“…25 26 CH alone or in combination with CHX, TAP, and DAP is commonly used as intracanal medicaments. 27 However, their use is associated with some concerns regarding their effects on root dentin. 21 This is especially important for final restoration of tooth crown since endodontically treated teeth have often lost a large amount of tooth structure, and coronal restoration of these teeth requires retention, which is often provided by intracanal posts.…”

Objectives This study aimed to assess the effect of four intracanal medicaments on pull-out bond strength of fiber posts. Materials and Methods A total of 65 single-rooted, single-canal teeth were selected and decoronated. Root canals were prepared and after rinsing were randomly divided into five groups ( n = 13). G 1 : calcium hydroxide (CH), G 2: CH plus chlorhexidine (CH+CHX), G 3 : triple antibiotic paste (TAP), G 4 : double antibiotic paste (DAP) were applied in the canals in the four groups. The control group (G 5 ) received no medicament. After 4 weeks, the medicaments were rinsed off and the canals were filled with gutta-percha. Post space was then prepared in root canals for the placement of glass fiber posts and self-adhesive cement (Panavia F2). After cementation, they were subjected to pull-out bond strength test. Statistical Analysis Data were statistically analyzed using one-way analysis of variance and Tukey test.Results The pull-out bond strength values were significantly different in the groups ( p < 0.001). The highest values of bond strength were seen in G 2 , G 1 , and G 3 (359.97 ± 81.26, 333.79 ± 98.96, 309.27 ± 78.07), respectively. There was no significant difference between G 4 and G 5 ( p = 0.75). Conclusion The results showed that CH, CH+CHX, and TAP enhanced the pull-out bond strength of fiber post to root canal wall as compared to the control group.

“…We observed that calcium hydroxide with 2% chlorhexidine gel did not influence the bond strength values for either material analyzed for coronal sealing, indicating that it is possible to use it safely with regard to its possible impact on coronal sealing in teeth undergoing revitalization procedures. Some studies have analyzed the effects of 2% chlorhexidine gel on bond strength, concluding that this substance yielded higher values than calcium hydroxide and Metapex when MTA Fillapex was used as a filling material [29], although it did not change the bond strength of fiberglass posts cemented with resin cement [30].…”

Objectives The purpose of the present study was to evaluate the effect of calcium hydroxide with 2% chlorhexidine gel (HCX) or distilled water (HCA) compared to triple antibiotic paste (TAP) on push-out bond strength and the cement/dentin interface in canals sealed with White MTA Angelus (WMTA) or Biodentine (BD). Materials and Methods A total of 70 extracted human lower premolars were endodontically prepared and randomly divided into 4 groups according to the intracanal medication, as follows: group 1, HCX; group 2, TAP; group 3, HCA; and group 4, control (without intracanal medication). After 7 days, the medications were removed and the cervical third of the specimens was sectioned into five 1-mm sections. The sections were then sealed with WMTA or BD as a reparative material. After 7 days in 100% humidity, a push-out bond strength test was performed. Elemental analysis was performed at the interface, using energy-dispersive spectroscopy. The data were statistically analyzed using analysis of variance and the Tukey test ( p < 0.05). Results BD presented a higher bond strength than WMTA ( p < 0.05). BD or WMTA in canals treated with calcium hydroxide intracanal medications had the highest bond strength values, with a statistically significant difference compared to TAP in the WMTA group ( p < 0.05). There were small amounts of phosphorus in samples exposed to triple antibiotic paste, regardless of the coronal sealing. Conclusions The use of intracanal medications did not affect the bond strength of WMTA and BD, except when TAP was used with WMTA.

“…Metapex is a new root canal filling material containing calcium hydroxide, iodoform, and silicone oil media. The efficacy of Metapex against bacterial activity in the root canal is superior in comparison to plain calcium hydroxide [ 7 ]. In the present study, Metapex was chosen as a test material given its chemical composition compared to plain calcium hydroxide on the bond strength of sealers and the dentin [ 7 ].…”

This study aimed to compare the effect of 4 different intracanal medicaments on the push-out bond strength of two sealers (AH Plus and MTA Fillapex). 100 single-rooted extracted premolar teeth were divided into 5 groups, with 20 samples in each group, one group being the control group. After cleaning and shaping procedures, the canals were filled with 4 different medicaments: calcium hydroxide, tri-antibiotic paste (TAP), Metapex, or Chlorhexidine (2%) gel for 2 weeks. Following this, the medicaments were rinsed away, and the samples in those sub-groups were obturated with gutta-percha/AH Plus or MTA Fillapex sealers. After 2 weeks of incubation, a 2-mm-thick middle section from each root was evaluated to test push-out strength. The obtained data were tabulated, and appropriate statistical analysis was performed (two-way ANOVA and LSD test). When comparing the average values, the bond strength values of AH Plus were significantly higher than those of MTA Fillapex (p<0.05) in all medicament groups. Based on the findings, we concluded that AH Plus had comparatively higher bond strength than MTA Fillapex. We also observed that AH Plus had higher bond strength in the presence of calcium hydroxide, whereas MTA Fillapex in the presence of Chlorhexidine. A comparison of the push-out bond strength shows that irrespective of the root canal segment or the final irrigant used, AH Plus showed higher values among all groups. The limitation of the current study was that the effect of TAP on the bond strength of endodontic sealers was not negative.
