Abstract

Background: The internally displaced children are vulnerable groups have less access to dental services, worse oral health, and bear a disproportionate burden of oral diseases.Aim of the study: This study was conducted on group of internally displaced children living in Baghdad governorate camps to measure their dental caries prevalence and experience and find out the association between dental caries and the duration of displacement in camps.Subjects and methods: A sample of 1393 children were selected, 567 internally displaced children from camps in Baghdad governorate and 826 school children as control matching in age and gender. The age of children ranged from 5-12 years old. Oral examination was performed using WHO 2013 criteria, to measure dental caries using CPI probe.Results: There were a significant difference of dmfs and dmft between Internally displaced children and Schoolchildren. Caries free Internally displaced children were 39.2% and 30% among school children. There was no statistically significant correlation between camp duration and dental caries experience in deciduous teeth while a significant relation was found in permanent teeth.Conclusion: This study revealed an increase in dental caries experience with increase in duration of displacement. Hence this survey highlighted the need of internally displaced children to dental health education programs and preventive measures and give information for monitoring the caries which is helpful for policy makers.

Abstract

Background/: Buccal tubes are orthodontic attachments used on the posterior teeth instead of bands, so it is important to focus on the effect of their properties on orthodontic treatment. The aims of the present in vitro study are to evaluate and compare the buccal tube front and back openings dimensions and the torsional play angle of six different brands.Materials and Methods: The samples consisted of Single bondable, non-convertible first molar buccal tubes from six brands supplied from six companies (Dentaurum, Forestadent, Ormco, 3M, American Orthodontic, A-Star). Regarding tube opening dimension, ten buccal tubes of each brand were examined by an optical microscope. Each tube was fixed during examination using synthetic mud and oriented for observation of the front and back slot openings. A picture was taken for both tube openings and the result appeared on the computer's screen where width and height measurements were made. While regarding torsional play angle, ten buccal tubes of each brand were used. Each tube was fixed on a metal block attached to a surveyor base. Then an L-shaped wire was inserted inside the front opening of the tube. Two photographs were taken, one with the wire in free fall position and the other with the wire elevated by a 10g weight with the same angle of shooting as the first photograph. Later, the two images were superimposed in Adobe Photoshop program, and an electronic MB-ruler Software was used to calculate the angle which represents the torsional play within each tube. The data were then statistically analyzed using ANOVA and LSD tests.Results: There are marked differences between measured tube dimensions and the manufacturer stated dimensions with the front tube openings being generally larger than the back opening dimensions. Furthermore, the torsional play angle was highest in A-Star and smallest in Ormco's tubes. This angle was significantly correlated to the height of the tube front opening.Conclusion: It can be concluded that tube dimension varies among different companies and effect greatly torsional play angle.

Abstract

Background: Cortical bone thickness is important for the stability of mini implants. Placing mini implants in sites of favorable cortical bone thickness would guarantee better initial stability and long-term success. The aim of this study was to investigate gender, side and jaw differences of the buccal cortical bone thickness as a guide for orthodontic mini screw placement.Materials and Methods: The sample was selected from the patients attending the Specialized Health Center in Al-Sadr City / 3D department. Thirty patients (15 males and 15 females) were selected and cone beam computerized tomographic images were done. Then the buccal cortical bone thickness was measured at thirteen inter radicular sites in the maxilla and mandible from the mesial side of the second molar to the mesial side of the second molar on the other side. The resulting data were statistically analyzed using independent t-test on SPSS program.Results: The buccal cortical bone thickness of the males was more than the females for both jaws. The mandibular buccal cortical bone thickness was thicker than in the maxillary and in the anterior region was thinner than in the posterior region for each jaw. The thickness of the buccal cortical bone was generally greater on the left side

Abstract

Background: With the increasing demand on esthetic orthodontic appliances, discoloration of clear elastomeric chainsand modules remains an issue which concerns both orthodontics and patients. This in vitro study was conducted toevaluate the effect of exposing stretched clear elastomeric chains from six different companies (Ortho Technology,Ormco, Ortho Organizer, American Orthodontics, Opal and G&H companies) to three types of dietary media (tea,coffee and turmeric).Materials and methods: A total of 960 lengths of six modules were cut from short type elastomeric chain; 160 piecesfrom each brand. The specimens were stretched 50%, placed on plastic boards, and incubated in water at 37°C for 1day, 7 days, 14 days and 28 days. Once a day, the specimens were immersed for ten minutes in the testing dietarymedia, washed and then returned back to the water container. Color measurements were made before and afterincubation of the specimens. Digital image were taken by an SLR digital camera and the color changes werecalculated according to CIE L*a*b* color space system by Adobe Photoshop program. The resulting data werestatistically analyzed using ANOVA and LSD tests.Result: Elastomeric chains from AO, Opal and G&H companies were the most brands prone to discoloration. OrthoOrganizers and Ortho Technology chains were the least prone to discoloration. Tea, coffee and turmeric solutionsdiscolored elastomeric chains from all companies in a variable degree, however turmeric caused significantly morediscoloration, followed by tea and least by coffee. The amount of discoloration caused by tea and coffee increasesgradually to peak at 28 days, while most of the discoloration caused by turmeric was in the first day and reached aplateau in a week.Conclusion: To decrease the discoloration of clear elastomeric chains the consumption of colored dietary mediaespecially spices like turmeric are to be discouraged

Abstract

Aim: This study aimed to compare different types of ligation methods to obtain maximum tooth movement with the least undesirable rotation.Methods: Titanium brackets bonded to acrylic canine teeth were ligated to straight stainless steel (SS) archwires using four ligation methods (figure-O and figure-8 elastics, SS ligatures, and Leone Slide ligatures). The teeth with the ligatures in place were stored in a water bath at 37ºC for 1 day, 1 week, 2, 4 or 6 weeks before testing. The teeth were retracted through softened wax along the archwire and the amount of tooth movement and degree of rotation were measured.Results: Slide ligatures showed the highest distance of tooth movement and degree of canine rotation followed by figure-O elastics, while figure-8 elastics showed the least amount of retraction and degree of rotation. SS ligatures showed moderate tooth movement with a minimal degree of rotation.Conclusions: The study recommends the use of loose SS ligatures for canine retraction in sliding mechanics, while Slide elastic ligatures are best used in leveling and aligning stage of crowded teeth since they showed reduced friction with the archwire
