Study of Microleakage between Material Restoration Glass Ionomer Cement and Alkasite in Class V Cavity (G.V. Black)

Abstract

Microleakage is a gap between the surface of the tooth and the restoration caused by the failure of the restoration. Glass Ionomer Cement (GIC) and Alkasite are materials with good clinical appearance, but the mechanical strength of GIC was lower than Alkasite and the microleakage occurs in both restorations. Purpose: This study aims to determine the microleakage between GIC and Alkasite restorations in the Class V cavity for 1 day, 7 days, and 30 days after restoration in the tooth. Materials and methods: This study used 30 maxillary premolars and was divided into six groups. Group A restored by GIC and group B by Alkasite. Groups A1 and B1 were restored and incubated for 1 day, groups A2 and B2 for 7 days, groups A3 and B3 for 30 days. All specimens were incubated at 37ºC and isolated with nail varnish except for the restored areas before immersion with 1% methylene blue at room temperature for 1 day. The specimens were cleaned and cut longitudinally, then observed by a stereomicroscope and scored 0-4. Results: Average values of GIC and Alkasite microleakage after 1 day were greater than 7 days and 30 days. a Comparison of the average microleakage values of GIC and Alkasite shows microleakage values of GIC are greater than Alkasite. However, statistical analysis test results showed that there were no significant microleakage values between GIC and Alkasite after 1 day, 7 days, and 30 days (p> 0.05).
