Evaluation of Dentistry Students’ Perspectives of Specialization in Restorative Dentistry

Aim: The aim of this study was to evaluate the perspectives of the students studying at the faculty of dentistry on the specialization in the field of restorative treatment. Materials and Methods: A total of 139 students, comprising 4th and 5th graders enrolled at the XXX University Faculty of Dentistry, participated in the study. Of these, 71 students were in the 4th grade, while 68 were in the 5th grade. Students were administered a 10-question questionnaire about their evaluation of specialization in dentistry. The data collected was subjected to statistical analysis using the chi-square test. The statistical significance of the findings is at a level of p<0.05. Results: The most popular specialty in dentistry is Oral and Maxillofacial Surgery, with 45.3% of respondents selecting it as their first choice. The majority of respondents, at 66.9%, reported that they first became aware of the Restorative Dentistry department within the preclinical department. According to the survey, 47.5% of the students stated that the Restorative Dentistry department was primarily influenced by their clinical experience. Conclusion: It is widely acknowledged that the preclinical period is a critical juncture in shaping dental students' initial impressions of various specialties. Furthermore, a range of factors, including clinical exposure, income expectations, and personal interests, play a significant role in determining the specialty that a student may choose to pursue.

Introduction of Laboratory Endodontics: Evaluating the Perception of the Undergraduate Clinical Dental Students at a Nigerian University

Background: Root canal treatment (RCT) forms a  part of the requirements for graduation for dental students. The students are expected to perform the procedure during their clinical training. However, most students are presented to the clinic without formal laboratory practical training.
 Aim: To introduce laboratory endodontic training and evaluate the perception of Nigerian undergraduate clinical dental students about the program.
 Methodology: A two-day hands-on training on RCT was done for a set of final-year dental students in the operative technique laboratory of the Department of Restorative Dentistry of the Institution. The training included taking the participants through all the steps involved in RCT. The participants performed all the stages of RCT on extracted lower molar teeth mounted on a phantom head with paraffin wax. Each student performed the two methods of biomechanical preparation taught: manual and rotary instrumentation, and later evaluated the training in terms of confidence and preparation for clinical exposure.
 Result:  Twenty-one (53.9%) students within the age range of 23 to 30 years and a  mean age of 25.4±1.7years completed the program. The majority, (81%) of the participants claimed the hands-on demonstration was very helpful in performing the procedure, and all submitted it will help their confidence during clinical exposure to RCT. The participants further suggested the incorporation of training into the regular school program.
 Conclusion:  The laboratory endodontic hands-on training was accepted by all the participants, and it was opined that it will boost their confidence in performing the procedure in the clinic.

Role of endodontic treatment related signs for the forensic odontology practice considering real-life quality of comparable radiographs

Background. Real life quality of periapical radiographic images widely varies, while also periapical radiographs not always have been taken at the same angulation, especially in multirooted tooth cases, which in turn potentially may limit the value of obtained information received during endodontic treatment for the further comparative dental identification.
 Objective. To objectify possibility of using real-life quality periapical radiographs obtained during endodontic treatment for the comparative dental identification.
 Materials and Methods. Research was organized in the form of cross-sectional hospital-based study. Copies of ten pairs of selected radiographs were distributed for the Set 1 (simulation of ante-mortem images), which contained 10 radiographs of before root canal treatment, and Set 2 (simulation of post-mortem images), which contained 10 radiographs of after endodontic interventions. Set 1 and Set 2 images were randomized, and structured via Google Form, and five teaching assistants from the Department of Restorative Dentistry were asked to match the images through provided Google Form. 
 Results. The range of 50-80% correct pre- and post-treatment images matching levels were registered among five operators. The mean correct matching level reached 68.0 ± 7.2%. Experience within endodontics seems to be valuable regressor regarding outcome performance (p < 0.05), while additional Radiology specialization did not significantly improved performance level for matching pre- and post-treatment images (p > 0.05). Operator graded 5 out of 10 images pair as relatively easy to match, 2 images – as moderately difficult to match, and 3 images – as hard to match (Fig. 3), while their agreement on the obtained above-mentioned scores reached 0.8.
 Conclusion. Significance of endodontics within forensic odontology field in most cases dictated by using the results of periapical radiology as evidences of ante-mortem origin, while also considering the fact of root canal morphology uniqueness and individualized endodontic treatment pattern consistency both ante- and post-mortem even under the influence of various disturbing factors. On the other hand identification role of endodontic signs may be diminished within the absence of proper quality radiographs, or when such were provided at critically different angulations, while also when endodontic-related evidences could not be supported by dental records.

A survey on utilization and barriers of digital removable prostheses in the US dental education.

Gaining knowledge on the extent of digital technology implementation in dental education and the barriers to it will help inform future directions to promote the use of such technology and will enhance dental education. This study aimed to investigate the utilization of digitally fabricated removable prostheses and the potential obstacles to implementing such technology in US dental schools. A survey was developed and distributed to the restorative dentistry department chairs and postdoctoral prosthodontic program directors. The survey delivery protocol included follow-up emails 1 week, 3 weeks, and 4 weeks after the initial email. The collected data were analyzed descriptively. The response rate was 85% and 45% for predoctoral and postdoctoral prosthodontic programs, respectively. The results showed that 88.06% of the predoctoral programs and 95.65% of the postdoctoral prosthodontic programs implement digital complete dentures in the curriculum; however, the digital removable partial dentures implementation rate was recorded at 70.77% in predoctoral programs and 61.9% in postdoctoral prosthodontic programs. Dental schools are challenged by cost, design software limitations, IT and laboratory support, and faculty training. Multifaceted support is instrumental in further implementing digital removable prosthodontics into dental education.

Developing procedural metrics for training in class II posterior composite resin restorations: Outcomes from an international Delphi panel

ObjectiveThe objective of this study was to develop and operationally define procedural performance metrics for the Class II posterior composite resin restoration procedure and to obtain face and content validity through a consensus meeting. MethodsA Metrics Group consisting of 4 experienced Consultants in Restorative Dentistry, an experienced member of staff from the Restorative Dentistry department in CUDSH and a senior behavioural scientist and education/training expert deconstructed the performance of the Class II posterior composite resin restoration and defined performance metrics. At a modified Delphi meeting, 20 experts in the field of Restorative Dentistry from 11 different Dental Institutions critiqued these metrics and their operational definitions before reaching consensus. ResultsInitially performance metrics consisting of 15 Phases, 45 steps, 42 errors and 34 critical errors were identified that characterize the performance of the Class II posterior resin composite procedure. During the Delphi panel these were modified and consensus was reached on 15 Phases (with a change to the initial sequence) with 46 Steps (1 added, 13 modified), 37 Errors (2 added, 1 deleted, 6 reclassified as Critical Error), and 43 Critical Errors (9 added). Consensus on the resulting metrics was obtained and face and content validity verified. ConclusionsIt is possible to develop and objectively define performance metrics that comprehensively characterize a Class II posterior composite resin restoration. It is also possible to achieve consensus on the metrics from a Delphi panel of experts and to confirm the face and content validity of those procedure metrics.

Relationship between dental anxiety levels and oral health among dental patients in Turkey: a cross-sectional study

BackgroundThis study aimed to determine the relationship between dental anxiety and oral health in adult patients who applied to the Department of Restorative Dentistry at the Faculty of Dentistry at Suleyman Demirel University.MethodsThe study included 500 subjects. The dental anxiety levels of the patients were determined using a modified dental anxiety scale (MDAS). Information on sociodemographic details, oral hygiene and nutritional habits were recorded. Intraoral examinations of the subjects were performed. Caries prevalence of individuals was determined using the decayed, missing or filled teeth (DMFT) and decayed, missing, or filled surfaces (DMFS) indices. Gingival health was evaluated using the gingival index (GI). Statistical analyses were performed using the Mann–Whitney U, Kruskal–Wallis and Chi-square tests and Spearman correlation analysis.ResultsThe ages of the 276 female and 224 male participants ranged from 18–84 years. The median MDAS value was 9.00. The median DMFT and DMFS values were 10.00 and 23.00, respectively. The median MDAS values ​​of women were higher than those of men. Individuals who postponed their appointment had a higher MDAS median value than those who did not (Mann–Whitney U test, p < 0.05). No statistically significant correlation was found between dental anxiety level (MDAS) and GI, DMFT and DMFS index scores (Spearman correlation analysis, p > 0.05).ConclusionThe MDAS values of individuals who did not remember the reason for their dental visit were higher than those who visited the dentist for routine control. Based on the findings of this study, further research on the relationship between dental anxiety and oral health is necessary to determine the factors that pose a risk for dental anxiety and to ensure the regular benefits of dental services.

Rubber dam application in clinical practice: a study on the patient perspective

Aims: The present study aimed to elicit the views of patients, applying to our faculty for dental treatment, on rubber dam application. Methods: We recruited 250 patients, who applied to Dicle University, Faculty of Dentistry, Department of Restorative Dentistry for dental treatment, in this study upon their informed consent. Following routine clinical and radiological examinations, the patients undergoing dental procedures with rubber dams were asked to fill out a questionnaire about their views on the application. Accordingly, while the patients’ characteristics and responses to the questionnaire are shown descriptively, we sought the relationships between the categorical variables using a chi-square test. All statistical analyses were performed on the IBM SPSS 25.0 program. Results: The findings revealed that rubber dams were applied to 85.6% of the patients for the first time. In this sense, the majority of the patients (86.8%) found the treatment with rubber dams more comfortable than their previous treatments. It was discovered that the patients were uncomfortable the most when being unable to communicate with the physician during the treatment. About half of the patients (52.8%) found the most comforting aspect of rubber dam application to be the absence of water accumulation in the mouths. Besides, we found a significant association between gender and the most disturbing aspect of rubber dam application. Accordingly, while 42.6% of the female patients reported having difficulty swallowing or breathing, 40% of the male patients reported being uncomfortable when being unable to rinse their mouth and communicate with the physician during the treatment. Finally, almost all patients (93.2%) stated that they would prefer rubber dam application on their next visit. Conclusion: Despite the advantages of rubber dam application, clinicians hold a belief that patients may be disturbed by the application for various reasons. Yet, our findings showed vice versa; most patients were not disturbed by the application, and even they would prefer it on their future visit. Thus, addressing rubber dam applications in undergraduate and postgraduate education would help improve patient comfort and the quality of dental procedures.

An efficient annotation method for image recognition of dental instruments

To prevent needlestick injury and leftover instruments, and to perform efficient dental treatment, it is important to know the instruments required during dental treatment. Therefore, we will obtain a dataset for image recognition of dental treatment instruments, develop a system for detecting dental treatment instruments during treatment by image recognition, and evaluate the performance of the system to establish a method for detecting instruments during treatment. We created an image recognition dataset using 23 types of instruments commonly used in the Department of Restorative Dentistry and Endodontology at Osaka University Dental Hospital and a surgeon’s hands as detection targets. Two types of datasets were created: one annotated with only the characteristic parts of the instruments, and the other annotated with the entire parts of instruments. YOLOv4 and YOLOv7 were used as the image recognition system. The performance of the system was evaluated in terms of two metrics: detection accuracy (DA), which indicates the probability of correctly detecting the number of target instruments in an image, and the average precision (AP). When using YOLOv4, the mean DA and AP were 89.3% and 70.9%, respectively, when the characteristic parts of the instruments were annotated and 85.3% and 59.9%, respectively, when the entire parts of the instruments were annotated. When using YOLOv7, the mean DA and AP were 89.7% and 80.8%, respectively, when the characteristic parts of the instruments were annotated and 84.4% and 63.5%, respectively, when the entire parts of the instruments were annotated. The detection of dental instruments can be performed efficiently by targeting the parts characterizing them.

Bridging the gap between self-assessmentand faculty assessment of clinical performance in restorative dentistry: A prospective pilot study.

Purpose/ObjectivesThe current study was undertaken to investigate whether self‐assessment of clinical skills of undergraduate dental students could be bridged with faculty assessment by deliberate training over an extended period. A secondary aim was to explore students' perception of self‐assessment and its effect on their learning and motivation.Material and MethodsA prospective pilot study was conducted at the Department of Restorative Dentistry at Damascus University. Sixteen students participated in the study, ranging in age between 22 and 23 years. A modified Direct Observation of Procedural Skills form with a grading rubric was used to register and guide students' self‐assessment; both were pretested on four students before the study. In total, four clinical encounters were completed by each student. Students were trained on how to conduct proper self‐assessment before and after each clinical encounter. A postcourse questionnaire was used to investigate students' perception of self‐assessment.ResultsBias in self‐assessment decreased consistently after each encounter, and the difference in bias between the first (bias = 0.77) and the last encounter (bias = 0.21) was significant with a medium effect size (p = .022, d = 0.64). The percentage of disconfirming performance dimensions decreased from 39.7% to 26.9%. Students' ability to exactly pinpoint strengths improved consistently and significantly. However, their ability to pinpoint areas of improvement was volatile and showed no significant difference. Bland–Altman graph plots showed higher levels of agreement between self‐assessment and faculty assessment. Moreover, students' perception of self‐assessment was very positive overall.ConclusionsThese findings suggest the possibility that the gap between self‐assessment and faculty assessment could be bridged through deliberate training. Future longitudinal research using a larger sample size is still required to further explore whether self‐assessment can be actively bridged with faculty assessment by deliberate training.

Psychosocial impacts, perceived stress, and learning effects during the transition from preclinical to clinical dental education: Validation and translation of a questionnaire

During the first experiences of clinical treatment, dental students face various challenges. The purpose of the study is to standardize the questionnaire as a suitable tool for quantitative and qualitative evaluation of psychosocial impact, stress levels, and learning effect of dental students during the transition from preclinical to clinical education in Persian. In this cross-sectional study a questionnaire including three areas of psychosocial impact, perceived stress, and learning effect was systematically translated. In the group of experts, face validity was examined. Then, the content validity ratio (CVR) and the content validity index (CVI) were determined. The reliability of the questionnaire was determined by the test-retest method and the Cohen's Kappa coefficient. In a cross-sectional study, the psychosocial impact, stress levels, and learning effect of all students newly admitted to the endodontic, prosthetics, periodontics, and restorative dentistry departments of Shahid Beheshti Dental School (128 people) were measured. Mann-Whitney and Spearman-Rho were used for statistical analysis (P = 0.05). During the CVR and CVI evaluation, 12 statements were removed from the questionnaire, and one statement was changed. All valid statements of the questionnaire were considered reliable. The initial questionnaire was finally developed in the form of 27 items. Interest in clinical treatment and collaboration between students and faculty had the greatest psychosocial effects. The highest level of stress among students was seen in the endodontic ward (mean = 3.8). The greatest effect of learning was seen in different sections in infection control (mean >4). This study provided a standardized tool in Persian to evaluate the psychosocial impacts, perceived stress, and learning effect of dental students during the transition to clinical education and focused on the first clinical treatment experiences. One important psychosocial factor was collegiality between teachers and students. The ability to communicate well with the patient is thought to reduce stress.

The transitional care pathway following traumatic dental injuries: Patient perspectives.

The nature of complex traumatic dental injuries (TDIs) often means that management continues through paediatric to adult dental services. Evidence suggests that failure in transitional care can have detrimental impacts on health. There is limited evidence regarding patients' experiences of transitional care pathways (TCPs) in dentistry. The aim of this study was to investigate the views and experiences of the TCP from paediatric to adult care for individuals who have experienced TDIs. Semi-structured interviews were undertaken. Ethical approval was granted by the Health Research Authority and sponsored by the University of Liverpool. Inclusion criteria included individuals aged 16 to 21years old who had received care in both paediatric and adult restorative dentistry departments at Liverpool University Dental Hospital following a TDI. Five purposively sampled patients were interviewed. Thematic analysis was undertaken using NVivo. Thematic analysis identified 5main themes with regard to transitional care experience: patient-clinician communication, impact of dental trauma, feelings of uncertainty, patient personal development and transitional care planning. Feelings of uncertainty with regard to the long-term prognosis of traumatized teeth were highlighted. Clear communication and involvement of young people in decision-making was identified as a vital factor to facilitate a successful TCP experience. The involvement of young people in decision-making is essential for a successful TCP. Consideration should be given to development of TCP guidance, to allow for the provision of timely and consistent information regarding the process. Despite this, there needs to be adaptivity within the TCP to create a successful TCP for every young person.

Statistical analysis was performed using Mann Whitney U and Chi-Square tests. &#x0D; Results: According to our study, the education status, monthly income and frequency of tooth brushing affect the DMFT index value statistically significantly (p

Challenges of Oral Radiography Prescriptions During the COVID-19 Outbreak in Shiraz, Iran

Background: Considering the severity of the COVID-19 outbreak and its rapid person-to-person transmission and the challenges it has brought about in dentistry, especially in intraoral radiography, following the established guidelines in prescribing radiographs is of great prominence. Objectives: We aimed to evaluate the necessity of prescribed intraoral radiographs and to estimate the number of unnecessary prescriptions during the COVID-19 pandemic. Methods: This cross-sectional study was conducted among 143 patients with a mean age of 29.36 ± 14.11 years who visited the Radiology Department of Shiraz Dental School during the peak of the COVID-19 outbreak. Information, including gender, age, systemic diseases, referring department, and type and urgency of radiography, was collected using a checklist. Chi-squared test and Fisher’s exact test were run to assess the relationships between variables. Results: Among all the patients referred to the Radiology Department, the endodontics and oral medicine departments accounted for the highest percentage of referrals. The relationship between the necessity of radiography prescriptions and dental departments was significant (P &lt; 0.05). The lowest rate of unnecessary referrals was reported in the Department of Endodontics (13.3%), whereas the highest rate of unnecessary referrals was attributed to the aesthetic and restorative dentistry departments (73.3%). There was a significant association between dental department and the type of prescribed radiographs (extraoral/intraoral). The Orthodontics Department was the only department with more extraoral radiograph prescriptions than intraoral radiographs. One-third of the prescribed intraoral radiographs and half of the extraoral radiographs were unnecessary, with a significant difference during the pandemic (P = 0.019). Conclusions: Although there has been some success in the development of COVID-19 vaccines, this pandemic will not be easily eradicated. Therefore, it is crucial to follow the established guidelines and postpone unnecessary dental procedures to improve the safety of our community and the world in general.

Knowledge and Attitude of Recent Dental Graduates towards Smart/Bioactive Dental Composites

Aims: The purpose of this study was to explore the knowledge and attitude of dental interns vs newly graduated dentists (NGD) towards recently introduced smart/bioactive dental resin composites (SDCs).&#x0D; Study Design: Cross-sectional study.&#x0D; Place and Duration of Study: Restorative Dentistry Department, Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia from March 2018 to June 2018.&#x0D; Methodology: An online questionnaire was distributed among randomly chosen interns and NGDs in multiple countries (n= 164). The questionnaire was formulated using Google Forms. Statistical analysis of the results was conducted using percentages and frequencies and compared using Chi-square test (P&lt;0.05).&#x0D; Results: 59.15% of all respondents expressed interest in perusing restorative dentistry as a specialty.  A statistically significant lower proportion of NGDs compared to interns reported a good understanding of dental restorative materials (P=.022), hearing of SDCs (P=.033), or ever using SDCs (P=.006). 50% of NGDs reported thinking that SDCs effectively regenerate dental hard tissue was significantly (P=.016) lower than interns (70.5%). 97.6% of NGDs and 96.7% of interns reported willingness to attend a training workshop and/or a continuing education course about SDCs.&#x0D; Conclusion: Interns showed a significantly higher positive attitude towards SDCs use. Knowledge and effective use of SDCs by interns and NGDs could be improved by more training such as that offered in workshops/courses.
