SOUTHERN ASSOCIATION OF INSTITUTIONAL DENTISTS — Self-Study Course Module 9 CLINICAL CONCERNS IN DENTAL CARE FOR
PERSONS WITH MENTAL ILLNESS
Purpose of this Module
The information presented in this module is intended to provide the institutional dental staff with a compre- hensive discussion of oral health care for persons with mental illness in institutional settings as well as thechallenges faced by the dental profession treating these persons in outpatient settings.
After reviewing this module, the participant will be able to: 1. Describe five psychiatric disorders commonly encountered in mental health facilities.
2. Discuss the oral manifestations commonly occurring in these five disorders.
3. Identify the drugs commonly used to treat these disorders.
4. Describe potential side effects and significant interactions encountered with psychotropic medicines and drugs used in dentistry.
5. Discuss barriers to dental care and general concerns in the provision of dental care in mental health SOUTHERN ASSOCIATION OF INSTITUTIONAL DENTISTS — Self-Study Course Module 9 CLINICAL CONCERNS IN DENTAL CARE FOR
