Öğe Dental age assessment the applicability of demirjian method in southwestern of eastern anatolia region Turkish children(Cumhuriyet Dental Journal, 2012) Karataş, Orhan Hakkı; Öztürk, Fırat; Dedeoğlu, Numan; Çolak, Cemil; Altun, OğuzhanObjectives: Age estimation plays an important role in forensic medicine and orthodontics. Many methods of age estimation have been suggested. Demirjian method is the most frequently used one of these. In the literature, there is a little known about applicability of this method in Turkish children. The aim of the present study was to evaluate the reliability of Demirjian method of dental age estimaiton and for description of mandibular permanent tooth formation in Turkish children from the southwest Eastern Anatolia region. Materials and Methods: A retrospective study was performed on 1015 panoramic radiographs and 5-15 years of age South western of Eastern Anatolia Regionof Turkish children. The stages of dental maturity of the mandibular left seven permanent teeth for each subject using the eight radiographic dental maturity stages demonstrated by Demirjian’s method were evaluated. A pired t-test was used for statistical analysis. Results: The mean difference between the chronological and dental ages ranged 0,28 to 1,10 years in boys and from 0,18 to 0,68 years in girls. South western of Eastern Anatolia Region of/Turkish children were generally delayed in dental maturity compared with children in Demirjian sample. The differences between the chronological and dental ages were statistically significant in 6-6.9, 8-8.9, 9-9.9, 10-10.9, 11-11.9 years in boys and in 8-8.9, 9-9.9,11-11.9 years in girls. Conclusions: Turkish children from the southwest Eastern Anatolia region are significantly more delayed in dental maturity compared to Demirjian’s French-Canadian sample. The applicability of Demirjian data is not suitable for Southwestern of Eastern Anatolia Region of Turkish children.Öğe Dental age assessment: The applicability of Demirjian method in southwestern of eastern Anatolia region Turkish children(2012) Karataş, Orhan H.; Öztürk, Fırat; Dedeoğlu, Numan; Altun, Oğuzhan; Çolak, CemilAbstract: Objectives: Age estimation plays an important role in forensic medicine and orthodontics.

For the DCT, wells of 96-microtitre plates were coated with each of three bonding adhesives. Eight uncoated wells, using identical inocula size, served as a positive control (bacteria with medium). A Strep tococcus mutans suspension was placed on the surface of each specimen that was held for 1 hour at 37C. Bacterial growth was monitored for 16 hours with a temperature-controlled microplate spectrophotometer. The kinetics of the growth in each well was recorded continuously at 650 nm in every 30 minutes. Three additional measurements were performed on these tested materials after aging for 1 week, 1 month and 3 months. One-way ANOVA and Tamhane s T2 multiple comparison tests were applied to the data. The level of significance was set as p<0.05. Results: The DCT showed that there were significant differences found in freshly mixed samples between four groups (p<0.001, F=20.901). Freshly mixed samples of Transbond Plus showed antibacterial activity (p<0.001). Kurasper F and Light Bond did not differ from positive control. In the measurements of aged specimens, all materials showed an increase in the logarithmic growth rate of Strep tococcus mutans. Conclusion: Only Transbond Plus showed antibacterial properties in freshly mixed specimens. However, none of the tested orthodontics composites showed antibacterial properties after aging.Öğe Ortodontik malokluzyonlar ve tedavilerinin havayolu boyutlarına, dil ve hyoid kemik konumuna etkisi(Cumhuriyet Dental Journal, 2014) Çağ, Betül; Öztürk, FıratÖz: Dil ve hyoid kemiğ in pozisyonu, bağ lı olduğ u kas ataçmanları itibariyle; havayolu boyutları da kendisini çevreleyen yapılar itibariyle maksilla ve mandibulanın iliş kisinden etkilenir.

The study comprised 832 Turkish children from the southwest Eastern Anatolia region aged 6–16 years based on radiological evidence from digital orthopantomograms. The mean age of the 832 patients was 11.03 1.98 years, with 424 males (mean age, 10.97 1.97) and 408 females (mean age, 11.09 2.00). The orthopantomograms were scored by two observers. The Wilcoxon matched-pairs signed-rank test used to assess intra- and inter-observer assessment revealed strong agreement between both observers’ measurements. Statistical analysis of the association between sex and age was performed with the Mann–Whitney U-test and the Wilcoxon test. Regression analysis was performed to obtain regression formulae for calculating the dental and the chronological age. The statistical analysis showed a strong correlation between age and third-molar development in males (R2 = 0.61) and females (R2 = 0.63). New equations (age = 7.49 + 0.69, development stage (DS) 38 + 0.70, DS18) were derived for estimation of the chronological age. The results showed that there was no significant difference in mineralisation between 18 and 28 and 38 and 48 in males or females. For both sexes, the dental age was lower than the chronological age. Males reached the developmental stages earlier than females. In the whole population, the boys’ and the girls’ dental ages were 0.84 years and 0.16 years earlier, respectively, than their chronological ages. The use of third-molar teeth as a developmental marker is suitable, particularly when comparing the obtained standard deviation with other skeletal-age calculation techniques.Öğe Self-etching adesiv sistemlerin anti-bakteriyel özellikleri(İnönü Üniversitesi Sağlık Bilimleri Dergisi, 2014) Öztürk, Fırat; Yalçın, Muhammet; Arslan, Uğur; Ersöz, MustafaBu çalışmanın amacı, Direk Kontakt Testi (DKT) kullanılarak Self Etching Adeziv sistemlerinin antibakteriyel etkinliklerinin değerlendirilmesidir.
