Long-term clinical evaluation of Dyract compomer in the restoration of non-caries cervical lesions: A 20-year retrospective study

Objective: The restoration of non-caries cervical lesions has long been a challenge. Until recently, compomers were the restorative materials of choice. The aim of this in-vivo study was to evaluate the long-term clinical performance of Dyract restorations in non-caries cervical lesions. Method and Materials: Forty-two patients with Dyract restorations of non-caries cervical lesions performed in 1995 by the same operator were included in this in-vivo retrospective study. After 20 years, restorations were evaluated by two calibrated examiners following the USPHS criteria modified by Ryge. Results: After 20 years, 38 of the 54 restorations included in this study remain in service (70.4%). Debonding was the cause of all failures. Marginal adaptation and marginal discoloration were the categories with poor values. Conclusion: Dyract restorations can be considered a treatment option for non-caries cervical lesions, because they show good long-term clinical performance for 20 years. Clinical Relevance: Dyract restorations continue to be an option to restore non-caries cervical lesions, due their good long-term clinical performance and the ease of the clinical procedure. The survival rate of these Dyract restorations was high after 20 years (70.4%). However, the limitations of marginal discoloration, marginal adaptation, and color match should be considered.
