Prosthetic rehabilitation with removable dentures positively influences quality of life in older patients: a systematic review / A reabilitação protética com próteses removíveis influencia positivamente a qualidade de vida de pacientes idosos: uma revisão sistemática

OBJECTIVE: This systematic review assessed the effects of prosthetic rehabilitation with removable dentures on oral health-related quality of life (OHRQoL) in older adults. METHODS: A comprehensive electronic search was conducted in the PubMed/MEDLINE, Web of Science, and Cochrane databases to identify randomized clinical trials and prospective clinical studies. The included studies evaluated the effects of prosthetic rehabilitation on OHRQoL in patients whose mean age was > 60 years. The interventions included complete dentures, implant-retained overdentures, and removable partial prostheses, with a minimum follow-up period of 1 month after prosthetic rehabilitation. Patient-reported outcome measures, specifically OHRQoL, were the primary outcome. Risk of bias was assessed using the Cochrane RoB 2 tool for randomized clinical trials and the ROBINS-I tool for prospective clinical studies. RESULTS: Eleven articles were considered eligible for the systematic review. The findings indicated that removable dentures improved various OHRQoL domains, mainly functional limitations and physical and psychological disabilities. Retention, stability, comfort, speech, and masticatory efficiency were significantly better with implant overdentures than complete dentures, leading to higher patient satisfaction and OHRQoL. CONCLUSIONS: This systematic review suggests that prosthetic rehabilitation with removable dentures has a positive influence on OHRQoL in older patients. The findings highlight the beneficial impact of implant overdentures and fixed adhesive prostheses for enhancing functional outcomes and patient satisfaction.

METODOLOGIA: Foi realizada uma pesquisa eletrônica abrangente nas bases de dados United States National Library of Medicine/ Medical Literature Analysis and Retrieval System Online ­ PubMed/MEDLINE, Web of Science e Cochrane para identificar ensaios clínicos randomizados (ECR) e estudos clínicos prospectivos. Os artigos selecionados tiveram como foco avaliar o efeito da reabilitação protética na QVRSB em indivíduos com média de idade superior a 60 anos. As intervenções descritas incluíram próteses totais, overdentures suportadas por implantes e próteses parciais removíveis, com acompanhamento mínimo de um mês após a reabilitação protética. As medidas de resultados relatadas pelos pacientes, especificamente QVRSB, foram o desfecho primário. O risco de viés foi avaliado com a ferramenta Cochrane RoB 2 pare ensaios clínicos randomizados e a ferramenta ROBINS-I para estudos clínicos prospectivos. RESULTADOS: Os resultados mostraram que as próteses dentárias removíveis melhoraram vários domínios da QVRSB, principalmente limitações funcionais e físicas e deficiências psicológicas. A retenção, estabilidade, conforto, fala e eficiência mastigatória foram significativamente melhores com overdentures sobre implantes do que com próteses totais, levando a maior satisfação do paciente e QVRSB. CONCLUSÕES: Esta revisão sistemática sugere uma influência positiva da reabilitação protética com próteses removíveis na QVRSB em pacientes idosos. As descobertas destacam o impacto benéfico das overdentures sobre implantes e das próteses adesivas fixas para melhorar os resultados funcionais e a satisfação do paciente

Intentional foraminal enlargement: a systematic review with bibliometric analysis / Ampliação foraminal intencional: uma revisão sistemática com análise bibliométrica

Objective: The purpose of this systematic review with bibliometric analysis was to map the available scientific evidence on intentional foraminal enlargement (IFE) and explore publication trends. Methods: This review is in accordance with the PRISMA 2020 Statement and is registered on the Open Science Framework. Two independent reviewers carried out a comprehensive search of seven databases (PubMed/MEDLINE, Cochrane Library, Scopus, Embase, Web of Science, LILACS, and BBO) up to January 31 st, 2022. Studies that investigated IFE were considered eligible, and the data were analyzed using the VOSViewer software. Results:The search identified a total of 55 IFE-related articles from 10 countries and 25 journals, with an increasing trend for publications over the last decade. The majority of evidence was based on laboratory assays (65.4%), followed by randomized clinical trials (18.1%) with follow-up periods of up to 2 months. The main clinical outcome evaluated was post-operative pain. The highest number of studies were carried out by the State University of Campinas, and published in the Journal of Endodontics. Also, studies with the highest level of evidence found that IFE resulted in greater post-operative pain in the initial days post-treatment. Conclusion:This systematic review with bibliometric analysis mapped the scientific progress and publication trends in the field of IFE, thus shedding light on gaps in the literature with the aim of guiding researchers to conduct more high-impact investigations by performing clinical studies evaluating rates of periapical repair and IFE treatment success using long-term observation periods (AU)

Effect of alpha-humulene incorporation on the properties of experimental light-cured periodontal dressings

Abstract The objective of this study was to formulate an experimental light-cured periodontal dressing containing alpha-humulene and to compare its physical, antimicrobial, and cytotoxicity properties with commercial gold standards (Barricaid® and Periobond®). Two periodontal dressing formulations were developed (a and b). The formulations were divided into 5 groups according to the alpha-humulene concentration as follows: Ea - control group, Ea1 - 1%, Ea5 - 5%, Ea10 - 10%, and Ea20 - 20%; Eb - control group, Eb1 - 1%, Eb5 - 5%, Eb10 - 10%, and Eb20 - 20%. Materials characterization was performed using the degree of conversion, cohesive strength, sorption, and solubility assays. Antimicrobial assay was performed using the modified direct contact test against E. faecalis and S. aureus. Cytotoxicity was assessed by the cell viability experiment using L929 fibroblasts. In general, the cohesive strength values of materials decreased as the alpha-humulene concentration increased. All the experimental dressings showed antimicrobial activity against both bacteria tested. Cell viability results for the Ea, Ea1, Eb, and Eb1 groups showed moderate cytotoxic effect. The formulations containing alpha-humulene showed similar behavior to the commercial references. Thus, formulations containing alpha-humulene have potential to be used as periodontal dressing.

As for mechanical properties, Fuji IX was the only GIC that showed an increase in compressive strength during the evaluation period of 28 days. Ketac Molar showed the highest cell viability, while Maxxion R showed severe cytotoxicity and the highest cumulative fluoride release value. Conclusion: Fuji IX and Ketac Molar showed the most appropriate physical and biological properties among the evaluated GICs.(AU)

Evaluation of dentin hypersensitivity treatment with glass ionomer cements: A randomized clinical trial

Abstract A randomized, double-blind, split-mouth clinical trial was performed compared the desensitizing efficacy of the resin-modified glass ionomer cement (GIC) ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional GIC Vidrion R (SS White, Gloucester, UK) in a 6-month follow-up. Subjects were required to have at least two teeth with dentin hypersensitivity. Teeth were divided at random into 2 groups, one group received Clinpro XT and the other conventional GIC Vidrion R. Treatments were assessed by tactile and air blast tests using Visual Analogue Scale (VAS) at baseline, after 20 minutes, and at 7, 15, 21, 30, 90 and 180 days post-treatment. Twenty subjects (152 teeth) were included. Both tests (tactile and air blast) showed a significant reduction of dentin hypersensitivity immediately after the application of Vidrion R and Clinpro XT (20 min). VAS scores obtained along the 6-month follow-up were statistically lower when compared to initial rates (p < 0.05). Both GIC were able to reduce dentin hypersensitivity up to 6-month post-treatment period without statistically significant differences among them (p > 0.05). Both cements provided satisfactory results in long-term dental sensitivity reduction.
