Background: This meta-analysis summarizes the current evidence on the intra- and inter-observer agreement between WHO and the binary grading systems used to assess epithelial dysplasia (ED).
Methods: A systematic search for observational studies that compared the level of agreement among pathologists between WHO and binary grading systems for ED was conducted using three databases: Medline, Scopus, and EBSCOhost. For the meta-analysis, summary estimations of kappa value (κ) and standard error (SE) were utilized.
Learning to Control Complex Robots Using High-Dimensional Body-Machine Interfaces.

Article Synopsis
- * In a study involving non-injured participants, the effectiveness of a high-dimensional BoMI to control a robotic arm was examined over five sessions.
- * Findings indicate that how robot control is mapped from human inputs affects learning; while joint space control is easier to start with, task space control leads to better long-term performance and learning outcomes.
Article Synopsis
- Streptococcus mutans is a key player in dental caries due to its acid production and biofilm survival, leading to a shift towards using antimicrobial Photodynamic Therapy (PDT) with Toluidine Blue O (TBO) as a potential treatment.
- The study aims to encapsulate improved TBO (ITBO) in nanoliposomes (NLITBO), analyze its properties, and assess its antibacterial effectiveness against Streptococcus mutans in lab settings.
- Results indicate that NLITBO showed effective drug loading and stability, with antibacterial activity evaluated through zone of inhibition and minimum inhibitory concentration tests using red light to enhance its effects.
This study aimed to assess the undergraduates' and lecturers' perspectives on the implementation of online learning and to compare perspectives between private and public universities. The study followed a mixed-method design and involved dental undergraduates and lecturers from two study settings in Malaysia: International Medical University (IMU), a private university, and Universiti Teknologi MARA (UiTM), a public university. All undergraduates and lecturers were invited to complete an online questionnaire with evaluative statements regarding three domains: handling, didactic benefit, motivation, and an overall assessment.

Nevertheless, to apply the knowledge acquired from studies conducted on rodents to a human context, it is crucial to consider the significant spatial and temporal parallels and differences between the oral microbiota of mice and humans. Initially, we outline the comparative physiology and microbiology of the oral cavity of rodents and humans.
