Q

Classify gingival recession?

A

Gingival recession can be classified according to Millers into –
Class I : marginal tissue recession that does not extend to mucogingival junction. No soft tissue or interdental bone loss.
Class II : marginal tissue recession extend to or beyond mucogingival junction. No soft tissue or interdental bone loss.
Class III: marginal tissue recession extend beyond mucogingival junction. soft tissue or interdental bone loss & malposition of teeth
Class IV: marginal tissue recession extend beyond mucogingival junction. SEVERE soft tissue or interdental bone loss & malposition of teeth

Q

Classify furcation?

A

According to Glickman–
Grade I – incipient bone loss, supra bony pocket involving new radiographic changes
Grade II – partial bone loss (cul-de-sac appearance) radiographic changes may or may not be there
Grade III- interarticular bone is completely lost, through passes through and through, radiographic changes seen, furcation not visible clearly clinically
Grade IV -gingival tissue recedes apically furcation opening is seen clinically.
