put together a T- chart of three unscientific ideas and misconceptions about diseases and provide scientific explanations in order to clear these misconceptions.

The three ideas not based on scientific evidence are:

Pregnancy causes your teeth to lose scale.

Lower fever with hot baths.

Brush your teeth with pure baking soda to avoid cavities.

Explanation:

During pregnancy, bone decalcifications occur if the mother has the beginning of malnutrition or advanced malnutrition, said this, decalcification occurs in long bones or other parts of the body since they are the sources with the highest calcium, calcium is never taken from the dental hydroxyapatite structure since this is hexagonal, more difficult to reabsorb and also the calcium concentration is lower compared to a tibia or other long bone. The loss of teeth occurs due to lack of hygiene and periodontitis associated with infectious factors due to the presence of bacterial plaque enhanced by the hormonal degree.

The following explanation is what I name in terms of fever, since it is lowered by immersing the person in warm water, where it cools slowly so that the external cold temperature takes the body heat and reduces the excess temperature generated by the hypothalamus, it is never good to bathe with hot water since in this way we increase the internal body temperature more because our body does not give heat to the environment, but takes more of it.

The ideal would also be to take an antipyretic such as paracetamol since it influences at the level of the CNS and works in the hypothalamus that is why it is a good antipyretic.

Finally, sodium bicarbonate is an abrasive, which wears down the adamantine surface of the teeth, generating micro-abrasions that then facilitate the retention of dental biofilm, causing it to decalcify the hydroxaxyapatite and form caries by acting as a micro-abrasion site. retention, then SALTS LIKE BICARBONATE SHOULD NOT BE USED TO ELIMINATE CARIES OR CURE THEM, for this it is necessary to go to the alodontologist and take a good habit of dental hygiene in a correct and personalized way.

over half of the people in the united states rely on groundwater for drinking water.

it's true
