RESIN-MODIFIED GLASS IONOMER: Authors' response

Abstract

We appreciate Dr. Croll's concerns with our statements regarding lack of effectiveness for resin-modified glass-ionomer (RMGI) liners. In response to his question, we consider vital teeth as having sensitivity to cold and heat and little sensitivity to air flow, and hypersensitive teeth as having an exaggerated response to cold, heat or air stimulation (we tested cold and air). RESIN-MODIFIED GLASS IONOMERThe Journal of the American Dental AssociationVol. 144Issue 11PreviewUpon reading the ”Conclusions“ section of Dr. Brad Strober and colleagues' August JADA article, ”Effectiveness of a Resin-modified Glass Ionomer Liner in Reducing Hypersensitivity in Posterior Restorations: A Study From the Practitioners Engaged in Applied Research and Learning Network“ (Strober B, Veitz-Keenan A, Barna JA, et al. JADA 2013;144[8]:886–897), I was astounded that the authors wrote, ”These findings suggest that the time, effort and expense involved in placing an RMGI [resin-modified glass ionomer] liner in RBC [resin-based composite] restorations may be unnecessary, as the representative liner used did not improve hypersensitivity outcomes.“ Full-Text PDF
