Abstract

Background: Maintenance of oral health status after dental treatment is essential to raise the patient's quality of life by being treated in a comprehensive program because multitasking work solves all the patient's dental problems. However, there is a possibility the treated tooth could be lost due to various factors, either patient related or tooth related factors. Knowing the risk factors is the best path to devise the most appropriate treatment plan. Objectives: To investigate the rate of tooth loss and determine the factors associated with tooth loss after comprehensive treatment. Method: Six hundred and seventy-six teeth from 38 patients treated in a comprehensive dental clinic and continuously monitored for at least 5 years were the representative sample to be studied about the rate of tooth loss and associated factors. Result: Eighty-five teeth (12.52%) were lost, and the rate of annual tooth loss was 0.32. When all the data were analyzed, there were consistent factors associated with tooth loss significantly (p < .05) including level of program compliance: erratic and non-compliance (irregular compliance) (OR 15.78, 95%CI: 3.76, 66.19), C/R ratio: C/R ratio 1-1.5 (OR 4.97, 95%CI: 2.96, 8.33), C/R ratio > 1.5 (OR 4.25, 95%CI: 1.52, 11.90) and type of retainer: direct retainer (OR 2.59, 95%CI: 1.45, 4.62), indirect retainer (OR 3.78, 95%CI:1.97, 7.27) Conclusion: The rate of tooth loss during the maintenance phase of in patients treated with a comprehensive program was 12.52%, rate of annual tooth loss: 0.32. The significant risk factors were irregular program compliance, crown/root ratio ≥ 1, and selected teeth as abutment (retainer)
