[Show abstract][Hide abstract] ABSTRACT: The purpose of this study is to formulate cephalometric norms of the Saudi population; and to evaluate whether significant cephalometric differences exist between Saudi and Caucasian patients. Lateral cephalometric radiographs of 60 selected Saudis (30 males and 30 females) with esthetically pleasing and harmonious faces, Angle I molar relationship, with all permanent teeth present and no history of orthodontic treatment or facial trauma, age range between 20 and 30 years were analyzed using the Downs and Steiner analysis. The means, standard deviations, and ranges of the measurements were compared with the norms established by Downs and Steiner. Statistically, several significant differences were noticeable in the results of the present study when the cephalometric mean values for the selected Saudi population were compared with the norms suggested for a white Caucasian population by Downs and Steiner. The results of the present study are significant and showed normal Saudis have a slightly protrusive maxillae, a tendency to Class II facial pattern, and a high mandibular plane angle. These results have clinical implications in the diagnosis and treatment of adult Saudis with dentofacial deformities.

[Show abstract][Hide abstract] ABSTRACT: 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.

[Show abstract][Hide abstract] ABSTRACT: The purpose of the present study was to determine the mean and standard deviation of eruption for primary dentition in children from Saudi Arabia and to compare it with another sample of full-term children who are clinically healthy between the ages of 4-40 months. The results were significantly different from available literature on eruption patterns in children. Moreover, there is a slightly delayed eruption of primary teeth in Saudi children when compared to Caucasians. However, the order of eruption of primary teeth was the same as reported in other studies.

[Show abstract][Hide abstract] ABSTRACT: The objective of this study was to describe the craniofacial pattern of Saudi ethnic groups and to compare it with accepted standards for the caucasian population according to Steiner analysis.
Lateral cephalometric radiographs of 87 Saudi students (74 male and 13 females) with balanced harmonious faces and clinically acceptable permanent occlusion, aged 21-27 years old were used. A computer-aided cephalometric analysis was performed, and the mean values and standard deviations for the various cephalometric variables were obtained.
A comparison of the results with the Steiner standards showed that the Saudis have relatively similar skeletal relationship and dentally there was a tendency toward bimaxillary protrusion. Further, there was a decrease in the lower facial height.
It was evident that even in the Saudi ethnic groups with so-called well-balanced faces, there were some fundamental variations in the craniofacial structure of the Saudi Arab when compared with Steiner norms.
