Comparative evaluation of a novel smart-seal obturating system and its homogeneity of using cone beam computed tomography: In vitro simulated lateral canal study

Abstract

Aim:The aim was to evaluate and compare a novel polyamide polymer based obturating system and Gutta-percha and sealer in filling simulated lateral canals and their homogeneity when used for obturating the root canals.Materials and Methods:A total of 60 freshly extracted human single rooted teeth with fully formed apices were selected for this study. Teeth were de-coronated, and roots were standardized to a working length of 15 mm. Root canal preparation was carried out with rotary Protaper file system in all groups. The specimens were then randomly divided into three groups A, B, and C (n = 20). Ten samples from each group were decalcified and simulated lateral canals were made at 2, 4, and 6 mm from the root apex. Remaining ten samples from each group were maintained calcified. Group A was obturated with SmartSeal system (Prosmart-DRFP Ltd., Stamford, UK). Group B was obturated with sectional backfill method. Group C was obutrated with cold lateral compaction method (control). Decalcified samples from the respective groups were analyzed with digital radiography and photography and the measurement of the linear extension and area of lateral canal filling was done using UTHSCSA (UTHSCSA Image Tool for Windows version 3.0, San Antonio, TX, USA) software. Calcified samples were subjected to cone beam computed tomography image analysis sectioned axially.Results:Group A 92.46 ± 19.45 showed greatest extent of filling in lateral canals and denser homogeneity of oburation, followed by Group B 78.43 ± 26.45 and Group C 52.12 ± 36.67.Conclusions:Polyamide polymer obturation proved to have greater efficiency when compared with Gutta-percha system, when used for obturation with regards to adaptation of the sealer and penetration into the simulated lateral canals.

Push‐out bond strength of root fillings made with C‐Point and BC sealer versus gutta‐percha and AH Plus after the instrumentation of oval canals with the Self‐Adjusting File versus WaveOne

“…Furthermore, it could be assumed that the slow‐setting of the BC sealer combined with the slow expansion of the C‐Point when exposed to moisture may have potentially pushed the sealer into places that lateral compaction with AH Plus sealer could not reach. The results of a recent study by Arora & Hegde () strongly support such a notion.…”

“…The C‐Point consists of a central nylon core made of two polymers (Trogamid T and Trogamid CX) and an outer layer of hydrophilic cross‐linked copolymer of acrylonitrile and vinylpyrrolidone. When exposed to moisture, the outer layer demonstrates nonisotropic radial expansion that is claimed (Arora & Hegde ) to push the BC sealer radially, allowing it to adapt to irregular spaces .…”

“…The pre‐mixed BC sealer is introduced into the canal using either a disposable tip or a lentulo spiral, followed by insertion of a single C‐Point cone (single cone method). The slow‐setting of the sealer (4–10 h) is claimed to allow the C‐Point to expand and push the BC sealer, resulting in intimate contact with the canal walls (Arora & Hegde ). Such a filling system may also be potentially suitable to fill canals with an irregular shape using a single cone technique.…”

Evaluation of the diagnostic yield of dental radiography and cone-beam computed tomography for the identification of anatomic landmarks in small to medium-sized brachycephalic dogs

“…In fact, CBCT is already so well established that the latest CBCT-related studies no longer attempt to prove its superiority to conventional radiography, but instead use CBCT-derived images as the criterionreferenced standard for the localization and description of anatomic landmarks or for postoperative quality assessment of endodontic procedures. 18,19,[23][24][25][26][27][28] However, CBCT has not yet reached similar status in veterinary dentistry.…”

Comparison of Bacterial Coronal Leakage Between Different Obturation Materials (An in Vitro Study)

“…CPoint obturation system (EndoTechnologies, Shrewsbury, USA), also known as Propoint which is a part of the Smartseal obturation system (8) is a novel single-cone hydrophilic system, according to the manufacturer, which provides a three-dimensional seal as it had greater efficiency in filling simulated lateral canals and a comparable homogeneity of obturation (9). CPoint cones contain a central polyamide core to provide good handling with an outer bonded hydrophilic polymer coating, which expands laterally without expanding axially by absorbing residual water from the instrumented root canal space and the naturally present moisture in the dentinal tubules (8).…”
