Procedures which produce bacteremias may lead to bacterial endocarditis in the susceptible patient. Recent work has suggested that bacteremia does not occur in children following extraction of teeth as it does in adults. One hundred and seven children were divided into four groups. Group I, which consisted of children who had nondiseased primary teeth extracted, had 35% positive blood cultures....

Dental biometrics used in forensic science for human identification. It utilizes dental radiographs. This radiograph provides information related to teeth shape, teeth contour and relative position of neighboring teeth, also it gives shapes of dental work like crowns, filling & bridges etc. This paper includes different method used for dental biometrics and related information. Dental biometric...

background: knowledge about root canal morphology and its frequent variations can exert considerable influence on the success of endodontic treatment. the aim of this study was to survey the root canal morphology of mandibular first premolar teeth in a gujarati population by decalcification and clearing technique.     methods: one hundred thirty eight extracted mandibular first premolar teeth w...

119 Abstract: The aim of this study was to investigate plaque formation on natural tooth surfaces by a replica technique, which offers investigation of oral hard tissue surfaces by scanning electron microscopy. This method is recommended in cases where direct investigation is impossible such as when nonextracted teeth are investigated or when extracted teeth are expected to be influenced by the...

Measurement of tooth lengths was carried out on 537 extracted human teeth. The teeth were collected from adults aged 17 years and above and preserved in formalin. The tooth lengths were obtained by taking measurements off calibrated graph paper. The lengths obtained in this study were comparable to previous data reported in the literature. However, this new data will provide useful guidelines i...

Introduction Tooth loss remains a significant health problem even in developed countries such as the United States. Our research focuses on the development of non-synthetic, bioengineered materials for dental and craniofacial tissue engineering. We hypothesize that dental stem cells harvested from extracted teeth provides a potential source for human progenitor cells for tissue engineering. Our...

OBJECTIVES The aim of this study was to evaluate the fracture resistance of endodontically treated teeth filled with a resin-based obturation material using two different chelating agents. METHODS AND MATERIALS Forty extracted single-canal human teeth were prepared, instrumented, and randomly divided into three groups: Group 1 (n=15) received a final flush with 10 ml of neutralized 17% EDTA, ...

introduction: all instrumentation techniques have been reported to be associated with extrusion of infected debris. the aim of this study was to evaluate the number of bacteria extruded apically from extracted teeth ex vivo after canal instrumentation using the two engine-driven techniques utilizing nickel-titanium instruments (flex master and mtwo). materials and methods: seventy extracted max...

Root caries was once considered a disease for which the elderly population had their teeth extracted and replaced with removable prosthesis. [1] Approximately 38% of patients between the ages of 55 and 64 years have root caries , and 47% of those between 65 and 74 years have experienced root caries. [2] At present ,root caries is becoming a new area of focused research in dentistry ,as more peo...

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...
