Background: Epidemiological studies of malocclusion not only help in orthodontic treatment planning and evaluation of dental health services but also offer a valid research tool for ascertaining the operation of distinct environmental and genetic factors in the etiology of malocclusion.

Aims: To assess the prevalence of malocclusion in 10-16 year old school children in four zones of Karnataka state. Settings and design: School settings and Descriptive cross-sectional survey.

Methods and material: A cross-sectional epidemiological survey was conducted in all the four zones of Karnataka. School children in the age group of 10-16 years were the target population. Population proportionate technique was employed for the sample size estimation. A total sample of 9505 was randomly selected from 102 schools all over Karnataka.

Statistical analysis used: Simple descriptive statistics were used to describe the study variables.

Results and conclusion: The prevalence of malocclusion seems to be equally distributed in all the four zones of Karnataka.
