An EFDA performing coronal polishing should avoid polishing which of the following surfaces?

Exposed cementum and dentin are softer than enamel and can be easily abraded by prophy paste, causing sensitivity.
Which classification of furcation involvement indicates that the probe can enter the furcation but not pass through?

What is the purpose of an oral irrigation device (water flosser) in home care?
Answer: Flush debris and reduce bacterial load subgingivally
Oral irrigators flush food debris and reduce the bacterial load in periodontal pockets but do not remove plaque biofilm like mechanical methods.
