ERRATUM
In Operative Dentistry 33(2) 196–202, Class I Gap-formation in Highly-viscous Glass-ionomer Restorations: Delayed vs Immediate Polishing, the name of co-author Goro Nishigawa, DDS, PhD was mis-spelled. Nishigawa is the correct spelling.
Also in Operative Dentistry 33(2), on page 219 of the Buonocore Memorial Lecture, Figures 10 and 11 were inadvertently printed as the same. The corrected Figure 10 is shown below. Operative Dentistry apologizes for this error.
