In three different areas of Finland, fluoride in bone and its effect on the histomorphometry of trabecular bone was studied. Bone samples were taken from cadavers from a low-fluoride area (fluoride concentration under 0.3 ppm), an area with fluoridated drinking water (1.0-1.2 ppm) and a high-fluoride area (over 1.5 ppm). The fluoride content in trabecular bone was greatly increased in the high-fluoride area, and it was also higher in the fluoridated-water area than in the low-fluoride area. Histomorphometric bone changes were markedly increased when the fluoride content in water exceeded 1.5 ppm.
在芬兰的三个不同地区，研究了骨骼中的氟化物及其对松质骨组织形态计量学的影响。骨样本取自一个低氟地区（氟化物浓度低于0.3 ppm）、一个饮用氟化水地区（1.0 - 1.2 ppm）和一个高氟地区（超过1.5 ppm）的尸体。高氟地区松质骨中的氟化物含量大幅增加，且饮用氟化水地区的氟化物含量也高于低氟地区。当水中氟化物含量超过1.5 ppm时，骨组织形态计量学变化显著增加。
