introduction: comparison of the relationships and distance between maxillary root tips and the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. methods: oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitat...
Background and Aim: The third molar tooth lies with symptoms such as periodontal problems, caries, crowding, root resorption, cyst and tumor formation of the adjacent second molar. The purpose of this study was performed to evaluation of the position of mandibular third molar teeth and its effect on second adjacent molar teeth. Materials and Methods: Panoramic radiography were obtained from 26...
Introduction: Complex molecular pathways involve in development of different tissues such as teeth. Differential gene expression patterns during teeth development generates different tooth types. Teeth development results from interactions between oral epithelium and underlying ectomesenchyme cells with neural crest origin. Teeth development are regulated by different signaling networks. In thi...
BACKGROUND Molar bonding procedures need continuous improvement to be widely accepted clinically and eventually replace molar bands. MATERIAL AND METHODS The purpose of this study was to determine the effects of enamel micro-abrasion and silane coating of the base of molar tubes on shear and tensile bond strengths of orthodontic molar tubes. A total of 200 third molars were randomly allocated...
objective: loss of tooth structure due to dental caries and cavity preparation can reduce fracture resistance, especially in endodontically treated teeth. the aim of the present study was to evaluate fracture resistance of pulpotomized primary molar teeth restored with extensive multisurface amalgam restorations. materials and methods: eighty extracted carious human primary molar teeth were sel...
introdouction: age estimation is an important issue in forensics, particularly for treatment planning and determining patients’ rights. radiographic evaluation of the third molar developmental stage is a significant criterion for age estimation. the pattern of tooth development is largely heritable and varies from race to race. the objective of this study was to radiographically examine and com...
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...
Aim: To determine the intensity of the impacted third molar and its clinical correlation. Objective: This study was done to check the impacted third molar and to study its clinical correlation. Background: A wisdom tooth or third molar is one of the three molars per quadrant of the human dentition.Wisdom teeth generally erupt between the ages of 17 and 25.Wisdom teeth commonly affect other teet...
The study investigates the gender predictability of permanent maxillary first molar teeth. Mesio distal width of 30 permanent maxillary first molar teeth from casts of 15 male and 15 female patients between the age group of 1725 were measured. Results showed that permanent maxillary first molar tooth exhibited sexual dimorphism but accuracy of gender predictability was only moderate.
AIM This was to evaluate the effect of different thicknesses of cavity walls on fracture strength of pulpotomized primary molar teeth with class II amalgam restorations. METHODS 80 carious extracted human primary molar teeth were selected for pulpotomy preparation. The teeth were divided into four groups. Mesio- or disto-occlusal (20 teeth) and mesio-occluso-distal (20 teeth); cavities were p...
