Author(s): Nandita R and Abirami Arthanari*
Introduction: An orthopantomogram is a panoramic scanning dental X-ray of the upper and lower jaw. An OPG is a wide view x-beam of the lower face, which shows all the teeth of the upper and lower jaw on a solitary film. It exhibits the number, position, and development of the multitude of teeth including those that have not yet surfaced or emitted. The OPG consists of a rotating arm with the X-ray source at one end and the film mechanism at the opposite extremity. AIM: The aim of the present study is to analyse the knowledge of OPG and CBCT among dentists. Materials and methods: Self-administered questionnaire of close-ended questions was prepared, and it was distributed among dental students from February to March 2021 through the online survey “google forms”. Data was analysed with the SPSS version (22.0). Descriptive statistics as percent were calculated to summarise qualitative data. Results: The questionnaire was distributed among 200 participants. 89.5% of the participants agreed that CBCT was a better diagnostic adjunct than OPG in the field of orthodontics. 71.5% of the participants disagreed that OPG is the preferred mode of 3D imaging for the head and neck region. 82.5% of the participants disagreed that OPG is better to see the root resorption. 81% of the participants agreed CBCT can be used for superimposition to evaluate the pre-post treatment changes. Conclusion: Dental practitioners had overall good knowledge and awareness on the more reliable source for human identification. In comparison with the experience of a dentist, 5-10 years of experience had good knowledge and awareness regarding the more reliable source for human identification.
