Study links impacted canines with maxillary sinus anatomy

Version 1 — Brief

A new systematic review and meta-analysis in The Angle Orthodontist examined whether patients with impacted maxillary canines have different maxillary sinus volume and dimensions than patients without impaction. Based on the study abstract, the authors searched five databases through August 2025 and included cone-beam computed tomography studies comparing sinus volume and linear dimensions in these groups. The paper adds to a small but growing imaging literature suggesting that impacted canines are associated with measurable anatomic differences in the maxillary sinus region, an area that matters for diagnosis and treatment planning. Earlier CBCT studies have reported reduced sinus volume on the impacted side and other maxillofacial differences in patients with impacted canines. (angle-orthodontist.kglmeridian.com)

Why it matters: For veterinary dental and oral surgery teams, the paper is a reminder that impacted teeth can be tied to broader regional anatomic changes, not just local eruption problems. While this review is in human orthodontic patients, the clinical takeaway is familiar across species: advanced imaging can clarify the relationship between impacted teeth and nearby structures, support risk assessment, and shape decisions about monitoring, surgical exposure, extraction, or orthodontic management where available. Impacted canines are also clinically important because untreated cases can be associated with root resorption, cyst formation, infection, pain, and prolonged treatment complexity.

What to watch: Watch for the full paper’s pooled effect estimates, heterogeneity, and evidence-certainty ratings, which will determine how much this review should change imaging and treatment protocols. (link.springer.com)
