Publication Metadata only Spiral computed tomographic demonstration of C-shaped canals in mandibular second molars(BRITISH INST RADIOLOGY, 2005) MUMCU, GONCA; Cimilli, H; Cimilli, T; Mumcu, G; Kartal, N; Wesselink, PObjectives: The aim of this study was to evaluate the prevalence of C-shaped canals in single rooted mandibular second molars with spiral computed tomographic imaging in detail. Methods: One hundred and twelve single-rooted mandibular second molar samples were selected from 491 extracted mandibular second molars. The teeth were scanned by spiral computed tomographic technique to examine canal configurations. Results: The evaluation criteria of the shape of roots was based on Manning's category as round, oval and C-shaped. The prevalence of C-shaped canals was found to be 8. 1 % in mandibular second molars. The evaluation of the root canal configurations of C-shaped mandibular second molars with single roots (40 teeth) was based on Vertucci's classification. Vertucci type 1 canals were most frequently seen in C-shaped mandibular second molars (40%). Additionally, we disclosed three additional canal types. Conclusion: Results of this study demonstrated that high resolution visualization of the root canal shape can be achieved by spiral computed tomographic imaging.Publication Metadata only Clinical and immunological effects of azithromycin in Behcet's disease(WILEY, 2005) MUMCU, GONCA; Mumcu, G; Ergun, T; Elbir, Y; Eksioglu-Demiralp, E; Yavuz, S; Atalay, T; Direskeneli, HBACKGROUND: The aim of this study was to evaluate the effects of azithromycin on mucocutaneous manifestations, oral health and immune response in Behcet's disease (BD). METHODS: Eight BD patients with active mucocutaneous symptoms were treated with azithromycin for 4 weeks. Oral health, clinical manifestations and in vitro interleukin (IL)-12, interferon (IFN)-gamma, IL-10 and monocyte chemotactic protein (MCP)-1 responses were evaluated before and after treatment. RESULTS: The number of folliculitic lesions, healing time of oral ulcers and scores of plaque indexes (PLIs) were lower after azithromycin treatment (P < 0.05). Scores of PLIs correlated positively with the healing time of oral ulcers (P = 0.02). Although a trend towards increased stimulated IL-10 responses with azithromycin was observed, no statistically significant difference was found. Stimulated and unstimulated MCP-1, IFN-gamma and IL-12 responses were similar before and after treatment (P > 0.05). CONCLUSION: Azithromycin was observed to be effective in decreasing folliculitic lesions and fastening the healing time of oral ulcers in BD.Publication Metadata only Prevalence and distribution of oral lesions: a cross-sectional study in Turkey(BLACKWELL MUNKSGAARD, 2005) MUMCU, GONCA; Mumcu, G; Cimilli, H; Sur, H; Hayran, O; Atalay, TOBJECTIVES: The purpose of this study was to evaluate the prevalence and distribution of oral lesions (OLs) in Turkish population. SUBJECTS AND METHODS: In this cross-sectional study, 765 residents (F/M: 375/390) were selected by the cluster sampling method and examined according to WHO criteria. RESULTS: Excessive melanin pigmentation (6.9%) was the most common lesion in the study population. The tongue lesions observed in this study were as follows: fissured tongue (5.2%), varices (4.1%), hairy tongue (3.8%), geographic tongue (1.0%), atrophic tongue papillae (0.7%) and ankyloglossia (0.3%). The denture-related lesions were denture stomatitis (4.3%), suction irritation (0.8%), denture hyperplasia and torus palatinus as bony lesion (0.5%) and traumatic ulcers (0.3%). In regression analysis, being 65 years old and over was found as a statistically significant risk factor for the occurrence of pigmentation, fissured tongue, varices, hairy tongue, denture stomatitis and petechiae (P < 0.05). CONCLUSIONS: Pigmentation, fissured tongue and denture stomatitis were observed to be the most common lesions in Turkish population. Elderly population was a significant risk factor for occurrence of some OLs.Publication Metadata only TCR gamma delta (+) T-cell response to streptococcal antigens in patients with psoriasis(SPRINGER, 2005) MUMCU, GONCA; Ergun, T; Eksioglu-Demiralp, E; Direskeneli, H; Mumcu, G; Gurbuz, OPublication Metadata only Oral health related quality of life is affected by disease activity in Behcet's disease(WILEY, 2006) MUMCU, GONCA; Mumcu, G; Inanc, N; Ergun, T; Ikiz, K; Gunes, M; Islek, U; Yavuz, S; Sur, H; Atalay, T; Direskeneli, HOBJECTIVES: This study aimed to investigate oral and general health related quality of life (QoL) in patients with Behcet's Disease (BD) and to assess the performance of Turkish versions of oral health related quality questionnaires. SUBJECTS AND METHODS: Ninety-four BD patients, 24 patients with recurrent aphthous stomatitis (RAS), 113 healthy controls (HC) and 44 dental patients were investigated. QoL was assessed by oral health impact profile-14 (OHIP-14), oral health related quality of life (OHQoL) and short form-36 (SF-36) questionnaires. RESULTS: OHQoL, OHIP-14 and SF-36 subscale scores were significantly worse in patients with BD compared with those in HC (P < 0.05). Both OHIP-14 and OHQoL scores were significantly worse in active patients compared with inactives in BD and RAS (P < 0.05). Scores of SF-36 Role physical, Role emotional and Vitality were also lower in active patients than in inactives in BD (P < 0.05). Scores of OHIP-14 and OHQoL were significantly worse in patients treated with colchicine compared with those treated with immunosuppressives (P < 0.05). CONCLUSIONS: Both oral and general QoL was impaired in BD and associated with disease activity and treatment modalities. Translated Turkish versions of OHIP-14 and OHQoL were also observed to be valid and reliable questionnaires for further studies.Publication Open Access The close association between dental and periodontal treatments and oral ulcer course in behcet's disease: a prospective clinical study(WILEY-BLACKWELL PUBLISHING, INC, 2009-03-05) MUMCU, GONCA; Karacayli, Umit; Mumcu, Gonca; Simsek, Ismail; Pay, Salih; Kose, Osman; Erdem, Hakan; Direskeneli, Haner; Gunaydin, Yilmaz; Dinc, AyhanThe aim of the study was to evaluate the influence of dental and periodontal treatments to the course of oral ulcers in patients with Behcet's disease (BD). Fifty-eight consecutive BD patients with oral ulcers were studied. Twenty-nine patients were in the intervention group (F/M: 15/14, mean age: 39.6 +/- 6.9 years) and 29 (F/M: 15/14, 39.4 +/- 10.6 years) were followed with a conventional treatment approach. In addition to oral hygiene education, dental and periodontal treatments were carried out in the intervention group, whereas the control group was only given oral hygiene education. Patients were evaluated in the pre-treatment observation period (1 month), treatment period (1 month) and 6 months after treatment. An increase in the number of new oral ulcers (4.1 +/- 3.5) was observed within 2 days during the treatment compared with 3-30 days during treatment month (2.3 +/- 1.2) (P = 0.002). However, 6 months after the treatment, the number of oral ulcers (1.9 +/- 1.5) was significantly lower compared with the pre-treatment observation (4.8 +/- 3.2) (P = 0.000) and treatment periods (6.4 +/- 2.3) in the intervention group (P = 0.05), whereas a similar oral ulcer presence was observed in the control group (2.8 +/- 2.4, 3.7 +/- 2.3 and 4.8 +/- 4.3, respectively) (P > 0.05). Dental and periodontal indices were also better in the intervention group during the 6-month follow-up. Our results suggest that, in BD patients, dental and periodontal therapies could be associated with a flare-up of oral ulcers in the short term, but may decrease their number in longer follow-up. They also lead to a better oral health.Publication Metadata only The assessment of oral health-related quality of life by factor analysis in patients with Behcet's disease and recurrent aphthous stomatitis(WILEY, 2007) MUMCU, GONCA; Mumcu, G.; Hayran, O.; Ozalp, D. O.; Inanc, N.; Yavuz, S.; Ergun, T.; Direskeneli, H.BACKGROUND: The aim of the study was to test multidimensional properties of oral health impact profile-14 (OHIP-14) in Behcet's disease (BD) and recurrent aphthous stomatitis (RAS) patients with active oral ulcers. METHODS: Ninety-six BD patients, 28 patients with RAS and 117 healthy controls (HC) were included in this study. In patients with active oral ulcers, the frequency and healing time of ulcers were recorded. Multidimensional properties of OHIP-14 were examined by factor analysis. RESULTS: Factor analysis revealed three subscales and explained 66.49% of overall variance in these patients with active oral ulcers. The score of Subscale 1 was positively correlated with the recurrence of oral ulcers per month (P = 0.037). Subscale 3 scores of the patients treated with colchicine were worse than those treated with immunosuppressives (P = 0.035). CONCLUSIONS: The factor structure of OHIP-14 was found to be reliable and sensitive to clinical parameters and treatment modalities in active patients.Publication Metadata only Financing of dental services in Turkey: Opinions and expectations of dentists, residents, and patients(WILEY, 2004) MUMCU, GONCA; Hayran, O; Mumcu, G; Sur, H; Yildirim, C; Soylemez, D; Atli, HObjectives: This study investigates the attitudes of dentists, residents, and patients on the financing of dental services in Turkey. Methods: In this descriptive study, randomly selected groups of 860 dentists, 641 patients, and 866 residents from 9 provinces of Turkey were interviewed. Their agreement on various statements on financing issues of dental services were recorded and analyzed. Results: Eighty-two percent of the dentists, 83.8 percent of the patients, and 76.4 percent of the residents agreed that governments should finance all dental services. The majority of the dentists (83.6%), patients (74.7%), and residents (84.4%) stated that patients should pay a copayment for their dental treatment. Conclusion: Survey results indicate that the current financing system of dental services in Turkey is not satisfactory either for the providers or for the users.Publication Open Access Oral health is impaired in Behcet's disease and is associated with disease severity(OXFORD UNIV PRESS, 2004-06-01) MUMCU, GONCA; Mumcu, G; Ergun, T; Inanc, N; Fresko, I; Atalay, T; Hayran, O; Direskeneli, HObjectives. This study aimed to investigate the oral health of Turkish patients with Behcet's disease (BD) and whether it is associated with the disease course. Methods. One hundred and twenty patients with BD, 35 patients with recurrent aphthous stomatitis (RAS) and 65 healthy Turkish controls (HC) were included in the study. Oral health was investigated by indices applied in a BD out-patient clinic. Results. The mean scores of plaque, sulcus bleeding and gingival indices, probing depth and the number of extracted teeth were observed to be higher in patients with BD and RAS compared to HC (P<0.05). In the linear regression analysis, plaque index score was associated with the presence of oral ulcers and male gender. An elevated plaque index score was observed to be a significant risk factor for increased severity score in patients with BD in the logistic regression analysis (P = 0.034). Conclusions. Oral health is impaired in BD and associated with disease severity. Improvement of the oral health of BD patients may affect their disease course, leading to a better prognosis.Publication Metadata only Factors affecting dental job satisfaction - A cross-sectional survey in Turkey(SAGE PUBLICATIONS INC, 2004) MUMCU, GONCA; Sur, H; Hayran, O; Mumcu, G; Soylemez, D; Atli, H; Yildirim, CIn this cross-sectional study, a randomly selected group of dentists (n = 855) from nine provinces of Turkey were interviewed for their levels of intrinsic, extrinsic, and overall job satisfaction. The proportion of overall job satisfaction was computed as the proportion of dentists who had mean general satisfaction scores greater than or equal to4 on a 5-point, Likert-type scale and was found to he 40.8% for the sample as a whole. The significant factors that affected overall satisfaction were age, the type of social insurance possessed, income level, the presence of dental auxiliaries, and the number of patients examined per day. Multivariate analysis of the data revealed that the type of social insurance, the amount of monthly income, and the number of patients examined per day were the most common and statistically significant predictors of intrinsic, extrinsic. and overall satisfaction in Turkish dentists.
