Wegener's granulomatosis (GW) is a multisystemic granulomatous vasculitis that predominantly affects the airways and the kidneys, but may affect any organ. Otorhinolaryngological manifestations may be gingival swelling, oral ulcer or septal perforations that can cause saddle nose deformities, rhinitis, sinusitis and hearing loss. We report a case of WG that was first diagnosed on oral gingival mucosa. A 54-year old woman was referred to a specialized dentist because of consistent irritative buccal gingival hyperplasia that did not react to conservative and microbial treatment...

Osteoporosis affects all bones, including those of the facial skeleton. To date the facial bones have not drawn much attention due to the minimal probability of morbid fractures. Hearing and dentition loss due to osteoporosis has been reported. New research findings suggest that radiologic examination of the facial skeleton can be a cost-effective adjunct to complement the early diagnosis and the follow up of osteoporosis patients. Bone-mass preservation treatments have been associated with osteomyelitis of the jawbones, a condition commonly described as osteonecrosis of the jaws (ONJ)...

The SoundBite hearing system (Sonitus Medical, San Mateo, Calif) allows people with single-sided deafness to wear an intraoral device and a small microphone in the deaf ear to regain lost hearing. A piezoelectric activator in a small removable unilateral oral appliance conducts sound through the bone via the teeth to the good ear. The goal of this article is to introduce the SoundBite, a new bone-conduction hearing device, to dentists and orthodontists.

BACKGROUND: Rotating instruments in dentistry are radiating an unpleasant high-frequency noise, which was supposed to produce hearing loss by its loudness. Therefore frequently notifications and recognizing procedures were initiated because of the suspicion of occupational noise-induced hearing loss (German listing for occupational diseases as given by decree: Number 2301). In recent years dentists, dental technicians and dental assistants repeatedly had to be tested because of a suspicion for noise-induced inner ear damage...
