Vocês que foram meus professores de graduação e pós-graduação. Responsáveis pelo surgimento da minha paixão pela Ortodontia. Agradeço infinitamente por todas as oportunidades a mim concedidas e por todos os ensinamentos transmitidos.
The consent of patient before the beginning of any procedure has to be a respected condition, without any exception. It is necessary the patients to be aware of their health status, their specific needs, the intention of each treatment, the alternatives plans (including no treatment), to know their prognostic, risks, consequences, limitations, and to be aware of their responsibilities and those of your dentist, resulting in the success of the treatment. The Informed Consent (TCLE) aims to fortify and to clarify the position of the patient, being established the rights and duties of both parts - patient and professional. The integral knowledge of the treatment will minimize the anxiety of the patient and treatment complications, and promote greater quality of dental services and improve the satisfaction of both dentist and patient. However, there are few articles in Brazil about this, but there are some ethics problems involving dental clinics regarding this document of information for the patient. Therefore, the aim of this work is to carry through a critical revision on the subject demonstrating the importance of the TCLE in the Brazilian dental clinics.
Objective: The purpose of this study was to evaluate the influence of the inter-radicular septum width in the insertion site of self-drilling mini-implants on the stability degree of these anchorage devices. Methods: The sample consisted of 40 mini-implants inserted in the inter-radicular septum between maxillary second premolars and first molars in 21 patients to provide skeletal anchorage for anterior retraction. The post-surgical radiographs were used to measure the septum width in the insertion site (ISW). In this regard, the mini-implants were divided in two groups: group 1 (critical areas, ISW≤3 mm) and group 2 (non-critical areas, ISW>3 mm). The degree of mobility (DM) was monthly quantified to determine mini-implant stability, and the success rate of these devices was calculated. This study also evaluated the sensitivity degree during miniscrew load, amount of plaque around the miniscrew, insertion height, and total evaluation period. Results: The results showed no significant difference in mobility degree and success rate between groups 1 and 2. The total success rate found was 90% and no variable was associated with the miniscrew failure. Nevertheless, the results showed that greater patient sensitivity degree was associated to the mini-implant mobility and the failure of these anchorage devices happened in a short time after their insertion. Conclusion: Septum width in the insertion site did not influence the self-drilling miniimplant stability evaluated in this study.

The aims of this study were to assess the effect of a homeopathic agent (Mercúrios Corrosivos 6 CH) and a non-steroidal antiinflammatory drug (nimesulide) on the progression of the alveolar bone loss in experimentally induced periodontitis in rats. Sixty (60) Wistar rats were divided into group 1 (homeopathy), group 2 (nimesulide) and group 3 (saline solution). Silk ligatures were placed at the gingival margin level of the lower right first molar of all rats. Alveolar bone loss was evaluated and analyzed using software Image J. The results were submitted to the analysis of variance (ANOVA) and Tukey's posttest (p<0.05). The analysis revealed that there was a higher bone loss in diseased sites as compared with healthy sites. A significant reduction in the alveolar bone resorption was observed in group 2 (nimesulide) as compared with groups 1 (homeopathy) and 3 (control), 7 days after the induction of periodontal disease. Our data provided evidence that homeopathy does not decrease alveolar bone loss as opposed to nimesulide in experimentally induced periodontitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
