Summary: | Introduction: Reflectivity of an object is a good parameter for
surface finish. As the patient evaluates finishing as a function
of gloss/reflectivity/shine an attempt is made here to evaluate
changes in surface finish with custom made reflectometer.
Aim: The aim of the present study was to study the effect of
various procedures during orthodontic treatment on the shine
of enamel, using a custom made reflectometer.
Materials and Methods: Sixty one extracted premolars were
collected and each tooth was mounted on acrylic block.
Reflectivity of the teeth was measured as compared to standard
before any procedure. One tooth was kept as standard
throughout the study. Sixty teeth were acid etched. Reflectivity
was measured on custom made reflectometer and readings
recorded. Same procedure was repeated after debonding. Then
60 samples were divided into three groups: Group 1 - Tungsten
Carbide, Group 2 - Astropol, Group 3- Sof-Lex disc depending
upon the finishing method after debonding and reflectivity was
measured.
Results: The mean percentage of reflectivity after acid etching
was 31.4%, debonding 45.5%, Tungsten carbide bur finishing
(Group 1) was 58.3%, Astropol (Group 2) 72.8%, and SofLex disc (Group 3) 84.4% as that to the standard. There was
statistically very highly significant (p<0.001) difference in
reflectivity restored by the three finishing materials in the study.
Thus, the light reflection was better in Group 3> Group 2>
Group 1.
Conclusion: The primary goal was to restore the enamel to its
original state after orthodontic treatment. The methods tested
in this study could not restore the original enamel reflectivity. |
