“…For this reason, immature permanent teeth with necrotic dental pulp suffer from pain, swelling, and sinus tract development in the early stages of disease. A bone lesion can contribute to irrigant extrusion by reducing the resistance provided by periapical tissues, 27 resulting in an outcome similar to that caused by over-instrumentation. Hence, extrusion accidents may be more likely in teeth with non-vital pulps and periapical lesions according to Kleier et al 28 For this reason, treatment should be as conservative as possible.…”

The aim of this study was to compare the amount of irrigant extrusion in simulated immature permanent teeth when the apical diameter and needle insertion depth were varied. Thirty single-rooted maxillary incisors with straight root canals were selected. The root length was standardized to a length of 9 mm. The teeth were divided into two experimental groups according to the degree of apical enlargement (n = 15). The apices were enlarged to a diameter of 1.10 mm or 1.70 mm by using a #3 or #6 peeso reamer, respectively, to simulate immature teeth. The irrigation solution was applied 2 or 4 mm short of the working length (WL) in each experimental group. The glass vial model was used for the collection of extruded irrigant beyond the root apex. A two-way repeated measures analysis of variance test showed that there was no significant difference between different needle insertion depths (2 and 4 mm short of the WL) in the group with an apical diameter of 1.70 mm (p > 0.05). In the group with an apical diameter of 1.10 mm, a 32% increase in irrigant extrusion was observed when the needle was positioned at 2 mm (p < 0.05). Regarding the effect of apical diameter, the group with a diameter of 1.70 mm showed more apical extrusion of the irrigant (34% increase for the needle positioned at 2 mm and 68% increase for the needle positioned at 4 mm). It was observed that the needle insertion depth and apical diameter have a significant effect on irrigant extrusion in immature permanent teeth.

“…The relation of AP with AIRR has been analyzed by different methodologies (3,(7)(8)(9)(10)(11)(12). The incidence, extent and distribution of root canal resorption were evaluated by scanning electron microscopy (SEM) in 100 extracted human teeth with chronic periapical lesions (8).…”

“…Root resorptions (RRs) may show different configurations and destroy the apical root structure more or less extensively. In another study (11), one hundred and four human root apices were used to determine the prevalence of periapical pathologies and their association with the presence and extent of AIRR. Semi-serial sections of soft tissue lesions were stained with hematoxylin and eosin and the root apices analyzed by SEM.…”

Detection of Apical Inflammatory Root Resorption Associated with Periapical Lesion Using Different Methods

et al. 2014

View full text Add to dashboard Cite

The aim of this study was to detect apical inflammatory root resorption (AIRR) associated with periapical lesion using cone beam computed tomography (CBCT) and scanning electronic microscopy (SEM). This clinical study evaluated AIRR in 88 root apexes, from 52 permanent teeth of 14 patients, extracted for different reasons. The patients were submitted to a clinical interview, review of dental/medical histories and clinical/imaging examinations for treatment planning. All selected teeth showed unrestorable condition because of the extensive coronal breakdown due to carious lesions, and root canal infection associated with periapical lesions. CBCT images were obtained from the patients with the aim of diagnosing the periapical diseases which showed complex or doubtful conditions. Two examiners assessed the presence or absence of AIRR. Apices were also analyzed under SEM. Chi-square test was used to compare the imaging methods for detection of AIRR. The level of statistical significance was set at 5%. AIRR associated with root canal infection and apical periodontitis was found in 61.4% of the cases studied by using SEM, and at least half of the cases by CBCT. The microscopic analysis remains as a reference standard against the imaging method to identify AIRR.

“…[2] A number of chemical mediators of inflammation such as cytokines IL-1a,1b,TNFa,prostaglandins and lipopolysaccharides seem to be related to pathogenesis of periapical lesion. [3] Microbial attack and host response events result in apical granulation tissue that is resorption of periradicular bone and degradation of apical periodontal ligament which may turn into cyst. Epithelial lining of radicular cyst arises from epithelial cell rests of malaseez in periodontal ligament.…”
