Purpose: The present study was conducted to evaluate the clinical, osteocalcine biomarker and radiographic effect of biomodulaion effect of low intensity laser as an adjunct to mechanical debridement in the treatment of chronic periodontitis.
Material and methods: This study was conducted on twelve (24) healthy patients that were randomly divided into two groups: Group A (control group) twelve (12) patients with one stage mechanical debridement without the use of the low intensity laser as an adjunctive treatment; Group B (Test group) twelve (12) patients with three stage treatment high level laser decontamination, mechanical debridement with the use of bio modulation six sessions of low intensity laser.
Results: Test group showed a significant increase in the clinical parameter, osteocalcin biomarker level after three and six months in comparison with control group after three and six months follow up. Conclusion: The use of high level laser decontamination, low intensity laser with conventional mechanical debridement showed an improvement in the treatment outcome of chronic periodontitis.
