Following an experimental oro-paranasal communication, the mucous membrane revealed extensive cellular reactions in the different cell layers of the nasolacrimal duct. These cellular reactions as observed histologically were mainly limited to the injured area. However, increased epithelial cell proliferation extended to other areas of the mucosal membrane as revealed by the autoradiographic observations. Fibrosis of the submucosa was a pronounced phenomenon.
The stratified columnar epithelium in an area restricted to the traumatic communication revealed pronounced metaplasia into a non keratinized squamous epithelium.
Due to the limited experimental period (6 hours–14 days) no conclusions were drawn as to the problem if the cellular reactions are reversible or not.
Acta Odontologica Scandinavica publishes original research papers as well as critical reviews relevant to the diagnosis, epidemiology, health service, prevention, aetiology, pathogenesis, pathology, physiology, microbiology, development and treatment of diseases affecting tissues of the oral cavity and associated structures including papers on cause and effect or explanatory/associative relationships for experimental or observational studies.
