Materials and Methods: The material of the present study consists of scintigraphic records taken from 17 early adult females treated with RME. All patients had a bilateral posterior crossbite, transverse maxillary deficiency, deep palatal vault, and dental crowding at the beginning of the treatment. The age range of the patients was 16.1 to 18.8 years, and the mean age was 17.3 Ϯ 0.86 years. Bone scintigraphy records were obtained before RME (T1), during the splitting of the midpalatal suture (T2), and after the end of active widening period (T3). Repeated measure analysis of variance was used to assess the differences between the periods. In addition, Bonferroni multiple comparison tests were applied to the measurements at which F values were found to be statistically significant. Results: According to the statistical analysis, significant activity changes were found in all regions studied and in all slices. The metabolic activity in all regions showed significant increases up to the separation of the midpalatal suture (T1-T2), whereas the metabolic activity exhibited a remarkable decrease (T2-T3) after the opening of the midpalatal suture. Conclusions: Scintigraphic records revealed an increase in the regions of interest scores during RME in all regions and all slices. Therefore, it can be speculated that RME has had not only dental effects but also skeletal effects on young adult patients.

Çalýþmada 3 cm uzunluðunda NiTi, paslanmaz çelik, çok sarýmlý paslanmaz çelik ve TMA ark telleri, alt sað 1.molar bandý ve premolar braketine ligatüre edilerek benzer þartlar altýnda 4, 5.5 ve 7'lik pH' larda hazýrlanan yapay tükürük içinde bekletilmiþtir. 30. 60. ve 90. günlerde alýnan yapay tükürük örnekleri atomik absorpsiyon spektrofotometre cihazýnda deðerlendirilmiþtir. Elde edilen veriler varyans ve çoklu karþýlaþtýrma analizleriyle karþýlaþtýrýlmýþtýr. Çalýþmanýn sonuçlarý, ark tellerinden en fazla iyon salýnýmýnýn pH 4 seviyesinde olduðunu, iyon salýnýmýnýn hýzýnýn üçüncü ayda en düþük düzeyde olduðu fakat salýnýmýn devam ettiðini göstermiþtir. Ni iyonlarý en fazla salýnýmý gösterirken en az salýným Cr elementinden olmuþtur.

Fixed orthodontic treatment was rendered following fan-type expansion of the maxilla. A Maryland bridge as a minimally invasive dentistry approach was used as a retention appliance and the patient's aesthetic appearance was restored.CitationBaydaş B, Denizoğlu S.

The null hypothesis tested was that there is shortened setting time of dental stones by using various different slurry water concentrations. Methodology In this study, two improved dental stones were used to fabricate master casts and dies. The tested fabrications were BegoStone (Bego Bremer, Goldschlägerei Wilh. Herbst GmbH and Co. Wilhelm Herbst-Strabe 1 D 28359 Bremen Germany), Moldano (Heraeus Kulzer GmbH and Co. KG Gruner Weg 11 D-63450 Hanau Germany) and plaster of paris (BMT, PK 121 Sivas, Turkey). Together with the manufacturer's values, the setting time and setting expansion amounts of the dental stone and plaster used in this study are shown in Table 1. Distilled water (Hinckley and Schmidt, Chicago, Ill. USA), tap water and slurry water prepared with the volume ratio of 16% and 2% were used as liquid for mixing the dental stone and plaster.

The material comprised lateral head films of 90 untreated subjects, 45 girls and 45 boys, aged 13-15 years. The radiographs were obtained in the natural head position using a fluid level method. The subjects were divided into three groups according to ANB angle: ANB angle between 1 and 5 degrees (skeletal Class I), larger than 5 degrees (skeletal Class II), and smaller than 1 degree (skeletal Class III). Each ANB group consisted of 30 subjects, 15 girls and 15 boys. Twenty-nine linear and four area measurements were used to assess cervicovertebral morphology. Differences between the ANB groups and between genders were assessed by means of analysis of variance and the least significant difference test. In addition, cephalometric measurements for all subjects were subjected to discriminant analysis. The results of the analysis of variance showed that there were statistically significant differences in the measurements of the lumen length of C1, inferior depths of C2 and C4, anterior intervertebral spaces of C2 and C3, posterior intervertebral space of C3, and anterior and posterior body heights of C4 among the ANB groups. The total length of C1, inferior depths of C2-C5, anterior intervertebral spaces of C2-C4, posterior intervertebral space of C2, anterior body heights of C4 and C5, and posterior body heights of C3-C5 demonstrated significant gender differences. The results of the discriminant analysis indicated that 54.4 per cent of the original grouped cases were correctly classified in the total sample. The final discriminant model was able to classify correctly 20 of the 30 Class I subjects (66.7 per cent), 17 of the 30 Class II subjects (56.7 per cent), and 12 of the 30 Class III subjects (40.0 per cent).
