Orthodontic bracket etchant minimising enamel damage and demineralization
OverviewAdhesive systems for orthodontic brackets, or braces, are required to have bond strength sufficient to prevent failure but not threaten enamel damage upon removal. Tooth damage can result when the bracket and/or residual adhesive is physically removed from the tooth surface. Enamel demineralization is also common problem during tooth real...

Novel self-propelled soft worm like endoscopic robot
Introduction:Academics at King’s College London have developed a novel worm-inspired, multi-segment robotic endoscope with multiple degrees of freedom segments. The novelty of this design is that the robot is able to drive forwards and backwards, anchor itself, steer while inside a tubular structure and control the orientation of an end-mount...

MR Elastography (MRE) for non-invasive diagnosis, staging and monitoring of cancer and fibrosis
Summary The detection of pathological tissue alterations by manual palpation is a simple but essential diagnostic tool used by clinicians. The "virtual palpation" of tissue has now become feasible using Magnetic Resonance Elastography (MRE). Researchers at King’s College London have developed novel MRE units that work alongside s...

Reducing Artefacts in Gradient-Echo MRI using Novel Radiofrequency Pulses
ProblemGradient-echo magnetic resonance imaging (MRI) is used extensively to reveal the structure, and measure the function, of different areas of the body. One particularly exciting application is functional MRI, which can be used to produce maps of brain activity in a subject performing a mental task. Unfortunately signal dropout, caused by dif...

Direct 3D printing of two-component silicone
Summary The system being developed by a team led by a King’s College London researcher is unique in its ability to 3D print a biocompatible two-part silicone required for medical devices such as facial/body prostheses. Silicone formulations have been developed and printed using a modified 3D printer with a custom print head to print room-tem...

Non-Ionising Imaging
Technology OverviewThe technology uses light at a given near infrared wavelength [NIR] to create a transmission image of dental caries (decay). Healthy hard tissues (enamel, dentine and cementum) tend to ‘guide’ light of this wavelength, leading to a bright image, whereas decay and other inhomogeneities cause optical scattering. This pr...

Saliva Guard (Xerostomia Device)
ProblemDebilitating oral dryness (Xeorstomia) is a common, poorly treated component of orofacial cancer radio/chemotherapy and of Sjogren’s disease (an age-related onset auto-immune condition). A device is needed to enhance patient quality of life by reducing pain, ameliorating swallowing difficulty and rampant decay while improving speech a...

Method to identify bioburden in a root canal following preparation
The ProblemBacteria remaining in the root canal (RC) space at the time of completion of a root canal treatment (RCT) can lead to a persistent or secondary infection, which requires revision of the treatment. Currently, there are no methods in widespread use to detect bacterial presence within the root canal space in a fast and reliable manner. Suc...

Segment Based MR-Compatible catheter steering mechanism
The ProblemIncreasingly clinicians are using cardiac ablation to cure atrial fibrillation. During cardiac ablation, energy is delivered through a catheter to areas of the heart muscle causing the abnormal heart rhythm. This energy “disconnects” the pathway of the abnormal rhythm. Recently, the procedures have been extended to more co...
