“…In this study, plasma was used for 60 s due to the limited root canal space, difficult access of plasma to the entire length of the root canal, and also in order to benefit more from the advantages of plasma application. However, it appears that the time duration selected in this study was insufficient since other studies used plasma for 180 s and reported its optimal efficacy for the enhancement of resin cement bond strength [20,21]. e distance between the nozzle of the plasma jet and the canal orifice was 2 mm in our study, which decreases the plasma penetration into the root canal system.…”

“…Few studies have evaluated the effect of CAAP treatment of root dentin on bond strength of resin cements [20,21]. Prado et al found that argon plasma treatment increased the penetration of the resin sealer into the root canal dentin in the coronal third [33].…”

“…Recent studies [18,19] have shown that surface treatment with nonthermal plasma can enhance the bond strength of the composite to dentin. Some previous studies attempted to improve the bonding of sealers and resin cements by applying CAAP on root canal dentin [20,21]. However, search of the literature yielded no study on its application in the post space considering the complexities of bonding fiber posts to root dentin.…”

Purpose. Debonding from the root canal dentin is the most common failure mode of fiber posts. This study aimed to assess the effects of cold atmospheric argon plasma (CAAP) and ethylenediaminetetraacetic acid (EDTA) on micro-push-out bond strength of fiber posts to root canal dentin. Materials and Methods. Forty maxillary canine teeth were decoronated, underwent endodontic treatment, and were stored in an incubator for 7 days. After post space preparation, the teeth were randomly divided into four groups for different surface treatments: (I) saline, (II) 17% EDTA, (III) CAAP, and (IV) 17% EDTA + CAAP. Fiber posts (Whitepost no. 2, FGM) were cemented into the root canals using Panavia F2.0 resin cement, and 1 mm-thick sections were made at the coronal, middle, and apical thirds of the roots. The samples underwent micro-push-out bond strength test. The mode of failure was also determined under a stereomicroscope. Data were analyzed using three-way ANOVA and Tukey’s post hoc test (α = 0.05). The mode of failure data were analyzed using the chi-square test. Results. The mean micro-push-out bond strength of fiber posts was not significantly different in the four groups ( P > 0.05 ). However, the bond strength values in the coronal third were significantly higher than the corresponding values in the apical third ( P = 0.01 ). There was no significant difference in the modes of failure between the groups ( P > 0.05 ). Conclusion. Application of CAAP alone or in combination with 17% EDTA could not successfully increase the bond strength of fiber posts to root canal dentin.

“…The application of NTAP into the root canal walls provides a better bond strength while using bioceramic-based root canal sealers for obturation procedure. [ 12 ] Hence, NTAP can be used as an adjuvant during endodontic treatment to increase the adhesion property of root canal sealers which might result in a successful outcome.…”

Aim: The aim of this study was to evaluate the effect of nonthermal atmospheric plasma (NTAP) on the bond strength of epoxy resin-based and bioceramic root canal sealers. Materials and Methods: Freshly extracted forty ( n = 40) single-rooted mandibular premolar teeth were divided into four groups ( n = 10) based on the sealer used and NTAP application – Group 1: Epoxy resin-based sealer (AH Plus) without NTAP application, Group 2: Epoxy resin-based sealer (AH Plus) with NTAP application for 30 s, Group 3: Bioceramic sealer (BioRoot RCS) without NTAP application, and Group 4: Bioceramic sealer (BioRoot RCS) with NTAP application for 30 s. After NTAP application in Groups 2 and 4, all the samples were obturated using sealers according to their grouping protocols. Two-millimeter slices were obtained from each sample using hard tissue microtome, which were subjected to push-out bond strength (PBS) under the universal testing machine. Data were subjected to statistical analysis using one-way analysis of variance followed by the Post hoc tukey test. The level of statistical significance was set at P < 0.05. Results: The PBS values were observed to be significantly higher in bioceramic sealer with NTAP application (Group 4) followed by epoxy resin-based sealer with NTAP application (Group 2). Conclusion: NTAP application enhanced the PBS of bioceramic (BioRoot RCS) and epoxy resin-based (AH Plus) sealers compared to their control groups.

“…[27] In addition, it has been demonstrated that CAP changes the physical conditions of root canal dentine by removing the smear layer, thereby opening the dentinal tubules and increasing the hydrophilic property of dentin, thus increasing the penetration depth of the endodontic sealers. [33] Alina et al used a DBD helium plasma jet to treat root canal dentin for 180 s. Pushout tests and confocal microscopy analysis confirmed higher spreading and penetration of both GP and sealer into dentinal tubules. [34] In endodontic practice, the use of fiber posts has gained popularity and is perceived as a promising alternative to cast posts.…”

Cold atmospheric pressure plasmas (CAP) is widely used for various therapeutic applications in health care. With the enormous progress in the understanding of plasma physics and development of plasma devices, the application of CAP is greatly promoted in dentistry. The reactive chemical species and electromagnetic radiation generated by CAP can activate and control various biochemical procedures. Therefore, CAP showed promising usage in surface modification of dental materials, biofilm removal, disinfection, endodontic therapy, periodontitis treatment, wound healing, and head and neck cancer control. Therefore, the objective of the present review is to present recently published studies on CAP in dentistry.
