Eligibility

Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: Individuals over 18 years old; gummy smile caused by altered passive eruption or by improper positioning of gingival zeniths in the anterior region of the maxilla or mandible; having at least six teeth affected by the gummy smile; probing bleeding index less than 10%

Exclusion criteria

Exclusion criteria: Individuals with indications for gingivectomy/plasty; etiologies of gingival alterations indicating this type of surgery; patients with drug-induced gingival enlargement; patients with aesthetic restorations; orthodontic appliance users; those presenting active periodontal disease; smokers; pregnant or lactating women; individuals allergic to the medications prescribed in the study; patients with systemic diseases that may interfere with healing or periodontal health (such as diabetes, blood dyscrasias, among others)

Design outcomes

Primary

MeasureTime frame
It is expected that, at the end of the study, the hemiarch to which low-level laser therapy was applied will show better results for tissue healing, as assessed by the Landry index (1988), with a score of excellent healing (score 5) compared to the hemiarch that was not exposed to laser therapy

Secondary

MeasureTime frame
It is expected that low-level laser therapy will be capable of reducing postoperative pain, measured through the Numeric Rating Scale, with a score between 0 and 1.
