Share Abstract:

A comparative analysis of techniques of restoring cervical lesions


Pages: 553-559
PMID: 8272493

There are several methods of restoring cervical abrasion or erosion lesions, including the use of composite resin, glass-ionomer cement, or a combination of these materials. This paper reports the effectiveness of three different materials and techniques in restoring cervical lesions, using marginal leakage as the means of comparison. Wedge-shaped cervical cavities were preapred so that the gingival cavosurface margin of each cavity involved dentin. Half of the specimens in each group were thermocycled. Differences in marginal leakage were more pronou nced at the gingival margin. There was no significant difference between the leakage of thermocycled and nonthermocycled specimens. Microleakage can be expected to be minimal in cavities restored with the sandwich technique, in which a glass-ionomer cement liner and composite resin restorative material are placed.
