Abstract:

In the treatment of the channels of unfinished permanent teeth with necrotic pulp root end, providing sufficient apical blocks is a clinical condition that causes difficulties in dental medicine. The fluidity of the channel filling material used is of importance for success. The aim of this study is to compare the leakage rates of BioAgregat [BioAggregate, Verio Dental Co. Ltd., Vancouver, Canada BA ] applied in different thicknesses in the single session apexification model using the liquid filtration method. In our study we used 24 single-root little female tracks drawn for orthodontic purposes. After the teeth were cut from the mine-sement combination, the root length was cut 3-4mm from the apical root end so that it would be 12mm. To simulate the clinical condition, the apical and curonal 1/3 parts of the roots were expanded with the 2-6 Gates glidden freezes. The teeth were randomly divided into 3 groups according to the BA thickness placed in the channel: Group 1:2mm, Group 2:4mm, and Group 3:12mm full channel length. After the teeth were kept 4 days at 37°C in order to the hardening reaction of BA, the empty parts of the channels were filled in the first 2 groups with rubber and the quantities of discharge were measured by the liquid transport method in all groups. The analysis of the data used the Kruskal Wallis H test. While there is no statistically meaningful difference between Group 1 and 2, p>0,05 found less in statistically meaningful levels of discharge compared to Group 3 of all BA-filled channels.
