Resumen
VEGA-YSLACHIN, Margarita; VELASQUEZ-HUAMAN, Zulema y GARCIA-RUPAYA, Carmen Rosa. Comparison of the penetration of three endodontic sealers into dentinal tubules with scanning electron microscopy. Rev. Estomatol. Herediana [online]. 2024, vol.34, n.2, pp.127-135. Epub 29-Jun-2024. ISSN 1019-4355. http://dx.doi.org/10.20453/reh.v34i2.5530.
Objective:
To compare in vitro, using a scanning electron microscope, the penetration of three endodontic sealers: made of epoxy resin (AH Plus®), of polydimethylsiloxane (Roekoseal®), and of calcium hydroxide (Apexit Plus®) into the dentinal tubules at 3 mm and 7 mm from the root apex, with the lateral compaction technique in uniradicular lower premolars.
Materials and methods:
In vitro study. Thirty-six teeth were prepared and divided into three groups of 12 teeth each. All the teeth were prepared and each group was obturated with three different endodontic sealers. Subsequently, the teeth were cut transversely at 3 mm and 7 mm from the root apex; then they were prepared to be taken to the scanning electron microscope to observe the penetration of the sealers in the dentinal tubules.
Results:
ANOVA test was used to compare the 3 groups and Student's t-test was used to evaluate the penetration of each of the sealers at 3 mm and 7 mm. Tukey's post hoc test was also performed to evaluate between sealer groups. When comparing the 3 groups of endodontic sealers, greater penetration was found with the Roekoseal® sealer at 3 mm with a statistically significant difference, ANOVA test (p = 0.04). When comparing each of the sealers at 3 mm and 7 mm, significant differences were only found (p = 0.04) in AH Plus®, showing better penetration at 7 mm with respect to 3 mm; and when the sealer groups were compared, both at 3 mm and 7 mm, no statistically significant differences were found.
Conclusions:
All three sealers evaluated in vitro penetrated in the dentinal tubules. At 3 mm, the Roekoseal® sealer outperformed the other two sealers; and at 7 mm, there was no significant difference between them.
