The only generally accepted adverse effect of fluoride at levels used for water fluoridation is dental fluorosis, which can alter the appearance of children's teeth during tooth development; this is mostly mild and usually only an aesthetic concern. Compared to unfluoridated water, fluoridation to 1 mg/L is estimated to cause fluorosis in one ...
The Gila monster lacks strong musculature in glands above the eyes; instead, in Heloderma, the venom is propelled from the gland via a tubing to the base of the lower teeth and then by capillary forces into two grooves of the tooth and then chewed into the victim. [3] [29] The teeth are tightly anchored to the jaw . Broken and regular ...
They have upper and lower teeth that fuse into a shape of a parrot's beak; they use this beak to eat molluscs and sea urchins. [ 4 ] [ 8 ] [ 9 ] Some species are poisonous, having tetrodotoxin in their internal organs, such as the ovaries and liver.
No teeth brushing. No washing dishes (since hot or warm water could release the toxins). Pets should not drink the water either. Solomon said she's not sure how watering plants outside would be ...
The KLK1 in solenodon venom is very similar to serine protease found in venomous snakes like vipers, and has evolved in parallel in both lineages from an ancient toxin precursor. [17] Solenodons create venom in enlarged submaxillary glands, and only inject venom through their bottom set of teeth.
Snake venom is a highly toxic saliva [1] containing zootoxins that facilitates in the immobilization and digestion of prey. This also provides defense against threats. Snake venom is usually injected by unique fangs during a bite, though some species are also able to spit venom. [2]
Fears about fluoride were likely exacerbated by the reputation of fluoride compounds as insect poisons and by early literature which tended to use terms such as "toxic" and "low grade chronic fluoride poisoning" to describe mottling from consumption of 6 mg/L of fluoride prior to tooth eruption, a level of consumption not expected to occur ...
This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be used.Supporters claim that it is safe, effective and long-lasting, while critics argue that amalgam is unsafe because it may cause mercury poisoning and other toxicity.
