This survey investigated the availability of nerve block using mepivacaine hydrochloride solution for dental treatment. One hundred and eight consenting patients aged between 16 and 80 years who required a nerve block for dental treatment participated in this survey at one of five hospitals accredited by the Japanese Dental Society of Anesthesiology. The patients included 45 males and 63 females. Eighty-seven patients underwent tooth extraction. The nerve block included the inferior alveolar nerve block (n=106), the posterior superior alveolar nerve block (n=1), and the nasopalatine nerve block (n=1). For the inferior alveolar nerve block, 1.8 ml of mepivacaine hydrochloride solution was administered to 82 patients. The onset time was 4.5±2.0 min, and the duration was 166.3±75.4 min. Sixty-eight patients felt no pain, and 23 patients felt negligible pain. A nerve block using mepivacaine hydrochloride solution was evaluated as being effective in 100 patients and somewhat effective in 5 patients. No adverse events, including hemorrhage, were reported. Nerve block using mepivacaine hydrochloride solution was evaluated as being available for 105 patients. As a result, nerve block using mepivacaine hydrochloride solution was evaluated as being both effective and available in 100 patients. Nerve block using mepivacaine hydrochloride solution for dental treatment should be considered, since many dental patients have cardiovascular comorbidities in Japan's superaged society and this trend is likely to continue.
