Longitudinal Analysis of Mandibular Condylar Growth Trajectories in Growing Patients

This study aimed to analyze the continuous morphological changes of the mandibular condyle during growth using longitudinal panoramic radiographic data and visualize these changes as growth trajectories. A total of 100 growing patients with 564 panoramic radiographs obtained betw...

Gas-driven needle-free dental injection enables tunable and predictable soft-tissue penetration: high-speed kinematic and micro-computed tomography validation

Needle-free jet injectors are a promising alternative to conventional dental needles, particularly for patients with injection-related fear. However, the actuation mechanism can substantially affect jet formation, delivery consistency, and tissue penetration. This study compared...
