Öğe Anticaries effect of atraumatic restorative treatment with fissure sealants in suburban districts of Turkey(Assoc Dental Sci Republic China, 2009) Ercan, Ertuğrul; Dülgergil, Çoruh Türksel; Dalli, Mehmet; Yıldırım, Işıl; İnce, Bayram; Çolak, HakanBackground/purpose: This 3-year field trial was performed to compare the effectiveness of high-viscosity atraumatic restorative treatment with glass ionomer sealant (ART-GIS) on the development of caries in a population of children living in two distinct localities in Diyarbakir City in southeastern Anatolia, Turkey. One of these was a suburban district with tow socioeconomic conditions and tacked routine dental care, and the other was located in the city center and had a moderate socioeconomic status with proximity to a welt-designed dental center. Materials and methods: Two primary schools were selected as study sites in these two locations. In total, 368 ART-GIS procedures were performed on 208 children aged 9-11 years, white 174 children who were students at another school in the center of the same city did not receive the sealant and served as controls. The clinical status of the ART-GIS was evaluated at the baseline and during the first, second and third years after placement. Differences between the two groups for each evaluation period were analyzed using Student's t test for the two independent groups. Results: The control group had nearly ten, five and three times greater numbers of new caries than did the ART group during the first, second and third years, respectively. The difference between the groups was statistically significant for each examination period with respect to the number of children having new caries (Student's t test, P < 0.001), and new caries occurrence (Student's t test, P < 0.001). Conclusion: These results clearly show that the ART-GIS procedure can be used as a preventive method in rural and/or suburban areas where other preventive approaches are neither available nor economical.Öğe As a standart preventive method brush- on fluoride application in primary schools: Four years field study results(2015) Dülgergil, Çoruh Türksel; Hamdi, Mehmet Mustafa; Ercan, Ertuğrul; Dallı, Mehmet; Türkoğlu, ÖzgeAmaç: Bu çalışma; bir il merkezindeki tüm ilköğretim okullarını kapsayan, basitleştirilmiş bir koruyucu diş hekimliği yöntemi olan Fırça ile florlu jel uygulamasının orta ve uzun süreçteki etkilerinin değerlendirilmesi amacıyla planlanmıştır. Gereç ve Yöntemler: 2007 yılında Kırıkkale ili merkezine bağlı ilköğretim birinci sınıfta öğrenim gören çocuklardan, çalışma ve kontrol grubuna eşit dağılmak üzere toplam 480 çocuk çalışmaya dâhil edildi. Çalışma grubuna %2lik nötral florlu jelin diş fırçası ile çocuklara birebir fırçalatılması (brush-on gel application) yöntemi ile yılda 4 defa ve 3 yıl boyunca olmak üzere toplam 12 uygulama yapılırken, kontrol grubuna ise yılda en az bir kere sınıf ortamında fırçalama eğitimi verildi. Grupların başlangıç, birinci, ikinci ve dördüncü yıl muayeneleri Dünya Sağlık Örgütünün (DSÖ) muayene kriterlerine göre gerçekleştirildi. Bulgular: Grupların başlangıç, birinci ve ikinci yıldaki DMFT değerleri arasında istatistiksel olarak anlamlı farklılık mevcut değilken, dördüncü yıldaki DMFT değerleri (sırasıyla 0,330,72 ve 0,691,15) arasında anlamlı farklılık bulundu (p0,001). Grupların başlangıç ve ikinci yıldaki çürük yaygınlık yüzdeleri arasında anlamlı farklılık gözlenmezken, ikinci ve dördüncü yılındaki çürük yaygınlık yüzdeleri arasında anlamlı farklılık mevcuttur (sırasıyla p0,049 ve p0,004). Sonuçlar: İlköğretim okullarında gecikmiş tip hijyen eğitiminin de verilebildiği basitleştirilmiş koruyucu uygulamalar, çürük artışının kontrol altına alınabilmesi açısından bir fırsat oluşturabilir. Bununla beraber bu tip basit yöntemler, yüksek çürük riskli hastalarda yetersizdirler ve risk bazlı koruyucu yöntemlerin desteğine ihtiyaç duyarlar.Öğe Avulse dişlerin replantasyonu: Olgu sunumu(2007) Ercan, Ertuğrul; Dallı, MehmetBu klinik çalışmanın amacı avulasyona uğramış dişlere uyguladığımız replantasyon tedavi tekniğinidir. Otuz beş yaşındaki erkek hastada dental travma sonucu maksillar sağ, sol ve mandibular sağ daimi kesici dişler avulsuyona uğramıştı. Avülse dişler parmaklarla hafif basınçla alveol soketine yerleştirildi. Dişler yarı sert arch teli ile splinte edildi Hastaya splinte dişleri kullanmaması, diğer dişlerini fırçalamasını ve sadece yumuşak gıdalar yemesini asitli içecekleri tüketmemesi tavsiye edildi. Dört hafta sonra splint çıkarıldı. Tedavisi sonucunda dişlerde semptom ve renk değişikliği, dişeti apsesi, dişlerde devitelizasyon, ağrı ve kök rezorbsiyon gözlenmedi.Öğe Can Dentin Surfaces Be Bonded Safely With Ozone and Boric Acid?(Taylor & Francis Inc, 2015) Ercan, Ertuğrul; Çolak, Hakan; Hamidi, Mehmet Mustafa; İbrahimov, Damla; Gülal, EsraThe aim of this study is to evaluate the effect of different cavity disinfectants on shear bond strength. In this study, 60 caries-free human molar teeth were used. Smooth dentin surfaces were revealed by cutting occlusal enamel and a standard smear layer was obtained by using 600-grid sandpaper. Specimens were randomly assigned to four groups according to the disinfectant used: Group 1: Control (no disinfectant); Group 2: Ozone; Group 3: Chlorhexidine, Group 4: Boric acid. Specimens were bonded using S3 Plus Bond and the composite buildups were created by using composite resin according to the manufacturer's instructions. After specimens were kept for 24 h, at 37 degrees C in distilled water, the shear bond strength test was measured with a universal test machine. The highest bond strength values were observed in the control group. The bond strength was significantly lower in the chlorhexidine, and boric acid-treated groups than it was in the control group (respectively, p = 0.046 and p = 0.028); however, no significant difference in the bond strength was observed between the ozone group and the control group (p = 0.444). The ozone group was detected as having the best shear bond strength values in groups which were applied to cavity disinfectants.Öğe The challenge of MDP monomer containing adhesive systems: Comparison of shear bond strengths(2015) Bağlar, Serdar; Bayraktar, Yusuf; Ercan, Ertuğrul; Mutluay, Abidin Talha; Şengün, AbdulkadirAmaç: Bu in - vitro çalışmanın amacı MDP monomeri içeren üç farklı self- etch adeziv sistemin makaslam a bağ dayanımınlarını değerlendirmektir. Materyal ve Metod: Bu çalışma için atmış adet çekilmiş insan üçüncü molar dişl eri kullanlmıştır. Dişler bir elmas kesme diski yardımıyla ve su soğutması altında kron boylarının orta üçlülerine kadar kesilmiştir. Kesilen dişler rastgele üç gruba ayrılmıştır (n20). Ultradent Bonding Jig yardımıyla ve üç farklı MDP içeren self-etch ad eziv sis tem kullanılarak restorasyonlar yapılmıştır (2,30 mm çap ve 3mm yükseklik). Sonrasında örnekler test cihazına alınmış ve makaslama bağlanma değerleri ölçülmüştür. Bulgu lar: 1. Ve 2. Grup restorasyonlar, 3.

Sonuç: Bu in -vitro çalışmanın sonuçlarına göre, bütün grupların optimal bağ değerlerigösterdiği saptandı. Ancak 1 . ve 2. Gruplar 3. Gruba oranla anlamlı derecede daha iyi bağlanma değerleri gösterdi.Öğe A combined application of ART-fluoride varnish for immigrant junior field-workers: 12-months follow-up field trial in rural Anatolia(Quintessence Publishing Co., Ltd, 2005) Dülgergil, Çoruh Türksel; Ercan, Ertuğrul; Yıldırım, IşılPurpose: Immigrant junior-field-workers in south eastern Anatolia, Turkey, had an impact on agriculture economy, and to provide an optimal dental service is crucial due to their multiple medical and dental problems. So, a combined preventive-operative method including ART-fissure sealant/restoration and fluoride varnish application was evaluated in terms of caries increment, cariogenic bacteria and lesion behavior at one-year follow-up period. Materials and Methods: A total of 27 children with 147 pit and fissure lesions displaying discoloration were included in this study. Of these, 15 children with 75 lesion and 12 children with 72 lesions were divided as test and control groups, respectively. Baseline caries values of each groups were 3.4 ± 1.4 and 2.5 ± 1.6 for test and control groups respectively (p < 0.05). Bacteriologic sampling was undertaken with the dip-slide method (Vivadent). A combined preventive-operative method was performed for the test group but not for the control group. After six months and one year, children were re-examined with respect to cariogenic bacteria in plaque, new caries occurrence and lesion characteristics. Results: Mean caries increment (?DMFT) for both the control and the test group were 1.91 ± 1.53 and 0.26 ± 0.43, respectively. The difference was found to be statistically significant (t = 8.35, p < 0.0001). More lesions in the control group did progress to cavitation than in the test group. A linear relationship was observed between plaque MS-score and cavitation, indicating that when plaque MS levels are high, cavitation does easily occur in the control group and vice versa in the test group (p < 0.0001 for all variables). Conclusion: It could be argued from these findings that a combined preventive-operative method could be applicable not only to treatment of dentinal lesions but also to retard, even prevent, the initial caries on pits and fissures of permanent teeth in rural districts where any other routine dental/preventive care is not feasible, and compliance of the individuals' hygiene is inadequate.Öğe A Comparison of Microleakage Scores of Five Different Types of Composite Resins(Taylor & Francis Ltd, 2010) Dallı, Mehmet; Bahsi, Emrullah; Şahbaz, Cafer; İnce, Bayram; Akkus, Zeki; Ercan, Ertuğrul; Atılgan, S. SerhatThis study aimed to perform a comparative assessment of microleakage in Class V cavities among five different composite resins For this purpose 100 fresh caries-free human permanent molars were randomly assigned to one of five groups (n=20) Clearfil Majesty Esthetic + Clearfil S3 Bond (Group I) TPH Spectrum + Xeno V (Group II) Gradia Direct Anterior + G Bond (GC) (Group III) Premise + Optibond All in One (Group IV) and Charisma + iBond (Group V) were applied and polymerized under LED Specimens were varnished immersed in 0 5% methylene and sectioned bucco-palatinally/lingually and microleakage scores were determined Gingival and occlusal microleakage scores among groups were statistically significant (p < 0 05) (p=0 043 p=0 005) Occlusal microleakage scores for Clearfil Majesty Esthetic and Premise were lower than in the other groups Charisma had the highest microleakage scores with no difference among the other groups (p > 0 05) In conclusion occlusal and gingival microleakage scores were satisfactory except for CharismaÖğe Effect of intracanal medication with calcium hydroxide and 1% chlorhexidine in endodontic retreatment cases with periapical lesions: An in vivo study(Elsevier Singapore Pte Ltd, 2007) Ercan, Ertuğrul; Dalli, Mehmet; Dulgergil, C. Turksel; Yaman, FerhanBackground/Purpose: Calcium hydroxide (Ca(OH)(2)) has been widely used as an intracanal medicament for endodontic retreatment, but very few studies used both Ca(OH)(2) and 1% chlorhexidine (CHX) as intracanal medicaments. The purpose of this study was to assess the in vivo effectiveness of a combination of Ca(OH)(2) and 1% CHX as intracanal medicaments in endodontic retreatment cases with periapical lesions. Methods: Previous cases of endodontically treated teeth with periapical pathosis in 70 patients (36 men and 34 women, age range 18-60 years) were included. Of these teeth, 59 had received root canal treatment and 11 had been subjected to previous apical surgery, indicating endodontic failure. Following the routine procedures, including canal reshaping and irrigation with 2% CHX, a canal medication material containing Ca(OH)(2) powder and a 1% CHX solution was placed into the root canals. Over a 6-week period, the intracanal medication was periodically changed until the teeth became asymptomatic. Patients were recalled at 3-month intervals for radiographic and clinical examination. Results: Our clinical and radiographic assessment of retreatment cases showed complete healing in 41 (64%) teeth, incomplete healing in 9 (14%) teeth, and failure in 14 (22%) teeth. For complete healing teeth, the healing time varied from 6 to 36 months. The size of the periapical lesions and previous surgical treatment had no influence on the prognosis. Conclusion: Our results suggest that a combination of Ca(OH)(2) and 1% CHX can be successfully used as intracanal medicament for disinfection in endodontic retreatment cases with periapical lesions.Öğe Effects of Different Chlorhexidine Formulations on Shear Bond Strengths of Orthodontic Brackets(E H Angle Education Research Foundation, Inc, 2009) Çatalbaş, Bülent; Ercan, Ertuğrul; Erdemir, Ali; Gelgör, İbrahim Erhan; Zorba, Yahya OrcunObjective: To test the hypothesis that the application of different chlorhexidine formulations to the etched enamel will not affect shear bond strength (SBS). Materials and Methods: Forty-four freshly extracted human premolars; were collected and stored in distilled water. The teeth were etched with 37% phosphoric and were rinsed and dried. The teeth then were divided into four equal groups. While Group 1 served as a control, Groups 2 to 4 were treated before bonding with a chlorhexidine formulation that included solution (2%), gel (1%), and mouthwash (0.2%). Orthodontic brackets were bonded with Transbond XT (3M Unitek, Monrovia, Calif). Bond strength results were evaluated with the use of one-way analysis of variance (ANOVA) (P < .05) and post hoc tests. Modes of failures were verified by means of scanning electron microscopy. Results: Although no statistically significant difference was observed between Groups 1 and 4 (P > .05), both were statistically superior to Groups 2 and 3 (P < .05). In this in vitro study, the observed measures for Groups 2 and 3 (14.5-10.6 MPa) were lower than those for Groups 1 and 4 (27.3-24.9 MPa), but these values were much higher than those required for clinical use (6-8 MPa). Conclusion: The hypothesis is rejected. The application of chlorhexidine mouth rinse before bonding had no significant effect on the SBS value, and the application of chlorhexidine solution and gel significantly decreased SBS. (Angle Orthod. 2009;79:312-316.)Öğe The effects of three different desensitizing agents on the shear bond strength of composite resin bonding agents(Elsevier Science Bv, 2010) Zorba, Yahya Orçun; Erdemir, Ali; Ercan, Ertuğrul; Eldeniz, Ayce Ünverdi; Kalaycıoğlu, Barış; Ülker, MustafaThe aim of this study was to evaluate the effects of three desensitizing agents on the shear bond strengths of four different bonding agents used to bond composite resin to dentin. A total of 160 extracted human molars were sectioned parallel to the occlusal plane under water cooling, polished and randomly divided into 4 groups of 40. Each group was treated with a different desensitizing agent (Tooth Mousse, Ultra-EZ, Cervitec Plus), except for an untreated control group. Each group was then randomly subdivided into 4 groups of 10, and a different dentin bonding agent (XP Bond, AdheSE, Adper Prompt L-pop, GBond) was applied to each group in order to bond the specimens to a resin composite (Gradia Direct) built up using a plastic apparatus. A Universal Testing Machine was used to measure the shear bond strength of each specimen. Statistical analysis was performed using one-way ANOVA and Tukey's tests. With the exception of the Control/AdheSE and Ultra-EZ/XP Bond groups, no statistically significant differences were found in the shear bond strength values of the groups tested. These findings suggest that the use of different desensitizing agents does not affect the shear bond strength of various adhesive systems used to bond resin composite to dentin.

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 Evaluation of school-based prevention program in Turkey: Results of a 24-month study(Dental Investigations Society, 2016) Dulgergil, Çoruh Türksel; Ercan, Ertuğrul; Çolak, HakanObjective: In this paper, cavity experiences of children with different levels of eruption and cavity activities that are enrolled at an elementary school with semi-rural characteristics in Kirikkale Provincial center were monitored for 2 years after a variety of protective applications. Materials and Methods: Three hundred and twenty-two children at the age of 7-11 were included in this study. Children were grouped as follows according to their cavity experiences and applications done: Group 1 - control group (with or without cavities) - was given hygiene training only; Group 2 - with medium level cavity activity (2-4 cavities in average) - oral hygiene training + surface restoration applied; Group 3 - children with 2-4 cavities on average - oral hygiene training + professional flour gel applied; Group 4 - children with 2-4 cavities in average - oral hygiene training + flour gel applied with brush; Group 5 - children with extreme cavity activity (children with 5 or more cavities) - oral hygiene training + surface restoration + professional flour gel combination applied. Results: At the end of the 2nd year, 277 children were reached. The increase of number of cavities in permanent teeth was determined as 35%, 0%, 1%, 0%, and 7% in groups 1-5, respectively. The difference between groups was found to be significant (Chi-square analysis, Pearson Chi-square = 27.002, P < 0.01). Conclusion: These findings have showed that, in Kirikkale Provincial center, some cavity-preventive measures such as surface restoration and gel applications, along with hygiene training, could provide optimum protection for school-age children. © 2016 European Journal of Dentistry.Öğe Farklı Polisaj Sistem Ve Tekniklerinin Üç Farklı Kompozit Rezinin Yüzey Pürüzlülüğüne Etkisi(2013) Bayraktar, Yusuf; Doğan, Damla; Ercan, ErtuğrulAmaç: Bu in-vitro çalışmanın amacı üç farklı polisaj sisteminin yine üç farklı kompozit rezinin yüzey pürüzlülüğüne etkisini araştırmaktır. Ayrıca çalışmada polisaj sistemleri hem ıslak hem de kuru olarak kullanılmış ve polisaj sistemlerinin ıslak ve kuru olarak uygulanmasının yüzey pürüzlülüğüne etkisi araştırılmıştır. Gereç ve Yöntem: Çalışmada kullanılan üç farklı kompozit rezin grubunun (Photo Posterior, KURARAY, JAPONYA, Filtek Ultimate,3M ESPE, ALMANYA, Aelite LS Posterior, BISCO, ABD) her birisi için 10 mm çapında ve 2 mm yüksekliğinde teflon kalıplar kullanılarak otuzar adet örnek hazırlandı. Hazırlanan örnekler rastgele 6 alt gruba ayrıldı. (n5). Alt gruptaki örneklerden ilk üç grup kuru olarak farklı polisaj sistemleri ile polisajlandı.

Türksel; Soyman, Mübin; Dalli, Mehmet; Yildirim, IşılObjective: The purpose of this study was to investigate the clinical performance of high-strength glass ionomer cement (HSGIC) and resin-modified glass ionomer (RMGIC) in single and multiple surface carious cavities in the field conditions. Material and Methods: A split-mouth design, including ninety-one fillings placed on contra lateral molar pairs of 37 children, was used in permanent dentition. As filling materials, a HSGIC (Ketac Molar/3M ESPE) and a RMGIC (Vitremer/3M ESPE) were used with the Atraumatic Restorative Treatment (ART). Baseline and 6, 12 and 24-month evaluations of the fillings were made with standard-ART and USPHS criteria by two examiners with kappa values of 0.92 and 0.87 for both criteria. Results: According to the USPHS criteria, the retention rates of RMGIC and HSGIC restorations were 100% and 80.9% for single surface, and 100% and 41.2% for multiple surface restorations after 24 months, respectively. Irrespective of surface number, RMGIC was significantly superior to HSGIC (p=0.004), according to both standard-ART and USPHS criteria. Conclusion: The results indicate that RMGIC may be an alternative restorative technique in comparison to high-strength GIC applications in ART-field-trials. However, further clinical and field trials are needed to support this conclusion.Öğe Güneydoğu Anadolu kırsalında yaşayan çocuklarda değişik koruyucu uygulamaların değerlendirilmesi: 24 aylık saha çalışması sonuçları(2006) Dülgergil, Türksel; Soyman, Mübin; Civelek, Arzu; Ercan, Ertuğrul; Ercan, Okur MeryemSon yıllarda, değişik ülkelerde izlenen yaygın çürük azalımına rağmen, Türkiye gibi gelişmekte olan çoğu ülkelerde diş çürüğü hala önemli bir sağlık sorunu olarak devam etmektedir. Çok değişkenli bir hastalık olmasına rağmen, çürüğün kontrol altına alınmasındaki temel sorunlarda birisi de koruyucu-tedavi edici uygulamaların, toplumun değişik seviyelerine ulaştırılmasındaki güçlüğüdür. Bu çalışmada; dişhekimiiği hizmetinin sınırlığı olduğu Güneydoğu Anadolu kırsalındaki çocuklarda değişik koruyucu uygulamalar incelenmiştir. Diyarbakır kentine 55 kilometre uzaklıktaki Eğil ilçesi yatılı bölge okulu çalışma alanı olarak seçildi. Yaşları 9-17 arasında değişen toplam 120 çocuk 3 gruba ayrıldı. Bunlar; grup 1: cam-ionomer fissür örtücü gurup, grup 2: kontrol grubu ve grup 3: florjel grup. Tüm koruyucu uygulamalar okul ortamında ve bir grup dişhekimi ve dişhekimiiği öğrencisi tarafından gerçekleştirildi. İki hekim tarafından gerçekleştirilen ilk muayenenin sonrasında çocuklar ikinci yılın sonunda tekrar muayene edildi. Grup 1A 2 ve 3 için iki yıllık ortalama çürük artışı sırasıyla 00.07±0.6, 0.82±0.95, 0.68±0.75 olarak belirlendi. Gruplar arasındaki fark istatistiksel olarak anlamlı bulundu (p<0.0001). Sonuç olarak; sınırlı şartlara rağmen, ART yüzey örtücüler gibi basit koruyucu uygulamaların Güneydoğuanadolu uzak kırsalında yaşayan çocuklarda etkin olabileceği belirlendi.Öğe In vitro assessment of the effectiveness of chlorhexidine gel and calcium hydroxide paste with chlorhexidine against Enterococcus faecalis and Candida albicans(2006) Ercan, Ertuğrul; Dalli, Mehmet; Dülgergil, Ç.TürkselObjective: The purpose of this study was to compare the effectiveness of various medicaments, including Ca(OH)2/ 2% chlorhexidine, 2% chlorhexidine gel, and Ca(OH)2 alone, against Enterococcus faecalis and Candid albicans in vitro. Study design: Eighty extracted single-rooted human maxillary teeth were used. After removing the crown, each root was instrumented up to size 50 by using a conventional technique. The root canal was irrigated with ethylenediamine tetra-acetic acid (EDTA) solution to remove smear layer. Then, roots were infected with E faecalis and C albicans. Subsequently, the roots were divided into 4 treatment groups: group 1 was treated with calcium powder hydroxide in distilled water, group 2 was treated with calcium hydroxide powder in 2% chlorhexidine, group 3 was treated with 2% chlorhexidine gel, and group 4 was treated with 0.9% sterile saline serving as negative control. Microbial samples were taken after 7, 15, and 30 days. After incubation, dentine chips were obtained form each root canal and examined microbiologically. The microbiological samples were plated to count colony-forming units in per milligram of dentin. Results: The results showed that the 2% chlorhexidine gel was significantly more effective than calcium hydroxide with 2% chlorhexidine, calcium hydroxide, and control saline solution (P < .05). Conlusion: Under the conditions of this study, 2% chlorhexidine gel is effective in the elimination of E faecalis and C albicans from the root canal system. However, to support this in vitro observation, further in vivo studies are needed. © 2006 Mosby, Inc.

Methods: This study is based on an experiment conducted on 90 patients between November, 2002 and November, 2003 using a sampling. One hundred single root canals were microbiologically sampled from these patients by using sterile paper points. Among 100 canals sampled, 61 had primary infection and 39 had a history of secondary infection. Microorganisms were isolated and identified by using established advanced microbiologic techniques for anaerobic species. Results: A total of 197 cultivable isolates were recovered, the microbial findings in both types of canals, such as the number of species isolated, the 68.0% of Gram-positives and 27.9% gram-negatives, the 52.8% of facultative and 43.1 % strict anaerobic microorganisms 4.1% fungi and so on. Ten canals presented no microbial growth. Conclusions: The prevalence of bacteria and fungi found in 100 root canals is the prevalence of the microbial genera in primary and secondary endodontic infection. Peptostreptococcus spp was the most predominantly isolated microbial genera, followed by Streptococcus spp (14.2%), Porphyromonas spp (12.2%), E. faecalis (9.6%), Staphylococcus salivarius (8.6%), Prevotella spp (8.1%), Lactobacillus spp (7.1%), Actinomyces spp (7.1%), Candida albicans (4.1%), Fusobacterium spp (3.6%) Veillonella spp (2.5%), Eubacterium spp (2.5%), Bacillus spp (2.0%), and Escherichial coli (1.6%) were other types of bacteria recovered. © 2006 Taylor and Francis Group, LLC.Öğe One-year clinical evaluation of Quixfil and Gradia Direct composite restorative materials in posterior teeth(2013) Doğan, Damla; Ercan, Ertuğrul; Hamidi, Mehmet Mustafa; Aylıkçı, Bahadır Uğur; Çolak, HakanThe 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.Öğe Prevention of maternal bacterial transmission on children's dental-caries-development: 4-year results of a pilot study in a rural-child population(Pergamon-Elsevier Science Ltd, 2007) Ercan, Ertuğrul; Dülgergil, C. Türksel; Yildirim, Isil; Dalli, MehmetAim: Dental caries with its bacterial agent is an infectious disease, and shows a vertical transmission. The control of bacterial transmission of Mutans streptococci (MS) from mother to child has been studied, and its results on their children's caries development, and on their siblings' bacterial levels, have been analysed in a field-trial (for 4 years) in rural area. Material and methods: In the same tribe, 8 mothers and their 11 children (test children [TC]), and then (following years) their 9 siblings (test sibling [TSb]), were followed for 4 years. The study started when the TC group had just started to erupt. Test mothers were subjected to a preventive regime. Examination of caries development as well as determination of plaque levels of MS in TC and TSb were carried out annually and at 6-month intervals. At the end of 4 years, two control groups (control children [CC] and control siblings [CSb]) resembling TC and TSb were selected from the other tribe living in the same village, and bacterial data and caries status were compared to both test groups. Results: Microbial data demonstrated that the test children (p < 0.01) and test siblings (p < 0.05) had significantly low bacterial level in plaque samples. Accordingly, TC had significantly low dmf-t and -s number compared to corresponding control group (p < 0.001 for dmf-t, p < 0.0001 for dmf-s). Conclusion: The preventive regimen was applicable in rural southeastern Anatolia, where an introverted life style with a great tribal system is prevailing, any other preventive measures may have been practical or available, and babies are basically cared by mothers.
