An Initial Assessment of the Effect on Orthodontic Pliers of Various Sterilization/Disinfection Regimes

Abstract

Duplicates of six commonly used orthodontic instruments were allocated to four groups. One of the groups of instruments was stored as a control. The three other groups were exposed to different regimes of sterilization or cold disinfection over an extended period. Twenty characteristics of function, corrosion, and appearance were then judged by four observers twice using a visual analogue scale of 100 units. No statistical evidence was found of routine autoclaving causing more damage to pliers than cold disinfection; in fact, the data suggested the contrary. Chrome plated pliers appeared more resistant to damage and maintained their appearance better than stainless steel pliers.
