Effect of pretreatment of root dentin surface with cold atmospheric plasma on improving the bond strength of fiber post and resin cement: In vitro study

Abstract

IntroductionAchieving stable adhesion between fiber post and interradicular dentin is a challenging process in the restoration of endodontically treated teeth. This study was conducted to investigate the effect of surface pretreatment with cold atmospheric plasma (CAP) on improving the bond strength between them.Materials and methodsForty‐eight single‐canal mandibular premolars were cut 1 mm above the cementoenamel junction to keep the root length of 14 mm or more. After endodontic treatment and preparation of the post space, the teeth were divided into four groups regarding the pretreatment of dentin surfaces, including normal saline, ethylenediaminetetraacetic acid (EDTA), CAP, and CAP + EDTA groups. The data were analyzed using paired and independent t‐test and one‐way analysis of variance and the significance level was set at p < .05.ResultsThe bond strength was significantly higher in the coronal third than in the apical third in all the groups. Moreover, the bond strength was significantly higher in the CAP + EDTA‐treated group. The bond strength increased significantly in the CAP group compared to the normal saline group. In addition, the bond strength increased significantly in the CAP or EDTA groups compared to the control group. The lowest bond strength belonged to the control group (normal saline).ConclusionThe surface pretreatment with CAP (alone or in combination with EDTA) played a significant role in improving the bond strength of fiber post and root canal dentin.

The effect of touch-cure polymerization on the push-out bond strength of fiber posts

“…The failure pattern of all samples was assessed utilizing a digital stereomicroscope at 40X magnification (Optica, Italy). The failure form was recorded as follows: an adhesive failure at the cement-dentin and cement-post interfaces, cohesive failure in (dentin, cement, or post), and mixed failure (areas of adhesive and cohesive failure) ( Manouchehri et al, 2023 ).…”
