Diffuse Reflectance Spectroscopy for Optical Identification of Dental Materials

Reflectivity records of 6 different classes with each of observation repeated ten times: (i) Sealant — self-adhesive resin cement (RelyX Unicem), (ii) MatFilling1 — composite resin (Enamel Plus HRi Bio Function BF2), (iii) MatFilling2 — universal composite (GC G-aenial A2), (iv) MatFilling3 — resin-modified glass ionomer cement (RIVA LC A2), (v) healthy teeth (dentin), and (vi) healthy teeth (tooth enamel).
