Antifungal Effect on Denture Base Materials using Visible Light Activated Titanium Oxide Synthesized by Two Different Techniques

Abstract

Denture-induced stomatitis (DIS) is the most common form of stomatitis in denture wearing population, with Candida albicans being the principal etiological factor. [1] Candidal load of 65% has been reported in elderly denture wearers and with C. albicans being isolated in 93% of patients with DIS. Candida adheres to polymethylmethacrylate denture acrylic (PMMA) directly or via an intermediary layer of plaque-forming bacteria. [1-3] The intaglio surface of denture is reported to be reservoirs of C. albicans, leading to denture-induced stomatitis and disseminated fungal infections, especially candida induced aspiration pneumonia and pulmonary candidiasis. Aspiration pneumonia is known to be fatal disease in the elderly. [4,5] Despite antifungal therapy to

Carbon dots for effective photodynamic inactivation of virus

“…9 Since UV light is hazardous for broader applications in living environment, various modications to TiO 2 NPs have been made to extend absorption into the visible. [10][11][12] Similarly, the uses of gold NPs with organic dyes, [13][14][15] cationic fullerenes, 16 and semiconductor quantum dots (QDs) [17][18][19] have been explored in the development of antimicrobial agents that can be excited by visible photons. More recently, carbon dots (CDots), which are small carbon NPs with particle surface functionalized by organic molecules, [20][21][22][23][24][25][26][27][28][29][30][31] have been found and demonstrated for their strong visible/natural light-activated antimicrobial functions.…”

Characterization of osteogenic cells grown over modified graphene-oxide-biostable polymers

“…Numerous polymers have been tested for tissue engineering applications with GO, as they easily disperse owing to the copious oxygen groups they contain [7]. The most common biostable polymer is poly (methyl methacrylate) (PMMA), which is extensively used as bone cement [8][9][10][11].…”
