    As a standart preventive method brushon fluoride application in primary schools: Four years field study results
    (Cumhuriyet University Faculty of Dentistry, 2015) Dülgergil C.T.; Hamidi M.M.; Dalli M.; Ercan E.; Türkoglu Ö.
    Objectives: The aim of this study was to evaluate the medium-and long-term effect of "brush on fluoride gel" application which is a simplified preventive method in a city center including whole primary schools. Materials and Methods: In 2007, of the 2348 first grade primary school children (born in 1999) being teached at 37 primary school at Kirikkale city center, 480 were selected, and equally divided as control and study groups. While in study group, all children had routinely get brush on fluoride gel application four-times a year during 3 years (total 12 times), using 2 percent neutral fluoride gel; others were subjected to oral hygiene education at least one time a year. All the examination procedures were yearly performed using World Health Organization (WHO) criteria at the first-second and fourth year. Results: While there was no statistically significant difference between the groups at baseline, it was not true at 4th years DMFT results (DMFT values for control and study groups were 0,33±0,72 and 0,69±1,15, respectively. p=0,001). Similar trend was observed at baseline and 4th year results for caries prevalence (p values for baseline and 4th year comparisons were p=0,049 and p=0,004, respectively). Conclusions: Considering as a simplified oral health preventive programs which may be important to established tooth-brushing habit could lead to an observational difference in caries prevalence. However, various primitive preventive methods could need to be supported by the risk-based additional preventive applications in high risk population.

    Human immunodeficiency virus/acquired immunodeficiency syndrome knowledge among high school students in Kirikkale province of Turkey
    (2013) Aylikçi B.U.; Bamise C.T.; Hamidi M.M.; Turkal M.; Çolak H.
    Background: The purpose of the present study was to assess the existing level of knowledge of high school children about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and the sources of their information. Materials and Methods: A cross-sectional survey was conducted in two high schools in Kirikkale, Turkey and data were collected by a self-administered questionnaire. Multi-stage sampling technique was used to obtain a representative sample. Results: Four hundred and seventy three participants; 230 males and 243 females were analyzed. Their ages ranged from 15 to 19 years with a mean age of 16.81 ± 1.27. 92.2% of the students claimed to have heard about HIV/AIDS prior to the study with slightly more females than males. Although with some misconceptions, majority of the participants knew that HIV is not transmitted by sharing meals, casual contact, and sleeping in the same room and using the same bathroom. 93.4% identified HIV/AIDS as a life-threatening disease and 27% believe that there is a cure for AIDS. 64% and 22.8% respectively believed that the people can protect themselves by using condoms and by avoiding sexual contact. Internet was preponderantly claimed as the most important source of information about HIV/AIDS. Conclusion: Empirical evidence from this study suggests that the students have a fairly high knowledge of HIV/AIDS. This is not without some misconceptions about the prognosis of the disease. Internet was the major source of HIV/AIDS information.

    One-year clinical evaluation of Quixfil and Gradia Direct composite restorative materials in posterior teeth.
    (2013) Doğan D.; Ercan E.; Hamidi M.M.; Aylikçi B.U.; Colak H.
    The purpose of this study was to evaluate and compare the 12 month clinical performances of two different posterior composites in Class I and Class II restorations. Class I and class II cavities of 62 patients, 74 Quixfil (Dentsply/ Xeno V) and 68 Gradia Direct (GC America/G bond) composite restorations were placed by two dentists. Only small and medium-sized cavities were included in the study. Independent evaluations were performed at baseline (one week), after three months, six months, and one year, by one trained examiner using the modified U.S. Public Health Service rating criteria. Color match, marginal integrity, anatomical form, surface roughness, marginal or interfacial staining, postoperative sensitivity, and secondary caries were evaluated. Both restorative materials showed only minor changes, and no differences were detected between their performance at baseline and after 12 months. Postoperative sensitivity was observed in only one Quixfil restoration. In regard to the clinical performance, there was no statistically significant difference between the materials used. Both materials showed good clinical results with dominant alpha scores at the end of 12 months.

    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.

    Shear bond strength of bulk-fill and nano-restorative materials to dentin
    (Dental Investigations Society, 2016) Colak H.; Ercan E.; Hamidi M.M.
    Objectives: Bulk-fill composite materials are being developed for preparation depths of up to 4 mm in an effort to simplify and improve the placement of direct composite posterior restorations. The aim of our study was to compare shear-bond strength of bulk-fill and conventional posterior composite resins. Materials and Methods: In this study, 60 caries free extracted human molars were used and sectioned parallel to occlusal surface to expose midcoronal dentin. The specimens were randomly divided into four groups. Total-etch dentine bonding system (Adper Scotchbond 1XT, 3M ESPE) was applied to dentin surface in all the groups to reduce variability in results. Then, dentine surfaces covered by following materials. Group I: SonicFill Bulk-Fill, Group II: Tetric EvoCeram (TBF), Group III: Herculite XRV Ultra, and Group IV: TBF Bulk-Fill, 2 mm × 3 mm cylindrical restorations were prepared by using application apparatus. Shear bond testing was measured by using a universal testing machine. Kruskal-Wallis and Mann-Whitney U-tests were performed to evaluate the data. Results: The highest value was observed in Group III (14.42 ± 4.34) and the lowest value was observed in Group IV (11.16 ± 2.76) and there is a statistically significant difference between these groups (P = 0.046). However, there is no statistically significant difference between the values of other groups. In this study, Group III was showed higher strength values. Conclusion: There is a need for future studies about long-term bond strength and clinical success of these adhesive and bulk-fill systems. © 2016 European Journal of Dentistry.
