Statement of the problem:

The long-term clinical success of indirect intracoronal restorations is reliant on the proper selection and application of resin cements, which are critical for achieving a durable bond and marginal seal. However, a significant disparity exists between established evidence-based protocols and real clinical implementation, driven by variability of available cement systems ranging from technically demanding etch-and-rinse to simplified self-adhesive types coupled with high technique sensitivity inherent to adhesive procedures. Within the Egyptian dental community, data on how practitioners navigate this aspect is absent. The specific levels of knowledge, prevailing attitudes regarding efficacy and difficulty, and actual clinical practices of Egyptian general dentists and specialists concerning resin cement use for indirect restorations remain unknown. This critical knowledge gap hinders the development of targeted educational and training programs, ultimately impeding efforts to optimize restoration longevity. This study therefore aims to systematically investigate the Knowledge, Attitude, and Practice (KAP) of Egyptian dentists to identify misconceptions and practice deficiencies, thereby providing an essential evidence base for improving clinical outcomes.

Aims of the Study:

This cross-sectional study aims to comprehensively assess and compare the current state of knowledge, attitudes, and clinical practices regarding the use of resin cements for indirect intracoronal restorations among a representative sample of Egyptian general dentists and dental specialists.

Inclusion Criteria:

• General dentist Specialist in conservative dentistry Specialist in another field of dentistry

Exclusion Criteria:

• apply to undergraduate students. By involving a diverse sample of professionals, the study aims to capture a comprehensive picture of knowledge, attitudes, and practices regarding resin cement selection and application in the Egyptian dental context.

The study will be conducted across academic dental institutions, teaching hospitals, and private dental clinics in Egypt, with a particular focus on practitioners working in restorative dentistry. This includes both general dentists and specialists who are directly involved in the placement of indirect intracoronal restorations and the selection of resin cements.
