“…This approach allows accessing the level of clinical significance of the results provided by the laboratory models. With a similar model, Susini et al (16) were unable to establish a positive correlation between the dye leakage model and the in vivo presence of periapical radiolucency. Nevertheless, using methylene blue in a dye extraction model was successfully correlated to the quality of the root canal filling.…”

“…These models have been criticized for many factors mainly related to preclusion of direct clinical applicability of results. [23][24][25] Several authors also observed divergent results when comparing different types of leakage tests. Barthel et al 26 applied the dye leakage test after mine leakage.…”

Lack of correlation between obturation limits and apical leakage

The aim of this paper was to evaluate a possible correlation between obturation limits and leakage. Thirty-six extracted human mandibular incisors were used, characterized by straight and single canals, non-anatomical complexities, absence of previous endodontic treatment, complete root formation and patent foramen. For standardization of the specimens for the leakage analysis, foraminal instrumentation was performed up to a Flexofile #25 (Dentsply-Maillefer, Ballaigues, Switzerland). All specimens were instrumented and filled following the same protocol, and the obturation limits were measured using Axiovision 4.5 Software (Carl Zeiss Vision, Hallbergmoos, Germany). The specimens were then separated into three groups (n = 12) according to the following variables: Group I -obturation limits ranging from 0 mm to 0.76 mm of the main apical foramen. Group II -obturation limits ranging from 0.77 mm to 0.98 mm of the main apical foramen. Group III -obturation limits ranging from 0.99 mm to 1.68 mm of the main apical foramen. Apical leakage was quantified by fluid filtration. The analyses were confronted using Pearson's test (p > 0.05). Groups I, II and III showed Pearson correlation values (r 2 ) of −0.152, −0.186 and 0.058, respectively. No correlation was found between the obturation limits and apical leakage.

“…The primary disadvantage is debonding, which is considered a repairable complication. 2,[4][5][6][7][8] In 2005, Mannocci et al 9 presented a study that proved that restorations with fiber posts and composites were more effective than amalgam in preventing root fractures but less effective in preventing secondary caries. For prevention of secondary caries, the extent of microleakage should be taken into consideration while placing adhesively luted fiber posts.…”

Aim: To review the literature on the sealing ability of esthetic post systems with different cementation techniques.Background: An important factor for successful root canal treatment is the development of a coronal seal to the treated root canal system. Review result:The current literature describes promising results using fiber posts with a dual-cure, self-etch resin cement system. However, none of the published results describe a post system or cementation technique that achieved a homogeneous and tight coronal seal. Conclusion:Fiber post systems appear to be favorable alternatives to metallic or ceramic post systems. Furthermore, dual-cure, self-etch resin cement systems represent superior alternatives to other cement systems.Clinical significance: The clinician should be aware of the differences between various post systems and different cement systems to select and apply the most appropriate post and cement in each clinical situation.
