摘要
众所周知,恒牙发育阶段摄入过多氟常导致氟斑牙,氟斑牙和氟骨症两者的发生率是否有联系,氟斑牙率在地方性氟中毒研究中有多大意义尚无较确切的研究。为此,我们研究了氟斑牙率在地方性氟中毒定量流行病学上的意义,现报告于后。方法与标准一、环境与社会调查:在居民饮水氟含量为0.2至25.0mg/L
In this paper,we describe therelation between the mottled ena-mel and osteofluorosis,urine fluo-ride and water fluoride respectively inten residential quarters where the w-ater fluoride range from 0.31—12.8mg/L in Kuitun River basin.The incid-ences of the mottled enamel amongthe children of 8—15 years oldwere increased with drinking w-ater fluoride.A positive correlationwas found between the incidence a-nd water fluoride(P<0.001).The relationship in water fluo-ride,defective enamel and endemicosteofluorosis were close each oth-er.The correlation coefficient betw-een the defective enamel and ende-mic osteofluorosis was 0.9663(P<0.001),and the curvilineal regres-sion equation was lg(Y+15)=0.01003X+1.205.Besides these,closepositive correlation was found bet-ween defective enamel and urine f-luoride or the output of fluoridefrom urination in unit time.Theincidence of defective enamel in 8-15 years old is a good index for e-pidemiological investigation of endemicfluorosis.
