Oral pathologies or some treatments can cause facial and functional alterations, being fundament to retrieve those functions restoring the original anatomy of the lost tissues. On this purpose, various techniques have been studied, one of these was the tissue engineering. Mesenchymal stem cells (MSC) are multipotent adult stem cells. The MSC in the oral cavity have been striking for regenerative therapies by its high plasticity, good interaction with scaffolds and growth factors, good proliferation and differentiation, they are also easy to obtain. Objective The objective of this study was to describe the current uses of the intraoral MSC for the regeneration of the tissues of the oral cavity. An electronic research was made in the databases PubMed, Cochrane Library, Google Scholar, Scopus and EBSCO between 2000 to 2018. 21 articles were included. 13 were studies in vivo and 8 were studies in humans. The site mostly used as a giver site was the dental pulp. Intraoral MSC are able to regenerate the pulp dentin complex, alveolar bone and periodontium. Intraoral MSC come from easy access areas, less traumatic interventions and have high potential to regenerate intraoral tissues in comparison to MSC from other sites of the body which allows a more predictable oral tissues regeneration.

Key wordsOral stem cells, oral cavity, regeneration, tissue engineering. Over the last few years, there has been a great advance in regenerative medicine, with various studies that have observed the ability to repair or regenerate dysfunctional tissues with the patient's own cells, such as with mesenchymal cells. In this area, mesenchymal stem cells (MSCs) from the oral cavity have attracted attention because of their easy access and multiple cellular differentiations. Multiple studies have shown the various clinical applications at the intraoral level, especially at the level of bone regeneration, but the potential applications of oral MSC at a systemic level have been scarcely described. Objective The objective of this review was to describe the potential therapeutic uses of intraoral MSCs in other tissues of the organism. A review of the literature between 2000 and 2019. Only included those studies done on animals or humans. Twenty five articles were selected, all performed on animals. The donor site most used were the temporary teeth exfoliated from humans, representing egenerative medicine, dental component. To date, the quality of the Internet information regarding the control and management of 2019-nCov virus transmission in dental clinics has not been evaluated. The aim of this study was to evaluate the quality of Internet information about the control of 2019-nCov transmission in dental practice. Internet websites were identified daily using two search engines Google and Yahoo! during the week from 20-06-2020 to 26-06-2020, applying the search term "2019-nCov transmission control in dental practice." The first 100 consecutive sites identified in each search were visited and classified. The quality of information contained in each website was analyzed using the Journal of the American Medical Association (JAMA) benchmarks, whether the website had been granted the Health on the Net Foundation Code of Conduct (HONcode), and a new tool for evaluating the quality of Internet websites providing information relating to 2019-nCov transmission control in dental practice, which awards a score of 0-40 points (8-13 pernet, quality of information. Retrospectively to evaluate the influence of radiochemotherapy (RCT) in the treatment of surgically and non-surgically treated Oral Squamous Cell Carcinoma (OSCC). We analysed 934 patients treated in Hospital Haroldo Juaçaba (2000-2014; 15 years of study) by extraction of data type of cancer, localization of tumour, sex, age, race, education level, risk factors (smoking and alcohol use), year of diagnosis, TNM stage, therapeutic approach, health system used (public or private) and overall survival (OS). Surgically and non-surgically treated OSCC were compared by chi-square and Fisher's exact tests, and their prognostic factors were analysed by log-rank Mantel-Cox plus Cox regression tests (SPSS 20.0, <0.05). Non-surgically treated OSCC patients had a lower OS than surgically treated OSCC patients ( <0.001), but an increase in OS was shown in both groups. Although the 2010-2014 period ( =0.003), education level ( =0.032), tongue/mouth floor/palate localization ( =0.023) and TNM stage ( <0.05) were important in non-surgically treated OSCC OS, the major prognostic factors were node metastasis ( =0.003) and non-use of RCT ( =0.039) (multivariate analysis). In surgically treated OSCC patients, higher OS was shown in the 2010-2014 period ( <0.001), females ( =0.012), non-drinkers ( =0.011), non-smokers ( =0.009) and those with lower TNM stage ( <0.05), but the major prognostic factor was the 2010-2014 period ( =0.004) (multivariate analysis), which was directly associated with an increase in RCT indication ( <0.001). The increase in RCT improved the OS in this large cohort of surgically and non-surgically treated OSCC patients. Mouth neoplasms, neck, radiotherapy, drug therapy, combination.

Heat generation during osteotomy site preparation is a crucial factor that determines the success of dental implant placement. Among the factors that affect the heat generation, drilling speed, hand pressure and coolant temperature are independent variables. However, a relation between these three parameters and their optimal values required for the maximum outcome has not been studied so far. This study aims at finding out a relation between these factors in order to derive the optimum balance required, using an study. This experiment was performed on bovine femur. https://www.selleckchem.com/products/gs-9973.html A total of 72 drillings were undertaken with the aid of a physiodispenser mounted on the test apparatus. Drill diameters of 2 mm and 2.8 mm, rotated at 1500, 2000 and 2500 rpm were included for the analysis. Hand pressures included for the comparison were 1.2 kgf and 2.4 kgf. Normal saline at room temperature, and that chilled to 00C were used for external irrigation. The temperature generated during drilling was recorded by infrared thermography using a Forward-Looking Infrared (FLIR) camera.
