Image processing techniques used for dental x-ray image analysis

Classification of dental caries is important for the diagnosis and treatment planning of the dental disease, which has been affecting a very large population throughout the globe. It is also helpful for conducting detailed study and investigations about the nature of the dental disease. Classification of dental diseases is decided on the basis of certain criteria, such as based on whether the lesion is within the enamel, dentin or whether it touches the pulp. Dental caries are, clearly visible in the x-ray changes and it can be detected from the caries lesion present in the radiographs. In this paper we propose to show how image processing techniques will help check the x-ray and examine the extent to which the caries lesion is present and then classify the type of caries present in the dental radiograph.
