Uses of Glass ionomer cements in dentistry

A total of 60 teeth were divided into different groups. Extracted teeth were included in the present study. Each experimental group consisted of 10 embedded teeth. They were classified as according to material transbond XT, GC fuji ortho LC, GC fuji ortho, gic as luting agent, EQUIA forte and EQUIA fil. Teeth were given conditions accordingly as dry, wet also the surface treated was conditioned or unconditioned. The cement with luting properties was taken as sample of 10 teeth showing luting of capping a crown was also considered. The data was collected and evaluated. Results obtained were carefully studied an compared. Complete analysis was done using SPSS software. Results: Wet or dry conditioned surfaces, however, produced higher shear bond strengths than unconditioned wet or dry surfaces. The mean shear bond strength for fuji ortho LC dry conditioned and GC fuji ortho dry unconditioned at 24 hour was 13.45 and 3.06, at 7 days was 15.40 and 4.02. The shear bond strength for glass ionomer cement in capping material was 6.00. The mean stress at maximum load for EQUIA forte was 197.36 and for EQUIA coating was 170.33.Conclusion: Glass ionomer cements provide sufficiently high shear bond strengths as capping agent, restoration and in orthodontic brackets under clinical conditions.
