ObjectiveTo compare the effects of photosensitive resin, reinforced glass ionomer and sliver amalgam filling in the treatment of primary tooth caries.
MethodsA total of 125 patients with primary tooth caries were selected as the study subject, and were divided into group A (n=43, 106 caries), group B (n=42, 102 caries) and group C (n=40, 98 caries) according to the different filling treatment methods.The group A was filled with photosensitive resin, group B was filled with reinforced glass ionomer, and group C was filled with sliver amalgam.The filling time of each tooth, incidence of dentin hypersensitivity reaction, retention of filling materials and caries recurrence in the three groups were compared.
ResultsThe filling time of each tooth in group A was shorter than that in group B and group C (P < 0.05), and which in group B was shorter than that in group C (P < 0.05).The incidence of dentin hypersensitivity reaction at one week after filling treatment in group A was lower than that in group B and group C (P < 0.05), and which in group C was lower than that in group B (P < 0.05).The complete retention rate of filling materials at one week after filling treatment in group A was higher than that in group B and group C (P < 0.05), and the difference of which between group B and group C was not statistically significant (P>0.05).The caries recurrence rate at 6 months and 1 year follow-up in group A and group C was lower than that in group B (P < 0.05), and the difference of which between group A and group C was not statistically significant (P>0.05).
ConclusionsCompared with reinforced glass ionomer and sliver amalgam, photosensitive resin filling in treatment of primary tooth caries has shorter filling time, lower incidence rate of dentin hypersensitivity, higher retention rate of filling materials, and lower caries recurrence rate.
