Marginal integrity evaluation of resin pit and fissure sealant with different application techniques
Introduction: Marginal integrity can be defined as the ability of a sealant to establish a robust and resilient bond at the interface between the sealant and the tooth surface, preventing microleakage, discoloration, the formation of voids and cracks, and the subsequent development of caries lesions...

| description | Introduction: Marginal integrity can be defined as the ability of a sealant to establish a robust and resilient bond at the interface between the sealant and the tooth surface, preventing microleakage, discoloration, the formation of voids and cracks, and the subsequent development of caries lesions. Aim: To make a scanning electron microscopy (SEM) evaluation of the marginal integrity of resin sealant applied on the occlusal surfaces of permanent molars, using different techniques. Materials and methods: The study involved 80 non-carious human third molars that were subjected to three different sealant application methods: conventional, heating, and the use of a vibrating instrument. 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’s total length. Results: The data show that marginal adaptation ranges from 90% to 94% before thermocycling. Sealants’ 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 (p<0.001). The best sealant adaptation was observed when vibrations were applied along the fissure system. Conclusion: The method of sealant application plays a crucial role in determining its marginal integrity and sealing ability. |
