Whilst this guidance seeks to ensure a consistent UK-wide approach to prevention of oral diseases, some differences in operational delivery and organisational responsibilities may apply in Wales, Northern Ireland and England. In Scotland the guidance will be used to inform oral health improvement policy.

SFM also provides with a unique possibility to correlate nanoscale heterogeneities in the surface topography ( Fig. 5a) and the mechanical landscape ( Fig. 5b) observed in the presence of Cd 2+ ions. The force curves extracted from 2 × “higher” positions ( Fig. 5c) and 2 × “lower” positions ( Fig. 5d) showed distinctly different increases. Although the quantification of mechanical parameters, such as Young's modulus, from the force curves was not possible with our multilayered lipid/polymer systems, a sharper increase in Δ f shown in Fig. 5c suggests that the higher regions (protrusions) are stiffer than the lower region showing a markedly slower increase, as schematically shown in Fig. 5e.

Cleaning between teeth, ideally with interdental brushes, is recommended prior to toothbrushing as a habit-forming approach, which is considered to be good practice [footnote 9] through adult life. Introduction Stimuli-responsive polymers have attracted interest for use in various drug delivery and microencapsulation applications because these substances can protect and/or release materials in response to the surrounding environment. 1 In particular, polyelectrolyte brushes have been grafted on surfaces to give the materials adaptable functionalities. In these cases, the physical properties of the surface can be modulated based on the electrostatic properties of the external media ( e.g., pH and salt concentrations). 2–4 The structures and mechanical properties of polymer brushes have been measured experimentally using X-ray/neutron reflectivity, 5,6 quartz crystal microbalance with dissipation (QCM-D), 7,8 tribology, 9,10 and microinterferometry. 11,12

In this study, we functionalized the surface of planar lipid membranes ( i.e., supported membranes) 22,23 with poly(acrylic acid) brushes bearing cysteine side chain functional groups (pAA-Cys) by incorporating the lipids covalently coupled with pAA-Cys ( i.e., DOPE-pAA-Cys5) into the matrix lipids ( Fig. 1). In these materials, pAA-Cys5 moieties interact with divalent Cd 2+ ions similar to naturally occurring proteins 24 because pAA-Cys has both –SH and –COOH groups. We investigated how pAA-Cys brushes adapt their structure and mechanical landscape near the interface following the addition of Cd 2+ ions. We used lipids and lipopolymers with identical hydrocarbon chains to prevent phase separation. 25 The lateral average distance between lipopolymer molecules 〈 d〉 can be precisely controlled by taking advantage of the self-assembling nature of lipids and lipopolymers and tuning the molar fraction of lipopolymers χ lipo, such that Delivering Better Oral Health has been developed with the support of the 4 UK Chief Dental Officers.
