RESUMEN

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

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.

RESUMEN

Abstract The present research aims to determine the antimicrobial efficacy of the mouthwashes based on cetylpyridinium chloride (CPC), before aerosol producing dental procedures. A data search was performed during August 2021 in five databases MEDLINE (PubMed), SCOPUS, SCIELO, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar. Randomized clinical trials (RCTs) were included based on the PICO question, comparing the efficacy of the mouthwashes based on cetylpyridinium chloride (CPC), versus other mouthwashes and water, before aerosol producing dental procedures, papers in English, Spanish and Portuguese were included without time limits. The risk of the included studies was evaluated with the tool RoB 2.0. Number of registration PROSPERO N° CRD42021275982. 120 papers were obtained in the preliminary search, discarding those that didn't comply with the selection criteria, leaving only 3 studies. These papers reported the use of cetylpyridinium chloride (CPC) was effective for the reduction of bacteria during the ultrasonic prophylactic procedure. The use of CPC mouthwashes previous to the dental treatment with ultrasonic prophylaxis showed only antibacterial capacity.

RESUMEN

BACKGROUND: The purpose of this review is to determine the association between the risk of preterm birth and low birth weight in newborns and periodontal disease in pregnant women. METHODS: A bibliographic search was carried out until November 2021 in the following biomedical databases: PubMed/Medline, Cochrane Library, Scopus, EMBASE, Web of Science, Scielo, LILACS and Google Scholar. Studies reporting the association between the risk of preterm birth and low birth weight in newborns with periodontal disease in pregnant women, which were systematic reviews, in English and without time limits were included. AMSTAR-2 was used to assess the risk of the included studies, and the GRADEPro GDT tool was used to assess the quality of the evidence and the strength of the recommendation of the results. RESULTS: The preliminary search yielded a total of 161 articles, discarding those that did not meet the selection criteria, leaving only 15 articles. Seven articles were entered into a meta-analysis, and it was found that there is an association between the risk of preterm birth and low birth weight in newborns with periodontal disease in pregnant women. CONCLUSIONS: There is an association between the risk of preterm birth and low birth weight in newborns with periodontal disease in pregnant women.

RESUMEN

Background: Temporomandibular disorders (TMD) are related to a series of clinical manifestations that appear in the form of pain. Currently, there is controversy about the appearance of TMDs after orthodontic treatment. Therefore, the objective of the present study was to determine the association between orthodontic treatment and the occurrence of Temporomandibular Disorders (TMD). Material and Methods: A bibliographic search was carried out until April 2022, in the following electronic databases: Pubmed/Medline, Scopus, Scielo, Google Scholar and Web of Science. We included studies that were case-control and cohort studies, dealing with the association between orthodontic treatment and TMD, in English and Spanish, and with no time limit. The Newcastle-Ottawa scale was used to assess risk in the included studies. In addition, RevMan 5.3 was considered for meta-analysis, using as a measure the ODDS ratio in a random-effects model with a 95% confidence interval. Results: The preliminary search yielded a total of 686 articles, discarding those that did not meet the selection criteria, leaving only 6 articles. These studies reported that there is a significant association between orthodontic treatment and the occurrence of TMD, equivalent to an ODDS ratio of 1.84 with a confidence interval of 1.19-2.83. Conclusions: It is concluded that there is an association between orthodontic treatment and the occurrence of TMD, therefore, a person undergoing orthodontic treatment is up to 1.84 times more likely to develop TMD. Key words:Orthodontic treatment, temporomandibular disorders, orthodontics, cases and controls, cohorts, review, Meta-Analysis.

RESUMEN

The objective of this systematic review and meta-analysis was to determine the clinical effectiveness of bulk-fill and conventional resin in composite restorations. A bibliographic search was carried out until May 2020, in the biomedical databases Pubmed/MEDLINE, EMBASE, Scopus, CENTRAL and Web of Science. The study selection criteria were: randomized clinical trials, in English, with no time limit, with a follow-up greater than or equal to 6 months and that reported the clinical effects (absence of fractures, absence of discoloration or marginal staining, adequate adaptation marginal, absence of post-operative sensitivity, absence of secondary caries, adequate color stability and translucency, proper surface texture, proper anatomical form, adequate tooth integrity without wear, adequate restoration integrity, proper occlusion, absence of inflammation and adequate point of contact) of restorations made with conventional and bulk resins. The risk of bias of the study was analyzed using the Cochrane Manual of Systematic Reviews of Interventions. Sixteen articles were eligible and included in the study. The results indicated that there is no difference between restorations with conventional and bulk resins for the type of restoration, type of tooth restored and restoration technique used. However, further properly designed clinical studies are required in order to reach a better conclusion.

RESUMEN

El objetivo del presente estudio fue determinar y comparar la efectividad de la Benzocaína en gel al 20% y la Lidocaína en solución al 10% en pacientes que requerían punción en la mucosa oral. El presente es un ensayo clínico controlado aleatorizado a triple ciego y de diseño cross-over. Se llevó a cabo en la clínica dental de la Unidad de Segunda Especialización en Estomatología (USEE) de la Universidad Nacional de Trujillo, durante los meses de Noviembre y Diciembre del 2010 y de Enero a Marzo del 2011. La muestra estuvo conformada por 60 pacientes, cada paciente firmó un consentimiento informado y se le realizó un análisis de su estado de ansiedad mediante la escala de ansiedad estado-rasgo (IDARE). Antes de realizar la punción en la mucosa oral se aplicó 4 preparados (2 anestésicos tópicos y 2 placebos) para después determinar y comparar la efectividad de los preparados en la reducción del dolor usando la escala visual análoga (EVA). Para la recolección de los datos se usó una ficha especial para tal fin. Para la comparación de la efectividad de los preparados se empleó el Análisis de Varianza (ANOVA). La efectividad de los anestésicos en gel y en solución fue evaluada empleando el test de Tuckey para comparaciones múltiples y el T de students. La significación estadística fue del 5%. Se encontró que la Benzocaína en gel al 20% y la Lidocaína en solución al 10% son efectivos para reducir el dolor a la punción y que no existe una relación estadísticamente significativa (p= 0,0575) entre la efectividad de cada uno de ellos. La administración de Benzocaína en gel al 20% o de la Lidocaína en solución al 10% reduce el dolor a la punción en igual magnitud y pueden ser usados indistintamente en la práctica odontológica diaria.

The objective of this study was to determine the effectiveness of benzocaine 20% gel and lidocaine in 10% solution in patients requiring puncture in the oral mucosa. This is a randomized controlled clinical trial to triple-blind, cross-over design. It was held at the dental clinic of the Unit of Second Specialization in Dentistry (usee) of the National University of Trujillo, in the months of November and December 2010 and January to March 2011. The sample consisted of 60 patients, each patient signed an informed consent and underwent a review of their status by anxiety scale state-trait anxiety (STAI). Before the puncture in the oral mucosa four preparations (2 topical anesthetics and 2 placebo) and then determine and compare the effectiveness of preparations in reducing pain using a visual analogue scale (VAS) was applied. For data collection a special token was used for that purpose. For comparison of the effectiveness of preparations Analysis of Variance (ANOVA). The effectiveness of the gel and anesthetic solution was evaluated using Tukey's test for multiple comparisons and students T. Statistical significance was 5%. We found that benzocaine 20% gel and lidocaine in 10% solution are effective at reducing pain at the puncture and that there is no statistically significant relationship (p= 0.0575) between the effectiveness of each. The administration of benzocaine 20% gel or lidocaine in 10% solution to reduce pain puncture equal and can be used interchangeably in everyday dental practice.
