Effect of protective coating on microleakage of conventional glass ionomer cement and resin-modified glass ionomer cement in primary molars: An In vitro study. Indian Journal of Dental Research. 2018 Nov; 29(6): 744-7480970-92901998-3603http://imsear.searo.who.int/handle/123456789/192150The aim of this in vitro study was to evaluate and compare the effect of protective coating G-Coat Plus on microleakage of conventional glass ionomer cement (CGIC) and resin-modified glass ionomer cement (RMGIC) in primary molars. Materials and Methods: A total of 120 samples were divided into four groups with 30 samples in each group. Group A – teeth restored with CGIC. Group B – teeth restored with CGIC coated with G-Coat Plus. Group C – teeth restored with RMGIC. Group D – teeth restored with RMGIC coated with G-Coat Plus. Microleakage was tested using 2% basic fuschin dye penetration and measured at ×40 original magnification under the stereomicroscope. Results: The results of this in vitro study showed that coating with G-Coat Plus showed a reduction in microleakage in CGIC and complete absence of microleakage in RMGIC when compared to the noncoated groups, which was statistically significant. CGIC without G-Coat Plus showed highest microleakage followed by RMGIC without G-Coat Plus, followed by a relatively less microleakage in CGIC with G-Coat Plus. Conclusion: Significant reduction in microleakage was seen in conventional GIC and RMGIC with G-Coat Plus when compared to conventional GIC and RMGIC without G-Coat Plus.Conventional glass ionomer cementG‑Coat Plusmicroleakageprimary molarsresin‑modified glass ionomer cementEffect of protective coating on microleakage of conventional glass ionomer cement and resin-modified glass ionomer cement in primary molars: An In vitro studyJournal ArticleIndiaDepartment of Pedodontics and Preventive Dentistry, Chettinad Dental College and Research Institute, Rajiv Gandhi Salai, Kelambakkam, Kanchipuram, Tamil Nadu, IndiaDepartment of Pedodontics and Preventive Dentistry, Sathyabama Dental College and Hospital, Kelambakkam, Kanchipuram, Tamil Nadu, IndiaDepartment of Pediatric and Preventive Dentistry, Meenakshi Ammal Dental College, Chennai, Tamil Nadu, India
