| Research Abstract |
The effects of four kinds of daily meals on the in vitro calcification were studied using the pH drop method. Boiled rice increased the calcification, while toasted bread decreased it. A few dishes and food ingredients from meal 1-3 (e.g.potato) and Western-type meal 4 (e.g.butter) increased the calcification. However, since saliva in oral cavity inhibits their promoting effect, it is suggested that our daily meals may be inhibitory on the dental calculus formation.
