Abstract
In clinical practice, air bubbles trapped in the pit and fissure may increase early loss of sealing materials for fracture, wear and microleakage. The purpose of this investigation was to examine the bubble behavior of pit and fissure sealant. The 140 replicas made of epoxy resin were used to this experiment. Following conditioning, light-polymerized sealants were applied and then exposed to the light source. After stereoscopic examination of standarized specimen by grinding, bubble behavior was analysed. The results obtained were as follows; 1. Ultraseal XT® plus grops irrespective of using time were higher than groups of Heliosea® with clinpro tip and metal tip in the frequency of bubble(p<0.05), 2. Ultraseal® plus old group was more than Clinpro®, Teethmate F-l® and Helioseal® with brush tip in the number of bubble under 200 magnified cross section(p<0.05). 3. The widest mean area of bubble was shown in the Teethmate F-1®. 4. No statistically significant difference of the frequency and the site of bubble between Clinpro® and Helioseal® groups(p>0.05).
