“…In summary, and as concluded by a series of systematic reviews over the last decade, [39][40][41][42][43][44][45][46][47] orthodontic forces result in biological responses in the dental pulp including initial decreased pulpal blood flow, reactive hyperaemia, increased pulpal cellular responses, pulpal fibrosis, interference with pulpal sensibility and increase in the expression or activity levels of certain enzymes and neuropeptides associated with inflammation. Generally, these responses appear to be transient and temporary, and usually reversible, [42][43][44][45]47 if forces are within the physiological limits for the particular clinical scenario.…”

“…In an early case report, Rotstein and Engel 55 speculated that trauma related to a severe overjet may have predisposed the pulp to necrosis once OTM was commenced. Two systematic reviews indicated that there was some evidence for an increased risk of pulp necrosis in teeth with a history of trauma after OTM 41,46 whereas other reviews [56][57][58] indicated that there was no evidence to draw such a conclusion. Closer inspection of the main studies cited that claimed an increased risk [59][60][61][62][63] shows that the early report 59 was based only on the non-response to EPT in 7 of 96 children with no mention of clinical signs and symptoms.…”

The literature is replete with articles describing the many and varied interactions between endodontic treatment and orthodontic tooth movement (OTM), often reporting conflicting views and findings, which creates confusion for clinicians. Original research and review articles have described aspects such as apical root resorption and potential pulpal complications of teeth related to OTM. Some interactions are of relatively minor clinical significance, whilst others may have adverse consequences. A history of dental trauma before or during OTM further complicates the interactions. This review re‐assesses the historical literature on endodontic‐orthodontic interactions in light of more recent research and presents guidelines for managing clinical situations involving both disciplines. © 2023 Australian Dental Association.

ObjectiveTo evaluate the efficacy of microchips and 3D microsensors in the measurement of orthodontic forces.MethodsThrough September 2023, comprehensive searches were conducted on PubMed/MEDLINE, SCOPUS and SCIELO without restrictions.ResultsAfter removing duplicate entries and applying the eligibility criteria, 23 studies were included for analysis. All the studies were conducted in vitro, and slightly more than half of them were centred on evaluating orthodontic forces exerted by aligners. Eight utilized microchips as measurement tools, while the remaining studies made use of 3D microsensors for their assessments. In the context of fixed appliances, key findings included a high level of agreement in 3‐dimensional orthodontic force detection between simulation results and actual applied forces. Incorporating critical force‐moment combinations during smart bracket calibration reduced measurement errors for most components. Translational tooth movement revealed a moment‐to‐force ratio, aligning with the bracket's centre of resistance. The primary findings in relation to aligners revealed several significant factors affecting the forces exerted by them. Notably, the foil thickness and staging were found to have a considerable impact on these forces, with optimal force transmission occurring at a layer height of 150 μm. Furthermore, the type of material used in 3D‐printing aligners influenced the force levels, with attachments proving effective in generating extrusive forces. Deliberate adjustments in aligner thickness were observed to alter the forces and moments generated.ConclusionsMicrochips and 3D sensors provide precise and quantitative measurements of orthodontic forces in in vitro studies, enabling accurate monitoring and control of tooth movement.
