The present study was carried out on 252 children of 10-15 years old, reported to the out-patient Department of Pedodontics and Preventive Dentistry; of Teerthanker Mahaveer Dental College and Research Centre; Moradabad, in order to assess the relation between IQ of a child with dental caries and gingival disease. The statistical analysis was performed using Statistical Package for Social Sciences Version 15.0 statistical analysis software.

Statistically, there was a significant difference among different intelligence groups and the prevalence of moderate gingivitis (P < 0.001). Prevalence of caries was maximum among those with borderline intelligence (90.9%), and no significant association between level of intelligence and caries prevalence was observed (P = 0.572).

There was a statistical significant relation between IQ and prevalence of moderate gingivitis and no significant relationship was observed between IQ and dental caries.
