The apical leakage also increases as the angle of the bevel increases, due to larger number of dentinal tubules and its permeability.17 It is easily detectable in radiographs as it is more radiopaque than gutta purcha and dentin.16 Ding et al reported that sodium phosphate dibasic solution did not interfere with the biocompatibility of the mineral trioxide aggregate.
Two previously calibrated examiners analyzed the images in a qualitative observation of the efficiency in cleaning and removing the amounts of filling materials through the existing measures of these remnants in root canal walls and dentinal tubules. This analysis was performed with a scoring system from 1 to 4, according to the percentage of root filling materials remnants per image area (Fig.
Pulp necrosis is one of the factors responsible for the progression of external inflammatory root resorption, because bacteria and their metabolic products can diffuse through the dentinal tubules, reach the root surface, and increase destruction in this area, thus making endodontic treatment necessary.
In this VDRR case, histological examination of the extracted tooth showed dentinal clefts/dilated dentinal tubules and these conditions agreed with the dental findings of VDRR.
The presence of a smear layer in root canals may be considered as a cause of failure because it harbors bacteria and tissue remnants (2) and also reduces the penetration of irrigants, medicaments, and sealers into the dentinal tubules (3, 4).
According to Brannstrom's theory (1966), the main strategy for the treatment of DH would consists of sealing the dentinal tubules, hence preventing fluid flow movement.
The residual tissues will disintegrate progressively, and blood components will infiltrate into the dentinal tubules, causing discoloration.
Enterococcus faecalis is the most frequently isolated bacteria with treatment failure after root canal treatment (8) that can penetrate to depths between 160 and 1000 [micro]m into the lateral dentinal tubules (9).
It has been reported that yeasts like Candida albicans (CA) have the ability to grow as mono-infections and invade dentinal tubules through pseudo-mycelia.
