Background: In orthodontic diagnosis and treatment planning assessment of an individual’s facial skeletal pattern in vertical, sagittal and transverse direction is prevalent. Dental compensation is the reverse of skeletal disharmony.
Objectives: This study has correlated the position of mandibular incisors inclination with different facial types and with the mandibular symphyseal morphology.
Materials and Methods: The sample consisted of 100 Pakistani patients of two different age groups i.e. adolescents up to 12 years and audlts up to 22 years on which R–angle, Li–MP, B–MP, Li–MP, symphyseal width (W) and depth (D) were measured.
Results: No correlation was found between Li–MP and R–angle, B–MP, Li–MP, and W except with the D i.e. symphyseal depth.
Conclusions: No significant association observed between lower incisor inclination, different facial types, and symphyseal morphology except with the depth of the symphysis. Slight correlation of differential jaw growth and dental changes with age are coincidental events with no relationship.
