Bacterial adhesion of Streptococcus mutans to cobalt chromium recast alloys

Cobalt chromium (CoCr) alloys are utilized to make dental prosthesis. Casting CoCr is a common operation in dentistry laboratories due its low cost. surplus (metal remaining the sprue and crucible former) frequently reused by reduce recycle metal waste. However, quality safety of these recast require further information. Microbial attachment surface prostheses may affect safety. Biofilm formation on can cause biocorrosion secondary infection. The effects different proportions Chromium alloy bacterial adhesion not clear. purpose this study was investigate how recasting affects Streptococcus mutans (S. mutans) adhesion. Twenty disk-shaped specimens (n= 20, allocated for 5 groups) were prepared from (Remanium GM; Dentaurum) with (100% new alloy, 25% 50% 75% 100% alloy). After immersion suspension 24 hours, number bacteria that adhere specimen’s counted using Colony Forming Units. Data analyzed one-way ANOVA (α = 0.05). significantly affected (p < An increased proportion showed an increase S. specimen surface.
