The aim of the study was to demonstrate if 2% lidocaine hydrochloride with 1:200,000 epinephrine could provide palatal anesthesia in maxillary tooth removal with a single buccal injection. The subjects included in the clinical study were those requiring extraction of the maxillary third molar of either side. For the purpose of comparison, the sample was randomly divided into 2 main groups: group 1 (study group) included 100 subjects who were to receive a single injection before extraction, and group 2 (control group) included 100 subjects who were to receive a single buccal injection and a single palatal injection before extraction. After 5 minutes the extraction was performed. All patients were observed for Faces Pain Scale during extraction and asked for the same on a 100-mm visual analog scale after extraction. According to visual analog scale and Faces Pain Scale scores, when maxillary third molar removal without palatal injection (study group) and with palatal injection (control group) were compared the difference was not statistically significant (P > .05). Removal of maxillary third molars without palatal injection is possible by depositing 2 mL of 2% lidocaine hydrochloride with 1:200,000 epinephrine to the buccal vestibule of the tooth.
本研究的目的是证明含1:200,000肾上腺素的2%盐酸利多卡因通过单次颊侧注射能否在上颌牙拔除术中提供腭部麻醉。纳入临床研究的受试者为需要拔除双侧上颌第三磨牙的患者。为了进行比较，样本被随机分为2个主要组：第1组（研究组）包括100名在拔牙前接受单次注射的受试者，第2组（对照组）包括100名在拔牙前接受单次颊侧注射和单次腭侧注射的受试者。5分钟后进行拔牙。在拔牙过程中观察所有患者的面部疼痛量表评分，并在拔牙后要求他们在100毫米视觉模拟量表上进行评分。根据视觉模拟量表和面部疼痛量表评分，比较上颌第三磨牙拔除术在不进行腭侧注射（研究组）和进行腭侧注射（对照组）时的差异，差异无统计学意义（P>.05）。通过将2毫升含1:200,000肾上腺素的2%盐酸利多卡因注入牙齿的颊侧前庭，不进行腭侧注射拔除上颌第三磨牙是可行的。
