Delayed tooth movement in Runx2+/− mice associated with mTORC2 in stretch-induced bone formation

Bone Reports, 2020
Runt-related transcription factor 2 (Runx2) is an essential transcription factor for osteoblast differentiation, and is activated by mechanical stress to promote osteoblast function.

Retrograde nerve growth factor signaling modulates tooth mechanical hyperalgesia induced by orthodontic tooth movement via acid-sensing ion channel 3

International Journal of Oral Science, 2021
Orthodontic tooth movement elicits alveolar bone remodeling and orofacial pain that is manifested by tooth mechanical hyperalgesia. Nerve growth factor (NGF) is upregulated in periodontium and may modulate tooth mechanical hyperalgesia.

Leptin levels in gingival crevicular fluid during orthodontic tooth movement

Journal of Pharmacy and Bioallied Sciences, 2021
Aim: To evaluate the levels of leptin in gingival crevicular fluid (GCF) during orthodontic tooth movement and to find the role of leptin as a mediator for tooth movement. Materials and Methods: GCF was collected from 25 subjects and the levels of leptin

Sensory Nerve‐Derived CGRP Controls Osteoclastogenesis by Limiting Macrophage Bioenergetics in Bone Repair

Advanced Science, EarlyView.
Sensory nerves help bones heal. This study shows that the neuropeptide CGRP, released from sensory nerves, slows down macrophage energy production, preventing excessive bone breakdown. By revealing this nerve–immune–metabolism connection, the work provides new insight into how the body balances bone repair and opens doors to targeted treatments ...
