An orthodontic information package designed to increase patient awareness

BACKGROUND: Most patients and their parents experience difficulty in fully appreciating the implications and demands of orthodontic treatment. This is largely because of inadequate understanding of the process of treatment or the commitment required. OBJECTIVES: To determine if a specifically developed video information package could significantly increase patient awareness of the implications of a full course of orthodontic treatment. Changes in attitude to orthodontic treatment after viewing the package were also measured. METHODS: Year 7 (12 year-old) students in two primary schools in the City of Gold Coast, Australia were randomly allocated to either a study group or a control group. Knowledge of and attitude to orthodontic treatment were measured with self-administered questionnaires before and after viewing the information package. RESULTS: The intervention group showed a 15 per cent gain in knowledge (p < 0.001). There was no gain in knowledge for the 45 students in the control group. There was no measured change in perception of need for orthodontic treatment in the study group. There was, however, an increase in potential compliance and positive attitude to the appearance of orthodontic appliances. There was a small increase in willingness to undertake treatment, but this was not statistically significant. CONCLUSIONS: The information package developed for this study increased awareness of the implications and practical difficulties which may be encountered during a course of orthodontic treatment, and produced some changes in attitude to treatment.

Serum antibodies to oral anaerobic bacteria in patients with rheumatoid arthritis

BACKGROUND: This study was conducted to determine the component that causes the disease in rheumatoid arthritis (RA), which shows great resemblance to periodontitis in a pathologic context. MATERIALS AND METHODS: Within this study, the pathogen-specific IgG levels formed against Porphyromonas gingivalis FDC 381, Prevotella melaninogenica ATCC 25845, Actinobacillus actinomycetemcomitans Y4, Bacteroides forsythus ATCC 43047, and Prevotella intermedia 25611 oral bacteria were researched from the blood serum samples of 30 RA patients and 20 healthy controls with the enzyme-linked immunosorbent assay (ELISA) method. RESULTS: The IgG levels of P gingivalis, P intermedia, P melaninogenica, and B forsythus were found to be significantly higher in RA patients when compared with those of the controls. Of the other bacteria antibodies, A actinomycetemcomitans was not found at greater levels in RA serum samples in comparison with the healthy samples. CONCLUSION: The antibodies formed against P gingivalis, P intermedia, P melaninogenica, and B forsythus could be important to the etiopathogenesis of RA.
