ホメーロス風讃歌
An ancient Sumerian text describes a "tooth worm" as the cause of dental caries. Evidence of this belief has also been found in ancient India, Egypt, Japan, and China. The legend of the worm is also found in the "Homeric Hymns", and as late as the 14th century AD the surgeon Guy de Chauliac still promoted the belief that worms cause tooth decay.
