Litigations faced by dentists are far more common now than what they used to be. Recent figures published by Dental Protection revealed that the willingness in the UK to sue dentists outstripped even the litigation-loving USA. The latest figures state that there are 73 claims for every 1, dentists in the UK, compared with 58 in the US.
Most deceased donors are those who have been pronounced brain dead. Brain dead means the cessation of brain function, typically after receiving an injury either traumatic or pathological to the brain, or otherwise cutting off blood circulation to the brain drowningsuffocationetc.
Breathing is maintained via artificial sourceswhich, in turn, maintains heartbeat. Once brain death has been declared the person can be considered for organ donation.
Criteria for brain death vary.
Organ donation is possible after cardiac death in some situations, primarily when the person is severely brain injured and not expected to survive without artificial breathing and mechanical support.
Independent of any decision to donate, a person's next-of-kin may decide to end artificial support. If the person is expected to expire within a short period of time after support is withdrawn, arrangements can be made to withdraw that support in an operating room to allow quick recovery of the organs after circulatory death has occurred.
Tissue may be recovered from donors who die of either brain or circulatory death. In general, tissues may be recovered from donors up to 24 hours past the cessation of heartbeat. In contrast to organs, most tissues with the exception of corneas can be preserved and stored for up to five years, meaning they can be "banked.
Because of these three factors—the ability to recover from a non-heart beating donor, the ability to bank tissue, and the number of grafts available from each donor—tissue transplants are much more common than organ transplants.
The American Association of Tissue Banks estimates that more than one million tissue transplants take place in the United States each year.
Living donor[ edit ] In living donors, the donor remains alive and donates a renewable tissue, cell, or fluid e. Regenerative medicine may one day allow for laboratory-grown organs, using person's own cells via stem cells, or healthy cells extracted from the failing organs.
Deceased donor[ edit ] Deceased donors formerly cadaveric are people who have been declared brain-dead and whose organs are kept viable by ventilators or other mechanical mechanisms until they can be excised for transplantation.
Apart from brain-stem dead donors, who have formed the majority of deceased donors for the last 20 years, there is increasing use of donation-after-circulatory-death-donors formerly non-heart-beating donors to increase the potential pool of donors as demand for transplants continues to grow.
These organs have inferior outcomes to organs from a brain-dead donor.
Allocation of organs[ edit ] See also: Organ procurement In most countries there is a shortage of suitable organs for transplantation.
Countries often have formal systems in place to manage the process of determining who is an organ donor and in what order organ recipients receive available organs. UNOS does not handle donor cornea tissue; corneal donor tissue is usually handled by various eye banks.
Individual regional organ procurement organizations OPOsall members of the OPTN, are responsible for the identification of suitable donors and collection of the donated organs. UNOS then allocates organs based on the method considered most fair by the scientific leadership in the field. The allocation methodology varies somewhat by organ, and changes periodically.
For example, liver allocation is based partially on MELD score Model of End-Stage Liver Diseasean empirical score based on lab values indicative of the sickness of the person from liver disease.
The Scientific Registry of Transplant Recipients was also established to conduct ongoing studies into the evaluation and clinical status of organ transplants. An example of "line jumping" occurred in at Duke University as doctors attempt to recover from a clear mistake.
An American teenager received a heart-lung donation with the wrong blood type for her.
She then received a second transplant even though she was then in such poor physical shape that she normally would not be considered a good candidate for a transplant.The American Student Dental Association is a national student-run organization that protects and advances the rights, interests and welfare of dental students.

Management Failures as the Basis for a Finding of Professional Misconduct - NEW by David Claxton. Dental Ethics is an ever-growing collection of resources and materials related to dental ethics, a type of ethics resource clearinghouse.
The purpose of Dental Ethics is to heighten ethical and professional responsibility, promote ethical conduct and professionalism in dentistry, advance dialogue on ethical issues, and stimulate reflection on common ethical problems in dental practice.
