| Popis: |
In this study 31 clinical cases were compared and a statistical analysis was realized based on variations of apical resistance points quantified in ohms. For each case the pulpal pathology and the type of irrigants used were systematically reported in a table. The electronic endodontic measures which are radiographically controlled, result from a numeric conversion of electrical signals. This numerization facilitates the memorization of the resistances measured at the sulcus and during endodontic root canal preparation. Analysis of the means and the standard deviations emphasizes the lack of reliability of precalibrated electronic devices or individually standardized instruments, used to measure the working length. This study also shows an ohms drop at the apical constriction, depending on the electrochemical pathological conditions of the canal or of the periapical area. |
