INTRODUCTION Our aim was to investigate 8 years of vertical changes of the gingival margin and tooth displacement of maxillary molars and incisors in adolescents and adults. METHODS Twenty-five adolescents and 10 adults were included in this study, with dental casts taken 2 and 10 years after orthodontic treatment. The gingival contour of the teeth was traced digitally using calibrated photog...

OBJECTIVES The purpose of this study was to examine the location and accessibility of the second mesibuccal canal in maxillary first molar of a Turkish sub-population. METHODS Presence and accessibility of the MB2 canal in 110 extracted maxillary first molars was examined with unaided vision, dental loups and the DOM. To characterize the geometrical location of MB2 canals, photographs of pulp...

The (calcification) classified according Demirjian method.Results: When stages for maxillary mandibular compared, no statistic...

AJXHOUGH the importance of Carabelli's cusp in phylogenetic studies and for primary racial classification is generally acknowledged, the exact significance of this variable trait remains obscure.and controversial (MOORREES, 1957; KORENHOF, 1960). In this report we examine the " progressive " versus " regressive " aspect of the controversy on which opinions have remained sharply divided for almo...

Objective: To determine the chronological eruption parameters of primary teeth in Indian children. Study Design: A longitudinal study consisting of 135 healthy children (74 boys and 61 girls) attending three child health centres in the city of Hyderabad, India were randomly selected and followed from the emergence of the first to the last tooth. Ages and order of tooth eruption were studied for...

PURPOSE The purpose of this study was to identify the most caries-susceptible site of pits and fissures on first permanent molars by quantitative evaluation of the mineralization in both caries-active and caries-free children, and to provide helpful information for cost-effective, targeted prevention. METHODS Eighty-four caries-free and 85 caries-active children were selected from 800 6- to 7...

INTRODUCTION The aim of this study was to evaluate the treatment effects of the First Class Appliance (FCA) (Leone, Firenze, Italy) used for the distalization of maxillary first molars in patients with Class II malocclusion and mixed dentition. METHODS According to the results of the power analysis for sample size calculation, 32 consecutive patients with bilateral Class II molar relationship...

Background Numerous researches have been done on the permanent maxillary first molars for the presence of an extra canal, especially the mesiobuccal roots for the presence of MB2 canals. Cone beam computed tomography (CBCT) has been used recently in the detection of these canals. However, literature discussing the efficacy and reliability of CBCT in the detection of these canals is scanty. Ai...

Taurodontism can be defined as a change in tooth shape caused by the failure of the Hertwig's epithelial sheath diaphragm to invaginate at the proper horizontal level. An enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cementoenamel junction are the characteristic features. Permanent molars are most commonly affected. Endodontic treatment ...
