Title: Análise de duas metodologias na aferição de infiltração por corante em apicoplastias com retrobturações
Issue Date: 2010
Abstract: Different methods have been used in studies on marginalinfiltration caused by staining dye with the purposeof evaluating the efficiency of dental materialsemployed in apicoplasties with retrograde root filling.Apicoplasty consists of flattening the root apex eliminatingthe need of root amputation, maintaining its correctshape. The objective of the present study was toevaluate the results of infiltration of rhodamine B 1%in an experimental group, comparing the dye depth penetrationwith the impregnation area in the same samplesthat underwent apicoplasties with retrograde rootfilling. The samples included 12 human upper canineteeth endodontically treated and retro-obturated usingMTA. For sample analysis, the Image Tool® software wasused to perform computerized morphometry. Resultsshowed a low standard deviation (4.79) regarding areameasurement, and high standard deviation (15.05) interms of measurement of the dye depth penetration. TheMann-Whitney test showed statistically significant differencesbetween the groups (p < 0.0001). The use of thedye stained area, instead of dye depth penetration, provedto be a better choice for measuring marginal infiltrationscores according to the methodological parametersused in the present study.
