Stomatologic examinations of 1370 children aged 7, 12, and 15, determination of hygienic indexes in them, and anonymous questionnaires distributed among 154 parents and 64 pupils, as well as study of the efficacies of fluorine lacquer and gel have lead the authors to a conclusion that the level of
The epidemiological studies of the severity and spread of caries of deciduous and permanent teeth in Moscow schoolchildren (n = > 20,000) aged 7-17 years in relation to the content of fluoride in the drinking water, to the use of fluorine-containing tablets and varnishes have provided evidence for
BACKGROUND
The purpose of this retrospective study was to compare fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) and ultrasonography (US) in the staging of patients with squamous cell carcinoma of the oral cavity.
METHODS
We compared preoperative evaluations
To investigate the effect of pit and fissure sealant combined with fluorine protective paint on prevention of children caries aged 5-8 years old.Convenience sampling method was used to select 120 children who received oral health care in the First The authors discuss the problem of fluorine load correction in caries. They claim that fluorine load of the body as regards caries prevention should never surpass the safe levels of total daily fluorine consumption. In children aged over 4 the safe level of total daily fluorine consumption is 2.5
Two experiments carried out with one hundred rats from the Osborne-Mendel-strain were supposed to prove the influence of selenium-containing-drinking-water on caries. The animals were divided into five experimental groups of twenty rats each. Selenium was tested in different doses as an addition to
Epidemiological survey of schoolchildren born and permanently living in Baku (fluorine concentration in drinking water 0.3-0.5 mg/liter) and in the Azizbekov region at a distance of 30-40 km from Baku (fluorine concentration at least 1.5 mg/liter) was carried out. The incidence of dental diseases
OBJECTIVE
To elucidate the points that require attention when interpreting fluorine-18-labelled fluoro-2-deoxy-d-glucose ((18)F-FDG)/positron emission tomography (PET) images by demonstration of (18)F-FDG accumulation in various areas of the oral cavity other than primary lesions in patients with
In this study, fluorine concentrations in drinking water and in urine of residents from a fluorine exposure area in China were tested. DMFT (average number of decayed, missing and filled teeth) of local residents in four age groups were also determined. The results of the study indicate that in
Fluorine as an essential trace element is necessary for life. The artificial increase of the natural fluoride-content of drinking water up to a maximum of one milligram per litre has been proved a prophylactic step against dental caries. The available material is examined to find out how far side
Examinations of the dental status of 12-year-old children of the same schools of the town of Baranovichi in various years of two decades, from 1970 to 1990, showed an increase in the incidence and intensity of dental caries up to the year 1986. After a program of caries prevention was introduced in
The most children caries morbidity was correlated with the intensity of carbohydrates uptake and was not directly connected with the fluorine content in the water. Author concluded, that the rational nourishment is significant in the caries prophylaxis.
We have utilized a noninvasive technique for measuring the partial pressure of oxygen (pO2) in alginate microcapsules implanted intraperitoneally (i.p,) in healthy non-human primates (NHPs). Average pO2 is important for determining if a transplant site and capsules with certain passive Classical epidemiological trials which were implemented in localities with a natural fluoride concentration in drinking water provided evidence that a concentration of 1 mg per 1 litre of water ensures on optimal preventive effect as regards dental caries and has no adverse effects on the health
Experimental and clinical investigations were performed to assess the caries-preventing potencies of hermetic covering with Epoxylite-9075 (USA) and vitacryl (USSR) insulating the intact fissures in molars and premolars. Intact sheathing is capable of protecting the tooth against caries for a long
