Title	An in vitro comparative evaluation of microleakage in open sandwich technique in Class V restoration (Adye penetration study).

Creator	Khadhim, Alaa J.

Description	Background: The purpose of this in vitro study was to compare the microleakage at dentin margins of class V cavities filled with compomer alone and compomer lined with conventional glass ionomer cement or resin modified glass ionomer cement. Materials and Methods: fifteen recently extracted human premolars were prepared with standardized box shaped class V cavities of 3.0 mm (mesial-distal), 2.0 mm (occlusal-gingival), and 2.0 mm depth with margins located on enamel and dentin/cementum on the buccal or lingual surfaces. The cavities were randomly assignedinto three groups (n=10): Group I –compomer Dyract extraDetsply DetryGmbH (control); Group II – compomer Dyract extraDetsply DetryGmbH lined with conventional GIC (promedica Medifil). Group III – compomer Dyract extra Detsply DetryGmbH lined with RMGIC (3M ESPE Vtrebond). After being immersed in tap water for 24 h, the specimens were thermocycled (500 cycles, 5°-55°C, 30 sec dwell time) and immersed in a 0.5% basic fuchsine solution for 24 h. The restorations were sectioned longitudinally and gingival margins were evaluated for microleakage using a 0-4 scale. Data were subjected to the Kruskal-Wallis test and Mann-Whitney U tests at p
