Introduction and objective:

The aim of this review is to evaluate to what extent sinus pathology originates from dental pathology or treatment, and to assess the occurrence frequency of sinus pathology in its different forms using cone beam computed tomography (CBCT).

Method:

The literature review was conducted using PubMed, Scopus and the Cochrane Library. Forty-two articles were included (25 case series, ten cross- sectional studies, three case-control studies, two cohort studies, one prospective study, and one retrospective study).

Results:

Forty-two articles involving a total of 13,191 patients and 17,374 CBCTs were included in this review. The most frequent pathological findings were, by a considerable degree, inflammatory diseases, which represented 75.16 % of the total findings, followed by infection (12.13 %), tumours (6.88 %), and high pneumatisation (2.07 %). Within dental pathology, there is a direct Pearson correlation with polyps (1) and opacification (0.999), and an almost direct correlation with retention cysts (0.981) and sinus-associated dental elements (0.972).

Conclusions:

Our results further support the argument that dental modifications and treatments are an important cause of sinus pathology. For this reason, dental aetiologies must be taken into account by both dentists, maxillofacial surgeons and ENT when considering the most appropriate treatment for patients with maxillary sinusitis.
