Maxillary Dental Anatomy and Physiology: Endodontic and Periodontal.
Level 5 - mechanism / opinion, no new human data
Narrative review describing anatomical mechanisms without systematic methodology or primary clinical data
PubMed 39214739 · doi:10.1016/j.otc.2024.07.003
What was done
Narrative review describing the anatomy and physiology of the maxillary sinus floor, the relationship to posterior maxillary premolar and molar roots, and the microbiological pathways of endodontic infections causing apical periodontitis and odontogenic sinusitis.
What was found
The abstract reports no quantitative data or statistical comparisons. It outlines that maxillary premolar and molar roots frequently protrude into the sinus cavity separated only by a thin membrane, allowing mixed anaerobic and proteolytic biofilms in the root canal system to produce apical periodontitis and secondary odontogenic sinusitis.
Why it matters
Highlights the anatomical and microbiological mechanisms by which dental pathology causes maxillary sinus disease, aiding interdisciplinary diagnosis between otolaryngology and dental specialists.
Limits
Narrative review design with no systematic search protocol, sample size, or quantitative clinical outcomes reported in the abstract. Diagnostic accuracy and treatment efficacy metrics were not evaluated.
