Objective: The purpose of this study was to evaluate the impact The impact of tooth loss on oral healthrelated quality of life among the elderly population in Seongju, Korea.Methods: A total of 517 participants (male 215, female 302) aged more than 65 years (mean 71.7years) were surveyed cross-sectional ly. The subjects were examined their oral conditions by 2 traineddentists, and also surveyed their socio-demographic characteristics and oral health related quality of lifeby face to face interviews. Dental examinations included the number of missing teeth, the number ofteeth with caries, and status and need of denture. Oral health related quality of life was evaluated byshort-fon-n of Oral Health Impact Profile (0HIP-14). The participants were divided by two groupsaccording to the number of tooth loss; (1) tooth 1oss< 9 and (2) tooth loss >9, respectively. Thedifferences in 0HIP-14 and it's 7 subscales between two groups were tested by student' s t-test. Theassociation between tooth loss and 0H1P-14 was assessed by multiple regression analysis afterResults: There was significantly difference in mean scores of0HIP-14 between the participants with< 9 tooth loss (63.60) and the participants with>9 tooth loss (61.62) (P=0.005). Among the 7 0HIP-14subscales, the mean scores of functional limitation, Physical disability and handicap were significantlyhigher in the participants with < 9 tooth loss than in those with > 9 tooth loss (P < 0.001, P=0.029, andp=0.006, respectively). No significant differences in the mean scores of physical pain, Psychologicaldiscomfort, psychological disability and social disability were founded by the number of tooth loss.Multiple regression analysis identified that the 0HIP-14 score of'an individual with U 9 tooth loss wastended to decrease compared with the score ofan individual with < 9 tooth loss after adjustment for age,gender, educational levelJob status, and income(b=-1.55, P=0.032).Conclusions: The findings of the present study indicated that old participants with < 9 tooth loss hadbetter oral health related quality oflife than those with >9 tooth loss.
