The aim of this work: Was to provide an insight into the design, development and operation of an application which allows the creation and maintenance of protected personal dental records on a global network. The first part is a guide through the software workflow, and the second part demonstrates the operating mode and implementation of the application. Materials and Methods: The application was developed in the Web2py network framework. Web2py provides an easy access and management of all files, as well as an overview of the base and the functions used in the application. The application consists of models, views, controllers and modules. Results: This application was designed for the patient and serves as their dental records which can be accessed via Internet, regardless the time and place, and with a password it provides access to the chosen dentist. Dental records contain all the information about previous dental treatments with the label of time and dentist who performed the treatment. Records consists of five sections: (a) Homepage (b) Medical history, (c) Oral status, (d) Procedures and (e) Notes and instructions. The sections are connected to each other, and every entry in one of the sections updates the data in the other divisions. All possibilities of work in the application are presented through the profile and records of the "demo patient". Conclusion: The developed application is patient-oriented and provides their longitudinal, lifelong dental records. In the context of dental informatics in Croatia and electronic management board it represents a different kind of approach than other systems known and used within this area.
