DEXSY2 is a dental expert system, which diagnoses oral diseases and offers a treatment course. The system which is designed and implemented from scratch is capable of diagnosing among thirty five oral diseases and offering a course of treatment for each. It uses a decision tree for its representation of knowledge, and each of its nodes contains a frame. The knowledge base of the system contains a tree for diagnosing the diseases, a tree for its drug treatment, and a set of signs used in the diagnosis and treatment. Reasoning in the system is based on a forward chaining and depth-first search of the tree. It takes into consideration the uncertainties involved and avoids asking repetitive questions. DEXSY2 also diagnoses a combination of diseases. It also provides various explanations for its decisions.
