Abstract
Introduction: One of the most important issues after gingivectomy procedures is to shorten the wound healing period and decrease pain. One of the new techniques is the application of low-level laser, which has attracted attention because of the absence of side effects, appropriate equipment, and low treatment costs. This study aimed to evaluate the effect of low-level laser on accelerating the healing process after gingivectomy.
Materials & Methods: Twenty-two samples in 12 patients with gingival hyperplasia on their symmetrical teeth were included in this controlled clinical trial. After gingivectomy, 660-nm low-level laser was randomly applied to one side for 5 days. The contralateral side served as a control with no laser irradiation. The surgical areas were subjected to a plaque-disclosing solution (Mira-2-tone) to visualize the epithelium in the surgical area. Comparison of the surface areas between the LLLT-applied and control sites were made with Photoshop software after taking photographs. Data were analyzed with paired-sample t-test, independent-sample t-test, and ANOVA using SPSS 23. Statistical significance was defined at p value < 0.05.
Results: There were no statistically differences between the stained surface areas of the LLLT-applied and control sites immediately after surgery and three days after surgery. However, the LLLT-applied sites exhibited significantly lower stained areas compared with the controls on the seventh and 15th postoperative days (p value < 0.001).
Conclusion: The results indicated that LLLT might enhance epithelialization and improve wound healing after gingivectomy.
Key words: Low-level laser therapy, Wound healing, Gingivectomy.
