The periodontal clinical measures of the effects of surgical and non-surgical techniques have been widely described, but the subjective parameters after the procedures need to be well investigated, focusing their direct influence on the quality of life of these individuals. This observational study aims to evaluate the impact of periodontal disease on the quality of life of individuals submitted to surgical and non-surgical periodontal treatment through the application of the OHIP-14 questionnaire. Sixty patients were interviewed, of which 30 were from the surgical treatment group and 30 were from the non-surgical treatment group. The subjects included in the study underwent surgical periodontal treatment with flap for access to scaling and non-surgical periodontal treatment with scaling and root straightening. The OHIP-14 questionnaire was applied at two times, 7 days and 30 days after treatment. The results of the surgical periodontal treatment group after 7 days showed a significant impact on quality of life, after 30 days did not show improvement in the quality of life, affecting the subgroup, and the results of non-surgical periodontal treatment after 7 days showed a small impact in quality of life after 30 days revealed an increase in quality of life. We concluded that the surgical periodontal treatment did not show benefits to the quality of life of the individuals, affecting more subgroup already the non-surgical periodontal treatment showed significant improvement in the quality of life of the individuals included in this study. Being the non-surgical treatment, the periodontal treatment of first choice more indicated and with greater chances of success.
