Results of the experimental research which show that the remineralization efficiency of Clinpro TM XT Varnish on early tooth decays lesions, average remineralization depth is 97.1 micro: with D1 (with a demineral depth corresponding to 125.9 microphones) is 86.2 microphones, with D2 (average demineral depth of 252.4 microphones) is 107.9 microphones, are the scientific proofs for interventions on early tooth decay's lesions.
