Effect of white cheese and sugarless yoghurt on dental plaque acidogenicity

sonmez, isil/0000-0002-3530-0244WOS: 000245758200008PubMed: 17426401White cheese and sugarless yoghurt are frequently consumed traditional Turkish foods. The aim of this study was to assess their acidogenic potential when eaten alone or following a rinse with sucrose solution. Plaque pH was measured by a pH microelectrode at baseline to determine the resting plaque pH and at time intervals of 1-60 min after rinsing with 10% sucrose solution or eating the test food for 1 min. White cheese consumption for 1 min increased the plaque pH. When white cheese was eaten 5 min after rinsing with 10% sucrose solution, the plaque pH rose rapidly. After sugarless yoghurt consumption, the pH fell to a similar minimum as for sucrose after 5 min but returned to baseline levels after 30 instead of 60 min. Consumption of sugarless yoghurt after a sucrose rinse initially reduced the plaque pH further but did not affect the time taken for pH to regain baseline levels. Copyright (c) 2007 S.

Assessing Changes in Oral Health-Related Quality of Life Following Dental Rehabilitation under General Anesthesia

WOS: 000337336200014PubMed: 25095323Objective: To determine whether dental treatment under general anesthesia (GA) improved oral health-related quality of life (OHRQoL) in pre-school children, to evaluate the sensitivity and responsiveness of the Turkish version of the Early Childhood Oral Health Impact Scale (ECOHIS) and to examine parental satisfaction with the care received Study design: The parents/caregivers of 120 pre-school children receiving dental treatment under GA, were asked to complete the ECOHIS before and after treatment. Participants were also asked a global transition judgement concerning change in their child's condition after treatment. Global transition judgement and distribution changes in ECOHIS scores were used to assess the sensitivity and responsiveness. Results: 98 children completed the follow-up survey Between pre- and post-treatment ECOHIS scores, significant reduction was observed (p<0.001). The effect sizes were moderate and large (0.36 to 1.63). Global transition rating groups were compatible with statistical differences between pre- and post-treatment scores, supporting the responsiveness of the ECOHIS. 91% of parents regarded the experience to be positive. Conclusions: Children's OHRQoL showed significant improvement after treatment. The majority of parents reported a high degree of satisfaction. Also, Turkish version of the ECOHIS was sensitive to dental treatment under GA for pre-school children and responsive to treatment-associated changes

Geological and hydrogeochemical properties of geothermal systems in the southeastern region of Turkey

Yesilnacar, Mehmet Irfan/0000-0001-9724-8683; UZELLI, TAYGUN/0000-0003-0846-5921; BABA, ALPER/0000-0001-5307-3156WOS: 000458467900021The Anatolia region is one of the most seismically active regions in the world. It has a considerably high level of geothermal energy potential thanks to its geological and tectonic settings. The Southeastern Anatolia Region (GAP) is located in the south of Bitlis-Zagros Suture Zone (BZSZ) which is in the Arabian foreland. During the neotectonic period, the folded structures have been developed under the influence of tectonic compression from the Upper Miocene in the GAP Region where it is closely related to active tectonics. These tectonic activities produce more geothermal resources. Few studies have been carried out in this region for geothermal energy. Limited portions of the geothermal resources have been used both for thermal tourism and greenhouses in the GAP region. The aim of this study is to determine geological, tectonic and hydrogeochemical properties of a geothermal system in the GAP Region. The result indicates that the surface temperatures of geothermal fluids are from 20 to 84.5 degrees C A large number of abandoned oil wells, whose temperature reaches 140 degrees C, are found in the region. Also, hydrogeochemical results show that deep circulated geothermal fluids are enriched with Na-Cl and shallow geothermal system fluids have Na - HCO3 and Ca-SO4 characters because of cold water mixing and water-rock interaction. Cold waters are generally of Ca-Mg - HCO3 and Ca - HCO3 type. Cation geothermometers were used for determining reservoir temperature of the geothermal resources in the region. The results show that the reservoir temperature of these geothermal resources ranges from 50 degrees C to 200 degrees C. The isotope data (oxygen-18, deuterium and tritium) suggests that geothermal fluid is formed by local recharge and deep circulation
