    Clinical, radiographic, diagnostic and cephalometric features of pycnodysostosis in comparison with Turkish cephalometric norms: A case report
    (2012) Kamak H.; Kamak G.; Yavuz I.
    Pycnodysostosis is a rare genetic disorder and was first described in 1962 by Maroteaux and Lamy. The incidence of this anomaly is estimated to be 1.7 per 1 million births. The principal characteristics of this disorder are short stature, prominent eyes with blue sclera, beaked nose, cranial dysplasia, exposed fontanelles and cranial sutures, clavicular dysplasia, total/partial dysplasia of the terminal phalanges, obtused mandibular gonial angle, and generally increased bone density. Some features of pycnodysostosis are similar to osteopetrosis and cleidocranial dysostosis. Therefore, it must be distinguished from osteopetrosis and cleidocranial dysostosis in order to diagnose it in individuals of a younger age. The aims of this case report were to show the clinical, radiographic, and diagnostic features, as well as the cephalometric characteristics of pycnodysostosis in comparison with Turkish cephalometric norms.

    The effect of changes in lower incisor inclination on gingival recession
    (Hindawi Publishing Corporation, 2015) Kamak G.; Kamak H.; Keklik H.; Gurel H.G.
    Aim. Orthodontic treatment may promote development of recessions. The mechanism by which orthodontic treatment influences occurrence of recessions remains unclear. The aim of this study was to test the hypothesis that a change of mandibular incisor inclination promotes development of labial gingival recessions. Materials and Methods. The study sample comprised dental casts and lateral cephalograms obtained from 109 subjects before orthodontic treatment (Tb) and after orthodontic treatment (Ta). Depending on the change of lower incisor inclination during treatment, the subjects were divided into three groups: Retroclination (R), Stable Position (S), and Proclination (P). The presence of gingival recessions of mandibular incisors and clinical crown heights were assessed on plaster models. Results and Conclusions. From Tb to Ta, Inc-Incl showed a statistically significant change in the R, P, and S groups (p < 0.05). Increase of clinical crown heights of the lower incisors (42, 4, and 31) was not statistically significant in any group. The only statistically significant intergroup difference was the greater increase of the clinical crown height of tooth number 32 in the P group in comparison with the R group (p = 0.049). The change of lower incisor inclination during treatment did not lead to development of labial gingival recessions in the study sample. © 2015 Gulen Kamak et al.

    Evaluation of the relationship between periodontal risk and carotid artery calcifications on panoramic radiographs
    (Dental Investigations Society, 2015) Kamak G.; Yildirim E.; Rencber E.
    Objective: To evaluate if there is a relationship between findings of carotid artery calcification (CAC) and periodontal risk in nonsmoker subjects by using panoramic radiographs (DPR). Materials and Methods: A total of 1146 DPRs were investigated. Gender, age, severity of bone loss, tooth loss, periodontal risk, and findings of carotid calcification were recorded. The periodontal risk was evaluated and classified according to the degree of alveolar bone loss. Results: CAC was diagnosed in %13.6 (n: 156) of DPRs. Of 1146 patients, 338 (29.5%) had low, 668 (60%) had moderate, and 120 (10.5%) had high periodontal risk. A statistically significant relation was observed between carotid calcification and periodontal risk. Conclusion: Positive findings of carotid calcification may be related with periodontal problems. Clinicians must be careful about diagnosing CACs on DPRs during routine examinations. In the case of positive findings of CAC and periodontitis together, the patient may be consulted to a specialist for further investigation. © 2015 European Journal of Dentistry.
