AIM: The aim of this study was to compare the effect of low level laser therapy (LLLT) with non-LLLT as an adjunct to mechanical debridement in patients who develop gingival inflammation during fixed orthodontic treatment. MATERIALS AND METHODS: Thirty subjects undergoing comprehensive fixed orthodontic treatment were randomly allocated. Split mouth design was applied for each patient, where the four quadrants were randomly allocated to receive full mouth debridement. The test group (quadrant) received three laser sessions (days 1, 3, and 5) besides debridement while the control group (quadrant) received debridement only. Both bleeding index (BI) and plaque index (PI) were measured after 1 and 3 months, while the total colony forming units (CFU) were measured after 2 and 6 weeks. RESULTS: Clinical assessments (BI and PI) showed a statistically significant decrease at the first follow-up (after 1 month) and a slight increase in the second (after 3 months) that did not reach the base line. While, the total CFU showed a significant decrease in both follow-ups. CONCLUSION: Laser showed superior results in the treatment of gingival inflammation induced by fixed orthodontic appliances other than debridement only.

Maximum Pain

Patients still refuse or discontinue orthodontic treatment due to related pain and discomfort. In this study, we investigate if low-level laser therapy (LLLT) can reduce pain caused by orthodontic bands. Sixty subjects who needed bands placed on the upper permanent first molars were assigned randomly to the LLLT group, placebo, and control groups. Inclusion criteria were: age range 10–14 years, fully erupted upper first molars in healthy condition, presence of tight mesial proximal contact. Exclusion criteria were: systemic or metabolic diseases, chronic pain or neurological or psychiatric disorders, use of pharmacological agents interfering with pain perception, previous orthodontic treatment or the simultaneous presence of other devices in the patient’s mouth. The assessment of pain was performed by using a numeric rating scale (NRS) considering different time intervals, i.e., immediately after bands placement, 6 h, 24 h, and from day 2 to day 5. Differences in the maximum pain and in pain experienced at each time-point, among the three groups, was assessed by using the Kruskal–Wallis H. The final sample included 56 patients, 29 males, and 27 females, with a mean age of 12.03 ± 1.3 years. Patients were randomly allocated into three groups (tested, control, and placebo group) with each group consisting respectively of 19, 20, and 17 individuals. Subjects in the LLLT experienced less pain at each time interval as well as the maximum pain score being lower in the LLLT compared to control and placebo groups. These findings were all statistically significant (p < 0.05). LLLT can alleviate the intensity of pain after the placement of orthodontic bands.

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&lt;0.01) and 3months(58.86±3.75 and 67.06±3.78; p&lt;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&lt;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&lt;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.

Introduction: according to scientific literature, does low-power laser promote acceleration of tooth movements during orthodontic treatment? Objective: to systematize the ability of the low-power laser to accelerate tooth movements during orthodontic treatment. Material and methods: a systematic review was carried out, a search using Boolean search engines on the PubMed platform. The keywords used for were: orthodontic movement, orthodontic tooth movement, orthodontic, orthodontic treatment, low level laser therapy, low level laser, laser therapy and the combination between them. The included investigations dealt with the issue of acceleration of tooth movement during orthodontic treatment using low-power laser, were from journals indexed in PubMed, clinical trials, in English, and corresponded to articles published since 2000 to date. Assessment of risk of bias was performed. The variables analyzed were: main author, title, year, type of article, journal, country of research, and whether the articles show that low-power laser increases tooth movement during orthodontic treatment. Results: 60% of the included studies conclude that the low-power laser accelerates tooth movement during orthodontic treatment, 30% of these did not find significant changes in relation to the groups studied with those of control and 10% resulted in dubious conclusions. Conclusions: although the results are encouraging due to the trend in which the low-power laser does accelerate orthodontic movements, the presence of a higher number of randomized clinical studies would be necessary for a specific clarification of the benefits that this therapy brings to the patient. sector.

Background: The most frequently performed surgical procedure in dentistry is impacted third molar extraction with difficulty varies according to the location of the tooth. Laser therapy after surgery can accelerate cell and tissue reconstruction along with relieve post-operative pain. The objective of this study was to investigate the clinical and radiographic characteristics of impacted lower third molar and to evaluate the results of surgical extraction of impacted lower third molar with post-surgical low-level laser therapy (LLLT). Subjects and Methods: Clinical and radiographic data from 90 patients (average age 28.13 ± 5.38) subjected to a surgical extraction of lower third molar were pooled and divided randomly into 3 groups: group 1 received LLLT immediately after surgery intraorally, group 2 treated with LLLT immediately after the extraction extraorally. Patients received routine management with nonactivated laser were inserted in the control group. Assessments of pain, swelling and trismus level were carried out at 24, 48 hours and on the 7th day after surgery. Results: Correlation of wisdom teeth to ramus and adjacent teeth mainly type II (88.9%), type III accounted for 11.1%. Relative depth of wisdom teeth in the bone mainly position B (81.1%), position C (18.9%). Correlation of wisdom teeth axis to adjacent teeth: horizontal (58.9%), mesioangular impactions (40%) and distoangular impaction (1.1%). There were statistically significant decreases in the level of pain, edema and interincisal opening between the laser-treated groups and the control group on the 1st and 2nd postoperative day. Conclusions: Intraoral and extraoral post-surgical low-level laser therapy treatment was useful in reducing swelling, pain and trismus compared to placebo group in impacted third molar surgery. Key words: Impacted lower third molar, low- level laser therapy
