Aim. The aim of this study was to compare the effect of pH cycling on the microhardness of the enamel of primary human teeth treated with a conventional brown Sodium Fluoride (5% NaF) Varnish to those treated with a white Fluoride Varnish (5% NaF) enhanced with functionalized tricalcium phosphate (fTCP). Materials and Methods. Ninety extracted caries-free primary incisors were washed in a deter...

The purpose of this study was to evaluate the effect of the application of fluoride products on the development of enamel caries in deciduous teeth. A total of 108 deciduous teeth were chosen for the study. Acid-resistant varnish was applied on the teeth, leaving only one area of 5 mm x 1 mm of dental enamel exposed. The teeth were allocated randomly to one of the following groups: 1) control -...

AIM To evaluate the effect of fluoride varnish on Streptococcus mutans count in saliva among 12-year-old school children. MATERIALS AND METHODS A field experiment was conducted to evaluate the effects of fluoride varnish on S. mutans count in saliva among 12-year-old school children. A total of 42 school-going children attending schools in Vadodara district, Gujarat, India, were divided into ...

BACKGROUND The Scottish Government set out its policy on addressing the poor oral health of Scottish children in 2005. This led to the establishment of Childsmile, a national programme designed to improve the oral health of children in Scotland. One element of the programme promotes daily tooth brushing in all nurseries in Scotland (Childsmile Core). A second targeted component (Childsmile Nurs...

Rock varnish, erosional grooves, and well-developed cavernous weathering phenomena occur in close association on a small biotite-monzogranite nunatak in the Northern Foothills region, Northern Victoria Land, Antarctica. The grooves, similar in appearance to the ‘rinnenkarren’ described in the karst literature, are developed on steeply inclined (>35°) bedrock surfaces while the rock varnish occu...

The aim of the present study was to compare the recolonization pattern of mutans streptococci on densely colonized teeth with and without fixed orthodontic appliances after treatment with a 40 per cent chlorhexidine (CHX) varnish (EC 40, Explore). Healthy subjects free of carious lesions requiring fixed orthodontic appliance treatment but with high bacterial mutans streptococci saliva counts we...

The present investigation was undertaken to determine whether cavity varnish can serve as a bacterial reservoir. Twenty-eight samples of cavity varnish were collected From bottles in use in a clinic and two From previously unopened bottles of the material. Samples were grown on a variety of media, both aerobically and anaerobically. Results indicated growth in 25 of 30 samples. The two Freshly ...

We investigated the rock art (petroglyphs) in Al-Quwaiyah Governorate (Saudi Arabia) with focus on Musayqira site. Iconographic analysis showed a broad variety of human depictions, game animals (ibex, ass, ostrich, lion, etc.), domestic (cattle, camel, horse, dog, inscriptions and abstract symbols. Archaeometric measurements by pXRF provided areal densities Mn petroglyphs intact varnish. Varnis...
