. CBCT is usually the best exam for radiographic diag...

INTRODUCTION Systematic anatomical studies corroborate the anatomical complexity of the root canal system. Deviations from the norm such as multiple orifices, apical deltas, accessory canals and other variations are frequent. OBJECTIVES To present clinical reports of mandibular molars with three canals in the mesial root and two in vitro studies of the morphology of these canals, together wit...

INTRODUCTION Gomphodonts are a clade of derived non-mammalian cynodonts characterized by the possession of transversely expanded postcanine teeth with crown-to-crown occlusion. These molar-like postcanines, characterized as ‘gomphodont’ teeth, are generally considered to be specialized for processing a predominantly herbivorous diet (Hopson 1971). If the contentious Tritylodontidae are omitted ...

BACKGROUND AND AIMS A perfect endodontic treatment necessitates proper understanding of the morphology of canal and pulpal variations. This in vitro study was conducted to demonstrate the in-ternal anatomy of mandibular canine teeth in an Iranian population. MATERIALS AND METHODS The samples consisted of 100 extracted mandibular permanent canines. The roots of the teeth were molded in acrylic...

INTRODUCTION To determine the morphologic shape and position of the root apex and the major foramen in maxillary and mandibular teeth. METHODS A total of 845 maxillary and mandibular human teeth root specimens were evaluated. Each root specimen was measured at each root apex by using a calibrated microscope at a magnification of 20x. The anatomic parameters evaluated included the position of ...

Worn teeth are a bane to paleobiologists interested in the diets of human ancestors and other fossil primates. Although worn teeth dominate fossil assemblages, their shapes are usually not used to reconstruct the diets of extinct species. The problem is that traditional studies of primate dental functional anatomy have focused on unworn morphology. This has limited most functional analyses to o...
