Abstract EN

Background and Aim: The quality of root canal filling is considered the key of successful endodontic treatment because one of the goals of root canal obturation is to obtain three-dimensional and complete sealing.

Therefore, The aim of this in vivo study was to evaluate the quality of root canal filling of whitecolored mineral trioxide aggregate (WMTA) and gray-colored portland cement (GPC) using radiographs.

Materials and Methods: The sample of study consisted of 120 single-canal, permanent human vital teeth.

The root canals were prepared using Crown-Down technique.

The sample was divided into 5 main groups according to the root canal filling material used: [Group1: (WMTA) alone, Group2: (GPC) alone].

the two materials were applied on 40 vital teeth, prepared to extraction for orthodontic purposes.

They were distributed into two equal groups of 20 teeth each.

[Group3: (Gutta-percha points + WMTA), Group4: (Gutta-percha points + GPC), Group5: (Gutta-percha points + AH26)].

these materials were applied on 80 vital teeth, indicated to endodontic treatment.

They were distributed into three groups: group 3, 4 consisted of 30 teeth, and group 5 consisted of 20 teeth.

The quality of root canal filling was evaluated using radiograghs.

Data were subjected to Kruskal-Wallis statistical test with (P-value ≥ 0.05) as the level of significance.

Results: The results showed that there were no statistically significant differences in the quality of root canal filling among the materials of five groups.

Conclusions: (WMTA) and (GPC) can be used in root canal filling, alone or with gutta-percha points.
