Öğe Comparison of inferior alveolar nerve block and intraligamentary anesthesia on the discomfort of children(2012) Tekin U.; Ersin N.; Oncag O.; Bent B.; Menderes M.; Kocanali B.Intraligamentary anesthesia(ILA) can be an alternative to inferior alveolar nerve block(IANB) for the extraction of primary molars. To evaluate the effects of ILA and IANB on the discomfort of children during the extraction of mandibulary first primary molars. A single-blind, randomized split mouth study. Twenty-nine healthy children participated in this study. Dental Subscale of Children's Fear Survey Schedule(CFSS-DS) was used to evaluate the dental fear of children. Visual analog scale(VAS) scores of both ILA and IANB groups were recorded during the injection procedure. Heart rate values were recorded during the injection, decollement and extraction periods. Pain perceptions of children were evaluated with sound, eye and motor (SEM) scale by two trained observers during the injection and extraction procedures. The mean CFSS-DS score (22.86±5.829) did not indicate significant dental fear. Altough VAS scores of IANB was higher than ILA, there was no statistically significant difference between them (p>0.05). A significant higher mean SEM score for IANB group was recorded in comparison to ILA during both injection and extraction periods (p<0.05). There were no statistically significant differences in heart rate during different procedures between two groups (p>0.05). Statistical analyses were performed using the SPSS 18.0 for Windows. Chi Square test, variance analysis and Wilcoxon signed ranks tests were used. ILA provides effective local pain control and may be an alternative method especially for children.Öğe The Correlation between Serum Immunoglobulin A and Immunoglobulin G Levels and the Presence of Treponema denticola in Human Periapical Lesions(2007) Cogulu D.; Oncag O.; Kutukculer N.; Uzel A.; Eronat C.The aim of this study was to compare the serum immunoglobulin A (IgA) and immunoglobulin G (IgG) levels and the presence of Treponema denticola in the root canals in a group of teeth with/without periapical lesion. A total of 66 children aged 8 to 13 years old were involved in this study. Five milliliters of blood samples were taken to detect the serum IgA and IgG levels. Sixty-six endodontic samplings were also obtained to determine the presence of T. denticola by polymerase chain reaction. The presence of T. denticola between the groups with/without periapical lesion was statistically significant (p = 0.026). A significant negative correlation was found between serum IgG and IgA levels and the presence of T. denticola (p = 0.023 and 0.038, respectively). This study may support the hypothesis that the presence of T. denticola in the root canals is mainly related to the periapical lesions, and the higher levels of serum IgG and IgA levels may protect against T. denticola. © 2007 American Association of Endodontists.Öğe Cytotoxic effects of primary tooth root canal filling materials on L929 cell line(2010) Sarigol C.G.; Cogulu D.; Oncag O.; Deliloglu I.G.Purpose: The purpose of this study was to determine the cytotoxic effects of five different, primary tooth root canal filling materials on L929 permanent cell line with MTT assay. Methods: Kri 1 paste (iodoform), Diapex (iodoform+Ca(OH)2), Metapaste (Ca(OH)2 with distilled water), Dentalis (iodoform+ZOE+Ca(OH)2) and Kalsin (Ca(OH) 2 with glycerin) were used in this study. Tested materials were in contact for 24, 48 and 72 hours with L929 cells. At the end of the test periods, MTT test solutions were added to the plates and incubated for 3 hours at 37°C. Then optic densities were read using UV visible spectrophotometer. All assays were repeated three times to ensure reproducibility. The obtained data were analyzed statistically by one-way analysis of variance and Dunnett T3 post hoc test (P<0.05). Results: All tested materials were found cytotoxic on L929 cell line. It was found that Kri 1 paste group showed the highest survival rates. Conclusions: We concluded that the use of Kri 1 paste as a root canal filling material is a better option than other medications in primary teeth. Further research is necessary to determine the effect of root canal filling materials on vital tissues.Öğe Dysosteosclerosis: A case with unique dental findings and SEM evaluation of a hypoplastic tooth(1999) Oncag O.; Özkınay, Ferda; Eronat C.A ten-year-old boy, who had the typical dental findings of dysosteosclerosis such as yellowish, hypoplastic teeth, retarded eruption, which upon eruption, decayed rapidly, is presented. To date this is the first known case reported with a congenital absence of the first permanent molars. Furthermore, SEM evaluation of the enamel and dentin was performed on a tooth from a patient with dysosteosclerosis for the first time. These studies showed weak ultrastructural compositions due to irregular calcification.Öğe Efficacy of propolis as an intracanal medicament against Enterococcus faecalis(2006) Oncag O.; Cogulu D.; Uzel A.; Sorkun K.This study sought to compare the antibacterial efficacy of three commonly used intracanal medicaments with propolis against Enterococcus faecalis. This study utilized 180 freshly extracted single-rooted intact human permanent teeth with a single root canal. After root canal preparations and sterilization, canals were contaminated with E faecalis and incubated at 37°C (±1.0°C) for seven days. The teeth were divided randomly into six groups. To determine bacterial growth on blood agar, microbiological samples were carried out with sterile paper points to evaluate results at 48 hours and at ten days. All data were analyzed statistically with t-test, Mann Whitney, Kruskal Wallis, and one-way ANOVA tests. This study revealed that propolis had good in vitro antibacterial activity against E faecalis in the root canals, suggesting that it could be used as an alternative intracanal medicament.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 Kabuki syndrome with additional dental findings: A case report(2008) Cogulu D.; Oncag O.; Celen E.; Özkınay F.Kabuki Syndrome (KS) is a multiple congenital anomalies/mental retardation syndrome of unknown etiology. It is characterized by a dysmorphic face, postnatal growth retardation, skeletal abnormalities, mental retardation, and unusual dermatoglyphic patterns. The characteristic dental findings include hypodontia, microdontia, absence of upper lateral and lower central incisors and upper molars, abnormal tooth shape, widely spaced teeth, ectopic upper molars and malocclusion. The purpose of this report is to describe common and additional dental findings and dental treatment of an 11-year old female patient with KS. This case report emphasises the importance of oral and dental manifestations for diagnosis.Öğe Management of a case with bilateral talon cusp in primary dentition(2006) Cogulu D.; Oncag O.The talon cusp is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case and should be as conservative as possible. The purpose of this report was to present the case of bilateral talon cusp in primary maxillary central incisors that was successfully managed with conservative therapy.Öğe Microbiological evaluation and antibiotic susceptibility of dental unit water systems in general dental practice.(2008) Uzel A.; Cogulu D.; Oncag O.OBJECTIVE: The microbial quality of water in a dental unit water systems (DUWS) is of considerable importance because patients and dental staff are regularly exposed to water and aerosol generated from the dental units. The objective of this study was to evaluate the 20 DUWS in general dental practices and to determine the antibiotic susceptibility of the colonizing bacteria. METHODS: Three water and one biofilm samples from each DUWS were investigated for total viable count (TVC), oral streptococci, Pseudomonas spp., Enterobacteria, Candida albicans and Legionella pneumophila. RESULTS: A total of 44 morphologically different colonies were obtained from water samples and 20 types of colonies (45.5%) could be identified using API test strips. The mean TVC values were 4.36 log CFU ml(-1) for source waters, 4.95 log CFU ml(-1) for 3-in-1 syringe samples, 4.91 log CFU ml(-1) for air rotor samples and 3.66 log CFU cm(-2) for biofilm samples. Susceptibilities of the isolates were tested against piperacillin, ampicillin, ceftazidime, meropenem, gentamicin, tetracycline, ofloxacin and chloramphenicol by using microdilution method according to NCCLS. The meropenem and ofloxacin have shown the broadest spectrum against to the tested isolates. CONCLUSION: The study emphasizes the need for effective mechanisms to reduce the microbial contamination in DUWS, and highlights the risk for cross-infection in general dental practice.Öğe PCR-based identification of selected pathogens associated with endodontic infections in deciduous and permanent teeth(2008) Cogulu D.; Uzel A.; Oncag O.; Eronat C.Objective: The aim of the present study was to evaluate the presence of the selected pathogens in samples from deciduous and permanent tooth root canals by using PCR method and to determine the association of these organisms with clinical symptoms. Study design: A total of 145 children, 5 to 13 years old, were involved in this study. The presence of selected pathogens (Actinomyces israelii, Candida albicans, Enterococcus faecalis, Fusobacterium nucleatum, Porphyromonas endodontalis, Porphyromonas gingivalis, Prevotella intermedia, Streptococcus intermedius, Treponema denticola, Parvimonas micra, Tannerella forsythensis, Enterococcus faecium, Prevotella melaninogenica) in infected root canals was studied using PCR. Results: T. denticola (P = .012, .02) and E. faecalis (P = .012, .04) were highly associated with periapical radiolucency and previous pain, while P. gingivalis was associated with tenderness to percussion in both deciduous and permanent teeth (P = .01, .015). Conclusion: The results of the present study confirm that certain species of microorganisms are associated with clinical signs and symptoms of endodontic disease in both deciduous and permanent teeth. © 2008 Mosby, Inc.

The upper right first primary molar was extracted because of a periapical abscess and examined scanning electron microscopically. The aim of this article is to discuss the clinical and ultrastructural features of the anomally and revise the other odontodysplasia cases reported in the literature.Öğe Salivary Streptococcus mutans, Lactobacilli levels and buffer capacity in children with esophageal burns(2000) Oncag O.; Riza Alpoz A.; Eronat C.Children with esophageal burns due to toxic ingestion are medically compromised in many ways. They have problems like strictures in esophagus, dysphagia, gastroesophageal reflux and necessity to be fed with a special soft diet. Taking these distinctive features into consideration, we aimed to study these children with special focus on the dental caries risk. The experimental group consisted of 33 children between 2 and 14 years old (mean age 6.42 ± 0.56) who had received stricture treatment in the Pediatric Surgery Department of our university. The control group consisted of 20 healthy children aged between 3 and 14 (mean age 7.25 ± 0.7) who applied to the Pedodontics department for dental treatment. While mean dfs (± SE) was 11.13 ± 2.30 and mean DMFs (±SE) was 9.79 ± 4.76 in the experimental group, mean dfs (± SE) was found as 11.53 ± 2.16 and mean DMFS (± SE) was 1.90 ± 0.56 in control group. For the determination of Streptococcus mutans (SM), Lactobacilli (LB) and Buffer capacity (BC), salivary tests of Dentocult SM (Vivacult SM Vivadent-Liechtenstein), Dentocult LB (Vivacult LB-Vivadent - Liechtenstein) and Dentobuff (Vivacult BC- Vivadent-Liechtenstein) were applied to both groups. Our findings were evaluated statistically and compared by the Mann Whitney Confidence Test. The amount of Streptococcus mutans, Lactobacilli and the level of buffering capacity in the children with esophageal burns showed a high caries risk. Positive correlations were found between SM and LB, SM and dfs, LB and dfs levels and DMFs and duration of stricture treatment (p<0.05). However, negative correlations were found between BC and DMFs, DMFs and tooth brushing habit, dental visit and DMFs (p<0.05). The mean DMFs, LB and SM levels were lower and BC levels were higher in the control group. Although a significant difference was found between DMFs scores (p<0.05), no significant difference was found between LB, BC, SM and dfs levels (p>0.05). It could be concluded that children with esophageal burns have high dental caries risk and for this reason parental counseling about oral hygiene, diet, dental plaque controlling and preventive dental regimens have an importance in these medically compromised children.
