Introduction: Increasing of age in adults is normally accompanied by some levels of decreasing in life quality, however, we cannot ignore the effect of other variables like tooth loss. Therefore, the present study was conducted aiming at determining the life quality in patients with denture, who referred to the prosthesis department of Yazd dental school in 2012. Methods: In this descriptive- analytical study, 117 patients who referred to the prosthesis department of Yazd dental school were chosen by the simple random sampling. The required data were collected by using a valid and reliable questionnaire. The data were analyzed by SPSS (ver.17) applying ANOVA, T-test and Pearson&#39;s correlation coefficient. Results: In the present study, 117 patients, aged 31-74, participated among which, 44 (37.6%) were males and 73 (62.3%) were females. The range of using denture was 1 to 5 years. The average score of life quality in all aspects revealed a statistical significance in regard with age and duration of using denture (P.value< 0.05). According to the results of Pearson test, all the aspects of life quality had a positive and significant relationship with each other. Conclusion: The study results revealed that the people who used denture less than the others had a higher score of life quality. Moreover, it was demonstrated that life quality decreases with increasing patients’ age.
