Evaluation of FH-SN angle in orthodontic patients.
Pak Oral Dental J Jan ;39(1):15-7.

As generally accepted mean value of FH-SN angle is 7°. Many previously done studies have shown that fluctuation in FN-SN plane angle exists that might be due to racial or geographic variations. Study was conducted in Nishtar Institute of Dentistry, Multan in February 2019. Lateral cephalogram of 114 orthodontic patients were drawn using 3H pencil and FH-SN plane angle was measured and documented. Lateral cephalogram were ordered into different growth patterns (class I, class II and class III) using wits value. Average FH- SN angle was 7.79º±2.38º. Greatest angle was found in Class III patients. There is significant difference among the different skeletal patterns according to ANOVA test. Average FH-SN angle among patients from Multan was 7.79°±2.38º. There is no significant difference among Class I, Class II and Class III orthodontic patients.
