Dental Filling Materials

Key Points

Evaluate the optical properties of different dental filling materials using reflectance spectroscopy.
Conducted diffuse reflectance spectroscopy on six dental materials.
Each material was tested ten times for consistency in reflectivity records.
Included self-adhesive resin, composite resins, and glass ionomer cement for comparison.
Identified distinct reflectivity profiles for each class of dental material.
Healthy teeth showed different reflectivity compared to filling materials, aiding in material identification.

Abstract

Paper related to dental filling materials (Diffuse Reflectance Spectroscopy for Optical Identification of Dental Materials Toward Minimally Invasive Treatment) and 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).
