Methods: Twenty rats were divided into 2 groups: Group C (control) and Group LLLT. A 5 mm diameter CSD was created in the calvarium of each animal. In Group C, the defect was filled by blood clot only. In Group LLLT, the defect received laser irradiation, it was filled with blood clot and then it was irradiated again. All animals were euthanized 30 days postoperative. Histometric, using image analysis software, and histologic analyses were performed. Amount of newly formed bone was calculated as a percentage of the total area of the original defect. Percentage data were transformed into arccosine for statistical analysis (ANOVA one way, Tukey, p<0.05).
Results: No defect completely regenerated with bone. Group LLLT (17.27% ± 6.96%) had statistically greater amount of bone formation than Group C (12.74% ± 4.53%).
Conclusions: LLLT significantly enhanced bone healing in surgically created CSD in rat calvaria.
