Abstract: The study was conducted to assess the distribution, prevalence, severity of malocclusion and orthodontic treatment need in Baghdad governorate in relation to gender and residency, and whether it has increased or not over 12 years by comparison with previous survey in Baghdad.A multi - stage stratified sampling technique was used in this investigation to make the sample a representative of target population. The sample consisted of 2700 (1349 males and 1351 females) intermediate school students aged 13 years representing 3% of the total target population.A questionnaire was used to determine the perception of occlusion and orthodontic treatment demand of the students and the assessment procedures for occlusal features by direct intraoral measurement using veriner and an instrument to measure the rotated and displaced teeth. In summary the followingresults were obtained : 1 - 7.7% of the sample had some type of orthodontic treatment or consultation.2 - 39.1% of the students answered that they have malaligned teeth, being significantly more in female than males.3 - of the students who stated that they have malaligned teeth, 26% reported that they had crowded teeth, 26.6% had spaced teeth, 22.4% had protruded teeth and 25.7% had rotated and displaced teeth.4 - Regarding the answers of the effect of mal - aligned teeth, 70.3% answered that it affects their appearance, 17.7% chewing, and 7.7% speech while 4.1% answered that mal - aligned teeth did not affect appearance, chewing or speech.5 - the most common reasons for not seeking orthodontic treatment that the student thought that treatment is fear of pain (48.8%) and not important or not possible (25.8%).6 - One or more missing teeth due to extraction or trauma were found in 4.9% of the sample, and the most common extracted teeth were the first molars (1.6% mandibular and 0.9% maxillary). One or more rotated teeth were found in 38.3% of the sample; one or more displacement teeth were found in 19.6% of the sample.7 - The maxillary anterior region showed the highest prevalence of 2mm or more spacing (15.2%) and the mandibular anterior region showed the highest prevalence of 2mm or more crowding (12.6%); a maxillary central diastema of 1mm or more was found in 18.1% of the sample with a mean of 0.306±0.015mm.8 - Angle’s class I occlusion was found in 78.29%of the sample, class II in 19.5% (17.2% division 1 and 2.3% division 2) and 2.3% had class malocclusion (1.6% postural and 0.7% true). The mean overjet of the sample was 3.31± 0.04 mm. The mean overbite was 2.99±0.03 mm,9 - Midline shift (?1mm) was found in 54.3% of the sample (28% to the right and 26.3% to the left side).Soft tissue impingement was found in 3.3% (3% palatally and 0.3% labially). Normal lip form was found in 86.6%, contracting lip form in 10.1% and lip trap in 3.3% of the sample.10 - The DAI scores registered in this study ranged between 13 and 65 with a mean of 23.234±0.12. 7.3% with treatment highly desirable, and 4.5% with treatment mandatory.Significant changes in the proportions of malocclusions as a whole in school children were found over the last decade; also increase the need for orthodontic treatment among adolescents in the Baghdad commune and low perception level of the Baghdadi children to their own occlusion and the demand on treatment was remarkably low. This data will be useful for public oral health service and emphasize the need for orthodontic treatment among adolescents in Baghdad and stressing on the role of oral health education to encourage the children to undergo orthodontic treatment.

Abstract: The size of the nasopharyngeal airway was believed to have an important role in the development of the dentofacial structure. Therefore, this study was done on 60 subjects (30 males and 30 females) at age range 18 - 25 years. Cephalometric radiograph has been taken to each subject and the measurements were recorded. The sample was divided into two groups, class I skeletal relationship (15 males and 15 females) and class II skeletal relationship (15 males and 15 females). Comparisons between the different study groups were undertaken and the following results were obtained.In class I skeletal relationship, all the nasopharyngeal liner measurements and all the dento - cranium linear measurements are significantly higher in males than females, except lower airway thickness (PNS - ad1) and upper airway thickness (PNS - ad2)showed no significant gender difference. While all the angular measurements showed no significant gender difference.In class II skeletal relationship, most of the nasopharyngeal liner measurements have no significant gender difference, while all the dento - cranium linear measurements are significantly higher in males than females. In comparison for class difference between class I and class II skeletal relations in total sample, all the nasopharyngeal linear measurements have no significant class difference, except lower airway thickness showed significant difference which were higher in class II than class I and upper airway thickness showed significant difference which were higher in class I than class In the whole sample of the study, positive correlation was found between lower airway thickness and upper airway thickness.

Abstract: Elastomeric chains are one of the most commonly used force delivery systems. They have the ability to exert an interrupted force, convenience of use, compatibility to oral environment and cost effectiveness despite of the inherited disadvantage which is force degradation.This in vitro study was designed to evaluate the effect of alcohol presence in mouthwashes on force degradation of different configurations of clear elastomeric chains from Ortho Technology company which are : closed, short and long under the effect of time at different intervals (Initial, 1day, 1, 2, 3 and 4 weeks) with exposure to different chemical solutions.A total of (540) elastomeric chains of three different types (long, short and closed) transparent in color, with an initial length (19mm) and about 50% extension (29mm) were used for the study. These elastomeric chains was divided into four groups and exposed to different chemical solutions (Distilled water, Listerine Original alcoholic mouthwash, Listerine Zero alcohol mouth wash, Ethanol 26.9%) twice daily for 60 seconds each according to manufacturer's instructions to measure the amount of force degradation in different time intervals. These elastomeric chains were incubated in covered glass containers at 37C? for the entire testing period.The results of the present study showed that the elastomeric chains were greatly affected by time, the majority of force loss occurred after the first 24hr. then followed by a less steep gradient for the rest of the working period.We can conclude that alcoholic mouth wash (Listerine Original) causes an increase in force degradation of all types of elastomeric chains while alcohol free mouth wash (Listerine Zero) causes less force degradation of all types of elastomeric chains, additionally closed configuration elastomeric chains has the least percentage of force degradation than other configurations of elastomeric chains.

Abstract: Maxillary molar distalization is an important method for correcting class II molar relationship.The important thing in the use the distalizing appliances is to reduce the patient cooperation with minimizing the effects of distalizing appliances on the anchoring teeth.Aims : The aim of this study is to compare three different intra - maxillary molar distalization devices with different designs , force direction. Other aims are to compare the effect of these devices on first permanent molars in mesiodistal , buccopalatal, rotational aspects. It aims also to compare the effect of these devices on the first premolar ( which is a part of anchoring system ).Materials and Methods : The samples consisted of three groups; Frog appliance, K - Loop spring and Multidistalizing arch on typodont simulation system (Ormaco). Upper typodont arch of class II division I was used.Pre and postoperative digital images were taken and analysed using AutoCAD software for each group, Six parameters was measured and compared ; first molar ( vertical change ,tipping change ,rotation, distalization rate) and first premolar (vertical change ,tipping change).A significant value of 0.05 was determined.Results : The results of present study showed that the multidistalizing arch gave rise a significant distal tipping, extrusion, distopalatal rotation of first molar and gave rise the highest mean value of first molar distalization rate. Also, gave rise a significant distal tipping and extrusion of first premolar.Frog appliance showed the lowest mean value of molar distalization rate ,distal tipping and rotation , in comparison with Multidistalizing arch (MDA) and K - Loop spring. Also, these parameters ranged between the highest and lowest mean value in extrusion of first molar , first premolar vertical change , Also showed lowest mean of distal tipping of first premolar than Multidistalizing arch (MDA).K - Loop spring ranged between the highest and lowest mean value distalization rate , distal tipping of first molar. Also, showed the lowest mean value in extrusion of first molar and extrusion of first premolar and rotation of first molar.However, The K - Loop spring show mesial tipping of first premolar in comparisom with (MDA) and Frog appliance that show distal tipping of first premolar.Conclusions : It is concluded that the three methods are effective in molar distalization. The best method of first molar distalization ranged between the K - Loop spring and Frog appliance. Consequently the two methods showed good amount of molar distalization with minimal effects on first molar and first premolar.
