Prevalence and reasons for tooth loss in a sample from a dental clinic in Brazil

Purpose. To evaluate the prevalence and reasons for teeth extractions in a sample from a dental clinic in Brazil. Methods. The prevalence of teeth mortality was analyzed by gender, age, tooth type and reasons for extraction on 800 teeth of 439 subjects, whose data was collected in clinical records in a convenience sample. Results. The groups with range from 35 to 44 years, 45 to 54 years and 55 to 64 years revealed significantly greater number of teeth extractions than other age groups (P < 0.0001). The anterior teeth loss increased significantly with aging, while the tooth mortality of premolar and molar were higher in younger people. The caries was the more prevalent reason for tooth mortality among young and adults up to 44 years old, while the periodontal disease was the main reason for extractions from 45 years old until range of 81 years (P < 0.0001). Conclusions. It can be suggested that some reasons for tooth loss were age-dependent, but the caries and the periodontal diseases were the main reasons for tooth mortality in this Brazilian sample.

Because someone has recommended it - Patients’ reasons for choosing acupuncture or qigong

Question: Recent research has indicated a considerable contribution of placebo effects to the outcome of acupuncture treatments: especially patients’ expectations seem to have an influence [1] and [2]. In this context it is important to better understand the patient–practitioner relationship. The aim of this study was to investigate why patients in Switzerland choose acupuncture or qigong, and what they expect from the treatment and the practitioners [3]. Methods: A qualitative survey with open questions was performed among 38 patients newly enrolled for treatment in 7 different practices for Traditional Chinese Medicine ((TCM); 6 practices for acupuncture, 1 for qigong). Questions aimed to identify reasons for choosing TCM, knowledge about its range of indications, and patients’ expectations towards method and therapist. Answers were categorised and analysed by frequency. Results: The most common reasons for choosing TCM were recommendation by acquaintances, the idea of trying a new treatment and the perception of TCM as being a gentle method. The majority of respondents had poor knowledge about the range of conditions to be treated with TCM: pain of the musculoskeletal system, headaches and chronic problems were considered as main indications. Surprisingly, gynaecological or gastro-intestinal diseases were not mentioned by the respondents. Practitioners were expected to have professional competence, provide information, empathy and understanding. Conclusions: The most striking result of this survey was the fact that patients knew very little about TCM and its indications. Thus, more precise information about TCM and other complementary methods should be offered to the general public, which would help patients to decide whether to consider TCM for the treatment of their disease. And, on the other hand, for the therapists it is important to better understand and respond to patients’ expectations in order to achieve better treatment results. The results of this qualitative survey were briefly discussed with the participating practitioners, who found them remarkable and support further quantitative studies. We plan to further investigate this topic. References 1. J. Pariente, P. White, R.S.J. Frackowiak, G. Lewith. Neuroimage, 25 (2005), pp. 1161–1167 2. M. Karst, D. Schneidewind, D. Scheinichen.

Reasons for ordering computed tomography scans of the head in patients with minor brain injury

Minor brain injury is a frequent condition. Validated clinical decision rules can help in deciding whether a computed tomogram (CT) of the head is required. We hypothesized that institutional guidelines are not frequently used, and that psychological factors are a common reason for ordering an unnecessary CT.
