One-year clinical evaluation of two composite materials used for anterior class V restorations

The purpose of the current study was to evaluate the clinical performance of two composite materials used for filling anterior cavity preparations. A total of 100 class V cavities of anterior tooth were restored with two different composite materials (Palfique Estelite and Palfique Toughwell, 50 cavities each, respectively) in combination with the same bonding agent (Mac Bond II). Colour match, cavosurface marginal discolouration, recurrent caries, wear, marginal integrity and surface texture were evaluated clinically for all restorations on the basis of the United States Public Health Service (USPHS) criteria immediately after insertion (baseline), after 6 months and after 1 year. In the comparison of baseline to 1-year evaluation, the Palfique Toughwell material showed significant changes in all factors except recurrent caries. The Palfique Estelite material, however, showed neither significant cavosurface marginal discolouration nor recurrent caries. No significant difference (P > 0b05) was observed between the two materials in clinical performance after 1 year, with the exception of caries rate, which was found to be significantly lower in the Palfique Estelite material. It was concluded that both composites were clinically reliable materials when used for anterior class V restorations.
