Use Of Clinical Competency Examinations For Dental Hygiene Licensure, Jocelyn D. Weinhagen, Tara L. Newcomb, Brenda T. Bradshaw

Dental Hygiene Faculty Publications

Dental hygiene licensure with a clinical competency examination (CCE) using a live patient has been required by state licensing boards since 1929. Clinical competency examinations were initially used when dental training was poorly developed, non-standardized, and largely based on the apprenticeship model. Currently, Canada and the state of California have removed the requirement of passing a CCE for dental hygiene licensure, provided certain requirements have been met. Dentistry is the last health care profession to mandate that graduates pass a CCE. The vast majority of dental licensing boards continue to require that third party testing agencies validate the clinical skills …

The Usual Suspects: A Review Of Common Dysbiosis Of The Human Mouth, And The Associated Microbial Species, Sophie Katherine Shields

Honors Theses and Capstones

The mouth, often referred to as the oral cavity in scientific literature, is described as the second most diversely populated microbiome in the human body, only after the gut. The cavity’s temperature, abundant water, high nutrient levels, and diversity of sites are all critical factors that make the oral cavity a space booming with life. The mouth harbors over 700 species of bacteria, in addition to numerous fungi, viruses, and protozoa species. Together, when working in harmony, these species provide critical supports to the functions of the human body. When dysbiosis occurs, however, the overgrowth of a single species may …
