Abstract

Title: Evaluating the Knowledge of Intraoral Scanners Maintenance and Troubleshooting Among Dental Practitioners in Tamil Nadu. Background: Intraoral scanners (IOS) have become integral to modern dental practices, providing a digital alternative to traditional impression-taking. However, effective use of these devices requires proper maintenance and troubleshooting knowledge. Despite their growing adoption, many dental practitioners face challenges in maintaining and troubleshooting intraoral scanners. Limited research exists on the awareness and practices regarding scanner maintenance and troubleshooting in Tamil Nadu. Objective: This study aimed to evaluate the knowledge of intraoral scanner maintenance and troubleshooting among dental practitioners in Chengalpattu district, Tamil Nadu, and identify gaps that could inform targeted educational interventions. Methods: A cross-sectional questionnaire-based study was conducted involving 102 dental practitioners from faculties, postgraduates, and practitioners in dental clinics across Chengalpattu. The structured questionnaire included questions about demographic information, scanner usage patterns, maintenance practices (Cleaning, Calibration, Software updates), and troubleshooting techniques. Data were analyzed using SPSS software to assess knowledge levels and practices. Results: The sample comprised 65.5% women and 34.1% men, with 49.5% of participants using intraoral scanners for less than six months. Among the scanners used, 46% were Sirona Cerac, 29% 3M True Definition, and 20% Align Technology iTero. While most participants cleaned their scanners after each use (55%), only 27% cleaned them daily. Calibration was performed daily by 43.9%, and 68% regularly updated their software. Common technical issues included failure to turn on (27.6%), connectivity issues (20.4%), and poor image quality (19.4%). For troubleshooting, 46.5% referred to user manuals, and 34.3% contacted manufacturer support. Discussion: The study revealed significant gaps in knowledge regarding proper maintenance, including daily cleaning, calibration, and software updates. Many practitioners were unfamiliar with advanced cleaning methods and troubleshooting techniques, leading to reliance on external support. This highlights the need for comprehensive training that incorporates both clinical and technical aspects of intraoral scanner use. Conclusion: Dental practitioners in Chengalpattu district, Tamil Nadu, exhibit knowledge gaps in the maintenance and troubleshooting of intraoral scanners. Targeted educational programs focusing on these aspects are essential to enhance scanner performance, minimize technical disruptions, and improve patient care. Integrating these topics into dental curricula and continuing education programs could ensure more effective use of digital technologies in dental practices.
