Purpose: To assess the clinical and radiographic success rate of microsurgical endodontic treatment of upper molar teeth in relationship with the maxillary sinus, with 12 months follow-up. Methods: Patients treated with microsurgical endodontic treatment of upper molar teeth in the period between 2017 and 2019 were recruited from two dental clinics according to specific selection criteria. The outcomes were determined based on clinical and radiographic results taken three, six and 12 months post-operatively, compared with those taken immediately before and after surgery. Clinical and radiographic outcomes were recorded. The distance between the most apical part of the root and of the lesion to the maxillary sinus was measured on CBCT images before the surgery. Patient-related outcomes were recorded. Results: Out of 35 patients evaluated, 21 were selected according with the selection criteria for a total of 27 roots and 29 canals treated. After 12 months, 18 patients showed a complete healing whereas three demonstrated incomplete healing. Consequently, the success rate in this study was 85.7% after one year. In 28.5% (6 patients) there was a perforation of the Schneiderian membrane that didn’t seem to affect the outcome. All patients kept the molar one year later. The pain level decreased significantly over the time during the first week after surgery. Conclusion: Microsurgical Endodontic treatment of the upper molar teeth should be considered a valid and predictable treatment option even in case of Schneiderian membrane perforation. Future clinical studies with a larger sample size are needed to compare the results obtained.

Purpose: To investigate the prevalence of anatomic and pathologic findings in the maxillary sinus detected through cone-beam computed tomography (CBCT) in the routine of Stomatology. Materials and methods: The sample consisted of 954 CBCT scans from male (n: 330) and female (n: 624) patients aged between 2 and 86 years (mean age: 33 years). CBCT scans were taken from each patient for dental and maxillofacial diagnosis and treatment planning. The iCAT CBCT device and the inherent VisionQ software package (Imaging Science International, Hatfield, PA, USA) were used. X2 test was used to associate the anatomic and pathologic findings with patients' sex and age. Results: In both males and females, the most prevalent anatomic and pathologic findings in the maxillary sinus were, respectively, the sinus septa (21.2%) and thickening of the sinus mucosa (62.3%). Higher prevalence of maxillary sinus findings were detected within patients in the age range from 12 and 18 years (p<0.05). CBCT exams showed a high prevalence of anatomic and pathologic findings in the maxillary sinus that may have a significant clinical relevance. Conclusions: Stomatologists, Maxillofacial Surgeons and Physicians must properly interpret CBCT exams and must be aware of the occurrence of anatomic and pathologic findings prior to procedures that involve the maxillary sinus.
