Abstract: The present invention relates to a novel applicator for topical anesthetics and a method using said novel applicator which provides for pain-free injections in mucosa by the application of a topical anesthetic followed by an injection limited to penetrate the mucosa only to the extent of penetration of the topical anesthetic. The method is accomplished by applying a topical anesthetic to the desired mucosal area by means of a novel applicator swab, comprising a handle on which is attached an absorbent material and an abrasive portion. The swab is dipped in topical anesthetic and placed at the desired oral location, where the abrasive portion is used to mildly abrade the oral mucosa. The application of the topical is then followed with an injection which penetrates the tissues only to the extent of penetration of the topical anesthetic.

Abstract: The present invention relates to a dental method and means to allow pain-free injections in mucosa by the application of a topical anesthetic followed by an injection limited to penetrate the mucosa only to the extent of penetration of the topical anesthetic. The method is accomplished by applying a topical anesthetic to the desired mucosal area, and following the topical application with an injection, which penetrates the tissues only to the extent of penetration of the topical anesthetic. Various devices of fixed length are described which limit the penetration of the injection such as a drastically truncated syringe needle, a sheath fitted to and covering the needle, a needle shield, and a speculum.
