The effect of polishing methods of a material used in temporary crowns fabrication on gingival index. – (IN VIVO)

Abstract

 Aim of the study: this study aims to compare the gingival index when using a material to make temporary crowns, Temp C and B Ic from Transcen Company, after finishing their surface in three different ways  (composite finishing burs - rubber discs - coating with a bond).

Materials and Methods: The research sample consisted of thirty temporary crowns that were clinically applied by direct method on thirty teeth that need crows, divided into three groups:

The first: were finished with composite finishing burs (conical _ candle flame).

The second: were finished with rubber cones with a color gradient (green - yellow - white).

Third: were finished by coating with the bond.

A week after the placement and finishing  of the temporary crowns, the gingival changes that occurred in each of the previous groups were studied The teeth were examined clinically and by the periodontal probe.

Results: Results: The study showed that the finishing of temporary crowns by composite burs had increased the value of the gingival index

Conclusion: Within this study limits, we find that coating the temporary crown with a bond or using rubber cones in the finishing had a better effect

on the gingival inflammation index than the method of finishing  with composite burs.
