Cross-sectional study assesses knowledge, attitude, and practice of overdenture in older adults, suggesting need for education.
Introduction: Complete overdenture is an important treatment option for edentulous patients, but limited data exist on public awareness. This study aimed to assess the knowledge, attitude, and practice (KAP) regarding complete overdenture among middle-aged and elderly individuals aged 45 years and above. Methods: A cross-sectional study was conducted from November 2023 to July 2024 at Changzhi People’s Hospital in Changzhi City. Results: A total of 602 participants provided valid questionnaires, including 318 females (52.82%). The participants showed poor knowledge (median score: 6 [2, 11], possible range: 0– 20), positive attitude (median score: 27 [24, 30], possible range: 8– 38), and positive practice (median score: 25 [20, 27], possible range: 6– 30). The Structural equation modeling (SEM) analysis indicated that knowledge directly affected attitude (β = 0.572, P < 0.001), and attitude strongly influenced practice (β = 0.807, P < 0.001). Attitude fully mediated the association between knowledge and practice (indirect effect: β = 0.462, 95% CI: 0.392– 0.531, P < 0.001). Conclusion: Middle-aged and elderly individuals showed poor knowledge but positive attitudes and practices regarding complete overdenture, indicating the need for targeted education.
