摘　　要：根据世界卫生组织界定,青少年所涵盖的年龄是10~19岁[1]。青少年时期是人类生命发展的一个独特阶段,是生理和心理发生迅猛成长的关键时期。当前,世界上青少年的数量总计高达12亿,占全球总人口的六分之一[1],因此,青少年的口腔健康受到了愈发广泛的关注。青少年口腔情况复杂,且处于发育阶段。恒牙作为继乳牙脱落后的第二副牙列,一般在牙根形成2/3左右时开始萌出,但此时恒牙牙根尚未发育完成,这些虽已萌出,但未达到[牙合]平面的恒牙被称为年轻恒牙[2]。根尖部完全形成后的被动萌出导致恒牙在整个青少年时期持续存在临床冠长度的增加[3]。故而,青少年恒牙包括牙根未发育完成的年轻恒牙与牙根发育完成但龈缘位置仍未稳定的恒牙。Adolescence is defined as a population ranging from ten to nineteen years old.Permanent teeth in adolescents are of critical significance as they are actively involved in mastication,contribute to aesthetic appearance,play a role in pronunciation,and are integral to the growth and development of the stomatognathic system.Specifically,permanent teeth in adolescents comprise those with incomplete root development and those with complete root development but unstable gingival margin positions.However,the prevalence of permanent tooth defects among adolescents remains high,primarily due to their insufficient awareness of oral health care and poor compliance with preventive measures.Therefore,it is very important to emphasize the necessity for timely and appropriate restoration of permanent tooth defects in adolescents.Given the distinct physiological characteristics of adolescent permanent teeth compared with mature permanent teeth,interim restoration approaches are required.The field of adolescent permanent tooth restoration is an interdisciplinary area,involving both prosthodontics and pediatric dentistry.Currently,a comprehensive and standardized principle for the selection of restoration indications is lacking,which poses challenges for clinicians in making optimal treatment decisions.Therefore,this article aims to comprehensively summarize the clinical dilemmas associated with the restoration of adolescent permanent teeth,and propose a set of principles for the selection of restoration methods and materials,aiming to offer practical clinical guidelines for dentists when dealing with permanent tooth defects in adolescent patients.In particular,because of the different restoration dilemmas of anterior and posterior permanent teeth,a variety of interim restoration methods,their applicable conditions,advantages,and disadvantages are introduced respectively.Additionally,it provides an in-depth discussion of different interim restoration materials,including direct restoration materials like light-cured composite resin
