a) Not visible.
b) At the cementoenamel junction.
c) 1-2 mm.apical to the cementoenamel junction.
d) 3-4 mm.apical to the cementoenamel junction.

2) Frequent brushing helps to prevent calculus formation by:

b) Breaking up of the matrix of the plaque.
c) Removing Ca/P ions that attach to the tooth surfaces.

a) PMA index.
b) plaque index.
c) gingival index.

a) gingival margin and the cementoenamel junction.
b) gingival margin and the bottom of the periodontal pocket.
c) cementoenamel junction and the bottom of the periodontal pocket.
d) gingival margin and the most coronal portion of the connective tissue attachment.

9) Inadequate margins of restorations should be corrected primarily because they:
a) retain food debris.
b) cause occlusal disharmony.
c) cause mechanical irritation.
d) interfere with plaque removal.

10) Which of the following teeth have the poorest prognosis following furcation therapy:
