Abstract :
Dental Imaging X rays, also called as Intra Oral Periapical Xrays (IOPA) are used for the diagnosis in clinical application in real time and can be segmented using various image processing techniques. These segmentation techniques are used to define the segmentation of Dental x rays , which are used to identify caries lesions, fracture of the dental structures including the tooth and supporting alveolar structure, disease identification like periodontitis and for other treatment modalities like Root Canal treatment and hence help in treatment planning strategies. Segmentation using manual method for IOPA is very complicated, laborious and time consuming and retrieving and segmenting these x rays from a huge database is very cumbersome. Here, we propose a three-step procedure for the segmentation of every individual tooth, where, first off, preprocessing is finished by employing a median filtering and then we utilize K means clustering with morphological operations which are utilized to separate the tooth structures from the Dental X-ray pictures. Performance analysis is concluded from the analysis of 10 periodical X-ray pictures and we were able to see that the accuracy of the strategy is around ninety seven percent.
