Objectives: This prospective clinical study aimed to determine the influence of oral prosthodontic rehabilitation with partial removable dentures and simplified dietary advice on glycaemic control, nutritional status and oral health-related quality of life (OHRQoL) of older adults with type 2 diabetes.

Background: Individuals with tooth loss who did not wear complete or partial dentures are more likely to be at nutritional risk, suggesting that using dental prostheses would benefit the re-establishment of an adequate nutritional status and potentially improve quality of life. Nutritional therapy is essential for diabetes prevention, treatment and management, favouring glycaemic control.

The global healthcare crisis with the COVID-19 pandemic has placed a significant overwhelming demand for intubation procedures and the need for reliable and accessible video laryngoscopes. The purpose of this scoping and technological review is to provide a comprehensive overview of the current state of the art, covering the period from 2007 to 2022, pertaining to the manufacturing process, characteristics, and validation of video laryngoscopes produced using additive manufacturing techniques. Following the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR), an exhaustive search was conducted across nine prominent databases (PubMed, Web of Science, Scopus, Cochrane, Prospero, Scielo, Embase, Lilacs, Virtual Health Libraries-VHL) and four patent databases (EPO/ESPACENET, WIPO/PATENTSCOPE, National Institute of Industrial Property (INPI), Google Patents).

Antimicrobial and cytotoxic capacity of pyroligneous extracts films of Eucalyptus grandis and chitosan for oral applications.

Sci Rep

November 2021

Post-Graduate Program in Biochemistry and Bioprospecting, Laboratory of Oral Microbiology, Pelotas Dental School, Federal University of Pelotas, 457 Gonçalves Chaves, Room 503, Pelotas, RS, 96015-560, Brazil.

Chitosan films containing distilled pyroligneous extracts of Eucalyptus grandis (DPEC), characterized and developed by Brazilian Agricultural Research Corporation-Embrapa Temperate Agriculture (EMBRAPA-CPACT), were evaluated for antimicrobial activity against Candida albicans, Streptococcus mutans, and Lactobacillus acidophilus by direct contact test. Further, their capacity for the prevention of teeth enamel demineralization and cytotoxicity in vitro were also determined. The natural polymers were tested at different concentrations (1500-7500 µg mL) and the formulation of an experimental fluoride varnish with antimicrobial activity was evaluated by direct contact test, whereas cytotoxicity was analyzed through the colorimetric MTT assay.

To assess the antimicrobial activity and the physical properties of resin-based experimental endodontic sealers with the incorporation of vegetable extracts obtained from Bixa orellana, Mentha piperita, and Tagetes minuta species. The extracts were obtained and characterized by gas chromatography-mass spectrometry (GC-MS), and minimum inhibitory concentration (MIC) against Streptococcus mutans, Enterococcus faecalis, and Candida albicans. The extracts were individually incorporated into a dual-cure experimental sealer at a mass concentration of 0.

To evaluate the bleaching ability, the effect on enamel surface and cytotoxicity of novel tooth-whitening formulations containing papain, ficin, or bromelain. Forty bovine dental discs (6 cm ×4 cm) were pigmentated and randomly allocated into the following groups (n = 10): Group 1, 20 wt% carbamide peroxide (control); group 2, 1% papain-based whitening; group 3, 1% ficin-based whitening; and group 4, 1% bromelain-based whitening. The whitening gels were prepared and applied on the enamel three times per day once a week, for 4 weeks.

Management of skeletal deformities in the maxillofacial region has been an important challenge for medicine and dentistry throughout their evolution as health care sciences. Distraction osteogenesis (DO), also referred to as osteodistraction, is a surgical technique that uses the body's own repairing mechanisms as allies for optimal tissue reconstruction. This method has gained acceptance and joined the conventional techniques for comprehensive treatment of patients with skeletal insufficiencies, and its successful application in the maxillofacial complex has been extensively reported.
