Single Cone Obturation versus Cold Lateral Compaction Techniques with Bioceramic and Resin Sealers: Quality of Obturation and Push-Out Bond Strength

Abstract

Objectives. This study compared the obturation quality and push-out bond strength of single cone obturation (SCO) and cold lateral compaction (CLC) with AH-Plus and Sure Seal Root (SSR). Materials and Methods. This in vitro experimental study was conducted on 88 single-rootedsingle-canal teeth with straight roots that were randomly divided into four groups (n = 22). All teeth were decoronated and underwent cleaning and shaping. Obturation was performed with AH-Plus and SCO technique in group 1 (SAH), AH-Plus and CLC technique in group 2 (LAH), SSR and SCO technique in group 3 (SS), and SSR and CLC technique in group 4 (LS). The roots were then sectioned into 3-mm thick slices and underwent digital photography at x25 magnification to assess the quality of obturation in the coronal, middle, and apical thirds by Image J software. The PBS was measured by a universal testing machine. The mode of failure was also determined under a stereomicroscope. Results. The PBS was significantly higher in the LSS group than LAH and SAH groups, and also in the SSS group than the SAH group in all sections. The PBS in the LSS group was significantly higher than SSS in the coronal and middle thirds. Voids were significantly lower in LAH than in the SAH group in all sections. In LSS, voids in the coronal third were significantly lower than in LAH. In the middle third, voids in SSS were significantly lower than in SAH. The groups had no significant difference in the mode of failure ( P > 0.05). The mean percentage of gutta-percha in the use of AH-Plus sealer was significantly higher than SSR ( P < 0.05). The mean percentage of gutta-percha in the coronal third was lower than that in the middle and apical thirds ( P < 0.05). Conclusion. SSR showed higher PBS and less voids than AH-Plus. High PBS of the CLC/SSR group showed that CLC should still be preferred to SCO, and in the case of using SCO, SSR should be preferred to AH-Plus.

Assessing the Sealing Performance and Clinical Outcomes of Endodontic Treatment in Patients with Chronic Apical Periodontitis Using Epoxy Resin and Calcium Salicylate Seals

“…Consistent with prior studies, we observed a substantial reduction in PAI scores following endodontic treatment in both groups [56,57]. In line with other investigations, tooth mobility and pain at the intervention site were significantly reduced after treatment across both sealers [58,59].…”

Prevalence and Morphology of C-Shaped Canals in Mandibular First and Second Molars of an Iranian Population: A Cone-Beam Computed Tomography Assessment

“…Comprehensive knowledge regarding the prevalence and variations of this anatomy can help reduce the occurrence of endodontic treatment failures in these teeth. Recent research has examined endodontic errors and anatomical characteristics of mandibular molars in an Iranian population [19]. However, information on C-shaped canals in this population is lacking.…”

“…CBCT was used in this study because it does not require sectioning or damaging teeth and can be applied clinically [21]. We analyzed existing CBCT scans taken for other diagnostic or treatment purposes, which provided an excellent noninvasive means of obtaining anatomical information [17,19].…”

“…CBCT has been used in complicated cases [17] and provides an excellent educational tool with numerous benefits. Analysis of existing CBCT scans can identify weaknesses in clinical practice, facilitating targeted learning interventions [18,19].…”

“…A recent study examined endodontic errors and mandibular molar anatomy in this population, but it lacked information on C-shaped canals [19]. Considering the significance of comprehensively understanding the prevalence and morphology of C-shaped canals, our objective was to fill this research gap by assessing the prevalence and morphology of C-shaped canals in mandibular molars within the Iranian population.…”
