Objective. e purpose of the study is to evaluate a user-friendly, comprehensive, fully integrated web- and mobile-based application that was specifically developed to guide learners and help them practice and train in pulpal and periapical diagnosis. Methods. e software was designed for assistance in the diagnosis of the pulpal and the periapical area. e software contained questions and tests, e.g., presence or absence of signs and symptoms, cold test, percussion, palpation, and radiographic ex- amination that the user must answer to arrive at the final diagnosis. An electronic survey was prepared to evaluate the ef- fectiveness, productivity, and accurateness of the software. e software and the electronic evaluation survey were sent by e-mail to dental students, endodontist, general dentists, and dental interns who study or work in four Saudi dental colleges. Data was analyzed using descriptive statistics. Result. A total of 203 questionnaires were completed. Results showed that 29% of the participants were highly satisfied with the software; 40% gave a very good rating about the application satisfaction, while only 2% reported a poor degree of satisfaction with the software. Results also showed that students accurately selected the correct diagnosis but received relatively low diagnostic proficiency scores because they did not request diagnostic data in a pattern similar to experts. Conclusion. In conclusion, the software is promising as an effective and efficient tool for teaching and assessing the diagnostic skills of learners. 1.Introduction e importance of advanced diagnostic skills in the practice of endodontics has been underscored in the 2008 AAE- sponsored symposium on endodontic diagnosis [1]. e diagnostic process is not a pure science, and the necessary examining equipment may not be the diagnostic tool or instrument, but the diagnostician who will perform the test and arrive at a reliable conclusion. Practitioners should be equipped with the basic requirements and skills necessary to perform this procedure, including knowledge, training, interest, curiosity, patience, the art of listening, and above all common sense. Endodontic diagnosis is similar to a puzzle, in that di- agnosis cannot be made from a single, isolated piece of information [2]. e clinician must systematically gather all of the necessary information to make a “probable” diagnosis. When taking the medical and dental history, the clinician should already be formulating in his or her mind a pre- liminary, but logical, diagnosis especially if there is a chief complaint. e clinical and radiographic examinations, in combination with a thorough periodontal evaluation and clinical testing (e.g., pulp and periapical tests), are then used to confirm the preliminary diagnosis. Diagnostic skills need practice, training, and experience to develop.
