Abstract
Destruction of calcified tissue was caused by acids which are by product of carbohydrate metabolism of acidogenic bacteria consequent to dental caries. The purpose of this study was to assess the existence of acidogens potentially causing the dental caries and comparatively evaluation of efficacy of different toothpastes. The dental plaques of fifty persons belong to three age groups (1 - 20, 21 - 40, 41 - 60 year and above) were examined to identify microorganisms by the culture method. Thirty nine bacteria were isolated by spread plate method on BSMY I minimal media. Thirteen out of thirty nine, acidogens colonized in the dental plaques. Seven potentially acidogens CD17, CD26, CD27, CD28, CD29, CD34 and CD35 were treated with five different toothpastes. Inhibition effect of Triclosan and Fluoride containing tooth pastes were found more efficient. The results of the present study revealed that bacteria that commonly cause dental caries colonized in dental plaques of children and alcoholic person. Therefore, dental plaques must be considered a specific reservoir of colonization and subsequent dental caries. To reduce the dental problem triclosan and fluoride containing product should be recommended.

In present study we observed that the acidogenic bacteria mainly colonized in dental plaque cause dental caries
Summary
Dental caries is one of the most common chronic infectious diseases in the world [1,2]. Cariogenic bacteria interact by various recognized ways including co-aggregation [3], metabolic exchange, cellcell communication [4], and exchange of genetic material [5] These mechanisms benefit bacterial survival and can make dental biofilms difficult therapeutic targets in dental diseases. The burden of dental caries is still a major health problem in most industrialized countries as it affect 60% 90% of school-aged children and the vast majority of adult. This is largely due to the increasing consumption of sugar and inadequate exposure to fluorides [6]
