Awareness, attitude and practice regarding disinfection and handling of extracted teeth among the students in a dental college in India

Abstract

Objective:The main objective of this study is to assess about the awareness, attitude, and practice regarding disinfection and handling of extracted teeth among the students of a dental college in Odisha, India.Materials and Methods:The survey was done with a self-designed questionnaire distributed among the students of a dental college in Odisha, India. Data analysis was done using the Statistical Package for the Social Sciences Software (SPSS for Windows, Version 16.0., Released 2007, Chicago, SPSS Inc.) and the results obtained.Results:Of the many methods available, the safest and practical methods to sterilize and disinfect the extracted human teeth could be autoclaving, submersion in 10% formalin and 5.25% sodium hypochlorite solutions. In addition, it was found that there is a significant need to educate the potential handlers of such extracted teeth about the latest statuary protocol and guidelines.Conclusion:Most of the participants in the study were aware of the established safety protocols regarding how to handle the pathogenic specimens and were putting in practice those standardized guidelines. But still another good number of handlers need to change their casual attitude while following the safety guidelines so as to protect themselves, others and the environment from the pathogenic clinical specimens.

Knowledge, Attitude and Practices (KAP) of Sterilization and Disinfection of Health Care Professionals in Bangladesh

“…In our study, among the health care professionals, the majority 27 (33.33%) were Sanitary Staff, 23 (28.39%) Nurse, 16 (19.75%), Lab Technicians and 15 (18.5% were Interns. Similar observation was observed in some other studies [8][9][10]. In our study, it was observed among the 81 health care professionals, 65 (80.20%) had knowledge on Sterilization methods & its harmful effects whereas 16 (17.80%) had no knowledge regarding sterilization methods and its harmful effects and followed by 56 (69.10%) had knowledge on disinfection methods & its harmful effects, 25 (30.90%) had no knowledge, 69 (85.20%) had knowledge on post sterilization management of surgical instruments and 12 (14.80%) had no knowledge, 58 (71.60%) had knowledge on temperature for sterilization in autoclave while 23 (28.40%) had no knowledge, 61 (75.30%) had knowledge on management method of biomedical waste whereas 20 (24.70%) had no knowledge, 72 (88.90%) had knowledge on Sterilization protocol/policy in their hospital whereas 9 (11.10%) had no knowledge and 67 (82.70%) had knowledge on infection prevention and control policy in their hospital and 14 (17.30%) had no knowledge on infection prevention and control policy.…”

Biobanco de dentes da UFPR: Relato de 12 anos

“…Assim, anteriormente aos anos 90, a quantidade de dentes extraídos era descartada ou guardada em coleções particulares por cirurgiões-dentistas e, assim, não se tinha material dentário com origens definidas e documentadas para uso em atividades didáticas e de pesquisas na Odontologia (Medeiros et al, 2020). Desse modo, para obtenção dos dentes, requeridos e utilizados em diversas disciplinas, tais como endodontia, anatomia dental, dentística e prótese (Freitas et al, 2012;Pereira, 2012;Endo et al, 2017;Sethi et al, 2018), praticava-se o comércio ilegal de dentes (Miranda & Bueno, 2012;Pereira, 2012;Valadas et al, 2019;Medeiros et al, 2020;Vishwanathaiah et al, 2022).…”

“…O comércio de dentes e uso de elementos dentários sem procedência comprovada fere princípios éticos e legais, caracterizando um crime, visto que os dentes são considerados órgãos pela Lei n° 9.434 de 04/02/1997 (Lei de Transplantes Brasileira), além de que, ao entrar em contato ou manipular estes dentes extraídos, temse o risco de contaminação cruzada, visto que são considerados fonte de patógenos e materiais de alto risco biológico (Nassif et al, 2003;Pinto et al, 2009;Freitas et al, 2012;Miranda & Bueno, 2012;Pereira, 2012;Machado & Garrido, 2014;Endo et al, 2017;;Sethi et al, 2018;Valadas et al, 2019;Medeiros et al, 2020;Vishwanathaiah et al, 2022). Logo, a existência de um local responsável pela captação, processamento e armazenamento de dentes em universidades é fundamental (Medeiros et al, 2020;Gebauer et al, 2021;Vishwanathaiah et al, 2022).…”

Obtaining human teeth for dental education: A cross‐sectional study to create ethical and transparent processes

“…1,2 In dental teaching, human teeth have been used to allow students to experience the anatomy of the root canal system, the natural hardness of healthy and decayed tissues, to learn the basics of cavity preparations, and prosthodontic techniques. 3,4 Research in dentistry carries out numerous in vitro studies to evaluate the physical, chemical, and biological characteristics of various materials and of the dental tissues themselves in order to implement results into dental practice. [5][6][7] With changes in lifestyle and disease patterns, and alternative treatments which result in patients retaining their teeth for longer periods of time, suitable extracted teeth for learning and teaching purposes are being diminished.…”
