好的牙·讯|5月13日,美国食品药品监督管理局(FDA)宣布启动对儿童可摄入氟化物处方药品的撤市程序。该类产品主要为高浓度氟化物口服药剂,供婴幼儿吞咽使用,但从未通过FDA审批。

FDA称,研究表明摄入氟化物可能改变儿童肠道微生物群,而肠道菌群在幼年发育阶段尤为关键。 另有研究指出氟化物与甲状腺疾病、体重增加及潜在智商下降存在关联。FDA专员Marty Makary强调,预防龋齿应通过控制糖分摄入和保持口腔卫生实现,而非干预儿童肠道健康。

根据FDA的声明,该机构已设定目标,计划于2025年10月31日前完成对这些产品的安全审查及公众意见征集。

FDA的这一决定与当前美国多个州宣布停止饮用水加氟的趋势相一致。美国卫生与公众服务部(HHS)部长Robert F. Kennedy, Jr.称此举符合“让美国重获健康”的目标,并提及欧洲等多国早已停止饮用水加氟。

美国牙科卫生师协会(ADHA)主席Erin Haley-Hitz在同日发表声明,表达对FDA行动的关切。声明指出,低剂量氟化物(如浓度低于2毫克/升的氟化钠)尚无证据显示会影响人体肠道微生物群,且处方氟化物的使用需基于科学评估与监护人规范操作。

ADHA警告称,当前犹他州等地区正逐步取消社区饮水加氟措施,可能导致弱势群体及农村居民口腔健康进一步恶化。

ADHA强调,尽管控制糖分和口腔清洁是基础,氟化物与定期牙科检查仍是预防龋齿的核心手段,尤其对无法获得常规牙科服务的人群至关重要。协会呼吁政策制定者重视决策对公众口腔健康的影响,特别是弱势群体可能面临的加剧风险。
