AIM To assess the survival rate of root filled cracked teeth over a 2-year period in a tertiary institute. METHODOLOGY Forty-nine patients who had root canal treatment completed on their cracked teeth at the National Dental Centre (Singapore) were recalled for a 2-year review. Collected review data included presence of periodontal pocketing, sinus tract and swelling associated with the teeth....

T echniques to reinforce endodontically treated teeth have been available for more than 100 years. However, few dentists have questioned the rationale that dictates automatic dowel reinforcement and coronal coverage of pulpless teeth. The difficulties of in vivo studies have motivated investigators to increase the number of in vitro studies of endodontically treated teeth. Although findings fro...

Fractures in the jaw bones could present themselves differently according to the strength of the force and the bone's ability to absorb the impact. The location and type of the fracture is important as well as the cause of the fracture (traffic accidents, melee trauma, pathologic changes). Pre-existing pathologic lesions, position of the teeth and the way they are affected by the fracture have ...

BACKGROUND An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence ...

Introduction: Intraradicular retention and stability in severely compromised anterior teeth, is an important factor for functional reconstruction of such teeth. Most commonly used posts are custom or prefabricated. the prefabricated posts include glass fiber, carbon fiber, metal or ceramics. However, till date none of the available posts meet all the biological requirements. this study is a bio...

The purpose of this study was to assess the histological appearance of the pulp of human primary incisors extracted because of deep, unrestorable caries, and to determine how clinical pulp exposures affected the histological status of the pulp compared to nonexposures. Caries was removed carefully from all teeth after fixation; 24 incisors had pulp exposures, and 29 teeth had no pulp exposures....

The purpose of this study was to find out the types of pathologies that can arise in association with impacted wisdom teeth. Two hundred consecutive patients scheduled for extraction of one or more of their impacted wisdom teeth were evaluated clinically and radiographically. Orthopantogram (OPG) was the standard radiograph. 194 (97 %) of the teeth were associated with pathologies. Pericoroniti...

A study of 150 extracted maxillary first premolars from citizens of Seville, Andalusía, southern Spain, revealed 60 teeth with one root (40.0%), 85 teeth with two roots (56.7%) and five teeth with three roots (3.3%). The distribution of root canal shapes in the sample showed that all teeth with two or three roots had type I root canals (each canal had one apical foramen). Conversely, most of th...
