Cytotoxicity and Biological Activities of Geopopolis Extract from the Stingless bee (Melipona scutellaris) in Isolates of Staphylococcus aureus.

Geopropolis resins are produced by stingless bees (Meliponinae), developed from the collection of resinous materials, waxes and exudates, from the flora of the region where stingless bees are present, in addition to the addition of clay or earth in its composition. Several biological activities are attributed to Ethanol Extracts of Geopropolis (EEGP). The bioactive properties are associated with the complex chemical composition that the samples have.

Effects of long-term cinnamaldehyde immersion on the surface roughness and color of heat-polymerized denture base resin.

Statement Of Problem: Cinnamaldehyde has been successfully used for the short-term disinfection of dentures; however, its long-term effects on the surface and color properties of denture base materials remain unknown.

Purpose: The purpose of this in vitro study was to evaluate the effects of simulated immersion in cinnamaldehyde for up to 5 years on the surface roughness and color parameters of a heat-polymerized denture resin.

Material And Methods: Eighty Ø10×5-mm disk-shaped specimens were prepared from microwave heat-polymerized polymethylmethacrylate (PMMA) and immersed in 4 solutions (n=20): TW-tap water (control), SH - 0.

Safety and tolerability of cinnamaldehyde in orabase for oral candidiasis treatment: phase I clinical trial.

Objective: To advance studies on the effect of a new pharmaceutical formulation for the treatment of oral fungal infections, we evaluated the safety and tolerability of orabase ointment containing cinnamaldehyde for use on the oral mucosa.

Material And Methods: A clinical trial (phase I) was carried out on 35 individuals with healthy oral mucosa divided into three groups: ointments at 200 µg/mL, n = 12; 300 µg/mL, n = 11; and 400 µg/mL, n = 12. Product safety was assessed using three parameters: (a) clinical evolution as recorded by trained examiners; (b) evolution of the inflammatory process as registered by an exfoliative cytology exam and analyzed by trained pathologists; (c) mucosal swab to count Candida spp.
