Potential Impact of Prosthetic Biomaterials on the Periodontium: A Comprehensive Review.
Romero Castro, Norma Samanta
The success of a prosthetic treatment is closely related to the periodontal health of the individual. The aim of this article was to review and present the importance of prosthetic restorative materials on the condition of the periodontium, the changes that occur in the composition of the subgingival microbiota and the levels of inflammatory markers in gingival crevicular fluid. Articles on the influence of different prosthetic restorative materials on subgingival microbiota and proinflammatory cytokines were searched for using the keywords ¿prosthetic biomaterials¿, ¿fixed prosthesis¿, ¿periodontal health¿, ¿subgingival microbiota¿, ¿periodontal biomarkers¿ and ¿gingival crevicular fluid¿ in PubMed/Medline, Science Direct, Scopus and Google Scholar. The type of material used for prosthesis fabrication together with poor marginal and internal fit can result in changes in the composition of the subgingival microbiota, as well as increased accumulation and retention of dentobacterial plaque, thus favoring the development of periodontal disease and prosthetic treatment failure. Biological markers have helped to understand the inflammatory response of different prosthetic materials on periodontal tissues with the main purpose of improving their clinical application in patients who need them. Metal-free ceramic prostheses induce a lower inflammatory response regardless of the fabrication method; however, the use of CAD/CAM systems is recommended for their fabrication. In addition, it is presumed that metal-ceramic prostheses cause changes in the composition of the subgingival microbiota producing a more dysbiotic biofilm with a higher prevalence of periodontopathogenic bacteria, which may further favor periodontal deterioration.

Analysis of subgingival microbiota and IL-1¿, TNF-¿ and CX3CL1 levels in gingival crevicular fluid of fixed dental prostheses.
Romero Castro, Norma Samanta
Prosthetic biomaterials can affect the composition of the subgingival microbiota and consequently the production of proinflammatory cytokines, causing damage to the periodontium. A total of 40 patients were divided into two groups: 20 with monolithic zirconia (MZ) prostheses and 20 with porcelain fused to metal (PFM) with nickel-chromium (Ni-Cr) alloy prostheses. Subgingival plaque and gingival crevicular fluid samples were taken. The Checkerboard technique for DNA-DNA hybridization and the enzyme-linked immunosorbent assay technique were performed. Teeth with MZ presented a lower percentage of bleeding on probing and tooth mobility compared to teeth with PFM with Ni-Cr alloy. Prosthodontic teeth harbored higher total levels of the 18 bacterial species than non-prosthodontic teeth. There was a higher prevalence of S. gordonii and V. parvula species in PFM with Ni-Cr alloy compared to MZ. There was an increase in IL-1¿, TNF-¿ and CX3CL1 levels in PFM with Ni-Cr alloy compared to MZ. MZ is a candidate biomaterial with fewer negative effects on the periodontium, allowing for longer prostheses longevity in the mouth.

El poder en la arquitectura religiosa de Taxco, Gro.
Alcaraz Morales, Osbelia; Salgado Galarza, Agustin Carlos
The purpose of this work is to analyze what religious architecture expresses, this start with the idea that a whole city and its architecture shows how it is organized socially. The architecture and the Mexican colonial cities, were founded with the intention of achieving the ideological domain of the Spanish Crown, with the same purpose the Catholic religion was introduced into the imaginary of Mexicans. Religion has played a fundamental role in the ideological domination exercised by the hegemonic class over the subaltern mass, for which religious architecture is necessary, they are the spaces where the doctrine of the believer is exercised. The religious temples were built, based on the interests and imaginaries of the ruling class. This architecture represents the interests of the class that it has the economic and ideological power, over the rest of society. In this paper, it was studied the origin and power of religious architecture in Mexico, as a way of studying the chapels and the parishes of Santa Prisca and San Sebastian of the city of Taxco de Alarcon, Guerrero in Mexico are analyzed.

La vivienda de segunda residencia y su impacto en los hoteles de Acapulco, Guerrero.
Alcaraz Morales, Osbelia
La vivienda de segunda residencia es un modelo habitacional que se presenta en forma masiva, principalmente en destinos turísticos de sol y playa, como el puerto de Acapulco, Guerrero. Este fenómeno se manifiesta en el mercado inmobiliario de manera desbordada, con efectos nocivos para la estructura urbana a causa de la mala planeación, que no se esmera por brindar el confort óptimo a sus habitantes. Además existe una especie de competencia desleal con los hoteles, ya que el surgimiento de este nuevo estilo de hospedaje ocasiona que algunos edificios de alojamiento cambien defunción al ser adaptados como departamentos; de esta forma surge un mercado inmobiliario en expansión de vivienda de segunda
residencia.
