Öğe 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.Öğe Does chlorhexidine affect the shear bond strengths of orthodontic brackets?(Association for Dental Sciences of the Republic of China, 2011) Catalbas B.; Ercan E.; Dalli M.; Gelgor I.E.; Erdemir A.Background/purpose: The purpose of this study was to examine the effect of 1% chlorhexidine (CHX) gel on the shear bond strength (SBS) of orthodontic brackets bonded with Transbond XT (XT, 3M Unitek) and Transbond Plus Self-Etching Primer (TSEP, 3M Unitek). Materials and methods: In total, 75 extracted premolars were collected and randomly divided into five groups of 15 teeth each. Brackets were bonded to teeth using a different experimental technique for each group as follows: (I) (control): etch/dry/Transbond XT; (II) CHX gel/etch/dry/Transbond XT; (III) etch/dry/CHX gel/Transbond XT; (IV) dry/TSEP; and (V) CHX gel/dry/TSEP. All products were used according to the manufacturers' instructions. An Instron Universal Testing Machine was used to directly apply an occlusal shear force onto the enamel-bracket interface at a speed of 0.5 mm/min. Residual adhesive on each tooth was evaluated using an adhesive remnant index (ARI). Analysis of variance was used to compare the SBS of the groups, and a Chi-squared test was used to compare ARI scores. Results: Group I had the highest mean SBS (16.47 ± 4.2 MPa), followed by Groups II (16.24 ± 4.5 MPa), III (13.08 ± 4.50 MPa), IV (11.95 ± 2.7 MPa) and V (11.16 ± 2.8 MPa). No statistical differences were observed between Groups I and II (P > 0.05) or between groups IV and V (P > 0.05). However, SBS scores for Groups IV and V were significantly lower than those of Groups I and II (P > 0.05). No significant difference was observed in ARI scores among any of the groups (P > 0.05). Prior application of CHX gel did not significantly affect the SBS of orthodontic bonding adhesives. © 2011, Association for Dental Sciences of the Republic of China.Öğe Early childhood caries update: A review of causes, diagnoses, and treatments(2013) Çolak H.; Dülgergil C.; Dalli M.; Hamidi M.Dental caries (decay) is an international public health challenge, especially amongst young children. Early childhood caries (ECC) is a serious public health problem in both developing and industrialized countries. ECC can begin early in life, progresses rapidly in those who are at high risk, and often goes untreated. Its consequences can affect the immediate and long-term quality of life of the child?s family and can have significant social and economic consequences beyond the immediate family as well. ECC can be a particularly virulent form of caries, beginning soon after dental eruption, developing on smooth surfaces, progressing rapidly, and having a lasting detrimental impact on the dentition. Children experiencing caries as infants or toddlers have a much greater probability of subsequent caries in both the primary and permanent dentitions. The relationship between breastfeeding and ECC is likely to be complex and confounded by many biological variables, such as mutans streptococci, enamel hypoplasia, intake of sugars, as well as social variables, such as parental education and socioeconomic status, which may affect oral health. Unlike other infectious diseases, tooth decay is not self-limiting. Decayed teeth require professional treatment to remove infection and restore tooth function. In this review, we give detailed information about ECC, from its diagnosis to management.Öğe Effects of two different restorative materials on microleakage of class v cavities(Cumhuriyet University Faculty of Dentistry, 2010) Baglar S.; Dalli M.; Çolak H.; Ercan E.; Mustafa Hamidi M.Purpose: The aim of this study is to evaluate the micro-leakages of a composite restorative material and a high viscosity glass ionomer cement restorative material in class V cavities at in-vitro conditions. Materials and Methods: In this study, 30 extracted, caries-free human superior premolar teeth were used. Class V cavities were prepared on buccal surfaces of all teeth which were standardized to be 1mm below from the enamel-cement session. Teeth were randomly separated into two groups, each consists of 15 teeth. In first group the prepared cavities was filled with a composite resin (S3 Bond + Clearfil Esthetic; Kuraray, Tokyo, Japan). And in the second group the cavities was filled with high flowable glass ionomer cement (Fuji IX GP; GC, Tokyo, Japan). The restorative materials polimerizated with using a LED (Elipar Freelight; 3M ESPE, Seefeld, Germany) light source. All specimens were stored in distilled water for 24 hours. And all specimens were subjected to 10000 times thermal cycles of 5 degrees C/55 degrees C for 1 minute each. Teeth covered with nail polish except 1mm circumference of restorations and stored in %1 methylene blue solution for 24 hours. After washing, the teeth were sectioned perpendicular at bucco-lingual direction and evaluated under ax15 stereomicroscope. The scores were statistically analyzied using the Kruskal-Wallis and the Mann Whitney U tests. Findings: There were not any statistical difference between the experimental groups (p>0.05). In group 1, cervical and occlusal micro-leakage scores were statistically different (p<0.05). Although in group 2, there were no statistical differences between the cervical and occlusal microleakage scores. Results: The both restorative materials used in class V cavities, had been found successful in micro-leakage evaluation.Öğe The evaluation of reasons for replacement of amalgam and composite(2013) Bahsi E.; Ince B.; Dalli M.; Sahbaz C.; Colak H.; Acikan I.; Aslan N.Amalgam and composite restorations take prime place in restorative dental practices. Over time, restorations are replaced for various reasons. This study aimed to evaluate the reasons for restoration replacement of patients presenting at Dicle University, Dental Faculty, Restorative Dentistry Clinic. The study comprised 705 patients (402 female, 303 male) who presented at the dental clinic for routine dental treatment. Without taking gender into consideration, patients aged 15-80 who were determined to have amalgam and composite filling problems were included in the study. The patients were allocated to 5 groups according to age: Group 1, 16-25 years, Group 2, 26-35 years, Group 3, 36-45 years, Group 4, 46-55 years, Group 5, 56 years and over. The failure of the fillings was diagnosed from clinical and radiological evaluation results. The age, gender and reason for the replacement of the restoration were recorded for all patients. The obtained data was evaluated with Student's t test and a difference was determined between the age groups. Of 705 restorations, 378 (53.62%) were amalgam and 327 were composite (46.38%). When the reasons for replacement of restorations were examined the primary reason was secondary caries (30.78%), followed by fracture of the restoration (17.6%) and overflowing filling (15.46%). A significant difference was found between the age groups in terms of the parameter of reason for restoration replacement (p<0.05). To determine between which age groups this difference was more significant, the Tukey HSD test was applied as a multiple comparison test. The most significant reason for replacement of amalgams and composites was found to be secondary caries. The factor of gender had no effect on the reasons for replacement of the restoration. Failure of the restoration was seen to be greater in the 16-25 age group.
