Abstract
Early childhood caries which mainly affect maxillary anterior area, defined as 'the presence of 1 or more decayed, missing, or filled tooth surfaces in any primary tooth in a child 71 months of age or younger'. Extraction of teeth when early childhood caries affected in maxillary primary incisors often develops progressively, result in severe destruction of crowns, acute or chronic pulpitis, and periapical abscess formation. Maxillary primary incisors are need to preserve as possible, because the early loss of maxillary primary incisors may lead to various functional, esthetical, and psychological problems. It is necessary to the availability of an easy to perform technique capable of providing efficient, durable, functional, and esthetic restorative methods. Polyethylene fiber-reinforced post can be used in strengthen of composite resins that is esthetic and good physical and mechanical properties. $Ribbond^{(R)}$ 수식 이미지 is made from an polyethylene fiber, has numerous usages, its surface is treated to enhance adhesion to resins, ease of manipulation, relatively cost effective. We report this case, had restored of maxillary primary incisors with severe coronal destruction due to affecting severe early childhood caries, using polyethylene fiber-reinforced posts, composite resin cores, and celluloid crowns. We could obtain good result of treatment.
Key Words: Polyethylene fiber-reinforced post, Severe early childhood caries, Composite resin core, Celluloid crown
