Failure of tooth eruption is more common in permanent teeth than in deciduous teeth.The most commonly affected teeth are deciduous mandibular second molars in deciduous dentition.In addition,accurate diagnosis of tooth eruption failure is challenging for clinicians,and its exact etiology remains unknown.The consensus on the management of tooth eruption failure in deciduous molars has not been reached.At present,observation,restoration,extraction,surgi-cal luxation,or orthodontic traction are the available treatment methods.Appropriate treatment options primarily rely on the type and severity of tooth eruption failure,the succeeding permanent teeth,and the accompanied complications.Thus,this article reviews the etiology,clinical manifestations,classification,and treatments of tooth eruption failure in deci-duous molars to provide some reference for related clinical diagnosis and treatments.
