cephalometric measurement of "L1-apo distance" in a Pakistani sample

ABSTRACT

Knowledge of the normal dentofacial patterns of various ethnic groups is important for clinical and research purposes. The objective of this study was to measure the norm for the "L1-APo distance" in a hospital based Pakistani sample. The obtained data was also compared with the already existing White American mean of the "L1-APo distance". It was a descriptive cross sectional study which was carried out in KRL Hospital; Islamabad.100 lateral cephalometric radiographs [50 females and 50 males] were obtained and traced for the above mentioned measurement. The database was developed in SPSS 10.0 for windows. Results showed that subjects in the present sample have more labial inclination of the lower incisors over the basal bone as compared to the White Americans. [p value .00] And the females of the sample have slightly more labial inclination as compared to the males although this difference is not significant. [p value .083]
