Effect of Low Level Laser Therapy (LLLT) on muscle pain in temporomandibular disorders – an update of literature

Purpose This study aimed to compare and find out the best treatment method between Laser (635 ± 10 nm), (US) and a combination of (US/Laser 635 ± 10 nm) in treatment of Temporomandibular disorders (TMDs). Methods This prospective study was done at the Department of Oral and Maxillofacial Surgery, AL Imam Ali Hospital in Al-Sadr City, and the oral medicine clinic at specialized curve center in Baghdad from January to August 2024. The study was carried out on (75) TMD patients, (25) of them were treated with (Laser635 ± 10nm), (25) were treated with (US) and (25) were treated with a combination of (US/Laser 635 ± 10 nm) in four treatment sessions (two sessions every week). The average power in laser treatment was 0.3 Watts, irradiation time: 30 seconds on each tender point. The average power in US treatment was 0.5 Watts, and application time was 3 minutes. Numbers of tender points were measured by palpation, and mouth opening was measured by electronic digital caliper. Pain intensity was recorded on a scale from 1 to 10 using rating visual analog scale (VAS). Results The most common age group was (20–29) years among all age groups and the mean age was (28.7 ± 8.4) years, and female patients were highly dominated (85.3%) over males (14.7%). The (laser 635 ± 10 nm) group showed significantly lower pain intensity, larger mouth opening, when compared with US treated patients in all the 4 treatment sessions. As a comparison between groups at different time periods, before second session, laser (635 ± 10 nm) group had the lowest pain intensity (p = 0.000). Before third session, laser (635 ± 10 nm) group had the lowest pain intensity, followed by (US/laser635 ± 10 nm) group (p = 0.000). Mouth opening was significantly largest (P = 0.010) in laser (635 ± 10 nm) group, followed by (US/laser 635 ± 10 nm) group. Before fourth session, the same significant results regarding pain intensity and mouth opening were obtained (P = 0.000). One month later, the same previous significant results regarding pain intensity and mouth opening (P = 0.000) were achieved. Number of masseter tender points was significantly lower (P = 0.028) in (laser 635 ± 10 nm) group as compared with (US/Laser 635 ± 10 nm) group. Conclusions The treatment of TMD patients with (laser 635 ± 10 nm) was shown to be more effective than treatment with (US) and with a combination of (US/Laser635 ± 10 nm) in reducing pain intensity and mouth opening.

Aim To clinically compare treatment of TMDs using hard occlusal stent constructed by CAD/CAM technology, low-level laser therapy (LLLT) and a combination of hard occlusal stent and LLLT. Patients and methods Twenty-one adult patients have suffered from chronic myofascial pain for at least three months. The patients were randomly divided into three equal groups based on the kind of treatment. Group A: Patients have received hard occlusal stent constructed by CAD/CAM technology. Group B: Patients have received LLLT. Group C: Patients have received a combination of hard occlusal stents constructed by CAD/CAM technology and LLLT. Clinical evaluations were done using Visual Analogue Scale (VAS) evaluation before therapy, at the fifth week, the third and sixth months after the onset of the study period. Data at the end of the trial was gathered, tabulated and statistically analyzed. Results Clinical results revealed that all three groups showed a general improvement in TMDs symptoms throughout the study period. The improvement was significant in all the study group periods. There was no statistically significant difference between the groups. Conclusions It has been established that the CAD/CAM occlusal stent, LLLT, and combination of CAD/CAM occlusal stent and LLLT enhances patient satisfaction and pain alleviation in individuals with TMDs.
