What determines cariogencity - Answer The degree of cariogenicity includes physical
, form, texture and consitency; it's retention and
clearance time and frequency of use
Critical pH for enamel breakdown is - Answer 4.5 to 5.5
Critical pH for root surface breakdown is - Answer 6.0 - 6.7
Types of Mucosal Tissues - Answer Masticatory mucosa
Specialized mucosa
Lining mucosa
Masticatory mucosa - Answer Attached gingiva, hard palate.
The Periodontium - Answer Gingiva
Cementum
Periodontal ligaments
Periodontal ligament fibers
Alveolar bone
Lining Mucosa - Answer Covers the inner surfaces of the lips and cheeks, floor of the
mouth, underside of the tongue, soft palate, and alveolar mucosa.
Specialized Mucosa - Answer Covers the dorsum (upper surface) of the tongue, taste
buds and tonsils region, papillae, filiform,fungiform,circumvallate,foliate
Role of the pdl - Answer The periodontal ligament (PDL) is the fibrous connective tissue
that surrounds and attaches the alveolar bone to the cementum and allows for
masticatory forces
Lamina dura - Answer the bone that lines the tooth socket and appears radiopaque.
Supporting bone - Answer surrounds the alveolar bone proper and provides additional
functional support
