Epoxy resin replicas were created from each occlusal surface of the teeth. The teeth underwent thermocycling, after which new replicas were made. All replicas were coated with gold powder and observed under scanning electron microscopy. Marginal integrity of the replicas was assessed and compared before and after the thermocycling process. The extent of gaps was measured as a percentage of the restoration edge\u2019s total length.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results<\/jats:bold>\n                    : The data show that marginal adaptation ranges from 90% to 94% before thermocycling. Sealants\u2019 marginal adaptation was compromised in all study groups and decreased between 81% and 88% after thermocycling. There were statistically significant differences between the control and the other three groups in the study (heating and application of vibrations) before and after thermocycling (\n                    <jats:italic>p<\/jats:italic>\n                    &amp;lt;0.001).
