Does ultrasound stimulation attenuate root resorption of rat replanted molars and impairs tumor necrosis factor-α signaling in vitro?
Ultrasound may contribute to the reduction of the trauma-induced inflammatory reaction through impairment of the TNF-α signaling pathway. It is therefore suggested that ultrasound shows potential as a therapeutic tool to optimize the regenerative potential of periodontal tissues on replanted teeth.
Our data did not provide any evidence to support the contention that resident fatigue leads to increased medical errors. Clinical data supporting a direct relationship between resident fatigue and compromised patient safety must be demonstrated before further work hour restrictions are made. More research must be done. The JC should consider monitoring sentinel events for resident fatigue.
