  Research has shown that the general health and oral health of an individual
are closely related. Accordingly, current practice of isolating the information
base of medical and oral health domains can be dangerous and detrimental to the
health of the individual. However, technical issues such as heterogeneous data
collection and storage formats, limited sharing of patient information and lack
of decision support over the shared information are the principal reasons for
the current state of affairs. To address these issues, the following research
investigates the development and application of a cross-domain ontology and
rules to build an evidence-based and reusable knowledge base consisting of the
inter-dependent conditions from the two domains. Through example implementation
of the knowledge base in Protege, we demonstrate the effectiveness of our
approach in reasoning over and providing decision support for cross-domain
patient information.
