Objective:
To evaluate the clinical effects of filling for radiation carious cavities.
Methods:
146 carious cavities of 15 patients after radiotherapy for head and neck malignancies were included and were filled with two new GIC (Ketac-Molar and Fuji IX). The 2 years follow-up results were evaluated with USPHS evaluation criterion.
Results:
(1) The 2 years excellent rates were 51.7% in Ketac-Molar and 52.3% in Fuji IX, no significant differences. (2) Failures and defects were mainly occurred after 1 and 2 years. The main reason of failure was loss of filling. Marginal staining was a common shortcoming of the two materials. (3) There were no significant differences in main indexes except retention.
Conclusions:
It is successful for radiation caries to be filled with Ketac-molar and Fuji IX, and is practically significant in stomatological clinic.
