The Journal of the Michigan Dental Association

As your practice adopts AI for hiring processes, it brings efficiency but also potential pitfalls. The increasing use of AI, such as ChatGPT, streamlines tasks like resume screening, but caution is essential. Recent executive orders emphasize safety assessments and civil rights in AI. The Equal Employment Opportunity Commission focuses on transparency and consent in recruitment AI use. Legal compliance is vital to prevent discrimination; criteria like education and experience must be applied consistently. Additionally, employee monitoring AI requires careful implementation, ensuring transparency and human oversight. While AI offers benefits, its workplace integration demands careful consideration, testing, and ongoing evaluation.

Zeitlin’S Top 200 Dental Deckades (January 2024), Benjamin D. Zeitlin

Pacific Open Texts

Pharmacology courses in any institution are information intensive with a constant, high volume of new material. With that in mind, the standards that the American Dental Education Association set for Pharmacology include that: “the student must identify the influences drugs taken for non-dental purposes may have on a proposed treatment (…) and the student must recognize therapeutic agents used in the routine practice of clinical dentistry.” This requires that students at a minimum, recognize common drugs and know their major implications for dental therapy.

This learning tool has been created to address the drug recognition aspect of that standard.

A Pthrp Gradient Drives Mandibular Condylar Chondrogenesis Via Runx2, C Tsutsumi-Arai, Y Arai, A Tran, M Salinas, Y Nakai, S Orikasa, W Ono, N Ono

Faculty, Staff and Student Publications

The mandibular condylar cartilage (MCC) is an essential component of the temporomandibular joint, which orchestrates the vertical growth of the mandibular ramus through endochondral ossification with distinctive modes of cell differentiation. Parathyroid hormone–related protein (PTHrP) is a master regulator of chondrogenesis; in the long bone epiphyseal growth plate, PTHrP expressed by resting zone chondrocytes promotes chondrocyte proliferation in the adjacent layer. However, how PTHrP regulates chondrogenesis in the MCC remains largely unclear. In this study, we used a Pthrp-mCherry knock-in reporter strain to map the localization of PTHrP+ cells in the MCC and define the function of PTHrP in the …
