ABSTRACT
Objective: This study was carried out to determine normal cephalometric values for the population i.e., Pathan descent presented at dental colleges of Peshawar, Pakistan.
Study Design: Prospective / cross-sectional study
Place and Duration of Study: This study was conducted at the carried out at dental colleges of Peshawar, Pakistan from Feb 2018 to Feb 2019.
Materials and Methods: Consecutive non-probability sampling technique was used foe selection of subject. Assessment of cephalometric parameters on standardized lateral cephalograms was done in 53 subjects (fulfilling inclusion criteria) aged 18-25 years with class I molars, canines and incisors relationship, straight profile, mild crowding and native Pashtuns. Data was analyzed using SPSS version 20.
Results: Twelve out of 16 (75%) parameters for subject population was significantly different from that of Caucasians’. A statistically significant increase was noticed in point A-Nasion-Point B angle, Witt’s Appraisal, Y-axis, posterior facial height/total anterior facial height percentage, Upper incisor-sella nasion angle and lower incisors-mandibular plane angle whereas statistically considerate decrease was noticed in thegonial angle, lower anterior facial height/total anterior facial height percentage, inter incisal angle, upper lip-e line distance, naso-labial angle and lower lip-e line distance.
Conclusion: Cephalometric normal values determined for the population presented at Dental Colleges of Peshawar had 75% of parameters significantly different from that of Caucasians’. This behooves an orthodontist to consider cephalometric norms specific to the Pashtun race when deciding between extraction and non-extractions therapies with/without orthogenetic surgery.
