Hard dental structure conservation by using modern laser fluorescence diagnostic (DIAGNOdent Pen 2190) and minimally invasive treatment – case report

Abstract

Caries diagnosis should be done in the early stages in order to preserve long-term hard dental structures. In addition to that, the cavity lesions treatment should use adhesive materials for crown obturation which allow strictly carious lesion removal and do not require the creation of retention forms, involving an additional sacrifice of dental tissues, thus jeopardizing the tooth resistance. The study presents the case of a 9 years old, male patient who had multiple cavities in the mixed dentition. The designed treatment plan aimed, firstly, at assessing the degree of damage, trough cavities, of the four 6-year molars existing on the arcades and the choice of techniques and materials for coronal restoration following ART concept (Atraumatic Restorative Treatement). Cavities diagnosis was made by combining conventional methods (visual inspection, inspection and palpation by probe, retro alveolar radiography and OPG) and modern methods (laser fluorescence DIAGNOdent Pen 2190). The prime molars 36, 46 treatment consisted in the creation of some VI class cavities, than plugged with glassionomer cement (Fuji IX) due to increased and prolonged release of fluoride, while the 16, 26 molars treatment was achieved by incipient lesions remineralization by topical application of a fluoride varnish containing 5% sodium fluoride (Profluorid varnish, Voco GmbH).
