Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor that combines the histologic features of ameloblastoma with those of cytologic atypia. The standard treatment for this lesion is wide local excision. Proton beam therapy (PBT) can deliver high irradiation doses to the target and avoid irradiation to surrounding normal tissues, but no reports of PBT for AC have been published thus far. This report describes the case of a 70-year-old woman with a pathologic diagnosis of maxillary AC who refused surgical resection and received hypofractionated PBT at a total dose of 69 Gy in 23 fractions...

PURPOSE: In patients with oral squamous cell carcinoma (OSCC), depth of tumor invasion (DOI) is correlated with prognosis. Tumor thickness (TT) is often used as a surrogate measurement of DOI. The aim of this study was to estimate TT in a sample of patients with OSCC using ultrasound sonography (USS), magnetic resonance imaging (MRI), and clinical assessment and compare these estimates with TT of the final surgical specimen. MATERIALS AND METHODS: The authors designed and implemented a prospective cohort study and enrolled patients presenting for management of OSCC...

PURPOSE: Fractures of the condylar process are frequent. Ideal management of these fractures, as discussed in the literature, is controversial. Some recent meta-analyses have favored open reduction and internal fixation using various approaches. A strictly transoral approach has been described to minimize scarring and risk of facial nerve injury but has restricted visibility. This retrospective study analyzed outcomes of patients with unilateral mandibular condyle fractures who were treated by open reduction and internal fixation through an endoscopic-assisted transoral approach...

PURPOSE: Medication-related osteonecrosis of the jaw (MRONJ) is a rare but severe side effect of antiresorptive medications. Most animal models use tooth extraction as an instigating local factor to induce MRONJ, with varied results. However, these teeth are healthy and absent of dental disease, a rare finding that does not reflect clinical practices. The authors hypothesized that extraction of teeth with periapical inflammation would lead to MRONJ in rats treated with high-dose bisphosphonates...

PURPOSE: Osseointegrated dental implants in fibula free flaps can be used to reconstruct segmental mandibular defects resulting from head and neck resections. The double-barrel fibula flap (DBFF) has been applied as a modified method to overcome insufficient fibular width. This article describes the use of the DBFF with simultaneous dental implant placement as a superior method for esthetic mandibular reconstruction. MATERIALS AND METHODS: From 2012 to 2015, 26 patients underwent mandibular reconstruction with a free fibula flap and immediate dental implant placement after segmental mandibulectomies...

PURPOSE: The face and head play critical roles in one's sense of self and body image; as such, facial, head, and scalp injuries and potential associated disfigurement can lead to particular difficulties in coping. This study examined the psychosocial outcomes of patients with craniofacial (CF) trauma 1 year after injury and compared these outcomes with those of other traumatically injured patients who did not sustain such injuries. It was hypothesized that participants in the CF injury group would have worse outcomes than those without CF trauma...

PURPOSE: Hypoxemia and hypertension caused by obstructive sleep apnea (OSA) often result in atherosclerosis of the carotid and coronary vessels and heightened risk of stroke and myocardial infarction (MI). Therefore, this study investigated whether severity of OSA, based on the apnea-hypopnea index (AHI), is associated with the presence of calcified carotid artery (atherosclerotic) plaque (CCAP) seen on panoramic images (PIs). MATERIALS AND METHODS: Using a cross-sectional study design, the electronic medical records and PIs of all male patients referred from the sleep medicine service to the dental service from 2010 through 2016 were reviewed...

Dentofacial disharmony in patients with cerebral palsy (CP) can lead to low self-esteem and functional limitations. However, medical and behavioral challenges in patients with developmental disorders often prevent dental practitioners from offering the necessary treatment. This report describes the clinical interdisciplinary management of a 20-year-old man with CP, including orthodontic, periodontal, and orthognathic surgery therapy. The patient presented with the chief complaint of having difficulty chewing, was wheelchair dependent, had poor orofacial muscle control, and exhibited a Class III malocclusion with a skeletal anterior open bite...
