3D Diagnostic Imaging is commercialising tooth decay detection technology. 3D Diagnostic Imaging took on the technology developed by failed Aim-quoted company IDMoS, which ran out of money, in May 2008. IDMoS had invested the £9m it raised in developing the dental disease detection technology. The device, which became known as CarieScan PRO, was already fully developed and had gained medical approvals but had not been commercialised. The handheld device can be used to monitor tooth decay. It looks like an electric toothbrush and uses a disposable sensor. The sensor is held against each tooth in turn and a tiny electrical current passed through that tooth. A reading is displayed on a screen. A tooth with healthy enamel will impede the electric current. If the current is not impeded as much then dental treatment can be prescribed in order to reverse the process if it is at an early stage. 3D Diagnostic Imaging joined Plus-quoted on 21 April 2009. A share placing at 7p a share raised £200,000, which wais equivalent to the expenses of the flotation. Scottish Enterprise, Evolve Capital and other investors converted £1.8m worth of loan notes at 4p a share. Scottish Enterprise currently owns 29.3% and Evolve 41.2% but they will be diluted by the £2.71m placing at 6p a share. A further £750,000 of loan notes will be converted at 4.5p a share. 3D Diagnostic Imaging joined Aim on 22 November, when it was valued at £10.2m.
