Abstract

The conventional denture base resins had many drawbacks. Hence, the objective of this study was to compare the effect of incorporation of silver nanoparticles on mechanical properties of light-cured resin material. Materials and Methods: Specimens of acrylic resin (control group) and acrylic resin reinforced with 2% silver nanoparticles (test group) were evaluated for mechanical properties such as impact strength, transverse strength, modulus of elasticity, and deflection. Unpaired t test was used for statistical analysis. Results: Mechanical properties of light cure reinforced with silver nanoparticles were significantly higher than conventional light-cured resin (P < 0.05). Conclusion: The incorporation of silver nanoparticles into light-cured resin increases the mechanical properties making it more stronger material.

Abstract

Aim: Aim of the present study was to evaluate the prevalence of dental caries and periodontal status among Down’s syndrome population in Riyadh City. Materials and Methods: A total of 81 male Down’s syndrome subjects were examined in this study. All subjects were recruited from the Saudi Center for Down Syndrome, Riyadh. Clinical examination was carried out by a single precalibrated examiner. Dental caries experience was counted according to the DMFT (decayed, missing, and filled teeth) indexes. Periodontal status was evaluated by using plaque and gingival indexes. Statistical analysis was performed using SPSS 19 version. Consequently, Pearson chi-square test and Fisher exact test was used to calculate p-value for parametric variables. Results: In this study 11.1% of the subjects were not having any decayed teeth, 39.5% were not having any missing teeth, and 55.6% were not having any filled teeth. In plaque index, maximum number of subjects in all the age group were in the fair group, and there was a highly significant (P value
