Composite resins are restorative materials widely used in dental offices due to their mechanical properties, aesthetics and clinical performance. However, the polymerization shrinkage present in conventional composites is still a major limitation. In this context, resins called bulk-fill, or filling resins, were developed, which have the possibility of inserting a single increment in the dental cavity due to less polymerization shrinkage, better mechanical properties, easy execution, and as a consequence the decrease in clinical time. However, there is still no consensus in the literature regarding the effectiveness and durability of this material. The objective of this study was to carry out a bibliographic review on bulk-fill resins and their comparison with conventional resins. Scientific articles in Portuguese and English from 2002 to 2019 were searched in the databases Medical Publications (PUBMED) and Scientific Eletronic Library Online (SCIELO), with 50 papers selected for full reading based on the inclusion criteria: language in English or Portuguese and publications made in the last twenty years and exclusion criteria: articles that did not address the central theme of the study, publications in languages other than English or Portuguese, electronic articles not available for full reading and periodicals outside the established period. According to the researched bibliography, filling resins are an option of restorative material, which have been showing success similar to that found in rehabilitation with conventional composite resins.

The aging of the population requires the technical preparation of health professionals, making knowledge of the reality of the elderly population, such as oral health conditions, part of their clinical performance. Thus, the Dental Surgeon will be able to plan and execute correct and differentiated actions for this specific population group. The objective of this study was to analyze the scientific publications about the main occurrences found in the intra-buccal examination in the elderly. This work has a qualitative approach, applied nature, with the exploratory objective and bibliographic character, through the research in books, scientific journals, electronic articles, theses and dissertations that deal with the main intraocular pathological occurrences in the elderly, in the Portuguese and English, published in the years 2000 to 2020. It was also consulted literature deemed important for the subject matter, before the inclusion period. The scientific production analyzed showed the main intra-oral occurrences in the elderly population: dental loss, prosthesis use, caries disease, periodontal disease, dental wear, chewing difficulties, oral pain, xerostomia as well as soft tissue lesions of the mouth, which has some impact on the life of this population group, whether physical or psychological.

Objective: To conduct a literature review on prefabricated fiberglass intra root pins. Methodology: A search was performed in the PubMed and Google Scholar databases with the following descriptors: “Post and Core Technique”, “Treatment” and “Dental Restoration Failure”. Results: Among the advantages of prefabricated intra root pins systems, one can highlight the low cost, simplicity of the technique, conservation of the remaining dental structure, elimination of the laboratory phase, and yet, the carbon fiber and glass pins have similar elasticity module that of dentin and similar flexion to that of the tooth, which reduces the risk of fractures when compared to molten metal cores. In addition, fiberglass pins have the advantage of being more translucent, which allows for a greater transmission of light, making them more aesthetic. Conclusion: Fiberglass pins are currently considered the best option for the rehabilitation of teeth treated endodontically with extensive coronary loss, since they have an elasticity module similar to that of dentin, flexion resistance, simplicity of the technique, less clinical time and have superior aesthetics to other intra root pins.

Objetivo: O presente estudo teve como objetivo discorrer sobre a importância do cirurgião dentista em unidades de terapia intensiva para a manutenção da saúde bucal em pacientes sistemicamente comprometidos. Método: Foi realizada uma revisão de literatura com abordagem qualitativa. Foram selecionados artigos científicos indexados nas seguintes bases de dados online: Google Scholar e Pubmed. Os critérios de inclusão foram: artigos com disponibilidade na íntegra, escritos nos idiomas português e inglês, que apresentavam coerência com a temática e com data de publicação entre 2012 e 2020. Resultados: Pacientes internados em unidades de terapia intensiva apresentam comprometimento geral da saúde e, muitas vezes, devido às condições desfavoráveis da cavidade oral, podem desenvolver infecções pulmonares e ou generalizadas. A presença do Cirurgião-Dentista nas equipes interdisciplinares das UTIs colabora para a prevenção de infecções hospitalares, com diminuição do tempo de internação e do uso de medicamentos pelo paciente crítico, contribuindo de forma efetiva para o seu bem estar e dignidade. Conclusão: Os estudos relatam que, embora a presença do cirurgião dentista ainda não esteja consolidada em UTIs e a legislação brasileira apresente ainda lacunas para a inserção deste profissional em UTI, sua importância junto à equipe multiprofissional é indiscutível considerando a simplicidade e a efetividade das medidas que compõem os cuidados em saúde bucal.

Objective: To describe the clinical and histological aspects, as well as to discuss the diagnosis, treatment and preventive measures of actinic cheilitis (AC). Methodology: A literature review was carried out through the collection of articles indexed in the PubMed, Scielo and Regional Portal of the Virtual Health Library databases in the period 2002 to 2020, in addition to books on Oral Pathology and Stomatology. Results: It is important that, in dental practice, the professional is properly trained, especially the dental surgeon, as it is up to him the role of prevention, diagnosis, treatment and preservation of this clinical condition, with the necessary knowledge for this type of disease , because apparently simple lesions can potentially respond to progression to cancer. Conclusion: To prevent AC, the use of wide-brimmed hats and lip balm with sunscreen is recommended. The ideal treatment should be chosen according to the individual situation of each patient, and for acute AC prevention and conservative treatment is the best option, for chronic AC, total removal of the lesion is necessary.
