摘要Objective:To analyze the current status of knowledge and practices among the Moroccan dentists in the region of Rabat-Salé-Kenitra,towards radiation protection.Methods:This is a cross-sectional study based on a questionnaire related to knowledge and practice regarding radiation protection of patients and dental staff from April to June 2022.The study sample included 325 dentists practicing in the Rabat-Salé-Kénitra region.The target population consisted of all dentists working in public,semi-public and private workplaces.Results:96.6％of dentists were aware of radiation protection.However,nearly 35％were aware of ALARA(as low as reasonably achievable)principle and 73.9％thought that dental X-rays are harmful.63.6％of subjects used digital image receptor.Only 16.7％of them used a film holder and more than 60％didn't follow the position and distance rule.The median knowledge score was 7[5,9],and there was a statistically significant difference ac-cording to dentist qualification(P=0.007),dental radiation protection continuous training(P＜0.0001),age(P=0.007)and years of experience(P=0.039).The median practice score was 5[4,6]and there was a statically significance association according to workplace setting(P=0.001).There was a significant positive relationship between knowledge score and practice score(r=0.24,P＜0.0001).Dentist qualification(OR 0.51,95％CI:0.27-0.94,P=0.03)and continuous training(OR 2.40,95％CI:1.47-3.93,P＜0.0001)were significant predictors of knowledge,while workplace setting(OR 0.54,95％CI:0.32-0.93,P=0.027)and knowledge score(OR 1.24,95％CI:1.12-1.38,P＜0.0001)were predictors of practices.Conclusion:Improving dentists'knowledge of radiation protection measures and tools as well as dose reduction techniques could increase their safe practices in dental radiology.
