Abstract

The purpose of this study was to investigate whether there is relationships between the skeletal craniofacial structures and the variability of facial profile. The sample consist of 100 cephalometric films [50 males & 50 females for adults (18-25years) having normal dental class I occlusion] collected from POP department, collage of dentistry in Mosul university. The sample classified according to skeletal classification into class I, II, & III also classified according to the profile into:- cisprofile,orthoprofile&transprofiles We measured the length of 3 skeletal bases, in addition to the position of pogonion& the thickness of soft tissue covering the anterior aspect of middle and lower face area. The variables entered spss computer system for analysis, we found that males have more skeletal CII & III than females, but females have more skeletal Cl II. males have larger records for all the variables & the difference is significant

Abstract

Aims: To determine the effect of an antioxidant agent on the tensile bond strength values of metal brackets bonded with to human enamel after bleaching. Materials and Methods: Thirty two sound human maxillary and mandibular premolars extracted for orthodontic reasons were collected. All teeth had undamaged buccal enamel, no caries and no pre-treatment with any chemicals. They were then stored in a solution of 0.1 % thymol before the experiment. Results: In the present study, we found that , tensile bond strength in group of direct bonding after bleaching was lower than other groups when compared with control group and the difference was significant at level p< 0.05 . The present investigation confirmed that waiting for a period of 7 days after bleaching is sufficient to obtain ade-quate tensile bond strength for clinical conditions. There was significant difference in tensile bond strength when the brackets that underwent direct bonding and ethanol with control group. No signifi-cant difference in tensile bond strength was observed when compared with the bracket immersed in a distilled water & with control bracket. Conclusions: In the present study we found that , tensile bond strength in group of direct bonding after bleaching were the lowest than other groups and when com-pared with the control group, the difference is significant. There was a significant difference in tensile bond strength when comparing the group that underwent direct bonding with control group.

Abstract

Aims: The purpose of this study was to determine the curve of Spee in class I and class II division 1 malocclusion groups to investigate whether there is a relationship between the depth of Curve of Spee with arch circumference and other variables (overjet and overbite) between two classes of occlusion. Materials and Methods: 60 dental casts of untreated adolescents, 30 girls and 30 boys aged 12–15 years, were obtained from secondary schools at Mosul City. The sample included 2 groups; the class I occlusion group and class II1 malocclusion group, each group comprised from 30 subjects (15 boys and 15 girls). The depth of curve of Spee and arch circumference were measured on mandibular dental casts. Overjet and overbite were assessed with a vernia. Description of the variables within each class and comparison of the variable between two classes were assessed by student t–test. In addition, a correla-tion coefficients between the depth of curve of Spee and other variables were calculated. Results: the results showed that there were no significant differences between genders within the groups for all va-riables. However, these variables showed sexual differences between two groups. Statistically signifi-cant correlation was also found between the depth of Spee and overbite, overjet and arch circumferences in both groups.

Abstract

Aims: To determine cephalometric standards for Iraqi adults using Holdaway soft tissue analysis. Materials and Methods: The sample comprised 60 individual (31 males and 29 females), aged 18–23years. Ten linear and tow angular parameters were measured on lateral cephalometric radiographs, using the definitions provided by Holdaway. For each variable mean and SD were calculated, in additionindependent samples t– test was performed to detect sexual dimorphism. Results: Some differences were determined when the measurement obtained for Iraqi sample were compared to Holdaway norms.Iraqi adults showed a more obtuse H angle, less nose prominence, more upper lip strain, more skeletal convexity, and greater soft tissue chin thickness. In addition, a comparison between males and femalesrevealed a significant sexual dimorphism for upper lip sulcus depth, upper lip thickness, basic upper lip thickness, and soft tissue chin thickness. Conclusions: soft tissue cephalometric norms are specific foreach ethnic group. The normative data for Iraqi population should be used as a guide for diagnosis and planning of orthodontic treatment

Abstract

Aims: This study aimed to assess the relationship between upper and lower incisors and soft tissue fa-cial profile. Materials and methods: The sample included forty eight Iraqi adults (22 men, 26 women) with Class I normal occlusion. Seven soft tissue parameters and six skeletal and incisal parameters were measured on lateral cephalometric radiographs. The data were analyzed using independent sample t test and Pearson correlation analysis. Results: sexual dimorphism was reported only for soft tissue convexity angle and interlabial angle. The results also showed correlation between incisor parameters and soft tissue parameters. Lower incisor inclination showed negative correlation with soft tissue pro-file angle for male and total samples. While both upper and lower incisors positions showed positive correlation with upper lip/NP angle and soft tissue pogonion/NP distance. Positive correlation was no-ticed between interincisal angle and soft tissue profile convexity angle for the total sample. Conclu-sions: upper and lower incisors are correlated to the overlying soft tissue structures. This correlation was mostly significant for the upper lip vermilion, upper lip base and tip of the nose.

Abstract

The aim of this study was to provide an additional information about occlusal variations, and to determine the possible sex difference in a group of young Iraqi who were seeking for orthodontic treatment.A sample of (253) orthodontically treated patients (125 female and 128 male) selected from (3719) patients attending P.O.P department in college of dentistry in Mosul University, for each one the age, sex, molar occlusion in accompanied to some selected malocclusion criteria (crowding, spacing, crossbite and openbite) were recorded. The results of this research evaluated the number, percentage for each type of molar occlusion and the malocclusion criteria. The using of two sided Z-test of twoproportions at (p<0.05) indicate that significant sex difference in CL IIb, CL II1,crowding and spacing and a non-significant difference in CL Ib, CLIu, CL II, CL II2, CL III, CLIV, crossbite and openbite. The occlusal variation for Iraqi follows a universal general distributional pattern for most world populations.

Abstract

This study was carried out to assess the occlusal features in two Iraqi rural populations, to evaluate the prevalence of these criteria, to explore the difference in these features between the two communities and to provide data base for the malocclusion add to the available informations mainly in rural areas. A sample of(268) males with age range(12-18) years(139 persons from Al-Sharkhan and 129 from Al-Shamsiat rural areas. The statistical analysis revealed that the normal occlusion form(38%) for the two areas while the Class I malocclusion appeared in(54.1%) of the total sample, but Class II division 1 and 2 occurred in(8.2%),(2.2%) respectively, and lastly the Class III malocclusion noticed at(6.3%). The most commonly occurring feature was the generalized dental spacing(40.31%) followed by the generalized crowding(23.25%), and deep bite of which the total overlapping of the lower anterior teeth was occur in(7.08%). Nevertheless, open bite noticed at(1.49%) of the total sample. In this research, there was only a significant difference between the samples of two rural areas at the generalized dental crowding, spacing and in the slight and extreme increase in over jet. Also the unilateral cross bite,buccally erupted canines were more common than the bilateral one.
