Abstract

Aims: To find out the changes among four age groups for total posterior facial height, upper anterior facial height and lower posterior facial height. Materials and Methods: The sample subjects were having normal class I molar relationships. The sample included: age 11 years (23 males and 25 females),age 12 years (19 males and 22 females), age 13 years (22 males and 28 females), and age 14 years (22 males and 22 females). All subjects were radiographed with lateral cephalometric films and the films were traced. The traced parameters of facial heights were measured. The results were subjected to the descriptive statistics and to the ANOVA And Duncan’s Multiple Range tests to detect the changes among the four age groups and to student's t–test to explore the sex variation fort these parameters.Results: The total posterior facial height displayed no significant change between 13 and 14 years groups, however, the values at both 13 and 14 years groups were significantly greater than that at11 year. The lower posterior facial height in males demonstrated a significantly higher value at 14 years group as compared to both 11 and 12 years groups, while females showed significantly higher value for both 13 and 14 years groups than 11 years group. The sex variation of the facial heights showed that males possessed significantly greater values than females for the lower anterior facial height at 11 years group, the changing also displayed significantly greater value for the total posterior facial heights at 14 years group. Conclusions: Both sexes tend to show an increase in the facial heights with the increase in the age groups and there are significant changes in facial heights between males and females except for total posterior facial height at 14 years age group.

Abstract

Aims: To compare the anterior and posterior facial heights among the sexes and total sample. Mean while; to find the facial height variations among the Class I, II and III dentoskeletal groups. Materialsand Methods: The sample comprised of 32 lateral cephalometric radiographs (16 for each sex) for each of the Class I, II and III dentoskeletal relationships. The age of the sample subjects was 15–20years. The lateral cephalometric radiographs were traced. The total, upper and lower anterior facial heights and the total, upper and lower posterior facial heights were measured. Results: No significantdifferences among the both sexes and total sample for the dentoskeletal groups were demonstrated. All the facial heights appeared significantly greater in Class II group than Class I group except upperanterior, upper posterior and lower posterior facial heights and was significantly higher than Class III group in upper anterior, lower anterior and upper posterior facial height. Class III group displayedsignificantly lower value in total facial height than Class I group and significantly larger value in lower posterior facial height than of Class I group and Class II group. Conclusion: The facial heights are notaffected by the sex variation, but there are certain variations in facial heights among the dentoskeletal groups.

Abstract

Aims: To investigate for any difference in facial height measurements between Iraqi Arabs and Kurds adolescents. Materials and Methods: lateral cephalometric radiographs Of 42Arabic adolescents in Mosul city and 43 Kurdish adolescents in Arbil city were assessed for anterior and posterior facial height measurements. Results: No significant difference was found in facial height measurements be-tween Arabic males and females. In Kurds, males showed significantly higher facial measurements than females. Kurdish adolescents had significantly greater facial height measurements than Arabic counterparts. Conclusions: Our results revealed that there is an overall difference in the facial height measurements between Arabic and Kurdish Iraqi adolescents

Abstract

The aims of this study are planned to evaluate the cranial base parameters of the short upper anterior facial height of open bite occlusion and compare them with the normal occlusion. Materials and Methods: The total sample of this study was 48 cases, divided into 12 case for each male and female of the normal class 1 molar occlusion and short upper facial height with open bite cases. The age of the patients was ranged between 13-15 years. A lateral cephalometric radiograph film was taken. All the cephalometric x-rays were analyzed to evaluate the cranial parameters and the upper anterior facial height. The data subjected to statistical analysis by using student t-test to distinguish the significant differences at 0.05 level for the short upper anterior facial height and to record the cranial parameters of the sample. Results: The comparison of the cranial parameters between the normal and open bite occlusions , the male expressed no significant difference ( at 0.05 level ) in the parameters except the liner (S-Ar) and the angular (N-S-Ba, N-S-Po and N-S-Co).While the female displayed no significant difference (at 0.05 level) in parameters except (N-S-Ba and N-S-Po angles). Conclusions: The short upper anterior facial height with anterior open bite case has influences on the cranial base development especially on (S-Ar, N-S-Ba, N-S-Po and N-S-Co)

Abstract

Aims: To evaluate the genders and over bite subjects group variation for the lower anterior facialheight (LAFH) and its component parameters in Iraqi population in Mosul City. Materials andMethods: The study was performed by using measurements on pretreatment cephalometric radiographsof 79 patients, 27 with normal over bite and 26 for each open and deep over bite. The age ranged from12–16 years with Class I dentoskeletal relationship. Results: The normal over bite group wassignificantly larger maxillary anterior alveolar ratio and the mandibular anterior and basal height inmale when compared with female. Deep bite group appeared significantly larger mandibular anterioralveolar depth in males than in females. The open bite group showed significantly larger interincisalangle in females than in males. Multiple range variation analysis of the lower facial height and itscomponent parameters disclosed no significant differences in these parameters among the over bitegroups except that the open bite group was significantly larger mean value in the LAFH andsignificantly lower mean value in the interincisal angle when compared with normal and deep bitegroups. Conclusion: The significant gender variation of the LAFH and its components of the normalover bite group were appeared in maxillary anterior alveolar depth, ratio and mandibular anterioralveolar height; whereas in deep bite group appeared in mandibular anterior alveolar depth, and in openbite group demonstrated in the interincisal angle.
