RESUMO

This study was performed to evaluate and compare the effect of Gallium Arsenide diode laser [Ga-As laser] as an adjunct to wound healing in experimental induced diabetes in rats. It was conducted on sixty adult albino rats, all animals had undergone excising small biopsy of the oral mucosa, and then thirty rats were subjected to low intensity laser therapy while the remaining thirty rats were used as diabetic control. Animals were sacrificed after one week and two weeks intervals and specimens were collected for microscopic as well as immunohistochemical evaluation. The correlation between different methods of assessment assured the findings of this study that laser treated animals showed accelerated healing compared to non-lased animals

RESUMO

Eighty [80] male albino rats were included in this study. The rats were divided into two groups. The first group [40 rats] subjected to scalpel surgery to excise a biopsy about 2 x 2 mm from the lower anterior labial vestibule. The second group [40 rats] received CO[2] laser in the same way at 6 watts in a focused mode with water irrigation. Ten animals from each group were sacrificed at weekly intervals from the date of beginning of surgery for 3 weeks. The biopsies were assessed histopathologically and immunohistochemically. The results were confirmed by the image analysis and statistical analysis. It has been found that CO[2] laser could be considered as an excellent surgical instrument and become an alternative modality in performing many of surgical procedures
