Comparative Evaluation of Adhesion of Strepto-coccus mutans on Figaro crowns in primary mo-lars - A Randomised Controlled Clinical Trial

Abstract

Introduction- Figaro Crowns placed into the oral cavity has the potential to create a niche for adhesion of the micro-organisms on to the surface of the crown, which in the due course can result in various complications. As there are no studies in the literature reporting the bacterial adhesion on Figaro crowns in primary teeth, the aim of the present study was to comparatively evaluate the adhesion of streptococcus mutans on Figaro crowns with that of the stainless-steel crowns in primary molars. Materials and Method- 30 children between the ages of 6- and 9-years requiring pulp therapy and crowns in bilateral mandibular second primary molars were included in the trial and were randomly allotted with Figaro crowns and stainless-steel crowns. Plaque samples were collected from the surfaces of the crowns at baseline, 3 months, 6 months, 9 months and 12 months ans were subjected to microbiological analysis for estimation of streptococcus mutans levels. The streptococcus mutans levels were estimated in colony forming units and were subjected to statistical analysis. Results- At baseline and 3 months there is no significant difference in the S.mutans count with Figaro crowns and stainless steel crowns, however, at 6, 9 and 12 months a statistically significant reduction in the S.mutans count is noticed with Figaro crowns (P value =0.01, 0.02, 0.04 respectively). Conclusion- There is a significantly decreased adhesion of the Streptococcus mutans on the Figaro crowns over a period of time.
