Aims of epidemiology in periodontal disease
A
- Prevelance and severtity of periodontal diseases
- Aetiology
- Preventative and therapeutic measures

Q
Radiographic assessment of periodontal health includes
A
- Presence of intact lamina dura
- Width of periodontal ligament space
- Morphology of bone crest
