Coronal fractures of endodontically treated posterior teeth in an Iraqi group

ABSTRACT

Coronal fractures of endodontically treated posterior teeth has been a common problem in clinical practice. Three hundred and eight fractured premolar and molar teeth in Iraqi patients were observed in this study. Many factors such as sex and age of the patient type of tooth, location of fracture and the distance of fracture-and from the gingival crest were recorded and statistically analyzed. The results of this study indicated that sex and age had no influence on the frequency of fractures. Premolars had a significantly higher number of fractures than molars. Lingual cusps fractured more than buccal cusps. Fractures ended more frequently below the.gingival crest Conservative access to root canals during endodotnic treatment and protection of the cusps specially in premolars are necessary against future fractures of such teet
