“…Studies showed no significant difference in terms of thermal sensitivity test after LLLT in treatment group/side compared to placebo even over 2 months after surgery (P > 0.05) [19,32,33]. Also, studies demonstrated that LLLT can reduce pain at 1 month after surgery based on the VAS test (P < 0.05) [19,34]. LLLT was significantly effective in augmenting directional discrimination (a test in which patients should detect the path of a nylon filament) at 1 month after LLLT (P < 0.05) [33,34].…”

“…Titles and abstracts screened based on inclusion and exclusion criteria and 14 studies were retrieved and assessed for full-text evaluation based on the pre-determined inclusion and exclusion criteria and the assumed research question. Hence, five studies were excluded, and finally, eight studies were assessed for qualitative synthesis and five for metaanalysis [13,[17][18][19][31][32][33][34] (Fig. 1).…”

“…Six studies were double-blind, one was single-blind and one was tripleblind randomized controlled trials. Also, four studies had the split-mouth design in which one side of the lower jaw was radiated by laser and the other side subjected to LLLT without radiation as placebo [13,18,31,34] and four had two separate treatment (test) and control (non-treated) groups [17,19,32,33]. The latest study was conducted in 2020.…”

“…Four studies have evaluated the effectiveness of LLLT in a short period of time (immediately after to 48 h after surgery) using the 2-point discrimination neurosensory test [13,18,33,34]. In this test, a patient perceives the distance between the two touch stimuli with a relatively sharp tip on the skin surface.…”

“…Four studies have examined the effectiveness of LLLT on recovery from neurosensory disturbance using general sensitivity tests dominantly via the visual analog scale (VAS) [17,18,33,34]. Based on the result of the analysis, it can be observed that the LLLT is not effective in a short period (0 to 48 h) after surgery (WMD 0.11, 95% CI: −0.19~0.41, I 2 = 0%, no heterogeneity).…”

Background Orthognathic surgery such as bilateral sagittal split ramus osteotomy (BSSRO) for the treatment of mandibular deformities is one of the most common procedures in maxillofacial operations that may lead to neurosensory disturbance. In this study, we aimed to evaluate the effectiveness of low-level laser therapy (LLLT) on augmenting recovery of neurosensory disturbance of inferior alveolar nerve (IAN) in patients who underwent BSSRO surgery. Methods A comprehensive literature search was conducted by two independent authors in PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Embase, and Google Scholar electronic databases. Besides, a manual search of all textbooks and relevant articles were conducted. Searches took place in August 2020 and were limited to published and peer-reviewed articles from 2000 to 2020. All analysis was performed using the comprehensive meta-analysis (CMA) and the STATA MP (version:16) software. The weighted mean difference (WMD) using the inverse variance method and the standard mean difference (SMD) was considered for continuous variables. Results Seventy-four papers were retrieved after removing duplicate studies and finally, eight studies were assessed for qualitative synthesis and five for meta-analysis. Totally, 94 patients were included in the meta-analysis. Based on the meta-analysis, it was shown that LLLT was not effective in a short interval (0 to 48 h) after surgery, but in a period of more than 1 month after surgery, the positive results of treatment can be observed strikingly. Also, LLLT side/group showed no significant difference in some aspects of neurosensory recovery such as thermal sensation compared to the placebo side/group. Conclusions The meta-analysis of randomized controlled trials revealed that LLLT generally improves IAN sensory disturbance caused by BSSRO. Further high-quality clinical trials with longer follow-up periods and larger sample sizes are recommended.

The use of photobiomodulation therapy (PBMT) may be used for treating trauma to the maxillofacial region. The effects of PBMT on maxillofacial injuries were discussed in this review article. The electronic databases Pubmed, Scopus, and Web of Science were thoroughly searched. This review included in vitro, in vivo, and clinical studies describing how PBMT can be used in maxillofacial tissue engineering and regenerative medicine. Some studies suggest that PBMT may offer a promising therapy for traumatic maxillofacial injuries because it can stimulate the differentiation and proliferation of various cells, including dental pulp cells and mesenchymal stem cells, enhancing bone regeneration and osseointegration. PBMT reduces pain and swelling after oral surgery and tooth extraction in human and animal models of maxillofacial injuries. Patients with temporomandibular disorders also benefit from PBMT in terms of reduced inflammation and symptoms. PBMT still has some limitations, such as the need for standardizing parameters. PBMT must also be evaluated further in randomized controlled trials in various maxillofacial injuries. As a result, PBMT offers a safe and noninvasive treatment option for patients suffering from traumatic maxillofacial injuries. PBMT still requires further research to establish its efficacy in clinical practice and determine the optimal parameters.

This study aimed to evaluate the effectiveness of photobiomodulation (PBM) therapy using 940‐nm laser in patients undergoing orthognathic surgery. Twenty individuals were randomly distributed into laser (n = 10) and control (n = 10) groups. The PBM was conducted immediately after surgery, after 24 h, 48 h, and weekly for up to 4 weeks. All participants were evaluated for pain, edema, trismus and paresthesia. Data were compared by Fisher's and Mann–Whitney or chi‐square tests (5%). The pain decreased from 24 h to 4 weeks, with the laser group reaching any pain after 3 weeks (p < 0.001). A significant difference was noticed for trismus on days 14 and 30 (p = 0.002; p = 0.019), without difference in paresthesia (p = 0.198). Edema was lower on the laser group compared to control, without a significant difference for most measurements. Data indicate that 940‐nm PBM therapy decreased the occurrence of postoperative pain and significantly improved trismus.
