Clinical Effectiveness of Ion-Releasing Restorations versus Composite Restorations in Dental Restorations: Systematic Review and Meta-Analysis.

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.

Association between Periodontal Disease and Obesity: Umbrella Review.

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.

Effects of some peruvian non-distilled alcoholic beverages on dental erosion / Efecto de algunas bebidas alcohólicas peruanas no destiladas sobre la erosión dental

Objective: To determine the erosive effect of pieces of permanent teeth exposed to non-distilled alcoholic beverages. Material and Methods: This study takes a quantitative approach, with an explanatory scope, descriptive and correlational, with a pure experimental design. The sample consisted of 45 premolar permanent teeth, which were randomly allocated to five sample groups. Every sample group was submerged in dark beer Cuzqueña Negra, wheat beer Cuzqueña de Trigo, lager beer Cerveza Cristal, lager beer Pilsen Callao and physiological saline solution; every solution had a quantity of 110 mL. The experiment was performed for five minutes, with three repetitions every 12 hours over a period of 70 days. The sampling was performed every seven days, using an analytical scale and a data sheet. Results: The average weight loss of dental pieces put in dark beer Cuzqueña Negra (pH 4.0) was 239.4456 mg. In lager beer Pilsen Callao (pH 4.6), it was 146.7867 mg. In lager beer Cerveza Cristal (pH 3.7), it was 131.3567 mg. In wheat beer Cuzqueña de Trigo (pH 4.5), it was 121.7122 mg. Lastly, in physiological saline solution (pH 6.8), it was 14.3311 mg. When applied to the sample, the statistical test Student's t-test resulted in a value of p≈0.000 (p<0.05). Conclusion: Non-distilled alcoholic beverages caused erosive effects in the pieces of permanent teeth.

Objetivo: : Determinar el efecto erosivo en dientes permanentes expuestos a bebidas alcohólicas no destiladas. Material y Métodos: Este estudio tiene un enfoque cuantitativo, con alcance explicativo, descriptivo y correlacional, con un diseño puramente experimental. La muestra consistió en 45 dientes permanentes premolares, que fueron asignados aleatoriamente a cinco grupos de muestra. Cada grupo de muestra se sumergió en cerveza Cuzqueña Negra, cerveza Cuzqueña de Trigo, Cerveza Cristal, cerveza Pilsen Callao y solución salina fisiológica; cada solución tenía una cantidad de 110 mL. El experimento se realizó durante cinco minutos, con tres repeticiones cada 12 horas durante un período de 70 días. El muestreo se realizó cada siete días, utilizando una escala analítica y una hoja de datos. Resultados: La pérdida de peso promedio de las piezas dentales colocadas en cerveza negra Cuzqueña Negra (pH 4,0) fue de 239,4456 mg. En la cerveza Pilsen Callao (pH 4,6), fue de 146,7867 mg. En la cerveza Cerveza Cristal (pH 3,7) fue de 131,3567 mg. En cerveza Cuzqueña de Trigo (pH 4,5), fue de 121,7122 mg. Por último, en suero fisiológico (pH 6,8) fue de 14,3311 mg. Cuando se aplicó la prueba estadística t de Student a la muestra dio como resultado un valor de p?0,000 (p<0,05). Conclusion: Las bebidas alcohólicas no destiladas causaron efectos erosivos en dientes permanentes.
