In recent years, forensic dentistry reaches critical importance worldwide, getting through certain procedures to estimate, time and date of death of a person, facilitating the resolution of multiple and complicated cases of death. The procedures employed also allow the lifting of fingerprints by applying techniques; Queiloscopía, Biting, Registration Rugas Palatine, providing thus a great contribution in the Criminal Investigation in its first phase Inquest, within which the processing of the scene seeks to collect evidence and binding evidence the fact that subsequently through a chain of custody is transferred to the laboratory where the evidence and evidence will be studied, becoming media expert evidence to identify the fact and authorship of an allegedly criminal act, thus presents a collection of literature concerning the subject that seeks to inform the general practice dentist o...

In Ecuador, there is a high prevalence and incidence of different oral pathologies, this scenario is similar in several countries in the region. Oral diseases constitute a Public Health issue, since they involve a high investment in their management and control. Thus, an emphasis in preventive activities has been placed to improve the impact of oral diseases. Several measures have been taken by the Ecuadorian government to reduce the incidence of dental caries, including massive prevention programmes. For instance, fluoridation of food and water, school teaching of right tooth brushing techniques and dental floss use, early detection of bacterial plaque, delivery of educational talks, and sealant placement on occlusal surfaces of permanent teeth in schoolchildren from deprived urban and rural populations. Nevertheless, these strategies have not been monitored, evaluated or reported in or...

En los últimos años la odontología forense alcanza a nivel mundial fundamental importancia, consiguiendo, mediante determinados procedimientos, estimar hora y fecha de muerte de una persona, facilitando la resolución de múltiples y complicados casos de muerte. Los procedimientos empleados también permiten el levantamiento de huellas aplicando técnicas para queiloscopía, mordidas, registro de rugas palatinas, brindando de esta forma un gran aporte en la investigación criminal en su primera fase indagatoria, dentro de la cual el procesamiento de la escena busca colectar indicios y evidencias vinculantes al hecho, que posteriormente a través de una cadena de custodia se trasladarán al laboratorio donde los indicios y evidencias serán estudiados, pasando a ser medios de prueba pericial para poder identificar el hecho y la autoria de un acto presuntamente criminal.

Introduction: The premature loss of one or more primary teeth in children under 10 years of age, mainly due to dental trauma or a cariogenic process, causes a reduction of space for definitive teeth; in this case, it is essential to use space maintainers depending on each specific case, since the choice of an adequate method would prevent later problems arising from the loss of space as well as from inadequate use of these devices. Objective: To analyze the use of fixed retainers in the absence of primary molars in patients under 10 years of age. Materials and methods: A descriptive review of the literature was carried out using search strategies in the PubMed database published between 2017 and 2022. Results: Through the strategies used, 53 articles were found, from which those that did not contain com­parisons between space maintainers and cementation failures were removed, leaving 14...

Objectives. Tooth decay, due to their multifactorial etiology, spark constant interest in finding new methods for controlling the causal factors of this illness. Some of the major causes are Streptococcus mutans and Streptococcus sanguis. Therefore, it was proposed to determine the effectiveness in vitro of myrtle obtained through a watery and oily process on Streptococcus mutans and Streptococcussanguis strains. Materials and methods. The minimal bactericidal concentration for each extract was determined, and the bactericidal activity through a inhibition halo count, using 0,12% chlorhexidine as a positive control and distilled water as a negative control. The microbiological tests were executed following parameters previously validated by persons trained in performing them.The results obtained were analyzed through the ANOVA test, which estimated a significance of p=0, Se encontró qu...
