The implementation of expert system was widely used in then health field because the expert system was seen as a way of strong expert knowledge in certain field in a computer program. So that decisions could be given in intelligent reasoning. This work used certainty factor (CF) method implemented in a web-based expert system to diagnose various dental and mouth diseases.
