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...

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. Se presenta asÃ...

 A esthetic and functional rehabilitation is considered the maximum objective of any dental treatment, with a sustained and updated scientific base, always seeking a complete and comprehensive diagnosis, focused on presenting a treatment plan according to comprehensive needs of the patient, executed in a conscious way with an established multidisciplinary approach, with foundations based on constant dialogue between the professional, the patient and the dental technician. The objective of this report is to describe step by step the clinical stages of a multidisciplinary treatment which is based on prior diagnosis and planning; looking for the interaction of different specialties: periodontics, oral rehabilitation, aesthetic dentistry, occlusion, and an integral work with the dental laboratory, to achieve the stability of periodontal and dental tissues. Thus recovering the masticatory fu...

Objectives: An in vitro study which was assessed by testing the appropriate microfiltration protocol using a conventional ionomer cement with sandwich technique in Black’s cavities class I. Methods: 60 human premolars, which underwent standardized cavities. These were randomly divided into 4 groups of 15 teeth each: G1 had IVC Ketac Molar Easymix and G3 had Ionofil Plus respectively to the edge of the cavity and then to wear them in 24 hours, leaving 1mm cavity base and subsequently using phosphoric acid on both enamel and dentin. In G2 and G4 both were simultaneously conditioned with polyacrylic on dentin and phosphoric acid on enamel, followed by washing, drying and 1mm placement of IVC Ionofil Plus and Ketac Molar Easymix respectively. All groups received two layers of adhesive OneCoat S Bond Coltene, light cured for 30 seconds, finally Brillant Coltene resin was applied in an incre...

Objectives: Our aim was to determine the prevalence of fluorosis among the population of children who live in Tumbaco Valley, Quito, Ecuador. We sought to establish its relation to the concentration of fluoride in the water supply of this área. Material and methods: The sample was 62 children who were selected based upon previously defined inclusion and exclusion criteria. All of the children were clinically examined; a photographic record of upper anterior teeth surfaces was performed. Results: The analyzed data showed that only 23,3% of the children surveyed had rates of dental fluorosis, with TF-2 being the most common. Chemical analysis of water from the supply source showed the presence of fluoride in very small amounts which did not exceed 0,32 mg/L. Conclusions: The low presence of fluoride in the examined water sources explains the absence of fluorosis in the assessed population...

Objective: To assess the action of two types of fluorides over dental enamel surface. Materials and methods: Extracted molars were randomly divided into 8 groups, comprising 7 experimental groups and one control group. Each molars from the experimental groups was treated in a sterile small container with artificial saliva and lactic acid for 48 hours. Saliva was changed and the teeth were put in contact with gel and varnish fluoride at different periods of time (2, 24, 26, 50, 52 hours). The molars from the control group receive no treatment. Data from measurements of pH and calcium absorption (CCa) were collected from the artificial saliva of each group at different periods of time, in contact with lactic acid and with both fluorides, weight was also measured. This data was analyzed through ANOVA (p < 0, 05) and the Tukey test. Results: The contact with lactic acid produced a great l...
