Clinical assessment of low level laser (GaAlAs)‎ on gingivectomy wound healing

Abstract EN

Low-intensity laser therapy aims to suppression of pain, edema reduction and acceleration of wound healing.

The main aim of this study is to clinically evaluate the effects of Aluminum Gallium Arsenate laser 670nm in wound healing after gingivoectomy in 11 patients.

Surgery was performed in anterior upper and / or lower regions.

The right side of the patient (test group) received a laser energy density of 4J / cm², in a 48-hour interval, during one week, totalizing four sessions.

The irradiation was punctual in a contact mode in three points.

The left side did not receive irradiation (control group).

Clinical evaluation was performed by naked eye inspection by five observers, that they do not know the irradiated side, through photography of the treated areas at post-surgical periods of 7, 15, 21, 30, 60 days.

The best healed side was observed.

The Sign test was used for statistical analysis with a confidence level of 5 % (P < 0.05).

The examiners found a better pattern of healing sometimes in the test and sometimes in the control group until 21 days after surgery.

After this period there was no apparent difference between them.

There was no statistical difference between the sides (p > 0.05).

These results have shown that low-intensity laser therapy did not accelerate oral mucosa healing after gingivectomy.
