RESUMEN
Background: The aim of this review was to evaluate the effects of periodontal disease (PD) treatment in pregnant women to reduce the risk of preterm birth (PB) and low birth weight (LBW) by conducting an umbrella review. Methods: A comprehensive search for the literature up to April 2024 was conducted across multiple databases including PubMed, Cochrane Library, Scopus, EMBASE, Scielo, Web of Science, Google Scholar, Proquest Dissertations and Theses, and OpenGrey. We specifically targeted systematic reviews (SRs) with or without meta-analyses, irrespective of language or time constraints, focusing on primary studies examining the effect of PD treatment in pregnant women to reduce the risk of PB and LBW. Various types of non-systematic reviews, intervention studies, observational studies, preclinical and basic research, summaries, comments, case reports, protocols, personal opinions, letters, and posters were excluded from consideration. The quality and overall confidence of the included studies were assessed using the AMSTAR-2 tool. Results: After the initial search, 232 articles were identified, of which only 24 met the selection criteria after exclusion. The majority of these studies indicated that periodontal treatment reduces the risk of PB and LBW. Conclusions: According to the findings and conclusions drawn from the SRs with a high overall confidence level, PD treatment in pregnant women reduces the risk of PB and LBW.

BACKGROUND: To compare the clinical effectiveness of ion-releasing restorations (IRR) vs. composite resin (CR) in dental restorations. METHODS: A systematic search was carried out from articles published until January 2024, in the biomedical databases: PubMed, Cochrane Library, Scielo, Scopus, Web of Science and Google Scholar. Randomized clinical trials were included, with a follow-up time greater than or equal to 1 year, without time and language limits and which reported the clinical effect of IRR compared to CR in dental restorations. The RoB 2.0 tool was used to assess the risk of bias of the included studies and the GRADEPro GDT tool was used to assess the quality of evidence and the strength of recommendation of the results. RESULTS: The search yielded a total of 1109 articles. After excluding those that did not meet the selection criteria, 29 articles remained for the quantitative synthesis. The analysis found no statistically significant difference when comparing the dental restorations with IRRs or CRs. CONCLUSION: The literature reviewed suggests that there are no differences between the IRRs and CRs in dental restorations.
RESUMEN
Objective: Determine the association between periodontal disease (PD) and obesity through an umbrella review. Materials and Methods: A search for information until March 2024 was carried out in the following electronic databases: PubMed, Cochrane library, Scopus, SciELO, Web of Science, Google Scholar, Proquest Dissertations and Theses, and OpenGrey. We included studies that were systematic reviews (SR) with or without meta-analysis, without time or language restrictions, that evaluated primary studies that associated PD with obesity. Literary or narrative reviews, rapid reviews, intervention studies, observational studies, preclinical and basic research, summaries, comments, case reports, protocols, personal opinions, letters, and posters were excluded. The AMSTAR-2 tool was used to determine the quality and overall confidence of the included studies. Results: The preliminary search yielded a total of 419 articles, discarding those that did not meet the selection criteria, leaving only 14 articles. All studies reported that PD was associated with obesity, with an OR and RR ranging from 1.1 to 1.46 and 1.64 to 2.21, respectively. Conclusions: Based on the results and conclusions of the SR with a high overall confidence level, PD is associated with obesity.

Background: To date, there is no clear consensus in the literature on which endocrown design and depth is the most effective treatment option for restoring endodontically treated maxillary central incisors. Aim: To determine the stress distribution of the anterior endocrowns by means of finite element analysis. Material and Methods: Nine 3D finite element models (groups A - I) were made, each one representing a restoration system of endodontically treated upper central incisors. The models were endocrowns with and without ferrules at 0, 1, 3, and 5 mm depth and a post-core stump control group. A static load of 100N of force was applied to the palatal face at 45º from the long axis of the tooth. The Von Mise values and the maximum stress in the crown, dentin and resin cementum were evaluated separately. Results: The maximum stress distribution was C < B < A < D < H < F < E < G < I and the Von Mises stresses were in the upper 1/3 of the retainer of endocrowns A, B, C and D. ; in the vestibular neck in endocrowns E and F; in the final 1/3 of the retainer in the endocrown G; in the middle 1/3 of the retainer in the H endocrown; and at the level of the vestibular neck of the crown in model I. Conclusions: The smallest distribution of maximum and Von Mises stresses was observed in model C.

RESUMEN
Objective: To determine, by means of a systematic review and meta-analysis, the clinical effectiveness of pre-treatment with chlorhexidine (CHX) in adhesive dental restorations. Material and Methods: A literature search was conducted until February 2020, in the biomedical databases: Pubmed, Embase, Scielo, Science Direct, Scopus, SIGLE, LILACS, Google Scholar and the Cochrane Central Registry of Clinical Trials. The selection criteria of the studies were defined, which were: randomized and controlled clinical trials, without language and time restrictions, and reporting the clinical effects (retention, marginal discoloration, marginal adaptation, postoperative sensitivity and secondary caries) of pre-CHX treatment in adhesive dental restorations. Study risk of bias was analyzed using the Cochrane Handbook of Systematic Reviews of Interventions. Results:The search strategy resulted in six articles of which five entered a meta-analysis. The studies reported that there was no difference in retention, marginal discoloration, marginal adaptation, postoperative sensitivity, and secondary caries from pre-treatment with CHX in adhesive dental restorations. Conclusion: The reviewed literature suggests that pretreatment with CHX does not influence the clinical effectiveness in adhesive dental restorations.
Resumen: Antecedentes: la pandemia de COVID-19 ha desatado un ataque sin precedentes contra la humanidad en todo el mundo. El escenario en Bangladesh empeora día a día, y todos los aspectos de la sociedad están observando su impacto. Los profesionales de la salud corren un mayor riesgo de contraer la enfermedad mientras atienden a los pacientes. Objetivo: El objetivo de la investigación es explorar el conocimiento, la conciencia y las prácticas de los dentistas registrados con respecto a la epidemiología y transmisión de COVID-19 durante el rápido brote de este virus altamente contagioso en Bangladesh. Material y Métodos: Se realizó una encuesta transversal basada en la web entre los dentistas inscritos con su número de registro único válido del Consejo Médico y Dental de Bangladesh (BMDC). Se distribuyó un cuestionario estructurado entre los dentistas a través de diferentes plataformas de redes sociales. Un total de 184 dentistas participaron en la encuesta entre marzo y abril de 2020. Se realizó tanto análisis descriptivo como análisis de regresión logística multivariable. Resultados: La edad media de los odontólogos fue de 31,75 años, con una desviación estándar de 6,5 años. Aproximadamente el 29,3% de los dentistas habían completado su título de posgrado y el 76% de ellos se dedicaba a la práctica privada en el momento de la recopilación de datos. En comparación con los dentistas con educación universitaria, los dentistas con educación de posgrado tienen tres veces (OR = 3,1, IC del 95%: 1,2 - 7,9 y más de 5 veces (OR = 5,3, IC del 95%: 1,2 - 23,3) más probabilidades de tener) mejores conocimientos y prácticas hacia COVID-19 respectivamente. Los dentistas de 26 a 30 años tienen menos probabilidades de tener buenas prácticas que los dentistas más jóvenes (OR: .1; IC del 95%: .01 - .5). Sin embargo, los dentistas con menos de cinco años de experiencia tienen 10,3 (1,6 - 68,9) veces más probabilidades de tener buenas prácticas en comparación con los dentistas con más experiencia. Conclusión: La mayoría de los dentistas de Bangladesh han demostrado un buen conocimiento, conciencia y práctica con respecto a COVID-19. Recomendamos que las autoridades sanitarias, las organizaciones profesionales y los hospitales coordinen y lleven a cabo una formación avanzada obligatoria sobre enfermedades infecciosas para todos los dentistas en ejercicio del país.
