Background and Aim: Proper designing of partial denture frameworks is the duty of dentists, but this task is often abdicated to technicians because of lack of time and experience. Computer assisted learning and designing can be used for both training dental students and helping dentists design proper frameworks. As the first step to prepare software for framework designing, this study evaluated the agreement on different framework designing principles, among prosthodontists of dental schools in Iran.
Materials and Methods: A questionnaire consisting of 121 design rules was sent to 41 prosthodontists at seven dental schools in Iran .The percentage rate of agreement on results was used for data analysis.
Results: The percentage of rules accepted by more than 60% of the prosthodontists was 76.2%. It consisted 80% saddle rules, 76.2% rest rules, 78.4% clasp rules, 63.6% maxillary major connector's rules and 80.9% mandibular major connector rules.
Conclusion: The percentage of accepted rules by Iranian prosthodontists was 76.2%. Maxillary major connectors had the least acceptance.

Background and Aim: Designing removable partial dentures is one of the most important phases of prosthetic treatments. Computer can be used to facilitate and increase accuracy of removable partial denture design. The aim of this study was to develop a software for removable partial denture design.

Materials and Methods: A questionnaire (discussed in part I) and major textbooks, were used to determine the design rules.  The software (RPD Graph) was developed using Visual C++ and Maryam program. The RPD Graph can determine the classification of partial edentulous arch. With defining the missing teeth and providing data about prognosis and conditions of abutment teeth, the removable partial design will be developed by RPD Graph. This software is a knowledge-based system which has specific characteristics. It can be used as an educational tool for teaching RPD design and as a clinical tool for supporting clinician's decision. In addition it can be developed to more complete softwares.

  Background and Aims: Classification is a fundamental issue in quantitative studies of any phenomenon and has been known as a necessity for the advancement of science. Using a standard record system for diseases is critical for research purposes and also could improve the quality of medical health services. In this study, after evaluating current codding systems in oral medicine, we designed a software for systematic coding and registration of Oral and Maxillofacial diseases based on the latest update of the World Health Organization ICD-10 classification system in 2010.

  Materials and Methods: Based on the latest WHO ICD-10 update in 2010 and by using software s as: vb.net, net framework, SQL Server and Microsoft Visual Studio, standard coding software for recording patient's data at the department of Oral Medicine, School of Dentistry, Tehran University of Medical Sciences was designed. Data from all patients were codded by standard ICD-10 codes and registered by the software. Also an online portal for recording patient's data which could be used nationwide was designed. By d esigning this software the process of forming and registering patient's records, and their treatment process is facilitated . An archive of patient data was also stablished .

  Conclusion: As a result , this software in addition to maintaining patient data , facilitate studies and research projects greatly. It’s recommended that the Iranian Ministry of Health and Medical Education as the concessioner of this software, improves codding and registration systems of oral diseases at the dental schools by developing this software.

  Aesthetic and smile design is one of the most important motivations for going to dentists and one of the most of researchers’ attention. The most important aspect of the remedy is to diagnose, especially when aesthetic is concerned and dentist should interfere the patient actively in the treatment planning. It means dentist must know what is aesthetic in patient points of view. One way to achieve this goal is digital imaging, patients images taken by digital intra oral cameras transfer to the computer and some changes done on their primary images and define all possible looks and at the end, all these looks must be shown to the patient by dentist and decide for the true remedy plan. This article introduced the software, which has prepared this aim that is easy to use and has no expense.
