Purpose: To assess the impact of transformations in pediatric dental clinics following reopening during the COVID-19 pandemic on pediatric dentistry procedures performed by dental students.

Methods: Data were collected from electronic clinical records of Integrated Dental Clinical disciplines (I, II, III, and IV) from 2018 to 2023. The procedures were categorized into phases: prevention/stabilization, restorative/definitive, and maintenance. The data were analyzed descriptively and by t-test considering the pre-pandemic and pandemic periods (α = 5%).

Results: During the pandemic, Integrated Dental Clinics I and III saw increased prevention/stabilization procedures percentages (92.4% and 74.3%) compared to pre-pandemic (84.9% and 70%), while Integrated Dental Clinic II and IV saw a decline (76.6% and 66.1%) compared to pre-pandemic (79.1% and 67.9%). Restorative/definitive procedures decreased in Integrated Dental Clinic I and III (5.5% and 20.3%) from pre-pandemic period (10% and 24.1%) but increased in Integrated Dental Clinic II and IV (18.3% and 26.2%) from pre-pandemic (15.3% and 25%). Maintenance procedures decreased in Integrated Dental Clinic I, II, and III (2.1%, 5%, and 5.4%) compared to pre-pandemic (5.1%, 5.6%, and 6%), except for Integrated Dental Clinic IV, which saw an increase (7.8% from 7.2%). Despite the percentage changes, no significant differences were found between the periods analyzed (p > 0.05). However, when considering the total procedures across all disciplines and phases, there was a significant decrease during the pandemic in phases 1 and 3 (p < 0.05).

Conclusion: Despite the changes in pediatric dentistry procedures, the transformations within the dental clinic suggest tangible benefits for the teaching-learning process and safe patient care.

Background and objective: Competency-based education is recognized for evaluating dental students' knowledge and skills. However, practical management training, which is the hands-on education and experience in managing operations and patient interactions, does not align fully with this framework. This study aims to assess professional competence and related factors among dental students using self-assessment, contributing to dental education literature, and identifying areas for improvement.

Methods: A cross-sectional study included 50 total senior dental students from a top-ranked dental school. With a response rate of 100%, data were collected using a structured questionnaire with three sections: personal information, self-assessment of professional competency, and factors influencing competency. Statistical analysis, including descriptive statistics and tests like Chi-square and ANOVA, analyzed the data.

Results: The average self-reported professional competence score was 71.15 with a standard deviation of 3.05. Associations between age, gender, grade point average (GPA), and self-reported professional competence were assessed, with no significant links found (p > 0.05). Influential factors included interaction with clinical instructors (69.24%) and interest in dentistry (67.03%). No significant differences in self-reported professional competence were observed among students residing on-campus versus off-campus.

Conclusion: Age, gender, and GPA do not significantly impact dental students' self-reported professional competence. Positive interaction with instructors and interest in dentistry contribute to skill development. Practical experience and effective educational relationships are crucial. Dental education institutions should improve clinical competence by fostering strong student-instructor relationships, increasing hands-on clinical training, and fostering student interest in dentistry.

Purpose/objective: Imposter phenomenon (IP) depicts the feeling of being a fraud. Stress and perfection are associated with IP, impairing professional and academic performance and negatively impacting mental health. The purpose of this study was to explore the prevalence of IP and perfectionism in dental hygiene students and the relationship with stress.

Methods: This study used cross-sectional survey research with a nonprobability sampling of dental hygiene students (n = 258). The study used three validated instruments: the Imposter Profile (IPP30) with six subscales, the Frost Multidimensional Perfectionism Scale Brief with two subscales, and the Perceived Stress Scale (PSS10). Descriptive, correlation, and linear regression were used for analysis.

Results: The completion rate was 74.8% (n = 193). Linear regression analysis found the competence doubt (CD) subscale of the Imposter-Profile and perfectionistic striving (PS) were the only statistically significant predictors of stress (F = 10.01, p < .001, R² = .16). CD (b = 0.36, p < 0.001) was twice as strong as PS (b = 0.15, p < 0.05) in predicting stress in dental hygiene students.

Conclusion: In this sample of dental hygiene students, the doubt about competence aspect of imposter phenomenon increased stress more than the striving for perfectionism. Faculty may minimize stress and support students by identifying the feelings associated with imposter phenomenon and highlighting student achievements to build confidence and feelings of self-efficacy.

Objectives: The purpose of the present study was to design and assess a 3D simulation model for submental flap surgery in training oral and maxillofacial surgery (OMFS) residents.

Methods: This quasi-experimental study involved a total of 20 OMFS residents attending and was conducted from September 2023 to December 2023. A 3D submental flap surgical phantom was designed using Mimics V.21 software and printed using fused deposition modeling technology. Participants were first tested on their knowledge of submental flap surgery before being randomly assigned to experimental or control groups. The experimental group received a lecture and demonstration using the developed phantom, while the control group had traditional lecture education only. Afterward, the same test was administered to all participants post-training. Pre- and post-test scores were calculated and compared between the two groups. p-Value < 0.05 was considered statistically significant.

Results: The average pre-intervention test scores in the control and experimental group, were 2.5 ± 1.43 and 3 ± 0.816, respectively (p = 0.35). Post-intervention, the experimental group exhibited significantly higher exam scores compared to the group who had only received academic lecture training (6.9 ± 0.87 vs. 4.9 ± 0.99) (p < 0.001). Irrespective of the applied teaching method, both groups showed a significant increase in exam scores after receiving submental flap training (p < 0.001 for both groups, paired-sample t-test).

Conclusion: The use of the developed submental flap phantom model significantly improved OMFS residents' test scores and knowledge of the surgical technique, suggesting its potential integration into the conventional resident training curriculum.

Purpose: This study examined whether pediatric dentists who participated in a pediatric dental residency program focusing on disease prevention and management training and screening for social determinants of health (SDOH) were applying these principles to their professional practice upon graduation.

Methods: Using a cross-sectional study design, a one-time-only online survey was disseminated to 75 pediatric dentists who graduated from the University of California, Los Angeles's training program between 2012 and 2022. The 21-item survey included questions on demographics, patient population characteristics, and application of preventive dentistry and SDOH to their professional practice. Descriptive statistics and bivariate analyses were used to assess survey items.

Results: The survey response rate was 64%. Over two-thirds (67%) of alumni reported accepting Medicaid, 34% saw patients in a medically underserved area and all reported seeing children with special needs in their practice. Strategies used to address SDOH in their practice included providing anticipatory guidance (98%) and educating families on oral disease prevention and screening for SDOH (96%). Alumni accepting patients with Medicaid/public health insurance were more likely to address SDOH in their practice, such as assisting patients with filling out Medicaid paperwork (p < 0.05), conducting outreach to underserved communities (p < 0.05), and using interpreters in their practice (p < 0.01) in comparison with alumni not accepting patients with Medicaid/public health insurance.

Conclusion: This study demonstrated that a pediatric dental residency program may be successful in training residents to educate children, families, and special needs patients on disease prevention and management in an ethical and culturally sensitive manner and screen for SDOH during patient visits.

Objective: Dental materials science is one of the fundamental disciplines in stomatology, encompassing clinical areas such as orthodontics, prosthodontics, and endodontics. Due to its extensive knowledge base, strong professional nature, and wide scope, teaching dental materials science presents a challenge. This study aimed to enhance the application of dental materials science in oral teaching by comparing the effectiveness of different teaching methods.

Methods: This research project was evaluated by the Xi'an Jiaotong University Committee on Human Subjects Research and approved as exempt research. A total of 56 clinical stomatology students from the first year and second year cohorts at the Stomatology Hospital of Xi'an Jiaotong University were selected for the study. The first year cohort served as the nonteaching reform class, while the second year cohort formed the teaching reform class. The impact of the teaching reform was assessed through a questionnaire survey and final examination results.

Results: The questionnaire survey of students in the teaching reform class indicated a significant improvement in their interest in professional courses and overall satisfaction with the teaching. Additionally, the final examination results revealed a significantly greater rate of excellence among students in the teaching reform class than among those in the nonteaching reform class, with no students failing.

Conclusion: The use of diverse teaching modes can enhance the quality and effectiveness of dental materials science instruction, offering a new approach for improving teaching in this discipline.

Objectives: Temporomandibular disorders (TMD) affect individuals undergoing increased stress, for example, dental professionals. No study to date has compared dental students and faculty in TMD manifestation. This cross-sectional study compared prevalence, risk factors, and impact on daily activities of self-reported TMD signs/symptoms between dental students and faculty at a predoctoral dental school, and between preclinical (first- to second-year) and clinical (third- to fourth-year) students.

Methods: A REDCap survey was sent to dental students and faculty, assessing TMD signs/symptoms (TMD Symptom Questionnaire), pain intensity (Chronic Graded Pain Scale), jaw function (Jaw Function Limitation Scale), parafunctions (Oral Behavioral Checklist), previous TMD treatments, anxiety/depression symptoms (Patient Health Questionnaire), perceived stress (Perceived Stress Scale), and sleep quality (RU-SATED Scale). Outcomes were compared between groups using chi-square and t-tests, adjusting for covariates with analyses of covariance (ANCOVA).

Results: Data derived from N = 145 participants (N = 108 students, N = 37 faculty). Dental students reported significantly higher prevalence (90.1% vs. 75.7%, p = 0.020) and greater number of TMD signs/symptoms (5.3 ± 3.5 vs. 3.0 ± 2.7, p < 0.001) compared to faculty. Students reported significantly more parafunctional activities (p = 0.000), jaw-strain episodes (prolonged mouth opening, p = 0.007), higher stress level (p = 0.008), and lower sleep quality (p = 0.002) than faculty. Difference in number of TMD signs/symptoms was maintained after adjusting for stress, sleep quality, and parafunctional/jaw-strain activities. Clinical students utilized significantly more often evidence-based TMD treatment compared to preclinical students.

Conclusions: High prevalence of self-reported TMD was observed among dental students and faculty, with students reporting higher prevalence and impairment despite working in the same environment. Findings underscore the importance of education on preventive measures early in dental training to address contributing factors and TMD management.

Purpose: This survey aims to assess the understanding, viewpoints, and methods employed by undergraduate dental students in the fourth and fifth grades regarding broken endodontic instruments in root canal procedures.

Methods: A survey comprising 27 questions across three sections-demographic information, practical application, and knowledge-approach-awareness inquiries-was developed. It was distributed to 282 students either in person or via a link shared through WhatsApp groups using Google Forms.

Results: Out of the total 219 respondents (77.6%), 10.6% experienced instrument breakage once during their clinical internship, while 2.8% encountered it more than once. The majority (86.7%) did not face instrument fracture incidents. Among these occurrences, it was observed that endodontic instruments were most commonly separated in molars, accounting for 51.9%. Nearly half (48.1%) of the students noted instrument breakage during the initial attempt to reach the apical part of the canal, while 55.6% reported breakage during root canal cleaning and shaping.

Conclusions: Most dental students opted to leave the separated instrument in the root canal and proceed with filling it. Enhancing students' understanding and awareness of this matter will help prevent potential complications and enable them to handle such situations appropriately when they arise.
