Abstract
Abstract
Introduction: In modern operative dentistry in the field of pediatric dentistry Er,Cr:YSGG laser is suitable for cavity preparation in deciduous molars because it have many advantages. Microleakage is one of the major problems that influence the longevity for the resin-based dental restorations. The purpose of the current study is comparing the effect of Er,Cr:YSGG laser and conventional conditioning on the microleakage in cavity class V restored by composite resin and conventional flowable composite in deciduous molars.
Materials and methods: A standard class V cavity were prepared at the buccal or lingual surface of forty-eight freshly extracted caries-free human deciduous molars which were divided into 2 groups according to the mode of conditioning: group 1: by using Er,Cr:YSGG laser; group 2: by using conventional conditioning. The samples were subjected to thermocycling and dying step.
Results: Laser conditioning showed statistically significantly lower median microleakage scores than conventional technique (P-value = 0.001, Effect size = 1.923) and (P-value = 0.002, Effect size = 1.639), respectively. There was no statistically significant difference between median microleakage scores of the two composite types (P-value = 0.057, Effect size = 0.718) and (P-value = 0.108, Effect size = 0.658), respectively.
Conclusion: Conditioning by Er,Cr:YSGG Laser is better than conventional method as regards microleakage and no significant difference between composite resin and conventional flowable composite clinically.
