CASE B
A 25-year old female presents for dental hygiene care. Her records indicated that 10 months have lapsed since receiving dental hygiene care and she scheduled the appointment because her teeth are sensitive when she eats candy and her "gums" hurt when she brushes her teeth. She reports an arrhythmia but is not sure of the type or cause and irregularly takes the prescribed medication for its treatment. Her vital signs are within normal limits.
During the dental and periodontal assessment, you record generalized marginal gingival inflammation, generalized moderate interproximal subgingival calculus deposits, generalized bleeding on probing, with 2-4 mm probing depths. Existing restorations include teeth #14-MO, #4-MOD, #13-MO, #18-MO, and #19-B. Radiographs reveal no evidence of bone loss, proximal carious lesions on 29D, 30M, and 19M and restoration overhangs on #14M and #4D. She brushes once a day and does not use an interproximal cleaning aid.
-All of the following are related to the overhanging restorations EXCEPT one. Which one is the EXCEPTION?

A) Increase bacterial plaque biofilm retention
B) Restorations should be replaced
C) Restorations are risk factors for periodontal disease
D) Restorations are treated using margination procedures
