Background: Early diagnosis of abnormal habits may allow both dentists and parents to discourage these habits and avoid negative consequences. Aim: The present study was undertaken to assess the prevalence of oral habits in 6 to 11 year old children in Rajnandgaon city, Chhattisgarh, India. Methods: A total of 1891 school children aged 6 to 11 years from the city of Rajnandgaon reporting to the department of pedodontics were selected for the study. A thorough history was obtained on a specially designed proforma and presence or absence of oral habits like thumb/finger sucking, tongue thrusting, mouth breathing, lip biting, nail biting and bruxism were recorded. Data was analysed using chi-square test. Results: Prevalence of oral habits was found to be 33.2% in the total sample studied. Tongue thrust was the most prevalent habit affecting 17.4% of children, whereas 13% of children had mouth breathing habit followed by 1.7% of children with thumb/finger sucking. Prevalence of lip biting, nail biting and bruxism was found to be 0.4%, 0.3% and 0.4% respectively. Age and prevalence of thumb/finger sucking, tongue thrusting and mouth breathing were found to be statistically highly significant (p<0.001). No significant differences were found in any oral habits between boys and girls. Conclusions: Oral habits, especially if they persist beyond the preschool age, have been implicated as an important environmental etiological factor associated with the development of malocclusion. So, early diagnosis and proper treatment planning of these habits will reduce the occurrence of malocclusion.
