5 Definitions

Candidate refers to the person seeking credit for this unit standard.

Dental caries is a disease in which bacteria destroy hard tooth structure.

Periodontal disease is a bacterial infection of the gums and other tissues that attach to and anchor teeth to the jaws. It is caused by an accumulation of dental plaque on the teeth.

Primary dentition refers to deciduous teeth, often called 'baby teeth'.

Secondary dentition refers to permanent teeth, often called 'adult teeth'.
