Oats are more tolerant to extreme conditions than some of their grassy relatives, like wheat, and it is probable that they began to be cultivated in Europe for that reason. This grain continues to be farmed all over the world in areas that are not suited to more finicky grains.
Dental chart (tooth numbering) Teeth are numbered in order to identify them with ease. However there are two common systems of numbering teeth that can confuse unless you know which one you are using. America uses the Universal numbering system and numbers teeth like this:
Teeth 1 and 2 are the incisors. 3 is the canine (cuspid). 4 and 5 are bicuspids. 6, 7, and 8 are molars. The 6 is your 6 year molar, the 7 your 12 year molar, and the 8 is your wisdom tooth. Identifying a tooth is easy. All tooth numbers are a combination of the quadrant and then the tooth number. For example, tooth number 14 would be the upper right bicuspid. Tooth 21 is the first incisor on the top left.
