for all age groups children having caries experience (Decayed, Missed, Filled/DMF. Although the incidence of other dental diseases such as erosion, traumatic injuries and fluorosis was found to be low among all age children but the still curative management and services should be provided to 18.6%, 54.5% and 18% respectively of children due to enamel discoloration or traumatic injuries. Therefore, a specific clinic should be available all through kingdom of Bahrain to serve those children, because those children if go throughout available community dental services then awaiting time will be very long to get appointment, and disease will be exacerbate; thus an attentive commencement of dental school based preventive programmes which is tugged from “Oral Health Promotion Strategy for age from birth to age 18 years old” is crucial; This reinforced by Petersen, 2003 cited by Varnne et al, 2006 “establishment of school based preventive programmes is attributed to the improvement of oral health in developed countries” Petersen, PE., (2003) cited by Varnne et al, (2006).
