Introduction: 

Nasolabial angle is composed of two components: a) upper and b) lower component. Various foreign authors have developed different methods for evaluating this but consistent and reproducible methods for Indian population are few. Therefore, this should be placed within acceptable limits by planning treatment procedures accordingly to get the best aesthetic profile result and patient satisfaction.

Aim of the study:

To evaluate upper and lower components of nasolabial angle in different malocclusions in Bhopal population.

Material and methods:

It is a retrospective study, of sample size 150 that comprised of 60 profile pictures of individuals who belonged to Bhopal, out of which 30 were selected as aesthetically pleasing. Their lateral cephalograms were taken and traced. The study also used 120 lateral cephalograms of different malocclusions. The recorded data was analyzed using one-way ANOVA Test.

Result:

Significant results with p value<0.001 were found for the nasolabial angle among ideal group, Class I bimaxillary protrusion, Class II Division 1 and Class II Division 2, Class I crowding.

Conclusion:

Nasolabial angle is correlated with the type of malocclusion and the soft tissue variables also alter this angle.
