What is generally the best restorative material choice for a Class V (cervical/gingival third) lesion?
Show answer and explanation
Correct answer: B. A resin-modified glass ionomer or composite resin — materials that tolerate the flexure and moisture common at the cervical area and can bond to both enamel and dentin/cementum
Class V lesions are often near the CEJ where flexural (abfraction-type) stresses and moisture control are challenging. Resin-modified glass ionomer (which bonds well even in less-than-ideal moisture conditions and releases fluoride) and bonded composite are the materials of choice; amalgam is not adhesive and is rarely indicated here today.
