Functional Near-Infrared Spectroscopy
Yu Chen, Babak Kateb in Neurophotonics and Brain Mapping, 2017
Anesthetized male Wistar rats will be implanted with a fixation device using dental cement, allowing the optic fiber to be near the occipital cortex. Additionally, stainless steel skull screws will be implanted through the skull into the visual cortex (7 mm behind the bregma and 3 mm lateral of the midline) as the positive electrodes. A reference screw electrode will be placed on the midline, 3 mm rostral to the bregma. Dental cement will also be used to fix the screws. One week after, the skin on the head is closed and the animal has recovered from the surgery. After correct signal amplification, filtration, and processing, to evaluate the correlation between the FOS and the electroencephalographic signal, we will evoke visual potentials to evaluate the function of the visual pathway. Light stimulation of the eye evokes visual electrical signals in the visual cortex. The visual potentials are analogous to auditory somatosensory evoked potential, which produce electroencephalographic cortical evoked potentials.
An Introduction to Bioactivity via Restorative Dental Materials

A novel experimental dental cement containing bioactive elements capable of high rates of calcium and phosphate ion release has been investigated by Xie et al. (2019). Materials containing calcium aluminate have also been suggested to be used as a dental cement to prevent demineralization by calcium and phosphate ion release and hydroxyapatite deposition.

Dental ceramics include various glass-based materials, crystalline based materials with glass fillers and polycrystalline solids. The main components of these materials usually are quartz, alumina and other oxides (Shenoy and Shenoy 2010). Dental cement fillings are usually glass-ionomer materials, in which quartz represents one of the main components (Sidhu and Nicholson 2016). Importantly, the various crystalline compounds are radiation sensitive and may exhibit luminescence (Veronese et al. 2010).

Local administration of fluoride antibacterial and antibiotics is another dental application of implants. Dental cement could be blended with stannous fluoride to achieve fluoride sustain release. Hydroxyethyl methacrylate and methyl methacrylate copolymer hydrogel could be used for manufacturing buccally attached hydrogels with the ability to release fluoride at a specific rate (Mohammed Zaki et al. 2012).
