Flexible Removable Partial Dentures: Insights into Knowledge, Attitudes, and Practices of Dentists in Tunisia

Abstract This article aims to assess and analyze the knowledge, attitudes, and practices of Tunisian dentists regarding flexible removable partial dentures (RPDs). A cross-sectional study was conducted over an 8-month period, from March 1 to October 30, 2023, among dentists throughout Tunisia. A structured questionnaire was distributed via email to evaluate knowledge of flexible RPDs, which was scored. Data were analyzed using SPSS version 20.0. Frequencies and percentages were calculated for qualitative variables, while means and standard deviations were determined for quantitative variables. Student's t-test was used for mean comparisons, and Pearson's chi-square or Fisher's exact test for categorical variables. A p-value of < 0.05 was considered statistically significant. A total of 98 dentists participated, with a majority being women (64.3%) and working in the private sector (87.8%). Most participants (76.53%) were unfamiliar with the trade names of flexible resins. Regarding clinical indications based on edentulism type and prosthetic treatment, 60% achieved a score of at least 75%. The overall knowledge score was 16 or lower for 65.3% of respondents. Additionally, 33.74% expressed the need for further training, while 36% frequently prescribed flexible RPDs, mainly for esthetic purposes. There was no significant correlation between knowledge level and clinical experience (p = 0.23), but the adoption rate of flexible RPDs significantly varied with experience (p = 0.045). Tunisian dentists' knowledge of flexible RPDs remains limited, necessitating improvement. Clinical practices should be updated in accordance with current recommendations, given the limited scientific evidence available.
