Clinical Trial Summary

The goal of this clinical trial is to compare the effects of photobiomodulation with red laser on gingival graft donor areas of the palate in comparison to only protection with wound dressing. The main questions it aims to answer are: Does photobiomodulation on the palate promote faster somatosensory recovery? Does photobiomodulation reduce pain in palate donor sites, improving the quality of life? Participants who need gingival graft surgeries will receive laser irradiation on the palate donor area or just protection with wound dressing. Data will be collected up to 60 days. Researchers will compare protection on the palate and protection plus laser irradiation to see if laser therapy may reduce pain and accelerate somatosensory normalization. Moreover, they will measure changes in the quality of life after treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Somatosensory recovery	Mechanical and pain detection threshold measured with Von Frey filaments	30 and 60 days postoperatively
Secondary	Assessment of Pain	Numeric analogue scale from zero to ten. Patients marks zero for no pain and ten for the worse pain.	24 hours, 3 days, 7 days and 14 days
Secondary	Measurement of Quality of life	Patients fill the Oral Health Impact Profile (OHIP-14) questionnaire. It comprises 14 questions about oral health problems. In each question the patient may answer if they he have those problems very often (coded 4), fairly often (coded 3), occasionally (coded 2), hardly ever (coded 1) or never (coded 0). Questionnaire scale ranges from 0 to 56 with higher scores indicating poorer quality of life.	Baseline, 7 days and 14 days postoperatively
