    (GALENOS YAYINCILIK, 2019) Oznurhan, Fatih; Buldur, Burak; Carti, Ozgul; Tutar, Ugur; Celik, Cem; Hepokur, Ceylan
    Objective: The aim of this in vivo study is to evaluate the effectiveness of a simple herbal caries-prevention protocol for reducing salivary Streptococcus mutans levels in children. Materials and Methods: A total of 90 individuals were recruited randomly divided into three groups (n=30). Mouthwashes including chlorhexidine CHX), licorice and saline were used as tested antimicrobial agents, and saliva samples were collected before rinsing, at the end of 5 min T1) and 60 min T2) following rinsing, and the differences were calculated within 5-60 min T3). Plaques were evaluated following incubation, and counts of the growing colonies were performed in colony forming units CFU)/mL. Decreases in CFU were calculated in ratio for statistical analysis. Data were analyzed with Kruskal-Wallis, Mann-Whitney U, Friedman and Wilcoxon signed rank tests by Bonferroni correction, using a 0.05 of significance level. Results: CHX caused significantly different decreases for T1 and T2 p<0.05), but, there were no significant differences between CHX and licorice for T3 p>0.05). Conclusion: Licorice might be a useful agent for dental procedures and further studies are needed to learn more about the dose of licorice, the ratio of glycyrrhizin and the duration of dental therapy.

    Batman or Joker? A mixed-method approach to understanding children's perceptions of dentists
    (Wiley, 2021) Buldur, Burak
    It is important to understand children's perceptions of dentists in order to improve child-dentist communication. The aim of this mixed-methods study was to develop and validate a conceptual model of individual determinants of children's perceptions of dentists. A total of 1014 children completed an oral health behaviour form, a metaphor form, the Children's Fear Survey Schedule-Dental Subscale, the Dental Trust Scale, and the Early Childhood Oral Health Impact Scale. A conceptual model, which included five endogenous and two exogenous variables, was developed and validated. Qualitative (metaphor analysis) and quantitative (path analysis) analyses were conducted. The metaphors that were used to describe dentists were classified into seven conceptual categories: chaotic and unlovable; scary; artistic; protective and alleviative; restorative; scientific; and educative. Better oral health behaviours, greater trust in dentists, and lower dental anxiety were associated with positive perceptions of dentists. Oral health behaviours, trust in dentists, and dental anxiety had the strongest direct effects on perceptions of dentists, but age had the strongest indirect effect. The developed model should help dentists to understand pathways between children's individual determinants and perceptions of dentists. Coupled with behaviour management, this understanding can be an important part of improving dental visit behaviours and fostering positive post-visit attitudes among children.

    Causes and patterns of permanent tooth loss among 9-15 years old children in the Central Anatolia Region
    (Kerman Univ Medical Sciences, 2020) Candan, Merve; Mavi, Esra; Buldur, Burak
    BACKGROUND AND AIM: The aim of this study was to investigate the causes and patterns of permanent tooth extraction among a subpopulation of 9-15-year-old Turkish children. METHODS: This study employed a retrospective design and consisted of a total of 198 children aged 9 to 15 years attending a dental faculty between January and December 2019. The clinical and radiographic data were obtained from the medical and dental forms from the faculty database. The inclusion criteria included having at least one permanent tooth loss. Age, gender, the Decayed, Missing, and Filled Teeth (DMFT) scores, type and localization of missing permanent tooth/teeth, and reasons for the loss were evalauted. The data were analyzed using descriptive statistics and chi-square test at 0.05 significance level. RESULTS: A total of 198 patients with 309 extracted teeth were evalauted. The mean age of the subjects was 12.95 +/- 1.58 years and mean DMFT score was 6.25 +/- 3.52. Extractions for orthodontic needs (41.7%) and caries-related extractions (32.4%) were the most common causes of tooth loss followed by unsuccessful dental treatments in 13.9% of cases. While the highest DMFT scores were found in dental caries and orthodonic needs groups, the less scores were found in the others group. The most frequently extracted teeth due to caries were the first molar teeth and the first mandibular molars were mostly extracted compared to maxillar first molars. The most frequently extracted teeth due to orthodontic needs and dental caries were seen in girls. CONCLUSION: Orthodontic needs and dental caries were found to be the main causative factors for permanent tooth extractions.

    Clinical effectiveness and parental acceptance of silver diamine fluoride in preschool children: a non-randomized trial
    (Mre Press, 2024) Buldur, Burak; Taskaya, Betul
    Silver diamine fluoride (SDF) presents a promising approach in pediatric dentistry, simplifying procedures by eliminating the need for sharp instruments or anesthesia. This study aimed to evaluate the effectiveness of 38% SDF application in arresting active caries lesions in preschool children and to assess parental acceptance of the treatment. This non-randomized, prospective, single-arm clinical study included 48 children, presenting with a total of 158 active caries lesions. The lesions were treated with 38% SDF, and their characteristics, including changes in dentin color and lesion texture, were evaluated at baseline and at a 6-month follow-up visit. The rate of lesion non-progression post-SDF application was calculated. Additionally, parents completed an oral health behavior form and the Parental Perceptions of Silver Diamine Fluoride Dental Color Changes Questionnaire to assess acceptance. The study observed a high rate of caries arrest in multi-surface teeth following SDF application. There was a statistically significant improvement in parental acceptance of SDF treatment. However, no significant interaction was observed between the treatment and either child- or parent-related variables regarding parental acceptability. The application of 38% SDF effectively arrested caries lesions in preschool children, with an observed increase in parental acceptance pre- and post-treatment.

    Comparison of the Antimicrobial Efficacy of the EndoVac System and Conventional Needle Irrigation in Primary Molar Root Canals
    (JOURNAL PEDODONTICS INC, 2017) Buldur, Burak; Kapdan, Arife
    Purpose: The purpose of this study was to compare the antimicrobial efficacy of the EndoVac system and conventional needle irrigation to eliminate E faecalis in primary molar root canals. Study Design: 60 extracted human primary second molar roots were instrumented up to an apical size.04/35 and randomly divided into two groups; Group 1: conventional needle (n=30) and Group 2: EndoVac (n=30), and four subgroups (two experimental subgroups; (a) 2.5% sodium hypochlorite (NaOCl) + ethylenediaminetetraacetic acid (EDTA) (n=20), (b) ozonated water (OW) + EDTA (n=20), and control groups (c) 5.25% NaOCl (n=10) and (d) saline (n=10). All roots were sterilized and then inoculated with E. faecalis. Before and after final irrigation procedures, root canals were sampled and the grown colony forming units (CFUs) were counted. Data were analyzed by Kruskall-Wallis and Mann-Whitney U tests using a 0.05 significance level. Results: The EndoVac reduced more bacteria than the conventional needle did but it was not statistically significant (p>0.05). NaOCl alone or followed by EDTA totally eliminated bacteria. OW + EDTA showed higher reduction of bacteria but could not totally eliminate bacterias. Conclusions: In the context of bacterial elimination, the EndoVac was not significantly better than the conventional needle. Although, there were fewer CFU/mg when using EndoVac, there was not any statistically significant superiority to conventional needle irrigation. An OW+EDTA regimen showed antibacterial effect in the primary molar root canals but it was significantly less effective than NaOCl+EDTA.

    Conceptual modelling of the factors affecting oral health-related quality of life in children: A path analysis
    (Wiley, 2020) Buldur, Burak; Guvendi, Ozge Nur
    Background It is important to understand the interaction of various predictors with oral health-related quality of life (OHRQoL) to better design effective interventions to improve OHRQoL. Aim The aim of this study was to develop and validate a conceptual model evaluating the factors affecting the OHRQoL in children. Design The study group consisted of 754 parent-child dyads. The data collection tools were a socio-demographic data form, the Early Childhood Oral Health Impact Scale (ECOHIS), Corah Dental Anxiety Scale (C-DAS), Children's Fear Survey Schedule-Dental Subscale (CFSS-DS), and an oral and dental health examination form. A conceptual model was developed to examine the factors affecting OHRQoL in children consisting of four endogenous and four exogenous variables. Path analysis was used to test the compatibility of the conceptual model. Results OHRQoL was associated with parental socio-economic status (beta = -0.12; P < .001), dental anxiety (beta = -0.15; P < .001), and oral health behaviours (beta = -0.13; P < .001). Although parental dental anxiety had the strongest direct effect on OHRQoL, children's oral health behaviours had the strongest indirect effect. Conclusions This study revealed a valid demonstrable path of association between parental socio-economic status, dental anxiety, childhood dental anxiety, oral health behaviours, and OHRQoL.

    (Bmc, 2025) Buldur, Burak; Yildiz, Yasemin
    BackgroundIt is important to delineate how different factors relate to parental acceptance of silver diamine fluoride (SDF).AimTo develop and validate a conceptual model evaluating the factors affecting parental acceptance of SDF.DesignData were collected from 414 preschool children and their parents, and a path model was created to analyse the associations between variables affecting parental acceptability of SDF. The model comprised endogenous and exogenous variables from both parents and children. The psychometric evaluation of a Turkish version of the Parental Perceptions of Silver Diamine Fluoride Dental Colour Changes Questionnaire was also conducted.ResultsParental and child oral health behaviours and the psychosocial impact of dental aesthetics had the greatest indirect effect on parental acceptability of SDF. There were significant associations between parental education level and socioeconomic status, parental socioeconomic status and oral health literacy, parental and children's oral health behaviours, children's oral health behaviours and oral health-related quality of life (OHRQoL), and the psychosocial effects of dental aesthetics and OHRQoL.ConclusionsThis study demonstrated a valid pathway of association between parental and child-related factors and parental acceptance of SDF. Furthermore, the Turkish version of the questionnaire was shown to be both reliable and valid for use.

    (Assoc Apoio Pesquisa & Saude Bucal-Apesb, 2021) Buldur, Burak; Candan, Merve
    Objective: To evaluate the effect of virtual reality (VR) on dental anxiety, pain, and behaviour at different time points among children undergoing dental treatment under local anaesthesia. Material and Methods: This randomised, two-armed, within-subject, cross-over, placebo-controlled trial included 76 children. Eligible participants were treated in two dental visits using the following methods: with protective glasses only, without distraction (attention placebo-controlled - APC); and with the treatment condition (i.e., VR). Primary outcomes were dental anxiety and pain; secondary outcome was dental visit behaviour. Heart rate scores were recorded as an objective measure to evaluate dental anxiety and pain. Subjective measurements for each variable were also performed. Results: Significant reduction in dental pain and anxiety was observed in the VR group, according to the heart rate scores; however, no statistical differences were observed according to the self-reported measures. Decreased dental anxiety and pain were associated with the first visit sequence with VR. Dental pain and anxiety scores were lower during local anaesthesia in the VR group than in the APC group. Conclusion: Virtual reality significantly reduced pain and anxiety during local anaesthesia in children undergoing dental treatment; therefore, it may be recommended during dental treatment in school-age children.

    The effect of intracanal placement of various medicaments on the bond strength of three calcium silicate-based cements to root canal dentin
    (TAYLOR & FRANCIS LTD, 2018) Aydin, Merve Nur; Buldur, Burak
    This study aimed to evaluate the effect of intracanal placement of various medicaments on the bond strength of ProRooT MTA, Biodentine, and Endosequence root repair material (ERRM) putty. Ninety extracted human mandibular premolar teeth were decoronated and instrumented using Protaper Next rotary system and #1 to #6 Peeso reamers. The prepared teeth were randomly divided into six groups according to the intracanal medicaments: Group 1: double antibiotic paste (DAP) consisting of metronidazole and ciprofloxacin; Group 2: Triple antibiotic paste (TAP) with cefaclor; Group 3: TAP with clindamycin; Group 4: amoxicillin and clavulanic acid (Augmentin (R)); Group 5: calcium hydroxide (CH); Group 6: control (no medicament) (n = 15). Parallel transverse sections were obtained in the coronal to the apical direction (4 slices/tooth) and were divided into three subgroups according to the cements: Group A: ProRoot MTA; Group B: Biodentine; Group C: ERRM (n = 20 slices/subgroup). A push-out test was used to measure bond strength. Data were analyzed using twoway analysis of variance and Tukey's post hoc test. The bond strength was significantly lower for DAP and TAPs than for Augmentin (R), CH, or the control (p < 0.05). Biodentine and ERRM had significantly higher bond strength values than ProRooT MTA (p < 0.05) regardless of the intracanal medicaments tested, while no significant difference existed between Biodentine and ERRM (p > 0.05). While the application of DAP or TAPs decreased the bond strength, application of CH or Augmentin (R) did not. ERRM and Biodentine had higher bond strength values than ProRoot MTA.

    Effect of irrigation systems on the bond strength of calcium-silicate-based cement used as pulp barrier in regenerative endodontic treatment
    (Taylor & Francis Ltd, 2023) Hascizmeci, Cihan; Buldur, Burak
    This study aimed to evaluate the effects of irrigation systems on the bond strength of Biodentine, used as a pulp barrier in regenerative endodontic treatment (RET), to the root canal dentin. Following standardized preparation to obtain an immature tooth model, a modified triple antibiotic paste (mTAP) consisting of metronidazole, ciprofloxacin, and clindamycin was applied to the root canals. Teeth were randomly divided into five groups according to the irrigation system (n = 10): Group 1, Conventional Syringe Irrigation (CSI); Group 2, Passive Ultrasonic Irrigation (PUI); Group 3, EndoActivator (EA); Group 4, EndoVac (EV); and Group 5, Nd:YAG laser (LSR). After removing the mTAP from the root canals, parallel sections of 1 mm thickness were obtained, with three sections per tooth. Biodentine was applied to the obtained sections, and a push-out test was performed. The data were recorded in MPa, and images of the fracture types were examined. There was no significant difference between the PUI and EV groups (p > 0.05), and their respective values, (4.43 +/- 0.63) and (4.37 +/- 0.47), were greater than those of the other groups (p < 0.05). Although the push-out bond strength of the LSR group was higher than those of the EA and CSI groups, there was no difference between EA and CSI groups (p > 0.05). The irrigation system type had a significant effect on the push-out bond strength of Biodentine to the root canal dentin in the RET. PUI and EV groups had significantly higher bond strength values than the other groups.

    Endovac sistemi ile uygulanan farklı irrigasyon solüsyonlarının süt dişi kök kanallarındaki antimikrobiyal etkinliğinin ve smear tabakası üzerine etkilerinin incelenmesi
    (Cumhuriyet Üniversitesi, 2013) Buldur, Burak; Kapdan, Arife
    Bu çalışmanın amacı, EndoVac sistemi ve geleneksel şırınga yöntemiyle uygulanan farklı irrigasyon solüsyonlarının, süt dişi kök kanallarındaki smear tabakasına olan etkisi ve antimikrobiyal etkinliklerinin in vitro olarak incelenmesidir. Çalışmada 120 adet çekilmiş alt ve üst çene süt insan azı dişlerinin distal ve palatinal kökleri kullanıldı. Dişlerin boyları 11±1 mm olacak şekilde elmas separe ile kronları uzaklaştırıldı ve çalışma boyutu tespit edildikten sonra silikon kalıplara gömüldü. Profile .04 series kanal eğeleriyle crown-down yöntemi kullanılarak ve apikalde en son 35.04 kanal eğesi kullanılarak dişlere standart preperasyon işlemleri gerçekleştirildi. Daha sonra dişler rastgele olacak şekilde 2 ana bölüme ayrıldı. Çalışmanın birinci bölümünde smear tabakası incelemesi yapıldı. 60 diş iki ana gruba (Geleneksel n= 30 ve EndoVac n= 30) ve her bir ana gruba ait 2 deney grubunda 10' ar diş ( %2,5 NaOCI+%17 EDTA , 4 ppm Ozonlu Su+%17 EDTA) ve her bir kontrol grubunda 5' er diş olmak üzere 1 pozitif kontrol grubu ( Serum Fizyolojik) ve 1 negatif kontrol grubu ( %17 EDTA ) olacak şekilde rastgele gruplara ayrıldı. Gruplara solüsyon akış hızı 5ml/dk olacak şekilde toplam 6 dakika final irrigasyon işlemleri uygulandıktan sonra diş kökleri uzun aksları boyunca ikiye ayrıldı ve kökün sağlam yarısı SEM' de incelendi. Koronal, orta ve apikal üçlü bölgelerinden X1000 büyütmede görüntüler alınarak smear tabakası varlığı yönünden skorlandırma yapıldı. Çalışmanın ikinci bölümünde mikrobiyolojik inceleme yapıldı. 60 diş steril edildikten sonra içerisinde E. faecalis bulunan 15 µl süspansiyon ile steril mikro pipetler kullanılarak kontamine edildi ve 24 saat etüvde bekletildi. Daha sonra dişler iki ana gruba (Geleneksel n= 30 ve EndoVac n= 30) ve her bir ana gruba ait 2 deney grubunda 10' ar diş ( %2,5 NaOCI+%17 EDTA , 4 ppm Ozonlu Su+%17 EDTA) ve her bir kontrol grubunda 5' er diş olmak üzere 1 pozitif kontrol grubu ( SF ) ve 1 negatif kontrol grubu ( %2,5 NaOCI ) olacak şekilde rastgele gruplara ayrıldı. Gruplardaki final irrigasyon işlemi öncesinde ve sonrasında steril kağıt konlar ile kök kanalından alınan örnekler içerisinde 0,5 ml BHI bulunan ependorf tüplere aktarıldı ve oluşan bu süspansiyonlardan 10 µl alınarak kanlı agar besiyerinin ortadan bölünmüş iki ayrı tarafına ekim yapıldı. Kalan bakterilerin koloni sayımı CFU sınıflamasına göre yapıldı. Çalışmanın verilerinin istatistiksel değerlendirilmesinde Kruskall Wallis ve Mann-Whitney U testleri kullanıldı ve yanılma düzeyi 0,05 olarak alındı. Çalışmanın smear tabakası incelenen bölümünde irrigasyon yöntemi olarak EndoVac sistemi, tüm alt gruplarda apikal üçlü bölgede smear tabakasını uzaklaştırmada geleneksel yöntemden istatistiksel olarak daha başarılı bulundu (p?0,05). Kök kanallarında smear tabakası uzaklaştırmada irrigasyon solüsyonu olarak pozitif kontrol grubuyla diğer gruplar arasında istatistiksel fark anlamlı bulunurken (p?0,05), diğer üç grup arasında anlamlı fark bulunmadı (p?0,05). Serum fizyolojik hariç diğer tüm gruplarda smear tabakası kaldırılmıştır ancak EndoVac ve geleneksel ana gruplarındaki alt gruplarda koronal ve orta üçlü bölgede smear tabakası kaldırmada anlamlı fark bulunamazken (p?0,05), apikal bölgede anlamlı fark bulundu (p?0,05). Çalışmanın mikrobiyolojik inceleme bölümünde ise irrigasyon yöntemi olarak EndoVac sisteminin, ozonlu su ve serum fizyolojik gruplarındaki antimikrobiyal etkinliğinin geleneksel yöntemden daha yüksek olduğu ancak istatistiksel olarak bu farkın önemli bulunmadığı tespit edildi (p?0,05). İrrigasyon solüsyonları olarak alt NaOCI+EDTA grubu ve sadece NaOCI uygulanan negatif kontrol grubunda tam bakteri eliminasyonu gerçekleştirildi. Ozonlu su+ EDTA uygulanan alt gruplarda tam olmamakla beraber yüksek oranda bakteri elimine edildiği saptandı ve kalan bakteri sayısı serum fizyolojik grubuna göre istatistiksel olarak anlamlı olacak şekilde daha az bulundu (p?0,05). İrrigasyon yöntemi olarak EndoVac sisteminin hem smear tabakasını uzaklaştırma hem de antimikrobiyal etkinlik açısından geleneksel yöntemden daha başarılı bulunması nedeniyle süt dişi kök kanal tedavilerinde EndoVac sisteminin etkili bir irrigasyon yöntemi olduğu sonucuna varıldı. Ozonlu suyun ise bakteri sayısını önemli ölçüde azalttığı ancak tamamen elimine edemediği sonucuna varıldı.

    Evaluation of the Effect of Different Irrigation Systems on the Removal of Intracanal Medicaments
    (Cumhuriyet University Faculty of Dentistry, 2023) Hascizmeci, Cihan; Buldur, Burak
    Objectives: This study aimed to evaluate the effects of different irrigation systems on the removal of intracanal medicament used in regenerative endodontic treatment. Materials and Methods: Following standardized preparation to obtain an immature tooth model, modified triple antibiotic paste (mTAP) consisting of metronidazole, ciprofloxacin and clindamycin was applied to the root canals of single-rooted human maxillar teeth and waited for three weeks. A total of 50 teeth with standardized preparation and intracanal medicament were randomly divided into five groups according to the irrigation method to be applied (n=10); Group 1: Conventional Syringe Irrigation (CSI), Group 2: Passive Ultrasonic Irrigation (PUI), Group 3: EndoActivator (EA), Group 4: EndoVac (EV) Group 5: Nd:YAG laser (LSR). Following the removal of the mTAP with different irrigation systems, the teeth were divided along their bukko-lingual axis. The impact roots were examined under the stereomicroscope with the 4-grade scoring scale for the presence of residual intracanal medicaments. Scores for coronal, middle and apical regions of each root were recorded. Results: In terms of total scores, PUI group showed higher intracanal medicament removal efficacy compared to the other groups (p<0.05). In the intra-group comparison of the root canal third, less intracanal medicament was found in the apical third (p <0.05). The highest intracanal medicament removal efficacy was found in PUI and LSR groups in the coronal third, PUI group in the middle third, and PUI and EV groups in the apical third (p<0.05). Conclusions: Intracanal medicament removal scores were significantly associated with irrigation system. PUI showed statistically significantly higher intracanal medicament removal efficiency than other irrigation methods. While there was no difference between the coronal and middle thirds, statistically significantly less intracanal medicament removal was found in the apical third compared to the other regions. © This work is licensed under Creative Commons Attribution 4.0 International License

    Factors Associated with Knowledge and Attitude of Management of Traumatic Dental Injuries: A Cross-Sectional Study among Turkish Dentists
    (ASSOC APOIO PESQUISA & SAUDE BUCAL-APESB, 2018) Buldur, Burak; Kapdan, Alper
    Objective: To evaluate the factors associated with knowledge and attitude of dentists regarding management of traumatic dental injuries (TDI). Material and Methods: In this cross-sectional and correlational study, the sample consisted of 136 Turkish dentists. A specialized questionnaire was developed and validated to collect data. The first part of the questionnaire included questions about sociodemographic characteristics, education level, working experince, working place, last dental trauma course, self-efficacy about management of TDI, and treatment frequency. The second part included a total of 17 questions with multiple choice and single correct answers regarding the management of intrusion and extrusion, avulsion, complicated crown fracture and crown-root fracture injuries in children. Descriptive statistics, multivariate analysis of variance, and partial eta squared coefficient (. 2) were used for statistical analysis. Results: There was a moderate level of knowledge among participants. The level of knowledge was statistically correlated (p<0.05) in terms of working experience, working place, last dental trauma course and education level of participants, but not according to gender, self-efficacy, and treatment frequency (p>0.05). General dentists had lower self-efficacy than specialist dentists (p<0.05). Conclusion: While Turkish dentists working in a province seem to have a moderate level of knowledge regarding treatment of different types of TDI, it is necessary to carry out necessary studies to improve the knowledge and raise self-efficacy.

    Objectives: The objective of this study was to assess the present knowledge level of emergency measures for tooth avulsion in schoolchildren with sports education in Sivas. Materials and Methods: A total of 112 schoolchildren aged 15-18 years old, were interviewed bu professionals using a standardized method to score knowledge about tooth avulsion and replantation. The following fields of knowledge were assessed tooth avulsion and replantation principles, avulsed permanent/primary teeth, cleaning of avulsed tooth before replantation, extra alveolar time and storage media. Chi-square test was used for statistical analysis. Results: Regardless of age group, there were generally a low knowledge level regarding tooth avulsion, replantation, extra alveolar time and storage media. When comparing special knowledge level of the avulsion and replantation of the permanent/primary teeth according to the age groups, the differences between age groups were found statistically important. 16 and 17 age groups had middle knowledge level. The lowest knowledge level was in 15 age group. Concerning with storage media, 60,4% of students preferred water and 11,4% of students preferred milk for storage media. Conclusions: We conclude that first-aid knowledge in schoolchildren with sports education is low on avulsion and replantation of teeth and the knowledge level of first-aid measures on avulsion and replantation of teeth could be increased through intervention programs.

    Metaphorical perceptions of dental students toward dental education: a cross-sectional study from Türkiye
    (Bmc, 2025) Aksu, Seckin; Erturk-Avunduk, Ayse Tugba; Delikan, Ebru; Buldur, Burak
    Background Understanding the complex, multifaceted, and often subconscious emotional and cognitive perspectives of undergraduate dental students regarding their education is crucial. Personality types and stress levels are believed to play a significant role in shaping these perceptions. Employing metaphors-using a familiar and concrete concept to explain an unfamiliar or abstract one-is an effective cognitive transfer technique for exploring students' views on dental education. This cross-sectional study aims to investigate dental students' perceptions of their education through metaphor analysis. Additionally, it aims to examine the relationship between students' personality types and stress levels, offering deeper insights into the factors influencing their educational experiences. Methods This cross-sectional study included 1038 undergraduate dental students enrolled in faculties of dentistry at three universities in Turkiye during the 2023-2024 academic year. Data were collected via an electronic survey consisting of four sections. The first section gathered demographic information (gender, age, academic level, and occupational preference). In the second section, participants completed the sentence: Dental education is similar to & mldr; because & mldr; to illustrate their mental representations of dental education. The third section included the Perceived Stress Scale (PSS) to assess stress levels, while the fourth section comprised a personality inventory to determine personality types. All survey data were transferred to Excel for analysis. Metaphors were systematically evaluated, and the most representative ones were identified. Data analysis incorporated both qualitative (metaphor analysis and chi-square tests) and quantitative (linear regression) methods. Results Metaphors were categorized into seven conceptual groups: 'master-apprentice training', 'challenging process-race', 'art-skill-creativity', 'patience-labor', 'union of differences', 'discipline-order-power', and 'unknowability-incomprehensibility-indispensability'. A significant gender difference was observed (p = 0.013): female students predominantly used metaphors in the 'patience-labor' category, while male students favored the 'art-skill-creativity' category. Academic year differences were also significant (p < 0.001), with advanced students more frequently using 'discipline-order-power' metaphors. Stress levels did not significantly differ among groups (p = 0.127), with 72.1% of participants reporting moderate stress, most commonly linked to the 'challenging process-race' category. The majority of participants (64.5%) exhibited a Type B personality. A statistically significant regression model was found between PSS scores and both age (p < 0.001) and personality type scores (p = 0.011). Conclusion This study highlights the influence of personality types and stress levels on dental students' perceptions of their education. Metaphor analysis proved to be an effective tool for identifying these perceptions. The most frequently reported category was 'challenging process-race'. A significant association was found between students' metaphorical categories and their gender and academic level. However, no significant relationships were observed between metaphor categories and occupational preference, stress levels, and personality types.

    More than just a child: dental students' perceptions of children using a mixed-method approach
    (Mre Press, 2024) Buldur, Burak; Erdem, Sumeyye
    It is important to understand perceptions of dental students towards children to better design relationship. This study aimed to determine and conceptualize dental students'perceptions of children. The study group consisted of 514 dental students who were asked to complete the statement A child is like..., because.... The metaphors were sorted into conceptual categories and examined for any significant differences between gender, education level and occupational preference. Quantitative (metaphor analysis) and qualitative (chi-square) analyses were used. Participants produced 421 metaphors under 33 general metaphors. The metaphors were collected under five conceptual categories: children as (1) requiring care, attention and sensitivity; (2) raw material; (3) developing and changing; (4) unpredictable and surprisingly; and (5) hazard. The metaphors were mostly under the developing and changing category. There were no significant differences between the groups in terms of gender, education level and occupational preference. Female and clinical dental students mostly produced metaphors in the requiring care, attention and sensitivity and developing and changing categories, respectively. Metaphor analysis is a useful tool in determining dental students' perceptions. Understanding dental students' perceptions of children can be an important part of fostering positive perceptions in their professional life.
