    Effects of Different Disinfection Methods on Microleakage of Giomer Restorations
    (Georg Thieme Verlag, 2019) Mutluay A.T.; Mutluay M.
    Objectives The purpose of this in vitro study was to investigate the effects of different disinfection methods on microleakage of Class V Giomer restorations. Materials and Methods Class V cavity preparation was performed on 40 sound permanent central incisors. Class V cavities (3 x 2 x 2 mm) were prepared on the buccal surfaces of the selected teeth. The teeth were randomly divided into four groups, each to be disinfected with a different method: Group 1--Disinfection with 2% chlorhexidine, Group 2--Disinfection with 6% sodium hypochlorite, Group 3--Disinfection with erbium, chromium: yttrium-scandium-gallium-garnet laser, Group 4--Control (distilled water). BeautiBond adhesive and Beautifil II Giomer restoration materials were applied to all surfaces of the cavities after the disinfection of all groups. The teeth were thermocycled 5,000 times (5-55°C), and then were immersed in 0.5% methylene blue for 24 hours. After rinsing, the teeth were longitudinally sectioned and dye penetration was assessed under a stereomicroscope (40x) to evaluate microleakage. Statistical Analysis The results were statistically evaluated by using the Kruskal-Wallis and Mann-Whitney U tests. Results Statistically, no significant difference was found between all four groups (p > 0.05). There was no statistically significant difference in microleakage scores of study groups (p > 0.05). Also, the microleakage scores of the gingival margins were significantly higher than the incisal margins (p < 0.0001). Conclusions Application of the different cavity disinfectants has no effect on the microleakage of Class V Giomer restorations. © 2019 Dental Investigation Society.

    Prevalence of caries among preschool-aged children in a central Anatolian population
    (2013) Doğan D.; Dülgergil C.T.; Mutluay A.T.; Yildirim I.; Hamidi M.M.; Çolak H.
    Objective: Early childhood caries (ECC) is a particularly destructive form of tooth decay that afflicts young children. The etiology and associated factors of ECC should be studied adequately to overcome this health hazard. The aim of this study was to determine caries prevalence and its consequences in toddlers in an Anatolian city, Kırıkkale. Materials and Methods: Examinations were performed in family medicine centers by three calibrated dentists during a period of 6 months. The status of dental caries was recorded according to the World Health Organization (WHO) criteria. We recorded the clinical indexes of decayed, missed, and filled teeth (DMFT and dmft; upper-case letters refer to permanent and lower-case letters to primary teeth), and decayed, missed, and filled surfaces (DMFS). Results: Totally 3171 toddlers were included (52% males and 48% females). The mean age was 25.8 ± 10.1 months. The prevalence of ECC in preschool children was 17.3%, while the mean df(t) was 0.63 ± 1.79. ECC increased significantly with age. Dental caries were mostly observed in primary maxillary central teeth. Occlusal and buccal surfaces were the most affected sites. The difference in distribution of caries between maxilla and mandibula was found to be statistically significant (P < 0.05). Conclusions: When compared to other data obtained from various epidemiologic studies, the toddlers living in Kırıkkale city center had a significant caries level. This observation had clearly suggested that early preventive measures should urgently be put into effect all over the city.
