O uso do beta-tricálcio fosfato como substituto ósseo em odontologia

The correction of bone defects is the restoration of lost structures which can be replaced by alloplastic implants or bone grafts. Due to the known disadvantages of removal of autogenous grafts, most researches in dentistry aim to develop alloplastic or non-alloplastic materials able to replace bone without these limitations. Beta-Tricalcium Phosphate (β-TCP) is a synthetic granular bone substitute, biocompatible, osteoconductive, which can be used in the alveolar reconstruction. In this work, we perform a literature review on the β-TCP characteristics and discuss its application in dentistry.

Imageologia na odontologia e aspectos legais

The technology, through the advent of new equipments that allow imaging exams, has helped very much in the diagnosis and prognosis of diseases in Dentistry. The use of informatics, in general, in the manufacture of clinical reports is increasingly present in the dental offices. The legal validity of these systems is questioned, and is matter of discussion. This work makes considerations about Imageology or Diagnostic by image, a new area that is appearing on Dentistry. Among other exams, there are: digital radiography, tomography, computed tomography, artomography, magnetic resonance, computed cefalometry and ultra-sonography. It permits the professional to obtain a better diagnostic, and to the patient, the visualization of his problem and treatment. A survey on the possibilities of using informatics in Dentistry, particularly in Radiology, was also carried out, as well as the legal aspects, which are in accordance with the Law 8.935/94, what guarantees its practicability. Digital Certification is a mechanism that provides legal validity to documents and, as such, to radiographic images and others. It is a procedure that the dentist should take to ensure that he/she has safeguarded the judicial proofs that may be necessary in an eventual demand.

Métodos de avaliação de risco de desordens músculo-esqueléticas nos membros superiores voltados para a odontologia

The dental professionals are exposed to many risks of development of occupational diseases and the musculoskeletal disorders in the upper limbs are the most common disease. This problem may result in lower productivity and / or early retirement. Therefore, early diagnosis should be done through a reliable and valid system of risk assessment. Because of that, this study set out to conduct a review of the literature on methods of risk assessment of musculoskeletal disorders in the upper limbs in dental professionals. Conclusion: It was concluded that the available methods for assessing the risk of musculoskeletal disorders in dentistry are self-reports, observational and direct. Among these methods, the self-reports were frequently used to detect the risk of musculoskeletal disorders among dentists, dental students and professionals from the dental team. Further studies should be performed in dentistry using observational and direct methods.

Dificuldades relatadas por estudantes de odontologia diante de procedimentos relacionados à periodontia

Objective: This study aimed at evaluating the difficulties reported by last-year dentistry course students regarding basic and surgical periodontal procedures. Methods: A proposed questionnaire with 24 questions, 14 related to basic periodontal procedures and 10 to surgical procedures, was applied to 45 undergraduate students with jobs involving these procedures, during the practical activities of the Integrated Clinic Discipline, a compulsory subject in the curriculum of the course, taught to last-year students. Students were asked about their own perceptions of the difficulties in implementing the various steps related to the treatments. The degree of individual difficulty was determined according to the Likert scale: 0 = none, 1 = mild, 2 = moderate, 3 = high, 4 = very high. Exploratory analysis of data was applied, and the difficulty level was also dichotomized into none to mild (scores 0 and 1) and moderate to very high (scores 2–4). Results: Regarding the basic periodontal treatment, bone level probing was the procedure with the highest number of student difficulties (57.5%). As for the difficulties reported by students regarding the stages of periodontal surgery, only the procedures related to anesthesia and suture removal had no report of doubts. Conclusion: Periodontal surgery was the procedure involving the most prevalent questions reported as moderate to very high, and the indication for the most suitable surgical technique was the stage with the highest percentage of questions (66.6%) among the undergraduates.

Extensão universitária e trabalho voluntário na formação do acadêmico em odontologia

The aim of the present study was to point out the importance of the experience of undergraduate dental students in extra-curricular activities and volunteer work, as a means through which to gain essential knowledge and abilities for their professional lives. A literature review of the Medline, Scielo, and Lilacs databases was carried out in an attempt to select articles related to the university extension and volunteer work of undergraduate dental students. It is still extremely difficult to include university extension and volunteer work as an important activity in Dentistry courses. However, the presentday work market demands professionals who have expertise not only in dental techniques, but also in the socio-cultural characteristics of communities, considering that people need to be comprehensive in their psychosocial aspects in order to be treated as a complete professional. Therefore, university dentistry courses should give equal consideration to both oral rehabilitation skills and the promotion of general healthcare, acquired mainly through extracurricular activities, in an attempt to redeem the integral education of the healthcare professional. Moreover, students should pay closer attention to the opportunities offered during their undergraduate courses, as the work market for dentists is becoming more and more competitive. Moreover, the dentist whose professional life is limited to the dental office will most certainly forgo the opportunity to act in other social areas as well as the recognition that comes with such acts.
