Impact of Subepithelial Connective Tissue for Root Coverage on Brazilian Patients' Quality of Life: A Longitudinal Clinical Study.

Aims: Gingival recession has been associated with dentin hypersensitivity and aesthetic impairment. The impact of gingival recession and periodontal surgical procedures on adult patients' quality of life are scarce. The aim of this study was to evaluate the quality of life of patients submitted to root coverage procedures with subepithelial connective tissue grafts and coronally advanced flap.

Materials and methods: Patients were asked to use a numerical rating scale to classify their dentin hypersensitivity, aesthetics, pain/discomfort, chewing, and brushing abilities in gingival recession sites treated with subepithelial connective tissue grafts plus coronally advanced flap. The patients answered a self-administered questionnaire about quality of life-related to oral health (OHIP-14) after 7, 14, 30, 90, and 180 days. Descriptive statistics were used to synthesize the data recorded.

Results: Mean percentage of root coverage was positively related to OHIP-14 (dimension 2- physical pain) in 90 days postoperatively. The quality of life (OHIP-14 total score) significantly improved from baseline to 90 and 180 days postoperatively. The numerical rating score analysis revealed significant improvement in the chewing and brushing abilities when period of 7 days was compared to 90 and 180 days and from 14 to 180 days.

Conclusions: Root coverage procedures with subepithelial connective tissue grafts plus coronally advanced flap result in a positive effect on adult patients' quality of life.
