“…The distance between the target tissue and the laser probe was constant due to the silicon piece (hollow in the middle) prepared for the laser probe. The application of the laser energy was at a power of 300 mW (0.3 W) for a duration of 20 s, similar to a previous study 15 (Figure 1B). The energy density was calculated as 69 J/cm 2 .…”

“…There was no correlation between age and the patient preference, as reported by Seraj et al 11 and Ghabraei et al 15 It is generally observed that children who experience pain during their dentist visit are less likely to cooperate in future visits and dental treatments, and less likely to go to future dental visits as compared to adult patients. Due to this, the current study focused on children who are aged 6 and over, considering that young children may not tolerate pulpotomy treatment in the first sessions of dental visit, which can be identified as a limitation of this study.…”

“…Similarly, Tuk et al 13 evaluated pre-injection analgesic effects of LLLT (wavelength-810 nm; continuous mode, output power-198 mW; energy-5.94 J) in patients undergoing third molar removal and reported that LLLT was not effective in decreasing the pain felt during the administration of the local anesthetic injections. On the contrary, Jagtap et al 14 (wavelength-660nm; output power-0.6 W; 3 min) and Ghabraei et al 15 (wavelength-980nm; contact mode, output power-0.3 W; 20 s; 15.62 J/ cm 2 ; 0.384 cm 2 focal spot area; energy-6 J) concluded that LLLT before the injection of local anesthesia reduced injection pain in adults. There are many parameters that determine the effect of LLLT, and thus, the differences in these parameters make it challenging to compare across studies.…”

“…4,6 Considering the effects of LLLT on microcirculation reported by various researchers in the literature, [8][9][10] it is thought that improvements in local circulation and increased vasodilation may increase the absorption of the local anesthetic agent. 6,11 The use of LLLT to reduce injection-related pain is reported in a limited number of studies in adult patients, 7,[12][13][14][15] but consistent results have not been obtained with these studies due to different clinical effects of changing laser parameters. In other words, there is no consensus on ideal laser parameters.…”

Background The use of low level laser therapy (LLLT) to reduce injection pain associated with dental local anesthesia is reported in a limited number of studies in adults, but research on the effects of LLLT in children is needed. Aim This study aimed to evaluate the effects of topical anesthesia + LLLT on injection pain, anesthesia efficacy, and duration in local anesthesia of children who are undergoing pulpotomy treatment. Design The study was conducted as a randomized, controlled‐crossover, double‐blind clinical trial with 60 children aged 6–9 years. Before local infiltration anesthesia was administered, only topical anesthesia was applied in one side (control group/CG), and topical anesthesia plus LLLT (a diode laser: 810 nm; continuous mode; 0.3W; 20 s; 69 J/cm2) was applied in the contralateral side (LG) as pre‐anesthesia. The injection pain and anesthesia efficacy were evaluated subjectively and objectively using the Wong‐Baker Faces Pain Rating Scale (PRS) and the Face, Legs, Activity, Cry, Consolability (FLACC) scale respectively. Data were analyzed for statistical significance (p < .05). Results The “no pain” and “severe pain” rates in the PRS were 41.7% and 3.3% for the LG and 21.7% and 11.7% for the CG, respectively, during injection. Similarly, in the FLACC data, the number of “no pain” responses was higher for the LG than the CG (40%, 33.3%) and no “severe pain” rate was observed in both groups. The only statistically significant difference found for the PRS was p < .05. The median pain score was “0” for the LG and the CG in the FLACC data for the evaluation of anesthesia efficacy, and there was no statistically significant difference between the groups in terms of pain and anesthesia duration (p > .05). Also, most of the children preferred injection with topical anesthesia + LLLT (66.7%). Conclusions It has been determined that the application of topical anesthesia + LLLT with an 810‐nm diode laser before local infiltration anesthesia reduced injection pain and did not have an effect on anesthesia efficacy and duration in children.

The objective of this split‐mouth case report is to evaluate the effect of photobiomodulation (PBM, 880 nm) on pain control during pterygomandibular puncture. A patient received anesthesia on both sides of the mouth in a randomized manner. On the right side, an 880‐nm infrared laser was applied immediately before local anesthesia. On the left side, a sham laser was applied using the same technique. There was a 50% reduction in pain levels on the PBM‐treated side compared to the PBM‐sham side, as measured by the visual analog scale. Sensitivity tests revealed that anesthesia was more effective on the PBM side. There was no difference in blood pressure. This case report suggests that PBM (880 nm) before anesthesia may alleviate puncture pain associated with pterygomandibular anesthesia. Although these findings are based on a single case report, they can serve as the initial stepping stone for further randomized clinical trials.
