“… 95 , 100 A variant of IDS undertaken in the access cavity of teeth subjected to endodontic treatment (immediate endodontic sealing) has been shown to reduce coronal leakage, which is the major cause of failure. 101 In a recent study, Ashy et al 8 identified a better marginal adaptation immediately after cementation and a better internal adaptation after thermocycling, when IDS was applied, compared with that using the conventional method (DDS). However, there was no significant difference in marginal adaptation after thermocycling among the two techniques examined.…”

“…Possible benefits mainly concern favorable μTBS values. De Rose et al 2015 101 In vitro Internal adaptation Evaluated the effect of immediate endodontic sealing (Clearfil SE Bond + Majesty Flow/Majesty Posterior) and the composite viscosity on internal adaptation of the final restoration. Immediate endodontic sealing significantly improved internal adaptation compared with that using delayed endodontic sealing, and composite viscosity did not affect internal adaptation.…”

Purpose The immediate application of a dentin-bonding agent after tooth preparation and before impression-taking (immediate dentin sealing [IDS]) has been suggested to provide several advantages concerning bacterial microleakage, hypersensitivity, and bonding quality. We reviewed the literature and clarified certain aspects related to each step of IDS application. Materials and Methods The search strategy comprised an electronic research in MEDLINE, Cochrane, Ovid and Scopus for studies published from January 1990 to December 2020 regarding the IDS technique and including both in vitro and clinical studies. Results After exclusion of irrelevant or duplicate articles, 88 articles focusing on aspects of the IDS technique were assessed. IDS seems to be advantageous with regard to bond strength, gap formation, bacterial microleakage, and dentin hypersensitivity. However, issues arising from interaction with impression materials, the provisional phase, and conditioning methods before cementation require further investigation. Conclusion There are no documented reasons preventing clinicians applying IDS in their everyday practice. On the contrary, the presented technique seems to be beneficial in certain aspects regarding indirect restorations.

“…Wattanawongpitak et al performed an in vitro study investigating coronal root canal dentine showed a significantly inferior microtensile bond strength after etch‐and‐rinse adhesive or self‐etch adhesive application in specimens treated with EDTA followed by NaOCl (Wattanawongpitak et al, 2009). A study of de Rose et al assessing the internal adaptation of composite restorations placed in endodontic cavities by scanning electron microscopy indicated a decline of the adhesive bond to dentine and enamel due to contact with NaOCl (Rose et al, 2015). Since NaOCl is the most effective antibacterial root canal irrigant and essential in endodontic therapy, a sufficiently long NaOCl contact time was selected to allow NaOCl to penetrate the dentinal tubules, and EDTA was applied to remove the smear layer according to best clinical practice (Ayhan et al, 1999; Rossi‐Fedele & Rödig, 2022; Ruksakiet et al, 2020; Violich & Chandler, 2010).…”

Aim The aim of the study was to investigate the influence of cavity cleaning and conditioning on marginal integrity of directly placed post‐endodontic composite class‐I‐restorations in vitro. Methodology A total of 168 fully intact teeth without caries or fillings received pre‐endodontic composite restorations (class‐II) after their extraction. Occlusal endodontic access‐cavities were prepared, and root canals were instrumented and filled with gutta‐percha and an epoxy resin‐based sealer. Prior to post‐endodontic class‐I‐restoration, access cavities were completely contaminated with sealer, cleaned with alcohol and pre‐treated as follows: cleaner only (alcohol), glycine‐polishing, Al2O3 sandblasting, carbide bur (immediate as well as delayed restoration). A positive control (not contaminated with sealer and adhesive used) and negative control (cleaner used but no adhesive) were established. Half of the teeth from each group were subjected to thermocycling and mechanical loading (TCML). Marginal integrity of post‐endodontic restoration was evaluated in oro‐vestibular or mesio‐distal sections after AgNO3 dye penetration (DP) by standardized photomacroscopic imaging and expressed in per cent of margin length along all segments and separately for enamel, dentine and composite, respectively. Results were analysed non‐parametrically (α = .05). Results No restorations or teeth fractured or debonded completely. Without TCML, the median DP of all segments was significantly higher for the negative control compared with all other groups in oro‐vestibular cutting direction (53%; p = .002) and in mesio‐distal cutting direction (51%; p ≤ .041). The other groups without TCML revealed 16%–24% DP (oro‐vestibular) and 12%–24% DP (mesio‐distal). With TCML, the median DP in oro‐vestibular cutting direction for all segments ranged between 48% and 62% for all groups, a significant difference was only observed between glycine‐polishing and carbide bur (p = .041). In mesio‐distal cutting direction, the median DP in negative control was 69% with TCML and significantly higher compared with all other groups (p = .002). For all other groups, the median DP of all segments ranged between 28% and 40% with TCML without significant differences. Error rates method (k = 7) revealed a significant influence of TCML in general on penetration of all segments in both oro‐vestibular and mesio‐distal cutting directions. Conclusion Additional access cavity pre‐treatment after alcohol cleaning did not improve the marginal integrity of post‐endodontic composite restorations. Thorough cleaning of the access cavity with alcohol seems to assure an acceptable marginal integrity to the tooth and restorative composite.

“…Literature has reported improved internal adaptation of composite resin to dentin with IES than with DES. 6 IES can be done in conditions of non-vital teeth where irrigation with NaOCl for dissolution of pulpal tissue may not be required in the initial stages. Whereas in the case of vital teeth, there will be a need for the dissolution of pulpal tissue, which makes the use of NaOCl a must because of its tissue dissolving capacity.…”

Aim: Endodontically treated teeth display altered tooth structure pertaining to various chemical irrigants and intracanal medicaments. To prevent the compromised adhesive bond, dentin biomodification is indicated. This study was designed to evaluate the influence of dentin biomodification on the fracture resistance of root canal-treated teeth following Delayed Endodontic Sealing (DES). Materials and Methods: In 50 maxillary central incisors, Class III cavities along with access cavities were prepared. The samples were randomly divided into five groups. Group 1: Intact teeth ( N = 10), Group 2: Immediate Endodontic Sealing (IES) ( N = 10); Group 3: DES after irrigation with 3% NaOCl ( N = 10); Group 4: DES with 2% chlorhexidine (CHX) as a biomodifier ( N = 10) and Group 5: DES with 5% grape seed extract (GSE) as a biomodifier ( N = 10). In Group 2 samples, composite restorations were done prior to irrigation with 3% sodium hypochlorite (NaOCl). Group 3 samples received root canal irrigation with 3% NaOCl for 1 min, etch and rinse procedure and composite restorations. In Groups 4 and 5, dentin biomodification was done prior to composite restorations. Teeth were subjected to fracture resistance tests. Statistical analysis was carried out employing analysis of variance (ANOVA) and Tukey’s post hoc tests ( p < .05). Results: IES group demonstrated the highest fracture resistance, with a significant difference statistically ( p < .05) when compared with the DES groups. DES modified with GSE resulted in significantly superior fracture resistance compared to DES only, but no statistical difference was present between the CHX and grape seed-treated DES groups. Conclusion: DES with the use of dentin biomodifiers such as 5% GSE and 2% CHX increased the fracture resistance of root canal-treated teeth compared to DES only.
