Abstract: Orthodontic mini - implants are increasingly used in orthodontics and the bone density is a very important factor in stabilization and success of mini - implant.The aim of this study was to observe the relationship among maximum bite force; body mass index; face width, height; masseter muscle length, width and thickness; and bone density in an attempt to predict bone density from these variables to eliminate the need for CT scan which have a hazard on patient.Computed tomographic images were obtained for 70 patients (24 males and 46 females) with age range 18 - 30 years. The cortical and cancellous bone density was measured between maxillary and mandibular 2nd premolar and 1st molar at two levels from the alveolar crest (3 and 6 mm). Face height and width and masseter muscle length, width and thickness were measured from CT. Clinically; Maximum bite force was measured on first molar region unilaterally by a digital device. The sample was divided into two groups according to the body mass index into; normal and overweight.The results that were obtained showed that there were no significant differences in bone density or maximum bite force in both genders. Only the cortical bone density in maxilla in overweight group tended to be higher than normal body mass index group. The face width and height correlated significantly negatively with or maximum bite force which correlated significantly positively with cortical bone density and masseter muscle width.It was concluded that a prediction of cortical bone density of preselected areas can be made from maximum bite force, body mass index and inter - zygomatic width

Abstract: لقد ازدادت الحاجة الى استعمال الاجهزة التقويمية التجميلية في هذه الايام مما دفع مقومي الاسنان الى البدء باستخدام الاسلاك التجميلية والحاصرات التجميلية بالاضافة الى الاشرطة المطاطية التجميلية.الحاصرات التقويمية الشبيهة بلون الاسنان انتجت من انواع مختلفة م | The demand for better esthetic during orthodontic treatment has increased now a days, so orthodontists starting using esthetic arch wires, brackets and ligatures.Tooth colored brackets were introduced in different types of materials.Sapphire ceramic brackets are one type of esthetic brackets and their color stability remains the main concern for the clinicians and patients at the same time.The present study design to evaluate the effect of three different staining materials (black tea, pepsi and cigarette smoke) on the stainability of sapphire ceramic brackets bonded with three types of light cure orthodontic adhesives whichinclude : Resilience, Enlight and Transbond. The sample consisted of three hundred sixty sapphire brackets. The brackets were divided according to bonding materials into three groups each group consist of one hundred twenty brackets, then each subgroup further subdivided into four groups according to the material they were immersed (distilled water, black tea, Pepsi and cigarette smoke) with thirty brackets each, then each group with ten brackets further subdivided according to time interval of immersion in each media into three groups one day, seven days and fourteen days at 37°C in the incubator. A UV - Visible spectrophotometer (Shimadzu, UV - 1800) was used to perform a light absorption test.ANOVA and LSD tests were used to identify the significant effects of the staining materials at a significance level P ? 0.05.It was found that the immersion time gradually influenced the color stability of the adhesive materials with sapphire brackets with the highest activity observed at fourteen days interval. The brackets bonded with Resilience light cure adhesive are the most type affected by staining materials, then followed by the brackets bonded with Transbond and finally the brackets bonded with Enlight lightcure adhesive.For the staining materials it was found that the cigarette smoke is the mostpowerful staining material, followed by tea and finally pepsi.From the above result we can conclude that the type of adhesive must takein consideration when the esthetic brackets have been used.

Abstract: Bone density is a major factor that affect mini implant primarily stability. No Iraqi studies had been evaluated bone density related to mini - implant placement for orthodontic anchorage at age 13 - 15 years.The present research aims to evaluate gender, side and site differences in the bone density at various orthodontic implant sites for the maxillary alveolar bone (cortical; buccal and palatal and cancellous).The sample of this study consisted of CT images for patients who were attending Al. Shaheed Ghazi Al - Hariri Hospital/the Computerized Tomography department from January 2014 until May 2014. Twenty nine individuals (16 males and 13 females) had subjected to clinical examination, then 64 - multislice computed tomography scan data were evaluated and bone density was measured in Hounsfield unit at 21 points (9 points for each side and 3 points between the right and left central incisors).The results obtained showed that there were no significant differences in bone density between males and females and between the left and right sides. There are no significant differences in bone density between the maxillary buccal cortical bone and the palatal cortical bone except at lateral incisor and canine point where the palatal side had higher bone density than buccal side. The mean bone density of the cancellous bone in the anterior part was higher than that in the posterior of the maxilla.These differences in bone density between and within regions of the maxilla must be considered when placing mini implants and may provide valuable information when selecting sites, size, angle and placement methods for mini implant in the dental arch.

Abstract: The formation of white spot lesions around fixed orthodontic attachments is a common complication during and following fixed orthodontic treatment, which hinder the results of a successfully completed case.The aim of the study was to assess the effectiveness of the Caries Infiltrant (ICON®) on prevention of caries on the smooth enamel surface when applied alone or combined with conventional adhesives. To achieve this objective, seventy eight human premolar enamel discs were randomly assigned to six groups (n=13). The discs were etched and treated with resins of different monomer content forming the following groups : (1)Untreated etched samples served as the negative control, (2) ICON® (DMG), (3) Adper™ SB 2 (3M ESPE), (4) Heliobond (Ivoclar Vivadent), (5) ICON®+ Adper™ SB 2 and (6) ICON®+ Heliobond. Specimens were subjected to demineralization by immersion in hydrochloric acid (pH 2.6) for 18 days. Calcium dissolution into the acid was assessed by photometric test via spectrophotometer at 24 hour intervals.The results revealed that, there was a highly significant difference between the sealed groups and the unsealed (untreated) one (p?0.00) indicating that the unsealed specimens showed the highest amount of Ca ion loss among all other groups. Additionally, there was no significant difference between untreated specimens and the ICON® sealed ones. While, Heliobond decreased the Ca ion loss significantly compared to the untreated specimens and Adper™ SB 2 performed significantly better than both ICON® and Heliobond. Furthermore, the combination of ICON® with either Adper™ SB 2 or Heliobond served as the best protective measures and maintained the protective effect during the whole experiment period.Therefore, within the limitations of this in vitro study, it could be concluded that the use of low - viscosity Caries Infiltrant prior to application of the tested conventional adhesives increases their protective effect against demineralization.

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.
