Effect of modified nanocellulose on improving mechanical properties of flowable dental composite resin

Popis výsledku v původním jazyce

Background: Flowable dental composite resins are widely used in restorative dentistry for the replacement and repair of damaged teeth due to their excellent aesthetic, biological adaptability, low weight and low cost. However, one of the disadvantages of this material is its relatively low mechanical strength compared to other dental materials, which can eventually lead to the initiation and propagation of cracks in composite resin. The use of nano additive materials like modified nanocellulose as filler particles might increase the mechanical resistance of these composite resins. This research investigated the effects of incorporating different weight percentages of the modified nanocellulose particles on the mechanical properties of flowable dental composite resins. Material and Methods: First, the hydroxyl groups of nanocellulose reacted with methacryloyl chloride to incorporate into the polymerization process. After characterization by FTIR spectroscopy and TGA analysis, it was introduced into the flowable dental composite resins. The morphology of the modified composite resin was confirmed by TEM and FE-SEM techniques. Then physical and mechanical properties of prepared composite resins were measured for dental use. Results: The experimental results showed that 2 % modified nanocellulose has a significant increase (about 74 %) in compressive strength of flowable dental composite (P &lt; 0.05). Conclusions: Incorporating 2% modified nanocellulose into flowable dental composite resins can make them more suitable for stressful areas.
