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 at
11 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.

Aims: To reveal the changes of the soft tissue profile of the nose, that include; length, height and depth
of the nose among four age groups. Materials and Methods: The studying sample subjects included
48, 41, 50 and 44 individuals of age 11, 12, 13 and 14 years respectively. The subjects were Iraqi individuals
of class I normal occlusion, who live in center of Mosul City. All subjects were radiographed
with the lateral cephalometric films, these films were traced and drawing the linear parameters of the
nose, the tracing involve the length (N` – Prn), width (N – Sn) and depth (Prn – Prn`). The results were
subjected to the descriptive and variance analyses. Results: The results appeared in males the length of
the nose increase in dimension with no significant differences when compared among the four age
groups, whereas in females showed significant increase when compared the 11, 12 years with 13 years
and with 14 years age groups. While, the h weight of the nose (N`– Sn) appeared in males and females
significantly increase at 14 years age group when compared with other age groups. But significantly
increased at 12 years age group as compared with 11 years age group, in males only. Mean while, the
depth of the nose (Prn – Prn`) displayed significantly increase at age 14 years group when compared
with 11 and 12 years age groups for both sexes. The comparison between sexes for the nose parameters
demonstrated that the length, width and depth of the nose displayed significantly increase in males than
females at 11 years age group and no significantly differences at other age groups. Conclusions: The
conclusions of the study are that the nose have significantly increase between 11 and 14 years age
group in both sexes, the nasal profile parameters have insignificant difference in dimensions among 12,
13 and 14 years age groups.

The Mandibular Dimension Changes Among Four Age Groups

Al-Rafidain Dental Journal, Volume 7, Issue 3, Pages 108-112

Aims: the study was planned to assess the value of the change among four pubertal age groups of
Class l occlusion. Materials and Methods: The sample subjects were comprise of the flowing groups:
11yeas(23 males&25 females), 12years(19 males &22 females), 13years(22 males &28 females) and
14years(22 males &22 females). Each individual radiographed with cephalometric film. The cephalometric
films traced and the mandibular lengths ( Ar–Pog, & Go–Gn & Ar–Go) were measured. The
data subjected to the descriptive and variance statistics at 0.05 significant level. Results: The findings
disclosed that the mandibular lengths (Ar–Pog, Go–Gn &Ar–Go) were significantly greater value at
14years age group as compared with 11,12,&13 years age groups. The sex variation appeared insignificant
change among the four age groups for the mandibular lengths. Conclusion: The increase mandibular
length at age 14 years can be regarded in relive the crowding at 11,12, &13 years age groups
for both sexes

Facial soft tissue convexity changes

Al-Rafidain Dental Journal, Volume 7, Issue 1, Pages 88-95
DOI: 10.33899/rden.2006.40055

Aims: To find the soft tissue changes of the total facial convexity, facial convexity and nasolabial convexity among four age groups. Materials and Methods: The studying sample subjects included 48, 41, 50 and 44 individuals of age 11, 12, 13 and 14 years respectively. The subjects were Iraqi individ-uals of class I normal occlusion, who lived in center of Mosul City. All subjects were radiographed with lateral cephalometric films, these films were traced, the tracing included the total facial convexity (Gl–Prn–Pgs angle), facial convexity (Gl–Sn–Pgs angle) and nasolabial convexity (Cm–Sn–Ls angle). Results: Displayed that the total facial convexity angle in both sexes appeared that no significant change among the four age groups, the facial convexity appeared insignificant differences among the four age groups in males, while in females showed significant increase between the 14 years age group as compared with 11 years age groups, and the nasolabial convexity demonstrated no significant changes among the four age groups for males, whereas in females showed no significant di-fference between 11 and 12 years age group and between 13 and 14 years groups, meanwhile, the 13 and 14 years age group explained significant decrease as compared with 11 and 12 years age groups. The sex variation showed the only significant increase in females than males at 11 years age group for the nasolabial angle. Whereas no significant change between males and females in all the angles at the 12 and 13 years age group. In 14 years age group, the facial convexity angle only showed a significant increase in females as compared with males. Conclusion: No significant change in total facial con-vexity, facial convexity and nasolabial convexity angles among the four age groups in males. Whereas, in females there were a significant increase at 14 years age group, than 11 years age groups for facial convexity and nasolabial convexity angles.
