Knowledge, Attitudes, and Practices Regarding the Association Between Periodontal Disease and Breast Cancer Among Libyan Dental Practitioners: A Cross-Sectional Study

Abstract

Emerging evidence suggests a significant association between periodontal disease and breast cancer. Dental professionals play a crucial role in recognizing oral manifestations of cancer therapy and providing comprehensive patient care. This study was conducted to evaluate the knowledge, attitudes, and practices regarding this association among dental practitioners and dental students in Libya. A cross-sectional study was conducted among 100 dental healthcare workers and students in Libya using a validated questionnaire assessing knowledge, attitudes, and practices regarding the association between periodontal disease and breast cancer across six domains. Data were analyzed using descriptive statistics, chi-square tests, and logistic regression. The mean total knowledge score was 61.4%, indicating moderate knowledge. Although 71.0% were aware of the periodontal disease-breast cancer association, significant gaps were identified: only 29.0% correctly identified mammography as the gold standard screening method, and merely 42.0% understood Tamoxifen's mechanism. Recognition of clinical signs was higher, with 79.0% identifying "peau d'orange" and 76.0% recognizing medication-related osteonecrosis of the jaw. A significant knowledge gradient was observed, with specialists scoring 56% higher than students (p<0.001). Logistic regression confirmed professional experience as the primary predictor of high knowledge scores; those with more than five years of experience were 3.4 times more likely to achieve high scores (OR=3.42, p=0.001). Gender, age, and practice setting were not significant predictors. Libyan dental practitioners have moderate knowledge of the link between periodontitis and breast cancer. While awareness is high, significant gaps exist in screening protocols and medication knowledge. Clinical experience strongly predicts better understanding, with specialists outperforming students. Improving oral-systemic health education and fostering collaboration between dental and medical professionals are essential for better patient care.
