Gingivo-mucosal and cutaneous reactions to amalgam fillings.

BACKGROUND: A number of reports exist on the side effects of materials used to restore teeth. Most of the cases involve local allergy reactions, but also skin lesions are described. Few cases are described where both local effects on the mucosa and skin lesions distant to the oral cavity are caused by amalgam. RESULT: The case presented indicates that the release of mercury from amalgam fillings is able to induce hypersensitivity reactions resulting in soft-tissue changes in the gingiva, buccal mucosa, tongue and on the skin of the back of the hands.

Re-treatment profiles during long-term maintenance therapy in a periodontal practice in Norway.

BACKGROUND: Periodontal therapy coupled with active maintenance has been shown to be effective in maintaining periodontal health, however, the question of re-treatment is rarely alluded to in the literature. AIM: To quantify the type and extent of re-treatment in a group of patients who had completed a definitive course of periodontal treatment in a Norwegian specialist periodontal practice. The study also investigated factors associated with the provision of periodontal surgery as a re-treatment modality. METHODS: A consecutive group of patients who had comprehensive periodontal treatment, which included periodontal surgery, and were subsequently maintained for between 10 and 17 years were studied. RESULTS: One hundred and one patients with an average age at reassessment of 59.4 (standard deviation (SD) 9.0) years were studied. The average length of the review period was 13.1 (SD 1.9) years. In addition to routine maintenance, 50 patients had further re-treatment and 40 of those who were re-treated had periodontal surgery in the study period. Logistic regression showed that independent predictors of surgical re-treatment, with the effects adjusted for other variables in the model, were uncertain or poor prognosis at baseline, erratic or poor post baseline compliance and a family history of periodontal disease. CONCLUSION: Considerable amounts of re-treatment, including in many cases extensive non-surgical treatment or periodontal surgery, were provided for patients who had surgical periodontal treatment and were subsequently maintained for least 10 years in a specialist periodontal practice.

Research in a dental practice setting.

There is a shortage of research from dental practice. The aim of this article is to stimulate more interest in dental research. This is done by explaining the basic principles of doing research in a dental practice setting. Examples are taken from the author's own practice. Emphasis is placed on the following points: how to develop and research ideas; factors specific to dental practice; how articles and journals are rated; making a protocol for the study; examiners' reliability and statistical analysis.

Compliance in a Norwegian periodontal practice.

PURPOSE: Patients' compliance with periodontal maintenance therapy is important for the treatment outcomes, however, most studies report compliance rates ranging from only 11%-45%. The aims of this study were to report on the acceptance of proposed treatment and the long-term compliance of patients treated in a specialist periodontal office in Norway. This was part of an internal quality control measure for this practice. MATERIALS AND METHODS: 152 consecutive patients who completed periodontal therapy in 1988 were retrospectively assessed after 10 years. In addition, the case records of 624 consecutive patients referred for periodontal assessment between 1989 and 1993 were examined to determine how many decided to accept the proposed therapy. RESULTS: The majority 132 (87%) of those who completed treatment in 1988 had attended for the prescribed maintenance therapy over a ten-year period. It was not possible to detect any differences between the compliers and non-compliers in terms of age, gender, severity of disease, cost and national insurance coverage. The 152 patients were originally referred by 18 general dental practitioners. The 'high referring' dentists (>8 referrals) had significantly more non-complying patients than dentists who made less than 7 referrals. 20 (3%) of the 624 periodontal referrals over a 5-year period chose not to proceed with the proposed therapy. CONCLUSION: There was a high level of patient compliance in the population group studied in this specialist periodontal practice. Geographic and cultural factors as well as a stable rural population may be important factors in the high level of compliance with maintenance therapy in this practice. The referring general dental practitioners may also play an important role in patient compliance.

Patient perceptions of periodontal therapy completed in a periodontal practice.

BACKGROUND: The perceptions that patients have of periodontal therapy have not been extensively studied and are not well understood. The purpose of this study was to assess the degree of discomfort associated with periodontal therapy carried out in a specialist practice. METHODS: A consecutive group of 150 patients (90 females, 60 males; mean age 54.5 years) who had completed periodontal therapy, which included surgery, in a periodontal practice in Norway was studied. The patients indicated the discomfort they had experienced with periodontal therapy on a visual analog scale (VAS). Other factors associated with postoperative discomfort such as the use of analgesics were recorded. RESULTS: The mean VAS scores were low for all procedures investigated. The highest mean score was recorded for anesthesia in the upper anterior region. There were small differences between the levels of discomfort reported by males compared to females. The VAS scores decreased with increasing age for anesthesia in the lower arch (P = 0.004) and surgery in the lower arch (P = 0.003). Virtually all (97%) of the patients perceived periodontal treatment to be associated with no more discomfort than conventional dental treatment. CONCLUSIONS: Very low reported levels of discomfort were associated with both non-surgical and surgical periodontal therapy by Norwegian patients treated in a specialist periodontal practice.
