“…The anaesthesia induced by low-power infrared Nd:YAG laser generates high peak power pulses with deep tissue penetration and minimal heat generation 12) and the consistency of such laser-induced anaesthesia reported by our clinical trial and the studies [7][8][9][10][11] above has led to considerable interest in the use of such laser pulpal anaesthesia during restorative dental procedures 13, 14) -a procedure which does not induce injection-related anxiety, numbness or unpleasant tastes. The strong evidence of its effectiveness shown in our clinical trial and from animal studies is consistent with a neural basis resulting in conduction block, the mechanism by which laser-induced photo-bio-inhibition achieves dental anaesthesia.…”

“…In Half of the patients, PBM was applied before starting work and the other half was not irradiated and finally it was observed that children had less pain in Laser 95% CI the laser group. 11 It has been reported in some studies that PBM can be effective in anesthesia and pain, the addition of gallium-aluminum-arsenide laser irradiation to intravenous regional anesthesia is safe, and reduces pain during and after the operation. 4 The results of these 2 studies was in line with our study.…”

IntroductionAchieving appropriate anesthesia in mandibular molar teeth with irreversible pulpitis is one of the most challenging aspects of root canal treatment.1 It is more complicated in teeth with symptomatic irreversible pulpitis.2 Inferior alveolar nerve block is not profoundly successful in mandibular teeth with symptomatic irreversible pulpitis and sometimes supplemental techniques are necessary. 3Nowadays photobiomodulation (PBM) is considered as an adjunct in anesthesia, the addition of galliumaluminum-arsenide laser irradiation to intravenous regional anesthesia is safe, and reduces pain during and after the operation. The most local anesthetics in dentistry block sodium channels. Tetrodotoxin resistance sodium channels are resistant to local anesthetics and sensitized by prostaglandins. 5PBM has been used in dentistry for its anti-inflammatory, 6 regeneration 7 and analgesic 4 properties. It can prevent nerve impulse conduction. Studies have shown that laser irradiation prevents axonal transmission of signals in nerve fibers A-delta and C, since nociceptive signals are transmitted by the fibers of to the spinal cord, it is likely that laser radiation reduces the transmission and subsequently reduces the feeling of pain.8 PBM effectiveness was shown in reducing pain after root canal therapy, 9 but it hasn't been used as an adjunct in anesthesia in dentistry. Some PBM applications in dentistry include the following: To control pain, swelling and inflammation after surgery thus reducing the need for medication. 10To reduce pain after tooth fillings or dentin cutting with an inhibitory effect on the pulp nervous system. 11The anti-inflammatory mechanism of PBM and its Abstract Introduction: Achieving appropriate anesthesia in patients with symptomatic irreversible pulpitis in mandibular molars during endodontic treatment is always one of the most challenging aspects. Photobiomodulation (PBM) has been used in dentistry due to its anti-inflammatory properties and regenerative effects. This study evaluates the effects of PBM in the depth of anesthesia in inferior alveolar nerve block. Methods:In this randomized clinical trial, 44 patients requiring endodontic treatment in lower molar, left or right were selected, half of them were randomly treated with PBM therapy. Laser irradiation by 980 nm diode laser with a single dose (15 J/cm 2 , for 20 seconds) before anesthesia was performed at the buccal aspect. Inferior alveolar nerve block was performed once. Success was defined as no or mild pain (no need for any supplemental injection), based on the visual analogue scale during access cavity preparation. Results were evaluated using SPSS software. Results:The results of this study showed that the necessity for supplemental injection was lower in the group receiving laser than in the group without laser (P = 0.033). The mean pain intensity during dentin cutting was lower in the group receiving laser than in the group without laser (P = 0.031). Also, the mean pain intensity during pulp dropping was lower in the gr...

“…As the tip is not in contact with the tooth surface, this method of cavity preparation is much more agreeable to the patient [6][7][8]. In addition, many other studies have reported that lasers produce a mild local anesthetic effect, which allows for shallow cavity preparations to be completed without local analgesia [9,29]. Pain perception, however, during different types of laser cavity preparations remains unpredictable and is a puzzlement to many dental practitioners.…”

“…Lasers have been shown to produce 400 times less vibration, than does a burr preparation [6], and achieve an improved patient experience, as evidenced by a number of pediatric studies. These findings were based upon a change to a more pleasant sound, less vibration, and to a certain degree, low-level laser therapy effect [7][8][9], which acts to provide a form of analgesia. Furthermore, a simple signaling system, such as a Braised hand^to indicate discomfort and request stop of the procedure, gives control to the patient and is particularly useful in decreasing anxiety in both children and adults [10].…”

Aim The study recorded 400 responses from 301 patients, aged 6-93, who all had carious lesions prepared with the erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) 2780-nm laser system. Different parameters, including gender, delivery method, power settings, tooth position, class type of cavity preparation, and patients' age, were compared and analyzed for possible predictive values in anticipating the patients' pain experience. Methods Class 1-5 cavity preparations were made using the Er,Cr:YSGG laser. All carious lesions fit ICDAS code 4-5 classifications. Power setting of 3.75 W was used for posterior teeth class 1-4 preparations and 2.5 W for all primary teeth, permanent anterior teeth, and all class 5 preparations. Nonanxious patients, who agreed to start cavity preparation without a local anesthetic, were instructed to stop the procedure and ask for an anesthetic injection, should they perceive a level of pain greater than their tolerance level. Anxious patients were not included in this study. Pain perception using the visual analog scale (VAS) along with the percentage of patients who needed a local anesthesia injection were recorded. The data was then analyzed using one-way ANOVA test, at significance level of α = 0.05, and Tukey pair-wise comparison, at 95% confidence interval. Results Eighty-five percent of cavity preparations were pain free; 15% of the preparations were found to have a degree of pain associated with them. However, only 6% requested a local anesthetic injection. There was no significant difference found between the two methods of delivery: gold handpiece (HP) vs. turbo HP. No significant differences were observed between males and females, regarding pain perception (13% vs. 18%, respectively). Posterior teeth were significantly more sensitive to laser cavity preparation, compared to anterior teeth, as indicated by the VAS pain scores (P value = 0.0001). Regarding anterior teeth, class 5 was significantly more sensitive to laser cavity preparations, when compared to class 1. In posterior teeth, there were no statistically significant differences between class 1 and 5, although pain perception was the most prevalent in class 2 preparations. Using higher-power settings (3.75 W vs. 2.5 W) for cavity preparation, the resulting pain response was significantly higher, as indicated by the VAS pain scores (P value = 0.0001). As the patients' age increases, the frequency of those experiencing pain decreases, with the exception of a sudden spike for the cohort aged 26-35, who proved to be the most sensitive to laser cavity preparation; this group was significantly different from all other age groups (P value = 0.0001). Conclusions The Er,Cr:YSGG laser system is an effective method for pain-free cavity preparations for 85% of the general patient population, who do not suffer from dental anxiety. Certain patient selection criteria, including age, power settings, and class type of cavity preparation, are important in achieving an overall positive and pain-free expedience.
