Paraformaldehyde has been used in the past as a pulpotomy agent. However, it has a severe cytotoxic effect and may cause alveolar bone necrosis. Depulpin, a devitalizing agent containing 49% paraformaldehyde, is no longer used frequently due to its severe side effects. In the two cases described in the present study, Depulpin was used as a devitalizing agent during root canal treatment. It caused a gradual loss of sensibility in adjacent teeth, gingival necrosis, and osteomyelitis. This case report demonstrates the serious side effects of using a paraformaldehyde-containing paste as a devitalizing agent for pulp, particularly mandibular bone necrosis.

Pyogenic vertebral osteomyelitis is rare. It most commonly occurs at the lumbar area and in the fifth to seventh decades of life. Most individuals present with back pain, abdominal pain, hip pain and meningeal syndrome. We experienced three cases of unusual patterns of pyogenic osteomyelitis. The first case developed after sepsis. The second case developed after open fracture and infection of other site. The third case was misdiagnosed as metastatic cancer. We present these cases with a brief review of literatures.

A 22-year-old male patient had developed a submasseteric abscess secondary to a mandibular osteomyelitis at the age of 7 years old. The initial presentation at that time seems to be acute suppurative parotitis. The computed tomographic scans taken before surgery demonstrated diffuse deformity, sclerotic change and osteolytic lesion in the mandible. There was no marrow space on both sides of mandibular ramus and thin-walled cortical bone was seen. So, from the results of the computed tomography, the surgery was performed intraoral vertical ramus osteotomy (IVRO) instead of performing the more commonly used bilateral sagittal split ramus osteotomy (BSSRO). In this report, we present a case of surgical correction of mandibular prognathism with fibrous-osseous lesion of mandible with using IVRO.

Proliferative periostitis is a rare form of osteomyelitis that is characterized by new bone formation with periosteal reaction common causes of proliferative periostitis are dental caries, periodontitis, cysts, and trauma. While proliferative periostitis typically presents as a localized lesion, in this study, we describe an extensive form of proliferative periostitis involving the whole mandibular ramus and condyle. Because the radiographic findings were similar to osteogenic sarcoma, an accurate differential diagnosis was important for proper treatment.

Retropharyngeal abscesses are uncommon but potentially lethal infections, especially in the pediatric population. In adults, retropharyngeal abscesses are very rare and usually secondary to chronic tuberculous cervical spine osteomyelitis. Retropharyngeal tuberculosis can manifest itself as a cold abscess, and the symptoms and signs are usually influenced by its size and location. We present two cases of retropharyngeal abscess in adults without tuberculous cervical osteomyelitis.

Chronic invasive fungal sinusitis (CIFS) is a relatively rare disease which occurs in immunocompetent or immunocompromised patients. We report a case of CIFS in ethmoid sinus with concurrent fungal ball in maxillary sinus. After surgical debridement and antifungal therapy, CIFS recurred with submucosal invasion in nasopharynx and osteomyelitis of clivus. Although CIFS encompasses a slowly progressing invasive fungal disease but potentially aggressive. It should be noted that CIFS could progress and extend through submucosal route without evidence of mucosal lesion.

Necrotizing fasciitis (NF) is a rapidly progressive necrosis of the subcutaneous tissue and fascia, caused by bacterial infection. Usually presenting in the extremities, trunk, or perineum, it is uncommon in the craniofacial or cervical area. Cervicofacial NF is a potentially fatal infection, which should be managed with early detection and intervention. Most cases have a primary odontogenic source of infection, especially when the masticator space is involved. We report a case of masticator space NF that developed without odontogenic origin in a 78-year old female who was treated with prompt surgical drainage and intravenous antibiotics.

This review presents an overview of some diagnostic imaging-related issues regarding medication-related osteonecrosis of the jaws(MRONJ), including imaging signs that can predict MRONJ in patients taking antiresorptive drugs, the early imaging features of MRONJ, the relationship between the presence or absence of bone exposure and imaging features, and differences in imaging features by stage, between advanced MRONJ and conventional osteomyelitis, between oncologic and osteoporotic patients with MRONJ, and depending on the type of medication, method of administration, and duration of medication. The early diagnosis of MRONJ can be made by the presence of subtle imaging changes such as thickening of the lamina dura or cortical bone, not by the presence of bone exposure. Most of the imaging features are relatively non-specific, and each patient's clinical findings and history should be referenced. Oral and maxillofacial radiologists and dentists should closely monitor plain radiographs of patients taking antiresorptive/antiangiogenic drugs.
