The purpose of this study was to evaluate whether Low-Level Laser Therapy (LLLT) improves the healing of the implant surgical site with clinical and biochemical parameters.Thirty patients with an edentulous space spanning a single tooth were selected. The patients were randomly allocated to two groups - the control group and the test group. The test group received laser energy at a power of 2J/cm 2 with a total of 4-6J energy over each implant. Clinical parameters (Implant Stability Quotient, probing index, modified sulcus bleeding index)and osteoprotegerin (OPG) were assessed at baseline and follow-up intervals (2 weeks, 6 weeks, and 3 months).The test group showed significantly higher implant stability quotient compared to thecontrol group at 2 weeks(57.93±3.95 and 35.67±3.08; p<0.01) and 3months(58.86±3.75 and 67.06±3.78; p<0.01). A significant rise in OPG levels of the test group(686.30±125.36pg/ml at baseline and 784.25±108.30pg/ml at 3months;p<0.01) was seen contrary to significant decline in the control group (839.50±249.08pg/ml at baseline,415.30±78.39pg/ml at 3months;p<0.01). Within the limitations of the study, the study suggests that the healing of peri-implant hard and soft tissues may be enhanced with the use of LLLT as an explicit modality during the post-operative period.

Aim: The extrusion of sodium hypochlorite through the apical foramen is an accident that can occur during the endodontic treatment although is relatively uncommon, Due to the severe tissue damage that is caused by the solution, the management becomes important to prevent serious sequalae. Low-level laser therapy might be useful to treat damaged soft tissues because of its bio modulatory effects, which may reduce edema and prevent infection. Methods: In this clinical case, the accidental leakage of 5% sodium hypochlorite during the preparation of the root canal of an upper left canine is reported. The accident caused immediate and intense pain and severe edema and ecchymosis. The conventional treatment protocol was applied along with low-level laser therapy. Results: Clinical examination revealed the healing of soft tissue in thirteen days, besides a significant pain reduction in three days after laser therapy was applied. Conclusion: The combination of low-level laser therapy with a conventional treatment protocol could be a useful tool to manage such an accident.
