In the higher doses used to treat osteoporosis , plain sodium fluoride can cause pain in the legs and incomplete stress fractures when the doses are too high; it also irritates the stomach, sometimes so severely as to cause ulcers. Slow-release and enteric-coated versions of sodium fluoride do not have gastric side effects in any significant way, and have milder and less frequent complications in the bones. [30] In the lower doses used for water fluoridation, the only clear adverse effect is dental fluorosis , which can alter the appearance of children's teeth during tooth development ; this is mostly mild and is unlikely to represent any real effect on aesthetic appearance or on public health. [31] A chronic fluoride ingestion of 1 ppm of fluoride in drinking water can cause mottling of the teeth (fluorosis) and an exposure of ppm will produce mottling in 30–50 % of patients. [26]

Results of analysis of the performance of the two protocols by assessing the accuracy of the CT number, noise, low contrast resolution and spatial resolution showed that high-dose protocol has better performance than low-dose protocol. Image with high-dose protocol has an average GM conspicuity of and CNR , while the image with a low dose of and at CNR. Comparison of gray scale image of the protocol through the image histogram comparison homogeneous phantom and patient image shows that the image of a low-dose protocol has variation of intensity gray value that is wider than high-dose protocol.
