Tooth enamel associated with EPR detection is a very promising natural dosimeter. When conducting retrospective dosimetry, attention should be paid to recent restorations on teeth (less than 6 month), specially for doses lower than 3Gy because dental resins exhibit intense EPR signals early after photopolymerization
