Abstract
AIM OF THE STUDY: The aim of the study is to determine and compare the microleakage and marginal adaptation of three different glass ionomer cements in class v cavity using scanning electron microscopy analysis after thermocycling. MATERIALS AND METHODS: Marginal adaptation assessment was done in class V cavity for three different glass ionomer cements under invitro conditions. Group 1: Fuji Ix (Control), Group 2: Zirconomer Improved, Group 3: Riva Self Cure, Group 4: Xtracem-S). 40 freshly extracted human mandibular single rooted premolars were used in this study. Class v cavity prepared on the buccal and lingual surfaces of each tooth measuring 3mm wide mesio-distally, 2mm wide occluso-gingivally and 1.5mm deep. Selected samples were randomly divided into four groups of 10 teeth each, and prepared class v cavities restored. The restored teeth were subjected to thermocycling and sectioned longitudinally in a bucco-lingual direction through the center of the restoration. These sections were then examined with a scanning electron microscope under magnification of 1000x. The structure analyzed was the tooth restoration interface in the occlusal and gingival margins. RESULTS: Marginal gap measurement values were tabulated and statistically analysed. Xtracem-S (GROUP 4) showed least microleakage among the four glass ionomer cements at the significant level, (p<0.01) followed by Riva self cure (GROUP 3), Zirconomer improved (GROUP 2) and Fuji IX (GROUP 1). Highest microleakage was seen with Fuji IX (CONTROL GROUP). CONCLUSION: Xtracem-S (GROUP 4) and Riva self cure (GROUP 3) showed comparably least microleakage in this study. Highest comparable microleakage was seen in Fuji IX (GROUP 1) and Zirconomer Improved (GROUP 2).
