Determinants of Loss of Permanent Teeth. Final Report for Phase 2

摘要

Tooth loss remains an important problem. Caries and periodontal diseases areacknowledged to be the predominant pathological conditions associated with tooth loss. Previous studies indicate that a significant percentage of extracted teeth are restorable (many are moderate cost), suggesting that factors other than the clinical conditions of teeth are important co-determinants of tooth loss. The study's goal was to develop and implement a protocol whose objectives were: (1) to measure permanent tooth loss and its determinants (biological conditions of teeth, oral health status, sociodemographic and economic characteristics, attitudes and beliefs, preventive behaviors and prior utilization); (2) to develop a comprehensive model of permanent tooth loss, and (3) to assess the significance of factors contributing to permanent tooth loss. In Phase I, information is presented regarding the characteristics of patients and their extractions. In Phase II, similar information on patient characteristics is provided on five alternatives to extraction.
