摘　　要：龋病和牙外伤是儿童常见的口腔疾病,是导致乳牙牙体组织缺损甚至牙列缺损的主要原因。维护乳牙和乳牙列的完整性有利于儿童局部口腔健康,促进颅颌面健康发育、全身生长发育及心理健康。乳切牙的缺损可分为药物抑制龋坏治疗和修复治疗,后者是最主要的治疗方法,包括直接充填修复、全冠修复和桩核冠修复等。本文就乳切牙牙体缺损的各类修复治疗方式的背景、适应证、临床操作步骤及相关研究等方面进行阐述,为乳切牙缺损的修复提供参考。文献复习结果表明:直接充填修复法应用最为广泛,但技术敏感性较高,多只用于单面洞修复;全冠修复种类较多,各具优势,目前树脂透明成形冠套和全瓷冠应用最多,美观性能最佳;桩核冠修复存有争议,可吸收根管桩可能成为此类研究的热点。总体而言临床修复方式的选择并无精确的量表指南,需综合考虑患牙牙体组织的缺损程度、患儿的合作性、家长的满意度等多方面的因素进行选择。Dental caries and trauma are the most common oral diseases in children,which could result in defects of the teeth or detention.Maintenance of the primary dentition in a nonpathologic condition is important for oral health,cra⁃niofacial development,and the overall well⁃being of the children.In contemporary dentistry,primary anterior teeth de⁃fects are mainly treated with drugs,restorative treatments,or both.Restorative treatment is the most preferred method and includes direct restoration,full coronal restoration,post⁃and⁃core crowns,etc.This article reviews the available infor⁃mation regarding a variety of restorative treatments for primary incisor defects,including their backgrounds,clinical indi⁃cations,clinical pathways,and related studies.The literature review shows that intraconal direct restoration is widely used on single surfaces.There are many kinds of full coronal restorations,and each has its own advantages.Pediatric res⁃in⁃bonded strip crowns and zirconia crowns are the most popular and have excellent aesthetics.The use of post⁃and⁃core crowns for primary incisors is controversial.The absorbable post may be the next research hotspot.Therefore,treatment of severely destroyed primary incisors poses a challenge for pediatric dentists,as three important considerations must be kept in mind:children′s behavioral management,preservation of the tooth structure and parental satisfaction.
