Abstract EN

Background : the overhanging margins are responsible for much iatrogenic periodontal disease.

May investigators found that high proportions of restorations have reported over hanging margins.

Materials and methods : the prevalence of overhanging margins and associated periodontal status in patients who attended periodontal department, college were assessed.

Results : the chance of a site bleeding on probing depended not only on the probing depth but directly on the presence or absence of an over.
