“…1 The root canal system has a very complex morphology with many irregularities including fins, deltas, and accessory and lateral canals. Lateral canals are reported in 27.4-45% of all teeth, 2,3 and majority are located in the apical third of the roots. 3,4 Reports have shown developing or persistent periapical pathology around untreated and/or unfilled lateral canals.…”

The aim of this study was to evaluate the penetration of a resin/polyester polymer-based material (Resilon Real Seal; SybronEndo Corp., Orange, USA) into simulated lateral canals, and the quality of obturations by different techniques. A total of 30 standardized simulated canals were divided into three groups according to the technique of obturation used: MS (McSpadden), SB (SystemB/Obtura II), and LC (Lateral Condensation). To analyze the penetration of the filling material, the simulated canals were digitalized and the images were analyzed using the Leica QWIN Pro v2.3 software. The data of the middle and apical thirds were separately submitted to analysis of variance (ANOVA), followed by the Tukey's test for the comparison of the techniques. Results showed a significant difference (p < 0.05) between groups (LC < SB) in the middle third, and a significant difference (p < 0.05) between groups (LC < SB and MS < SB) in the apical third. To analyze the quality of the obturations, the canals were radiographed and evaluated by three examiners. The Kappa test on interexaminer agreement and the nonparametric Kruskal-Wallis test indicated no significant difference between filling techniques. It was concluded that Resilon achieves greater levels of penetration when associated with thermoplastic obturation techniques.

“…L ateral canals (1) are difficult to instrument and to irrigate during the endodontic therapy and may allow bacterial growth (2)(3)(4). Although Barthel et al showed no correlation between unfilled lateral canals and inflammation of the periodontal ligament (5), other studies demonstrated a their potential pathogenicity after healing of periradicular lesions in relation with full filling of lateral canals (6 -8).…”

Aims of this work were to examine lateral canals in extracted teeth, to propose a new technique to produce artificial lateral canals, and to compare two obturation techniques. Cleared roots were examined to record measure and shape of lateral canals. Artificial lateral canals were prepared on human demineralized teeth before final clearing. Specimens were divided in two groups: canals of group 1 were filled with Schilder's technique, canals of group 2 were filled with vertical compaction with apical backfilling. Stereomicroscopic analysis of lateral canal filling revealed lower filling rates in apical canals compared to coronal ones and higher filling rates with "vertical compaction with apical backfilling" compared to Schilder's group. The tested procedure appears to be a reliable technique to obtain standardized lateral canals and to compare filling procedures. (5), other studies demonstrated a their potential pathogenicity after healing of periradicular lesions in relation with full filling of lateral canals (6 -8). Key WordsThe capability of an endodontic filling technique to ensure obturation and sealing of thin and irregular ramifications is an important clinical parameter, and may represent a favorable aspect of the filling technique. Among different techniques proposed over the years, the Schilder's technique has been shown to effectively fill lateral canals (9). Brothman (10) demonstrated that vertical compaction of warm gutta-percha approximately doubled number of filled lateral canals if compared to gutta-percha lateral compaction. Recently, the capability of filling lateral canals of a new obturation technique (11, 12) has also been investigated.Several in vitro models have been proposed to compare results of different filling techniques. For this purpose artificial lateral canals were created using various methods and resulting in different shape and size. Wong et al. (13) and Tagger and Gold (14) used a split and hinged hard metal model containing a main canal with extensions mimicking lateral canals, while other authors proposed resin blocks with a main curved canal with lateral ramifications (15-17). Tooth embedded in acrylic block was also proposed (18 -21): the resin block containing the tooth was longitudinally sectioned and root canal irregularities were subsequently produced with a one-half round bur, before re-approximate and secure the two halves. Goldberg et al. (22) created simulated lateral ramifications with reverse taper in human teeth by using a #15 engine reamer to drill into the center of the canal. Similarly Dulac et al. (16) used a #20 K file to fabricate lateral canals in epoxy resin blocks in which simulated root curved canals had been previously mechanically prepared. All these models of lateral canals have diameters greater than natural ones. In fact previous studies showed that 61.3% lateral branches in mandibular incisors and 70.1% in maxillary central incisors had thickness less than #10 reamer (23,24).Considering the high number of in vitro techniques proposed ov...

The interrelationship between endodontic and periodontal diseases has been a subject of speculation, confusion and controversy for many years. Pulpal and periodontal problems are responsible for more than 50% of tooth mortality today. An Endo-Perio lesion can have a varied pathogenesis which ranges from quite simple to relatively complex one. These lesions often present challenges to the clinician as far as diagnosis and prognosis of the involved teeth are concerned. It is very essential to make a correct diagnosis so that the appropriate treatment can be provided. To make a correct diagnosis the clinician should have a thorough understanding and scientific knowledge of these lesions and may need to perform restorative, endoontic or periodontal therapy, either singly or in combination to treat them. Therefore, this paper will highlight the diagnostic, clinical guidelines and decision-making in the treatment of these lesions from an endodontist's point of view to achieve the best outcome.KEYWORD: endoontic or periodontal therapy.
