Background: This study aimed to evaluate the efficacy of external vibrating devices and counterstimulation on a child's dental anxiety, apprehension, and pain perception during local anesthetic administration. Methods: This was a prospective, randomized, parallel-arm, single-blinded interventional, clinical trial. One hundred children aged 4-11 years, requiring pulp therapy or extraction under local anesthesia (LA), were recruited and allocated equally into two groups (1:1) based on the interventions used: Group BD (n = 50) received vibration using a Buzzy<sup>®</sup> device {MMJ Labs, Atlanta, GE, USA} as a behavior guidance technique; Group CS (n = 50) received counterstimulation for the same technique. Anxiety levels [Venham's Clinical Anxiety Rating Scale (VCARS), Venham Picture Test (VPT), Pulse oximeter {Gibson, Fingertip Pulse Oximeter}, Beijing, China)] were assessed before, during, and after LA administration, while pain perception [Wong-Baker Faces Pain Rating Scale (WBFPS), Visual Analogue Scale (VAS)] was evaluated immediately after injection. Statistical analysis was performed using the Student's t-test to assess the mean difference between the two groups and the repeated measures ANOVA for testing the mean difference in the pulse rates. Statistical significance was set at P < 0.05. Results: Significant differences in mean pulse rate values were observed in both groups. In contrast, the children in the BD group had higher diminution (P < 0.05), whereas the mean VCARS and VPT scores were conspicuous (P < 0.05). Based on the mean WBFPS and VAS scores, delayed pain perception after LA injection was more prominent in the BD group than in the CS group. Conclusion: External vibration using a Buzzy<sup>®</sup> device is comparatively better than counterstimulation in alleviating needle-associated anxiety in children requiring extraction and pulpectomy.

Objective: This study identifies the critical ergonomic requirements and their hierarchical structures that need to be addressed during the evolution from traditional industrial robots to collaborative robots. It also delves into how the relative importance of each user requirement changes with the evolution of technology. Background: User-centered design is becoming increasingly crucial as technological advancements enable industrial robot systems to perform diverse and complex interactions. Therefore, it is necessary to identify how the characteristics of user needs change as technology advances. Method: We conducted a systematic literature review, selecting 30 articles using the PRISMA method to identify ergonomic requirements. We then mapped the user requirements to quality characteristics and found the frequencies. Subsequently, we carried out Chi-square tests to determine if there were significant differences in the frequency of occurrences for the user requirements over time. Results: The literature review identified 17 user requirements. Our findings revealed that the frequency of quality characteristics mentioned related to usability and enjoyment increases with the advancement of robotics technology. However, all the hypotheses we formulated to show the relationship between the evolving importance of each user requirement and technology maturity were found to be invalid statistically. Conclusion: As the level of collaboration of industrial robots evolves, the importance of user requirements is changing. In the past, factors like functionality, performance, and safety were the primary focus, but as technology advances, user requirements related to usability and enjoyment gain greater importance. Therefore, these attributes should be integrated into the development phase for a user-centered design approach in the future of collaborative robot systems. Application: Our work provides insight to developers into the user requirements that should be considered for effective interactions between humans and collaborative robots. Through this study, we hope to see collaborative robots developed with a direction of improving the user experience and increasing overall user acceptance.

Background: This study aimed to determine the efficacy of Physics Forceps in pediatric dental extractions. Methods: This was a double-blind, randomized controlled trial with a parallel-arm design and identical allocation ratio (1:1). Children (n=104) were randomly divided into two groups for extraction of mandibular primary teeth (group I: Physics Forceps; group II: conventional forceps). The outcome variables assessed in the study were the time taken for extraction, pre- and postoperative anxiety (using RMS pictorial scale), incidence of fractured teeth, and postoperative pain on the first and third days (using the Wong-Baker faces pain scale). Results: A significant reduction (P < 0.001) in intraoperative time, anxiety, and incidence of tooth fracture was confined to group I. The pain significantly reduced from the first to the third postoperative day in both groups, but the mean reduction in RMS scores in the physics forceps group was far better than that in the conventional forceps group. Conclusion: Physics Forceps aid in extraction of primary teeth with minimal trauma to supporting structures, as well as reducing anxiety in the pediatric population.
