Comparative Evaluation of GC Gold Label IX with GC Gold Label IX Extra and GC Gold Label Hybrid in Cavitated Lesions Prepared by Hand Instrumentation Technique in Primary Molars: An In Vivo Study

Original rESEarCHhigh molecular weight polyacrylic acid along with the conventional polyacrylic acid, which has been claimed to show improved mechanical and handling properties.It has comparably high shear bond strength to dentin and shows acceptable marginal adaptation and reduced microleakage compared to conventional GICs. 7The fine size of fluoroaluminosilicate glass particles has also led to improved optical properties of the material.The small size of the glass particles minimizes collision against visible light waves, allowing light to penetrate through the restorative material.This improves the esthetic appeal as the material appears more translucent. 6herefore, the present study was undertaken with the aim to compare the clinical efficacy of GC Gold Label IX, GC Gold IntroductIonPediatric restorative dentistry provides clinicians with guidance to form decisions about techniques and materials appropriate for pediatric patients.Restorative treatment of carious teeth is essential to stop disease progression.Different approaches are available for the excavation and restoration of carious lesions. 1 Caries removal using the air rotor is sometimes associated with patients' discomfort and pain. 2 An effective alternative would be to use simple hand instruments, seeking to make the environment more comfortable for the child patient.Hand excavation technique is one of the noninvasive methods, which is considered to be a patient-friendly treatment, especially for young children. 3uring caries removal, caries-detecting dyes aid in the clinical differentiation of the infected dentin from the affected dentin. 4aries detector dye (Kuraray International Limited) is composed of two components, that is, 1% acid red 52 dye (sulforhodamine B) and propylene glycol. 5As the dye targets the demineralized collagen rather than bacteria, it provides a reliable method of preserving the remineralizable affected dentin and facilitates the removal of only infected dentin. 4lass ionomer cements (GICs) are one of the most commonly used restorative materials in pediatric dental practices. 6High viscosity GICs (HVGIC) are claimed to have better mechanical properties.A novel self-adhesive material, GC Gold Label Hybrid GIC, is a recently introduced hand-mixed cement featuring glass hybrid technology.The glass hybrid restorative system is reinforced with ultrafine, highly reactive glass particles.
