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
치면열구전색제의 도포 시 발생하는 기포는 전색제의 두께 감소에 의한 강도의 저하로 파절 및 마모를 일으킬 수 있으며 특히 계면부에 발생한 경우 미세 누출 등의 임상적인 문제점을 가져온다. 본 조사에서는 치면열구전색제 중 Teethmate
