Residual Pumice: Assessing a Potential Contaminant in Orthodontic Bonding
Abstract
To assess the effect of clinically-observed residual prophylaxis pumice on orthodontic shear bond strength when using a self-etching primer bonding protocol. Materials and Methods: 100 bovine teeth were randomly divided into five groups (N=20)according to prophylaxis protocol: control (no pumice prophylaxis), pumice flour with mechanical debridement, pumice flour without debridement, pre-mixed pumice with mechanical debridement, and pre-mixed pumice without mechanical debridement. After prophylaxis, brackets were bonded using a self-etching primer bonding technique (3M Unitek TransbondPlus Self-Etching Primer). Samples were tested for bond strength 48 hours after bonding using a universal testing machine. Data were analyzed using analysis of variance (ANOVA) with significance level at 0.05.
