COMPARATIVE CLINICAL EVALUATION OF THE QUALITY OF SOME LONG TERM AMALGAM AND TOOTH COLOURED RESTORATIONS
Abstract:
The aim of the study is to comparatively
evaluate the quality of consequent obturations. Material
and method: Four hundred and sixteen patients aged 15
to 65 were included into the study. From the 3731
restorations examined, 1027 (27, 53%) were amalgam
restorations and 2704 (72, 47%) were tooth coloured
restorations, placed in all cavity classes. Results:
Between ages 15-25 years, tooth coloured restorations
(520) were mostly found, compared to only 260 for ages
between 55-65 years. Concerning the number of amalgam
restorations (299) there has been noticed a relatively
equal weight of between 1st and 2nd class cavities. The
marginal adaptation of amalgam restorations has proved
to be incorrect in 455 cases out of 1027, and in 858 cases
out of 2704 for the tooth coloured restorations. The oral
hygiene mostly influences the quality of the tooth coloured
restorations. Conclusions: Tooth coloured restorations
tend to replace the amalgam, although this remains a
viable option. The existence of a large number of
inadequate restorations is due to an incorrect preparation
of the cavities the incorrect restoration technique and
inadequate oral hygiene.
