Incidence of temporomandibular joint symptoms following whiplash injury.

Recently there has been considerable litigation involving the development of temporomandibular joint (TMJ) pain and dysfunction following cervical musculoskeletal injury (whiplash). The purpose of this investigation was to interview, examine, and follow up patients with a diagnosis of whiplash injury to determine the incidence of associated temporomandibular disorders. Patients were divided into two categories: those with and those without radiologic evidence of cervical skeletal injury. In the 63 patients with radiographic evidence of cervical skeletal injury (group 1), none had clicking at the time of initial examination. In the 92 patients without positive radiographs (group 2), only one had clicking. At 1 month follow-up by telephone, 2 of 51 available patients in group 1 had developed clicking, but no new TMJ symptoms were reported by the 78 patients in group 2 contacted by phone. Seventy percent of the initial follow-up group (44 patients) with radiographic evidence of injury were contacted by telephone at 1 year and none reported new symptoms of TMJ pain or clicking. Sixty-five percent of the initial follow-up group without radiographic evidence of injury (60 patients) were interviewed and also reported no new TMJ symptoms. These data indicate that the incidence of TMJ pain and clicking following whiplash injury is extremely low, and that patients who do not have clicking on resolution of their initial pain/dysfunction subsequently do not develop this problem.

Training of the oral and maxillofacial surgeon in implantology.

This article reports the results of a survey of oral and maxillofacial surgery residency programs regarding the teaching of implantology. The findings show that although oral and maxillofacial surgery residents receive as much or more didactic training than most trainees in other dental specialties, and much more extensive surgical experience, the teaching is not uniform and there is still need for improvement in some areas.

Bone formation over partially exposed implants using guided tissue generation.

This pilot study tested whether a semipermeable expanded polytetrafluoroethylene (e-PTFE) membrane could be used to induce new bone to cover the partially exposed surface of titanium and hydroxylapatite (HA)-coated endosseous implants. Twenty threaded titanium and 10 HA-coated implants were placed in the tibia of five mongrel dogs. The implants were placed in a manner that left the cervical 2 to 3 mm exposed. Fifteen implants were used as controls and the rest were covered with an e-PTFE membrane. Animals were killed at 6, 8, and 12 weeks. Those implants covered by the membrane showed a progressive formation of bone on the exposed portion. The threaded titanium control implants showed reactive periosteal bone formation in the adjacent area, but no new bone formation on the exposed threads. The HA-coated controls, however, showed progressive bone formation on the exposed portion. Membrane position appeared to have an effect on the quantity of bone that formed, as those test sites in which there was a collapse of the membrane against the implant showed less new bone than those in which a protected space was created. This study showed that guided tissue generation may be used to induce new bone to form over the exposed portion of an implant, that the amount of new bone is influenced by the width of the space between membrane and implant, and that new bone forms on an exposed HA-coated implant even in the absence of a guiding membrane.
