Orthodontic forces are strongly associated with pain, the primary complaint among patients wearing orthodontic braces. Compared to other side effects of treatment, pain is often overlooked, limited clinical management. lead inflammatory responses in periodontium, which triggers bone remodeling and eventually induces tooth movement. Mechanical subsequent inflammation periodontium activate sensitize periodontal nociceptors produce pain. Nociceptive afferents expressing transient receptor potential vanilloid subtype 1 (TRPV1) play central roles transducing nociceptive signals, leading transcriptional changes trigeminal ganglia. molecules, such as TRPV1, ankyrin 1, acid-sensing ion channel 3, P2X3 receptor, believed mediate Neuropeptides calcitonin gene-related peptides substance P can also regulate While transmit signals brain, they known modulate alveolar periodontitis. Therefore, molecules may contribute modulation movement, currently remains undetermined. Future studies needed better understand fundamental mechanisms underlying neuroskeletal interactions orthodontics improve treatment by developing novel methods reduce accelerate movement—thereby achieving “big gains no pain” orthodontics.

Published: May 22, 2024

It is remarkable how teeth maintain their healthy condition under exceptionally high levels of mechanical loading. This suggests the presence inherent adaptation mechanisms within structure to counter constant stress. Dentin, situated between enamel and pulp, plays a crucial role in mechanically supporting tooth function. Its intermediate stiffness viscoelastic properties, attributed its mineralized, nanofibrous extracellular matrix, provide flexibility, strength, rigidity, enabling it withstand loading without fracturing. Moreover, dentin’s unique architectural features, such as odontoblast processes dentinal tubules spatial compartmentalization odontoblasts dentin sensory neurons contribute distinctive perception external stimuli while acting defensive barrier for dentin-pulp complex.
