In view of achieveing the possible statistical association between two variables chi-squared test was used. Results: cured teeth predominated with 81% of the cases, followed by failed, sick (10.5%). In the failed cases and with functional retention, the main defficiency was apical filtration with 48%, within the latter imcomplete preparation and fillings of the principal radicular passage, 91.6%, particularly in short fillings, 53.9%.
