Abstract
In the present
study, two different fibre-reinforced composites (FRCs) (glass and
polyethylene FRC), dental ceramic and restorative composite were
compared with respect to early plaque formation in vivo. Disc-shaped
specimens were randomly distributed among the upper first and second
molars of 14 healthy adult volunteers. Plaque samples were collected 24 h
after the attachment of the specimens. Mutans streptococci (MS),
non-mutans streptococci and total facultative bacteria were cultured.
The plaque recovered from polyethylene FRC harboured significantly more
MS than the plaque of ceramic, restorative composite and glass FRC. For
the counts of non-mutans streptococci and total facultative bacteria,
polyethylene FRC showed the highest counts, and ceramic showed a trend
towards lower counts. The amount of plaque accumulation showed an
association to the earlier reported surface roughness values of the
studied materials. It was concluded that in the oral environment,
polyethylene FRC promotes plaque accumulation and adhesion of MS more
than glass FRC, restorative composite and dental ceramic. Glass FRC
resembles restorative composite with respect to plaque accumulation and
the adherence of MS.
