Assessment of Intelligence Quotient using Raven's Coloured Progressive Matrices among school children of Hyderabad Karnataka region and its correlation with prevalence of dental caries.

Background: Intelligence is the ability of a mind to acquire knowledge and skills; gain for a fact; to take care of issues; to adjust to new circumstances; and one's ability for rationale, understanding, mindfulness, arranging, and imagination. In a general description, it is a capacity to recognize information and to employ it as knowledge toward a modified behavior within an environment. This thought helps children to maintain oral hygiene in a better way.

Materials and Methods: The present research was undertaken on 240 schoolgoing children aged 7-11 years of government schools of Hyderabad-Karnataka region, in order to estimate the relation between intelligence quotient (IQ) of a child with dental caries. IQ level has been assessed by using Raven's Colored Progressive Matrices as an IQ testing scale. Caries status was assessed by using Decayed, Missing, and Filled Teeth index.

Results: There was no statistical difference between children with different levels of IQ and dental caries. However, the majority of children who belong to Grade V (intellectually impaired) had higher dental caries.

Conclusion: An increase in IQ causes a decrease in dental caries and vice versa; however, no significant association was observed between the level of intelligence and caries (P = 0.202). There is a promising correlation between IQ and presence or absence of dental caries among children.
