Dr. Ben Kew co-authors paper in PLOS One on influence of consumption of acidic and sweetened beverages on salivary friction

Dr. Ben Kew (NAPIC R&I Fellow) has co-authored a paper titled "Short-term effects of sweetened acidic beverages consumption on human saliva: Colloidal properties and protein composition" in PLOS One. In this work led by Dr. Mutahar from School of Dental, Health and Care Professions, University of Portsmouth, Portsmouth, United Kingdom, Dr. Kew and co-authors investigate how consumption of sweetened acidic beverages such as apple juice influence saliva’s lubricating behaviour and adsorbed salivary film characteristics compared to water (control). Findings show that saliva (collected from 32 healthy adults) exposed to water or juice exhibited increased friction when compared to unstimulated whole mouth saliva (uWMS), particularly within the boundary lubrication regime. A one-min rinse with water or juice caused salivary delubrication, with water having a greater delubricating effect (p < 0.05) than that of juice. Strikingly, the friction coefficients reverted to those for uWMS after 10 min (p > 0.05) highlighting the transient nature of delubrication caused by juice consumption. This transient phenomenon was also further demonstrated using quartz crystal microbalance with dissipation monitoring ( QCM-D) measurements. This study highlights temporal effects of juice on salivary delubrication and adsorption. Full text can be found in PLOS ONE 20(9): e0330023.: https://doi.org/10.1371/journal.pone.0330023
