Trabecular pattern in the mandible as bone fracture predictor.

• OBJECTIVE: This investigation analyzed the use of mandibular sparse trabeculation as a fracture risk indicator. STUDY DESIGN: Trabeculation was classified as sparse, alternating dense and sparse, or dense using intraoral radiographs from 274 men and women (50-87 years old) including 56 with previous reported fractures. Mandibular bone texture was assessed on digitized radiographs. RESULTS: Forty-eight percent of subjects with sparse trabeculation reported fractures, compared with 19% with alternating sparse and dense trabeculation and 2% with dense trabeculation (Kruskal-Wallis test: P < .00001). Logistic regression analysis showed that sparse trabeculation (odds ratio [OR] = 5.9; 95% CI 3.0-11.1; P < .0001) and lowest bone texture classes (OR = 2.2; 95% CI 1.0-4.5; P = .04) were associated with an increased fracture risk, especially for subjects > or =75 years (OR = 7.1; 95% CI 2.5-20.0; P = .0002). CONCLUSIONS: Fracture risk was increased in subjects with sparse alveolar trabecular pattern. Dentists may be able to identify high-risk subjects before fracture.
