“…200 In comparison, the obturation quality of resin-coated EUR is superior with different obturation techniques (cold lateral compaction (CLC), warm lateral compaction (WLC), and single cone (SC)). 186 The percentages of resin-coated EUR canal filling material are 100% under warm lateral compaction. Therefore, the resin-coated EUR canal filling material is a good choice to obturate the canal space.…”

“…The cross-linked EUR phase considerably improved the permanent deformation of POE, and the tensile set linearly decreased from 134% to 4% with increasing EUR content. In addition, Xia et al prepared a series of SMPs using thermoplastics materials and EUR as a matrix. − The EUR-based SMP has water and thermal response properties. , The EUR/microcrystalline cellulose (EUR/MCC) SMPs showed excellent multiresponsive properties under water and thermal stimulation conditions (Figure b). When the EUR/MCC ratio was 6/4, the EUR/MCC 6/4 SMP presented excellent water/heat double-stimulus shape memory properties ( R f = 95.02%, R r = 90.45%) .…”

As the second natural rubber resource, Eucommia ulmoides rubber (EUR) from Eucommia ulmoides Oliver is mainly composed of trans-1,4-polyisoprene, which is the isomer of natural rubber cis-1,4-polyisoprene from Hevea brasiliensis. In the past few years, the great potential application of EUR has received increasing attention, and there is a growing awareness that the natural polymer EUR could become an emerging research topic in field of the novel materials due to its unique and excellent duality of both rubber and plastic. To gain insight into its further development, in this review, the extraction, structure, physicochemical properties, and modification of EUR are discussed in detail. More emphasis on the potential applications in the fields of the environment, agriculture, engineering, and biomedical engineering is summarized. Finally, some insights into the challenges and perspectives of EUR are also suggested.

“…There are various techniques for obturating the root canal system such as cold and warm lateral compaction, continuous and interrupted waves of vertical compaction, thermo-mechanical compaction, carrier-based techniques and single cone techniques. [1][2][3] Mustaffa M a* , Nordin N b , Embong SNH b , Mohd Ibrahim MS c accepted as a current approach in obturating the root canal system. The obturation quality has been studied by many researchers in aspects of the presence of marginal gaps and voids.…”

“…The obturation quality has been studied by many researchers in aspects of the presence of marginal gaps and voids. [1][2][3][4][5][6][7][8][9] Marginal gaps are defined as a discontinuity at the interface made of two different materials while voids are defined as the vacant area surrounded by the same materials. 5 During obturation procedure, the extrusion of root filling material beyond the apical foramen is sometimes inevitable, especially in patent root canal terminus.…”

INTRODUCTION: This study compared the obturated surface area, the extrusion of root filling material beyond the apical foramen and the duration of obturation procedure in single-rooted mandibular premolar using monocone obturation technique. MATERIALS AND METHODS: The root canal of twenty single-rooted mandibular premolars were prepared, and then divided into two groups; Group 1 (GuttaFlow Bioseal (GFB) and a gutta-percha (GP) cone) and Group 2 (RoekoSeal Automix root canal sealer and a GP cone). The obturation procedure was timed and the obturation radiograph was taken after the procedure. The roots were sectioned perpendicularly and the surfaces were observed under scanning electron microscope. The images were transferred to the SketchAndCalc Area Calculator software for evaluation of the obturated surface area. RESULTS: The median score of obturated surface area in Group 1 and 2 at the apical was 86.51 and 83.00, at the middle was 90.48 and 87.35 and at the coronal was 93.00 and 83.39, respectively. The extrusion of root filling material between two groups did not show statistically significant difference. The mean duration of obturation in Group 1 and 2 was 149.50 and 137.60, respectively. CONCLUSIONS: The obturated surface area at the apical and middle root regions in Group 1 and 2 was comparable but at the coronal region, Group 1 showed 11.5% better coverage. The extrusion of root filling material in Group 1 and 2 was equivalent. Obturation procedure in Group 1 took 8.6% longer than in the Group 2.

“…The evaluation of obturation quality in molars has been the subject of interest that has gained popularity in the recent years [19,[26][27][28]. In the past, the obturation quality has been evaluated in the incisors [29][30][31][32] and premolars [9,[33][34][35][36][37][38], however, changing approaches reflect the need to evaluate the effectiveness of obturation procedures in more complex root canal systems such as multirooted teeth with various root canal configurations and curvatures.…”

The obturation quality of GuttaFlow Bioseal in curved root canals is not commonly investigated although there has been a current approach toward utilizing this material in extracted molars in recent years. This study assessed the obturated surface area, extrusion of root filling material beyond the apical foramen and duration of obturation procedure in curved root canals using monocone obturation technique. Access cavity was prepared in 20 human mandibular molars. Root canals with curvature of more than 10 as determined according to Schneider’s method were included. Samples were prepared using Hyflex CM rotary files and divided into two groups (n=10): Group 1 [gutta-percha cone and GuttaFlow Bioseal] and Group 2 [gutta-percha cone and RoekoSeal Automix root canal sealer]. The duration of obturation procedure was recorded and obturation radiographs were taken. Samples were bisected and the mesial roots were sectioned horizontally to obtain 3 root segments; apical, middle and coronal. All resected roots were mounted on brass stubs, sputter-coated with thin platinum coating and observed under scanning electron microscope (SEM) at 70x magnification. The SEM images were transferred to the SketchAndCalc Area Calculator software. No statistically significant differences in the obturated surface area and extrusion of root filling material were observed between Group 1 and 2, irrespective of the status of root canal curvature. Duration for obturation in severe root canal curvatures between Group 1 and 2 were statistically significant. Obturated surface area and extrusion of root filling material were not affected by the root canal curvature, however duration for obturation using GuttaFlow Bioseal in severe root canal curvatures was slightly longer.
