Abstract:

BACKGROUND: Glass ionomer cement is a kind of new dental material. It has strong adhesiveness, low irritating, which is perfect to prevent dental caries. Currently, glass ionomer cement has been widely used in dental filling, adhesive, hole-lining, dentin hypersensitivity and temporary sealing.
OBJECTIVE: To compare the repair effects of light-cured glass ionomer and resin reinforced glass ionomer on dental restoration.
METHODS: Forty-eight dental caries patients were randomly divided into two groups: one group was repaired by light-cured glass ionomer and the other by resin reinforced glass ionomer. A follow-up of 6 months to 2 years was performed by comparison of integrityof the prosthesis, edge sealing, secondary caries and periodontal and endodontic lesions.
RESULTS AND CONCLUSION: The follow-up of 6 months showed that the successful rate was 97% in the light-cured glass ionomer group and 99% in the resin reinforced glass ionomer group was 99%. There were no significant difference between the successful rates of the two groups after follow-up for 6 months (P > 0.05). The follow-up of 2 years showed that the successful rate was 74% in the light-cured glass ionomer group and 92% in the resin reinforced glass ionomer group, and a significant difference occurred between the two groups (P < 0.05). The follow-up results displayed that the resin reinforced glass ionomer restoration is characterized as longer time to keep the integrity, better sealing, lower incidence rate of cervical caries and pulp and periodontal lesions. The material of resin reinforced glass ionomer is more convenient for the clinical use.
