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.

Study Groups

Crown lenghtening surgery associated with Laser therapy

After crown lenghtening surgery in aesthetic area, the laser will be applied on the "Right" or "Left" oral side (chosen randomly), in all the 20 patients, in a "Split-mouth" model.

Group Type: EXPERIMENTAL

Crown lengthening surgery

Intervention Type: 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.

Crown lenghtening surgery without Laser therapy

After crown lenghtening surgery in aesthetic area, all the 20 patients, will not receive laser treatment on an oral side.

Group Type: PLACEBO_COMPARATOR
