The aim of this study was to evaluate the risk of root resorption during orthodontic treatment of patients with aplasia, and to analyse the relative importance of some anamnestic and treatment variables. The subjects comprised 68 orthodontically treated patients with 1-16 congenitally missing teeth. The age of the patients was 11-20 years (mean 15 years). All patients were treated with fixed ed...

Although endodontic treatment is widely recommended for compromised dental pulp, there is no information regarding the factors associated with failures in primary teeth. The aim of this study was to evaluate the survival and factors associated with failure of pulpectomies performed in primary teeth by dental students. The sample comprised patients treated at a University Dental Service and requ...

AIM The purpose of this study was to evaluate the effect of smear layer on apical seal of endodontically treated teeth. MATERIALS AND METHODS Sixty freshly extracted human maxillary central incisor teeth were selected and were randomly divided into two experimental groups. Group A of 25 teeth and group B of 25 teeth and a control group of 10 teeth. Cleaning and shaping of the root canals were...

introduction : there is a direct relationship between the quality of root canal obturation and success of endodontic therapy. the aim of the present study was to assess the quality of canal obturation performed by undergraduate dental students at the faculty of dentistry, mashhad university of medical sciences, mashhad, iran. materials and methods: records of 200 endodontically treated teeth fr...

PURPOSE The aim of this study was to compare all ceramic inlay/onlay survival rates in vital and nonvital teeth having the same cavity design. Filling the pulp chamber with ceramic materials or not was also discussed. MATERIALS AND METHODS Ceramic class II inlays/onlays were made on 11 premolars and 30 molars: 14 vital, 27 endodontically treated. The same tooth preparation design was performe...

A prospective in vivo investigation was conducted to determine radiographic and clinical factors associated with contemporary nonsurgical endodontic retreatments. Approximately 1,100 failing endodontically treated teeth were screened to determine an appropriate treatment plan. Using magnification, 337 consecutive retreatment cases were evaluated and treated. The vast majority of the retreated c...

Nonhealing periradicular pathosis associated with endodontically treated teeth is customarily managed by revision (retreatment). Root-end resection is less often the first choice of treatment. Objectives. This prospective randomized study compared the outcome of retreatment and surgical intervention in root cana[ treated teeth with nonhealing periradicular pathosis. Study design. One such tooth...

The success of pulpotomy of young permanent teeth depends on the proper selection of dressing materials. This study aimed to evaluate the histological and histomorphometric response of dentin-pulp complex to the enamel matrix derivative (Emdogain(®) gel) compared to that of calcium hydroxide when used as a pulp dressing in immature young permanent dogs' teeth. Dentin-like tissues bridging the f...
