Item About Assessment of Carotid Artery Calcifications on Radiographs Response(2022) Cetin, Mehtap Bilgin; Sezgin, Yasemin; Yilmaz, Mediha Nur Nisanci; Secgin, Cansu Koseoglu; 35131087; AAC-5931-2020Item Evaluating Well-being Among Dental Students Using the Warwick-Edinburgh Mental Well-being Scale and the Relationship Between Mental Well-being and Socio-demographic Findings(2021) Cetin, Mehtap Bilgin; Sezgin, Yasemin; Akinci, Seray; Alptekin, Nilgun Ozlem; 0000-0003-4104-6462; G-1816-2014Objective: The present study aimed to measure mental well-being among dental students using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) and to investigate factors affecting well-being. Materials and Methods: Baskent University Faculty of Dentistry students were invited to participate in the study in 2019. The participants were asked to complete the WEMWBS and a questionnaire describing their demographic details, social background and lifestyle habits. Results: A total of 268 dental students (68% females) participated in the survey, with a response rate of 85%. The overall WEMWBS score of the study population was 48.18 +/- 9.6. Statistically significant differences in WEMWBS scores were detected between first- and fourth-year (p<0.001) students and between fourth- and fifth-year students (p<0.001). Male students (p<0.001) whose first choice was to attend the school of dentistry (p=0.024) and who pursued hobbies (p=0.001) or regular sports activities (p=0.001) had significantly higher WEMWBS scores than those who did not. Dental students' smoking status (p=0.630), living accommodation (p=0.71) or parents' education level did not affect WEMWBS scores significantly. Conclusion: The mental well-being of dental students was influenced by their year of study, gender, first choice of school and pursuit of hobbies or regular sports activities. Factors that may affect the mental well-being of students should be carefully considered, and strategies should be implemented to monitor and promote well-being during the students' academic career.Item Assessment of carotid artery calcifications on digital panoramic radiographs and their relationship with periodontal condition and cardiovascular risk factors(2020) Bilgin Cetin, Mehtap; Sezgin, Yasemin; Nisanci Yilmaz, Mediha Nur; Koseoglu Secgin, Cansu; 32996164Objective The main purpose of this study is to determine the presence of carotid artery calcification (CAC) detected on digital panoramic radiographs (DPRs) retrospectively and correlate the findings with cardiovascular risk factors including gender, age, smoking status, hypertension, diabetes, and hyperlipidemia, along with atherosclerotic cardiovascular disease and periodontal status. Methods This clinical study is registered at ClinicalTrials.gov as NCT04017078. DPRs, periodontal status and cardiovascular risk factors of 1,101 patients (576 males, 525 females) were evaluated. The patients were grouped based on whether CAC was detected in dental DPRs [CAC (+)] or not [CAC (-)]. Periodontal status was categorised as gingivitis, periodontitis, and gingivitis with reduced periodontium (periodontally stable patient). Results Out of 1,101 patients, whose mean age was 42.1 +/- 15.5 years and 525 (47.7%) were female, 34 (3.1%) were diagnosed with CAC on DPRs. No significant difference was observed between groups considering gender, hypertension, diabetes, hyperlipidemia, smoking, and periodontal status. Patients aged 40-55 years (n = 398, 36.15%) and patients older than 55 years (n = 222, 20.16%) were associated with CAC (odds ratio = 4.49, 95% confidence interval = 1.65-12.17,P = 0.003; odds ratio = 4.41, 95% confidence interval = 1.33-14.61,P = 0.015, respectively). Conclusion Among all parameters, only age exhibited significant correlation with an increased risk of carotid calcification. Further studies with prospective designs and larger study populations are needed.Item Comparison of Two Morphometric Linear Methods to Measure the Alveolar Bone Loss Induced by Experimental Periodontal Disease in Rats(2020) Cetin, Mehtap Bilgin; Sezgin, YaseminObjective: The aim of this study was to compare the direct and indirect linear morphometric measurements for the evaluation of alveolar bone loss after experimentally induced periodontitis in rats. Materials and Methods: Right mandibles of 30 Sprague Dawley rats were collected from a previous study which induced periodontitis using ligature model. In direct measurement group, the distance between cementoenamel junction and alveolar bone crest was evaluated by digital caliper and periodontal probe with a dental loop, whereas indirect group measurement was performed by an image analysis program on digital photographs. Results: The difference between groups was determined using Mann-Whitney U test. Average alveolar bone loss was 1.08 +/- 0.22 mm in direct measurement group and 1.19 +/- 0.33 mm inindirect measurement group. The variation between direct and in direct groups was not statistically significant (p>0.05). Conclusion: Based on the present result, it can be concluded that, direct morphometric analysis might be an essential alternative to indirect morphometric evaluations to measure alveolar bone loss after experimentally induced periodontitis in rats.Item Evaluating the Effects of a Topical Preparation with Dexpanthenol, Silbiol, Undecylenic Acid, and Lidocaine on Palatal Mucosa Wound Healing in a Rat Model(2019) Sezgin, Yasemin; Cetin, Mehtap Bilgin; Bulut, Sule; Alptekin, Nilgun Ozlem; Borcek, Pelin; 0000-0003-4104-6462; 30322831; G-1816-2014; AAC-5448-2020; AAC-5931-2020Background: Postoperative complications occur after periodontal plastic surgeries, but an ideal treatment to overcome them has not been found yet. Aims: To evaluate the effects of topically applied Oral-norm gel on the healing of excisional wounds. Study Design: Animal experiment. Methods: Excisional wounds with a diameter of 3 mm were made in the center of the palatal mucosa of 63 Sprague Dawley rats. Seven animals were sacrificed at time 0. The remaining rats were divided into two groups: a test group in which the topical Oral-norm gel was applied three times a day and a control group in which nothing was applied. Seven animals in each group were sacrificed at 3, 7, 14, and 21 days. Mean wound surface area was measured photographically, while wound healing and width were evaluated microscopically. Results: The mean wound surface area decreased significantly after 3 days in both groups (p<0.001). Between days 3 and 7, the mean wound surface area decreased from 6.62 (2.85) to 0.83 (1.62) mm 2 in the control group and 5.07 (0.88) to 1.42 (1.67) mm 2 in the test group. The wound width decreased significantly on day 7 in both groups (p<0.001), with no further changes by day 14. Both groups had a significant increase in inflammation and vascularization on day 3 (p<0.001), with a reduction thereafter. No significant differences in macroscopic and microscopic measurements were observed between the groups at any time point (p>0.05). Conclusion: The Oral-norm gel has no positive healing effects in the palatal mucosa of rats.Item Effects of self-ligating and conventional brackets on halitosis and periodontal conditions(2015) Kaygisiz, Emine; Uzuner, Fatma Deniz; Yuksel, Sema; Taner, Levent; Culhaoglu, Rana; Sezgin, Yasemin; Ates, Can; 25101909Objective: To evaluate the effects of fixed orthodontic treatment with steel-ligated conventional brackets and self-ligating brackets on halitosis and periodontal health. Materials and Methods: Sixty patients, at the permanent dentition stage aged 12 to 18 years, who had Angle Class I malocclusion with mild-to-moderate crowding were randomly selected. Inclusion criteria were nonsmokers, without systematic disease, and no use of antibiotics and oral mouth rinses during the 2-month period before the study. The patients were subdivided into three groups randomly: the group treated with conventional brackets (group 1, n = 20) ligated with steel ligature wires, the group treated with self-ligating brackets (group 2, n = 201, and the control group (group 3, n = 20). The periodontal records were obtained 1 week before bonding (T1), immediately before bonding (T2), 1 week after bonding (T3), 4 weeks after bonding (T4), and 8 weeks after bonding (T5). Measurements of the control group were repeated within the same periods. The volatile sulfur components determining halitosis were measured with the Halimeter at T2, T3, T4, and T5. A two-way repeated measures of analysis of variance (ANOVA) was used to compare the groups statistically. Results: No statistically significant group x time interactions were found for plaque index, gingival index, pocket depth, bleeding on probing, and halitosis, which means three independent groups change like each other by time. The risk of tongue coating index (TCI) being 2 was 10.2 times higher at T1 than at T5 (P < .001). Therefore, the probability of higher TCI was decreased by time in all groups. Conclusions: The self-ligating brackets do not have an advantage over conventional brackets with respect to periodontal status and halitosis.Item Effects of platelet-rich fibrin on healing of intra-bony defects treated with anorganic bovine bone mineral(2017) Sezgin, Yasemin; Uraz, Ahu; Taner, I.Levent; Culhaoglu, Rana; 28146219; AAC-5931-2020Anorganic bovine bone mineral (ABBM) is extensively used in the treatment of intra-bony defects. Platelet-rich fibrin (PRF) is a new-generation platelet concentrate with a simplified technique. Although certain studies have reported the use of PRF in the treatment of intra-bony defects, to date, none of them have evaluated its additive effects with ABBM. Therefore, a randomised, split-mouth clinical trial was conducted to compare healing of intra-bony defects treated with an ABBM-PRF combination with healing of those treated with ABBM alone. By using a split-mouth design, 15 paired intra-bony defects were randomly treated with either ABBM alone (control group) or ABBM-PRF combination (test group). Following clinical parameters and radiographical measurements were recorded at baseline and 6 months after treatment: plaque index (PI), gingival index (GI), probing depth (PD), gingival recession (GR), clinical attachment level (CAL), vertical bone loss, depth of defect and defect angle. Preoperative clinical and radiographical measurements were similar for the test and control groups. Statistically significant reductions in GI, PD, CAL, vertical bone loss, depth of intra-bony defect and widening of defect angle were detected after treatment in both groups. With respect to inter-group analysis, gain in CAL was significantly greater in the test group than in the control group, whereas no inter-group differences were observed in any other parameter. The results of this study indicate that both therapies are effective in the treatment of intra-bony defects.
