Objective: The purposes of this research were to establish cephalometric standards for Yemeni adults and to compare them with those of the Caucasians. Material and Methods: 100 Yemeni students (fifty males, mean age of 23.6 ± 2.1 years, and fifty female, mean age of 21.5 ± 3.1 years) with normal occlusions and wellbalanced faces were involved in the study. Inclusion criteria were a class I malocclusion with minor or no crowding, the whole teeth is present except third molars and no previous orthodontic, orthopedic or maxillofacial surgery treatment. Five angular and eighteen linear measurements were used for the skeletal, dental and soft tissue analysis. All participant’s lateral cephalometric radiographs were evaluated. The average values and standard deviations for all the angles and linear measurements were determined. The differences for each measurement between the Yemeni and Caucasian participants were calculated using unpaired t–tests. Results: Yemeni subjects had a more retrognathic mandibular positions (P< 0.05), protrusive mandibular incisors (P< 0.01), more protruded lip positions (P < 0.01), deeper mentolabial sulci (P< 0.01) and a steeper mandibular planes (P< 0.001) compared to the Caucasians. Yemeni females had a larger lower face height than Caucasian females (P< 0.001). Conclusions: The study provides specific standards for Yemeni adults and shows that the Yemenis had different skeletal and dentoalveolar cephalometric standards in comparison with Caucasians.   Keywords Cephalometric comparison; Skeletal and dental features; Yemeni norms.

ABSTRACT Objective: To study the longitudinal changes in 19 soft tissue cephalometric traits (according to the Bergman cephalometric soft tissue facial analysis). Materials and Methods: Cephalograms and photographs of 40 subjects (20 male, 20 female, from the Burlington Growth Centre) that were obtained at ages 6, 9, 12, 14, 16, and 18 years were used. Subjects were orthodontically untreated whites and had Class I dentoskeletal relationships (ideal overjet and overbite). Images were obtained with the lips in a relaxed position or lightly touching. Results: Three groups of soft tissue traits were identified: (1) traits that increased in size with growth (nasal projection, lower face height, chin projection, chin-throat length, upper and lower lip thickness, upper lip length, and lower lip–chin length); (2) traits that decreased in size with growth (interlabial gap and mandibular sulcus contour [only in females]); and (3) traits that remained relatively constant during growth (facial profile angle, nasolabial angle, lower face percentage, chin-throat/lower face height percentage, lower face–throat angle, upper incisor exposure, maxillary sulcus contour, and upper and lower lip protrusion). Conclusion: Current findings identify areas of growth and change in individuals with Class I skeletal and dental relationships with ideal overjet and overbite and should be considered during treatment planning of orthodontic and orthognathic patients.

The dental and skeletal dimensions of individuals with Class I skeletal pattern in puberty were compared. Eighty patients with Class I malocclusion were selected, independent of the vertical relations (overbite) of the incisors. The sample was divided into 3 groups: normal, short and excessive lower anterior face height, based on facial proportions. The dental and skeletal measurements of the 3 groups were compared among themselves. In the angular measurements, the results showed no correlation in the mandibular plane angle. In the linear measurements, the mandibular length was significantly greater in the group of patients with short lower anterior face height, with a positive correlation among the three groups. The dentoalveolar heights of the incisors had a positive correlation among the three groups in relation to the lower anterior face height, showing that they are responsible for its variation.

Introduction: Cephalometric norms of various populations show differences between diverse ethnic and racial groups. Thus, numbers of cephalometric norms have been established for different ethnic groups.Objective: To assess skeletal, dental and soft tissue features in a sample of well-balanced face of Sudanese university students.Materials & method: Lateral cephalographs were taken from 18-25 years old 35 male and 38 female Sudanese university students with balanced facial profile and Class I occlusion with no previous orthodontic treatment. Fourteen angular and five linear measurements, and facial index were recorded according to Husund analysis. Male and female mean values were compared statistically using Student t-test.Result: Statistically significant differences were noted between both genders especially in skeletal variables SNA˚, SNB˚, SNPg˚, ML- NSL˚, NL-NSL˚, UFH, LFH and dental variable I -Ī. Holdaway angle showed no significant difference between the genders. Skeletally, maxilla and mandible of the Sudanese sample were more prognathic compared to Caucasians and Arabs but less prognathic than the Africans. Dentally, maxillary and mandibular incisors were more proclined compared to Arabs and Caucasians. Soft tissue analysis showed more lip protrusion in Sudanese adults.Conclusion: The study offered normative cephalometric standards for Sudanese adults, which were specific for each gender group. The normative values showed that the Sudanese sample lied between African and Arab values which might suggest that the studied sample had an Afro-Arabian mixture.

Abstract The aim of our study was to compare soft tissue measurements with 3D imaging methods in individuals with untreated skeletal and pseudo-Class III malocclusions. The study sample consisted of 75 patients (38 males, 37 females, mean age 12.41 ± 2.35 years) with pseudo- and true skeletal Class III malocclusions and skeletal Class I malocclusions. Soft tissue evaluations of all patients were performed using 3D stereophotogrammetric facial images. In our study, 26 landmarks, 17 linear measurements, 13 angular measurements, and 5 volume measurements were made using the 3dMD Vultus software. The significance was determined to be p < 0.05 in ANOVA, Tukey tests. No significant differences were found among the groups in terms of demographic data (p > 0.05). The skeletal Class I control group had a significantly more extended upper lip and vermillion length as compared to the Class III groups. The soft tissue convexity angle and upper nasal angle were found to be wider in the Class III malocclusion group compared to those in the Class I control group. While the pseudo-Class III group had a significantly lower midface volume, chin volume was significantly higher in the skeletal class group. Upper lip volume was significantly higher in the Class I group. Using 3dMD for guiding clinicians in the differential soft and hard tissue diagnosis of pseudo-Class III malocclusions, differences were revealed in Class I patients in the middle part of the face. In the differential diagnosis of true Class III malocclusions, chin volume was found to be different from that of Class I patients.

The aim of this study has been to establish the values of soft tissue profile angles in subjects with dentoskeletal Class I, Class II Division 1, Class II Division 2, and Class III pattern, in order to examine the influence of sagittal dentoskeletal relation on the value of angular profile parameters. This comparative cephalometric study included the examination and the analysis by lateral cephalograms to evaluate soft tissue profile angles for 120 adult Caucasian subjects (60 women and 60 men) from the mid Balkan region divided into four groups towards ANB angle and incisors inclination. The following angles were examined: angle of facial convexity, facial convexity angle for the lower face and the angle of total facial convexity. By investigating the influence of the sagittal dentoskeletal pattern on the value of facial convexity angles, significant differences have been established between subjects with Class I and Class II Division 1 and 2 for all examined angles (p<0.001; p=0.011), while the differences between Class I and Class III are only significant for the facial convexity angle and facial convexity angle for the lower face, while the differences in the overall facial convexity angle are not significant (p=0.067). There are significant differences between subjects for all examined angles except the total facial convexity angle between Class I and Class III.

ABSTRACT Introduction The most commonly impacted tooth in the oral cavity is the mandibular third molar. Various etiologic factors have been suggested for impacted mandibular third molars. The pattern and prevalence of impacted mandibular third molars vary with different population and region. This study throws light on the prevalence and pattern of impacted mandibular third molars in Eritrea, East Africa. This is the first reported study regarding the same from Eritrea. Aim To assess the prevalence and pattern of impacted mandibular third molars in the population of Eritrea, East Africa by conducting a retrospective study from January 2009 to January 2014. Materials and methods This study was conducted in the Department of Oral and Maxillofacial Surgery, Orotta School of Medicine and Dental Medicine and the Orotta Referral Medical and Surgical Hospital, Asmara, Eritrea. A total of 1,813 clinical and radiographic records [orthopantomograms] were assessed and 276 cases were selected for the study as per the inclusion criteria. They were evaluated for the frequency among the various age groups, gender and region along with the sides affected, angulation and level of impaction. The presence of systemic conditions and associated pathologies was also assessed according to the type of impaction. Results The average age of these patients in the study was found to be 30 years, with the 20 to 30 years age group being the most affected (67.4%). Females (53.3%) were affected more than the males (46.7%). People from the Asmara region showed significantly more prevalence (79.7%) than the adjoining areas (20.3%). Mesioangular impaction was the most common angulation with a definite relationship to the age groups (p = 0.032). The level of impaction had no significant relationship to the age groups, gender, or region, although class I position A was found to be the most common type. Mesioangular class I position A impaction showed an apparent relationship with underlying systemic conditions, but it was statistically insignificant. Mesioangular impaction was found to be associated with the most number of pathologies (p = 0.001). Conclusion The prevalence of mandibular impaction was less in Eritrea (15.2%) compared with other populations. This study provides useful baseline data for the prevalence and pattern of mandibular impaction in the Eritrean population. Clinical significance This study throws light on the pattern, type, and frequency of mandibular impacted teeth as per age, sex, and region among the population of Eritrea.
