Introduction and Objective Dentists experience high amounts of professional stress beginning with their student years in dental school. This stress, given its early onset, may negatively impact the personal and professional lives of these individuals, as well as the quality of their clinical work. We sought to create an objective scale to evaluate the levels of stress in students at different stages of their education, as well as in practicing physicians. Materials and Methods Thirty dental students participated in this study, with 10 students each selected from junior, mid-senior, and senior classes. They were randomly divided into two groups in which one group was subjected to stressors while the other group was not. JINS MEME ES_R (JINS) smart glasses and Garmin Vivoactive 3 smartwatches were used to obtain data, including electrooculography (EOG), heart rate (HR), and accelerometer (ACC) and gyroscope (GYRO) feedback, while the subjects performed a dental exercise on a phantom tooth. Results The heart rates of more experienced students were lower than those of the junior students. The EOG, ACC, and GYRO signals showed multiple differences in the measurement of amplitudes and frequency of episodes. Conclusion Our pilot results show that electronic tools, like smart glasses with software and sensors, are useful for monitoring the stress levels of dental students in preclinical operating conditions. We would like to further assess the stress levels in students performing dental procedures on phantom teeth and in later clinical interactions with patients.

Abstract The present study was designed to determine the prevalence of broken appointments of female and male patients scheduled for third, fourth, and fifth year dental students. Data was obtained from computers used for patient scheduling at two campuses of the dental college. The proportion of broken appointments at these facilities was computed using the X2 -test to determine a difference between males and females. Results showed that male patients (14.9%) had a higher proportion of broken appointments than female patients (12.4%). Such differences among gender was statistically significant (p=4.218). The highest percentage of broken appointments was during December of 2001. Thirty four percent of these broken appointments were in the Restorative Clinic at the Darraiyah Campus (DUC) serving primarily male patients and 24% in the Removable Partial Denture Clinic at the Malaz Campus (MUC) serving only female patients. It was concluded the percentage of broken appointment s is considered to be unacceptable because of the negative impact on student learning and, ultimately, their academic progress.

SUMMARY Objective: The purpose of this study was to evaluate the effectiveness of five different polishing systems on a computer-aided design and computer-aided manufacturing (CAD/CAM) polymer-infiltrated ceramic-network restoration with nanoscale assessment using atomic force microscopy (AFM) and visual assessment performed by dental school senior students and faculty members. Method: Forty-eight full coverage crowns were milled out of polymer-infiltrated ceramic-network CAD/CAM blocks (Vita Enamic) for polishing with one company proprietary, two ceramic and two composite polishing systems. The prepared crowns were divided into six groups: (1) no polishing (control); (2) polishing with Vita Enamic Polishing Kit (VEna); (3) polishing with Shofu Porcelain Laminate Polishing Kit (SCer); (4) polishing with Brasseler Dialite Feather lite All- Ceramic Adjusting & Polishing System (BCer); (5) polishing with Shofu Composite Polishing Kit (SCom); and (6) polishing with Brasseler Composite Polishing Kit (BCom). The polished crown surface topography was observed, and surface roughness and area were measured with AFM. In addition, polished crowns were visually assessed by 15 senior dental students and 15 dental school faculty members. Results: All polishing treatments significantly reduced the surface roughness and area of the crown compared with the control. SCom and BCom showed significantly higher surface area than VEna, and the SCer and BCer groups were intermediate, showing no significant difference from either VEna or SCom and BCom. There were no significant differences in surface roughness between any of the systems. Dental students and faculty members classified the groups polished with VEna, SCer, and BCer groups as clinically acceptable, and they selected BCer group as the best polished restorations and the control group as the least polished restorations. Conclusions: Ceramic and composite polishing systems produced similar polishing results as that observed using a company proprietary polishing system. However, effectiveness for polishing using a company proprietary and ceramic polishing system tends to be higher than composite polishing systems.

Mercury (Hg) is widely used in the dental working environment, exposing dental practitioners and assistants to potentially toxic Hg vapors. Concentrations of Hg in vapor and in particulate matter (PM10) were measured in the Dental Simulation Laboratory (DSL) and in the Dental Clinic (DC) at the School of Dentistry, University of Puerto Rico. PM10 samples were collected over a 36-h period and Hg vapor was collected for eight-hour periods. PM10 mass was determined gravimetically and Hg (bound to PM10 and vapor) was extracted and analyzed by atomic absorption. Indoor levels of PM10 in the DSL ranged from 9.2 to 41.6 μg/m3 and 35.0 to 68.2 μg/m3 in the DC. Levels of particle-bound Hg ranged from 0.1 to 1.2 μg/m3 and in vapor 1.1 to 3.3mg/m 3 at the DSL; the DC levels ranged from <0.01 to 0.2 μg/m 3 for particle bound Hg and 13.6 to 102.7 μg/m3 in vapor. PM10 concentrations were below Indoor Air Quality suggested limits for total dust (100 μg/m3). Levels of mercury bound to PM 10 were low; however, mercury vapor was several times higher than the suggested OSHA (permissible exposure limit — 100 μg/m3) in the DSL.
