Summary

Overhanging dental amalgam restorations are highly prevalent (64.12%), significantly increasing periodontal pocket depth and bone loss. These findings highlight the link between restoration overhangs and periodontal disease progression.

Area of Science:

  • Dentistry
  • Periodontology
  • Restorative Dentistry

Background:

  • Dental restorations, particularly Class II silver amalgam fillings, are common.
  • Overhanging margins of these restorations may pose risks to periodontal health.

Purpose of the Study:

  • To determine the prevalence of overhanging Class II silver amalgam restorations.
  • To investigate the association between these overhangs and periodontal health indicators.

Main Methods:

  • A cross-sectional study was conducted on patients at two dental colleges.
  • Evaluated pocket depth and bone loss in relation to overhanging restorations versus unrestored teeth.

Main Results:

  • A high prevalence of overhanging restorations (64.12%) was observed.

  • Restored surfaces with overhangs showed increased mean pocket depth (3.75 mm vs. 3.46 mm) and bone loss (1.64 mm vs. 1.50 mm) compared to unrestored contralateral teeth.

    • Conclusions:

    • Overhanging Class II silver amalgam restorations are common and linked to periodontal disease.
    • Restoration overhangs contribute to periodontal breakdown, evidenced by increased pocket depth and bone loss.
