In Vitro Evaluation Of Microleakage Around Amalgam Restorations By Using Two Different Liners
Yıldırım H. BAĞIŞ*, Adil NalçacI*, Çağlar YOLDAŞ*, Pırıl TunakanlI*
Purpose: The aim of this in vitro study was to compare the
microleakage around Black Class ll amalgam restorations using three different lining materials.
Material and Method: For this aim, amalgam restorations prepared after using Clearfil Liner Bond ll and Amalgam Liner were
compared with unlined amalgam restorations. 30 permanent noncarious human molar teeth extracted for periodontal and prosthetic reasons were used. Ten teeth were randomly
assigned for each of the three experimental group. Black Class II MO cavities in confinement of enamel were prepared. Amalgam restorations were prepared by using the liners as suggested by manufactures. One experimental group was
finished without liner. The specimens were stored in the distilled water at 37 OC for 3 months. 200 x thermocycling was applied between 5 ±2 for one minute and 55 ±2 for one minute. After this procedure the apices of the teeth were covered with light cure composite and each specimen was sealed with two layers of nail varnish leaving 2 mm space around the restorations. Then the teeth were submerged in 0.5 % basic fuchsine for 24 hours. The teeth were sectioned in the mesio distal direction. The specimen were then evaluated for staining patterns under steromicroscope and photographs were taken.
Results: Microleakage results were evaluated significantly by using Khi-Square test. The statistical analysis indicated that Clearfil Liner Bond II showed better microleakage results than Amalgam Liner and unlined restorations (p<0.05). No statistical differences were obtained between occlusal and gingival cavity among the test groups.
Conclusions: The results show that none of the experimental groups eliminated the microleakage completely. But less
microleakage was observed in the liner applied amalgam restorations then unlined restorations. Clearfil Liner Bond II
significantly reduced microleakage when compared to Amalgam Liner and unlined amalgam restorations.Keywords: Microleakage, amalgam liner, bonding, AmalgamTurkiye Klinikleri J Dental Sci 1997, 3:89-93
