Abstract

Automation measuring of root canal length is an important factor in diagnosis and treatment procedures. In this paper, a semi automatic algorithm based on morphological features for measuring the length of root canal in radiography images is proposed. In this algorithm, using the preliminary low-level image processing techniques such as histogram equalization, denoising, enhancement in spatial and frequency domains, image enhancement carried out on the dental radiography image. Then, morphological operations are used to extract the pulp of teeth in a radiography image. A perfect set of scanned dental radiography images that have been labelled by specialists are used to evaluate the proposed algorithm. The obtained results show effectiveness of the proposed algorithm in real conditions.
