目的 牙釉质脱矿是固定矫治常见的并发症.本研究比较了固定矫治中釉质脱矿与健康状态下龈上菌斑真菌组的差异,探索口腔真菌与正畸釉质脱矿的关系.方法 选取 54 名固定矫治患者,釉质脱矿组 31人,健康对照组 23 人.收集龈上菌斑,通过转录间隔子测序比较两组真菌组差异,使用RT-qPCR分析白色念珠菌的丰度变化.结果 两组真菌微生物多样性和优势物种丰度均存在显著差异.脱矿组真菌微生物多样性降低,念珠菌属及白色念珠菌在脱矿组中富集,且白色念珠菌在脱矿组中丰度较高(P<0.05).结论 青少年固定矫治脱矿状态下龈上菌斑真菌组与健康状态存在显著差异,白色念珠菌更易富集在脱矿菌斑中,可能与釉质脱矿的发生发展密切相关.
Objective White spot lesions(WSLs)have a high incidence in fixed orthodontic patients.This study aims at exploring the differences in supragingival dental fungal microbiome between health and WSLs state during fixed orthodontic treatment and explore the potential role of fungal microbiome in orthodontic WSLs.Methods 54 patients undergoing fixed orthodontic treatment were selected in this study,including 31 in the WSLs group and 23 in the healthy group.ITS sequencing was used to compare the differences in supragingival fungal microbiome between the two groups,and the absolute abundance of Candida albicans was quantitatively analyzed by RT-qPCR.Results There were significant differences in microbial diversity and abundance of dominant genera between WSLs and the control group.The community diversity of fungal microbiome decreased significantly in the WSLs group,and Candida as well as Candida albicans were significantly enriched in the WSLs group.In addition,the absolute abundance of Candida albicans in the WSLs group was significantly higher than that in the control group(P<0.05).Conclusions Our study elucidated that there are significant differences in the supragingival fungal microbiome between adolescent patients with or without WSLs.Candida albicans is more enriched in demineralized lesions,which may be closely related to the occurrence and development of WSLs in fixed orthodontics.
