Purpose: To investigate the effectiveness of Clearfil Liner Bond, Gluma 2000, and Scotchbond Multi-Purpose when applied in combination with proprietary restorative resins in V-shaped circular cavities which were cut in incisors either centrally on the labial enamel surface (Type 1) or labially crossing the cemento-enamel junction (Type 2). 

Materials and Methods: Forty teeth scheduled for extraction for periodontal reasons were treated in vivo and another 40 teeth in vitro. The in vivo restored teeth were extracted after 3 months of clinical service and the in vitro treated samples were stored in water for 1 week and thermocycled 250 times between 5 degrees C and 55 degrees C, prior to a 24-hour immersion in 0.5% fuchsin tracer solution of all specimens, sectioning and scoring interfacial dye penetration. 

Results: ANOVA revealed no significant differences between all in vivo samples sites, all in vitro enamel sites and the apical Type 2 sites of the Gluma samples. In contrast, the apical Type 2 leakage of CLB and SMP was significantly more pronounced, although not statistically different from each other. The results of the short-term clinical performance of the three systems was moderately more favorable than the laboratory microleakage test results.
