Abstract

Objective.

The purpose of this study was to compare endodontically versus nonendodontically treated teeth with respect to clinical features, including patient age and gender and tooth types of vertical root fractures.

Study design.

A total of 315 consecutive cases of vertical root fracture occurring in 274 Chinese patients during a 13-year period were reviewed. Age and gender, as well as tooth type and root distribution of vertical root fractures, were presented and compared in endodontically versus nonendodontically treated teeth.

Results.

Most patients (87%) had 1 fractured tooth; the others had 2 or 3 fractured teeth. Of all vertical root fractures, 40% occurred in nonendodontically treated teeth. In comparison with those in endodontically treated teeth, vertical root fractures in nonendodontically treated teeth tended to occur in patients with a higher mean age (55 years vs 51 years) and were more frequent in male patients (78% vs 58%). Vertical root fractures occurred in nonendodontically treated teeth more often in molars (84% vs 53%), less often in premolars (16% vs 33%), and seldom in anteriors (1 tooth vs 27 teeth).

Conclusions.

Vertical root fractures in nonendodontically treated teeth are not uncommon and comprise a large proportion of such fractures in Chinese patients. Differences between endodontically and nonendodontically treated teeth in patient age and gender, as well as in tooth types of vertical root fractures, were demonstrated.
