AIM To evaluate chemically the effects of diode laser on fluoride uptake before and after laser irradiation of enamel surfaces. METHODS Crowns of 20 sound human teeth were halved and a 3 x 3 mm acid-resistant varnish uncovered window left for: A) no treatment; B) fluoride (Elmex gel); C) diode (fluoride + diode laser); D) diode (diode laser + fluoride). The dental surfaces were analysed using...

The application of topical fluoride after acid-etching substantially reduces the risk of enamel opacities and caries, but fluoride treatment can reduce strength of the enamel-adhesive interface to a measurable extent. In this in vitro study there was a slight reduction (statistically inconsequential) in bond strength with the use of 2.0% aqueous NaF. In contrast, two acidulated solutions tested...

BACKGROUND Orthodontic treatment has gained popularity since beginning of era of dentistry. Now a day, everyone is conscious about their appearance, smile and function. During orthodontic treatment use of brackets and adhesives are common. The bonding of brackets will cause demineralization which requires the fluoridation. So the study has been under- taken to analyze the pattern of fluoride re...

OBJECTIVE To determine the frequency and associated factors of visits to the dentist in the last year by Nicaraguan schoolchildren to receive professionally applied topical fluoride (PATF). MATERIAL AND METHODS A cross-sectional study was designed in children from public schools in the city of León, Nicaragua, were included. A series of socioeconomic, sociodemographic, and behavioural variabl...

It is well established that fluoride plays an important role in the prevention of dental caries. Fluoridation of drinking water has been a successful public health measure in reducing the prevalence of tooth decay.' Beneficial results have also ensued from incorporation of stannous fluoride into a dentifrice.2 Wellock and Brudevold3 and others4,5 have reported a reduction in carious surfaces, a...

One of the common chronic inflammatory skin diseases is Acne Vulgaris that affects up to 80% of a teen-age population. The progress of acne lesions is due to colonization of Propionibacterium acnes (P .acnes) in hair follicles. Treatment of acne includes topical or systemic therapy or combination therapy, with a tendency to perform topical therapy in mild to moderate acne. Nanoemulsions, small ...
