Oral hygiene instruction using a self inspection plaque index.

The need for proper oral hygiene requires large amounts of time and manpower, and relapse is still common. This paper describes a self instructional manual and self inspection plaque index that was tested in a periodontal recall population. The program was tested on 18 periodontal recall patients over a period of 6 weeks. Questionnaires were completed at the start, at 2 weeks, and at the end of the experimental period to evaluate patient opinions. Presence of plaque near the gingival margin was recorded at the start, at 2 weeks, and at 6 weeks. Patients were provided with a self instructional manual which taught them to recognize plaque on six teeth. Also, they were given a lighted mouth mirror, a toothbrush, and disclosing wafers. Initial, before-brushing plaque scores of 47% decreased to 18% during the 6 weeks of the study. After-brushing plaque scores also were significantly improved during the study. Patients were able to perform the plaque index without guidance to a high level of agreement with a dental hygienist (r = 0.72). Furthermore, the program was well accepted by the patients according to their answers on the questionnaire.

Prenatal diagnosis of occipital encephalocele by ultrasound scanning.

Fetal visualization in utero can be routinely accomplished using noninvasive ultrasound techniques that do not administer ionizing radiation. Image resolution with real time sonography is sufficient to demonstrate details of possible congenital central nervous system malformations before delivery. The case reported illustrates the advantages of advance warning in an infant with occipital meningoencephalocele for determining prognosis, planning delivery by cesarean section, and preparing for immediate neurosurgical repair.

A study of treatment planning: periodontal services for the elderly.

A study was undertaken to explore how dentists use patient data to plan treatment. Three hundred forty-six general dentists used oral and general health findings to determine periodontal treatment for seven prototypic elderly patients. The results indicated that oral hygiene and major medications best discriminated between treatment plans. The number of periodontal services ordered was directly related to the number of restorative units and inversely related to the number of extractions and prosthetic devices. Differences between dentists were not accounted for by the training, experience, or attitudes of the dentists.

Determinants of the quality of restorative dental care.

This article reports the results of an analysis to determine the relationships between the quality of restorative dental care for 1,466 patients and 9 categories of dentist characteristics for 102 volunteer Washington practitioners. In this study, patients were recalled and restorations were examined clinically. Questionnaires were administered to patients and dentists. The dependent measure is a weighted average of scores for operative dentistry and crown and bridge. Stagewise regression was used to adjust for differences in patient oral health and assessor bias. Models were postulated in each category of dentist characteristics and beta vectors were estimated by multiple regression. The best predictors formed a significant model (p = 0.000) which explained 26 per cent of the variance.

The effects of patient-initiated phone confirmation strategies on appointment keeping at a hospital dental clinic.

This research reports the effectiveness of three interventions utilized to reduce broken appointments at a hospital dental clinic. Subjects in this study were 306 outpatients receiving dental care at Harborview Medical Center in Seattle. Prior to this investigation the clinic was not using any confirmation strategy; the no show rate was 30.2 percent (N=169). The first intervention was the traditional clinic-initiated phone reminder one day prior to the appointment; the second intervention made use of a mailed reminder, requesting patient-initiated confirmation by phone; and the third gave the same postcard reminder to the patient at the appointment desk, also requesting telephone confirmation. The two patient-initiated strategies were considered more consistent than the traditional phone reminders with the concept of patient responsibility for his own health care. The broken appointment rate for the phone reminder group was 23.5 percent, while for the postcard and the appointment card groups, the rates were 21.2 percent and 11.5 percent respectively. The rate for the appointment card group differed significantly from the phone reminder group and also from the baseline sample.

Chronic reversible cerebral ischemia: evaluation of a new baboon model.

The authors describe their experience with a baboon model of reversible cerebral ischemia. Middle cerebral artery occlusion was achieved by external compression with an implantable, inflatable balloon cuff in awake, unanesthetized baboons. Selective cerebral angiography confirmed consistent, reliable occlusion. Computed tomography demonstrated early density changes after ischemia, which were reversible with reperfusion. Neurological evaluation demonstrated a "recruitment response" of increasingly persistent deficit with repeated occlusion. Permanent deficits were noted after extensive angiography during periods of occlusion. This was accompanied by the dropout of small vessels in the middle cerebral artery distribution. The results of pathological examinations were consistent with the clinical examinations. No gross or microscopic changes were noted after repeated occlusions that caused deficits like those of transient ischemic attacks. Consistent infarctions were noted in animals with permanent deficits after permanent occlusion or after repeated occlusion and extensive angiography.
