    Objective. The aim of this study was to determine the prevalence of pulp stones (PS) in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. Materials Methods. A retrospective study was performed using bitewing radiographs of 814 patients ranging in age from 15 to 65. All data (age, sex, and location) was obtained from the files. These patients were analyzed for pulp stones. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Results. Of the patients, 462 (56.8%) were female and 352 (43.2%) were male. Sixty (12%) had one or more teeth that contained pulp stones. Pulp stones were identified in 518 (63.6%) of the subjects and in 2391 (27.8%) of the teeth examined. Pulp stone occurrence was significantly more common in the females than in males. With the increasing of age, the prevalence of pulp stones increased. Molars had statistically more pulp stones than premolars. Pulp stones were significantly more common in the maxilla compared with mandible. Conclusion. Prevalence of pulp stones in Turkish population was 27.8% but further larger-scale studies are required to assess its prevalence in the general population to compare it with other ethnic groups.

    Cephalometric Evaluation of Turkish Children With Class III Malocclusion in the Mixed Dentition
    (Aves Press Ltd, 2013) Celebi, Ahmet Arif; Tan, Enes; Gelgor, Ibrahim Erhan; Colak, Tugba
    Objective: To investigate the cephalometric characteristics of Turkish children with Class III malocclusion and compare them with to those of children with clinically normal occlusion during the mixed dentition phase. Materials and Method: Lateral cephalometric radiographs of 80 children with Class III malocclusion (mean age, 10.23 years) and 80 subjects with normal occlusion (mean age, 10.79 years) were examined for the study. Mean values of 13 linear and 21 angular cephalometric parameters were measured and compared. Results: Sagittal skeletal measurements included SNB (Class III, 81.82 +/- 4.26; control group, 74.5 +/- 3.86; p <.001), ANB (Class III, -2.35 +/- 2.02; control group, 2.4 +/- 1.17; p <.0001), Pg to Nasion vertical (Class III, -5.70 +/- 2.68; control group, -9.60 +/- 3.21; p <.05), Wits appraisal (Class III, -5 +/- 4.57; control group, -0.8 +/- 2.44; p <.05), Co-A (Class III, 79.38 +/- 2.19; control group, 83.94 +/- 2.64; p <.01) and Co-Gn (Class III, 105.7 +/- 2.04; control group, 102.4 +/- 1.15; p <.05). Vertical skeletal analysis included Gonial angle (Class III, 132.6 +/- 7.15; control group, 122.1 +/- 6.6; p <.01), and S-Ar length (Class III, 28.31 +/- 0.9; control group, 30.2 +/- 1.4; p <.05). Dentoalveolar measurements included U1 to SN (Class III, 107.96 +/- 8.13; control group, 98.4 +/- 8.19; p <.05). Soft tissue measurements included soft tissue convexity (Class III, 173.4 +/- 3.68; control group, 165.9 +/- 3.25; p <.01). Conclusion: The findings of the study indicated that effective mandibular length was larger in Class III groups and effective maxillary length was smaller in Class III groups.

    Comparison of Soft Tissue Cephalometric Norms between Turkish and European-American Adults
    (Hindawi Ltd, 2013) Celebi, Ahmet Arif; Tan, Enes; Gelgor, Ibrahim Erhan; Colak, Tugba; Ayyildiz, Erdem
    One of the most important components of orthodontic diagnosis and treatment planning is the evaluation of the patient's soft tissue profile. The main purpose of this study was to develop soft-tissue cephalometric standards for Turkish men and women and compare them with the cephalometric standards of normal European-American white people. The sample included 96 Turkish adults (48 women, 48 men), aged 20 to 27 years. Turkish subjects have increased facial convexity associated with retruded mandible, more obtuse lower face-throat angle, increased nasolabial angle and upper lip protrusion, deeper mentolabial sulcus, and smaller interlabial gap compared with European-American white people. It is appropriate to consider these differences during routine diagnosis and treatment planning of a Turkish patient or an American patient of European ancestry. Turkish males reveal more obtuse mandibular prognathism and upper lip protrusion, and smaller nasolabial angle than females.
