Effects of repeated dental health care education on gingival health, knowledge, attitude, behavior and perception.

To evaluate the effect of repeated dental health care instructions plus a single initial prophylaxis a study was conducted in the Dutch Royal Military Academy. The experimental group consisted of second year cadets and the control group of first year students. The final examination took place 1 year after the baseline examination. After the final examination the study was repeated to see whether the results of the first experiment were reproducible. Experimental effects were measured by a questionnaire and dental indices. The results of the study showed significant and relevant improvements in dental knowledge, attitude, reported behavior, the participants' perception of the gingival status, the ability to diagnose gingivitis and the condition of the supporting tissues. The effects were reproduced in the second experiment.

Dental knowledge, attitude and behavior in 12-year-old Dutch suburban children.

A questionnaire on dental knowledge, attitude and behavior was presented to Dutch suburban children in the 6th grade (n = 399). The mean age was 12.3 years. The children scored relatively high on knowledge and attitude. Girls scored better on knowledge and attitude than boys. However, the differences were small. Between socioeconomic classes no differences were found in knowledge scores. The attitude of the higher socioeconomic classes was more positive than that of the lower classes. With regard to behavior more than 90% of the children reported that they have their own toothbrush, use toothpaste containing fluoride and visit the dentist every 6 months. Further it was found that 69% eat sweets several times a day, 53% offer sweets in school when they celebrate their birthday, 28% brush their teeth less than twice a day, 45% sometimes forget to brush their teeth and 44% use fluoride tablets. No clear differences in behavior between boys and girls were found. The higher the socioeconomic class of the children the higher the toothbrushing frequency, the more fluoride tablets are used and the lower the sweet consumption frequency. Although almost all children stated that their parents consider toothbrushing important, 24% were not supervised. It is also suggested that effectiveness of dental health education on behavior should not be evaluated in short term studies.

Effect of dental health care instruction and prophylaxis on knowledge, attitude and behavior in Dutch military personnel.

A study was conducted to evaluate the effect of a single dental health care instruction and prophylaxis on knowledge, attitude and behavior. Ninety-six army recruits from two military camps were randomly allocated to four groups: a control group, a group that received an oral prophylaxis, a group that received a single dental health care instruction, and a group that had both prophylaxis and dental health care instruction. Treatment effects were measured by a questionnaire 1 month and 3 months after the instruction. A single dental health care instruction improved knowledge, and some areas of behavior. The improvement in attitude was not clear. The improvements were small and showed a tendency to diminish after 1 month.

Effect of a single dental health care instruction and prophylaxis on gingivitis.

This study was conducted to evaluate the effect of a single dental health instruction on gingivitis in an adult population. Ninety-eight army recruits from two military camps were randomly allocated to four groups: a control group, a group that received a professional prophylaxis, a group that received dental health care instruction and a group that had both a prophylaxis and dental health care instruction. Treatment effects were measured 1 week, 1 month and 3 months after the initial examinations. The single prophylaxis resulted in a small temporary improvement. The effect of the single dental health care instruction was also small, but lasted until the end of the trial. A single instruction plus prophylaxis resulted in the clearest improvement, which was still present after 3 months. It can be concluded that any single treatment should at least consist of dental health care instruction plus a prophylaxis.

Time utilization, productivity and costs of solo and extended duty auxiliary dental practice.

A study was conducted to compare the time utilization of the dentist, and productivity and costs for solo (one dentist, one chairside assistant and one treatment room) and extended duty settings (one dentist, two extended duty dental hygienists, one chairside assistant and two treatment rooms). Only amalgam and composite restorations done in a general group practice were included. In the extended duty setting the dentist spent more time in managerial activities and less time in treatment than in the solo setting. Nevertheless, the dentist in the extended duty setting produced 53% more restorations as compared with solo practice. The cost ratio of solo to extended duty practice was computed to 1:1.52. From the point of view of microeconomics, the extended duty setting was found no worse than the solo setting.

Neurofibromatosis and reticulate acropigmentation of Dohi: a case report.

A 13-year-old boy had progressive pigmentary changes affecting his limbs which began when he was 9 months of age. He also had a history of café au lait macules on his trunk since birth which were becoming more numerous. The diagnosis of reticulate acropigmentation of Dohi (dyschromatosis symmetrica hereditaria) and neurofibromatosis type 1 (NF-1) was made on the basis of the clinical features. To our knowledge, this is the first report of these two conditions occurring in the same patient.

Multiple pains and psychosocial functioning/psychologic distress in TMD patients.

PURPOSE: This study assessed multiple pain conditions and their association with psychosocial functioning, psychologic distress, and somatization in patients with temporomandibular disorders (TMD) based on RDC/TMD Axis II findings. Nonspecific pain items examined included headaches, heart/chest pain, lower back pain, nausea/abdominal pain, and muscle pain. MATERIALS AND METHODS: In this study, 202 TMD patients (58 men and 144 women) referred to two TMD clinics participated. The mean age of the predominantly Chinese patient population (82%) was 32.6 years (range 13 to 65). The RDC/TMD history questionnaire was input directly into computers by patients. Graded chronic pain and SCL-90 scales were generated online and automatically archived for statistical analysis. Data were subjected to Spearman's rank-order correlation and Kruskal-Wallis and Mann-Whitney tests at a significance level of .05. RESULTS: Of the patients, 43% were moderately to extremely distressed by headaches. The percentage of patients who were distressed by heart/chest pain (7%), lower back pain (26%), nausea/abdominal pain (17%) and soreness of muscles (22%) was lower. Of the TMD patients, 16% experienced more than three pain items. Significant and positive correlations were observed between number of pain items experienced and graded chronic pain severity, depression, and somatization. Correlation coefficients ranged from .27 to .65 for graded chronic pain scales and somatization (without pain items) scores, respectively. CONCLUSION: Results suggest that the number of nonspecific pain conditions reported may be a predictor of psychosocial dysfunction, depression, and somatization.
