Efficacy of photobiomodulation therapy in recurrent herpes labialis management: a randomized controlled trial.

OBJECTIVES: This study is aimed at assessing the therapeutic efficacy of photobiomodulation therapy (PBMT) for the management of recurrent herpes labialis (RHL) by evaluating both pain and clinical recovery. MATERIAL AND METHODS: A randomized, double-blind, controlled trial was conducted on 40 patients with RHL, and they were randomly divided into two groups, where 20 patients received treatment with PBMT (650 nm, 100 mW, 4.7 J/cm2), continuous mode, for 120 s, and placebo cream, while another 20 patients (control group) were treated with acyclovir cream 5% (5 times/5 days) and passive laser. Pain was assessed at five different times. The day when the complete disappearance of the pain was observed and the day when the crust fell off spontaneously were also recorded. RESULTS: The pain level in the control group was significantly higher than that in the PBMT group after the second application of the laser, while the differences were not significant between the two groups at other times. The pain in the PBMT group disappeared faster than that in the control group, but the difference was not significant in terms of clinical recovery. CONCLUSIONS: Photobiomodulation therapy of herpes labialis reduced pain significantly faster than acyclovir, but there was no difference in healing time between the groups in light of the parameters used in this study. CLINICAL RELEVANCE: PBMT is a promising treatment that may be an effective alternative to acyclovir in the management of recurrent herpes labialis. TRIAL REGISTRATION ISRCTN: com ID: ISRCTN87606522.

The use of advanced-platelet rich fibrin (A-PRF) in the management of medication-related osteonecrosis of the jaw (MRONJ): A case report.

Medication-related osteonecrosis of the jaws (MRONJ) is a serious debilitating disease resulting from long-term treatment with Antiresorptive drugs such as Bisphosphonates or Denosumab, which significantly affects patients' quality of life. A 43-year-old female patient with stage 4 breast cancer and treated with Zoledronic Acid for bone metastases was referred to the Department of Oral Medicine at the Faculty of Dentistry, Damascus University. The main complaint was pain in the right maxilla. Intraoral examination showed an exposure of necrotic bone in the right maxillary region with presence of purulent exudate. The treatment plan was discussed with the patient. Treatment included resection of all necrotic bone and application of Advanced platelet-rich fibrin (A-PRF) clots and membranes. Follow-up and outcome were conducted by clinical measures to assess healing and recurrence (6-month follow-up). Topical treatment with A-PRF demonstrated a reduction in pain and resulted in complete wound healing within 30 days. A-PRF stimulates the release of growth factors and chemotaxis involved in tissue repair mechanisms. This method seemed to be effective in the treatment of MRONJ.

Efficacy of Hyaluronic Acid in Relieving Post-implantation Pain: A Split-Mouth Randomized Controlled Trial.

Background Many patients suffer from some degree of pain following the surgical procedures of dental implantation. The fear of pain may be one reason for postponing such prosthodontic treatments. Many procedures have been suggested to control post-implantation pain. This trial evaluated the effectiveness of using hyaluronic acid (HA) during dental implantation on patients' perceived pain during the postsurgical soft-tissue healing period. Methodology A split-mouth randomized controlled trial (RCT) was conducted. The trial sample consisted of 22 dental implants in 11 patients (five males and six females). Patients were selected from those attending the Department of Oral Medicine at the Faculty of Dentistry, University of Damascus between February 2021 and May 2022. The implants were performed in similar bone quality and density for each patient as the implants were inserted in the same jaw on both sides to ensure the same physiological conditions. The study sample was divided into two groups. The first group (the experimental group) consisted of 11 implants in which the implant site was drilled, following which HA was placed inside the implant site and on the surrounding bone before the flap was returned and sutured. The second group (the control group) comprised 11 implants following the conventional procedure without applying any material to the implant socket. The main outcome measure was pain perception which was assessed using the visual analog scale (VAS). Patients were asked to record their perceived pain on the first, third, and tenth days. Two-sample t-tests were used to detect significant differences. Results There were statistically significant differences in the mean pain intensity between the experimental and control groups on the first, third, and tenth days (p < 0.05). The mean values of perceived pain in the control group were 5.68, 1.72, and 0.56 on the first, third, and tenth days, respectively. In comparison, the mean values of perceived pain in the experimental group were 4.52, 1.14, and 0.18 on the first, third, and tenth days, respectively. The maximum perceived pain in the control group was 7.5 on the first day following implantation, whereas the maximum value recorded in the experimental group was 6.5. At the third assessment time (i.e., 10 days following the surgical intervention), the mean values were in the very mild category of pain intensity. Conclusions This study showed that applying HA in the implant cavity and on the surrounding bone effectively reduced pain after dental implant surgery in comparison with the control group. Patients had lower mean pain scores at one, three, and ten days following surgery compared to the conventional method. HA is suggested to be an adjunctive method to control postsurgical pain after dental implantation.

Assessment of the Effectiveness of Aloe vera Versus Amlexanox in the Treatment of Recurrent Aphthous Ulcers: A Three-Arm Placebo-Controlled Randomized Clinical Trial.

Background Recurrent aphthous ulcers are one of the most common lesions of the oral mucosa. Most currently available treatment methods aim to relieve symptoms, speed up healing and prevent ulcer recurrence. The current study aimed to compare the effectiveness of Aloe vera gel with that of amlexanox 5% oral paste in the treatment of recurrent small-type aphthous ulcers. Materials and Methods The study was conducted on 60 patients (27 males and 33 females) attending the Department of Oral Medicine at the Faculty of Dentistry at Damascus University. The sample age ranged between 15 to 25 years, with an average age of 20.3 ± 2.4 years. Patients were diagnosed with recurrent aphthous ulcers of the small type. The sample was divided into three groups with equal numbers of patients (n=20 for each group) according to the provided drug: Aloe vera, amlexanox, and the placebo groups. Patients' ulcer size was measured on day 0 of treatment, and the ulcer size reduction was assessed on day 3 and day 5. The pain was also recorded at the first visit, and then pain reduction was assessed during follow-up visits. Results The mean ulcer size on the fifth day of treatment was 1.85 mm2, 4.05 mm2, and 6.20 mm2 in the Aloe vera, the amlexanox, and the placebo groups, respectively. The differences between groups were significant (p=0.003). The mean pain on the fifth day was 0.80 cm, 1.60 cm, and 3.20 cm in the Aloe vera, the amlexanox, and the placebo groups, respectively. The differences between groups were significant (p=0.026). Conclusions Within the limits of the current trial, both treatment groups proved effective in accelerating ulcer healing with the superiority of Aloe vera compared to amlexanox, as it achieved a greater reduction in ulcer size and pain when assessed on the fifth day of treatment.
