A Clinical Study on Dental Fluorosis with Light- Induced Fluorescence

The up-to-date dental caries treatments and preventive strategies are related to severel fluoride sources. On the other hand fluoride is present in some nutritional products too. The aim of the present study is to investigate and compare the ability of Quantitative laser fluorescence (QLF) DIAGNOdent Classic and Light-induced fluorescence (LIF), applied with SoproLife diagnostic camera to diagnose Dental fluorosis in mature human teeth n= 180, n= 90 front teeth, n= 50 premolars, n= 40 molars, of 9 patients. The suspected for dental fluorosis patients were as follows four Bulgarians (40 teeth, 4 female patients) from Burgas and five Moldovians (n=140 teeth, 3 female and 2 male patients). All of them were diagnosed with fluorosis according to Luckomski scale. All teeth were exposed to LIF SoproLife (Acteon, France) in modes day light and blue light and to QLF DIAGNOdent Classic (Germany). Moderate and severe dental fluorosis (n = 43 teeth) was diagnosed by QLF-DIAGNOdent Classic device, with scores 99-which indicates dentine caries. Mild fluorosis (n = 137) was diagnosed by DIAGNOdent Classic device, with scores 30-45-56, which indicates dentine caries. DIAGNOdent Classic diagnosed fluorosis as caries lesions. LIF blue light also did not recognizes fluorosis from caries lesions. SoproLife day light showed a realistic appearance of all tooth surfaces.
