RESUMO

An infectious process into the uterine cavity represents a major endangered condition that compromises the immune privilege of the maternal-fetal unit and increases the risk for preterm birth (PTB) and premature rupture of membranes (PROM). Fetal membranes are active secretors of antimicrobial peptides (AMP), which limit bacterial growth, such as Escherichia coli. Nevertheless, the antibacterial responses displayed by chorioamniotic membranes against a choriodecidual E. coli infection have been briefly studied. The objective of this research was to characterize the profile of synthesis, activity, and spatial distribution of a broad panel of AMPs produced by fetal membranes in response to E. coli choriodecidual infection. Term human chorioamniotic membranes were mounted in a two independent compartment model in which the choriodecidual region was infected with live E. coli (1 × 105 CFU/mL). Amnion and choriodecidual AMP tissue levels and TNF-α and IL-1ß secretion were measured by the enzyme-linked immunosorbent assay. The passage of bacterium through fetal membranes and their effect on structural continuity was followed for 24 h. Our results showed that E. coli infection caused a progressive mechanical disruption of the chorioamniotic membranes and an activated inflammatory environment. After the challenge, the amnion quickly (2-4 h) induced production of human beta defensins (HBD)-1, HBD-2, and LL-37. Afterwards (8-24 h), the amnion significantly produced HBD-1, HBD-2, HNP-1-3, S100A7, sPLA2, and elafin, whereas the choriodecidua induced LL-37 synthesis. Therefore, we noticed a temporal- and tissue-specific pattern regulation of the synthesis of AMPs by infected fetal membranes. However, fetal membranes were not able to contain the collagen degradation or the bacterial growth and migration despite the battery of produced AMPs, which deeply increases the risk for PTB and PROM. The mixture of recombinant HBDs at low concentrations resulted in increased bactericidal activity compared to each HBD alone in vitro, encouraging further research to study AMP combinations that may offer synergy to control drug-resistant infections in the perinatal period.

RESUMO

La erupción dental es un proceso dinámico que se inicia cuando se forma el germen dentario en su cripta de desarrollo hasta que el diente hace su aparición en boca. El folículo dental tiene un papel importante en la formación coronal y radicular del diente, y es esencial para la erupción dentaria. Para que un diente entre en erupción es necesario que exista resorción del hueso alveolar que cubre la corona del diente, de modo que se forme un camino a través del cual el diente se moverá. Para esto, se producen una serie de procesos moleculares y celulares localizados y programados genéticamente que permiten la osteogénesis y la osteoclastogénesis del hueso alveolar a fin de formar la vía de erupción. El objetivo de esta revisión es dar a conocer los posibles eventos celulares y moleculares que influyen en el proceso de erupción dentaria, ya que el mecanismo exacto aún es desconocido. (AU)


Dental eruption is a dynamic process, which begins when the dentary germ forms in the developmental crypt and finally appears in the mouth. The dental follicle has an important role in the coronal and root formation of the tooth and is essential for tooth eruption, without which the tooth could not erupt. Tooth eruption requires resorption of the alveolar bone that covers the crown of the tooth to form a path to the eruption and biological processes by which the tooth can move through this eruption path. Tooth eruption needs localized and genetically programmed molecular and cellular processes that allow osteogenesis and osteoclastogenesis of the alveolar bone to form the eruption path. The objective of this review was to describe the possible cellular and molecular events that influence the tooth eruption process, since the exact mechanism remains unknown. (AU)

RESUMO

El diagnóstico de caries dental ya no es más como el diagnóstico tradicional que mencionaba histológicamente el inicio y el final de una cavidad. Se ha demostrado que los criterios de diagnóstico y las herramientas utilizadas en la detección de lesiones de caries afectan la toma de decisiones para su tratamiento. Hoy en día, la caries dental es considerada un proceso; por ello, en el presente artículo, se describen nuevas propuestas que nos ayudarán con el diagnóstico, manejo y control de dicha enfermedad. Los criterios Cambra e Icdas son los que teóricamente tienen sustento bajo evidencia científica de lo que es actualmente la patología y su desarrollo, por lo que se describen los antecedentes históricos de su desarrollo, sus principales características, y se proponen opciones de integración al proceso diagnóstico actual a favor de una mayor conservación de la estructura dentaria. (AU)


The diagnosis of dental caries is no longer like the traditional diagnosis that histologically mentioned at the beginning and end of a cavity. It has been shown that the diagnostic criteria and tools used in the detection of caries lesions affect the decision-making process for caries treatment. Today tooth decay is considered as a process; That is why in this article new proposals are presented that will help us with the diagnosis, management and control of said disease. The criteria Cambra and Icdas, are those that theoretically have sustenance under scientific evidence of what is currently the pathology and its development; Therefore, the historical background of the development of Cambra and Icdas, its main characteristics are described, and integration options are proposed to the current diagnostic process in favor of greater preservation of the dental structure.

RESUMO

AIM: To compare in vitro the remineralizing effect of toothpastes with casein phosphopeptide-amorphous calcium phosphate (FPC-FCA) and sodium fluoride on the artificial erosion of tooth enamel. MATERIALS AND METHODS: For the first phase of artificial erosion, group I was considered as the control group without treatment or erosion. For groups II and IV, the drink was used (Coca-Cola®), for groups III and V, the drink (Inca-Kola®), and the four groups were demineralized four times a day (every 3 hours for 2 minutes) for 5 days. In the treatment phase in groups II and III, brushing was performed with sodium fluoride paste (Colgate®), groups IV and V received brushing with FPC-FCA complex (MiPaste®), and for all groups, the same procedure was performed four times a day (every 3 hours for 5 minutes) for 90 days. At the end, the microroughness of the surfaces of all the groups was evaluated by means of a Rugosimeter (Mitutoyo). RESULTS: It was evidenced that the group of sodium fluoride presented a microroughness of 2.79 µm being the group of least remineralization, but the FPC-FCA complex showed a microroughness of 1.96 µm; however, the control group presented a microroughness of 3.20 µm, and the groups sodium fluoride, FPC-FCA compared to the control group proved to be statistically significant with a p < 0.05. CONCLUSION: The remineralizing effect of FPC-FCA (MiPaste®) complex proved to be greater than sodium fluoride paste (Colgate®) under artificial enamel erosive conditions. CLINICAL IMPORTANCE: The results of this research serve as a basis for industries to generate products that have the potential for remineralization against various erosive beverages that are consumed daily.

RESUMO

Los dientes supernumerarios y las inclusiones de dientes permanentes son muy frecuentes en la infancia. Algunos dientes incluidos pueden estar asociados a la presencia de quistes dentígeros. Reportamos el caso de un paciente de sexo masculino de once años de edad con presencia de tres dientes supernumerarios en el maxilar superior, inclusión dentaria de pieza 11 e inclusión dentaria de pieza 13 con quiste dentígero asociado. El motivo de consulta fue precisamente la falta de las piezas 11 y 13 en boca. Al examen clínico intraoral presentaba: gingivitis generalizada asociada a placa bacteriana, caries dental, ausencia clínica de piezas 11 y 13, aumento de volumen en palatino a nivel de piezas 11 y 12. Al examen radiográfico se observó que las piezas ausentes en boca se encontraban incluidas y los tres dientes supernumerarios fueron hallazgos radiográficos. El tratamiento quirúrgico se realizó bajo anestesia general. El diagnóstico temprano y tratamiento multidisciplinario fueron de vital importancia.


Supernumerary and impacted permanent teeth are common in children. Some impacted teeth may be associated to dentigerous cysts. We report a case of an eleven years old male patient with presence of three supernumerary teeth in the maxilla; tooth 1.1 impacted, and 1.3 impacted associated to dentigerous cyst. The chief complaint was precisely the lack of 11 and 13 in mouth. Intraoral examination showed: generalized gingivitis associated to dental plaque, dental caries, clinical absence of 11 and 13, and increased volume on the palatal area at 12 and 11. The radiographic examination revealed that 11 and 13 were impacted, and the three supernumerary teeth were a radiographic findings. Surgical treatment was performed under general anesthesia. Early diagnosis and multidisciplinary treatment were vital.
