据日本《每日新闻》报道，日本科学家将在京都大学医学部附属医院开展世界上首个“牙齿再生药物”的临床试验。

Japanese scientists are set to kick off the world's first clinical trials of "tooth regrowth medicine" at the Kyoto University Hospital, The Mainichi reports.

来自日本初创公司Toregem Biopharma的研究人员计划招募一批从出生起就缺少部分或全部牙齿（先天缺牙症）的患者参加这次试验。

Researchers from the Japanese startup Toregem Biopharma are planning to enroll patients who were born missing some or all of their teeth from birth, a condition called congenital anodontia, for the trials.

患者将接受一种抗体治疗，这种治疗可以阻断一种名为USAG-1的蛋白质，科学家认为这种蛋白质阻止了大多数人的牙蕾发育成乳牙或恒牙。

The patients will receive an antibody treatment that deactivates a protein called USAG-1, believed to stop "tooth buds," which most people have, from developing into either baby or permanent teeth.

患有先天缺牙症的人通常选择种植牙或假牙。然而，正如《日经亚洲》援引Toregem公司共同创始人高桥克的声明所提到的，治疗可能将为他们提供“第三种选择”。

People with the condition conventionally resort to getting implants or dentures. However, Toregem's treatment could provide them with a "third option," as co-founder Katsu Takahashi explained in a statement, as quoted by Nikkei Asia.

研究团队希望不仅能治疗那些从出生起就无法长出牙齿的人，最终还能治疗那些因蛀牙而缺失牙齿的人。
