REAL APARICIO, María Constanza. Comparison of the effectiveness of materials used as retrograde obturators in apical dental surgeries. Rev. Nac. (Itauguá) [online]. 2019, vol.11, n.2, pp.64-101. ISSN 2072-8174.  https://doi.org/10.18004/rdn2019.0011.02.064-101.

Introduction:

periradicular lesions appear only when the root canals are exposed to the oral microbiota. These root canals house several bacterial species and their toxins that reach the periradicular tissues and the formation of lesions begins

Objective:

to evaluate the effectiveness of the materials used as retrograde obturators in apical surgeries according to microfiltration capacity and marginal adaptation in permanent teeth.

Methodology:

a bibliographic review of electronic databases of the last 10 years was carried out. Non-original articles were excluded, which only measured the effectiveness of a material or that compared two brands or types of the same material.

Results:

the largest number of articles were from 2014. The MTA was the most studied material. The amalgam is studied until 2015 and in the same year the Biodentine research disappears. Most articles evaluated microfiltration to measure effectiveness. The material that was considered effective in the highest percentage was the MTA with 27% in microfiltration studies and 15% adaptation. Biodentine is next with 15% of microfiltration studies and 6% of marginal adaptation. It can be concluded that MTA is still the most effective material when used in retrograde seals, followed by Biodentine.

Conclusions:

based on the results of the researchers, the newly manufactured material, Biodentine, could be considered as effectively as the MTA.
