Stress Analysis on Mesiolingual Cavity of Endodontically Treated Molar Restored Using Bidirectional Fiber-Reinforced Composite (Wallpapering Technique). Clin Cosmet Investig Dent 2024; 16:75-89. [PMID: 38632981 PMCID: PMC11022878 DOI: 10.2147/ccide.s450325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 03/27/2024] [Indexed: 04/19/2024] Open
Abstract
Introduction Endodontically treated teeth (ETT) undergo extensive structure change and experience high stress during biomechanical function. Stress distribution is influenced by the restoration material and the type of bond between material and tooth structure. The selection of materials that can distribute stress will affect the resistance and retention of ETT to mastication forces, thus biomechanical functions were achieved. Composite has mechanical properties similar to dentin, it can transmit and distribute stresses throughout the tooth surface. The disadvantage of composites in large cavities is their lack of toughness. The addition of fiber to composites can increase their toughness. Purpose This research is to determine the stress distribution of a fiber-reinforced composite made of polyethylene and e-glass on the mesiolingual cavity of ETT. Materials and Methods A three-dimensional model of the mandibular molar was prepared for cavity preparation and the formation of restorations using SolidWorks 2021. The models were analyzed with Abaqus 2020 to determine stress concentrations after given vertical and oblique loading. Results The maximum and minimum principal stress data were obtained to assess material resistance and interfacial damage criterion. Polyethylene fiber shows a more homogeneous stress distribution because the modulus of elasticity is close to the dentin and has a thickness that can reduce the volume of the composite. The E-glass shows the stress concentration on the circumferential fiber and cavity floor. Conclusion The stress distribution of fiber-reinforced composite on the buccolingual cavity of ETT using the finite element method did not show structural failure in the polyethylene group because the maximum and minimum principal stresses were lower than the strength of the material. Interfacial bond failure occurs at the enamel portion. The maximum and minimum principal values of e-glass indicate structural failure in the circumferential fiber and the base fiber because the stress exceeds the strength of the material. Interfacial bond failure occurred on the circumferential and the cavity floor.

Exploring wound management in dental pulp: Utilizing single-cell RNA sequencing for global transcriptomic analysis in healthy and inflamed pulpal tissues. Int Wound J 2024; 21:e14804. [PMID: 38385817 PMCID: PMC10883240 DOI: 10.1111/iwj.14804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 02/05/2024] [Accepted: 02/06/2024] [Indexed: 02/23/2024] Open
Abstract
The process of wound healing in the dental pulp is characterized by intricate interplay of signalling cascades, cellular responses, and extracellular matrix (ECM). The objective of this research was to examine the intricate interaction between signalling cascades, cellular responses, and extracellular matrix (ECM) dynamics that comprise the wound healing process of dental pulp. We conducted a controlled laboratory analysis of transcriptomic landscape of dental pulp tissues, including both healthy and inflamed samples, utilizing single-cell RNA sequencing. We identified significant change in cellular composition under carious conditions by analysing samples from 50 patients. Specifically, the proportion of immune cells increased from 25% to 40%, while the proportion of fibroblasts decreased from 20% to 10%. A transition towards ECM remodelling and fibrosis was indicated by this change. In addition, substantial increase inexpression of critical genes including COL1A1, FN1, IL-1B, IL-6 and TNC was detected, indicating that the extracellular matrix (ECM) was actively remodelled and that a robust inflammatory response was present, both of which are vital for tissue repair. Increased cell-cell interactions among B cells, plasma cells, macrophages and MSCs, and fibroblasts were highlighted in our study, demonstrating the intricate cellular dynamics that occur in response to dental pulp injury. The knowledge gained regarding the cellular and molecular processes underlying pulp wound healing contributed to the advancement of knowledge regarding pulp pathology and regeneration. Moreover, it established a foundation for creation of targeted therapeutic interventions that seek to maximize pulp repair and regeneration. This study represented noteworthy achievement in the field of dental surgery, establishing a solid groundwork for subsequent investigations into regenerative medicine, wound healing, and dental tissue restoration.

Abstract
Introduction In vitro fracture resistance of extracted mandibular molars treated with various access cavity designs, including traditional endodontic cavity (TradAC), conservative/contracted endodontic cavity (ConsAC), ninja endodontic cavity (UltraAC), truss endodontic cavity (TrussAC), caries-driven access cavity (CariesAC), and intact teeth, is the focus of this study. Materials and Methods Six groups of 20 mandibular molars, totaling 120, were used in the investigation. While the other five groups underwent various access cavity preparations, chemomechanical preparation, and obturation procedures before being repaired with composite resin, Group 1 was left unaltered (the control). A 6 mm round head tip was used to apply the fracture force, which was measured in newtons, at a crosshead speed of 1 mm/min until fracture developed. Results According to the current study, the intact control group had the maximum fracture resistance. The access cavity groups' mean values were maximum in CariesAC followed by ConsAC, TrussAC, UltraAC, and TraditonalAC respectively. Conclusion While among the four minimally invasive designs, CariesAC showed a higher fracture resistance despite the results being statistically insignificant, TradAC had a significantly lower resistance than other conservative access cavity designs.

Abstract
Aim To compare the sealing ability of three different materials when used as postendodontic restoration barriers to coronal microleakage in root-filled teeth. Materials and Methods In the present study, 60 single-rooted mandibular premolars with single canals were selected. After endodontic treatment was done with protaper files, they were divided into three groups of 20 teeth each, which were restored with Zirconomer (Group I), Hi-Dense (Group II), and Surefil composite (Group III), respectively. After storing in artificial saliva for 10 days, all teeth were then immersed in Rhodamine 6G fluorescent dye. Teeth were then sectioned buccolingually in a longitudinal direction. The coronal microleakage was measured in both halves under a fluorescence microscope and images were taken with a digital camera. Data obtained from the study in the form of scoring as per specific criteria was subjected to statistical analysis. Result Results of the study showed that the minimum amount of coronal microleakage was seen in Group II restored with Hi-Dense followed by Group III restored with Surefil Composite and the maximum amount of coronal microleakage was seen in Group I restored with Zirconomer. Conclusion On the basis of the results of the present study, it may be concluded that Hi-Dense showed better coronal sealing ability in access cavities. Surefil composite exhibited coronal microleakage less than Zirconomer but more than Hi-Dense.

Abstract
Introduction The utilization of endodontic sealers is of paramount importance in ensuring the sustained efficacy and resilience of endodontic treatment. The primary objective of the research was to appraise and contrast the fracture resistance (FR) of three distinct categories of endodontic sealing materials that are frequently employed in the context of endodontic therapy. Materials and methods This research used an in vitro experimental design. Sixty single-rooted human teeth indicated for extraction were utilized according to established protocols. These teeth were then arbitrarily divided into four piles, one for each of the four possible sealants. All specimens were put through a standardized thermal cycling procedure to simulate clinical conditions after the root canals were obturated. The subsequent step involved testing the FR of each group by utilizing a universal testing machine up until failure. Any statistically significant difference in FR among the three sealing materials was identified through appropriate statistical analysis. Results Group 1, which utilized a particular sealing material, exhibited the highest mean fracture resistance, measuring at an impressive 1198.33 ± 321.4 Newtons (N). A post hoc analysis was done to see the exact differences between each group and statistically significant differences between Groups 1 and 2 (p<0.05), Groups 1 and 4 (p<0.05), and Groups 3 and 4 (p<0.001) were observed. Conclusion The FR of Group 1 specimens were noticeably greater than those of Group 2 and Group 4 while the FR of Group 3 specimens was more than that of the Group 4 specimens. This study provides important insights into the fracture resistance of various endodontic sealing materials.
