Knowledge and attitude toward dental stem cells among dental professionals: A questionnaire study

Introduction: Dental stem cells (DSCs) derived from tooth structures refer to adult stem cells. DSCs can be used to regenerate both dental tissues and nondental organs. DSC research is progressing at a rapid pace and hence it is imperative for dental professionals to possess adequate knowledge and a favorable attitude toward the same. The aim of this study was to assess the knowledge and attitude of dental professionals toward DSCs. Methodology: A cross-sectional, descriptive, questionnaire-based survey was conducted on a sample of 200 dental professionals from various dental colleges in Chennai. The questionnaire included a total of 15 questions to assess the knowledge and attitude toward DSCs. The Pearson's Chi-square test and percentages of the total were used for statistical analysis. Results: A total of 200 dental professionals completed the questionnaire survey; of which 42 (21%) were male and 158 (78%) were female. Maximum respondents were intern (n = 92, 46%), followed by dental practitioners (DP) (n = 58, 29%) and postgraduates (n = 50, 25%). Around 182 (91%) dental professionals are aware of the term stem cells. Overall, 66% of dental participants were not aware of ethical considerations and guidelines related to DSCs given by the Indian Council of Medical Research. The majority of dental participants (83%) were interested in attending workshop/conference/Continuing Dental Education (CDE) program on applications of stem cells. Conclusion: This study revealed that there was a generalized awareness of the term “DSCs” among the study participants. However, there was a huge lacuna in the knowledge of its types, ethical considerations, and the concept of stem cell banking and DSC banks in India. The results of the current study emphasize the need for improvement in knowledge of DSCs for dental professionals by promoting more CDE programs focusing on this subject.
