The purpose of this study was to describe the morphology and measure the size of the sella turcica in Iraqi population and compared with available global data. Computed Tomography (CT) images of 71 individuals (49 males and 22 females) with an age range of 33.9 years were taken. Conventional measurements included three different heights of the sella turcica (anterior, posterior, median), its length, diameter and width, measured in relation to the Frankfort reference line (FH). In addition, the area of sella turcica was calculated. Morphometric methods were used to assess shape. Multiple statistical analyses were done to calculate differences in dimensions and to establish if any relationship exists between age, sex and the morphometry of the sella turcica. No significant differences in size of the sella were found between genders. When age was evaluated, all dimensions showed positive correlation with the age. Sella size of the older age group was as a rule larger than the younger age. The study found that sella turcica presented with a three different shapes: in a U shape (50.7 %), in a J shape (32.4 %) and shallow (16.9 %). Sella shape and dimensions reported in the current study can be used for discovering pathological enlargement of the pituitary fossa and may also be helpful in providing reference data in the orthodontic diagnosis, assessment and treatment plan and assessment of racial, gender and age specific variation in the Iraqi population.
The purpose of this study was to evaluate the dental arch relationship of non-syndromic Malay unilateral cleft lip and palate (UCLP) children and also assess the various congenital and postnatal treatment factors that affect dental arch relationship. Study models of 107 UCLP children were included in this study that was treated in Hospital Universiti Sains Malaysia over a period of 12 years (2000-2012). The mean age was 7.69± 2.46 (mean± SD). The dental arch relationship was assessed by GOSLON Yardstick which comprises five categories; named-1: excellent; 2: good; 3: fair; 4: poor; 5: very poor. All the subjects were divided into two groups; favorable (category ratings 1-3) and unfavorable (category ratings 4 and 5) groups. Kappa statistics was used to evaluate the intra-and inter-examiner agreements and logistic regression analysis was used to explore the responsible factors that affect dental arch relationship. The mean GOSLON score was 3.15±0.9. Total 72 subjects (68% of all subjects) were categorized into favourable group (category rating 1, 2 and 3) using GOSLON Yardstick. Intra-and inter-examiner agreements were good to very good. Palatoplasty and cheiloplasty seemed to be correlated with favourable dental arch relationship using crude regression analysis but no significant associations were found. This multivariate study shows no significant association between various congenital and postnatal treatment factors and dental arch relationship.
The aim of this study was to determine the most accurate position of the mental foramen in a sample of Bangladeshi dental patients. A retrospective study was performed using panoramic radiograph of 5923 patients, who ranged in age from 14 to 50 years old. All radiographs were obtained and analyzed for the most accurate position of the mental foramen by Planmeca Romexis
Abstact: The etiology of developing class III malocclusion and the role of craniofacial structures in this phenotype remain indistinct. The purpose of this study was to compare the relative relationship of craniofacial structures of DUSP6 gene mutation and non-mutation groups in class III malocclusion of Malaysian Malay families and their three generations. Thirty class III cephalometric radiographs of ten Malaysian Malay families including three generations with an average age 23, 54 and 79 years of each generation respectively were studied. All landmarks were positioned, determined and consequently tracings were completed Romexis software (Planmeca, Finland) to accomplish craniofacial morphology investigation. The statistical comparisons of the mutation and non-mutation group were conducted with independent t test and analysis of variance (ANOVA) was applied to evaluate the values for three generations in class III malocclusion among all measurements. The result of the current study revealed that in mutation group, there are significant differences in Co-Gn-B and SN-MDP variables compare to non-mutation group. However, almost all craniofacial variables show no significant differences among three generations. This study may suggest that in mutation group mandible is more deviated from cranial base compare to non-mutation group and there are virtually no skeletal changes among three generations with age in case of growing class III malocclusion.
The aim of this study was to analyze sagittal and vertical occlusal cephalometric analyses of Pancherz among Malaysian Malay and Malaysian Chinese. Further comparisons of each area of interest are needed to know the differences between them. It was a cross sectional study and total 640 lateral cephalogram (Malay=407, Chinese=233) were randomly selected among orthodontic patients. All sagittal and vertical occlusal cephalometric parameters of Pancherz were measured digitally using Planmeca software. Descriptive statistics, gender and racial dimorphism were analyzed using IBM SPSS Statistics Version 22.0. Data were analyzed using independent t-test. Statistically significant disparities were found in the Malaysian Malay population between males and females for 3 of 10 in the vertical occlusal analysis but there were no significant disparities found in sagittal occlusal analysis. In the Malaysian Chinese population, significant disparities found between males and females for 1 of 11 in sagittal occlusal analysis and 6 of 10 vertical occlusal analysis. Statistically significant disparities were also found between Malaysian Malay and Malaysian Chinese population for 10 of 11 parameters in sagittal occlusal analysis and 5 of 10 parameters in vertical occlusal analysis. In conclusion, there were significant disparities between Malaysian Malay and Malaysian Chinese in general and also between genders of each race seen using cephalometric analyses of Pancherz.
