Resilience and psychological factors among dentistry students who received face-to-face lectures during the COVID-19 pandemic.

BACKGROUND: This research evaluated whether the relationships between factors of resilience, self-esteem, depression, and anxiety in dental students with changes in teaching and learning methods. We also studied the psychological impact of face-to-face lectures during the COVID-19 pandemic. METHODS: This cross-sectional descriptive study used Google Forms to collect data with the Rosenberg Self-Esteem Scale (RSE), Connor-Davidson Risk Resilience Scale (CD-RISC), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI and BDI-II). An open-ended question was also asked about important learning difficulties. RESULTS: The analysis revealed very high levels of resilience (30.23 ± 5.84), self-esteem in the normal range (29.08 ± 4.03), minimal depression levels (12.32 ± 8.05), and low anxiety levels (17.20 ± 12.41). There were no significant differences between sociodemographic variables ranges in regard to all psychological questionnaires. No high levels of depression and anxiety were found. CONCLUSIONS: The levels were low compared to other studies in which online teaching was used, which is explained by the fact that the students retained adequate resilience and self-esteem thanks to being able to contact teachers and, above all, their own peers.

Molar root canal treatment performed by undergraduate dental students; an observational study of procedural errors and student perception.

BACKGROUND: Molar root canal treatment (RCT) is challenging and requires training and specific skills. Rotary instrumentation (RI) reduces the time needed for instrumentation but may increase the risk of certain procedural errors. The aims of this study were to evaluate the quality of molar RCTs provided by undergraduate students, to compare the prevalence of procedural errors following manual and RI, and to assess the students' self-perceived confidence to perform molar RCT without supervision and their preference for either manual or RI. METHODS: Molar RCTs performed by the final year students were evaluated radiographically according to predefined criteria (Appendix 1). The procedural errors, treatment details, and the students' self-perceived confidence to perform molar RCT and their preference for either manual or RI were recorded. Descriptive statistics were performed, and the Chi-squared test was used to detect any statistically significant differences. RESULTS: 60.4% of RCTs were insufficient. RI resulted in more sufficient treatments compared with MI (49% vs. 30.3% respectively. X2: 7.39, p = 0.007), required fewer visits to complete (2.9 vs. 4.6 respectively. X2: 67.23, p < 0.001) and was the preferred technique by 93.1% of students. The most common procedural errors were underextension of the root canal obturation (48.4%), insufficient obturation (45.5%), and improper coronal seal (35.2%) without a significant difference between the two techniques. 26.4% of the participating students reported that they did not feel confident to perform molar RCT without supervision. CONCLUSION: The quality of molar RCT provided by UG students was generally insufficient. RI partially improved the technical quality of RCT compared with MI. UG students need further endodontic training and experience before they can safely and confidently practise molar RCT.

Assessment of dental students' knowledge and performance of master gutta-percha cone selection and fitting during root canal treatment: a pilot study.

BACKGROUND: Misconceptions should be detected early in dental students' training to improve their clinical performance. Accordingly, this study aimed to assess undergraduate dental students' knowledge and performance of master gutta-percha (GP) cone selection and fitting during clinical endodontic courses at the College of Dentistry, King Saud University. METHODS: Ninety-nine undergraduate dental students completed an online survey about their knowledge of master GP cone selection. Forty-five of these students were observed by faculty members in clinical endodontic courses while they fitted master GP cones during root canal treatments. The observers recorded the details of each student's cone-fitting techniques. The data were analysed using t-tests, one-way analysis of variance, and chi-square tests (p < 0.05). Inter- and intra-observer reliability were tested using Fliess' Kappa. RESULTS SURVEY: All participants had good knowledge of over-extended cone management, while 80.8% knew how to properly manage a short cone. The proper flaring assessment method was selected by 86.9% of the female and 34.2% of the male students, and this difference was statistically significant (p = 0.0001). OBSERVATION: The students labelled the working length on the master GP cone with an indentation in 64.4% of the cases and by bending the cone 35.6% of the time. Of all students, 84.4% encountered an apical stop, and this rate correlated significantly with the length of the cone on the master apical cone radiograph (p = 0.001). Improper shaping of the canal was the most common cause of ill-fitting cones (83.3%), while 16.7% of the students chose the wrong cone size. The final obturation length was adequate in 80% of the cases; 57.8% of the students were helped by instructors. CONCLUSIONS: Most students had the basic knowledge required to solve problems related to the selection of master GP cones. However, in the clinical setting, more than half of the students required the assistance of an instructor to adjust their cone's fit. The presence of an apical stop had the most significant effect on the length of the fitted master GP cone on radiography. The most common cause of ill-fitting master cones was improper shaping of the canal.

Longevity of composite restorations in posterior teeth placed by dental students: a 12-year retrospective study.

OBJECTIVES: To evaluate the longevity of resin composite restorations placed in posterior teeth by dental students, using data from electronic records from 2008 to 2019. MATERIALS AND METHODS: Demographic (gender and age) and clinical variables (dental group, position in dental arch, and the number of restored surfaces) were evaluated. The 5-year follow-up was assessed according to the day the restoration was placed. Kaplan-Meier curves were generated to calculate the annual failure rate. Data were analyzed by Chi-Square, Kruskal-Wallis, and Mann-Whitney tests (α = 0.05). RESULTS: In total, 3.883 records relative to return periodicity were analyzed. The final sample consisted of 900 restorations from 479 patients. The majority were females, aged between 31 and 60. In total, 256 failures were reported (success rate = 78%), showing an annual failure rate of 2.05%. The main reasons for failures were restoration replacement (55.5%), endodontics (21.9%), prosthetics (14.5%) and extraction (8.2%). There was a higher risk of failure in restorations involving three or more surfaces (p = 0.000) and in patients over 60 years (p < 0.001). In females (p = 0.030), molars (p = 0.044), and maxillary teeth (p = 0.038) failed in a shorter time. CONCLUSIONS: Resin composite restorations placed in permanent posterior teeth by dental students had high survival rates. The main reason for failure was the replacement of restorations. The age group and the number of restored surfaces significantly affected the success of the restorations. CLINICAL RELEVANCE: The electronic health records over 12 years showed that 78% of the resin restorations in posterior teeth placed by dental students were successful for a minimum of five years.

Resilience and academic performance: Exploring the link in dental students.

This study aims to assess the correl ation between t he resilience level of dental students (preclinical and clinical years) and its effects on their academic performance. It is a correlational research study that was carried out on second, third, and final-yea r denta l students at Lahore Medical & Dental College, Lahore. Academic resilience was judged by using the academic resilience scale (ARS-30). The correlation between resilience and academic performance was e s tablished by appl ying the bivar iate Pea rso n correlation. The mean age of the stude nt s was 2 1.49±1.39 years. Among 196 dental students from different years, 132 (67.35%) were females and 64(32.65%) were males. A strong p ositive co rrelati on was obser ved bet ween the academic performance and resilience of denta l students, i.e. r=0.774. From the results, it can be concluded that there is a positive correlation between academic resilience and academic performance among dental students.

Effect of group and individual education on shade matching competency of dental students.

PURPOSE: To evaluate the influence of group and individual education on shade matching quality using a visual color competency test to match shade tab pairs from two Vita classical A1-D4 shade guides. METHODS: 60 dental students, 21-25 years old (39 females, 21 males) participated in the study. All participants passed a color deficiency test before the experiment. The examination was voluntary and approved by the corresponding Ethics Committee. Students were randomly divided into three groups (n=20): one control group, NE (no education) and two experimental groups - GE (group education) and IE (individual education). The study was performed in three phases. In the "before" (B - Phase 1) and "after" (A - Phase 3) phase, all groups had to match 16 pairs of tabs from two Vita classical A1-D4 shade guides, with the shade designations hidden by custom letter markings. All tabs were mixed on a gray surface illuminated by color-correcting light. In Phase 2 (between B and A), GE had only group education, while IE received additional individual education and training. The control group did not participate in Phase 2. Means and standard deviations were calculated, and differences were compared using the one-way ANOVA, ANCOVA test, and Student t-test for dependent samples (α= 0.05). RESULTS: The NE group matched 10.3 (3.2) and 10.4 (2.9) tab pairs in the before and after phases, respectively. Corresponding results for GE were 11.1 (2.2) and 14.4 (1.9) and 9.5 (3.6) and 15.0 (1.5) for IE, respectively. In Phase 1 (B), no statistically significant difference was recorded among the groups (P= 0.260). The experimental groups achieved a statistically significant improvement compared with the control group in Phase 3 (A) (P< 0.001). Both experimental groups achieved statistically significant improvement within the group after education, GE (P< 0.001) and IE (P< 0.001). Within the limitations of this study, it was concluded that both experimental groups had statistically significant progress in shade matching. The group that received individual education (IE) made statistically significant progress compared with the group that received group education (GE). No statistically significant difference was found in the results of the control group between Phase 1 and Phase 3 of the study. CLINICAL SIGNIFICANCE: Improving the shade matching ability facilitates the work of dentists and dental technicians and enhances the esthetics of dental restorations.

Exploring changes in the perception of e-professionalism among medical and dental students: a quantitative cross-sectional study.

AIM: To compare e-professionalism perceptions between medical and dental students, focusing on their awareness and understanding of guidelines for developing e-professionalism. METHODS: A cross-sectional quantitative study was conducted at the University of Zagreb School of Medicine (UZSM) and School of Dental Medicine (UZSDM) in 2022/2023. Data were gathered through a questionnaire designed specifically for the survey. RESULTS: Of the 646 questionnaires collected, 626 were analyzed, with a response rate of 33.95% for UZSM and 37.83% for UZSDM. Most respondents (71.4%) were female, with a median age of 21. Medical students significantly more frequently considered it unprofessional to publish posts containing photos of patients/clients (96.5% vs 75.1%), endorsements of health products without conflict-of-interest disclosures (60.6% vs 33.0%), and posts describing patient interactions without revealing identifying information (51.7% vs 27.4%). In contrast, dental medicine students more frequently considered it unprofessional to publish posts with swearing or foul language (81.2% vs 67.4%), critical comments about lecturers (68.0% vs 46.9%), and criticisms of course material or the institution (52.3% vs 36.4%). Only 23.2% of students were aware of e-professionalism guidelines, with 37.9% of those familiar with their content. CONCLUSION: While medical and dental students recognize the importance of e-professionalism, their perceptions have substantial differences. The need for promoting existing guidelines and integrating e-professionalism into curricula is evident. Continuous monitoring and research in this domain are essential to ensure future health care professionals maintain high standards of online professionalism.

Illustration of self-perceived knowledge, skills, and interests in undergraduate dental students using a visual metaphor- results of a monocentric cross-sectional study.

BACKGROUND: Self-assessment and self-reflection of competencies are crucial skills for undergraduate students. This monocentric cross-sectional study aims to assess the self-perceived knowledge, skills and interests in conservative dentistry and periodontology of third-, fourth-, and fifth-year dental students by the Pictorial Representation of Illness and Self-measure (PRISM). METHODS: Seventy-five undergraduate dental students (n = 25 of each year) who studied between 2021 and 2022 at the Department of Cariology, Endodontology and Periodontology at the University of Leipzig, Germany, were included. All of them underwent a PRISM-based interview regarding their perceived knowledge, practical skills, and interests in conservative dentistry as well as its sub-disciplines. The distances in the PRISM task (in millimeters) were measured and compared between the groups. Spearman's Rho was used to reveal correlations between knowledge, skills, and interests in the cohort. RESULTS: Perceived theoretical knowledge and practical skills differed significantly between groups for the sub-disciplines periodontology, cariology, restorative dentistry and preventive dentistry (p < 0.05). However, students' interests did not significantly vary between groups (p > 0.05). In the field of conservative dentistry and its sub-disciplines, significant moderate to high positive correlations were found between knowledge and skills (p < 0.01), and weak to moderate positive correlations were found between interests and knowledge (p < 0.05). Regarding the relationship between perceived interests and skills, only restorative dentistry, endodontology and periodontology were significant and only moderate to weak correlations were found (p < 0.05). CONCLUSION: PRISM revealed differences in perceived knowledge and skills between third-, fourth-, and fifth-year dental students. Correlations were found between perceived knowledge and skills, as well as between interests and knowledge. PRISM may be a promising tool to support students and teachers in dental education.

Performance of dental students, orthodontic residents, and orthodontists for classification of midpalatal suture maturation stages on cone-beam computed tomography scans - a preliminary study.

BACKGROUND: Assessment of midpalatal suture maturation on cone-beam computed tomography (CBCT) scans is performed by visual inspection and is therefore subjective. The extent to which the assessment of midpalatal suture maturation is affected by rater experience has not been adequately explored in the existing literature, thus limiting the availability of evidence-based findings. This study compared the outcomes of classification by dental students, orthodontic residents, and orthodontists. METHODS: Three different groups of students, orthodontic residents, and orthodontists evaluated 10 randomly chosen CBCT scans regarding midpalatal suture maturation from a pool of 179 patients (98 female and 81 male patients) aged 8 - 40 years which were previously classified by evaluating CBCT scans. The pool was set as benchmark utilizing midpalatal suture maturation classification by one examiner (OsiriX Lite version 11.0; Pixmeo SARL, Bernex, Switzerland). For assessment of intra-rater reliability of the examiners of each group the randomly chosen subjects were reclassified for midpalatal suture maturation after a wash-out period of two weeks by using the same software. Statistical analysis was performed to evaluate intra- and interrater reliability of the three groups with differing experience level. RESULTS: Groupwise intra-rater reliability assessment between the classification and reclassification was weak for examiners with a low level of experience (k = 0.59). Orthodontists had highest degree of agreement with regard to benchmark classification with an inter-rater reliability to be considered as moderate (k = 0.68). CONCLUSIONS: Assessment of midpalatal suture maturation on CBCT scans appears to be a subjective process and is considerably related to the experience level of the examiner. A high level of clinical experience seems to be favorable but does not necessarily ensure accurate results.

Influence of education level and gender of dental students on perception of dental aesthetics.

BACKGROUND: Fulfilling aesthetic norms is an imperative of modern society. Accordingly, aesthetics has found its important role in dental medicine. The aim was to study whether there is a difference in the perception of tooth shade change and anatomical variations of anterior maxillary teeth among dental students depending on the level of education, gender, and experience in assisting in a dental office. METHODS: The research was conducted among dental students via the Google Forms platform. Students evaluated the aesthetic acceptability of a smile on the unaltered, reference photograph (RP) and on the other 28 photographs in which the tooth shade (lighter and darker teeth), length (shortened central incisors, elongated, and beveled lateral incisors, elongated canines) and position (atypical and typical rotations and diastemas) of the upper maxillary teeth were altered by digital manipulation. The 1-10 assessment scale was used. Statistical analysis comprised one-way Kolmogorov-Smirnov test, X2 tests, t-test, and 3-way MANOVA. RESULTS: In the research 208 students participated, 113 were preclinical students, 104 assisted in dental office and 175 were females. There were no significant effects of gender regarding length and position modifications (p > .05), while women were stricter in evaluation of lighter shade (p < .05). Clinical students were stricter in evaluating all manipulated photographs (MP) except those towards darker shade modifications, while assisting in a dental office or having a dentist in close family showed no significant effects (p > .05). CONCLUSIONS: With a higher level of targeted academic education, dental students sharpen their ability to notice deviations from the aesthetic norms of a smile.

Assessing the performance of Bing Chat artificial intelligence: Dental exams, clinical guidelines, and patients' frequent questions.

OBJECTIVES: Bing Chat is a large language model artificial intelligence (AI) with online search and text generating capabilities. This study assessed its performance within the scope of dentistry in: (a) tackling exam questions for dental students, (ii) providing guidelines for dental practitioners, and (iii) answering patients' frequently asked questions. We discuss the potential of clinical tutoring, common patient communication and impact on academia. METHODS: With the aim of assessing AI's performance in dental exams, Bing Chat was presented with 532 multiple-choice questions and awarded scores based on its answers. In evaluating guidelines for clinicians, a further set of 15 questions, each with 2 follow-up questions on clinical protocols, was presented to the AI. The answers were assessed by 4 reviewers using electronic visual analog scale. In evaluating answers to patients' frequently asked questions, another list of 15 common questions was included in the session, with respective outputs assessed. RESULTS: Bing Chat correctly answered 383 out of 532 multiple-choice questions in dental exam part, achieving a score of 71.99 %. As for outlining clinical protocols for practitioners, the overall assessment score was 81.05 %. In answering patients' frequently asked questions, Bing Chat achieved an overall mean score of 83.8 %. The assessments demonstrated low inter-rater reliability. CONCLUSIONS: The overall performance of Bing Chat was above the regularly adopted passing scores, particularly in answering patient's frequently asked questions. The generated content may have biased sources. These results suggest the importance of raising clinicians' awareness of AI's benefits and risks, as well as timely adaptations of dental education curricula, and safeguarding its use in dentistry and healthcare in general. CLINICAL SIGNIFICANCE: Bing Chat AI performed above the passing threshold in three categories, and thus demonstrated potential for educational assistance, clinical tutoring, and answering patients' questions. We recommend popularizing its benefits and risks among students and clinicians, while maintaining awareness of possible false information.

Dental Students' Satisfaction With Web-Based Learning During the Initial Phase of the COVID-19 Pandemic: Mixed Methods Study.

BACKGROUND: The COVID-19 pandemic has precipitated an accelerated shift in education, moving from traditional learning to web-based learning. This transition introduced a notable transactional distance (TD) between the instructors and learners. Although disease control and staff and students' safety are the top priorities during a pandemic, the successful delivery of education is equally crucial. However, the ramifications of this swift transition are particularly critical in the context of dental education. Dental education is inherently practice oriented, necessitating hands-on training and manual skills development, which poses unique challenges to distance learning approaches. OBJECTIVE: This study aims to examine dental students' web-based learning satisfaction and experience of TD, investigate the predictors of web-based learning satisfaction, and explore the perceptions of students about the advantages and disadvantages of web-based learning. METHODS: This study explored the factors associated with web-based learning satisfaction using TD theory during the transition to web-based education. Psychological factors that could influence satisfaction were adapted from the health belief model. We conducted a cross-sectional web-based survey of 345 dental students from 2 institutions in South Korea who were enrolled in the spring semester of 2020. Data were collected between July 8 and September 14, 2020. Qualitative analysis was used to examine responses to open-ended questions concerning perceptions of web-based learning. RESULTS: A multivariate hierarchical linear regression model was used to analyze the effects of student characteristics, TD, and psychological factors (ie, perceived risk of infection and efficacy belief of web-based learning) on web-based learning satisfaction. The average score for web-based learning satisfaction was 3.62 (SD 0.84), just above the midpoint of the possible range (1-5). Self-regulated learning (ß=0.08; P=.046), learner-instructor interaction (ß=0.08; P=.03), and learner-content interaction (ß=0.64; P<.001) were associated with higher levels of satisfaction. Moreover, a significant association was revealed between high efficacy beliefs in web-based learning (ß=0.20; P<.001) and satisfaction. Although the learning structure (synchronous vs asynchronous) did not exhibit a significant association with satisfaction, the qualitative analysis results revealed that each structure possesses distinct strengths and weaknesses. The students in synchronous learning (79/345, 22.9%) recognized heightened autonomy in the "learning environment" (19/79, 24%); however, technical issues (28/79, 35%) and reduced concentration (15/79, 19%) were identified as downsides. Conversely, the students in asynchronous settings (266/345, 77.1%) emphasized unlimited access to learning content (74/266, 27.8%) and the flexibility of "learning in preferred time" (69/266, 25.9%). Nevertheless, challenges, such as self-management difficulties (66/266, 24.8%) and limited interactions (55/266, 20.7%), were evident. CONCLUSIONS: The findings suggest that efforts to minimize TD, facilitating self-regulated learning and interaction among students and instructors, are critical for achieving web-based learning satisfaction. Moreover, establishing a common understanding among students regarding the necessity and efficacy of web-based learning during epidemics could enhance their satisfaction.

Perceptions and Knowledge of Undergraduate Dental Students about Artificial Intelligence in Dental Schools: A Cross-sectional Study.

OBJECTIVE: This study aims to assess the perceptions and knowledge of undergraduate dental students about artificial intelligence (AI) in dental schools through a cross-sectional study. MATERIALS AND METHODS: This was a multicenter, cross-sectional study. Participant recruitment was achieved by sending an online questionnaire to the undergraduate students at the assigned universities. The questionnaire consisted of two parts. The first seven questions record general information about participants and their perceptions of AI. The remaining questions are about the knowledge of participants about the applications of AI. The data were analyzed using SPSS version 26. RESULTS: About 165 undergraduate students from 20 universities related to the dental sciences responded to the questionnaire. And 80.6% of participants found the use of AI in dentistry exciting. I have a basic knowledge of the working principles of AI. About 80.6% of participants believe that applications of AI should be part of undergraduate dental training. And 66.6% of students are aware of the opportunities and threats that AI can create. The results show that 75% of the students indicated that they got their information about AI through social media. Regarding the association of years of studies with AI applications used in periodontics, the knowledge about AI applications in "aggressive periodontics," "compromised teeth," and "success in rate of dental implant" was significantly higher in senior students than junior students (p < 0.05). Concerning applications of AI used in restorative dentistry and prosthodontics, only "computer color matching," "tooth surface losses," and "I do not know" showed statistical significance (p < 0.05) with the year of study of participants. Senior students show significantly better knowledge in "success in retreatment" and "working length determinant." CONCLUSION: Although undergraduates are enthusiastic about AI and aware of its threats and benefits, their knowledge is limited. In addition, undergraduate programs must exert more effort to prepare students for the era of AI. How to cite this article: Aldowah O, Almakrami A, Alghuwaynim Y, et al.

Utilization of 3D evaluation for assessing selective caries removal practice in pre-clinical dental students: a pilot study.

BACKGROUND: Practicing and assessment of selective caries removal techniques in dental students remain challenges in many dental schools. The aim of this study was to utilize a 3D assessment technique, within a designated acceptable range of deviation, to evaluate the tendency of dental students in performing selective caries removal (SCR). The correlation between 3D assessment results and the conventional rubric rated by an instructor was also determined. METHODS: Fifth-year dental students (n = 61) performed the SCR task on 3D-printed teeth containing simulated deep caries lesions in occlusal and proximal surfaces. One instructor assessed the results using a conventional analytic rubric. The excavated teeth were additionally evaluated using 3D analysis software with the designated acceptable range of deviations (± 0.5 mm) from the standard cavities. The average root mean square (RMS) value, representing the deviation between student-prepared cavities and the predefined standard cavities, was recorded. A tendency towards over-excavation was defined for RMS values > 0.5 mm, and towards under-excavation for RMS values < 0.5 mm. RESULTS: The mean (min-max) of RMS was 0.27 (0.18-0.40) for occlusal and 0.29 (0.20-0.57)for proximal cavities. A tendency of dental students toward over-excavation was observed in both occlusal (74%) and proximal cavities (87%). There was a moderate negative correlation between the RMS values and the traditional rubric scores for both occlusal (R2 = 0.148, P = 0.002) and proximal cavities (R2 = 0.107, P = 0.010). CONCLUSIONS: The 3D evaluation technique effectively revealed specific tendencies in dental students' caries removal skills. The integration of computerized assessments with traditional methods could potentially assist the instructors in delivering more objective and specific feedback to students. Further research is encouraged to investigate the impact of this assessment technique on improving student performance in selective caries removal skills.

Effect of morality or capitalist ideology in choosing dentistry as a career in Türkiye: a cross sectional study.

BACKGROUND: Previous studies have provided important findings on the profession of dentistry and the motivators for choosing dentistry. This study has attempted to contribute to this accumulation by using a sociocultural perspective and interpreting the relationships among motivators from this perspective in a large Turkish sample. The aim of this study was to investigate what motivates dental students to choose dentistry as a career in Türkiye. METHODS: First-year dental students from different dental schools were included in a descriptive cross-sectional study. The questionnaire included sections covering demographics, motivators and career satisfaction. A total of 919 students from 29 different state dental schools and four private dental schools participated. Descriptive statistics such as percentages, means and standard deviations were used to summarize the sociodemographic information and the distribution of the motivators. Factorial analysis was carried out for the structural status of the questionnaire items. The relationships between the motivators were analyzed using Pearson's correlation. RESULTS: Among the 919 students, 64.2% were female, and 35.8% were male. Half of them chose dentistry after seeing their higher education institution's examination results, while the other half had already considered it a career during their preuniversity years. Communicating with people, artistic skills, and helping others were the main motivators for students to choose dentistry as a career in Türkiye, and students' overall career satisfaction was moderately high. The strongest correlations were between communication with people and benefits (r =.74), between communication with people and helping others (r =.71), between communication with people and artistic skills (r =.66), between artistic skills and benefits (r =.69), between artistic skills and helping others (r =.65), between dental experience and benefits (r =.51), between dental experience and helping others (r =.50), and between benefits and helping others (r =.71). CONCLUSION: Helping others, artistic skills, communicating with people, and benefits were the most important factors motivating dental students to choose a career, and positive relationships were detected between these four factors. This information may help to develop more effective career guidance and mentorship strategies for dental students.

Self-reported preparedness of final year undergraduate dental students and interns in Saudi Arabia: a multi-institutional study.

BACKGROUND: Contemporary undergraduate dental education aims to equip the dental students with clinical competence, empathy, and professionalism to enable them to deliver safe and effective dental care to the communities. The purpose of this study was to assess the self-reported preparedness of final year dental students and interns at three Saudi dental institutions, using the pre-validated Dental Undergraduates Preparedness Assessment Scale (DU-PAS). METHODS: A cross-sectional study design was employed to assess the self-reported preparedness of the participants using the DU-PAS. Following ethics approval, a probability sampling technique was used to recruit undergraduate dental students and interns from three dental institutions in Saudi Arabia. The data was collected online on Google Forms and all participants provided their consent to participate in the study prior to providing their responses to DU-PAS. RESULTS: Responses were received from 397 participants including 171 males and 226 females yielding a response rate of 60.3%. The total mean score of the participants was 81.85 ± 13.11. Although higher scores were reported in males, the interaction between gender and DU-PAS scores were not significant. Interaction between DU-PAS scores and stage of education showed significant effect of the stage of education with interns reporting higher overall scores. The participants reported that they were able to perform most clinical procedures independently. However, low confidence was reported in performing multi-rooted endodontics, fabrication of removable dentures and orthodontic assessment. The participants also expressed their confidence in a wide range of behavioural attributes related to communication, teamworking and professionalism. However, lack of experience was noted in referral for oral cancer, interpreting research, and evaluation of new dental products using an evidence-based approach. CONCLUSION: The study provides useful insights into the self-reported preparedness of undergraduate dental students and interns in three dental institutions. While the overall preparedness of the participants was comparable to their international peers, the findings underscore the need for further enhancements to the teaching and training of undergraduate students particularly in multirooted endodontics, removable prosthodontics and orthodontics.

Radiographic Assessment of 121 Glass Fiber Post Procedures in 32 Patients Aged 21-60 Years Performed by 6th-Year Dental Students During the 2022-2023 Academic Year at the College of Dentistry, Jazan University, Saudi Arabia.

BACKGROUND The restoration of endodontically treated teeth (ETT) and severely damaged teeth has been a concern of clinicians. Glass Fiber Post (GFPs) combine the strength of carbon fiber posts with the esthetic appearance of glass to resemble natural dentin during dental restoration procedures. This radiographical study assessed the GFP carried out by students enrolled in the Clinical Comprehensive Course at the College of Dentistry, Jazan University. MATERIAL AND METHODS A total of 32 patients treated by 18 6th-year dental students with 121 GFPs were assessed in this cross-sectional radiographic study. The assessment covered tooth type, arch, post-to-root width, length of post in relation to the crown and root lengths, amount of remaining gutta percha (GP), and gap between GP and post. Data were analyzed using SPSS, and associations between variables were determined using the chi-square test. RESULTS Maxillary teeth were the most frequently restored with posts (88.4%) with most being (58.7%) anterior teeth, and 50.4% of posts had widths that were one-third that of the root. The percentage of posts was twice (71.1%) or equal to (26.4%) the crown length, whereas two-thirds of the tested GFPs were >5 mm of the remaining GP. Significant differences were observed in location and position of teeth with post width, post length in relation to crown or root length, and amount of remaining GP, with P values of 0.018, 0.000, and 0.001, respectively. CONCLUSIONS The assessed radiographs revealed that the performance of sixth year students in accomplishment GFP radiographically was satisfactory and within the values recommended in the literature.

Evaluation of the efficacy of a simulation model used in oral and maxillofacial surgery education.

BACKGROUND: The traditional teaching methods of dental education are gradually being replaced with futuristic education methods based on the usage of educational tools such as mannequin-based simulation models and virtual reality. However, the effectiveness of mannequin-based simulation models as a learning method in the field of oral surgery remains unclear. This study aims to investigate the efficacy of training on a tooth extraction model (TEM) in view of undergraduate dental students' experience and perception of their education. METHODS: A quasi-experimental trial was implemented with two consecutive year classes, totaling 136 students at the Dentistry Faculty of Altinbas University, Turkiye. Two cohorts were created from dental students in the classes of 2023 and 2022 graduates. Cohort 1 (n = 71) received 14 h of theoretical education followed by 10 h of preclinical education on TEM. Cohort 2 (n = 65) received only 14 h of theoretical education. An anonymous questionnaire was prepared with four main sections including the preferences of learning style, participants' perceptions of the preclinical training methods, the students' competency and free text comments. Students' opinions were quantified with both 7-point Likert scales and thematic analysis. Anxiety levels were measured with the interval scale of anxiety response (ISAR). Descriptive statistics, inferential statistical and thematic analyses were conducted according to survey responses. Student characteristics were summarized and compared for two cohorts using a t-test. For all statistical analyses, the significance level was set atP ≤ 0.05. RESULT: Cohort 1 was more comfortable with sequential motions performed with the forceps (P = 0.033) and felt more ready for their first clinical tooth extraction experience (P = 0.028). Cohort 2 showed a significantly higher preference for textbooks among supplementary materials (P = 0.04); however, they tended to exhibit lower self-confidence and higher anxiety levels, though without any statistical significance (P > 0.05). CONCLUSION: It is clear that the students who have yet to start seeing patients benefit from increased practice with training models, which adequately reflect and represent real-life situations encountered in everyday practice.

Dental students in an orthodontic course flipped classroom: A semi-experimental study on knowledge, practice, attitude, and satisfaction.

OBJECTIVE: The purpose of this study was to determine the students' attitudes before and after the flipped classroom, and the effectiveness of this method to promote the students' lateral cephalograms tracing abilities, students' satisfaction and their final exam scores. MATERIALS AND METHODS: This is a single-group quasi-experimental research conducted on dental students of Shiraz University of Medical Sciences (SUMS), Iran in 2019. The intervention was carried out in a blended learning approach with the flipped classroom model. Thirty-five fourth-year dental students participated in a flipped classroom held during a semester for the lateral cephalograms tracing course. The students were provided with the educational materials before the class time through multimedia learning tools and the class time was devoted to discussions. The students were asked to fill out four questionnaires (pretest/posttest attitudes, pretest/posttest self-assessments of theoretical knowledge and practical skills in cephalograms, posttest of satisfaction from quality of the course, and posttest of students' views about effectiveness of blended learning tools) and final exam scores of students. RESULTS: Students' attitudes toward e-Learning were improved after the flipped classroom and the quality of this method was acceptable to the students (p < .001). Their self-assessment of theoretical knowledge and practical skills were promoted (p < .001). While all blended learning tools averaged more than the cut-off-point, short lecture (5.11 ± 0.98) and live feedback (4.98 ± 1.07) were considered to be the most efficient interactive tools. CONCLUSION: It seems that the flipped classroom has a positive effect on increasing students' knowledge, attitude, and satisfaction. In general, this method of learning seems to be favored by dental students. CLINICAL SIGNIFICANCE: The findings showed that blended learning had a positive effect on increasing knowledge, performance, and satisfaction among dental students. Therefore, blended learning as a reliable method might be used in training dental students.
