“…Many mechanisms for local anaesthetic failure have been discussed elsewhere; [52][53][54][55] it is believed that articaine may provide anaesthetic success when other LAs are unable to provide profound anaesthesia. 2 Teeth with irreversible pulpitis (IP) are perceived to be more difficult to anaesthetise than those with normal pulps because nerves arising from inflamed tissue have altered resting potentials and decreased excitability thresholds.…”

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...

“…Many techniques have been advocated for the inferior alveolar nerve block; however the Fischer's technique seems to be the one which is most widely practiced. Unfortunately this technique is marred with a failure rate of approximately forty-five percent [3]. This may be due to the fact that the needle on insertion in the tissue approaches the medial surface of the ramus at an acute angle.…”

“…However, the conventional technique is reported to have been associated with risks and complications such as neural or vascular injury, intravascular injection and failure to achieve adequate anesthesia. Improper technique was deemed to be one of the major factors contributing to the failure of a desired result which has been reported as high as thirty-five to forty-five percent [2][3][4] In our study, we altered the insertion angle of the needle by arching it to achieve a near perpendicular angle with the ramus, resulting in a more accurate deposition of the anesthetic solution thus lowering the incidence of failure to achieve desired anesthesia.…”

One of the most commonly used local anesthetic techniques in dentistry is the Fischer's technique for the inferior alveolar nerve block. Incidentally this technique also suffers the maximum failure rate of approximately 35-45%. We studied a method of inferior alveolar nerve block by injecting a local anesthetic solution into the pterygomandibular space by arching and changing the approach angle of the conventional technique and estimated its efficacy. The needle after the initial insertion is arched and inserted in a manner that it approaches the medial surface of the ramus at an angle almost perpendicular to it. The technique was applied to 100 patients for mandibular molar extraction and the anesthetic effects were assessed. A success rate of 98% was obtained.
