    EFFECT OF MOBILE PHONES ON TRACE ELEMENTS CONTENT IN RAT TEETH
    (Taylor & Francis Ltd, 2008) Adiguzel, O.; Dasdag, S.; Akdag, M. Z.; Erdogan, S.; Kaya, S.; Yavuz, I.; Kaya, F. A.
    Widespread use of wireless communication made it necessary to investigate the long term effect of mobile phone, which is the most popular technological equipment in the earth. One of the important parts of body that absorbs, radiation emitted from mobile phones is oral tissue. However mobile phone users and also scientists usually do not pay attention on effect of mobile phone e exposure on oral tissue. Therefore, there is no epidemiological and experimental studies focused on this part of body. The aim of this study was to investigate the of GSM (Global System for Mobile Communication) -Modulated 900 MHz radiofrequency radiation 017 trace element content of rat teeth. Thirty one Wistar Albino adult male rats were divided into three groups: experimental group (each, n=14), shame group (n=7), and cage control group (n=10). Head of the rats in the experimental group were & exposed to GSH-Modulated 900 MHz radiofrequency radiation for 2 hours per day during ten months. At the end of the exposure period, the contents of some trace elements as Ca, Mg, Zn, and P were measured in the oral tissue. The measurements were performed by Atomic Absorption Spectrophotometry (AAS). However phosphorus content of teeth was measured h.); ultraviolet spectrophotometer (UVS). Changes of Mg, and Zn contents in the experimental group were found to be statistically significant according to the sham and cage control groups. Ca and P contents in the (experimental group were higher than the sham and cage control groups. Difference between the groups was not statistically significant (p>0.05). The results of the study showed that GSM-Modulated 900 MHz radiofrequency radiation can be a factor to alter the teeth trace elements' densities. However further studies are necessary to know whether GSM-Modulated 900 MHz radiofrequency, radiations affects the oral tissues such as the teeth.

    The effects of extremly low frequency magnetic field and mangan to the oral tissues
    (Diagnosis Press Ltd, 2008) Kaya, S.; Celik, M. S.; Akdag, M. Z.; Adiguzel, O.; Yavuz, I.; Turnen, E. C.; Ulku, S. Z.
    Exposure to extremely low frequency magnetic field (ELFMF) originating from daily electrical-electronic appliances and electric lines, is a common thing. Recently, the discussions focused on the topic whether ELFMF had any harmful effects over health or not. Several previous studies displayed that ELFMF significantly increased bone mineral density. The aim of the present study was to investigate the influence of ELFMF and manganese over mineral accumulation in head and jaw bones of rats. Previous studies showed that manganese plays a significant role over normal development of enamel and dentin alongside contributing to the calcium and phosphorous association. In the present study, the effects of exposure to ELFMF and manganese on mineral density and histology of teeth, were investigated. In the present study, 64 male Wistar albino rats were divided into 8 groups. Amount of mineral elevations were determined in head and jaw bones of the first 6 groups (p <.05) and histologic alterations were found in teeth of rats. The obtained results indicated that ELFMF plays an important role over mineral density and histologic structure of cranial and jaw bones in rats. In conclusion, further epidemiological and experimental laboratory studies are required for more detailed evaluation of the effects of ELFMF on cranial and jaw bones of rats.

    Incisor trauma in a Turkish preschool population: Prevalence and socio-economic risk factors
    (F D I World Dental Press Ltd, 2011) Tumen, E. C.; Adiguzel, O.; Kaya, S.; Uysal, E.; Yavuz, I.; Ozdemir, E.; Atakul, F.
    Objective: This study aimed to assess the prevalence of traumatic injuries of the primary incisors in preschool children from 2 to 5 years old in South-Eastern Anatolia, Turkey. Additionally, the relationship between traumatic dental injuries, parents' education level, family income, size of incisal overjet and the presence of anterior open bite were examined. Basic research design: A cross-sectional survey Clinical settings: Data were collected through oral examinations and structured interviews, and included socio-economic indicators. Participants: A total of 727 children of both genders were included in the study. 122 of these children were aged 2; 183 aged 3; 178 aged 4 and 186 aged 5. Results: The prevalence of dental injuries was 8.0% (n=58). The highest frequency of trauma in the primary teeth was observed at the age of 4. Boys experienced more dental injuries than girls, 12.2% and 4.0%, respectively. The most common crown fracture was in enamel only (57%) followed by crown fracture of enamel and dentin (19%). Conclusion: The prevalence of dental injuries in Turkish preschool children was very low. The children with incisal overjet greater than 5mm and anterior open bite experienced more dental injuries in primary teeth than their counterparts with normal occlusion. Socio-economic indicators were not statistically significantly associated with the occurrence of traumatic dental injuries.
