Evaluation of neodymium isotope analysis of human dental enamel as a provenance indicator using 10 Ω amplifiers (TIMS).

Human provenance studies employing isotopic analysis have become an essential tool in forensic and archaeological sciences, with multi-isotope approaches providing more specific location estimates compared to single isotope studies. This study reports on the human provenancing capability of neodymium isotopes (Nd/Nd), a relatively conservative tracer in the environment. Neodymium isotope ratios have only recently been determined on human remains due to low concentrations in human dental enamel (ppb range), requiring thermal ionisation mass spectrometry (TIMS) using 10 Ω resistors.

Articaine and neurotoxicity - a review.

The biochemical composition of articaine differs from other amide anaesthetics. The lipophilic part of articaine consists of a thiophene ring, whereas other amide anaesthetics contain a benzene ring. When used correctly, local anaesthetics are remarkably safe.

[Odontogenic pain].

A dentist is expected to be able to recognise and treat pain originating from the teeth. When dealing with short-term, acute pain, the cause can sometimes be found quickly, while this can be much harder in the case of chronic pain. Especially in this latter category, one should be even more careful in diagnostics and choose reversible treatments when possible.

Tooth autotransplantation in the anterior maxilla and mandible: retrospective results in young patients.

Objective: This retrospective study evaluated survival rates, prognosis, and overall success of autotransplanted teeth in young patients missing anterior teeth as a result of trauma, agenesis, or developmental disturbances.

Study Design: Retrospective data were collected from the medical records of patients who had undergone tooth autotransplantations to anterior sites between January 2001 and December 2012. Clinical variables, such as gender, age, surgical indications, donor and recipient sites, type of anesthetics, bone augmentation, and complications during follow-up, were assessed.

[Dental treatment under general anaesthesia in young children].

General anaesthesia in children younger than 4 years of age can cause brain damage with cognitive and behavioral problems as a result. The chance of these side effects is small, but increases with prolonged duration of the anaesthesia or when the general anaesthesia is provided more frequently. It goes without saying that the indication for anaesthesia should be very strictly set.
