- EMG, HR and SCR were continuously recorded during two Standardized Dental Examinations (SDE) of 15 dental phobics. Following the first SDE, the patients were assigned to two treatment groups, one receiving systematic desensitization followed by two separate amalgam restorations and one premedicated with Valium for the two restorations. The dentist rated the patients' behavior on a 5-point scale. Corah's Dental Anxiety Scale (DAS) was used prior to the first SDE and following the second SDE. The second SDE was conducted on a separate occasion following the second restoration. No significant correlations were found between any of the physiological measures and either the dentist's ratings or the second DAS or DAS change scores. Significant differences found between the two treatment groups on the dentist's ratings, second DAS, and change scores were not reflected by the physiological measures.

- Insufficient bone volume may be a significant problem in connection with dental implants. In this study, a technique based on the principle of guided tissue regeneration was tested for its ability to generate bone tissue around titanium implants. Implants were inserted in tibiae of rabbits. To create a secluded space for osteogenesis and to prevent soft-tissue ingrowth, a porous Teflon membrane was placed around exposed parts of the implant. Where a membrane had been used, the threads of the implant were completely covered with significant amounts of new bone. This study indicates that the membrane technique is a reconstructive surgical method that may be applicable to create new bone around exposed parts of titanium implants in a clinical setting.
