Abstract

Purpose: To evaluate the role of compomers in secondary caries formation in vitro. Materials and Methods: 36 human teeth with caries-free enamel (coronal) and root surfaces underwent a fluoride-free prophylaxis. Class V cavities were prepared in buccal and lingual coronal and root surfaces. The teeth were divided into two groups with 3 treatment subdivisions [12 teeth perrestorative material (6 with coronal restorations and 6 with root surface restorations)]). The preparations were restored with: (1) filled composite (Filtek Z250 with Single Bond), (2) fluoride-releasing compomer [Hytac withPrompt L-Pop (fluoride-releasing water-based adhesive)]; or (3) fluoride-releasing compomer [Dyract AP with Prime & Bond NT (fluoride-releasing acetone-based adhesive)]. 24 cavities (6 teeth with 2 cavities/tooth) were available with each treatment. The teeth were thermocycled (500 cycles at 5-50 degreesC) in synthetic saliva prior to artificial caries formation. After lesion formation, 5 longitudinal sections were taken from each specimen for polarized light evaluation. Mean surface lesion depths and wall lesion frequencies were determined. Results: The Filtek Z250 group had significantly (P<0.05, ANOVA, DMR) greater mean body of the lesion depths in coronal (205 <mu>m) and root surfaces (221 mum) than either the Hytac (119 mum coronal and 161 mum root surfaces) or the Dyract AP (127 mum coronal and 149 mum rootsurfaces) groups. Likewise, wall lesion frequency was significantly higher(P<0.05, ANOVA, DMR) for the Filtek Z250 group (41% coronal and 37% root surfaces) compared with either the Hytac (31% coronal and 25% root surfaces)or Dyract AP (26% coronal and 21% root surfaces) groups. No differences inouter body of the lesion depths or wall lesion frequencies were found between Hytac and Dyract AP for coronal and root surface restorations (P>0.05, ANOVA, DMR).
