https://www.selleckchem.com/products/nd-630.html The removal of tissues affected by caries lesions is one of the most frequent procedures in daily dental practice. The aim of this study was to collect information about the habits of members of the academic and non-academic dental community in Argentina regarding the use and conditioning of burs employed in the removal of dentin during the treatment of carious lesions. A 14- item questionnaire was prepared, and once validated in small groups, it was sent to three lists of dental subscribers through the computer services area of the School of Dentistry, University of Buenos Aires, Argentina (FOUBA). By the deadline for receiving responses, which was set as four weeks after the sending date, 294 replies were received. Results percentage (95%CI) 47.93% (42.18-53.68%) of the respondents were faculty members, of whom 37.24% (31.68-42.81%) claimed to belong to FOUBA. Of the respondents, 26.90% (21.79-32.00%) reported being under 35 years old, 37.59% (32.01-43.16%) 36 to 45 years old, 22.07% (17.30-26.84%) 46 to 55 respondents state that they sterilize their rotary instruments in some way after use. About half of them do not keep track of the number of uses and use burs "until they no longer cut".In this study, comprehensive clinics (CC) are interpreted as a pragmatic projection of the complexity of health. The aim of the study was to analyze the characteristics of the CCs at different schools of dentistry in Argentina. Data were collected from document analysis and interviews with key respondents at 8 universities, classified according to the criteria of Bray and Thomas. Interviews were developed and analyzed according to discourse analysis. The convergences and divergences among curricula were established and analyzed statistically. Triangulation of results showed that (a) Most curricula (7/8) included subjects called CC; (b) the permanence of CCs in the curricula was not stable, with changes recorded in different periods
