    (Elsevier Ireland Ltd, 2019) Ozveren, Neslihan; Serindere, Gozde; Meric, Pamir; Cameriere, Roberto
    Tooth development evaluation is majorly the current approach to identify age and maturity. Dental age (DA) is therefore considerably emphasized in forensic and pediatric dentistry. The aim of this study was to assess the applicability of Willems and Cameriere methods for Turkish children. Panoramic images of 636 Turkish healthy children (319 male; 317 female) aged between 6 and 15 years were assessed. DA of the subjects was determined by using Willems and Cameriere methods. The seven right and left permanent lower teeth were valued using these two methods. The mean chronological age (CA) of the subjects was 11.53 +/- 2.25 (min:6, max:14.99) years (boys: 11.29 +/- 2.34 years, girls: 11.77 +/- 2.15 years). Willems method overestimated the CA (p <= 0.001), in contrast, Cameriere method underestimated the CA (p <= 0.001) for both sexes. In different age groups the mean difference between the CA and DA calculated by Cameriere method (CA-DA) ranged from 0.86 to -0.41 years for boys and from 1.00 to -0.21 years for girls, while the mean difference between the CA and DA calculated by Willems method ranged from -0.26 to -0.71 years for boys and from 0.19 to -0.76 years for girls. Cameriere method provided a better percentage of accuracy (84.6% and 77.3% for males and females, respectively) in the absolute difference values within 1 year compared to Willems method. Cameriere method performed slightly better but, both methods may be used for DA estimation in the Turkish population. (C) 2019 Elsevier B.V. All rights reserved.

    Volumetric measurements of mandibular incisor root resorption following Forsus FRD EZ2 and Bionator appliance treatment using cone-beam computed tomography: A preliminary study
    (Scientific Scholar Llc, 2020) Meric, Pamir; Zortuk, Fundagul Bilgic; Karadede, M. Irfan
    Objectives: Root resorption is one of the frequently encountered problems in orthodontic treatments. The effects of functional appliances on root resorption have not been clearly demonstrated. The aim of this study was to compare volumetric root resorption of mandibular incisors after Bionator and Forsus appliance treatment using cone-beam computed tomography (CBCT). Materials and Methods: The study sample (n = 30) was selected from Class II div. 1 mandibular retrognathia patients treated with the Bionator and Forsus appliances. The first CBCT scans were taken before Bionator use and after 6 months. In the Forsus group, the first CBCT scans were taken before Forsus appliance use and after an overcorrected Class I relationship was obtained. The mean treatment time with the Forsus appliance was 5 +/- 1.2 months. Mimics software was used for segmentation and volumetric measurements of mandibular incisor teeth root resorption. Results: In the Bionator group, statistically significant root volume loss was not found. In the Forsus group, the differences between before and after the treatment were not statistically significant for teeth 41, 31, and 32 (P > 0.05), whereas the difference was statistically significant for the lower right second incisor (P < 0.002). The percentage of volume loss (%) and root volume loss (mm(3)) was not statistically significant between groups. Conclusions: Following functional treatment with the Bionator and Forsus, statistically significant difference was not found between groups for mandibular incisor root resorption.
