Long term antifungal efficacy of silver ‑zinc zeolite nanoparticles incorporated in two soft denture liners ‑ An in vitro assessment
Conclusion: SZZ ‑NPs 0.5%w/w, 2%w/w, and fluconazole 5%w/w can be incorporated with softdenture liners against C. albicans. Fluconazole 5%w/w is the recommended choice for short ‑termantifungal efficacy, while SZZ ‑NPs 2%w/w is recommended when long‑term antifungal efficacy isneeded. GC soft denture liner was the recommended choice.Key Words: Candida albicans, drug delivery systems, drug resistance, nanoparticles, zeolites (Source: Dental Research Journal)

Single ‑visit nonsurgical endodontic treatment of maxillary sinusitis: A case series
The etiopathology of maxillary sinusitis of dental origin (MSDO) is well established, and chronicapical periodontitis is the second most common cause of all dental ‑induced sinusitis incidents.The literature presents no common treatment protocols for MSDO and very few studies addressthe impact of root canal treatment (RCT) in its management. The literature presents cases ofmaxillary sinusitis resolution after performing a multivisit nonsurgical endodontic treatment, yetnone described complete healing of MSDO as a result of single ‑visit nonsurgical RCT. This paperreports a case series of maxillary sinusitis of endodont...
