Evaluation of requirement of taking panoramic radiographs in children less than 6 years of age - A retrospective study.

Abstract

To evaluate the prevalence of prescribing panoramic radiographs in children less than 6 years of age. The retrospective study was conducted in a dental institution in Chennai between December 2019 and January 2021. Details of all the children less than 6 years subjected to panoramic radiographs were collected. The reason for taking panoramic radiographs was also recorded. Chi-square tests were done to statistically analyze the data, and the significance level was set at 0.05. Out of 2,847 children less than 6 years of age visiting the dental institution, 1.08% (31 children) were advised to take an orthopantomagram (OPG) during the study period. Early childhood caries (75% in males and 66.7% in females) was found to be the most common reason for taking panoramic radiographs followed by developmental disturbances (12.5% in males and 13.3% in females). Chi-square test showed statistical significance between males and females (<i>P</i>- value = 0.003 and 0.002) for the reasons for taking panoramic radiographs in children. Usage of radiographic techniques, especially panoramic radiographs should be limited for children under 6 years of age unless absolutely necessary.
