Preventive practices of dentists in Phnom Penh, Cambodia

Objectives: To describe the preventive dental practices of general dentists in Phnom Penh, Cambodia. Methods: Dentists from 100 randomly selected dental clinics in Phnom Penh were interviewed by one of 3 trained interviewers. Open and closed questions included: background information, knowledge of prevention, resources for prevention, and preventive practices. Data presented are from the results of the first 30 participants. Results: 66.7% of dentists believed prevention was very important. 87% gave oral health education at least several times a week. 42.9% never used F varnish and 48.3% never used resin sealants. When shown a picture of a white spot lesion, 30% said they would provide no treatment, 6.7% would apply fluoride, and 46.7% would restore. 53.3% believed that caries in enamel is reversible. 89.7% said preschoolers should use a F toothpaste, and 90% said this should be low F paste. 70% said women should take F tablets during pregnancy. 85.2% said that all patients should be recalled 6 monthly. 79.3% said that plaque was composed mainly of food particles. 31% were in favor of a sugar tax, and 83.3% in favor of water fluoridation. 68.9% agreed that selling of sugary foods and drinks at schools should not be permitted. 86.3% of dentists suggested having more education on prevention at dental conferences. Conclusions: Cambodian dentists have limited knowledge of dental prevention and the basic principles of cariology and provide only limited preventive interventions for their patients. This survey is the first important step in a campaign to improve preventive practices of Cambodian dentists; actions should be taken to orientate dentists towards implementing evidence-based prevention in their clinics
