In dental clinic, dentists usually use the needles of 27G (diameter : 0.41 mm) for regional anesthesia and 30G (diameter : 0.32 mm) for infiltration anesthesia. The new needle made for infiltration is 31G (diameter : 0.28 mm) to alleviate needle penetration pain. The effects of needle diameter on penetration pain was assessed at the canine or first molar mucobuccal region by using visual analog scale (VAS). There were significant differences between the group given topical anesthesia and the groups not given in 27G and 30G needle diameters at the cainine region. Topical anesthesia is effective for the needle diameter of 30G and larger. For 31G, however, topical anesthesia is not involved in penetration pain at the canine region or at the molar region.
