Maxillary Sinus: A Niche for Endodontic Mishaps?- A Systematic Review

This systematic review was done to provide an insight into the complications and prognosis of overfilling of root canal material into the maxillary sinus. The prescribed reporting guidelines for systematic review were followed. The PEO employed for the systematic review is as follows: Population: maxillary teeth that underwent root canal treatment, Exposure: overfilling into the maxillary sinus, Outcome: complications and the associated prognosis to the event. An extensive search was done in five databases along with the grey literature to find the potentially relevant articles. After screening and selection, 18 articles were chosen for the qualitative analysis. The systematic review concluded that the foreign bodies in the maxillary sinus in the long run could result in sinusitis and infections of fungal etiology. Lack of proper knowledge and improper elucidation of history often leads to delayed diagnosis and prolonged suffering for the patients.
