AI Article Synopsis
- The study assessed the long-term effectiveness of IPS Empress II ceramic onlays for endodontically treated molars over a 4-year period.
- Four failures of the restorations were observed, with issues ranging from debonding to secondary caries, which led to various restorative procedures.
- Despite the failures, the overall success rate was high at 92.5%, indicating that these ceramic onlays are a viable option for restoring compromised molars.
Article Abstract
Purpose: This study evaluated the 4-year clinical performance of IPS Empress II ceramic onlay restorations on extensively restored, endodontically treated molars.
Materials And Methods: A sample of 53 morphologically compromised and endodontically treated molar teeth were restored with IPS Empress II ceramic onlays cemented with a dual cured luting composite. The molars were evaluated by two experienced clinicians in accordance with the modified United States Public Health Service criteria at baseline and 6-month recalls up to a 4-year observation period. The analyses were carried out using the Wilcoxon signed-rank test and the Kaplan-Meier product limit method.
Results: Four failures were noted. Two onlays debonded; one was reinserted and reluted while the other resulted in lost coronal hard tissue and was restored with a fiber reinforced post-and-core system followed by a full ceramic crown restoration. The third failure resulted from secondary caries and fracture of the remaining enamel and was restored with a full ceramic crown. The fourth failure was extracted. None of the onlays exhibited wear, fracture of antagonist teeth, or dimensional change at proximal contacts.
Conclusion: Within the limitations of this study's design and short 4-year observation period, IPS Empress II ceramic onlay restorations demonstrated promising results with a 92.5% success rate.

Objective: This study compared the fracture load, stress distribution, and survival probability under cyclic loading of extensively restored teeth treated with multisonic irrigation with those treated with conventional instrumentation, with or without a post.
Methods: Mesial-occlusal-distal cavities were prepared in 30 human mandibular premolars. The teeth were randomly divided into 3 groups of 10 based on the endodontic and restorative procedures: (1) Root canal treatment (RCT) followed by resin composite restoration (control group), (2) RCT followed by a glass fiber post restoration (conventional group), and (3) minimal instrumentation plus multisonic irrigation followed by resin composite restoration (GW group).
The Effect of Novel Laser-Activated Bleaching Protocols on the Color Change of Non-Vital Anterior Teeth: An In Vitro Study.

Objective: This study compares the color change of non-vital anterior teeth after laser-activated bleaching and conventional walking bleaching technique.
Materials And Methods: Sixty extracted teeth were endodontically treated, stained in a black tea solution, and the baseline shade was measured using a spectrophotometer (Easyshade, VITA). Bleaching was done using either: internal bleaching with 35% HO (Opalescence Endo) and then tooth sealed for 5 days (Gr1), 35% HO (JW Next) for 7 minutes (Gr2), internal and external bleaching for 7 minutes (Gr3), diode laser-activated internal bleaching for 30 seconds (940 nm, continuous wave, 2 W, noncontact mode, 300 um, non-initiated tip), wait for 7 minutes, second laser application for 30 seconds, tooth sealed for 5 days (Gr4), diode laser-activated internal bleaching for 24 hours (Gr5), or diode laser-activated internal and external bleaching for 24 hours (Gr6) ( = 10).

Infected alveolar bone defects pose challenging clinical issues due to disrupted intrinsic healing mechanisms. Thus, the employment of advanced biomaterials enabling the modulation of several aspects of bone regeneration is necessary. This study investigated the effect of multi-functional nanoparticles on anti-inflammatory/osteoconductive characteristics and bone repair in the context of inflamed bone abnormalities.

Background: The fracture of an endodontic instrument within the root canal system can occur during root canal therapy, complicating thorough cleaning and shaping. Consequently, managing the broken fragment becomes crucial.
Methods: Eighty Nickel-titanium (NiTi) #20 K-files (Mani, Tochigi, Japan) were cut 8 mm from the tip, fixed into a corkboard, and classified into five groups (n = 14 each).
Removal of a fractured file beyond the apical foramen using robot-assisted endodontic microsurgery: a clinical report.

Background: Endodontic file fractures are common complications of root canal treatment, and requires removal via specialized techniques such as endodontic microsurgery when the file beyond the apical foramen. It is often challenging to precisely and minimally remove a fractured file. Recently the use of dental autonomous robotic system (ATR) has shown promise in precisely and minimally in dental surgery.
