Results
A total of 58 lesions in 47 older adults were enrolled in this study. The plaque attachment rates tended to be lower in the material-coated root surfaces than in the healthy exposed root surfaces after 3, 6, and 12 months, although the differences among the three groups were not significant. Moreover, the coating material fall-out rate tended to be lower in the Caredyne group than in the Fuji VII group. There was no significant difference in the failure rate among the three groups at the 12 months mark.
