“…To summarize, the literature appears to support that OTM can increase PCC in non‐traumatized teeth greater than that expected with physiological ageing, leading to a reduction in the pulp chamber dimensions and volume (i.e. calcification) 42,44,45 . The differences reported likely relate to other variables including history of trauma, OTM variables (type, duration, force levels) and individual genetic predisposition 119 .…”

“…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. 34,44,48 The systematic review by Weissheimer et al 47 evaluated only studies that assessed the pulpal status of teeth subjected to OTM using LDF or pulse oximetry.…”

“…calcification). 42,44,45 The differences reported likely relate to other variables including history of trauma, OTM variables (type, duration, force levels) and individual genetic predisposition. 119 The pulpal circulatory system of traumatized teeth with PCC seems unable to compensate for the reduction of pulpal blood flow during OTM, thus increasing the risk of pulp necrosis.…”

Endodontic–orthodontic interactions: a review and treatment recommendations

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.

Rapid maxillary expansion (RME) may change speech sound parameters due to the enlargement of oral and nasal cavities. This study aimed to systematically review the current evidence on speech changes as a side effect of RME. An electronic search was conducted in nine databases, and two of them accessed the ‘grey literature’. The eligibility criteria included clinical studies assessing orthodontic patients with maxillary transverse deficiency and the relationship with speech alterations without restricting publication year or language. Only interventional studies were included. The JBI Critical Appraisal Tool assessed the risk of bias. The initial search provided 4853 studies. Seven articles (n = 200 patients) met the inclusion criteria and were analysed. The primary source of bias was the absence of a control group in four studies. RME altered speech production by changing vowel fundamental frequency and fricative phoneme formant frequency. Shimmer and jitter rates changed in one and two studies, respectively. Two studies presented deterioration during orthodontic treatment, but speech improved after appliance removal. Despite the limited evidence, RME affects speech during and after treatment.

“…Assessment of risk of bias and overall study quality was performed using the National Heart, Lung and Blood institute’s Quality Assessment Tool for Before–After (Pre–Post) Studies With No Control Group [ 15 – 18 ]. Criteria 8 ‘Where the people assessing the outcomes blinded to the participants' exposures/interventions?’ and 12 ‘If the intervention was conducted at a group level (e.g., a whole hospital, a community, etc.)…”

Objective To review hearing and surgical outcomes after reconstructive middle ear surgery in class 4 congenital middle ear anomalies (CMEA), e.g., patients with oval- or round window atresia of dysplasia. Data sources Pubmed/Medline, Embase and Cochrane library. Review methods Articles containing data on hearing outcomes and complications after reconstructive ear surgery in class 4 anomalies were analyzed and critically appraised. The following data were included and reviewed: patient demographics, audiometric testing, surgical techniques, complications, revision surgeries and their outcomes. Risk of bias was determined, and GRADE certainty of evidence was assessed. Primary outcomes were postoperative air conduction thresholds (AC), change in AC, and success rates (closure of the ABG to within 20 dB), the occurrence of complications (most importantly sensorineural hearing loss) and the long-term stability of hearing results (> 6-month follow-up) and occurrence of recurrence of preoperative hearing loss. Results Success rates varied from 12.5 to 75% at long-term follow-up with larger cohorts reporting success rates around 50%, mean postoperative gain in AC varied from 4.7 to 30 dB and − 8.6 to 23.6 dB at, respectively, short- and long-term follow-up. No postoperative change in hearing occurred in 0–33.3% of ears, and recurrence of hearing loss occurred in 0–66.7% of ears. SNHL occurred in a total of seven ears across all studies of which three experienced complete hearing loss. Conclusion Reconstructive surgery can be an effective treatment option which should be considered in patients with very favorable baseline parameters, while also considering the substantial risk of recurrence of hearing loss, the possibility of unchanged hearing despite surgery and the rare occurrence of SNHL. Level of evidence 2c.
