fluorosis n.【醫學】(慢性)氟中毒。

fluorspar

Methods : the scanning electron microscopy ( sem ) observations were made on 10 fluorosed teeth extracted from people of 30 - 40 years old for periodontitis reason from tanggu area , tianjing province ( water - drinking endemic fluorosis area ) , and from xianfeng county , hubei province ( coal - burning endemic fluorosis area ) respectively , and the observations were compared with those of 12 sound teeth extracted for orthodontic reason as control 方法:從燃煤污染型氟中毒病區湖北省恩施州咸豐縣和飲水型氟中毒病區天津市塘沽區分別收集30 - 40歲因牙周炎拔除的氟斑牙,各選10顆,對照牙為我院外科門診拔除的12顆完好正畸牙。

The discriminant functions mentioned above , except for the third one with a too small sample size , can be used in early discrimination of endemic fluorosis caused by exposure to coal burning , or in evaluation for the effectiveness of pharmaceutical therapy , with a power of 95 % 除第三類可能因樣本數太少判別效果稍差外,其他方程式有95 %的把握,可在地氟病區實際用于燃煤型地氟病早期判別、或作為藥物療效考核方法。

In humans excessive intake ( for adults , over 4 milligrams per day ) over many years can lead to skeletal fluorosis , a well - defined skeletal disorder , and in some plant species , fluoride is more toxic than ozone , sulfur dioxide , or pesticides 人類過量的攝入(成人每天超過4毫克)多年以后會導致骨骼氟中毒,一種容易識別的骨骼混亂(病癥) ,而且在某些植物中,氟化物的毒性要比臭氧、二氧化硫或者殺蟲劑都大。

Fluoride , for example , is an important component in bone and tooth structure . . too low a level of fluoride increases the incidence of dental caries , but an elevated level of fluoride causes mottling of the teeth as well as skeletal fluorosis 例如,氟化物是骨骼及牙結構的重要成分攝取氟化物不足會增加患蛀牙的機會,但攝取過量的氟化物卻會導致牙產生斑點,甚至引致骨骼氟中毒。

Methods one thousand six hundred and sixteen children in school under 16 years old that were sampled in cluster sampling were examined with dental fluorosis , x - ray in the type of burning coal pollution fluorosis areas of zhijin county guizhou province 方法按照整群隨機抽樣方法從貴州省織金縣隨機選擇16歲以下的在校學生1616人,進行氟斑牙和x線檢查。

Conclusion it may play an important role in the early prophylaxis and control measures studying the molecular mechanism of endemic fluorosis skeletal fluorosis especially in children 結論深入研究氟骨癥的分子發病機制,尤其是小兒氟骨癥的分子發病機制,對于制定氟骨癥的早期預防和控制措施具有重要的意義。

Objective to explore the prevalence satate of children in burning coal endemic fluorosis in zhijin county of guizhou province , provide the scientific basis for the prevention of skeletal fluorosis 摘要目的了解織金縣燃煤型氟病區兒童氟骨癥的患病情況,為該病的早期預防提供科學的依據。

Objective : to describe and compare the structure characteristics of enamel in human severely fluorotic teeth from water - drinking endemic fluorosis area and coal - burning endemic fluorosis area 摘要目的:描述并比較燃煤污染型和飲水型氟中毒地區重度氟斑牙釉質結構特點。

Results total prevalence rate of dental fluorosis was 96 . 42 % , prevalence rate of skeletal fluorosis was 7 . 49 % , constrictive skeletal fluorosis was main type in zhijin county guizhou province 結果氟斑牙總患病率為96 . 42 % ,氟骨癥患病率為7 . 49 % ,氟骨癥以硬化型為主。

Methods : 24 patients whose teeth exhibiting severe dental fluorosis and who need orthodontics were chosen , and there were all 444 teeth that orthodontic brackets should be bonded to 方法選取24例重度氟斑牙需要進行正畸的患者,共444顆需要粘結托槽的牙齒。

Objective to compare the advantage and defect of two decompression techniques using bone knife or not for treatment of thoracic spinal stenosis of skeletal fluorosis 摘要目的比較氟骨癥性胸椎管狹窄癥后路減壓手術中,應用骨刀和非骨刀兩種減壓方式。

Conclusion prevalence states of dental fluorosis and skeletal fluorosis are still serious , more effectual preventive and control measure shall be used 結論織金縣氟斑牙和氟骨癥患病情況依然嚴重,宜采取更加有效的措施加以控制。

Fluorosis is more common than arsenic poisoning because high - fluorine coal is combined with high - fluorine clay to make briquettes 氟中毒的病例比砷中毒更常見,因為含氟量高的煤與含氟量高的黏土混合,再制成煤餅、煤磚。
