Data on the oral health of the elderly depict a worrying situation, with an elevated prevalence of caries and moderate periodontal disease, frequent edentulism, and numerous cases of dry mouth and oral cancer. There is wide evidence that periodontitis is a risk factor for certain systemic diseases, and impaired oral health has been associated with mastication and nutritional problems, especiall...

Edentulism, the absence of teeth, has evolved convergently among vertebrates, including birds, turtles, and several lineages of mammals. Instead of teeth, modern birds (Neornithes) use a horny beak (rhamphotheca) and a muscular gizzard to acquire and process food. We performed comparative genomic analyses representing lineages of nearly all extant bird orders and recovered shared, inactivating ...

Introduction Because of ageing and loss of teeth, alveolar bone volume has a tendency to decrease, contrary to basal bone volume which seems to have no significant modification. The practician will have, if possible, to intervene before bone anomaly installation by intercepting bone resorption. (1) Bone volume diminution in posterior maxillary alveolar ridge is a combination of several simultan...

Oromandibular dystonia with blepharospasm (also known as Brueghel's syndrome, Meige's syndrome, or idiopathic orofacial dystonia) is characterized by intense and involuntary spasms of the orofacial muscles, with a frequent loss of teeth and occlusal alterations that worsen the dystonic manifestations and cause mucosal lesions that can lead to complete edentulism. The history of a patient with o...

The dentist has a large role in geriatric health care for the ever increasing elder population with associated physical and neurological disorders. The Parkinson disease is progressive neurological disorder with resting tremor, bradykinesia, akinesia, and postural instability. The psychological components of disease include depression, anxiety, and cognitive deficiency. Poor oral hygiene, incre...

Dento-alveolar trauma and congenital absences are the most important causes of edentulism that are not associated with bacteria. However, the World Health Organization reports show that dental caries and periodontitis, two conditions of bacterial origin, are the most frequent oral diseases in humans [1]. These conditions might be avoided if an adequate oral preventive health policy is implement...
