Condylar resorption after bicortical screw fixation of mandibular advancement.

Purpose: This study evaluated long-term condylar resorption after mandibular advancements stabilized with bicortical screws.

Patients And Methods: One hundred mandibular deficiency patients who underwent bilateral sagittal split osteotomies (BSSO) fixed with three bicortical screws per side, and who were followed for a minimum of 1 year with complete radiographic records, were evaluated. Preoperative panoramic radiographs were traced and superimposed as a best fit over long-term panoramic radiographs.

The effect of stannous fluoride on dentinal hypersensitivity.

Many agents have shown varying degrees of effectiveness on pain resulting from exposed dentine. One which has shown some promising results is stannous fluoride (SnF2). The purpose of the following paper is twofold: to review and summarise the clinical literature pertaining to the relative effectiveness of solutions or gels containing SnF2 in controlling pain associated with dentinal hypersensitivity; and to statistically re-evaluate these studies in combination, in order to develop recommendations for the optimal use of SnF2 for hypersensitivity.

Effect of a fluoride solution on dentinal hypersensitivity.

This two-phase experiment assessed the effects over time of a solution containing 1.09% sodium fluoride, .40% stannous fluoride, and .

Electrophysiological assessment of human inferior alveolar nerve function.

This study describes a technique for making electrophysiological recordings from the inferior alveolar nerve of conscious human subjects. Recordings were obtained from 6 of 10 subjects, with consistent waveform latencies and amplitudes across subjects. The neurogenic origin of the responses was verified by blocking the nerve with 2% xylocaine, resulting in a loss of the waveform.
