A two-year evaluation of four different fissure sealants.
OBJECTIVE
To evaluate fissure sealants based on Bis-GMA [Fissurit F (FF) and Fissurit FX (FFX)], compomer [Dyract Seal (DS)] and ormocer [Admira Seal (AS)] with respect to retention, marginal integrity and presence of caries after a 2-year period of follow-up.


METHODS
80 children aged 7-13 years (mean age: 9.4 + 1.3 years), were included, giving a total of 320 first permanent molars for the study units. Clinical evaluation of the sealants was carried out to assess retention, marginal integrity and presence of caries at 12 and 24 months after initial treatment.


RESULTS
Retention of compomer-based DS sealant was significantly lower than that of the others at the 12- and 24-month follow-up examinations (12 month, P<0.000; 24 month, P<0.006). No significant differences between the sealants were observed in marginal integrity (12 month, P>0.473; 24 month, P>0.069) or presence of caries (12 month, P>0.055; 24 month, P>0.777) at any follow-up examination.


CONCLUSIONS
While sealants composed of different resin matrices showed differences in retention, they were similar with respect to marginal integrity and presence of caries. Surface conditioning and the organic structure of the material are factors that may affect sealant retention.
