True or FalseA nonabrasive dentifrice is indicated to prevent the possibility of abrasion when pontic or crown facings are made of acrylic, when the gold of the partial denture is highly polished and could be scratched, and when areas of root exposure are on abutment teeth. A fluoride-containing dentifrice is important for protection of remaining tooth surfaces, particularly exposed cementum; acidulated fluoride preparations are contraindicated for porcelain and composite restorations.

Both statements are true.

Explanation:

A nonabrasive dentifrice is indicated in order to to prevent scratching of gold prostheses and acrylic. It is indicated to prevent the possibility of abrasion when pontic or crown facings are made of acrylic, when the gold of the partial denture is highly polished and could be scratched, and when areas of root exposure are on abutment teeth.

For caries protection for remaining tooth structures, fluoride dentifrice is recommended as it is important for protection of remaining tooth surfaces, particularly exposed cementum.

Due to acidity Acidulated Fluoride Preparation is contraindicated in an oral cavity with porcelain and composite restorations.
