Injuries produced by animals are capable of leaving severe patterns and in some cases may result in the death of the attacked individual. Law enforcement authorities may come to erroneous conclusions about the source of the bites based on their awareness of animals present and similarities of the injuries to the untrained eye, with dreadful consequences. Expertise of a carnivore biologist and an odontologist that indentifies the particularities of bite marks may be useful for identifying the attacking species. We present the investigation of a fatal dog pack attack involving a 43-year-old man in Bell Ville (Argentina) where the evidence provided by a forensic dentist and a biologist was categorical for establishing the animal species involved. Because of the unusual characteristics of the wounds and the initial hypothesis made by local authorities of a cougar attack, habits and specific patterns of both dog pack and cougar predation on humans are discussed.

HighlightsChronological age was related to pulp chamber/crown volume ratio in a Spanish population Upper incisor ratios revealed the strongest correlation The pulp chamber/crown volume ratio explained 36.6% of the age variability The difference between chronological and dental age was <5 years in 31.3% of the sample This method of dental age estimation is gender-independent

The interaction between domestic animals and humans has not been free of conflicts, and dog attacks represent a real problem, not only for the health consequences, but also for the possible criminal, and can affect the legal or financial outcomes. Dogs' teeth have particular features, and the resulting bite marks are a major point of forensic interest mainly in the absence of witnesses or in cases where postmortem dog interference can be misinterpreted. An appropriate forensic approach should include an exhaustive analysis of the scene, the victim, and the dog. Bite marks must be discriminated from other traumas, and the familiarity of the investigator with different patterns of animal behavior can be of great importance in the correct assessment of the offending specie. A scientific inclusion/exclusion of the dog involved is possible and also recommended because of the possible consequences for the owner of the animal. Since dog bite mark analysis should involve different forensic professionals such as pathologists, odontologists, veterinarians, biologists, and also police investigators, a review focused on this type of evidence from a multidisciplinary point of view is presented. Prevention and mitigating strategies focused on both breed-specific legislation and the legal responsibility of the owner for the dog's behavior are discussed.

The fibrous epulis, a common tumor-like lesion of the gingiva, appears in the interdental papilla as a result of local irritation. Lesions are asymptomatic and have a variable growth rate. A 75-year-old woman was referred for the evaluation of a large painless gingival mass. It had started 10 years back and has been increasing in size the last year. No bone involvement was noted. The tumor was totally removed by excision with surgical scalpel under local anesthesia without teeth extraction. The microscopic findings were suggestive of a fibrous epulis. Differential diagnosis, clinical considerations and factors to prevent recurrence are discussed.

Denture marking (DM) helps identify edentulous people with different methods. Analyzing perceptions and attitudes of denture wearers would enable understanding of the practical aspects, an analysis still absent in South America. Fifty‐three individual candidates for removable dentures were instructed on disaster victim identification (DVI) and the usefulness of DM for this purpose. They were physically shown eight DM systems and a questionnaire to which they responded by highlighting preferences in those systems. Although 98.11% did not know that dentures could be marked, only 9.43% denied interest in some type of DM. The 90.57% would mark their dentures with some system, preferring the inclusion of QR codes or a micro SIM card. The proven weaknesses of DVI and propensity for disaster mean this community in Chile is an opportunity to implement DM systems. Obstacles may come not from patients but from their dentists, educational institutions, or a lack of public policies.
