Introduction: Malocclusion is considered to be the third most prevalent oral pathology. Malocclusion can cause dental caries, periodontal diseases, aesthetic as well as functional problems. It can vary according to ethnicity, genetic, or environmental factors. There is a need to determine prevalence of malocclusion among different locations and ethnicities to help in determining the distribution of different malocclusion and planning awareness and interceptive programmes.

Objective: To determine the prevalence of malocclusion among individuals of Gandaki province based on Angle’s classification of malocclusion along with various occlusal traits. To compare malocclusion between male and female and between the two locations of Gandaki province.

Materials and Method: A cross-sectional descriptive study was conducted at villages Kobang-8 of Mustang and Namjung-9 of Gorkha from January to October of 2018. Molar relation, overjet, overbite, crossbite, rotation, spacing, and crowding were recorded. All data were collected by a single dentist and analysed with Microsoft Excel. The data collected were presented as frequency, percentage, mean, and standard deviations.

Result: Among total 190 participants, Angle’s Class I, II, and III were observed in 130 (68.42%), 18 (9.48%), and 42 (22.10%) respectively. Observed mean age was 30.69±13.75 years with 118 (62.11%) females and 140 (73.68%) Mongoloid forming the majority.

Conclusion: Class III malocclusion was seen to be more prevalent compared to other studies conducted in Nepal and abroad, which could be due to the ethnicity of the participants which was mostly Mongoloids.
