Abstract

Objective: The present study was conducted to provide immune-histochemical and histomorphometric analysis of early phase of wound healing following low energy erbium YAG laser assisted pocked debridement compared to conventional hand instrumentation scrutinizing the inflammatory cells and healing picture within initial phase. Material and method: 15 patients were selected with chronic periodontitis and attachment lost 5 mm on one aspect of the tooth. The active treatment consists of initial therapy- “closed debridement” conventional vs. laser assisted, using energy density of about 178 mJ/ mm2 for soft tissue and 256 mJ/ mm2 for scaling and root planning . The tissue biopsy was taken 24 and 72 hour after preformed periodontal treatment and following parameters were assessed: myeloperoxidase, CD68, vimentin and CD34. Results: The obtained result forhand instruments treated group versus laser treated group after 24h shows significant differences (p<0,001) on all parameters. Very similar results were obtained for hand instruments treated group versus laser treated group after 72h; significant difference between two groups (p<0,001) were obtained with higher CD34 expression for laser treated group. Conclusion: Obtained results showed relatively low postoperative cellular inflammatory response for myeloperoxidase, CD68, vimentin and higher CD34 expression most likely attributed to the minimally invasive pocket instrumentation and very narrow soft tissue zone of thermal disruption which could be interpreted as a positive signal insuring directs of appropriate cell types to area of inflammation in temporally correct manner.
