“…In this study, root filling was performed in specimens with identical root canal anatomy and by a single operator, which makes the technique more reproducible and results more consistent. In primary teeth, some authors found better results NaviTip™ system compared with lentulo or syringe method using Vitapex ® as obturating material and better results for pressure syringes compared with lentulo for delivering Endoflas . Important to note that both studies used low resolution, bidimensional, and subjective evaluation techniques.…”

“…Many laboratorial studies have been designed to investigate the effectiveness of different obturation techniques and filling materials for primary teeth, but most of them used radiographs or conventional tomographic evaluations . Although both techniques have very low spatial resolution (ranging from 100 to 1000 μm), radiographs have also de limitation of being a bidimensional evaluation.…”

Background Achieving a void‐free root canal filling is a challenge in current clinical pulpectomy practice. Aim To compare filling effectiveness and internal voids of root filling materials and obturation techniques in resin‐prototyped primary incisors by micro‐CT. Design Fifty prototypes were instrumented and randomly divided (n = 10) according to the filling materials (Vitapex®, ZOE, Calcicur®, Feapex, and Calen®‐ZO) and obturation technique: lentulo or pressure syringe (n = 5). The specimens were micro‐CT scanned (pixel size = 7.83 μm) and reconstructed, and the total volume of filled canal (%FC) and internal voids (%IV) of the bulk filling material was calculated. Kruskal‐Wallis and Mann‐Whitney tests were used to detect differences and interactions among groups. Results Calen®‐ZO, Vitapex®, and ZOE showed similar %FC. Calcicur® showed lower %FC compared with Calen®‐ZO, Vitapex®, and ZOE (P < .05) but similar to Feapex. No statistically significant differences in %FC between lentulo or pressure syringe were disclosed. Regarding %IV, Vitapex®, and Calen®‐ZO performed better with syringe, although Calcicur® was better with lentulo. The number of voids in the obturation bulk was similar among materials, but always lower (P < .05) in syringe filled specimens. Conclusion Vitapex®, Calen®‐ZO, and ZOE outperformed Calcicur® and Feapex in %FC and if the syringe technique is used, %IV of the obturation bulk and presence of defects was lower.

“…The ideal obturating technique should ensure a good apical seal without any underfilling or overfilling . Traditionally, zinc oxide eugenol (ZOE) has been the material of choice for filling root canals of primary teeth due to ease of handling, operator feasibility and cost‐effectiveness.…”

Aim Physical properties of obturating materials have a direct effect on the quality of obturation; less viscous material will tend to extrude beyond the apex. We hypothesize that the use of absorbable gelatin sponge (AGS) can prevent the extrusion of these materials. This study aimed to evaluate the quality of obturation in root canals filled with iodoform‐calcium hydroxide (Metapex) premixed paste and Metapex with AGS (MAGS) in primary molars. Methods This in vivo study comprised 60 primary mandibular molars which after instrumentation were divided into 2 groups according to the obturation material used, Metapex and MAGS, followed by radiographic evaluation to assess the quality of the obturation. The χ2‐test was applied for statistical analysis. Results There was a statistically significant difference between Metapex and MAGS groups in achieving optimum obturation (P < .001). Metapex and MAGS exhibited 86.65% and 38.88% optimum obturation respectively. The overfilling of root canals effectively reduced from 38.88% to 4.44%. Conclusion The addition of AGS to Metapex causes a “tamponade effect”, which reduces the tendency of Metapex to extrude beyond the root apex. Root canal obturation using a modified filling paste like MAGS is effective in obtaining optimum obturation in primary teeth.

Pulp therapy helps in preserving a pulpally involved primary tooth by eliminating bacteria and their products and ensures hermetic seal of the root canals so that the primary tooth can complete its function without harming the successor or affecting the health of the patient. A thorough understanding of the pulp morphology and root formation and resorption in primary teeth as well as different materials and techniques used is imperative for a successful pulp therapy. One of the major areas of continued research is in the area of finding obturating materials to suit the specific properties of these teeth. This article seeks to present a review of the major obturating materials and techniques with their modifications as well as their advantages and disadvantages.
