Odontogenic sinusitis, a differential diagnosis: Literature review

Objective: To analyze the importance of making a good diagnosis of odontogenic sinusitis through searching in different digital databases. Methodology: A bibliography was carried out in the Pubmed and Scopus databases of studies published between 2017-2022 using keywords. In addition, the Boolean AND operator was used to connect these descriptors and the inquiries were made based on the PICO abbreviation. Results: 1270 studies were obtained from the two digital databases; from these, 50 were selected after applying exclusion and inclusion criteria. Conclusion: Odontogenic sinusitis must have a multidisciplinary diagnosis made by joint efforts on behalf of dentists and otolaryngologists. The most frequent odontogenic foci are periapical pathologies, previous surgeries, and molars that are close to the floor of the maxillary sinus. Symptoms and radiographic studies, such as CBCT, should be taken into account.
