However, staining on posterior teeth was more acceptable than staining on anterior teeth and on primary more than permanent teeth.

Parents' acceptance of SDF treatment is low. However, staining on posterior teeth was more acceptable than staining on anterior teeth and on primary more than permanent teeth.Correctly articulated dental casts are essential for certain dental treatment. Articulation can be traditional using a physical articulator; digital using a physical articulator followed by 3D scanning, or virtual using 3D scanning and software to articulate scans without initial physical articulation. SR59230A This study compared the precision of traditional articulation, using physical centric relation records and an articulator and virtually, by digitally aligning scans of the casts and record. Articulated casts and centric relation records were obtained. 12 record pairs were recorded from the articulated casts. Virtual method all records were scanned, unclamped, in a custom laboratory scanner. The casts were aligned to each scanned record to create virtual articulations. Traditional method each record was used to physically articulate the casts. Each articulation was recorded using an intraoral scanner. The mean inter-arch separation between three key-points on each cast-pair were used to determine differences in occlusal separation in three anatomical directions, and precision of methods. Traditional articulations standard deviations in key-point distance never exceeded 0.102mm. The virtual equivalent was 0.059mm. Statistically significant differences (p⟨0.05) between all anteroposterior separation distances were found between the methods, and in three of six lateral/vertical separations. Virtual articulation was significantly more precise than traditional articulation.

COVID-19 has resulted in the cancellation of general anaesthetic procedures including dental extractions (GAX) for children in the UK, exacerbating existing inequalities. There is robust evidence that children from deprived and some ethnic backgrounds are at greater risk of caries and are, therefore, more likely to be affected by cancellations.

To identify the impact of, and possible mitigations for, cancelled general anaesthetic procedures on children in the South East of England.

Data were collected from service providers on the number of children who had their appointments cancelled during the first lockdown. Paediatric dentists and clinical leads contributed views on the likely impact of these cancellations on the affected children.

1,456 children had their appointments cancelled in the six weeks between 20th March and 30th June 2020. The key themes identified from providers included lengthening waiting lists, challenges of swab testing and self-isolation and the need to re-orientate dental services to increase prevention.

COVID-19 has exacerbated existing health inequalities within our communities. Different parts of the NHS must work together to ensure that all children have access to services to treat and improve oral health.

To develop a utilisation profile for oral examinations performed under the remit of publicly financed dental services in the Republic of Ireland as a proxy for the overall level of service use.

Collation of data from multiple administrative datasets for 2018, and generation of an age-specific oral examination utilisation profile.

Age-specific oral examination rates per 1,000 population.

A total of 1,163,399 publicly financed oral examinations were performed. Comparably low population-adjusted oral examination rates were observed in the 0-15, 16-24 and 75+ age cohorts.

The National Oral Health Policy in Ireland aims to improve access to oral healthcare services across the life-course. Young children and older adults are highlighted as population subgroups with low levels of service eligibility and engagement, respectively. These results reinforce the need to focus on these age cohorts.

In this work, the authors propose a suction-based soft robotic gripper where suction is created inside a self-sealing, highly conformable and thin flat elastic membrane contacting a given part surface. Such soft gripper can self-adapt the size of its effective suction area with respect to the applied load. The elastomeric membrane covering edge of the soft gripper can develop an air-tight self-sealing with parts even smaller than the gripper diameter. Such gripper shows 4 times higher adhesion than the one without the membrane on various textured surfaces. The two major advantages, underactuated self-adaptability and enhanced suction performance, allow the membrane-based suction mechanism to grip various three-dimensional (3D) geometries and delicate parts, such as egg, lime, apple, and even hydrogels without noticeable damage, which can have not been gripped with the previous adhesive microstructures-based and active suction-based soft grippers. The structural and material simplicity of the proposed soft gripper design can have a broad use in diverse fields, such as digital manufacturing, robotic manipulation, transfer printing, and medical gripping.Microneedles are regarded as an emerging and promising transdermal drug delivery strategy. Great efforts are devoted to getting rid of their material restrictions and imparting them with abilities to carry various drugs. Here, inspired by ice formation in nature and based on characteristics of different frozen materials, the authors present novel ice microneedles made from versatile soft materials using a simple freezing template-based fabrication stratagem for effective transdermal delivery of diverse actives. Their strategy can convert microneedles with almost all water-containing components from softness into hardness for guaranteeing satisfactory penetration, thus removing their material component limitations. As all fabrication procedures are mild and actives can maintain activity during these processes, the ice microneedles can carry and deliver various actives from small molecules and macromolecules to even living organisms. They have demonstrated that these ice microneedles can easily penetrate mouse and swine skins using a microneedle injector, with their active-carried tips left inside after their ice base melts.
