The regulation of this activity goes beyond following these precepts because, in the legal relationship that is established whenever an agreement is made with a patient to carry out the treatment deemed appropriate, a series of duties and obligations begin for each party, translated into a reciprocal contract, in which the non-compliance of one of them may result in a legal claim. The objective of this study was to research most court decisions delivered in this century, in Portugal, regarding the activity of dentists when faced with patient claims and to outline a framework that better allows us to understand the regulation of this activity within the scope of the contracts established with them. This includes identifying the patients' sex, the judicial instance, the area of dentistry, the location of the injury, the type of liability, the characterization of the obligation, the basis of responsibility, the alteration of biological assets, and the outcome of the action while also not neglecting the identification of trends and jurisprudential evolutions, should they arise. A survey of judgments from the Portuguese Superior Courts was carried out, which focused on decisions from the Supreme Court of Justice, Court of Appeal of Porto, Court of Appeal of Lisbon, Court of Appeal of Coimbra, Court of Appeal of Guimarães, and Court of Appeal of Évora. To understand the judgments analyzed in this study, a brief approach to various legal concepts and institutions of interest was conducted. A summary characterization of the factual basis of the injured party's claim and the legal framework applied, as well as subsequent decisions by higher courts regarding the activity of dentists, was also elaborated. It was impossible to identify any relationship between the field of dentistry and the characterization of the obligation and the basis of responsibility, nor between the outcomes of the actions and these two parameters mentioned.

Panoramic radiographs of 800 Iranian individuals (400 males and 400 females) aged 14-23 were evaluated.

The main aim is to establish a correlation based on post-mortem (PM) dental pulp histomorphology and the PMI, and whether pulp degradation could be an available medico-legal tool for PMI estimation beyond the first week after death (late PMI). The eligible sample consisted of 27 sound teeth from 16 healthy patients aged 16 to 72 years due to orthodontic or oral surgery treatment, to create PMI's simulating the death of the subject as the time elapsed from tooth avulsion. Data collected from patients (sex, date of birth, tooth position, date and hour of the avulsion, date and hour of pulp extraction) were anonymised in accordance with the requirements of Faculty of Dental Medicine of the University of Lisbon. The sample was divided into 9 groups of 3 teeth according to different PMI sets from T0 (baseline) up to 2 weeks (T0, 7, 12, 24, 36, 48, and 72 hours, 1 and 2 weeks).

Qualitative results showed that the degeneration of dental pulp appears 7 hours after death but histological changes in vessels, fibres, and ECM in PM dental pulp are characterised by high variability, consequently it is not possible to generalise the results for early PMIs. Quantitative measurements proved that cell count cannot be standardised due to the presence of superimposed layers of cells and nuclei fragmentation.
