Dental trauma

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.

Prevalence

Dental trauma is most common in younger people, accounting for 17% of injuries to the body in those aged 0–6 years compared to an average of 5% across all ages. It is more frequently observed in males compared to females. Traumatic dental injuries are more common in permanent teeth compared to deciduous teeth and usually involve the front teeth of the upper jaw.

Types

Fracture

A fracture is the separation of an object or material into two or more pieces under the action of stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops perpendicular to the surface of displacement, it is called a normal tensile crack or simply a crack; if a displacement develops tangentially to the surface of displacement, it is called a shear crack, slip band, or dislocation.Fracture strength or breaking strength is the stress when a specimen fails or fractures.

The word fracture is often applied to bones of living creatures (that is, a bone fracture), or to crystals or crystalline materials, such as gemstones or metal. Sometimes, in crystalline materials, individual crystals fracture without the body actually separating into two or more pieces. Depending on the substance which is fractured, a fracture reduces strength (most substances) or inhibits transmission of light (optical crystals). A detailed understanding of how fracture occurs in materials may be assisted by the study of fracture mechanics.

Fracture (2004 film)

Fracture is a 2004 New Zealand film written and directed by Larry Parr and based on the novel by Maurice Gee. The film is set in Wellington and stars Kate Elliott, Jared Turner and Australian John Noble. The film was met with positive reviews and was the second highest grossing local film at the New Zealand box office in 2004 behind In My Father's Den.

Plot

A young solo mother (Elliott) loves her son and his needs are foremost, but she still has room in her heart for her very broken brother (Turner), even as her fundamentalist mother cruelly rejects her. But when the brother is responsible for a woman's broken neck, during his burglary of her house, families are changed as crisis amplifies and at times the young mother seems to be the only adult.

Tagline

A single crack can shatter everything.

Production

The film had originally been set for a 2003 release but was delayed during production by the dissolution of director Larry Parr's production company Kahukura Productions.

Bone fracture

A bone fracture (sometimes abbreviated FRX or Fx, F_x, or #) is a medical condition in which there is a damage in the continuity of the bone. A bone fracture can be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture.

Although broken bone and bone break are common colloquialisms for a bone fracture, break is not a formal orthopedic term.

Signs and symptoms

Although bone tissue itself contains no nociceptors, bone fracture is painful for several reasons:
