Aim: The aim of this clinical study was to evaluate the effect of low-level laser therapy, used in conjunction with conventional canal disinfection techniques, on post-operative pain after single- and multi-visit root canal treatments for chronic apical periodontitis. Methodology: 100 volunteers were randomly divided into 4 groups. The main inclusion criteria were radiographic evidence of apical periodontitis (minimum size of 2.0 × 2.0 mm) and a diagnosis of pulpal necrosis confirmed by a negative response to vitality tests. All the root canals were prepared using a standard shaping technique and irrigation procedure. In Groups I and III, the root canals were obturated during the first visit following chemo-mechanical preparation. In Groups II and IV, the root canals were medicated with calcium hydroxide and obturated during a second visit, 1 week later. In Groups III and IV, after the chemo-mechanical preparation, the root canals were additionally irradiated by an 810-nm diode laser at 1.5 W output for 20 seconds. A modified visual analogue scale was used to measure pain at 4, 8, 12, 24, and 48 hours and 7 days after the treatment. Results: There was no statistically significant difference between the groups in terms of post-operative pain at any time during the observation period (p > .05). Post-operative pain occurred only at 8 and 12 hours and at 1, 2, and 3 days in all groups. There was no correlation between the results regarding age, gender, periapical index scores, or tooth type. Conclusion: The use of low-level laser therapy had no significant effect on the incidence of post-operative pain, and single-visit root canal treatment may be a strong alternative to multi-visit treatment.

Gingival Graft

Introduction: Free gingival grafting is among the most foreseeing procedures for increasing the zone of keratinized attached gingiva and enhancing soft tissue around the teeth and dental implants. Nowadays low-level laser therapy (LLLT) is a promising approach in providing patients with more pleasing results in terms of esthetics and comfort. This study aims to investigate the effects of LLLT on gingival recessions treated with free gingival graft (FGG). Methods: This case series was conducted on 12 individuals requiring a bilateral gingival graft in the mandibular region. There was a 30-day interval between the two operations. The test side was selected randomly and irradiated by a low-level laser (LLL) just before surgery. The patients did not know which side was irradiated. LLLT was applied to the donors’ as well as recipients’ site immediately after the operation and 48 hours later. The patients were instructed to record their post-operative pain in a visual analogue scale (VAS) 3 and 24 hours and 7 days after the surgical procedure. The clinical photographs were taken immediately and 30 days after surgical treatment were graded by three experienced periodontists for color matching to adjacent tissues. Results: Ten individuals could finish the study. The test group presented significantly better shade matching and wound healing at the palatal donor site on days 7, 14 and 21. There was a significant reduction in post-operative pain after 24 hours (P=0.007). No statistically significant difference was found between both groups in terms of clinical periodontal indices. Conclusion: LLLT could reduce post-operative pain 24 hours after surgical treatment. Furthermore, the application of LLLT could improve the donors’ site healing and the recipients’ site color matching.

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.
