the dmf index of 2000 school children (1000 boys, 1000 girls) 10 to 15 years old is reported. cases were selected randomly among the school children of different schools, situated in various economic zones of isfahan city. almost 50000 permanent teeth have been examined for healthy, decayed (d), missed (m), and filled (f), and recorded as the dmf index. the mean dmf index of boys and girls unde...
The study was performed in 1997 and involved school children between the age of 6 and 12 in Novi Travnik, Bosnia and Herzegovina (n = 203) and Zabok, Croatia (n = 132). OHI-S (Simplified Oral Hygiene Index by Green-Vermillion) and DMF (Decayed, Missing, Filled) index were used as main outcome measures. Prewar data were taken from the respective literature. The value of the DMF/dmf (PERMANENT/de...
introduction: permanent first molar is the most important unit in the chewing system. ear-ly loss of first molars can significantly reduce chewing efficiency, increase overbite, lead to premature eruption of the permanent second and third molars, and displacement of adjacent teeth. the purpose of this study was to determine the associated factors of permanent first molar caries in 7-9 years old...
background: one of the most important health problems in life is dental caries or tooth decay. untreated caries are painful and may affect diet, school attendance, and sleep. tooth decay can also have significant negative health and social consequences in later life. objectives: the aim of this study was to determine the decayed, missing, filled teeth (dmft) index in 8-12 year old students in z...
The aim of this paper was to determine certain regularities in caries incidence in children in primary and permanent dentition in respect of clinical and non-clinical variables that can be collected in everyday dental practice. This way it could be easier for the operator to adjust individual preventive therapy of patients. The study was conducted on 301 subjects, aged 3-6 (74 subjects) and 11-...
Background The Decayed, Missing, Filled (DMF) index is one of the most common techniques for investigating dental decay. In recent years, the new International Caries Detection and Assessment System (ICDAS) technique has been introduced to the world as a standard tool to confront the present challenges in diagnosing dental decay. The present study aimed to investigate the reliability and repr...
OBJECTIVES The aims of this cross-sectional study were to evaluate the level of fear of dental procedures among schoolchildren and assess the relationship between caries experience and fear of dental procedures. SUBJECTS AND METHODS 275 children aged 7-11 years were recruited for the study. Before conducting a dental examination, each subject was asked to independently complete a Children's F...
The condensation of 2-aminoindole-3-carbonitriles and their 3-aminoindole-2-carbonitrile isomers with various DMF-dialkoxyacetals was investigated under microwaves. The appearance of reactive and versatile alkoxyiminium species allowed convenient access to indole precursors of building blocks with potential biological activity. The experimental results have been rationalised using DFT calculati...
We found that addition of N,N-dimethylformamide (DMF) induces phase separation of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP)-water mixtures. The phase diagram of a DMF-HFIP-water ternary system at 298 K showed that phase separation occurs in a closed-loop area in the water-rich mole fraction range of x(H(2)O) > ∼0.4. To clarify the mechanism of DMF-induced phase separation of DMF-HFIP-water mixtu...
