abstract = "In dentistry, radiological examinations help specialists by
showing structure of the tooth bones with the goal of screening
embedded teeth, bone abnormalities, cysts, tumors, infections,
fractures, problems in the temporomandibular regions, just to cite
a few. Sometimes, relying solely in the specialist's opinion can
bring differences in the diagnoses, which can ultimately hinder
the treatment. Although tools for complete automatic diagnosis are
no yet expected, image pattern recognition has evolved towards
decision support, mainly starting with the detection of teeth and
their components in X-ray images. Tooth detection has been object
of research during at least the last two decades, mainly relying
in threshold and region-based methods. Following a different
direction, this paper proposes to explore a deep learning method
for instance segmentation of the teeth. To the best of our
knowledge, it is the first system that detects and segment each
tooth in panoramic X-ray images. It is noteworthy that this image
type is the most challenging one to isolate teeth, since it shows
other parts of patient's body (e.g., chin, spine and jaws). We
propose a segmentation system based on mask region-based
convolutional neural network to accomplish an instance
segmentation. Performance was thoroughly assessed from a 1500
challenging image data set, with high variation and containing 10
categories of different types of buccal image. By training the
proposed system with only 193 images of mouth containing 32 teeth
in average, using transfer learning strategies, we achieved 98% of
accuracy, 88% of F1-score, 94% of precision, 84% of recall and 99%
of specificity over 1224 unseen images, results very superior than
other 10 unsupervised methods.",
