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.
