Cephalometric evaluation using Mcnamara analysis in a sample of Saudi adults.
J Pak Dent Assoc Jan ;14(2):76-83.

OBJECTIVE: The purpose of this study was to describe cephalometric norms of Saudi adults using McNamara`s analysis and to compare with the result obtained by McNamara. SUBJECTS AND METHODS: Cephalometric radiographs of 95 adults 45 males and 50 females, the mean ages were 28.4 years for males and 25.3 for females. All samples fulfilled the criteria of selection. Twelve points were digitized and processed by Dentofacial Planner® computer software program. Ten measurements, 8 linear and 2 angular were identified. For statistical evaluation, one sample t-test was performed. The mean values and the standard deviations for the cephalometric variables were obtained and the means were compared with McNamara study. RESULTS: Both Saudi males and females, have long lower anterior facial height, increased mandibular plane angle, and posterior positioned of the chin. The Saudi females have slightly increased mandibular length, slight prominence of midfacial length and maxillo-mandibular differential fall towards higher values. CONCLUSION: Dentally Saudi males showed protruded upper and lower incisors whereas the Saudi females showed protrusion in the lower incisors.
