Reduction of dental fear: psychophysiological correlates

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.     

Body mass index and adult female urinary incontinence

Summary The aim of the present investigation was to study the possible role of obesity in the etiology of adult female urinary incontinence (UI). A random population sample of 3,114 women aged 30–59 years were mailed a questionnaire concerning UI and, among other things, body weight and height. The overall rate of response was 85%, and the present analysis comprises 2,589 women who supplied information about their body weight and height. The period prevalence of all UI, stress UI, urge UI, and mixed stress and urge UI was 17%, 15%, 9%, and 7%, respectively. The mean body mass index (BMI) was 22.7 kg/m². Irrespective of other risk indicators, BMI was positively associated with UI prevalence (OR, 1.07/BMI unit; P<0.0001). BMI interacted with childbirth in predicting stress UI prevalence, with cystitis in predicting urge UI, and with both in predicting mixed UI. Stress UI proved to be the UI type most closely associated with BMI.     

Rapid orthodontic extrusion of crown root and cervical root fractured teeth

Abstract This study concerns the relapse tendency and extent of root resorption in 33 extruded non-vital crown root fractured or cervical root fractured teeth in 32 patients 10–20 years old. They constitute all orthodontically extruded teeth at the Orthodontic or Pedodontic Departments, Eastman Institutet, Stockholm (1982–1987). A simple extrusion mechanism exerted a force of 60–70 p along the root axis of the tooth. An extrusion of 2–3 mm was obtained in most patients; the most extreme effect was 6 mm. In 16 patients the extrusion was achieved within 3 weeks, in 12 it lasted for 4–6 weeks and in 5, 7–9 weeks. The treatment was more complicated in the lower jaw. After the extrusion, a fibrotomy was done and in most patients also a gingival recon–touring to create an optimal relation between the gingiva and the margin of the restoration. Periodically identical radiographs were taken immediately before and after the extrusion, after 3 months and after 1 year. A minor relapse, about 0.5 mm, was observed in 3 patients. Limited root resorption was found in 6 teeth and severe in only 1. The resorptions did not progress in the following 2 years of observation.
