The purpose of this study was to report the 2-year clinical evaluation of the use of a gingiva-coloured composite, Amaris Gingiva, (Voco, Germany) for restoration of cervical defects on permanent human teeth. The study included 16 patients with 128 restorations of cervical lesions arisen as a result of either gingival recession or worn root dentin. They were complaining from non-aesthetic appearance and hypersensitivity to cold. The old restorations were replaced or all defects were treated with the gingiva-colour composite at corresponding gingival areas, while rest of the cavities were filled with a pre-polymerized micro-hybrid tooth-coloured composite (Amaris, Voco, Germany). These combined restorations were evaluated by 2 examiners at baseline, 6, 12 and 24 month intervals using USPHS criteria for colour stability, marginal discolouration, marginal adaptation, caries, anatomic form, surface texture, sensitivity and retention. The changes in parameters were assessed by Wilcoxon signed rank test at a significance level of 0.05. 117 restorations were reported with good retention in oral cavity at a 2-year recall. 2 restorations of the same patient were lost at the second month and scored as Charlie at the end of the study and lasted with prosthetic restorations. 7 restorations of other 4 patients were lost at fourthand tenth months and scored as Charlie at the end. The restorations were repeated for 3 patients and still survived by the end of a 2-year recall. 95 restorations were evaluated as excellent for colour match at 2-year recall. The restorations were scored as 9 Bravos and 4 Charlie for marginal discolouration, 7 Bravos for marginal adaptation and 5 Bravos, for anatomic form at the end of a 2-year recall (p<0.05). It appears that Amaris Gingiva as a gingiva-coloured composite seems an acceptable treatment choice for cervical defects with recessed gingiva, under the conditions of this longitudinal clinical study.
