Alveolar Bone Loss, Plaque Index, and Gingival Index among Non-Diabetics Treated with Class II Amalgam Restorations for Different Service Lives |Biomedgrid

Objective: The present study aimed to evaluate the influence of different service lives of class II amalgam restorations on periodontal health among patients without diabetes. Materials and Methods: Two hundred and twenty-five patients without diabetes were divided into five groups (G1–G5) based on the ages of their class II amalgam restorations, that is, 2, 4, 7, 10, and > 10 years, respectively. Each group had 45 patients, aged 45–60 years. They were assessed for the plaque index (PI), gingival index (GI), rate of overhangs (OH), and alveolar bone loss (ABL), (OH and ABL, using panoramic radiographs). The data were analysed using the Scheffé test and analysis of variance. Results: The periodontal parameters of the examined groups demonstrated low and intermediate scores that ranged from 25% to 41% for ABL, 1.1 to 1.5 for PI, and 1.2 to 1.5 for GI. G4 and G5 had the highest scores for the three parameters (PI, GI, and ABL); p<0.001. The rate of overhangs varied among groups considerably with G1 and G3 having the highest rate (p<0.037).
