[A clinical evaluation of filling radiation caries].

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.
