Knowledge, attitude, and practice in diagnostic dental radiology: an Egyptian survey with a global perspective

Many surveys report less than optimum knowledge, attitude, and practice (KAP) of dental imaging for patient and operator safety. This study aimed to assess the KAP for diagnostic imaging among dentists in light of global practices and recent recommendations.

A cross-sectional survey was conducted using a structured questionnaire that was electronically distributed through dental social media platforms between March 1st and June 30th, 2022. Forty-seven questions evaluating demographics, knowledge, practice, and attitude were included. The survey targeted Egyptian dentists practicing in Egypt.

Two hundred and twenty-eight dentists of different specialties responded. Fifty-nine percent of the dentists were not familiar with the ALARA principle. Fifty-three percent never use lead aprons. Dentists (16.6%) who practiced in facilities with cone-beam computerized tomography (CBCTs) showed significantly (p = 0.000) higher knowledge scores (7.89 ± 2.63) than those who didn't have CBCTs (6.16 ± 2.67). There was no statistical difference in training received (p = 0.345) between the different specialties. Most dentists (79.4%) were interested in increasing their knowledge of radiation safety.

Within the limitations of this study, there is a need to educate dentists on radiation hazards, child-sized imaging protocols, and how to implement the ALARA principle. Training materials freely available on reliable websites should be disseminated. Regulations should include auditing referrals and periodic calibration of X-ray units.
