Abstract

Aims: To reveal the possible soft tissue difference in the upper and lower lip heights, separations and coverage of lower lip to upper incisors in different Angle’s classes of malocclusion, to determine any difference in the mean between males and females for each variable and to find any correlation among the variables. Materials and Methods: Nightly nigh students (52 males, 47 females), 20–23 years of age that was randomly selected from the college of dentistry, University of Mosul.The overall sample was classified depending on Angle’s classification of malocclusion into four groups (Class I, II.1, II.2 and III). For each group, four facial soft tissue variables were measured directly using electronic digital viernier caliper. Results: A major findings that emerged from the research is that the Class I subjects possessed higher values of upper lip length followed by Class II then Class III, this difference is significant between Class I,III and II,III and non significant between I,II. Where as Class III subjects possessed non significant higher values of lower lip length followed by Class II then Class I. The lip separation value is non significantly higher in Class II subjects followed by Class III then Class I. While Class III subjects possessed non significant higher values of lower lip to incisor superior followed Class I then Class II. Conclusions: For each specific Angle’s class of malocclusion, a specific facial soft tissue parameters. The upper lip length is greater in Class I subjects. Class III subjects have the greater lower lip length. The inter–labial gap is larger in Class II subjects.While the coverage of the lower lip to incisor superior is greater in Class III subjects. Most of the variables are higher in males than females. Complex correlations among the studied variables are found that varied between weak to high positive or negative with varying degree of significance.

Abstract

The present study aimed to determine the mesiodistal axialangulations of upper and lower permanent anterior teeth inyoung Iraqi adults having normal occlusion using postero–anteriorcephalograph. Also to detect the sex difference in themesiodistal axial angulations of such teeth.The sample consisted of 33 young Iraqi adult students,17 males and 16 females aged 20–23 years old who were havingClass I normal occlusion. Postero–anterior cephalographwas taken for each subject and was traced to determine themesiodistal axial angulation of upper and lower permanentanterior teeth.The results revealed that the mean values of mesiodistalaxial teeth angulations in both sexes showed very limited variation.No significant bilateral differences were found for rightand left sides for both jaws (for males, females and totalsample).From the above results, it could be concluded that no significantbilateral differences in mesiodistal axial tooth angulationswere found for both jaws, for total sample and for bothsexes. Also, male–female comparison showed no significantdifference in mesiodistal axial teeth angulations and for bothjaws.

Abstract

The aim of this study was to evaluate the effect of orthodontic bands and metal brackets on the gingival health. The sample was composed of 15 randomly selected patients (5 males and 10 females) 11 to 17 years old. All patients were treated with edgewise fixed orthodontic appliances. Bands were cemented to upper and lower first molars and rest of teeth were bonded with composite. The teeth included in the study were upper right and lower left central incisors, and upper left and lower right first molars. The plaque index, the gingival index and pocket depths were used to measure the oral hygiene of the patients during six months period of fixed orthodontic treatment. The results indicated that orthodontic bands will provoke more periodontal changes than brackets.

Abstract

The present study was carried out to detect the possible effect of cranial base angulation on facial divergence in a sample of young Iraqi adults in Mosul City, to investigate the pattern of facial divergence of the sample and to reveal the sex difference in facial divergence.Sixty-four Iraqi adults (18-25 years),(32) males and (32) females, were collected according to certain criteria. Lateral cephalometric radiograph was taken for each subject. Eighteen variables were recorded and analyzed using SPSS system loaded on Pentium II computer.The results indicated that: 1) Flexure of basicranium has a detectable effect on facial divergence; 2) The most frequent facial pattern is posterior divergent with convex profile; and 3) There is a significant sex difference in facial divergence.

Abstract

Aims: To establish the interrelationships of linear measurements of the vertical facial heights among dif-ferent facial profiles in young Iraqi adult students. Materials and Methods: 75 students (48 males, 27females) of pleasing face, balanced facial profile were selected from the College of Dentistry, University of Mosul. For each subject seven vertical linear measurements{ Anterior facial height (n–gn), upper facial third, frontal third (tr–n ), middle facial third, nasal third (n–sn), lower facial third, gnathic third, (sn–gn), rest vertical dimension (RVD)(pn–pog), occlusal vertical dimension (OVD) (pn–pog) and angle of soft tissue profile facial convexity excluding the nose (n–sn–pog)} were measured directly on the subject’s face under standarized conditions keeping Frankfort plane parallel to floor, using electronic digital vernier cali-per (China). Results: sn–me, n–sn and free way space are significantly larger, while pn–pog (OVD) is sig-nificantly smaller in concave facial profiles (p≤ 0.05) indicating that the lower and middle facial thirds are responsible for the greater anterior facial height in these subjects compared with other facial profiles' sub-jects. The remaining variables distributed on statistical levels of difference between the upper and lower levels with non–significant difference (p>0.05) within facial profiles. Various correlations were noticed among all the studied variables for total sample, males and females and in different facial profiles. Of most important, is the positive significantly high correlation of pn–pog (OVD) and pn–pog (RVD) with n–me, sn–me for convex and straight profiles. Conclusions: From this study ,spatial relationships among various vertical facial dimensions and the dimensional proportions of different facial profiles in young Iraqi adult students were noticed.

Abstract

Most orthodontists and clinicians used to evaluate the patient's profile, clinically and radiologically. To obtain a correct diagnosis, most clinicians now realize the importance of an appraisal of the patient's facial esthetics from the frontal and lateral aspects.He aim of the present study is to establish the cephalometric mandibular norms of Iraq adults (18-25 years) by means of linear and angular analysis of PA and LAT cephalometric radiographs. The sample is collected from the students of Mosul University and is consisted of 100 Iraqi adults (50 males and 50 females) aged (18-25 years) with class one normal occlusion.LAT and PA cephalometric radiographs are taken for each subject, Twenty seven cephalometric measurements (11 angular and 16 linear measurement).Statistical analysis of data is done by using computerized statistical program Minitab. The angular measurements of the mandible showed that the females are significantly larger than males in the N.S.Ar, SN-MP, SN-Occ and B.Me-MP, where as the S.N.B., S.N.B., S.N.Pog and S.N.Id are significantly larger in the males, and the rest of the angular measurements show no significant difference between the two sexes. All the linear measurements of the mandible for males are significantly larger than the females

Abstract

Aims: To find the association between different Angle’s classes of malocclusion and to estimate the distribution of hypodontia according to gender, number of missing teeth and the site of the missing teeth. In addition, the heredity role in hypodontia was investigated. Materials and Methods: About 3415 subjects, 1750 females and 1665 males aging between 18–30 years were examined clinically in addition periapical radiographs were taken for each patient to exclude a possibility of impaction. A family history of hypodontia for each patient was taken (for father, mother, brothers and sisters). Then the sample was divided into 3 groups depending on Angle’s classification of malocclusion. Results: No clear association was found between Angle's classes and hypodontia, females showed higher prevalence of hypodontia than males. Family history was obvious in patients with hypodontia. The upper lateral incisor was the most frequent absent tooth. Conclusions: No association was found between Angle’s classification and hypodontia. The upper lateral incisor was the most frequent missing tooth. Maxilla was affected by hypodontia more than mandible. Females were affected more than males with very obvious effect of family history on hypodontia.

Abstract

The aim of the present study was to investigate whethereducated dental patients undergoing fixed orthodontic treatmentshowing better oral hygiene than dental patients who arenot educated.The sample is comprised of 16 orthodontic patients (3males and 13 females), 11–22 years old chosen randomly amongpatients at Department of Pedodontics, Orthodontics andPreventive Dentistry of College of Dentistry at Mosul University.The sample is divided equally into 2 groups; the first groupwas educated concerning fixed orthodontic treatment inrelation to oral hygiene and given education and instruction tokeep good oral hygiene during orthodontic treatment. Thesecond group is not educated. Swabs were taken from supra–gingival plaque of facial surface of upper right and lower leftcentral incisors, and upper left and lower right first molar teeth;one before orthodontic treatment and another (4–6 weeks)later and subjected to bacteriological investigation. Qualitativedata about oral microorganisms were collected and subjectedto statistical analysis.The results indicated that during treatment records forboth educated and non–educated groups show significant differencefor certain types of microorganisms and at differentlocations with the educated group scores the least in comparisonwith non–educated group
