Abstract
Objective: The purpose of this study was to increase success rate of sealant targeting C Product/3M Espe, T Product/Kuraray, U Product/Ultradent, and H Product/Ivoclar Vivadent AG as the light-cured sealants with high use frequency in the clinical.
Methods: It polymerized halogen curing unit ULTRA-LIRE 5 TUBO (ROLENCE ENTERRISE INC), plasma arc curing unit LIEXTN 685 (3M Espe, USA), and LED curing unit Elipar Freelight 2 (3M Espe, USA), evaluated the compressive strength and micro-leakage in each material according to light wave length, compared difference between each curing unit and material, and then carried out this experiment in order to be conducive to selecting proper material.
Results: U Product showed the highest compressive strength in light-source Plasma arc and LED. U Product and C Product showed high compressive strength in Halogen (p＜0.001). As for a result of measuring the micro-leakage according to light source in tooth surface depending on a kind of sealant, T Product and U Product showed low micro-leakage in Plasma arc (p＜0.001). As for a result of measuring the micro-leakage in tooth surface of sealant according to light source, Plasma arc showed the lowest micro-leakage in C Product, T Product, and U Product. Plasma arc and Halogen showed low micro-leakage in H Product (p＜0.001).
Conclusion: In consequence of the above experiment, the patients with strong occlusal force in the clinical application of sealant are recommended to polymerize U Product with LED. The patients as children with high probability of micro-leakage are recommended to use T Product as Plasma arc.
