There are no significant differences in perception of pain produced by penetrations of 25-, 27-, and 30-gauge needles in the retromolar fossa. Six dentists received three series of six needle penetrations, three in each retromolar fossa, at one-week intervals. The penetrations were made to a depth of 2 to 3 mm with use of a rapid in-and-out motion by 25-, 27-, and 30-gauge needles in an alternating sequence. The perception of pain for each penetration was recorded, tabulated, and statistically analyzed. There were no significant differences in the perception of pain elicited from the use of the three needles.
在磨牙后窝，25号、27号和30号针头穿刺产生的疼痛感知没有显著差异。六名牙医每隔一周接受三组，每组六次针头穿刺，每次在每个磨牙后窝穿刺三次。使用25号、27号和30号针头以快速进出动作交替进行穿刺，深度为2至3毫米。记录每次穿刺的疼痛感知，制成表格并进行统计分析。使用这三种针头引起的疼痛感知没有显著差异。
