Pyknodysostosis is a rare, recessive, hereditary, autosomal disease belonging to the group of bone dysplasias. Complications such as osteomyelitis and fractures of the mandible are not uncommon and appear in the most varied forms. We report a case of chronic osteomyelitis with subsequent mandible fracture, which was successfully treated with the use of a reconstruction plate and antibiotic therapy. This article outlines the clinical and radiographic characteristics of this condition based on the clinical case described and proposes an approach regarding the best form of treatment. Considering the risks of fracture subsequent to removal of the graft from long bones as well as the presence of chronic infection, difficult-to-defeat infection, and bone contact on the compression band, the best choice is a more conservative treatment.

Sialolithiasis is a benign pathology that occurs most frequently in the submandibular salivary gland due to its anatomic features. Depending on the size and degree of calcification, a sialolith can be visible in radiographic examinations. Patients commonly experience pain and/or edema when the ducts are obstructed. The authors report two cases of sialolithiasis of the submandibular gland after searching for the source of swelling in the submandibular region. The diagnosis was confirmed by clinical and tomographic examinations. Despite the considerable size of the sialoliths, treatment consisted of the removal of the calcified mass using an intraoral surgical approach. The prognosis is often good and there is generally no recurrence of the condition.
