Abstract
Endodontology deals with teaching, treatment and prevention of diseases of the
endodont (pulp-dentin complex) and periapical tissues. The aim is to achieve
long-term preservation of the stomatognathic system, contributed to by sufficient
root canal fillings. More precisely, sufficient root canal filling depends on several
factors. One is sufficient sealer penetration into the freely exposed dentinal
tubules after uniform canal preparation. In 2016, a new tricalcium-based sealer,
BioRoot RCS, from Septodont was introduced to the dental trade. On the one
hand, the biocompatible sealant and, on the other hand, the alkaline pH value of
>11 generated by the release of calcium ions should enable sufficient completion
of the root canal filling.
Aim
The purpose of this study was to demonstrate the penetration depth of BioRoot
RCS in different obturation methods and always in comparison to a reference
group consisting of AH Plus.
6.2 Materials and Methods
A total of 60 human single-rooted teeth were divided into four study groups. All
teeth were cleaned and prepared with the F360 filing system. Root canal irrigation
was performed using a standardized irrigation protocol consisting of NaOCl 5.25
% and EDTA 15 %. The four study groups included the reference group (AH Plus)
LC (lateral condensation) filled, the BioRoot RCS LC filled group, an SC filled
group with BioRoot RCS, and a group filled with Biodentine and BioRoot. The
fluorescent dyes rhodamine B isotiocyanate and fluorescein sodium were added
tot he sealers prior to use. After four weeks of curing of the sealers in the root
canals, the samples were sawed and examined under the confocal laser
scanning microscope.49
Results
The reference group with AH Plus showed significantly less penetration depths
of 79 µm compared to BioRoot RCS with significantly increased 159 – 164 µm
penetration depth in the apical and middle sextions oft he root canals. In the
middle root region, the study groups differentiated, with BioRoot RCS LC
penetrating significantly deeper at 329 µm to AH Plus LC 230 µm in a direct
comparison of the filling technique. The coronal penetration of LC with BioRoot
RCS 237 µm was inferior to LC with AH Plus by 295 µm. Nevertheless, the SC
technique achieved similar results to LC with AH Plus at 293 µm – 295 µm. The
median values of group 4 to be investigated with Biodentine was always on par
with the LC technique with AH Plus. (see chart 2)
Conclusion
Within the limits of this in vitro study, it can be concluded that BioRoot RCS
penetrates deeper into dentinal tubules than the comparison groups with AH Plus.
BioRoot RCS penetrates apically deeper than the reference group in both filling
groups. In the medial region, lateral condensation has higher penetration depths
than AH Plus. Coronally, however, all study groups show approximately similar
values.
