摘要： 目的 了解苏州市2015年中小学生的恒牙龋患情况,探索防治重点,为更好地防龋提供科学依据。方法 采用描述流行病学方法,以龋失补率、龋患率、龋均等为指标,描述不同年龄、不同性别、不同生源、不同学校性质学生的恒牙龋患情况。结果 2015年苏州市中小学生总恒牙龋患率为8.4%,总恒牙龋均为0.18。随着年龄增长,恒牙龋患率和恒龋均呈上升趋势(P<0.001),低年龄组学生的恒龋患率增速快。女生、城市学校、公办学校均有更高的恒牙龋患率和恒龋均(P<0.01),男生、乡村学校和民工子弟学校的恒龋失、补情况更严重(P<0.001)。结论 口腔卫生保健应从低龄学生抓起,应加强乡村学校和民工子弟学校学生的口腔健康知识宣传。
