Incompletely fractured teeth--a survey of endodontists.

By means of questionnaires, 303 endodontists were asked about their experiences in the diagnosis and treatment of incompletely fractured teeth. The present article discloses the results relative to which teeth are most likely to fracture, which predisposing factors involve higher or lower risk, how endodontists prefer to treat root-fractured teeth, and the success rate they have had with them. The endodontists also reported the frequency of endodontic treatment failures attributable to root fractures. These results are discussed with respect to the potential implications for clinical dental practice.

Fractures of posterior teeth in adults.

Examined in this study were 191 patients with 206 complete or incomplete fractures of posterior teeth. The patients ranged in age from 14 to 76 years, with 66.5% younger than 40 years. The number of fractures occurring in each arch was almost equal. The mandibular first molar was the most frequently fractured posterior tooth. The lingual cusps of mandibular molars fractured more often than did the buccal cusps of mandibular molars by a ratio of 2 to 1. In maxillary molars, buccal and lingual cusps fractured with almost equal frequency, but, in maxillary premolars, the lingual cusps fractured slightly more often than buccal cusps. Data gathered on the widths of the isthmuses of restorations in 109 teeth showed that fewer fractures occurred in teeth with more conservative restorations, with widths of isthmuses a quarter of the inter-cusp distance, and intact marginal ridges.

Fracture resistance of human teeth with mesial-occlusal-distal cavities prepared with sharp and round internal line forms.

Conservative MOD amalgam-type preparations of similar dimensions were cut in extracted contralateral maxillary first premolars; one preparation for each pair had sharp internal line angles and the other had a rounded internal form. The data do not demonstrate a statistically significant difference in resistance to fracture between the two groups. The difference in preparation produced by the use of a flat-end bur vs. a rounded-end bur does not appear to produce a great enough concentration of stress to significantly weaken teeth with conservative preparations.

Potential for tooth fracture in restorative dentistry.

Increasing awareness of tooth fracture, both complete and incomplete, as a significant disease entity has led to improved diagnostic techniques. By using compact, easily handled, fiber optic instruments for transillumination and by developing a "predisposition index" to assist in the evaluation of fracture potential, new dimensions have been added in treatment planning, especially for older patients. Prevention of tooth fracture can best be accomplished by utilizing conservative, nontraumatic tooth preparation procedures, understanding predisposing factors, and using full occlusal coverage, circumferentially retained restorations whenever castings are indicated. Effective management of incomplete tooth fracture involves early recognition of the problem, appropriate and timely treatment, and a realistic assessment of the prognosis.
