Adhesion in pediatric dentistry

Abstract

Adhesion is closely associated with coronal restoration, pit and fissure sealant, temporary fixation of a luxated tooth, and occlusal guidance in pediatric dentistry. Although better adhesion is a desired clinical factor, attention to moisture exclusion is more important. Oral cavities of children are small and saliva secretion is abundant. Therefore, rubber dam isolation is always carried out in pediatric dentistry. It is necessary to consider the smallness of adhesion areas caused by thin enamel and dentin and the attrition of enamel. Caries activity of a primary tooth is higher than that of a permanent tooth due to calcified conditions, etc. Moreover, when oral hygiene is poor, secondary caries develop around the restorative material, and then the restorative material easily detaches from the primary tooth. Based on the above, even if better adhesion is a necessary factor, the selection of materials well-adapted to the oral condition of each child is the most important factor.
