OBJECTIVE Anatomical racial variations are an acknowledged characteristic in permanent molars. Generally, mandibular first molars have 2 roots; however, the presence of a third root, radix entomolaris (RE), is a major anatomic variant among many population groups. This study evaluated the prevalence of permanent mandibular first molars featuring a distolingual root in a South Indian population....

Information regarding the anatomy of the physiological apical foramen is limited. Knowing its diameter and shapes contributes to clinical work, specifically to the cleaning and shaping of the apical third. The aim of this ex vivo study was to determine the minimum and maximum diameters and shape of the physiological apical foramen in the roots of maxillary and mandibular first molars. A descrip...

OBJECTIVE This retrospective study was conducted to analyze changes in the maxillary permanent molars after monobloc advancement with rigid external distraction (RED). SETTING University hospital-based craniofacial center. MATERIALS AND METHODS Fourteen patients, three in primary, eight in mixed, and three in permanent dentition underwent monobloc advancement with RED. After a latency perio...

OBJECTIVES The assessment of bitewing radiographs requires knowledge of radiographic anatomy and pathology, and the comprehension of possible effects of superposition which may lead to false positive diagnoses. Based on a clinical case report in which non-carious radiolucencies were discovered on the mesial surfaces of upper molars, this phenomenon, which has not been reported before, was expla...

Third molar development was evaluated in 786 young people aged between 4 and 20 years, all patients at the School of Dentistry of the University of Granada. The development of third molars and of mandibular second premolars and second molars was determined according to the stages proposed by Nolla. The onset of mandibular third molar formation was observed at very variable ages in this series, ...

Enamel pearls are anatomical structures that can bring about clinical implications if associated with the retention of plaque, in turn resulting in periodontal disease. In an attempt to avoid periodontal disease, the removal and treatment of these enamel pearls, may be a necessity in some circumstances. A total of 45,785 extracted teeth from a human teeth bank were analyzed for the presence of ...

The objective of this study was to measure the effectiveness of fluoride varnish as a public health intervention to prevent caries on partially erupted first and second permanent molars among 6-11 year old children at high risk for caries. In a six-month clinical trial, 105 children were randomly divided into a fluoride varnish (Duraphat) group (117 molars) or a control group (117 molars). The ...

Analysis of breeding records suggests that the occurrence of fused and supernumerary molars in the rice rat, associated with lower body weight than normal and with reduced fertility, is dependent on a single autosomal recessive gene subject to background modification. Molar fusion, which is preceded by stripping of the external enamel epithelium from the interdental lamina, may involve the firs...

Objective: In this study, it was aimed to determine the age of onset crown calcification third molars in children aged 5-15 years Turkey, and evaluate development status by age.Material Methods: Panoramic radiographs first 1024 patients between ages 5 15 were evaluated. The (calcification) classified according Demirjian method.Results: When stages for maxillary mandibular compared, no statistic...

AIM To evaluate the anatomical features of C-shaped canal systems in Chinese mandibular second molars by cone-beam computed tomography (CBCT). METHODOLOGY A total of 608 patients of Chinese descent with healthy, well-developed mandibular second molars were enrolled. These patients were referred to the West China Hospital of Stomatology and required radiographic examination by CBCT as part of ...
