Secondary caries is one of the most important factors leading to replacement of dental restorations. This investigation assessed the capacity of fluoride‐releasing restorative materials to resist cariesin vitrowhen used in roots. Class 5 cavities were prepared in the buccal and lingual surfaces of 30 extracted premolars. The six materials used were: glass–ionomer cement (Fuji ® ), glass–ionomer cement with silver particles added (Ketac‐silver ® ), fluoride‐containing composite resin (Tetric ® ), composite resin (Silux plus ® ), fluoride‐containing amalgam (Fluor‐Alloy ® ) and high‐copper amalgam (Dispersalloy ® ). After 5 weeks in an acid gel for caries‐like lesion formation, the teeth were sectioned longitudinally and examined with polarized light. The results showed that repair with glass–ionomer materials of a carious lesion may be of great importance in the prevention of secondary caries around the restorations in roots.
