AIM The purpose of this study was to characterise the enamel surface of sound deciduous teeth in terms of morphology, chemical composition, structure and crystalline phases. MATERIALS AND METHODS The enamel of 30 human deciduous teeth was examined by: Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), X-ray Powder Diffraction (XRD), Fourier Transform Infrared Spec...

Postnatal dental development may be used as a reference standard in the absence of exact-age information because dental variability is less than variability for other calcified structures (S. M. GARN, A. B. LEWIS, and D. L. POLACHECK, Science 128:1510, 1958; J Dent Res 38: 135-148, 1959) and is not affected much by nutritional status (S. M. GARN, A. B. LEWIS and R. S. KEREWSKY, J Dent Res 44:22...

Cleidocranial dysplasia is an autosomal dominant condition caused by mutation of RUNX2, involving the skeleton and the teeth. It presents with a major finding of the hypoplasia or aplasia of clavicles along with late closure of the fontanels, presence of open skull sutures and multiple wormian bones. Although not frequent it can present to the dentist commonly with significant retention of mult...

Developmental anomalies can occur as a result of conjoining or twinning defects. These include fusion, gemination and concrescence. Such anomalies occur more often in the deciduous than in the permanent dentition and only a few cases involving molar and premolar teeth have been reported in the literature. Cases of bilateral double teeth are less frequent than unilateral and prevalence seems to ...

AIMS This retrospective study aimed to assess the prevalence of dental trauma in deciduous and permanent teeth among children and teenagers who attended two dental clinics in Targu Mures, Romania, between 2003 and 2011 and the correlation of their risk of dental trauma with factors, including gender, age, physical activities and extent of incisor overjet. METHODS The study population consiste...

Aims: To determine the prevalence, and severity of dental caries in school children of Tafeleh Governorate –South of Jordan aged 6-11 years and to evaluate the oral hygiene habits among them as a part of National Woman’s Health Care Center Survey. Methods: A cross-sectional census was conducted on 999 public school students aged 6-11 years (mixed dentition stage) living in 3 different parts of ...

Schwartz ('74) proposed revised homologies of the deciduous and permanent anterior teeth in living lemuriform primates of the family Indriidae. Gingerich ('77) described a juvenile specimen of Avahi and emphasized the importance of functional integrity in controlling the pattern of dental reduction in primates, neither of which supports Schwartz's interpretation. Schwartz ('78) recently reitera...
