Mastoid osteomas of the temporal bone are rare, benign, and usually asymptomatic tumors. However, depending on their size and extension, mastoid osteomas may cause facial palsy, a sensation of ear fullness, pressure-related pain, hearing loss, recurrent external ear infections, and chronic discharge. The etiology of mastoid osteomas is still unknown, but congenital, infectious, and traumatic factors have been proposed.

Web-based teaching has increasingly been used in medical education with a few reports also in the dental field; however, there is a lack of evidence of its full application and usefulness. The objective of this study was to evaluate the efficacy of web-based case scenarios in comparison with seminar-based training to deliver cultural competency material to the health care provider in training.

Current scientific literature supports the use of these digital systems for the detection of dental caries, periodontal bone loss, and periapical pathologies. However, relatively few studies have been published addressing the detection of dental root fractures.

Objective: The objective of this study was to compare the detection of interproximal caries in digital intraoral images presented in a 24-inch liquid crystal display (LCD) monitor and the IPad 2.
Study Design: Twenty-seven digital bitewing radiographs of 102 adult teeth were generated by a charge-coupled device sensor and presented to 4 dentists in 2 sessions. The dentists were asked to rate the presence or absence of carious lesions using a 5-point scale.
Benign and malignant tumors in the temporomandibular joint (TMJ) are rare. However, when a patient presents with clinical findings such as altered occlusion or facial asymmetry, a morphologic alteration in the condyle should be ruled out. The differential diagnosis for benign hyperplastic bony lesions in the TMJ should include condylar hyperplasia, osteochondroma, osteoma, chondroma, and osteoblastoma.

Several studies support the use of conventional two-dimensional imaging for traumas involving mainly the mandible, but for more complex situations advanced imaging modalities such as computed tomography (CT) and magnetic resonance imaging have higher indication. Nowadays, besides CT, cone-beam computed tomography (CBCT) has appeared as a reasonable and reliable alternative considering radiation dosage, image quality and comfort for the patient.

Several pathologies, including malignant diseases, may mimic temporomandibular disorders (TMD). Correct diagnosis is important to avoid treatment delay. Several new imaging diagnostic modalities are available and should be used accordingly.
