Recently, self-etching adhesive system have been developed and bonding procedures simplified into one or two steps, which are simultaneously applied to both enamel and dentin. These systems are easy to use and have the potential for good clinical success.

The purpose of this study is to evaluate in vitro the microleakage on the cementum/dentin and enamel walls in composite resin restoration of Class V cavities, regarding the use of different adhesive systems.

30 human premolars were divided into 3 groups. A standardized Class ¥´ preparation was prepared on the buccal and lingual surface of each premolar. The preparation were made parallel to the cementoenamel junctions, with the gingival half of the preparation extending 1mm apical to the cementoenamel junction. After adhesive system was applied to teeth as manufacture¡¯s recommendation, hybrid resin composite was filled in bulk into the preparation and light polymerized according to manufacturer¡¯s recommendations.

Specimen were stored in distilled water at 37¡É for 5 days and thermocycled 1000 times (5¡É+2¡É and 55¡É¡¾2¡É), then immersed in a 2% methylene blue solution for 12 hours. After sectioning mesio distally through the restorations, the degree of dye penetration was scored under a stereomicroscope at ¡¿ 25 magnification. The data were analyzed statistically using t-test and one-way ANOVA.

The results were as follows:

¡¤ There is no adhesive system which can prevent microleakage perfectly.

¡¤ There is significant difference in microleakage between enamel margin and dentin margin (p£¼0.0001).

¡¤ In enamel margin, self-etching primer systems did not show any significant difference comparing total-etching system.

¡¤ In denin margin, self-etching primer systems did not show any significant difference comparing one-bottle adhesive system used in combination with total-etching.
