目的了解砖茶型氟中毒对儿童骨骼发育的影响。方法考察西藏那曲县长期摄入砖茶的132名8~13岁儿童中的110名氟斑牙患者,进行全身骨关节物理检查和双手正位X线检查。结果在110名砖茶型氟斑牙患儿中没有任何明显的骨关节主观症状或客观体征,但96名儿童有明确的骨发育异常X线征象,其检出率为87%。X线主要表现为手部诸骨的骨纹理粗疏(95%),干骺端出现间歇性生长障碍线(65%)。随着年龄增长,这些征象有减少倾向。结论砖茶型氟中毒儿童手部诸骨出现骨发育异常的X线征,可以认为是儿童早期氟骨症的诊断依据,并认为早期预防是最佳控制砖茶型氟中毒的方案。
Objective To understand the effect of brick-tea fluorosis on skeletal development in children. Methods Totally 110 dental fluorosis patients from 132 children aged 8 ~ 13 years old who took brick tea in Naqu County, Tibet Autonomous Region were investigated for whole body physical examination of the joints and two-hand orthopedic X-ray examination. Results There were no obvious subjective symptoms or objective signs of osteoarthritis in 110 children with brick-tea-type dental fluorosis. However, 96 children had definite signs of abnormal X-ray of bone development with a detection rate of 87%. X-ray showed mainly the bone texture of the hand bone coarse (95%), metaphyseal intermittent growth disorder line (65%). As you grow older, these signs tend to decrease. Conclusion X-ray sign of bone dysplasia in the hands of children with brick-tea fluorosis can be regarded as the diagnosis basis of early fluorosis in children and early prevention is the best way to control brick-tea fluorosis.
