• A custom made examination chart (Appendix 1) will be filled for each child including date, name, age, address, gender, medical history and any previous dental treatment. Parents' data includes: level of education and oral hygiene level.
• Prior to performing dental examination, the child will be asked to rinse his mouth with tap water and the teeth will be cleaned with cotton.
• The examiner will carefully inspect all surfaces of the teeth.
• All the primary teeth will be evaluated using CAST index as shown in Table 1.
• Each child will be given two printed sheets translated into Arabic, of his diagnosed caries status, the oral hygiene measures needed to inform the parents about the oral health status and how to keep good oral health and to indicate the need for treatment for children diagnosed with dental caries, and dietary bad habits that should be avoided to prevent caries occurrence.
