A prospective Saudi dental stem-cell bank from the perspective of the public and dental practitioners: A cross sectional survey

OBJECTIVES: The aim of this study (1) To evaluate the Saudi public's knowledge and attitude on dental stem cells (DSC) for therapeutic/banking purposes, (2) To evaluate the perception of Saudi dentists towards DSC and their attitude towards banking of DSC. METHODOLOGY: This was a cross-sectional study based on an electronic survey distributed through the social media nationwide among the Saudi public, and through paper-based surveys among dentists in Riyadh. By convenience, eligible study participants were Saudi adults from the community and dentists from 17 dental centers in different regions of Riyadh. Using SPSS v. 25, descriptive statistics (n,%; PMS ± SD) and bivariate analyses (Pearson's Chi square, Mann Whitney) were conducted to determine factors associated with the study outcomes, with a P value statistically significant at <0.05. RESULTS: For the Saudi public, 1494 participants completed the survey. The PMS ± SD of public knowledge was 25.5 ± 25.9, while their attitude was 80.2 ± 27.0. Factors associated with higher knowledge scores were younger age groups, while female participants, older age groups, university educated and employed participants had higher attitude. For Saudi dentists, 246/262 (94%) dentists responded to the questionnaire. Their PMS ± SD of perception towards DSC research for regenerative purposes was 74.5 ± 15.6. Factors associated with higher perception scores were those with more experience. Dentists who had higher perception scores towards DSCs were significantly more willing to save teeth for regenerative dental treatment. CONCLUSION: The Saudi public community had poor knowledge about the therapeutic and research benefits of DSC, yet high degree of attitude to enroll in a future Saudi DSC bank. Saudi dentists had moderately high levels of perception towards DSC research.
