AbstractAim: To compare the opinion regarding usage of bisecting-angle technique and the paralleling techniques among dental professionals.
Material and methods: The present comparative, observational study was conducted in the Department of Pedodontics, Buddha Institute of Dental Sciences & Hospital, Patna, Bihar, India. The research instrument was close ended questionnaire with 20 simple and straight-forward questions. These questions were broadly categorized under four factors like image accuracy factors, technical factors, operator and exposure factors and other factors. Questions included in the study sample was divided into five groups based upon their academic levels and time frames of usage of techniques such as Group, I (Third-year year undergraduate students), Group II (Fourth-year year under-graduate students), Group III (Students, who are pursuing internship), Group IV (Post graduates students), and Group V (General dental practitioners). Total 250 undergraduate, interns, postgraduate students and private practitioners were involved in the present study, with 50 individuals in each group. Every participant was explained through the study and those who were willing to participate were included in a present study. Each question had three options 1- Bisecting angle technique 2- Paralleling technique and 3-Other techniques preferred for that particular question.
Results: Out of 250 participated in this study, 50 were third year students; 50 were fourth year students; 50 were students perusing their internship; 50 were post-graduate students, and 50 were general dental practitioners from the city. Most of the participants opted for bisecting angle technique with p value≤ 0.05 and found as significant. In aspect of exposure parameters, results are in favour of paralleling technique and p value is ≤ 0.05. In aspect of the operator and patient comfort there is an equal opinion most of them opted for bisecting angle technique and paralleling technique p-value is significant. In aspect of image accuracy p-value is significant for paralleling technique.
Conclusion: There is sufficient knowledge about the techniques, but lack of application decreases their ability to get more accurate diagnostic radiograph. Paralleling technique being the most accurate in image accuracy should be emphasized to practice and needed to be modified in conditions where it is not feasible to deal with.
