Cephalometric Evaluation using Mcnamara analysis in a sample of Saudi adults

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. 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 R 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. 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. Dentally Saudi males showed protruded upper and lower incisors whereas the Saudi females showed protrusion in the lower incisors

Facial esthetics in a selected Saudi population

The purpose of this study is to analyze the soft tissue cephalometric norms of the Saudi population and to evaluate whether significant cephalometric soft tissue differences exist between Saudi and Caucasian population. Lateral cephalometric radiographs of 40 selected Saudis with esthetically pleasing faces [20 males and 20 females]. The study was carried out in the College of Dentistry, King Saud University, Riyadh, Kingdom of Saudi Arabia between 1999 - 2001. The age range between 20 and 30 years was analyzed using Burstone system of soft tissue analysis. The means, standard deviations and ranges of the measurements were compared between males and females, and both figures correlated with the results obtained for a Caucasian population. Statistically, the facial convexity angle [glabella-subnasale-soft tissue pogonion] was found to be less convex for the Saudi group; the maxillary prognathism was more anterior, and the upper and lower lip positions were more anterior. The results of the present study are significant, and showed that the normal Saudis have a slightly lesser obtuse nasolabial angle, and a more anteriorly positioned upper and lower lips. These results have a clinical implication in the diagnosis and treatment of adult Saudis with dentofacial deformities

Orthodontic alternative in the treatment of congenitally missing lateral incisor

Missing maxillary lateral incisors due to congenital absence or loss as a result of an accident or pathologic condition present a problem which complicates orthodontic treatment. Two treatment procedures must be decided by the orthodontist, either to open spaces for the lateral incisor and use artificial teeth in these spaces or to contour the canines to resemble lateral incisors, and positioning them to function in place of the missing lateral Incisors. Placing well-shaped canines in positions by removal of pegshaped lateral Incisors is often an esthetic and functional improvement. The purpose of this paper is to describe the orthodontic treatment and reshaping maxillary canines to resemble and function as lateral incisors
