propriedades físico-químicas da água potencialmente oxidativa e sua capacidade de instrumentação remoção da camada residual
Journal Title: RSBO - Year 2006, Vol 3, Issue 2
Abstract
The purpose of the study was to elaborate the potentially oxidative water (POW) and analyze some of the physico-chemical properties: pH density, superficial stress, contact angle, conductivity and REDOX potential; besides comparing its POW organic as well as non-organic matter removal capacity with hypochlorite sodium at 1% plus 17% EDTA. For the methodology the POW elaboration an electrolysis process was used and the physico-chemical properties were determined in 0, 1, 3, 5 and 7 days. For the removal capacity of teeth tartar evaluation, 30 extracted uniradicular premolars were used, divided in three groups: positive control (NaOCl at 1% + EDTA at 17%), negative control (distilled water) and experimental (POW). Afterwards, the samples were observed under electronic microscopy with 2500x magnifying at the middle thirds and apical, analyzing them with the Rome scale (amount of open dental tubes). For the statistical analysis the Chi-square and the Fisher Exact Proof was used. The results showed that the solution was constantly maintained at all times during the evaluation and there was found statistical difference between negative control and positive control and between negative control and the experimental group. With regards to the dental tartar removal it was found that there was no statistical difference between the control group and the experimental group (POW); reason why it is concluded that the POW has the capacity to remove dental tartar. Nevertheless, to be able to propose the use of the POW as an irrigator solution in Endodontics it is necessary to do further studies to evaluate its cytotoxicity and biocompability.
