RESUMEN

STATEMENT OF PROBLEM: Denture adhesives improve the mastication of complete denture wearers. However, the impact of denture adhesives with different presentations on mastication remains unclear. PURPOSE: The purpose of this systematic review was to answer the focused question, "Do different presentations of denture adhesives affect the masticatory function of complete denture wearers?". MATERIAL AND METHODS: This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Six databases and the non-peer-reviewed literature were searched up to July 2021. Only clinical studies (randomized clinical trials and nonrandomized clinical trials) comparing the use of different denture adhesive presentations (cream, powder, or strips) were included, without language or follow-up restrictions. The risk of bias was assessed by using the Cochrane tools (RoB 2.0 and ROBINS-I). Masticatory performance, by using single and multiple sieves, masticatory performance with color-changing chewing gum (mixing ability), swallowing threshold (particle size and number of cycles), jaw kinematics, and occlusal force were considered. Meta-analyses were conducted to evaluate masticatory performance (single sieve) and occlusal force outcomes (α=.05), and the certainty of the evidence was determined with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) evaluations. RESULTS: Nine studies (6 randomized and 3 nonrandomized clinical trials) were included. The risk of bias was considered moderate. Meta-analyses showed no differences between cream and powder denture adhesives for masticatory performance (standard mean difference=0.02; 95% CI=-0.46 to 0.50, P=.93) or between cream and strip denture adhesives for occlusal force (mean difference=14.35; 95% CI=-11.14 to 39.84, P=.27). Similarly, in qualitative analysis, cream and powder denture adhesives' performances were similar regarding masticatory performance with color-changing chewing gum (mixing ability), occlusal force, swallowing threshold (particle size and number of cycles), and jaw kinematics (P>.05). However, for resorbed ridges, cream denture adhesive resulted in a higher masticatory performance than strip (P<.05). When comparing powder to strip denture adhesives, the occlusal force was higher in the powder group (P<.05). The certainty of evidence was very low for all evaluated outcomes. CONCLUSIONS: Different presentations of denture adhesives seem to improve the masticatory function of complete denture wearers in a similar way. However, the qualitative analysis showed that, in patients with a resorbed ridge, a cream denture adhesive may be better than strips to improve mastication, although the certainty of evidence was very low.

RESUMEN

OBJECTIVE: This cross-sectional study aimed to evaluate the association of oral health-related quality of life with prosthetic rehabilitation status and dental prosthesis condition in residents of Brazilian long-term care facilities. METHODS: The oral health-related quality of life of older adults (n = 194; mean [standard deviation] age = 78.93 [9.10]) was assessed by the Geriatric Oral Health Assessment Index and the Oral Health Impact Profile questionnaires. Prosthetic rehabilitation status was recorded according to the absence of teeth and use of dental prostheses. Dental prosthesis condition was considered good or poor based on stability, retention, occlusion, vertical dimension, and defects. Poisson regression models were plotted to analyze the data (α = 0.05). RESULTS: Lower Geriatric Oral Health Assessment Index scores were associated with edentulism with denture use only on one jaw (B = -0.05) and poor dental prosthesis stability (B = -0.04). Similarly, edentulous participants with denture only on one jaw (B = 0.59) and those wearing dental prostheses with poor stability (B = 0.36) are more likely to achieve higher Oral Health Impact Profile scores. Also, lower Oral Health Impact Profile scores were associated with denture defects (B = -0.34). CONCLUSION: In summary, the oral health-related quality of life of older adults living in long-term care facilities is negatively impacted by edentulism with denture only on one jaw and use of dental prostheses with poor stability. Therefore, long-term care facilities should provide oral health training to caregivers, include dental professionals in the staff, and articulate demands with oral health teams in the primary care system.

OBJETIVO: Este estudo transversal objetivou avaliar a associação da qualidade de vida relacionada à saúde bucal com o status de reabilitação protética e a condição da prótese em residentes de instituições de longa permanência no Brasil. METODOLOGIA: A qualidade de vida relacionada à saúde bucal dos idosos (n = 194; média [desvio padrão] idade = 78,93 [9,10]) foi avaliada pelos questionários Geriatric Oral Health Assessment Index e Oral Health Impact Profile. O status de reabilitação protética foi registrado de acordo com a ausência de dentes e uso de próteses dentárias. A condição da prótese foi considerada boa ou ruim com base na estabilidade, retenção, oclusão, dimensão vertical e defeitos. Modelos de regressão de Poisson foram plotados para analisar os dados (α = 0,05). RESULTADOS: Como resultado, menores escores no Geriatric Oral Health Assessment Index foram associados ao edentulismo com o uso de dentadura em apenas uma arcada (B = -0,05) e ao uso de próteses com estabilidade ruim (B = -0,04). De forma similar, participantes edêntulos que usavam dentadura em apenas uma arcada (B = 0,59) e aqueles que portavam prótese com estabilidade ruim (B = 0,36) são mais propensos a ter maiores escores no Oral Health Impact Profile. Além disso, menores escores no Oral Health Impact Profile foram associados a defeitos na prótese (B = -0,34). CONCLUSÃO: Sumarizando, a qualidade de vida relacionada à saúde bucal de idosos residentes em instituições de longa permanência é negativamente impactada pelo edentulismo com o uso de dentadura em apenas uma arcada e uso de prótese com estabilidade ruim. Assim, instituições de longa permanência devem promover capacitação em saúde bucal aos cuidadores, incluir dentistas no quadro de funcionários e articular com as equipes de saúde bucal da Atenção Primária à Saúde.

RESUMEN

Aim: This cross-sectional observational study aimed to evaluate the influence of the Universities lockdown measures on academic perspectives and psychosocial aspects of Brazilian finalyear dental students. Methods: 268 undergraduate students regularly enrolled in a Dentistry course at public universities were asked about anxiety, depression, stress sensitivity, and their academic perspectives by using an online survey. The Hospital Anxiety and Depression Scale (HADS) was used to measure anxiety and depression, while the Perceived Stress Scale (PSS) evaluated stress levels. The academic perspective was evaluated by five affirmatives regarding possible difficulties that will be faced when school reopens and after graduation. The possible association between fear of having COVID-19 with psychosocial outcomes and COVID-19 association with academic perspectives were analyzed by ANOVA and chisquare tests, respectively, considering a significance level of 5%. Results: Considering possible associations between the fear of having COVID-19 and psychosocial aspects, significant values were found for anxiety (P = 0.018) and stress sensitivity (P = 0.002). Regarding students' academic perspectives, COVID-19 had significant impact on less opportunity to perform procedures (P = 0.023), additional expenses with personal protective equipment (P = 0.007), and concerns of consulting elderly people (P = 0.012). Conclusion: The COVID-19 pandemic led to increased psychological impairments and enlarged concerns with learning and biosecurity, which might impact academic perspectives. Thus, being aware of these apprehensions, university professors and staff can improve the clinical training of final-year dental students in an empathetic way

RESUMEN

OBJECTIVE: To evaluate the association of masticatory function with prosthetic rehabilitation status and dental prosthesis functionality in nursing home residents. BACKGROUND: Prosthetic rehabilitation status and dental prosthesis functionality may adversely affect mastication of older people, and this relationship is underestimated in nursing home residents. MATERIALS AND METHODS: This cross-sectional study included 179 nursing home residents who used dental prostheses [mean (SD) age: 78.9 (9.0) years]. Masticatory function data were determined by assessing (a) masticatory performance using two-colour chewing gum, and (b) swallowing thresholds by counting the number of peanut chewing cycles. Older adults were categorised as: (1) using dental prostheses in both jaws (n = 100) and (2) partially dentate using removable partial dental prostheses (RPDPs) or complete dentures (CDs) in only one jaw (n = 41), or (3) edentulous using CD in only one jaw (n = 38). Stability, retention, occlusion, vertical dimension and defects were considered in assessing dental prosthesis functionality. RESULTS: Greater variance of hue (VOH) of the chewing gum and lower swallowing thresholds (worse masticatory function) was associated with edentulous using CD in only one jaw. Older adults wearing dental prostheses with poor occlusion and vertical dimensions presented worse masticatory function. Dental prosthesis stability was associated with lower VOH values. Higher number of chewing cycles while eating peanuts was associated with non-broken dental prosthesis use. CONCLUSION: Edentulous participants using CD in only one jaw and non-functional dental prosthesis use negatively affect the masticatory function of nursing home residents.

RESUMEN

Abstract This study aimed to evaluate the correlation between two Oral Health-Related Quality of Life (OHRQoL) questionnaires (the Oral Health Impact Profile (OHIP-14) and the Geriatric Oral Health Assessment Index (GOHAI)) and to investigate the factors associated with the OHRQoL of institutionalized elderly individuals. A cross-sectional multicenter study was performed with 344 institutionalized elderly individuals residing in two Brazilian cities. Six trained researchers interviewed the elderly individuals. Sociodemographic data were collected from medical records. Dental caries experience and the use of and need for dentures were recorded through oral examination performed by two trained examiners. A Likert scale (1-5 points) was used to assess general health and self-perceived oral health. The number of chewing cycles needed to chew a portion of peanuts was used to assess the swallowing threshold. The OHIP-14 and GOHAI were used to evaluate OHRQoL, and statistically significant correlations were assessed using Spearman's correlation test (p < 0.05). Poisson regression (p < 0.05) was used to investigate the association of OHRQoL with independent variables. Scores on the OHIP-14 (7.57 ± 8.63) and GOHAI (32.46 ± 3.85) were strongly and inversely correlated (r2 = -0.671, p < 0.001), although these measures were associated with different factors. A higher OHIP-14 total score (worse OHRQoL) was associated with female gender, a greater number of healthy teeth, worse self-perceived general health and oral health, and a lower swallowing threshold (p < 0.05). A higher GOHAI total score (better OHRQoL) was associated with a greater number of filled teeth, better self-perceived oral health and a greater swallowing threshold (p < 0.05). In conclusion, worse OHRQoL among institutionalized elderly individuals is associated with worse self-perceived oral health and a greater swallowing threshold.

RESUMEN

OBJECTIVES: This multicenter cross-sectional study aimed to investigate the factors associated with the overlap of frailty and nutrition in older adults residing in nursing homes. METHOD: Older adults (n = 344, mean age ±â€¯SD = 77.7 ±â€¯9.1) were selected from 17 nursing homes, 10 in Piracicaba and seven in João Pessoa, Brazil. The modified Fried's questionnaire and the Mini Nutrition Assessment Short-Form (MNA-SF) were used for screening frailty phenotypes and nutritional status, respectively. These variables overlapped into (1) frail and malnourished; (2) nonfrail and malnourished or frail and nourished; and (3) nonfrail and nourished. The independent variables were sex, age, mobility, number of medications, dependence for activities of daily living (ADL), maximal grip strength, muscle mass, body fat and body mass index (BMI). Spearman's correlation and Poisson regression were used to analyze the data (α = 0.05). RESULTS: The Spearman's test demonstrated a moderate correlation (r2=-0.441) between frailty (mean ±â€¯SD = 2.8 ±â€¯1.7) and nutritional status (mean ±â€¯SD = 10.5 ±â€¯2.9). Regarding the overlap of frailty and nutrition, 139 participants (40.5 %) were frail and malnourished, 121 (35.3 %) were nonfrail and malnourished or frail and nourished, and 83 (24.2 %) were nonfrail and nourished. The Poisson regression showed association of the coexistence of frailty and malnutrition with age (PR = 1.009, 95 % CI = 1.003-1.016), number of medications (PR = 1.016, 95 % CI = 1.006-1.027), dependence for ADL (PR = 1.061, 95 % CI = 1.016-1.108), maximal grip strength (PR = 0.992, 95 % CI = 0.986-0.998) and BMI (PR = 0.997, 95 % CI = 0.996-0.998). CONCLUSIONS: The findings showed that frailty and malnutrition were prevalent in institutionalized older adults and associated with advanced age, greater use of medicines, dependence for ADL, lower maximal grip strength and lower BMI.

RESUMEN

Oral rehabilitation with mandibular single-implant overdentures (SIO) has been characterized as a solution to improve retention and stability of conventional complete dentures (CD). Among the benefits of this therapy, it can be mentioned minimally invasive surgery, simple prosthetic technique, better retention, and significantly reduced costs. However, the application of this protocol in daily clinic is still not widespread. Aim: Thus, this study aimed to perform a literature review to address the clinical characteristics of this rehabilitation, when compared to two-implant mandibular overdentures and CD. Methods: For this, a search was conducted in the PubMed database, considering articles published in English language, without date limitation. Results: It was found 243 manuscripts, of which 20 were compatible with the aim of this study after title/abstract reading. The selected papers focused on masticatory muscles function, satisfaction levels and self-reported quality of life, as well as surgical and prosthetic outcomes, such as maintenance, repair and implant failure rates. All evaluated manuscripts showed similar masticatory function and patient's satisfaction with SIO and two-implant overdenture, while results for a SIO were greater when compared to rehabilitations with CD. In addition, SIO have proven to do not damage the implant, being implant loss close to zero. However, the prosthesis fracture adjacent to the implant was a recurrent clinical outcome, which requires further studies to solve this impairment. Conclusion: Thus, it can be concluded that SIO represents an alternative treatment for frail elders or low-income patients, leading to higher masticatory function, as well as improved quality of life

RESUMEN

A reabilitação protética por meio de implantes tem se confi gurado como o padrão-ouro para a devolução da função previamente perdida pelo paciente, podendo ser realizada com próteses removíveis ou fixas sobre os implantes osseointegrados. As próteses fixas do tipo protocolo proporcionam maior estabilidade durante as atividades cotidianas, como falar e comer, além de alta performance estética, quando bem indicada. Vislumbrando uma maior resistência das próteses, melhor harmonização do sorriso e adequada adaptação, as infraestruturas em zircônia vêm sendo altamente difundidas na literatura. Confeccionadas pelo método CAD/CAM, as próteses em zircônia dispensam as etapas de solda, o que elimina possíveis distorções de grandes estruturas, além de serem produzidas mais rapidamente e com uma estética maior, caracterizando-se como a melhor opção para pacientes que buscam a mimetização do sorriso natural.

The prosthetic rehabilitation using dental implants has been featured as the gold standard for retrieving patient's lost function, and may be performed by implant-supported removable or fixed dental prostheses. The implant-supported fixed prosthesis provides greater stability during daily activities, such as talking and eating, and high aesthetic performance, when properly indicated. In order to obtain higher resistance, superior smile esthetics and adequate prosthesis fit, the zirconia infrastructure have been highly disseminated in the literature. The CAD/CAM zirconia prosthesis avoids welding/soldering, which eliminates possible distortions of large structures. In addition, it is produced faster and with greater aesthetic, being nowadays characterized as the best option for patients who seek to emulate the natural smile.
