Development of the decision-making systems has been highly demanded to provide objective evidence for the decisions of experts, especially in medicine, and a variety of systems have been developed by means of the state-of-the-art technology. In orthodontics, there has been no objective criterion for the decisions of whether or not to perform one of the invasive treatments, tooth extraction. Therefore,...
In this paper, decision-making models for orthodontic tooth extraction in treatment planning that are fully compatible with the digital associative processor has been developed. The architecture of the models was designed according to the specification of the digital associative processor. Feature variables were extracted from the pre-treatment clinical records of orthodontic patients and projected...
Intraoral radiographs have been taken to diagnose periapical lesions. Subsequent endodontic treatment needs to be evaluated quantitatively, that is often difficult due to various imaging factors as well as subjective visual interpretation. Therefore, we sought to establish an image analysis based quantitative model to evaluate endodontic treatments (40 effective and 43 noneffective cases). To normalize...
The purpose of this paper is to characterize the morphological information of craniofacial structure. Firstly, the morphological feature parameters of cephalometric tracings are extracted using image processing techniques. Then, based on these parameters, the morphology of craniofacial structure is classified using K-means method. Afterwards, four morphology related landmarks such as Go, Po, N, and...
The purpose of this study was to evaluate the pre orthodontic trainer appliance efficiency in patients with orthodontic abnormalities. The evaluation was done during sucking on an empty straw. Ten patients (male and female), between 8 and 12 years of age, were examined. Electromyogram recordings were made at the initial stage of myofunctional therapy. The electrodes were placed on the right anterior...
