ABSTRACT
As a result of application of acidulated phosphate gel with a dental floss on adjoining surfaces of primary molars it has been established that there has been significant fluoride intake as compared with the control group. It has been concluded that it is an efficient method of increasing fluoride content of the primary teeth.

The morphology and antigenic properties of 34 phages of Vibrio parahaemolyticus and V. alginolyticus strains isolated from Black Sea water, as well as their range of lytic activity and specificity of action, have been studied. Most of these phages have been found to lyze both V. parahaemolyticus and V. alginolyticus strains. In addition, highly specific phages capable of lyzing only V. parahaemolyticus serotype O5:K15, have been detected. The latter fact is a precedent indicating the possibility of search for other typing phages and the development of the scheme for the phage typing of V. parahaemolyticus in future.

The range of the lytic activity of 46 phages of parahemolytic vibrios isolated from lysogenic strains, sea water samples, crabs and mussels has been studied. The phages are represented by virions belonging to morphological groups II, IV, V according to the phage classification currently used in Russia and to different serological groups. No relationship between the sensitivity of vibrio strains to the phages under study and the specificity of serotypes O and K has been established. The preparation of diagnostic phage [see text] suitable for the identification of 82% of strains of parahemolytic vibrios has been proposed.

Dental services given to 4-15 years old patients who referred to Dentistry Faculty of Gazi University, Department of Pedodontics between 1985-1988 academic years, were evaluated. Classifications were done according to age, gender and type of dental services provided and the importance of preventive dentistry was indicated as a result.
