Automatic Teeth Recognition in Dental X-Ray Images Using Transfer Learning Based Faster R-CNN

Abstract

Computer aided diagnosis in dental treatment is highly desirable as it brings efficiency and accuracy in dental treatment. In this paper, an automatic teeth recognition method is proposed involving faster R-CNN method. The proposed method is implemented using a pre-trained ResNet-50 to automatically recognize tooth by its number. This paper follows the universal tooth numbering system to number the teeth. Obtained result is evaluated using mean average precision (mAP). The system achieved 0.942 mAP and thus can be considered as a reliable tool to aid dental care system professionals in automatic recognition of tooth.
