Correlation between Bolton Ratio and Incisal Inclination

Aim: To investigate whether the bolton's ratio are correlated to the inclination of anterior teeth. Setting: Orthodontic department-de'Montmorency College of Dentistry, Pakistan. Methods: The cross-sectional study was conducted at Orthodontic department-de'Montmorency College of Dentistry, Pakistan.
