Aim:
The aim of this study is to determine the prevalence of dental caries in primary teeth among 4-6 years old school going children in the Namakkal District.
Materials And Methods:
The study covered a total of 850 school going children in a total of 26 schools in the Namakkal district of Tamil Nadu. The age group selected for this study ranged from 4 to 6 years of age. Each child was examined in their respective schools by one of the four calibrated examiners and decay, missing and filled teeth (dmft) index was recorded along with demographic details. This study was done in September-October 2013 in a span of 1 month duration.
Results:
Of 850 children examined, 560 (65.88%) children had dental caries. Mean dmft score was 2.86. Prevalence of dental caries was higher in boys (69.6%) than in girls (61.5%). The untreated decay teeth accounted for 92.4%.
Conclusion:
The prevalence of dental caries among 4-6 years old children is high in the Namakkal district. The need for the creation of dental awareness among children and their primary caregivers is crucial and the need for developing immediate oral health promotion strategies including an increase in school dental health programs is recommended.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
