BACKGROUND Using photographs of occlusal surfaces instead of extracted teeth for the detection of caries can be useful in multicenter studies or education. Using a panel of observers, ICDAS scores on teeth or photographs were evaluated against the histological gold standard. The hypothesis was that both outcomes were equivalent. METHODS Four examiners with different experience in ICDAS scored...

Sixty intact, non-carious and unrestored teeth extracted due to periodontal disease were used to determine the most effective method of sterilisation. The teeth were divided into six groups, each containing 10 teeth. Group 1 teeth were immersed in 10% formalin for seven days, group 2 teeth were immersed in 3% hydrogen peroxide for seven days, group 3 teeth were immersed in 2.6% sodium hypochlor...

objective: in comparison to clinical oral health indices, perceived oral health measures are less applied in large-scale epidemiological oral health studies in iran. the aim of this study was to measure perceived oral health among adults in tehran, iran. methods: in this cross-sectional study, perceived oral health was measured in 1100 adults in tehran by two measures: 1- non-replaced extracted...

A survey was carried out to determine the reasons for extractions of teeth in the middle (central) region of Jordan. Data was obtained from 80 dentists practicing general dentistry over a period of 2 weeks of their practice. The results revealed that out of the 1030 teeth extracted, 39.7% were removed due to extensive caries, 20.9% due to periodontal diseases, 13.4% at the patient's request, 10...

AIM To detect and to visualize radiographically vertical root fractures in extracted teeth with a prototype of a novel, high resolution, three-dimensional flat panel volume detector computer tomograph (FD-VCT) system. SUMMARY Five teeth with root fillings and clinical symptoms such as fistulas and isolated periodontal pockets of 8 mm or more were extracted after dental radiography indicating ...

INTRODUCTION We aimed to compare apical canal transportation of extracted teeth and two types of simulated resin blocks. MATERIALS AND METHODS Mesiobuccal root of extracted maxillary molars, high hardness simulated resin blocks (Knoop hardness=40) and low hardness simulated resin blocks (Knoop hardness=22) were prepared with K-files using step-back technique (n=15 canals in each group). Doubl...

PURPOSE The purpose of this study was to evaluate histologically the effect of an enamel matrix derivative as a pulpotomy agent in primary canines. METHODS Ten carious primary canines among teeth deemed for serial extraction were selected for this study. Emdogain gel was used as the pulp dressing material on the amputated pulp stumps. Teeth were extracted postoperatively after: (1) 1 week; (2...
