摘要: [摘要] 目的 调查分析舟山市小学生第一恒磨牙患龋情况,为龋病防治工作提供参考。方法 对舟山市市属9所小学共1035名小学二年级学生第一恒磨牙萌出情况、窝沟情况、龋坏状况进行分类记录、检查,结果汇总分析。结果 1035名小学二年级学生中,第一恒磨牙一颗未萌出人数为89人,萌出率为91.4%,第一恒磨牙总萌出牙数为3345颗。495人第一恒磨牙一颗或多颗龋坏,患龋率47.8%。结论 舟山市二年级学生第一恒磨牙患龋率明显高于全国平均水平及周边城市,可能与地理位置偏僻,交通不便,居民经济水平和文化认知水平都较为有限有关,应加大力度进行口腔卫生知识宣传工作,增强广大家长与儿童的口腔保健意识,才能最大限度地控制龋齿的发病率,减少龋齿对儿童远期的口腔、身心健康造成的影响。

Abstract: Abstract: Objective To investigate the first permanent molar status of primary-school students in Zhoushan City, as a reference for dental caries prevention and treatment. Methods The eruption out, nest ditch, and caries status of first permanent molars of 1035 second-grade students were inspected, recorded, classified and analyzed. Results Among the 1035 students inspected, 3345 first permanent molars had erupted, but 89 had no erupted first permanent molar with calculated eruption rate 91.4%. And 495 students were found to have one molar or several molars caries with calculated caries rate 47.8%. Conclusion The first-permanent-molar caries rate of Zhoushan City is significantly higher than the national average level, which is probably connected with geographical remoteness, traffic inconvenience, and local economical/cultural development level. In order to reduce the dental caries incidence and the effect of dental caries on children’s oral and mental health, it is very important to popularize oral health knowledge to local residents and improve their awareness of oral health.
