The purpose of this study was to evaluate in vitro the shear bond strength to enamel, flexural strength, flexural modulus, and contraction stress of one orthodontic composite and two flowable composites. Orthodontic brackets were bonded to 45 human maxillary premolars with the composites Transbond XT, Filtek Z-350 flow and Opallis flow and tested for shear bond strength. For measurement of flexural strength and flexural modulus, specimens were fabricated and tested under flexion. For the contraction stress test, cylindrical specimens were tested and an extensometer determined the height of the specimens. The data were subjected to one-way ANOVA and Tukey's test (α=0.05). The shear bond strength values were significantly lower (p<0.05) for the flowable composites compared with the orthodontic composite. For the flexural strength, no statistically significant difference was found among the composites (p>0.05) while the flexural modulus was significantly higher (p<0.05) for Transbond XT than for Filtek Z-350 flow and Opallis flow. The orthodontic composite presented significantly lower contraction stress values than the flowable composites (p<0.05). The light-activated orthodontic composite material presented higher flexural modulus and shear bond strength and lower contraction stress than both flowable composites.

The Subject

Fetal reactivity to acoustic stimulation is a long-recognized phenomenon. Obstetrical interest in this phenomenon is usually considered to have begun with peiper’s report in 1925 of marked fetal movements following a pulsed, loud sound. Occasional attention to the subject was given in the subsequent five decades. Read and Miller are often credited with writing the first comprehensive clinical study of the usefulness of acoustic stimulation in evaluating fetal health. A clear finding in this study was the correlation between an abnormal contraction stress test and faliure of the fetus to respond to stimulation.
