Dental trauma – Wikipedia

Dental trauma refers to trauma (injury) to the teeth and/or periodontium (gums, periodontal ligament, alveolar bone), and nearby soft tissues such as the lips, tongue, etc. The study of dental trauma is called dental traumatology.[1]

Dental injuries[edit]

Dental injuries include:[2][3]

Periodontal injuries[edit]

Injuries to supporting bone[edit]

This injury involves the alveolar bone and may extend beyond the alveolus.[5][6] There are 5 different types of alveolar fractures:

Trauma injuries involving the alveolus can be complicated as it does not happen in isolation, very often presents along with other types of tooth tissue injuries.

Signs of dentoalveolar fracture:

  • Change to occlusion
  • Multiple teeth moving together as a segment and are normally displaced
  • Bruising of attached gingivae
  • Gingivae across the fracture line often

Fitness – Wikipedia, la enciclopedia libre

Nota: En argot científico, «fitness» también puede referirse a la aptitud biológica.

Fitness o forma física (en español buena forma) es un estado general de salud, y en forma más específica se le llama a la capacidad de practicar ciertas actividad físicas, ocupaciones y actividades cotidianas. Una buena forma física por lo general se adquiere como resultado de una nutrición adecuada,[1]​ la práctica de ejercicio físico de moderados a vigorosos,[2]​ y un descanso apropiado.[3]

Con anterioridad a la revolución industrial, se definía forma física como la capacidad de realizar las actividades cotidianas sin experimentar fatiga. Sin embargo, con la automatización y los cambios en el estilo de vida en la actualidad se considera que la forma física es una medida de la capacidad del cuerpo de funcionar de forma eficiente y efectiva durante el trabajo y actividades

Expected reproductive success

Fitness (often denoted

w{displaystyle w}

or ω in population genetics models) is the quantitative representation of natural and sexual selection within evolutionary biology. It can be defined either with respect to a genotype or to a phenotype in a given environment. In either case, it describes individual reproductive success and is equal to the average contribution to the gene pool of the next generation that is made by individuals of the specified genotype or phenotype. The fitness of a genotype is manifested through its phenotype, which is also affected by the developmental environment. The fitness of a given phenotype can also be different in different selective environments.

With asexual reproduction, it is sufficient to assign fitnesses to genotypes. With sexual reproduction, genotypes are scrambled every generation. In this case, fitness values can be assigned to alleles by averaging over possible genetic backgrounds. Natural selection tends to

Il personal trainer (anche detto allenatore personale e convenzionalmente indicato dalla sigla PT) è la figura professionale preposta a gestire in maniera individualizzata l’esercizio fisico di coloro che si avvicinano o praticano attività fisica per migliorare il proprio stato di salute o di forma fisica.

Un’altra importante area di intervento del personal trainer è relativa all’educazione a stili di vita salutari e al ruolo di motivatore nell’ambito della pratica dell’attività fisica.

Il background culturale di un personal trainer è di tipo interdisciplinare, in continua formazione ed aggiornamento, passa attraverso la fisiologia, l’anatomia funzionale, la psicologia, la medicina dello sport, l’allenamento e la nutrizione.

Health care, health-care, or healthcare is the maintenance or improvement of health via the prevention, diagnosis, treatment, recovery, or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals in allied health fields. Physicians and physician associates are a part of these health professionals. Dentistry, pharmacy, midwifery, nursing, medicine, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training and other health professions are all part of health care. It includes work done in providing primary care, secondary care, and tertiary care, as well as in public health.

Access to health care may vary across countries, communities, and individuals, influenced by social and economic conditions as well as

Medicine is the science and practice of establishing the diagnosis, prognosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Medicine has been around for thousands of years, during most of which it was an art (an area of skill and knowledge) frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism. In recent centuries, since the advent of

En tiempos de antaño[¿cuál?], el obispo estaba encargado de cuidar de todos los pobres, leprosos y enfermos, de las viudas, huérfanos y peregrinos, y cuando las iglesias tenían rentas seguras, se destina la cuarta parte de ellas al socorro de los pobres. Esta separación dio lugar al establecimiento de hospitales, domus religiosæ

Biomedicine – Wikipedia

Branch of medical science that applies biological and physiological principles to clinical practice

Biomedicine (also referred to as Western medicine, mainstream medicine or conventional medicine)[1] is a branch of medical science that applies biological and physiological principles to clinical practice. Biomedicine stresses standardized, evidence-based treatment validated through biological research, with treatment administered via formally trained doctors, nurses, and other such licensed practitioners. [2]

Biomedicine also can relate to many other categories in health and biological related fields. It has been the dominant system of medicine in the Western world for more than a century.[3][4][5][6]

It includes many biomedical disciplines and areas of specialty that typically contain the “bio-” prefix such as molecular biology, biochemistry, biotechnology, cell biology, embryology, nanobiotechnology, biological engineering, laboratory medical biology, cytogenetics, genetics, gene therapy, bioinformatics, biostatistics, systems biology, neuroscience, microbiology, virology, immunology, parasitology, physiology, pathology, anatomy, toxicology, and many

Health (band) – Wikipedia

Health (often stylized as HEALTH) is an American noise rock band from Los Angeles, California.

History[edit]

Health was created after its members agreed the name should be an “everyday word.” After reviewing a long list of terms, “health” was the only one not taken.[6]

Health[edit]

Health first gained reputation through a remix of their song “Crimewave” by experimental electronic band Crystal Castles in August 2007. The rendition helped broaden Health’s audience in anticipation for their full-length debut a month later released under LovePump United. The band’s self-titled album was recorded in L.A.’s noise/experimental venue, The Smell. Known for its DIY mystique, Health knew how difficult, yet rewarding, it would be to record in the space. Famiglietti said in an interview, “The room completely changes the tone of anything you want to record; makes a lot of things dark and beautiful. It also

Dentistry is a specialty in medicine, which is practiced by a dentist. Dentists find out what’s wrong, fix, and help prevent problems with teeth. A dentist has other people that help him with their job. Dental hygienists help people keep their teeth clean. A dental assistant helps the dentist when they are treating a patient. Dental surgeons will perform surgery to fix large or dangerous problems with people’s teeth. There are also dentists called orthodontists, who can move people’s teeth using braces. Dental surgeons and orthodontists are called specialists.[1]
