Aesthetic Crown Lengthening: Laser Impact on Pain Perception and Perceptions on Self-esteem and Quality of Life

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Periodontal health diagnosis (full mouth bleeding on probing - BP <10%, clinical attachment level - CAL ≤ 3mm),
Distance from the gingival margin to the cementum-enamel junction ≥ 3mm associated with a gingival smile and / or short clinical crowns when compared to anatomical crowns, due to the altered passive eruption or gingival overgrowth).
Good general health

Exclusion criteria

Presence of systemic changes (diabetes, heart disease, hepatitis, etc.)
Use of medications (such as antibiotics, continuous anti-inflammatory drugs, phenytoin, cyclosporine) that may influence the response to the surgical treatment
Diagnosis of gingivitis and/or periodontitis
Smoking habit
Pregnancy or lactation period

Treatment and study plan

Crown lengthening surgery

Procedure

Following clinical and radiographic examinations and thorough case planning, surgical procedures were performed under local anesthesia by a single operator. After anesthesia, the distance from the gingival margin to the cementoenamel junction will be measured, and these values will be transferred to the gingival tissue to guide the procedure. Excess gingival tissue will be excised, and, when necessary, an osteotomy will be performed to re-establish the supracrestal attachment tissues.

Primary outcomes

Patients' levels of self-esteem and quality of life

Time frame: 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.
