Abstract
© 2013 Wiley Publishing Asia Pty Ltd. AIM: To observe the effects of glass-ionomer cement (GIC) lining on the risk of pulpal complications in deep occlusal cavities with resin-based restorations.METHODS: Fifty-three patients, aged 18-30 years, who had one or two deep occlusal carious lesions (≥3 mm in depth) in molars, were recruited. Dental caries were removed, and the prepared cavity was restored with resin composite using one of two restorative procedures: (a) without GIC lining; and (b) with (resin-modified) GIC lining. Restored teeth were evaluated for any pulpal complications (subjective symptoms, objective signs or loss of tooth vitality) at 1 month (baseline), 1 year, and 2 years after restoration.RESULTS: After excluding shallow cavities, 31 restorations without GIC lining, and 31 restorations with GIC lining, were placed and recalled at baseline without any pulpal complications. At the 1- and 2-year recalls, six patients who had restorations in group 1, and 13 in group 2, had dropped out. None of the remaining teeth in the two groups exhibited pulpal complications at either recall period, regardless of GIC lining placement.CONCLUSIONS: The absence of GIC lining does not increase the risk of pulpal complications in deep occlusal cavities restored with resin-based restorations in either the short or long term.
