Query: A new method for determining the filled point of the tooth by Bit-Plane
  Algorithm   Up to now, researchers have applied segmentation techniques in their studies
on teeth images, with construction on tooth root length and depth. In this
paper, a new approach to the exact identification of the filled points of the
tooth is proposed. In this method, the filled teeth are detection by applying
the Bit-Plane algorithm on the OPG images. The novelty of the proposed method
is that we can use it in medicine for the detection of dental filling and we
calculate and present the area of the filled points which may help dentists to
assess the filled point of the tooth. The experimental results, confirmed by
the dentists, clearly indicate that this method is able to separate the filled
points from the rest of healthy teeth completely.
