Knowledge Gaps and Clinical Practice Patterns in Provisional Fixed Dental Prostheses Among Dentists in Saudi Arabia—A Cross-Sectional, Survey-Based Study

Background/Purpose: Teeth prepared for fixed dental prostheses are subject to various types of insults in the oral cavity. Therefore, to protect the tooth, the pulp, and supporting structures, provisional restorations are mandatory. Our study aimed to evaluate the knowledge and clinical practices regarding provisional fixed dental prostheses (PFDPs) among dental professionals in Saudi Arabia. Materials and Methods: A cross-sectional study based on a self-administered online survey was conducted among 312 dentists (general practitioners and specialists) across Saudi Arabia. The questionnaire assessed participants’ knowledge (11 items) and clinical practices (9 items) related to PFDPs. Statistical analyses included descriptive statistics, chi-square tests, and multivariate logistic regression. Results: Only 46.5% of respondents demonstrated adequate knowledge of PFDPs. Knowledge was significantly higher among specialists than general practitioners (57.4% vs. 41.7%, p = 0.011), and specialists were more likely to recognize the influence of PFDPs on treatment outcomes. Clinical practice patterns indicated that even though 94.2% of respondents frequently placed PFDPs, only 66.0% always did so. Moreover, 21.2% of respondents rarely or never disinfect PFDPs. Public sector dentists and specialists were more likely to use custom-made PFDPs. Key gaps in knowledge were observed regarding the materials and equipment used in the fabrication of PFDPs, particularly concerning CAD/CAM technology. Conclusions: Although most dentists in Saudi Arabia provided PFDPs to their patients, significant gaps remain in their knowledge, particularly regarding fabrication materials and techniques. Targeted educational interventions, especially for general practitioners, are needed to enhance clinical outcomes.
