In peri-implantitis, treatment lasers are effectively used to enhance implant surfaces’ decontamination of bacteria. The type of lasers commonly used and tested in dentistry are Nd:YAG, Er:YAG and diodes. The Er:YAG laser is considered to be effective in removing biofilm from implant surfaces. Photodynamic therapy (PDT), realized with low-level laser therapy (LLLT) and a photosensitizer, seems to have limited efficacy in peri-implantitis management, while diode lasers used with high frequency and power (Wiser, Doctor Smile), performed with hydrogen peroxide 10 vol. 3% (OHLLT), seems to lead to a deep sanitization of implant surfaces, without any thermal effect. The aim of our retrospective controlled study is to compare an oxygen high-level laser therapy (OHLLT) protocol with OHLLT with an Er:YAG laser (Pluser, Doctor Smile) in order to maximize bacterial removal and to evaluate if an Er:YAG laser could improve hard tissue regeneration with respect to OHLLT alone. Two hundred and ten implants affected by peri-implantitis were divided into two groups: 88 implants were treated with OHLLT alone (control group) while 122 underwent OHLLT and Er:YAG treatment (test group). Mean bone loss before (T0) and after treatment (T1) (with a follow-up of 5 years) was registered for all implants. The collected data were analyzed with the Statistical Package for Social Sciences (SPSS) version 11.5. No statistically significant differences were found. In the OHLLT group, we noticed a mean bone loss after treatment of 2.1 mm in the upper arch and 2.4 mm in the mandible. In the OHLLT + Er:YAG group, the results indicate a mean bone loss of 2.0 mm in the upper arch and 2.5 mm in the mandible. Both groups showed a mean bone loss after treatment of 2.3 mm. According to the Kolmogorov–Smirnov test, overall, data followed a normal distribution (value of the K-S test statistic = 0.0912; p = 0.36112). OHLLT plays a central role in enhancing clinical results in peri-implantitis treatment, leading to an effective bacterial decontamination. Our results showed no statistically significant differences between OHLLT and OHLLT + Er:YAG laser; thus, the potential advantageous role of Er:YAG has been downgraded with the analysis of our study.

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.

Abstract INTRODUCTION: As conventional treatments currently available for mucositis are not considerably effective,there is a need to implement an adjuvant protocol for the treatment of oral mucositis in patients undergoing radiotherapy and chemotherapy.PURPOSE: To evaluate the effect of Low Level Laser Therapy and Antimicrobial Photodynamic Therapy mediated by curcumin and blue LED as an adjunct treatment of oral mucositis foroncology patients using chemotherapy and or radiotherapy.METHODS: Clinical, randomized study, in a single location, in an oncology service of a general hospital, with a total of 30 patients (over 18 years old) with stable oral mucosa lesions in the process of Chemotherapy and or Radiotherapy. The patients were divided into 3 groups: Control group (treated with nystatin), LLLT group (treated with Low Level Laser Therapy), and the aPDT group (treated with 450 nm blue LED and curcumin photosensitizer).RESULTS: The results showed, by means of intra-group comparisons, that the two experimental treatments promoted yeast reduction of the genus Candida in the last two evaluations (21 days and 30 days), but not in the first two evaluations (7 days and 14 days). The intra-group comparisons showed that the Control and aPDT group showed a significant difference in the degree of mucositis over the four evaluations performed, with the results pointing out that the mucositis worsened in the control group from the 14th day, while reduced in the aPDT group from the 21st day of treatment.CONCLUSION: A reduction in the degree of mucositis and pain score was observed in the LLLT and aPDT groups, with the aPDT group standing out when presenting early clinical improvement in relation to the LLLT group and the control group, thus emphasizing its effectiveness within the desired aspects. Regarding the antimicrobial effect, aPDT showed a greater reduction of yeasts of the genus Candida in the tested parameters.

Hospitalised Patients

Objective: A pressure ulcer (PU) is an area of tissue trauma caused by continuous and prolonged pressure, often associated with hospitalised patients immobilised due to neurological problems, negatively affecting their quality of life, and burdening the public budget. The aim of this study was to report the follow-up, for 45 weeks, of three patients with neurological lesions due to trauma who subsequently developed PUs, and who were treated with a combination of photodynamic therapy (PDT), low level laser therapy (LLLT) and cellulose membrane (CM). Method: PDT was mediated by the photosensitiser curcumin on a 1.5% emulsion base. Blue LED light at 450 nm was delivered continuously for 12 minutes at an irradiance of 30mW/cm2 and total energy delivered to the tissue was 22J/cm2. LLLT was performed with 660 nm laser, punctuated and continuous, twice a week with parameters: spot size 0.04cm2, power of 40mW, 10 seconds per point, fluence of 10J/cm2 and irradiance of 1000mW/cm2. Results: All PUs had a significant reduction (range: 95.2–100%) of their area after 45 weeks of follow-up and two PUs had complete healing at 20 weeks and 30 weeks. All of the PUs showed a reduction in contamination with the PDT treatments in different proportions. Conclusion: From the results obtained, we conclude that the combination of PDT, LLLT and CM is a promising treatment for PU healing.
