Best insight from top research papers

The preparation design for endodontically treated teeth varies depending on the type of substance used. Lithium disilicate crowns can be used to restore these teeth, and both planar and flat occlusal designs have shown successful clinical performance . Another option is the use of Endocrowns, which are adhesive restorations with minimally invasive preparation. The preparation design should provide retention, stability, and structural durability to the restoration . Nonvital teeth can be restored using a ferrule effect, which involves encircling the tooth with cast metal to improve its integrity and minimize fracture . Endocrowns, on the other hand, are one-piece restorations that can be used in cases with decreased crown height. The preparation includes a "sidewalk" cervical margin and a preparation into the pulp chamber, and it relies on adhesive procedures for stability and retention . The type of substance used also affects the type of restorations that can be placed, such as direct-bonded resin-composite restorations for intact posterior teeth .

Which concentration of NaOCl solution should be used in endodontics?2 answersThe optimal concentration of sodium hypochlorite (NaOCl) solution to be used in endodontics is still a topic of debate. However, the literature suggests that concentrations ranging from 0.5% to 6% are commonly used. Studies have shown that NaOCl at concentrations recommended for regenerative endodontics (1.5% and 5.25%) did not have a significant effect on the mechanical properties of dentin. It has been reported that NaOCl has excellent properties such as high antimicrobial activity and tissue dissolving capabilities, but it also has disadvantages such as the inability to remove the smear layer alone and potential toxic effects on surrounding tissues. Therefore, the choice of NaOCl concentration should be based on the specific clinical situation and the desired outcome of the treatment. Further research is needed to determine the ideal concentration of NaOCl for effective and safe irrigation in endodontics.

Water impacts adhesive bond strength through various mechanisms. One significant mechanism is the hydrolysis of the adhesive due to water absorption, leading to a decrease in bonding strength over time. Additionally, the diffusion of water into the adhesive layer and subsequent attack on the interface contribute to weakening the bond. Critical to this process is the build-up of local water concentration near the interface, causing interfacial swelling stresses and weakening of interfacial bonds, ultimately leading to a loss of adhesion. Furthermore, the presence of water content in adhesives affects their physicochemical properties, such as degree of conversion, flexural strength, modulus of elasticity, and compressive strength, influencing the overall bond strength.What climatic variables influence biomass growth in ecosystems?
