    The effect of different enamel surface treatments on microleakage of fissure sealants.
    (2013) Topaloglu-Ak A.; Onçag O.; Gökçe B.; Bent B.
    The aim of this study was to evaluate the effects of different techniques of surface treatment on the microleakage of fissure sealants in permanent molar teeth in vitro. 96 extracted impacted human third molars were randomly divided into 8 surface treatment groups (n=12/group) as 1. Er: YAG laser ; (Fidelis II, Fotona, Ljubljana, Slovenia) (125 mj, 20Hz) ; 2. Er: YAG laser + 37% H3PO4 (15s) ; 3. ER: AG laser + 37% H3PO4+Prime&Bond NT ; 4. Er: YAG laser + G Bond ; 5. Er: YAG laser + Prime&Bond NT ; 6. 37% H3PO4 ; 7. 37% H3PO4 + Prime&Bond NT ; 8. G Bond. Sealant material (Clinpro, 3M ESPE, Seefeld, Germany), was applied into the fissures and light-cured for 20s with LED (Bluephase C5, Ivoclar-Vivadent, Schaan, Liechtenstein). Specimens were subjected to thermocycling (1000×, 5-55°C, dwell time: 15s) and immersed in 0.5% basic fuchsin solution for 24h at 37°C. The samples were sectioned and scored on a 3 point rating scale using a light microscope with a magnification of ×20. One-way analysis of variance was used to analyze data. Multiple comparisons were analyzed using Bonferroni test (p=0.05). Er:YAG laser showed the highest microleakage scores whereas Er YAG laser + 37% H3PO4 showed the lowest. Although 37% H3PO4 group showed higher scores than Er:YAG laser + 37% H3PO4, the difference was not statistically significant. Etching fissures with phosphoric acid is sufficient prior to fissure sealant application. Copyright © 2013 by Academy of Sciences and Arts of Bosnia and Herzegovina.

    Managing dental caries in children in Turkey - A discussion paper
    (2009) Topaloglu-Ak A.; Eden E.; Frencken J.E.
    Background. This paper describes the oral healthcare system and disease situation amongst children in Turkey. Considering the high prevalence and severity of dental caries, a proposal for improvement of oral health in this population group is formulated. Discussion. A virtual absence of palliative, preventive and restorative care characterises juvenile oral healthcare in Turkey. Consequently, carious cavities remain untreated, which may lead to pain, discomfort and functional limitation and, further, may impact negatively upon general health and cognitive development. As a first step to controlling dental caries, a national health programme including promotional, preventive and minimal intervention approaches for managing dental caries is proposed. The pros and cons of community-oriented caries-preventive measures are discussed. Daily tooth brushing with fluoridated toothpaste at home, in mother- and child-care centres, kindergartens, and schools is highlighted. Summary. The dental profession, government, university officials and other stakeholders need to meet and determine how best the oral health of children in Turkey can be improved. The present proposed plan is considered a starting point. © 2009 Topaloglu-Ak et al.

    Microhardness and surface roughness of glass ionomer cements after APF and TiF4 applications
    (Journal of Clinical Pediatric Dentistry, 2012) Topaloglu-Ak A.; Cogulu D.; Kocatas Ersin N.; Sen B.H.
    Objective: To evaluate whether TiF4 solution and APF gel had any adverse effects on the surface morphology of newly developed glass ionomers. Study Design: Fifteen disc-shaped specimens of Fuji IX Extra, Fuji II LC and Ketac N100 were prepared and stored in 2 ml of artificial saliva at 37 C for 8 weeks. Specimens of each material were divided randomly into three subgroups as 1 and 4 minutes application of 1.23% APF gel and 1 minute application of 1% TiF4 solution. Specimens were reaged for another 8 weeks. Microhardness, surface roughness values and surface morphology were evaluated by using Vicker's hardness test, surface profilometry and scanning electron microscopy (SEM) for all time interventions, respectively. One-way Anova test was performed and differences were compared by Tukey's HSD and Dunnet T3 test. Results: APF and TiF4 applications decreased microhardness significantly in Fuji II LC. In Fuji IX Extra microhardness decreased significantly after 1- and 4-min APF applications. Ketac N100 showed no difference in microhardness after APF and TiF4 applications. Surface roughness was not affected at any time interval for three restorative materials. Conclusion: Within the limitations of this vitro study, it was revealed that, potential adverse effects of APF and TiF4 applications might be material dependant. Hence, restorative materials should be selected in accordance with kind, frequency and application time of fluoridation to avoid deteriorations of the restorations.

    Perceived dental anxiety among schoolchildren treated through three caries removal approaches
    (Bauru School of Dentistry, University of Sao Paulo, 2007) Topaloglu-Ak A.; Eden E.; Frencken J.E.
    Objectives: The aim of the investigation was to test the differences in the perceived level of dental anxiety among children treated restoratively using the Atraumatic Restorative Treatment (ART) approach, the traditional restorative (TRA) approach and ART aided with a chemomechanical caries removal gel (ART plus). Methods: The study subjects were 6-7-year-old children. TRA was compared to ART in a clinical setting after children had seen a dentist twice (Group A), ART was compared to 'ART plus' in a clinical setting after children had seen a dentist once (Group B) and ART was applied outside the clinic on school premises (Group C). The treatments were carried out in Class II cavitated dentine lesion in primary molars. Dental anxiety was measured using the Venham Picture Test (VPT). Three-way analysis of variances and interaction was applied to test for treatment approach, gender and operator effects on the mean VPT scores. Results: There was no statistically significant difference (p=0.80) observed between the mean VPT scores for the traditional approach and those for the ART approach and between ART with and without a chemomechanical caries removal gel (p=0.07). Children in Group A had lower mean VPT scores than children in Group B (p=0.02) and Group C (p<0.00001) when treated using the ART approach by the same two operators. Conclusions: The level of dental anxiety was low. There was no difference in level of dental anxiety observed in children treated with ART in comparison to the traditional restorative approach, and between children treated with ART with and without a chemomechanical caries removal gel. The treatment environment and prepatory visits may be factors determining the level of dental anxiety in children treated through the ART approach only.
