Through an adaptation of Miller's experiment, where saliva was collected
from donors in a sterilized, closed glass container and a sugar-based
substrate (sucrose) was added. In addition, a human tooth extracted by
dental treatment was added to the set with the healthy dental crown +
signature of the informed consent form and the term of the patient's
donation by the patient. Phase I had a negative control (tooth + saliva
without sucrose supply) and the others were specifically opened after
01, 02, 03 and 04 months of incubation, and this served as a parameter
for the design of the next stage. In phase II, two saliva donors were
needed. In this phase, saliva donors with low levels of oral hygiene
were used. Tooth incubation (defined by phase I) was 02 and 03 months
for each donor. The influence exerted by the environment was able to
develop carious lesions in the dental elements. The record of the
experiment promotes the educational work on the risks of developing
dental caries, etiology and evolution, so as to allow the construction
of an explanatory booklet.
