Periodontal implications of Class II restorations. Clinical and SEM evaluation.

ABSTRACT

30 subjects with class II silver amalgam restorations were studied to evaluate the influence of these restorations on periodontal health of the adjacent region. The incidence of overhangings were noted. The periodontal changes were recorded with the help of indices. The surface of the restoration and the interface between the restoration and the cavity margin were observed on extracted teeth under SEM. The gingival and periodontal status at the site of the restoration were affected by the restoration and the restoration showed a rough surface as compared to the enamel on SEM examination.
