Objective: The prevalence of oral mucosal lesions, together with information on the risk habits associated with oral health, such as tobacco and alcohol use, can help in planning future oral health studies and screening programs. Material and Methods: This study presents the findings of 805 oral mucosal biopsies from patients, received over twelve years period. The cases represent 0.6 per-cent of the total number of reports examined (130.680). The data were revised and compiled for diagnosis site, age, and sex. The patients were divided into nine age groups according to decades. The classification was modified and divided into eleven main groups Results: Connective tissue lesions formed the largest group of diagnoses (24.4per cent) followed by white lesions (17.8 %per cent), verrucal-papillary lesions (15.4%per cent), red-blue lesions (14%per cent), ulcerous lesions (12.2%per cent), periodontal diseases (10%per cent), lymphoid tissue lesions (1.3%per cent), other tumors (2%per cent), pigmented lesions (0.6%per cent) only 1 metabolic disease (cherubism) (0.1per cent). Approximately 60 %per cent of the biopsies were from the second group patients with an almost equal distribution among sexes. The predominant site of the biopsies was gingiva (28%per cent) followed by lips (19.2%per cent). Conclusion:  The majority of the lesions were in the category of reactive and inflammatory lesions with most occurring in the thirty age group (31-40 age) that represents permanent dentition. These results suggest that the difficulties in maintaining oral hygiene or the presence of trauma may be the primary factor in mucosal lesions occurring in the permanent dentition period.

Preschool children (n=721) aged between 4 and 5 years were examined and 60 were selected. Two pairs of dental casts were obtained for each child. The first pair was from primary dentition before eruption of permanent first molars; the second pair had the permanent first molars in occlusion. The sample was divided into 3 groups, according to the terminal plane. The findings indicate that 55% of the group with flush terminal plane developed into Class I, 40% into Class II, and 5% into Class III molar relationship in the permanent dentition. The group with mesial step, 70% progressed to Class I, 25% to Class II, and 5% to Class III molar relationship in the permanent dentition. Finally, the group with distal step developed into Class II in the permanent dentition. It can be concluded that the terminal relationship of deciduous second molars was associated with the permanent first molars occlusion.

Abstract Aim Talon cusp is the name given to the accessory tubercles located on the lingual faces of anterior teeth. The occurrence of talon cusps has been reported among Europeans and Asians. However, there are few reports of this anomaly in Caucasians as well as a paucity of literature on its characteristics. Today there are seven million Turkish citizens of Caucasian origin that have settled in the Marmara, Central-Anatolia, East-Anatolia, and Black Sea regions of Turkey. The aim of this study is to present 27 Caucasian cases with 33 taloned teeth. This study is the first that was undertaken to investigate the characteristics of talon cusps in a group of Turkish people. Methods and Materials A survey of 27 patients examined in the Department of Oral Diagnosis and Radiology at Ondokuz Mayıs University in Samsun, Turkey between January, 2003 and June, 2006 was conducted. Their ages ranged from seven to 33 years. A total of 33 talon cusps were diagnosed in the 27 patients. The patients’ records and radiographs were evaluated and the following variables were studied: age, sex distribution, affected tooth, type of talon cusp, radiographic evidence of pulp extension, and associated dental anomalies and complications. Results There were 13 male and 14 female patients with a gender ratio of approximately 1:1. Ten of 33 talon cusps (30%) were seen in maxillary right central incisors while four cases (12%) were in maxillary left central incisors and nine cases (27%) were in maxillary right lateral incisors. Eight cases (24%) were seen in maxillary left lateral incisors, one case (3%) was in a mandibular right central incisor, and one case (3%) was in a mandibular left canine. Fifteen (15) of the 33 talon cusps were Type 1 talons (45%), while eight cases (24%) were Type 2 talons and ten cases (30%) were Type 3 talons. Twelve of the 33 talon cusps (36%) showed radiographic evidence of pulpal extension into the tubercule on periapical radiographs. One patient had gemination (3%) on the maxillary permanent incisors and two patients had mesiodens (6%) in the maxillary anterior region. Conclusion The talon cusp remains as one of the more uncommon dental anomalies worldwide and in Turkey and presents with different clinical features. Clinical Significance The talon cusp may be more likely to be associated with other odontogenic anomalies and some systemic conditions; early recognition of this anomaly is essential to provide proper treatment.

We recently proposed a novel method that aggregates the multidimensional aging pattern across the brain to a single value. This method proved to provide stable and reliable estimates of brain aging – even across different scanners. While investigating longitudinal changes in BrainAGE in about 400 elderly subjects, we discovered that patients with Alzheimer’s disease and subjects who had converted to AD within 3 years showed accelerated brain atrophy by +6 years at baseline. An additional increase in BrainAGE accumulated to a score of about +9 years during follow-up. Accelerated brain aging was related to prospective cognitive decline and disease severity. In conclusion, the BrainAGE framework indicates discrepancies in brain aging and could thus serve as an indicator for cognitive functioning in the future.

It is evident that hyperdontia is more common in the permanent dentition than in the primary. There is a considerable difference between males and females in the prevalence of these teeth in permanent dentition; hyperdontia is twice as common in males as in females. However, this approximation varies in terms of location, other associating syndromes that may be present, and the ethnicity of the individual. In terms of ethnicity, it can be seen that hyperdontia is in fact less common in Caucasian than in Asian populations. There is evidence to show that an individual is more likely to have hyperdontia if other members of their family also have the condition. Hence the present study was planned for evaluation of occurrence of hyperdontia in non-syndromic  population from Bihar Region. The present study was planned in Public Health Dentistry, Patna Dental College and Hospital, Patna, Bihar. Total 195 patients referred to Department of Dentistry were evaluated in the present study. Panoramic radiographs and clinical records of patients above the age of 18 years and without any syndromic features were selected for the study.  All the radiographs were examined for the presence of supernumerary teeth, their location, morphology, and number. Morphologically, teeth were classified as conical, tuberculate, supplemental, and odontoma. Early diagnosis of dental anomalies can prevent some esthetic, orthodontic, and periodontal problems, and knowledge of the prevalence and distribution of the anomalies may help clinicians to the detection of these anomalies at early stages. Our study evaluated the prevalence of selected dental anomalies; future studies should investigate the prevalence of dental anomalies of all types.

Türkiye'de 20.yy'ın ortasından itibaren başlayan iç göçler zamanla kurulan göçmen ağları ile süreklilik kazanmış ve ülke içinde nüfusun kır-kent dağılımını değiştirecek boyutlara erişmiştir. Araştırma, göçün doğum yeri verisinden hareketle ikamet edilen yerdeki nüfus miktarına göre alınan ve verilen göç akışının büyüklüğünü iller ölçeğinde yönlü ağlar kullanılarak analiz edilmesini amaçlamaktadır. Araştırmada, TÜİK tarafından yayınlanmış olan 2015 yılına ait, iller ölçeğinde doğum yerine göre ikamet yeri verisi kullanılmıştır. Göçün kaynak ve hedef sahaları arasındaki akışını incelemek için NodeXL ile oluşturulan tek modlu, yönlü ve ağırlıklandırılmış göç ağının istatistiksel olarak tam ağ yapısına sahip olduğu görülmüştür. Ağ grafiklerinden ve istatistiklerinden göç hareketinin doğudan batıya doğru gerçekleştiği ve İstanbul’ un ülkenin tamamına hâkim bir görünüme sahip olduğu anlaşılmaktadır. Türkiye nüfusunun cumhuriyet tarihi içinde geçirdiği iç göç süreçleriyle birlikte ülke içinde kurulmuş ve oldukça karmaşık bir görünüme sahip ağ yapısının olduğu ileri sürülebilir. Kurulan ağlar göçlerin devamını sağladığı gibi, göçün yöneldiği merkezlerde daha heterojen nüfus yapılarının ortaya çıkmasına yol açmıştır.ABSTRACT IN ENGLISHSocial Network Analysis of Migration Inter Provinces In Turkey with Nodexl The internal migrations which started in Turkey in the middle of the 20th century have gained permanency with the migration networks that were established at the time and reached dimensions which have the potential to change the rural-urban distribution of the population within the country.  The study aims to analyze the magnitude of the incoming and outgoing migration flow at the provincial scale based on the population data for place of birth according to place of residence by using directional networks. Place of residence according to place of birth at the provincial scale data for 2015 published by TÜİK was used in the study. A single mode, directional and weighted migration network created with NodeXL to examine the migration flows between the source and target has a statistically complete network structure. The network graphs and statistics show that the migrations have taken place from east to west and Istanbul has a view as dominant of the country. It can be argued that internal network structure of Turkish population has  a very complex view because of internal migration in the history of the republic. The established networks have enabled the continuation of migration and have manifested as the emergence of more heterogeneous population structures in centers where migration had been directed.
