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 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.

Abstract

Aims: To explore the upper lip thicknesses, height and it's relationship to the esthetic line. Materialsand Methods: The studying sample included 48, 41, 50 and 44 individuals of age 11, 12, 13 and 14years respectively. The subjects were Iraqi individuals of Class I normal occlusion, who live in centerof Mosul City. All subjects were radiographed with lateral cephalometric films, these films weretraced, the tracing included the upper lip thickness at skeletal points (A–A´ ), upper lip thickness atlabrale superius (Ls–Ls´), upper lip height at stromion superior to palatal plane and the upper liprelationship to the esthetic line. All these measurements were measured and then subjected to thestatistical analysis. Results: The results were demonstrated that the upper lip thickness (A–A`) and(Ls–Ls`) were only significant increase at 14 year age groups as compared with 11 years age group inmales. In female the upper lip thickness was only significant at 13 years group as compared with 11years age group, while the upper lip relationship to esthetic line showed only significantly greater valueat 14 years age group as compared with 13 years age group. Sex variation appeared a significantgreater value in male than female for the (Ls–E line) at 11 years age group, (A–A`) and (Ls–E line) at12 years age group, (Ls–Ls`) at 13 years age group and upper lip height at 14 years age group andupper lip height at 14 years age group. Conclusions: The soft tissue of upper lip profile parameterswere increased with increasing age group, and the upper lip significantly larger behind the esthetic linein female than male at 11, 12 and 14 years age groups.

Abstract

Background :Patients with β-thalassemia major (TM) require periodic blood transfusion and iron-chelating therapy for all their life and they frequently show complications like trace elements abnormalities.Objectives:To evaluate the levels of zinc, copper and magnesium in these patients and to study the relation of these elements with growth state.Methods:Fifty-four patients with TM, with mean age (15.4 years) and age range (7-31) years, and thirty healthy subjects as controls, their mean age (14.7 years) and age range (8-30 years) were included in this case –control study. Each group divided into children and adult groups. Serum levels of zinc, copper and magnesium of all groups were measured calorimetrically. Serum levels of ferritin were measured depending on ELFA technique, in addition to height and weight of all patients and subjects.Results:Mean serum levels of ferritin were significantly elevated in TM patients as compared to controls, while mean serum levels of zinc and magnesium of both patients groups were significantly decreased as compared with control subjects. Mean serum levels of both patients groups were significantly elevated compared to control subjects groups.Conclusion:Patients with TM were suffering from hypozincamia and hypomagnesmia and required additional adjustment, the patients also showed hypercupremia, and there was obvious growth defect in which may be a result of hypozincamia.Keywords:Thalassemia, zinc, height, short-stature

Abstract

AbstractIt is possible to determine heights of selective locations through terrestrial means by tying these locations to the sea level. Practical heights in geodesy, known as orthometric heights are referred to the geoid, which is approximated by the mean sea level (MSL).In the present study, A GPS and conventional leveling techniques were used to establish a network of (15) control points distributed inside Mosul University Campus, to be as a bench marks for the surveying applications which are very important and necessary for the civil engineering projects and the geophysical survey. The obtained results show that, there is an average variation between the orthometric heights measured by leveling instrument and the ellipsoidal heights measured by GPS, referred to as geoid undulation. ArcGIS9.1 software was applied in the study for the georeferencing process of the GPS measured dataset.Keywords: GPS, orthometric height, mean sea level

Abstract

The S2-complex drug is a chemical preparation of a low molecular weightsynthetic organometalic complex, and it has experimented in many researches to proveit’s activity in the treatment of the cancerous tumors, without any side effects. This drugis a potent immunomodulat or that stimulates both, the humoral a.nd cell mediated,immune responsesTo examine the effect of S2—complex administered locally and was designed totest the potential effectiveness of S2-complex in the management of periodontal disease.associated bone loss by radiographic evaluationThirty six pairs of similarly involved periodontal pockets in (20) patients agedbetween (30-50) years old with pocket depth more than 6 mm were selected. Split mouth,randomized study was carried out. Scaling and root planing was carried out in both sidesin test side received S2- complex for five days in a daily dose of O.l mm/kg injecteddeeply until reaching the bone of affected site, while the control side was received distalwater for 5 days in a daily dose of 0.l mm/kg injected in the same way as that for testside. S2 complex was infiltrated locally through the gingival tissue of the effected site.deeply until reach the defect bone using disposable insulin syringesClinical attachment level of gingiva were recorded at baseline and repeatedonce every 2 weeks. Periapical radiographs were taken for both test and control sides atbaseline and at the termination of the treatment after 2 months. A long the time of study,the patients put on a program of motivation to keep a good stander of oral hygieneClinical and radiographical parameters in general showed improvement with both test.and control groups, with a statical significant difference between themRadiographical evaluation showed high differences in hight and density of bone forboth groups, and effect to S2-complex was on sites of anterior and molar areas according, to the hight and density of boneThere was high improvement in the clinical attachment level from the base line in.control & test sides , there was higher difference between them
