新疆农三师伽师总场改水降氟后12~15岁少年氟斑牙的病情调查及相关因素分析

Condition Survey and Analysis of Relevant Factors on 12~15 Years Old Youths with Dental Fluorosis after Water-improving and Defluoridation in Jiashi General Farm of the Third Agricultural Division of Xinjiang

目的:调查新疆农三师伽师总场改水降氟后12~15岁少年氟斑牙的患病特点,分析其相关因素,了解改水降氟对伽师总场地氟病的效果。方法:2018年对伽师总场下属的12个连队进行水氟检测,包括7个水氟合格连队和5个水氟未合格连队。检测所有连队12~15岁少年的氟斑牙及尿氟含量,对氟斑牙的相关因素进行Logistic回归分析。结果:共调查12~15岁少年1 148名,氟斑牙检出率为71.5%,氟斑牙缺损检出率为28.4%。水氟合格连队的氟斑牙检出率(50.7%vs 95.2%)、中重度斑检出率(3.1% vs 24.0%)、氟斑牙缺损检出率(0.0% vs 28.4%)均明显低于水氟未合格连队(P<0.05)。12~13岁少年的氟斑牙检出率(65.4% vs 76.9%)、中重度氟斑牙检出率(8.6%vs 16.7%)、氟斑牙缺损检出率(11.2%vs 15.2%)均明显低于14~15岁少年(P<0.05)。男性少年的中重度氟斑牙检出率(9.2% vs 16.8%)、氟斑牙缺损检出率(10.6% vs 16.3%)均明显低于女性少年(P<0.05)。水氟合格连队的尿氟含量[(1.5±0.4)mg/L vs (5.1±2.9)mg/L]、超标率(71.0% vs 95.5%)均明显低于水氟未合格连队(P<0.05),12~13岁少年的尿氟含量[(3.2±1.5)mg/L vs (4.4±2.6)mg/L]、超标率(79.5% vs 85.1%)均明显低于14~15岁少年(P<0.05)。氟斑牙检出率与尿氟含量呈明显正相关(r=0.615,P=0.000),尿氟含量随着氟斑牙严重程度的加重而不断增高,差异具有统计学意义(P<0.05)。水氟未合格连队的氟斑牙发生风险是水氟合格连队的15.462倍,尿氟超标少年的氟斑牙发生风险是尿氟未超标少年的2.584倍,14~15岁少年的氟斑牙发生风险是12~13岁少年的2.065倍,女性少年的氟斑牙(中重度)发生风险是男性少年的1.998倍。结论:改水降氟能够有效控制伽师总场12~15岁少年氟斑牙的流行,水氟、年龄、性别是氟斑牙发生的相关因素。

Objective To investigate the prevalence characteristics of dental fluorosis on 12~15 years old youths with dental fluorosis after water-improving and defluoridation in Jiashi general farm of the third agricultural division of Xinjiang,analyze the relevant factors,and understand the effect of fluorosis on dental fluorosis after water-improving and defluoridation in Jiashi general farm.Methods In 2018,the water fluoride was detected in 12 companies affiliated to Jiashi general farm,including 7 companies with qualified water fluoride and 5 companies with unqualified water fluoride.Dental fluorosis and urine fluorosis content of 12~15 years old youths were detected in all companies,and the relevant factors of dental fluorosis was analyzed with Logistic regression analysis.Results A total of 1148 youths aged 12~15 years who were investigated.The detection rate of dental fluorosis was 71.5%and the detecti on rate of dental fluorosis defect was 28.4%.The detection rate of dental fluorosis(50.7%vs 95.2%),detection rate of moderate-severe dental fluorosis(3.1%vs 24.0%),detection rate of dental fluorosis defect(0.0%vs 28.4%)of companies with qualified water fluoride was significantly lower than that of companies with unqualified water fluoride(P<0.05).The detection rate of dental fluorosis(65.4%vs 76.9%),detection rate of moderate-severe dental fluorosis(8.6%vs 16.7%),detection rate of dental fluorosis defect(11.2%vs 15.2%)of 1213 years old youths were significantly lower than that of 14~15 years old youths(P<0.05).The detection rate of moderate-severe dental fluorosis(9.2%vs 16.8%),detection rate of dental fluorosis defect(10.6%vs 16.3%)of male youths were significantly lower than that of female youths(P<0.05).The urine fluorosis content[(1.5±0.4)mg/L vs(5.1±2.9)mg/L],over standard rate(71.0%vs 95.5%)of companies with qualified water fluoride was significantly lower than that of companies unqualified water fluoride(P<0.05).The urine fluorosis content[(3.2±1.5)mg/L vs(4.4±2.6)mg/L],over standard rate(71.0%vs 95.5%)of 12~13 years old youths were significantly lower than that of 14~15 years old youths(P<0.05).The detection rate of dental fluorosis was significantly positive correlation with urine fluorosis content(r=0.615,P=0.000).Urine fluoride content was increased with the exacerabation of dental fluorosis severity,and the difference was statistically significant(P<0.05).The risk of dental fluorosis of companies with unqualified water fluoride were 15.462 times higher than that of companies with qualified water fluoride.The risk of dental fluorosis with excessive urine fluorosis was 2.584 times higher than that of notexcessive urine fluorosis.The risk of dental fluorosis of 14~15 years old youths were 2.065 times higher than that of 12~13 years old youths.The risk of dental fluorosis(moderate-severe)of male youths were 1.998 times higher than that of female youths.Conclusion Water-improving and defluoridation could effectively control the prevalence of dental fluorosis on 12~15 years old youths in Jiashi general farm.Water fluoride,age and gender was the relevant factors of dental fluorosis.
