    Abstract:
    Four different glass-ionomer materials were evaluated for coronal microleakage in permanent lingual access restorations of endodontically treated anterior teeth. Forty extracted human anterior teeth were randomly divided into four groups following chemomechanical preparations and obturations with gutta-percha and sealer. Logobond, Aqua Ionobond, Ionoseal and Ketac-Cem were placed in 2 mm thickness over the gutta-percha obturation from cemento-enamel junction. Eight teeth were used as negative and positive controls. The teeth were thermocycled, coated with nail varnish and paraffin except around the access preparation. Next they were placed in dye and cleared to allow visualization of dye penetration. There was a tendency for the Ketac-Cem group to lack least but there were no statistically differences among the groups.
