Objective: To evaluate the efficacy of different fluoride varnishes on white spot lesions (WSL) remineralization. Material and Methods: Polished bovine enamel specimens were obtained (n = 60) had their initial surface Knoop microhardness (SMH) determined. WSL created SMH was measured again. Then, allocated into six groups: C – Control (without varnish); BF Bifluorid 12 (6% NaF + 6% CaF2); DP Du...

background: the purpose of this study is to investigate the relationship between the cognitive impairment and naa/cr and cho/cr ratios in the proton magnetic resonance spectroscopy (1hmrs), and to assess the importance of 1hmrs in the early diagnosis of cognitive impairment in patients with ischemic white matter lesions (wmls). materials and methods: a total of 45 patients (23males and 22 femal...

Tooth decay, at its earliest stages, manifests itself as small, white, subsurface lesions in the enamel. Current methods for detection in the dental clinic are visual and tactile investigations, and bite-wing X-ray radiographs. These techniques suffer from poor sensitivity and specificity at the earliest (and reversible) stages of the disease due to the small size (<100μm) of the lesion. A fine...
