OBJECTIVE The purpose of this prospective randomized study was to measure the degree of anesthesia obtained with unilateral and bilateral inferior alveolar nerve blocks to determine whether cross innervation occurs in anterior teeth. STUDY DESIGN Through use of a repeated-measures design, 38 subjects randomly received unilateral or bilateral inferior(More)
To determine whether a repeated intraosseous (IO) injection would increase or prolong pulpal anesthesia, we measured the degree of anesthesia obtained by a repeated IO injection given 30 min following a combination inferior alveolar nerve block/intraosseous injection (IAN/IO) in mandibular second premolars and in first and second molars. Using a(More)
The purpose of this study was to measure the degree of anesthesia obtained with the incisive nerve block, the inferior alveolar nerve block and a combination of both injections in mandibular teeth. Using a repeated measures design, 40 subjects randomly received an incisive nerve block, a conventional inferior alveolar nerve block, or a combination inferior(More)
The purpose of this study was to determine the contribution of the intraosseous (IO) injection to the inferior alveolar nerve (IAN) block in human first molars. Using a repeated-measures design, 40 subjects randomly received either a combination IAN block + IO injection (on the distal of the first molar) using 2% lidocaine with 1:100,000 epinephrine or an(More)
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-,(More)

An evaluation of volumes and concentrations of lidocaine in human inferior alveolar nerve block. An evaluation of 4% prilocaine and 3% mepivacaine compared with 2% lidocaine (1:100,000 epinephrine) for inferior alveolar nerve block. An evaluation of lidocaine hydrocarbonate compared with lidocaine hydrochloride for inferior alveolar nerve block. An(More)
