Assessment of Patients’ Knowledge and Awareness of 3D Technology in Dentistry in Chengalpattu District: A Cross-Sectional Study

Abstract

Background: Various three-dimensional (3D) technologies like computer-aided design and computer-aided manufacturing (CAD/CAM), intraoral scanning, cone beam computed tomography (CBCT), and 3D printing have revolutionized in modern dental practice. These technologies help in accuracy, precision, efficiency and patient comfort for diagnostic and treatment evaluation. Most of the research has focused on assessing knowledge of 3D technology among dental professionals and students henceforth very few studies explore in assessing awareness and knowledge among patients who benefits from these advancements. This study aims to assess the knowledge and awareness regarding the use of 3D technology in dentistry among patients in Chengalpattu District, Tamil Nadu, India. Materials and Methods: A descriptive cross-sectional questionnaire-based study was conducted among 202 patients attending dental clinics in Chengalpattu District. A structured questionnaire was fabricated to assess demographic details, awareness of 3D technology with applications.  Data were analyzed using descriptive statistics as frequencies and percentages. Results: A total of 202 participants were included in the study of which 32% belonged to the age group of 45–60 years, and 52.5% were male, 48.5% were various degree undergraduates, 98% had previously visited a dentist ,44.6% of the participants were aware of its use. Awareness through Dentists (39.6%), the internet and social media (38.6%), television or news media (24.8%), and friends or family members (20.8%), 59% of the participants were unsure about the benefits of using 3D technology, and 52.5% were uncertain about safety of using 3D technology in dental treatment,40.6% of participants felt more confident in dental treatments that involve 3D technology while 71.3% believed that the use of 3D technology increases the cost of dental treatment. About 38.6% of participants had exposure to 3D technology previously while 28.7% had experienced 3D scan for crown or bridge fabrication, 38.6% of participants rated their experience as excellent.,40.6% prefer choosing a dental clinic that uses 3D technology, 52.5% of participants would like their dentist to explain how 3D technology is used in their treatment and 41.6% strongly agreed that 3D technology should be widely adopted in dental practice. Conclusion: The findings of this study suggest that the patient awareness about 3D technology in dentistry is limited in Chengalpattu District. However, patients showed positive attitudes toward the use of digital technologies in dental treatment. Educating patient about 3D technologies can increase acceptance and help them to gain confidence towards treatment procedures. The study highlights the importance of using patient-centered approaches while introducing digital dentistry into routine practice.
