Abstract Objectives The present systematic review aimed to evaluate whether the IANB (conventional inferior alveolar nerve block) technique is superior to the VA (Vazirani-Akinosi) or GG (Gow-Gates) techniques for anesthesia in the removal of posterior mandibular teeth. Materials and methods This systematic review was structured according to the PICO strategy, adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist, and was recorded on the international prospective register of systematic reviews (PROSPERO—CRD42020153130). Studies were included based on the eligibility criteria and data from the included studies were collected by one author, while another reviewed the compilation. Results Eight studies were included, all of which were randomized controlled trials. Three studies tested the techniques by exclusively performing lower third molar removal; the others covered other posterior lower teeth. All studies used the same local anesthetic and the same vasoconstrictor: lidocaine 2% with epinephrine/adrenaline. A total of 1056 patients were evaluated. Conclusions Some differences were observed between the techniques. Because of the heterogeneity between studies, clinical trials with more specific methodologies, such as comparisons of GG and VA with IANB for mandibular tooth removal, and the same clinical homogeneity will be worthwhile. Clinical relevance A systematic review of which anesthetic technique is most effective for mandibular teeth removal may positively impact the population’s life. There are no systematic reviews which approach this theme in a well-structured perspective. Keywords Anesthetics . Oral surgery . IANB . Vazirani-Akinosi . Gow-Gates . Systematic review
Introduction Local anesthetic solutions are routinely used in dental procedures to reduce pain through reversible nerve block [1, 2]. Mandibular anesthesia can be performed in many ways, including the conventional inferior alveolar nerve block (IANB) * Belmiro Cavalcanti do Egito Vasconcelos [email protected] 1
