Abstract
Objective: The purpose of this study was designed to compare surface roughness of zinc containing glass ionomer to metal modified glass ionomer and the conventional glass ionomer cements, in vitro study. Influence of different pH on this parameter as well as effect of difference storage periods on the previous variables. Evaluation of new modified zinc glass ionomer (Chemfil rock) and choice of restoration in acidic consumption patients.
 
Material  and  methods:  Three  equal  groups  of  45  discs  each. A zinc  reinforced  glass ionomer restoration (Chemfil rock), silver reinforced glass ionomer restoration (Ketac silver), and conventional glass ionomer restoration (Ketac fill). Surface roughness (Ra) was measured with USB digital surface profile gauge. Data were collected to correlate the (Ra) under the influence to variable pH solutions.
 
Results: It was found that Chem-Fil group recorded statistically significant (P<0.05) highest roughness mean value (237.63 Ra) followed by Ketac-Ag group (219.47 Ra) while Ketac-Fil group recorded statistically significant (P<0.05) lowest roughness mean value (192.69 Ra) as indicated by multi-factorial ANOVA. Pair-wise Tukey’s post-hoc tests showed non-significant (p>0.05) difference between Chem-Fil and Ketac-Ag groups
Conclusions: For different period of time, we concluded that all tested material do not improve (Ra) regardless the Ph of storage media.
