Резюме
Fluoride ion affects the crystal growth of hydroxiapatite crystals.
Chronic endemic fluorosis leads to elongated apatite crystals with low density
and heterogenic lay down. The up-to-date dental caries treatment and preventive
strategies are related to many fluoride sources. The aim of the present
study was to investigate and compare the ability of quantitative laser fluorescence
(QLF) – DIAGNOdent Classic and quantitative light-induced fluorescence
– SoproLife – lamp and intraoral camera, to diagnose dental fluorosis. Thirteen
molars of 116 extracted mature human molars from the same dental practice
area were diagnosed with fluorosis according to Luckomski scale from 1947. All
teeth were exposed to QLIF – SoproLife (Acteon, France) in modes “day light”,
“macro image”, “blue light”, and to QLF – DIAGNOdent Classic (Germany). All
fluorotic teeth were sectioned in mirror images through the body of stains and
lesions – BL or MD with diamond blade – 0.2 mm and observed under magnification
x5, x30, x100. Results from cross-sectional histology showed sections
with porous enamel, hypomineralized dentine and fissure fluoride caries. Moderate
and severe fluorosis (n = 11) was diagnosed by QLF-DIAGNOdent Classic
device, with scores 99-which indicates dentine caries. Mild fluorosis (n = 2)
was diagnosed by DIAGNOdent Classic device, with scores 30-45-56-, which
indicates dentine caries. DIAGNOdent Classic diagnosed fluorosis as caries lesions.
QLIF also did not recognize fluorosis from caries lesions. SoproLife “day
light” and “macro image” showed a realistic appearance of all tooth surfaces
under magnification x 30-100.
