Knowledge, Attitude, And Possible Barriers to Fluoride Application Among Libyan Dentists in Benghazi

Abstract

Fluoride remains the most effective preventive measure against dental caries and for arresting early, non-cavitated lesions. Dentists have a pivotal responsibility to educate patients and the wider community and to provide reliable, evidence-based guidance on caries prevention and management. This study aimed to assess knowledge, attitudes, and perceived barriers to professional topical fluoride application among Libyan dentists in Benghazi. A descriptive cross-sectional study using a structured, closed-ended questionnaire was conducted among dentists working in public and private dental clinics. Data were collected via interviewer-administered questionnaires in clinic waiting areas and analyzed using SPSS. A total of 89 dentists participated; 70% were female, and more than half were aged 31–45 years. Over half (55%) supported fluoride use for children younger than six years. However, 60.6% expressed doubt that topical fluoride effectively prevents tooth decay, and only 56.17% believed it increases enamel resistance to caries. Conversely, 60.6% agreed that topical fluoride is safe when used at recommended concentrations and dosages. Despite these perceptions, most respondents (79%) reported that they do not routinely apply topical fluoride in daily practice. Reported barriers included limited knowledge and unfavorable attitudes, outdated undergraduate training, insufficient continuing education, and low participation in effective educational programs. These constraints may hinder the consistent implementation of evidence-based preventive dentistry in Benghazi clinics. Targeted continuing professional development, updated undergraduate curricula, and clear clinical protocols are needed to improve uptake substantially. Enhancing access to fluoride materials and strengthening patient communication may support routine implementation and ultimately improve population oral health outcomes in Benghazi.
