• Lead Sponsor: University of Campinas, Brazil

Brief Summary

Gummy smile is a condition that promotes a disharmonious smile, altering confidence and decreasing self-esteem of many patients. Luckily, this problem in most cases is easily solved by aesthetic crown lengthening surgery. However, this is a surgery that is still considered by many patients to be painful and uncomfortable. Thereby, this study seeks both to evaluate possible changes in patients' self-esteem and self-confidence after the aesthetic crown lengthening surgery.

Detailed Description

Periodontally healthy patients who expressed interest in undergoing ACL will be selected. Before surgery, two questionnaires will be administered: the OHIP-14/Brazil and the Rosenberg Self-Esteem Scale-UNIFESP/EPM. These tools are designed to assess patients' perceptions of self-esteem and quality of life and will be re-administered 30 days and one year after surgery.

Primary Outcome Measures

Name	Time	Method
Patients' levels of self-esteem and quality of life	From enrollment through study completion, an average of 2 years	The perceptions of self-esteem and quality will be measured through the OHIP-14/Brazil and the Rosenberg/UNIFESP-EPM Self-Esteem Scale questionnaires.The Rosenberg questionnaire addresses an individual's overall sense of self-worth and self-acceptance, evaluating both positive and negative self-perception domains to provide a holistic view of their self-esteem. It consists of 10 statements rated on a 4-point Likert scale, with responses ranging from 'Strongly Agree' to 'Strongly Disagree.' Scores range from 0 to 30, where higher scores indicate greater self-esteem, while lower scores suggest diminished self-worth or a negative self-view. The OHIP-14 (Oral Health Impact Profile-14) questionnaire evaluates the impact of oral health on an individual's quality of life. It measures functional and psychological well-being across seven domains to assess how oral conditions affect daily life and overall well-being.
