“…This was reinforced by Khayat et al who showed that exposed canals obturated with lateral condensation had total contamination in 28 days while vertical condensation samples were contaminated entirely in 25 days. Recently, reports have been published that suggest failure to provide a definitive restoration by 2 to 4 months after endodontic treatment significantly reduces tooth survival …”

“…CAD/CAM advocates promote the endocrown method as providing improved ceramic adhesive bonding compared to that with amalgam or resin cores, stating that the endocrown preparation provides more dentin surface available for adhesive bonding. Some further anecdotally infer that the adhesive bond to amalgam and/or resin cores is not as effective as that to dentin, while providing expedient coronal sealing that is crucial for the success endodontic treatment . The purpose of this study was to evaluate the failure resistance of CAD/CAM generated molar endocrowns compared to amalgam‐core‐supported, all‐ceramic crowns based on different preparation dentin axial wall height (AWH) features and adhesive strategies.…”

The results of this in vitro test suggests that when suitable tooth structure and sufficient interact restorative space exists, endodontically treated molars restored with lithium disilicate complete crowns based on preparations with amalgam core foundations containing 1 mm and 2 mm of dentin axial wall height could serve as a suitable restorative option that may provide more recoverable failure modes than endocrown restorations.

“…ETT are weakened by the loss of tooth structure from dental caries, tooth fracture, or pre‐existing restoration, but not from endodontic procedures . With a significant loss of tooth structure, ETT should receive a cuspal‐coverage restoration to prevent unrestorable fracture . ETT restored with crowns within 4 months had a significantly higher survival rate than ETT with delayed restoration placement …”

Aim The aim of the present study was to investigate survival rates from fracture of endodontically treated posterior teeth (ETT) restored with or without crowns with recall periods of up to 5 years. Methods ETT with single‐unit crown or resin composite restorations were studied based on the inclusion criteria. Restoration, tooth structure loss, adjacent teeth, fracture, and restorability were recorded. Survival rates from fracture were calculated, and risk factors were identified. Results Overall, survival rate of ETT with crowns (92.2%) was significantly higher than resin composites (77.4%) (P < 0.05). ETT with one or two surface loss/es and two adjacent teeth had a high survival rate of 86.9%, which was not significantly different to ETT with crowns (P ≥ 0.05). Restoration and adjacent teeth were identified as significant factors. The majority of fractured ETT with resin composites were restorable, whereas those with crowns were unrestorable. Survival rates from unrestorable fracture were not significantly different between the crown (93.1%) and resin composite (96%) (P ≥ 0.05). Conclusions The survival rate from the fracture of ETT restored with crowns was significantly higher than ETT restored with resin composites, but was not significantly different to ETT with one or two ETT with one or two surface loss/es and two adjacent teeth. ETT restored with resin composites had mostly restorable fracture, whereas ETT with unrestorable fracture were similar between the two restorations.

“…The crown microleakage is an important factor to bear in mind as a triggering factor of the endodontic treatment failure [2]. For years there has been a lot of emphasis on the quality of the final restoration, for which the intraradicular posts are commonly used to achieve the sealing and provide proper crown support [3]. …”

“…However, the sequence of the later root canal preparation procedures, techniques, and instruments used for removal of root canal filling materials [9], the length of the remaining materials, and time of removal of root filling [10], taking of a post space impression, fitting the intraradicular post in the root canal space and post cementation, may allow the unintended contact of the remaining gutta-percha with saliva and bacteria [3, 11–13]. …”

This study identifies the most common microorganisms present in type III gold cast posts related to pulpal disease and evaluates the sterilization/disinfection method before cementation in the root canal. Forty-five type III gold cast posts were aseptically collected in sterile sealed plastic bags and taken to the microbiology laboratory to carry out the study: fifteen cast posts had no treatment, fifteen were disinfected (immersion in 70% alcohol during 15 minutes), and fifteen were autoclaved at 121°C for 15 minutes by using saturated steam under 15 psi pressure. By using a two-proportion z-test, the difference was statistically significant (p > 0.05) and demonstrates that, in spite of the aseptic pattern used in the cast post collection and laboratory procedures, some cast posts arrive contaminated at the consulting office. The disinfection process worked out in a high percentage and demonstrated that the sterilization by autoclaving eliminated completely the pathogenic microbiota without affecting the cast post shape and integrity that could compromise their final fitting.
