The current study showed that curcumin has inhibitory effect on polymorphonuclear leukocyte-type MMP-9 involved in matrix degradation in periodontitis. Since Curcumin has a potent anti-inflammatory effect, it may have therapeutic potential as a host modulation agent in periodontal diseases.
Statement of problem:Single maxillary complete denture fracture along the midline due to crack initiation and propagation from stressed areas in shallow palatal vault configuration. Therefore, it is important to use mesh in single denture fabrication.
Aims and objectives:To investigate the mechanical fracture strength of acrylic resin denture base materials using four different mesh designs on shallow palatal vault configuration.
Materials and methods:One type of heat-cured resin denture base materials was used to fabricate specimens. Shallow palatal vault shape stainless steel mold was used to aid in duplicating and standardizing the samples. A total of 100 samples were fabricated with high-impact acrylic resin denture base material using shallow palatal vault configuration and square mesh of dimension 50 × 40 mm was used and samples were divided into 5 groups of 20 samples, and each group contained different mesh designs. These samples were stored in water at room temperature for 4 weeks and will be subjected to fracture test using universal testing machine.
Results:Samples with different four mesh designs, among them there was no significant difference, but fracture strength value of 4 ×4 mm mesh design was slightly more than other groups.
Conclusion:The shallow palatal vault denture base is inherently weaker and less resistant to fracture. Thus, it is recommended to use stainless steel metal mesh in shallow palatal vault to increase fracture resistance. As there was no statistical difference among different mesh designs (i.e., different dimensions of each square in the mesh), any dimension of each square in the mesh can be used without making much statistical difference.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
