Awareness of Biological Hazards and Radiation Protection Techniques of Dental Imaging Among Dental students in South Chennai-A Questionnaire study

Abstract

Abstract: Aim and objectives: To assess the attitude and awareness about Biological Hazards of dental X-rays and appropriate radiographic protection techniques of dental imaging among dental students in South Chennai. Materials and methods: The study participants comprised of 100 undergraduate dental students (pre-clinical & clinical) in South Chennai, whose curriculum includes X-ray physics. The information was collected via an online 15 structured multiple choices questionnaires. Statistical analysis was performed using Pearson correlation co-efficient test to know the validity of questionnaire and any P≤0.05 was considered statistically significant. Results: Of all the 100 undergraduate dental students enrolled in this study, 80% of dental students were aware of harmful effects of dental X-rays. While majority of dental students (25%) were unaware about which speed film used to reduce radiation exposure. It was found less percentage of dental students (47%) were aware of the contraindication of radiography during first trimester of pregnancy. However, majority of dental students (68%) were aware of position-distance rule and remaining were unaware about this rule. Conclusion: This study highlights significant awareness among dental students in South Chennai regarding biological hazards and radiation protection techniques in dental imaging. The majority demonstrated a commendable understanding of crucial aspects, such as the harmful effects of dental x-rays, radiation protection recommendations, and the composition of the intensifying screen. However, variations in knowledge were observed, particularly concerning radiation dosage and contraindications during pregnancy. This underscores the importance of continuous education and training in radiation safety within the dental community.
