“…The PBS showed a decreasing trend from the coronal third to the apical third for all groups. These results are similar to other studies, and possible causes may be low or obliterated dentinal tubules in the lower segment, decreased sealer penetration, decreased dentinal tubule density, c-factor, and inadequate cleaning or shaping [10,20]. According to the results of the fracture analysis, the most common type of failure was adhesive and mix type failure in the groups using AH, while cohesive and mix type failures were observed in the groups using BR.…”

“…The irrigation and disinfection protocols affected the bond strength of root canal sealers to root canal dentin [17,18] and photosensitizers used in PDT affect the bond strength of endodontic materials used in the root canal and structure of radicular dentin by creating precipitates or by altering the collagen matrix structure [4,6,12,19,20]. However, there is no knowledge in the literature on the bond strength of BR to radicular dentin after root canal disinfection with PDT.…”

To evaluate the effect of the photodynamic therapy (PDT) using with different photosensitizers on the bond strength of BioRoot RCS (BR) to radicular dentin by comparing with AH Plus (AH). The shaped root canals of 80 human mandibular premolars were divided into four groups based on the final disinfection protocol: NaOCl/EDTA, PDT with methylene Blue (MB), PDT with curcumin (CUR) and PDT with toluidine blue O (TBO) (n = 20). Each group was randomly divided into two subgroups (n = 10), according to the endodontic sealer used for obturation (n = 10). The test of push‐out bond strength (PBS) was performed using an universal test machine. The data were analysed using ANOVA, Tukey post‐hoc, and independent sample t‐test (α = 0.05). MB‐BR group showed the highest PBS at the cervical level (p < 0.05). The selection of the photosensitizer in PDT influenced adhesion of root canal sealers to radicular dentin.

“…The post cavity preparation was conducted using Gates-Glidden and post drills (Cytec blanco, Hahnenkratt), following the method described in the study by Küden et al 36 Post space impressions were obtained following the method of Piangsuk et al 9 Polyvinyl siloxane putty and light body (Express, 3M ESPE), an impression tray, and a post were used to obtain impressions of the post space. Light-body silicone was used to fill the post space initially, followed by the placement of the metal post.…”

This study investigated the impact of common surface pretreatments on the contact angle (CA), surface free energy (SFE), and push-out bond strength (PBS) of custom 3D-printed resin posts. Materials and Methods: Post spaces of 60 endodontically treated mandibular premolars were prepared. Custom 3D-printed posts made from permanent crown resin were fabricated for 50 randomly selected post spaces. The specimens were then divided into six groups (n = 10) based on their surface pretreatment methods. These methods included sandblasting (SB), silane (SL), hydrofluoric acid (HF), and hydrogen peroxide (HP). Additionally, two control groups were established: glass fiber control (GFC) and permanent resin control (PRC). CA and SFE were measured for each 3D-printed post group. PBS and failure mode analyses were conducted. The data were analyzed using the two-way ANOVA followed by the Tukey post hoc test (α = .05). Results: The lowest CA values were found in the SB and SL groups. The SB group had the highest SFE compared to all other groups. SL markedly enhanced the PBS of the resin post compared to the PRC at the cervical, middle, and apical levels (P = .001, P = .000, and P = .002, respectively), and the values were comparable to those of the GFC (P = .695, P = .999, and P = .992, respectively). Except in the GFC, SB, and SL groups, mixed failure decreased from the cervical to apical levels, while adhesive failure rates increased. Conclusions: The application of silane and sandblasting to the surfaces of custom 3D-printed resin posts effectively increased their SFE, thereby enhancing their adhesion.

“… 69 , ozone can be used to disinfect a surface without affecting the adhesion of pit and fissure sealants. However, according to Küden & Karakaş 76 , ozone applied on bleached enamel and dentin restricts the bonding of the composite restoration. In addition, ozone inhalation can be toxic to the pulmonary system and other organs 25 , 70 .…”

Root canal infections are typically polymicrobial and involve strong bacterial interactions. The goal of endodontic treatment is to remove infected content from the root canal system to allow the healing of a pre-existing periapical lesion or to prevent infection of the periradicular tissues. Instrumentation alone is not capable of touching all of the root canal walls. Therefore, the irrigation process is an essential step in the endodontic treatment. However, due to the complex anatomy of the root canal system, this cleaning is very challenging. Although syringe and needle irrigation associated with the use of chemical substances is still the most used method, it does not guarantee optimal cleaning of the root canals. As a result, not only alternative irrigating substances but also numerous activation systems - which are technologies that aim to optimize the action of irrigating substances, both chemically and physically - have been developed. This work aimed to review the characteristics of both classic and current alternatives of irrigating substances and irrigation activation systems.
