ABSTRACT

Aim: To evaluate the effect of low-level diode laser therapy on wound healing after gingivectomy.

Methods: Forty patients (male and female) with ages ranging from 20-40 years received gingivectomy participated in this study. They were selected randomly from dental outpatient clinic at Badr university in Cairo and randomly divided into 2 equal groups in number, one study group (A) and control one (B). The study group (A)was irradiated with Gallium Arsenide (GaAs) laser of wavelength 850 nm for 4 sessions on day 0, day 3, day 7 and day 14 post gingivectomy.The control group (B) who received placebo laser.Assessment of healing was done before starting the first session (day 0), day 7, day 14 (after session) and follow up assessment (day 21).The healing assessed by photographic method by applying image J software and Landry index.

Results: The results of this study support that the low-level diode laser therapy was significantly effective on wound healing in patients after gingivectomy. There was a highly significant difference between two groups after the treatment. Conclusion: It was concluded that the low-level diode laser therapy is an effective method for increasing wound healing after gingivectomy.
