Healing patterns after endodontic treatment for odontogenic maxillary sinusitis

Researchers have explored outcomes across patients with odontogenic maxillary sinusitis who received nonsurgical endodontic therapy.

In a case series published in the Journal of Endodontics, the researchers used cone-beam computed tomography at baseline and at up to 17 months follow-up to analyze the differential radiographic healing patterns of the maxillary sinus mucosa and periapical bone following nonsurgical root canal treatment or retreatment in a group of 10 patients with odontogenic maxillary sinusitis.

Following nonsurgical treatment, the researchers observed resolution of maxillary sinus mucosal lesions — including extensive opacification and sinus floor perforations — to normal physiologic thickness by about three months. However, periapical alveolar bone regeneration was slower, taking between three and 17 months, particularly among patients with bone destruction or periosteal displacement such as periapical osteoperiostitis (appearing as a radiopaque halo sign).

The findings highlighted the utility of early postoperative CBCT in the assessment of treatment response among more anatomically complex cases.
