| Resumo: | One of the main objectives of the endodontic treatment is to disinfect the root canal
through the use of instruments and auxiliary chemicals. As a result of this, the aim of
the present study is to verify and compare the degree of cleanliness of the root canal
walls after instrumentation and irrigation of the conduit with different irrigating
substances in the cervical, middle and apical thirds. For this, human pre-molars (n =
40) will have their crowns sectioned by standardizing the roots 15 mm long, and then
randomly divided into 5 (five) experimental groups according to the test substance (G1-
Positive Control: EDTA- Ethylene diamine tetracetic- Gel 17%, G2: Gel experimental 1,
G3: Gel experimental 2, G4: Gel experimental 3, G5: Natrosol). All roots will be
instrumented with the Waveone reciprocating system (Maillefer Dentsplay), the duct
being flooded with 2ml of the substances tested at each instrument change. At the end
of the instrumentation all the groups will be irrigated with 5ml of saline solution to
remove possible residues of the substances. Afterwards, the teeth will be cleaved,
analyzed in Scanning Electron Microscopy (SEM) and photomicrographs. The
photomicrographs will be analyzed and classified as to the amount of residual layer of
magma found in the walls of the root canal. The data obtained will be tabulated and
subjected to non-parametric Kruskal-Wallis statistical tests at a significance level of 1%
(a = 0.01). The results showed that there was no statistical difference in the level of
cleanliness between the groups, between each third of the groups. However, in an
analysis of each group, the G3 presented statistical variation in the cleaning of the
apical and cervical thirds. In that case the first cleaned less than the second. |
