Evaluation of knowledge, attitude, and practice regarding positron emission tomography scan: A cross-sectional survey

Abstract

Background and Objectives: Positron emission tomography (PET) scan is a radionuclide imaging technique with implications in diagnostic and therapeutic oncology. Due to the complexity in the technique and cost factor, this technique has not been popular among the general and specialty dental practitioners. This survey study utilizes the Likert item to evaluate the intensity of response toward the technical and practical aspects of PET scan in dentistry. Materials and Methods: A representative population of 500 respondents was chosen by randomization. These respondents were either postgraduates or staff of various dental specialties. A close-ended questionnaire was provided inclusive of the Likert items. Simple arithmetic percentages were calculated to evaluate the knowledge and practice. One-way ANOVA test was done to evaluate the Likert items and regression analysis was done to find a correlation between the questions asked in attitude. Result: Statistically significant values (P = 0.0010) were obtained while evaluating the Likert items. Linear regression analysis showed a strong correlation between the questions asked in attitude. Conclusion:The overall impression of the survey revealed that the knowledge of the respondents was above optimum. However, the responses in attitude revealed a lack of practical knowledge and inhibitions pertaining to prescribe PET scan in dentistry.
