The purpose of this investigation was to examine the effectiveness of laser fluorescence for monitoring in vitro remineralization of caries lesions. Seventeen natural enamel lesions in primary molars were each cut into two parts. One part was exposed, at room temperature, to a remineralizing solution (experimental) and the other part to water (control) for(More)
This case report describes the esthetic dental treatment of a patient with Cohen syndrome where microabrasion was used to treat dental fluorosis. The patient's teeth had white and light yellow spots, which were diagnosed as moderate dental fluorosis. These spots were treated with microabrasion using pumice paste and 37% phosphoric acid. The paste was(More)
This in vivo study aimed to evaluate the performance of 2 fluorescence-based methods in detecting occlusal caries lesions in primary teeth, compared with the performance of visual inspection and radiographic methods, and to propose a mathematic correction of the diagnostic parameters due to the imperfect reference standard method used in the study. Two(More)
OBJECTIVES The purpose of this descriptive scanning electron microscopic study was to characterize surface alterations in deciduous tooth enamel after in vitro infrared diode laser irradiation, using a photo-absorbing agent alone and also combined with fluoride, before and after laser irradiation. BACKGROUND DATA Previous investigations have demonstrated(More)
OBJECTIVE The effects of laser-induced compositional changes on the enamel were investigated by energy-dispersive X-ray fluorescence spectrometry (micro-EDX). After cariogenic challenge, we administered treatment of low-level infrared diode laser and a photo-absorbing cream (used to intensify the superficial light absorption). BACKGROUND DATA Dental(More)
OBJECTIVE The aim of this FT-Raman study was to investigate laser-induced compositional changes in enamel after therapy with a low-level infrared diode laser and a photoabsorbing cream, in order to intensify the superficial light absorption before and after cariogenic challenge. BACKGROUND DATA Dental caries remains the most prevalent disease during(More)
The aim of this study was to compare different bacterial models for in vitro induction of non-cavitated enamel caries-like lesions by microhardness and polarized light microscopy analyses. One hundred blocks of bovine enamel were randomly divided into four groups (n = 25) according to the bacterial model for caries induction: (A) Streptococcus mutans, (B)(More)
PURPOSE The objective of this study was to evaluate the presence and severity of dental erosion in cerebral palsy (CP) patients. METHODS A group of 48 noninstitutionalized individuals with CP, 2 to 18 years old (8.8+/-3.9 years), has been diagnosed with the disorder. Dental erosion was evaluated according to O'Brien. Results were compared to a control(More)
OBJECTIVE It is recognized that cystic fibrosis (CF) patients present a risk for oral diseases, since it affects exocrine glands, and the treatment consists of a carbohydrate-rich diet. Recognizing the protective function of saliva on maintaining oral health, the aim of the study was to evaluate salivary parameters in stimulated whole saliva from children(More)
