Defects detection in dentistry: designing a graphene multi-layered based plasmonic sensor

Abstract

Dental Restorative materials play a very important role in solving the issue of sensitivity in human teeth. Many such materials, based on their respective optical properties, are considered for various usages viz. cavity treatment, reparation of cracked or broken teeth, detection of plaque formation, etc Another way is to deal with different restorative materials for dentistry application which should be ideal and appropriate. Surface Plasmon Resonance (SPR), being an optical phenomenon, has the capability to analyze the optical properties which may be used for Bio-medical Applications also. Considering the adsorption efficiency (to bio-molecules) of Graphene material can be applied for detecting any plaque formation in the essential components of a human teeth viz. Enamel, Dentin and Cementum. Sensitivity, Figure of Merit (F.O.M.) calculations and the correlation between refractive index of different dental restorative materials and their concentration percentage have been tabulated in this manuscript. SPR curves have been obtained using MATLAB environment and Characteristic Transfer Matrix (CTM). A new theoretical approach to detect the teeth-health with harm free (without X-ray source) technique has been proposed. A new technique is considered to determine the quality (cavity formation and others) of teeth-hygiene using less health-hazard radiation. LASER beam-based SPR phenomenon is projected here to identify the tooth condition, which may be implemented for the application purpose.
