Altered mastication adversely impacts morpho-functional features of the hippocampus: A systematic review on animal studies in three different experimental conditions involving the masticatory function.

Recent results have established that masticatory function plays a role not only in the balance of the stomatognathic system and in the central motor control, but also in the trophism of the hippocampus and in the cognitive activity. These implications have been shown in clinical studies and in animal researches as well, by means of histological, biochemical and behavioural techniques. This systematic review describes the effects of three forms of experimentally altered mastication, namely soft-diet feeding, molar extraction and bite-raising, on the trophism and function of the hippocampus in animal models.

Temporomandibular Disorders and Oral Features in Systemic Lupus Erythematosus Patients: An Observational Study of Symptoms and Signs.

: Systemic Lupus Erythematosus (SLE) is a connective tissue disease characterized by a wide range of pleomorphic pictures, including mucocutaneous, renal, musculoskeletal and neurological symptoms. It involves oral tissues, with hyposalivation, tooth decay, gingivitis, angular cheilitis, ulcers and glossitis. Temporomandibular disorders represent a heterogeneous group of inflammatory or degenerative diseases of the stomatognatic system, with algic and/or dysfunctional clinical features involving temporomandibular joint (TMJ) and related masticatory muscles.

Chapter 14: Impact of Oral Health on Diet/Nutrition.

An individual's oral health status has a profound impact on his/her acquisition and utilization of nutrients and interchangeably the nutrients an individual consumes determine the state of oral health by preventing tooth loss and oral diseases. Oral diseases have a considerable impact on the masticatory function which is a critical first step in oral processing of food materials for nutrient procurement. Specifically, a section of this chapter is dedicated to the physiology of masticatory function and to the recent acknowledgement of its influence on memory and cognition, both during development and aging.

Paediatric Orthodontics Part 3: Masticatory function during development.

The importance of masticatory function during development, the aim of early therapies. Hypoplasia of the upper maxilla is a widespread condition which orthodontists often need to face during early treatment. Mechanical maxillary expansion (both rapid and slow) produce undiagnosed effects on the palatal suture and unwanted side- effects on the periodontium and alveolar process, as well as anchorage-teeth displacement, root resorption, bone fenestration.
