Öğe Antibacterial efficacy of prophylactic ozone treatment on patients with fixed orthodontic appliances(2013) Aykut-Yetkiner A.; Eden E.; Ertugrul F.; Ergin E.; Ateş M.Objective. This study investigated the efficacy of ozone on microflora of patients with fixed orthodontic appliances. Materials and methods. Ten subjects undergoing fixed appliance therapy were enrolled in the study. Before any application, two elastic ligatures were removed with the aid of a sterile probe from the premolar brackets on the upper right and lower left jaws for baseline bacteriological counts. Then ozone gas was applied for 180 s by running the device on prophylaxis mode with included mouth tray according to the manufacturer's recommendations on all brackets. After the ozone application, two other elastic ligatures were removed from the opposite sides of the mouth of the patients. One week after the application two more elastic samples, which were not changed in the previous session, were collected from the upper right and lower left premolar brackets. The elastic ligatures were immersed in transfer solutions and cultured to determine the Streptococcus mutans and Lactobacillus acidophilus. Statistical analysis of the data was obtained by paired Student's t-tests. Results. The ozone treatment reduced the S. mutans and L. acidophilus immediately after the application and these reductions were found to be statistically significant (p = 0.038 and p = 0.020). Both the S. mutans and L. acidophilus values increased by the 1-week period and the S. mutans values were significantly higher than the baseline values (p = 0.01). Conclusion. It can be concluded that the ozone treatment may have an instantaneous lethal effect on S. mutans and L. acidophilus; however, within the limitations of this study, a long-term preventive effect could not be observed. © 2013 Informa Healthcare.Öğe Atypical presentations of pediatric actinomycosis: Report of a case(2002) Sezer B.; Ertugrul F.; Günbay S.; Basdemir G.; Öztop F.It is well recognized that cervicofacial actinomycosis is rare in children especially at maxilla. Actinomycosis involving the maxilla usually is seen as a localized intraoral infection in contrast to classical cervicofacial actinomycosis. In this article, we describe an 8-year-old patient who had actinomycosis involving the bone at the left maxillary lateral incisor region. The diagnosis was based on histologic report because of location and development of the lesion with unusual history. The treatment of choice was removal of the soft and hard tissues with concomitant prolonged penicillin administration. In cases of persistent oral infection the diagnosis of actinomycosis should be actively attempted through microbiologic and histologic examination.Öğe Biocompatibility of glass ionomer cements with and without chlorhexidine(2013) Iz S.G.; Ertugrul F.; Eden E.; Gurhan S.I.D.Objective: The aim of the present study is to evaluate the biocompatibility of glass ionomer cements (GICs) with and without chlorhexidine (CHX) as well as coated with varnish or not using in vitro cytotoxicity test. Materials and Methods: Biocompatibility of Fuji IX, Fuji IX with varnish, Fuji IX with 1% CHX diacetate and Fuji IX with 1% CHX diacetate with varnish was determined with in vitro cytotoxicity assay by using L929 mouse connective tissue fibroblasts. After 72 h, cell viabilities were evaluated by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay to determine the effects of the cements on the mitochondrial function and microscopic images were taken by scanning electron microscopy. Results: Statistical analysis was performed by one-way analysis of variance followed by the Bonferroni post-hoc test at a significance level of P < 0.05. 72 h after treatment, there were statistically significant differences between Fuji IX and Fuji IX-CHX (P < 0.001). In addition, the reduction of the cytotoxicity by coating the GICs with varnish was indicative and increased the cell viability ratio (P < 0.001). Conclusions: Fuji IX coated with varnish was found to be the most biocompatible one among others. Thus adding CHX significantly reduced the cell viability, it is assumed that, due to the leakage of CHX and the other components of the GICs to the cell culture medium, the cell viabilities were decreased, so it is highly recommended to use varnish not only to reduce the water loss from the GICs, but also to reduce the cytotoxicity of the GICs. © 2013 Dental Investigations Society.Öğe Color assessment after bleaching with hydrogen peroxide versus ozone: A randomized controlled clinical trial(Academy of General Dentistry, 2017) Aykut-Yetkiner A.; Ertugrul F.; Eden E.; Aladag A.; Ergin E.; Ozcan M.This randomized controlled clinical trial evaluated the color change of teeth bleached with either hydrogen peroxide (HP) or ozone (OZ). A total of 26 patients with a mean age of 36.2 years (SD, 8.7 years) who met the inclusion criteria were enrolled in the study. The subjects were randomly assigned to receive chairside bleaching using 40% HP or gaseous OZ. Maxillary dental arch vacuum trays were constructed with circumferential openings in the middle portion of the maxillary incisors at their labial surfaces. These trays were used for measuring color-first at baseline and then immediately and 48 hours after postbleaching-and were not used in bleaching. Changes in color were determined using CIE L*a*b*coordinates. Analysis of the data revealed that, while overall color change (E*) values of the HP and OZ groups did not show statistically significant differences immediately after bleaching (P = 0.114), E*values were significantly different 48 hours postbleaching (P = 0.00). Visible color changes were not obtained with either HP or OZ immediately postbleaching. The greatest visible color change occurred with HP 48 hours postbleaching. © 2017 by the Academy of General Dentistry.Öğe Combined apexification and orthodontic extrusion of a hypoplastic permanent canine(2007) Cogulu D.; Han B.; Yetkiner E.; Ertugrul F.Localized infection in the primary teeth was reported as an etiological factor in the formation of a hypoplastic defect in the underlying permanent teeth. The purpose of this report is to present the case of a 10-year-old girl with an unusual local hypoplasia in the mandibular left permanent canine and emphasize the importance of multidisciplinary management, including combined apexification and orthodontic extrusion. The 12-month recall examination revealed no pathology associated with the rehabilitation, and the patient's esthetic and functional expectations were satisfied.Öğe A comparative study of plaque mutans streptococci levels in children receiving glass ionomer cement and amalgam restorations(2003) Ertugrul F.; Eltem R.; Eronat C.Purpose: The restorative materials amalgam (Standalloy F) and glass ionomer cements (Chelon Silver) were comparatively investigated to determine the number of mutans streptococci. Methods: Saliva and plaque were collected from patients before and 40 days after the insertion of their restorations. Results: Total bacteria and mutans streptococci counts were found to be statistically significantly reduced when compared with the prerestoration counts in the saliva samples (P<0.001). Microbiological analysis of the dental plaque showed that the number of mutans streptococci in the glass ionomer cements was significantly lower than in the amalgam restorations (P<0.001). Conclusions: This study showed that silver glass ionomer cements inhibited the growth of mutans streptococci.Öğe Comparison of conventional versus colored compomers for class II restorations in primary molars: A 12-month clinical study(2010) Ertugrul F.; Cogulu D.; Özdemir Y.; Ersin N.Objective: To evaluate the 12-month clinical performance of conventional (Compoglass F) and colored (Twinky Star) compomer restorative materials in class II restorations of primary molars. Materials and Methods: A total of 196 restorations were placed in 98 children aged between 5 and 10 years (mean age: 7.43 ± 1.31 years) who had bilateral matched pairs of carious posterior class II primary molars. A split-mouth design was used in which 2 materials (Compoglass F, Twinky Star) were randomly placed on contralateral sides by 3 dentists. At baseline, after 6 and after 12 months, the restorations were evaluated using modified US Public Health Service criteria for: secondary caries, marginal integrity, marginal discoloration, anatomic form and surface texture. The Alpha and Bravo scores were considered as clinical success. The data were subjected to statistical analysis by the Wilcoxon and McNemar tests (p < 0.05). The Kaplan-Meier survival method was applied to estimate survival percentages. Results: No significant difference was found among the groups at all recalls regarding marginal integrity, marginal discoloration, anatomic form, secondary caries and surface texture. The 12-month mean cumulative survival rate of Compoglass F was 95.7%, while in the Twinky Star group, the survival rate was 93% in class II restorations with no significant difference between the groups for either material. Conclusion: Both conventional and colored compomer materials are suitable restorative materials for primary teeth for at least 12 months. Colored compomers could also be a good alternative to tooth-colored compomers in the restoration of primary molars. © 2010 S. Karger AG, Basel.Öğe Dental management of a patient with oculo-facio-cardio-dental syndrome(2008) Cogulu D.; Ertugrul F.Oculo-facio-cardio-dental (OFCD) syndrome is an X-linked dominant syndrome characterized by congenital cataract, microphtalmia, secondary glaucoma, long narrow face, high nasal bridge, pointed nose with cartilages separated at the tip, cleft palate, atrial septal defect (ASD), ventricular septal defect (VSD), radiculomegaly, delayed eruption, oligodontia, and persistence of primary teeth. The aim of this report is to indicate the importance of early diagnosis and management of oculo-facio-cardio-dental syndrome.Öğe Effect of chewing gum on plaque acidogenicity(2000) Koparal E.; Ertugrul F.; Sabah E.The aim of this investigation was to study the effect of chewing sucrose-containing gum, xylitol-sorbitol-containing gum and natural gum (Pistacia lenticus) on the pH recovery of sucrose challenged dental plaque. Plaque pH was measured by microtouch electrode method on two-days old plaque. The results of the present study suggest that the chewing gum increases plaque pH. Chewing natural gum created the highest plaque pH values.Öğe Evaluation of high risk university students' knowledge about dental trauma and emergency procedures(University of Dicle, 2013) Ersin N.; Ertugrul F.; Oncag O.; Menderes M.; Uzel I.Dental trauma is a common consequence of sports practice in individuals competing in all levels of sports. The aim of this study was to evaluate the level of knowledge of dental trauma and emergency procedures among university students attending to School of Physical Education and Sports. A questionnaire was carried on 95 students with a mean age of 23.8 years. The questionnaire surveyed concepts, experiences and behaviors after dental trauma, the knowledge of immediate emergency management and the use of mouthguard. A total of 35.8% students had experienced dental trauma. Most commonly encountered dental trauma was uncomplicated crown fracture (%52.9) and 67.6% of the subjects who experienced dental trauma applied for treatment. Only 34.7% of the students were aware that the avulsed tooth should be reimplanted and 6.3% knew that the avulsed tooth should be maintained in a liquid such as milk, water or mouth. Although most of the students were aware of the possibility of accidents during sports practice, only 8.4% reported to use a mouthguard. This study showed a lack of knowledge in students possesing high risk factors for dental trauma, thus reinforcing the need for educational programmes to improve the knowledge of dental trauma and use of mouthguards.Öğe Fluoride levels in breast milk and infant foods(Journal of Clinical Pediatric Dentistry, 2000) Koparal E.; Ertugrul F.; Oztekin K.The aim of the present study is to determine the fluoride concentrations of breast milk, several milk formulations, cow's milk and yogurt shake in a nonfluoridated area, in order to estimate the fluoride intake of infants and evaluate fluoride supplementation suggestions. Breast milk samples were collected from 57 lactating mothers. Ten brands of milk formulations, 9 different brands of cow's milk and 3 brands of yogurt shake were purchased from the market. Fluoride concentrations of the samples were analyzed using a specific fluoride electrode. The average fluoride level was 0.019±0.004 ppm in breast milk, 0.022±0.007 ppm in cow's milk and 0.022±0.003ppm in yogurt shake. Fluoride levels of milk formulations prepared by distilled water were ranging between 0.118 to 0.021 ppm. It is concluded that in non-fluoridated areas, fluoride intake of infants from the above sources is not very high and fluoride supplements may be prescribed.Öğe Infraclusion of primary molars: A review and report of a case(2002) Ertugrul F.; Tuncer A.V.; Sezer B.The term infraclusion is usually used to define mandibular primary teeth in posterior region that remain below the occlusion level. The degree of infraclusion depends on some factors like deviation below the occlusal plane, and infraclusion of tooth in the alveolar bone. Deficient eruptive force, disturbed metabolism of the periodontal ligament, trauma, local inflamation, deficient local vertical bone growth, disturbance in interaction between normal resorption and hard tissue repair, ankylosis and hereditary components have been given as etiological factors. Complications of infraclused primary molars are tipping of the neighboring teeth, space loss, supraeruption of the antagonists, and dislocations of permanent teeth lying under the primary tooth. In this case report, after reviewing the literature, a patient with infraclused mandibular primary second molar has been examined to observe the complications of infraclusion. With an appropriate treatment approach, a proper condition was prepared for the eruption of permanent teeth.Öğe Plaque accumulation and inflammation adjacent to restorations of amorphous calcium phosphate-containing composite in early childhood caries(Quintessence Publishing Co., Ltd, 2018) Gürlek C.; Ertugrul F.; Nile C.; Lappin D.F.; Buduneli N.Purpose: To evaluate the clinical, biochemical, and microbiological reactions to nanocomposite containing amorphous calcium phosphate (ACP) in comparison to a traditional composite restorative material in early childhood caries. Materials and Methods: Eighteen teeth were restored with the test material (ACP-containing resin) and 18 teeth were restored with the control material (traditional composite, TC) in fourteen paediatric patients using a splitmouth design. One caries- and restoration-free intact tooth in each patient was selected as the healthy control. Gingival crevicular fluid (GCF) and supragingival plaque samples were collected at baseline before the treatment and also on days 1, 7, 14 and 30 after treatment. Unstimulated whole saliva samples were obtained from each patient at baseline, and 1 and 6 months after restoration. GCF and saliva samples were assayed for IL-17A, IL-17F IL- 17A/F, IL-17E, OPG and RANKL levels by ELISA, and plaque composition was assessed using RT-PCR. Results: Clinical evaluation indicated no statistically significant differences between the two restorative materials according to the FDI criteria surface lustre, material retention and marginal adaptation properties. Pro-inflammatory IL-17 levels decreased statistically significantly at 6 months compared to baseline and 1-month values (p < 0.05). The baseline pro-inflammatory IL-17 cytokine levels in GCF samples around the carious teeth were higher than those obtained around the healthy teeth (p < 0.05), but similar in GCF from the ACP-test and TC teeth. Microbiological findings were similar in the ACP and T groups. Conclusion: It may be suggested that both ACP-containing and traditional resin composites show similar antimicrobial and biochemical effects in early childhood caries. © Quintessenz.Öğe Supernumerary primary tooth with facial and palatal talon cusps: A case report(2008) Topaloglu Ak A.; Eden E.; Ertugrul F.; Sütekin E.Talon cusp is a tooth anomaly originating from the tooth's lingual surface in most cases. To date, very rare cases have been reported documenting talon cusps both on the facial and palatal surface of an affected tooth in the dental literature. The purpose of this case report was to describe the facial and palatal talon cusps on an ectopic supernumerary primary maxillary tooth. A micro-CT investigation indicated no pulpal extensions within facial and palatal talon cusps.Öğe An unusual case of hypodontia with extensive caries: a multidisciplinary treatment approach.(1991) Eronat N.; Ertugrul F.[No abstract available]
