RESUMO

OBJECTIVES: Gerontological education and intergenerational contact are proven strategies for effectively combating ageism. In this context, this study investigates the association between gerontological education, intergenerational contact, and ageism among dental students. METHODS: Gerontological education from students' perspective, intergenerational contact, and ageism were assessed using a questionnaire containing sociodemographical aspects and an ageism scale (ASDS-Braz). The sample included students enrolled in the final year of dental programs at three public universities in southern Brazil. A multilevel Poisson regression was conducted to assess factors associated with ASDS-Braz scores. RESULTS: A modest correlation was identified between dental schools in terms of reducing ageism, and a weak correlation was found between self-reported race and ageism. Notably, statistically significant findings were observed across family relationship with older individuals: students who reported having a poor relationship with older adults in their families presented 45% higher ageism scores than did those with an excellent relationship. CONCLUSION: The results suggested that while some gerontological education was reported by the participants, it may not be sufficient to prepare dental students to provide effective oral healthcare to older adults and to reduce ageism among them. Additionally, reinforcing positive aspects of intergenerational relationships may be an additional strategy in combating ageism within this population.

RESUMO

OBJECTIVES: There is a scarcity of randomized clinical trials (RCT) that report medium- and long-term results and a lack of consensus in the literature on the predictability of immediately loaded unsplinted narrow diameter implants supporting mandibular overdentures. This RCT compared the performance of conventional (CL) and immediate loading (IL) of mandibular overdentures retained by two narrow-diameter implants for 3 years. MATERIALS AND METHODS: Patients from an RCT treated with CL or IL were invited to attend to 2- and 3-year follow-ups. Clinical, radiographic, functional, and oral health-related quality of life parameters were evaluated. Prosthetic maintenance events, biological complications, and success and survival rates were also recorded. The data were tested by multilevel mixed-effects linear regression analysis and chi-squared tests. RESULTS: The 1-year survival rates of 90% in the CL group and 85% in the IL group were maintained as no implants were lost between 1 and 3 years. The marginal bone loss (MBL) in the IL group was significantly lower after year 3 (-0.04; p < 0.01). Significant changes were found only for the intra-group comparisons in the third year of function: (i) CL and IL presented similar progression of implant stability, MBL, and posterior bone area resorption; (ii) while CL started deteriorating of masticatory function, IL still exhibited functional evolution and (iii) oral comfort domain in the CL and pain domain in the IL were improved. CONCLUSION: Although IL experienced the lowest MBL after 3 years, the outcomes showed that both loading protocols result in predictable medium-term rehabilitation when monitored annually. CLINICAL RELEVANCE: It can be expected that in the third year of function, patients with immediate loading may present more complaints related to general performance even with acceptable masticatory function and self-reported improvements in oral comfort.

RESUMO

RESUMO As intervenções fonoaudiológicas podem ser influenciadas pela forma como se pensa, sente e fala sobre a morte e o morrer. A literatura sugere que o (futuro) fonoaudiólogo deve aprender a administrar suas respostas emocionais relacionadas à morte e ao morrer e ampliar suas perspectivas para considerar a morte e o morrer como parte da experiência humana, por meio de estratégias formativas reflexivas e de aprendizagem experiencial, assemelhando-se às características de um Death Cafe, tornando seu uso formativo potencialmente aplicável neste contexto. O Death Cafe é uma franquia social global com regras preestabelecidas, em que as pessoas se reúnem para discutir livremente a morte como parte da vida, sem objetivos ou temas predefinidos, distinguindo-se do apoio ao luto, palestras e afins. Estudos discutem os benefícios da participação de estudantes e profissionais de saúde em Death Cafe, incluindo a transformação da morte numa perspectiva naturalista, a exploração da humanidade do morrer, a reavaliação de como abordam e querem abordar os cuidados de fim de vida, a gestão das emoções e a melhoria do julgamento clínico.

ABSTRACT Speech therapy interventions may be influenced by how one thinks, feels, and talks about death and dying. The literature suggests that the (future) speech therapist should learn how to manage their emotional responses related to death and dying and broaden their perspectives to consider death and dying as part of the human experience through reflective formative strategies and experiential learning, resembling the characteristics of a Death Cafe. This makes its formative use potentially applicable in this context. The Death Cafe is a global social franchise with pre-established rules, where people gather to freely discuss death as a part of life, without predefined objectives or themes, distinguishing it from grief support, lectures, and the like. Studies discuss the benefits of students and healthcare professionals participating in Death Cafe, including transforming death into a naturalistic perspective, exploring the humanity of dying, reassessing how they approach and want to approach end-of-life care, managing emotions, and enhancing clinical judgment.

RESUMO

BACKGROUND AND OBJECTIVE: Parkinson's disease is a neurological disorder that affects 1% of individuals aged 60 years and older. The associated symptoms can impose limitations on the available dental treatment options. CASE DESCRIPTION: This case report follows the CARE guidelines and presents an adapted and simplified technique to fabricate complete dentures for a 74-year-old male edentulous patient with Parkinson's disease. This modified technique enabled the fabrication of complete dentures in 4 clinical sessions of approximately 40 minutes. The first session involved manufacturing a preliminary impression with fast-setting alginate. The base plates and occlusal rims were then adjusted for artificial teeth arrangement during the second session. The final prosthesis was completed in the third session, which involved a teeth try-in and fabrication of a functional impression with low-melting thermoplastic material and polyether. Finally, denture installation was performed in the fourth session and follow-up consisted of 3 weekly sessions. DISCUSSION: Considering that the treatment provided satisfactory aesthetics and function, mastication and socialization benefits, and improved the self-esteem and well-being of the older patient with Parkinson's disease, the authors suggest this adapted and simplified technique for fabricating complete dentures.

RESUMO

OBJECTIVES: This cohort study investigated clinical, functional, and quality of life outcomes, along with prosthetic maintenance events in mandibular overdenture (MO) wearers for 3 years. METHODS: Thirty MO wearers with narrow diameter implants (NDIs) and locking taper stud abutments (Facility-Equator system) were annually monitored by registering the visible plaque index (VPI), peri­implant inflammation (PI), calculus presence (CP), probing depth (PD), bleeding on probing (BOP), secondary implant stability (ISQ), marginal bone loss (MBL), masticatory performance and dental impact in daily life (DIDL) questionnaire domains. Multilevel mixed-effects linear regression was performed to analyse changes over time. Chi-square tests were performed to analyse the relationship between the appearance of prosthetic complications and maintenance occurrences. The survival rate of patients with NDIs was calculated using the Kaplan-Meier test. RESULTS: Twenty-six individuals attended all follow-ups, the survival rate of 83.3% in the first year was maintained, and no one implant was lost over the 3-year period. There were significant differences for PD between 1 and 3 years (p ≤ 0.01) and between 2 and 3 years for PI (p ≤ 0.01), GI (p ≤ 0.01), ISQ (p = 0.02), and MBL (p ≤ 0.01). All masticatory performance outcomes showed significant differences (p ≤.01). Prosthetic maintenance events decreased significantly over time. Appearance, general performance, and eating and chewing domains presented high effect sizes. CONCLUSION: Continued changes were observed in the clinical parameters of MO users over the 3-year period. In addition, most functional parameters, except for particle homogenization, improved significantly over time. The positive impact on quality of life is likely related to the significant reduction in prosthetic maintenance events. CLINICAL SIGNIFICANCE: Periodic returns to assess peri­implant tissues and MO maintenance should be performed to ensure the success of rehabilitation to assure improvements in masticatory function and oral health-related quality of life.

RESUMO

Background: Facial types may interfere in the oral health-related quality of life (OHRQoL) and masticatory performance of implant-retained mandibular overdenture (IMO) wearers. Purpose: Investigate the medium-term changes in the masticatory function (MF) and OHRQoL parameters of IMO users, as a function of facial pattern, anteroposterior skeletal discrepancy, and sex. Methods: Forty IMO users, most of them Caucasian (90%) with average age of 69.17 years were classified according to their facial pattern and antero-posterior discrepancy prior to rehabilitation. MF was evaluated by the multiple sieves method to determine the average particle size (X50), heterogeneity (B) and masticatory efficiency (ME, calculated as the percentage of material retained in the 5.6 and 2.8 mm sieves), using Masticatory performance (MP) and swallowing threshold (ST) tests. OHRQoL was measured by applying the dental impact on daily life (DIDL) questionnaire. The data were analyzed by Wilcoxon-paired tests to analyze changes in MF parameters over time, and mixed-effect multilevel regression models were employed to verify differences between groups. Results: Significant changes were still observed in the 3rd year for the ST test with improvements in B for Mesofacial and in time for Dolichofacial individuals, while ME_2.8 deteriorated for Brachyfacial participants. B values of Class I and male individuals improved and brachyfacial individuals still presented worse homogenization (B) than Mesofacial participants in both masticatory tests. Class II and III participants still showed improvements in ME_5.6 and time compared to Class I despite increases in X50. Class II individuals needed less cycles than Class I in the 3rd year. Brachyfacial participants scored lower in the Appearance domain than Mesofacial ones in the 3rd year. Dolichofacial participants and Class III patients scored lower in the Oral Comfort domain than Mesofacial and Class I, respectively. In addition, age influenced the Pain, Oral Comfort and General Performance domains in the 3rd year. Conclusions: Differences in facial morphology continue to influence the MF and OHRQoL outcomes in the 3rd year, and age influenced some OHRQoL domains. Brachyfacial individuals continue to benefit least from rehabilitation with IMO according to masticatory parameters.

RESUMO

The use of mandibular overdentures (MO) for the rehabilitation of totally edentulous individuals with limited bone availability is widespread and has proven clinical success. Narrow diameter implants (NDI) are available on the market as MO retainers to solve problems related to limited bone availability and bone thickness, providing a low-cost, minimally invasive treatment option. This technique evolved over the years, and changes frequently involved the number of implants used as MO retainers, as the adoption of a smaller number of implants can generate biomechanical disadvantages, contributing to the increased stress in peri-implant tissues, which may accelerate marginal bone loss (MBL), in addition to reducing masticatory capacity and satisfaction with rehabilitation. Some studies pointed out that the use of 3 or more implants as MO retainers improves the biomechanics. Thus, the objective of this study was to report 3 different clinical cases where 3 or more NDI were adopted to retain mandibular overdentures in association with diverse loading protocols: (i) 3 implants adopting conventional loading, (ii) 4 implants using progressive loading, and (iii) 4 implants with hybrid loading. The case with 4 implants and progressive loading showed a slight worsening of masticatory function at 1 year, in addition to a more pronounced MBL compared to other cases, but with improvements in satisfaction and oral health-related quality of life. Thus, NDI can be used as MO retainers with predictability and clinical success, using different numbers of implants and loading protocols.

RESUMO

STATEMENT OF PROBLEM: The degree of mandibular bone atrophy can guide and determine the choice of prosthetic treatment. Although several methodologies have been proposed for classifying atrophy, the clinical and radiographic parameters considered for the classification of mandibular bone atrophy should be standardized. PURPOSE: The purpose of this clinical study was to evaluate the influence of methodologies of mandibular bone atrophy categorization on the masticatory function in complete denture (CD) wearers and to verify the relationship between these parameters according to the retention and stability of the mandibular CD. MATERIAL AND METHODS: CD wearers were radiographically and clinically evaluated to determine the mandibular bone atrophy levels. Three classifications were adopted: the Cawood and Howell criteria, the Wical and Swoope criteria, and the Kapur classification. CD retention and stability were scored based on the Sato et al method. The masticatory function was evaluated by the multiple sieve method using optical test food to determine the masticatory performance (MP) indexes (median particle size, MP X50; homogeneity index, MP B) and the masticatory efficiency (sieves 4 and 2.8). RESULTS: In this sample of 63 individuals (mean age of 67.4 years), atrophic participants presented significant differences in all radiographic parameters (Mann-Whitney test, P<.05) with both the Cawood and Howell and Wical and Swoope methodologies. No differences in masticatory function were found, except for atrophic participants classified by Wical and Swoope criteria, who had worse MP X50 (P=.047) than nonatrophic participants, with a medium effect size of 0.7. The retention of the mandibular CD significantly affected the masticatory outcomes, with higher values for MP X50 (P=.012) and MP B (P=.040) and lower values for masticatory efficiency, 2.8 (P=.008) for atrophic participants. The presence of mandibular bone atrophy showed an association with poor retention (P=.04) and poor stability (P=.002) when the Cawood and Howell criteria were adopted (Fisher exact test, P<.05). CONCLUSIONS: The Kapur classification confirmed the clinical condition of the participants' atrophy, and the most clinically atrophic participants showed poor retention and stability of the mandibular CD. Only the poor retention directly affected the masticatory function. Radiographic evaluations alone did not provide sufficient data to determine the predictability of CD treatment regarding the participants' masticatory function. Radiographically, atrophic participants with poor retention had impaired mastication.

RESUMO

Aim: The prevalence of denture stomatitis and the relationship with its risk factors was evaluated via secondary data from 62 complete denture (CD) wearers, between 2015 and 2017. Methods: The data was stored in an Excel database and was analyzed using the statistics software STATA/SE 12.0. A descriptive analysis was performed taking into account a categorization of the clinical variables according to risk factor in 4 domains: CD usage, systemic health, hygiene habits, and usage habits. The association amongst the denture stomatitis and risk factors variables was tested by the Chi-square test and the results were statistically significant at p-values <0.05. Results: The CD wearers participants were composed by a majority of elderly (80.64%) and women (72.78%); with 45.16% having been using the current denture for more than 10 years and another 74.19% related a continuous usage. Diabetes and hypertension were related by 83.87% and 67.74%, respectively, with 87.10% using medication. Although 75.80% reported cleaning their dentures 3 times per day or more, and 59.68% considered their oral hygiene very good, 50% of the complete dentures showed dirtiness and clinical signs of Denture Stomatitis were present in 30.64% of the patients. Despite of the evaluated sample shows many risk factors for the development of the disease, an association between the variables was not observed. Conclusion: Considering the high prevalence of the disease in the studied sample, preventive and educational measures on denture usage and hygiene must be reinforced in order to maintain the oral health of the edentulous patients

RESUMO

PURPOSE: Evaluate how clinical factors related to conventional complete denture (CCD) wearers, can influence masticatory function (MF) of totally edentulous patients before and after one-year transitioning to implant-retained mandibular overdentures (IMO). METHODS: Forty patients using CCD were rehabilitated with IMO and their MF was evaluated by: (i) ST_X50: theoretical aperture through which 50% of the weight of the particles would pass; (ii) STB: distribution homogeneity of the crushed particles. The clinical parameters analyzed were: atrophy, retention, stability, facial type, anteroposterior skeletal discrepancy, and type of loading. The statistical association was tested through crude and adjusted logistic regression. RESULTS: IMO promoted improvements in the MF, irrespective of the clinical parameters. CCD wearers with poor retention had 86% less chance of achieving a good ST_X50. STB was associated with stability, facial type, and anteroposterior discrepancy. Subjects with poor mandibular CCD stability had a 76% lower chance of achieving a good test food homogenization, whereas brachyfacial individuals were 1.3 times more likely to have a good STB. Class II patients had an 89% lower chance of having a good homogenization of the particles as CCD users and after transition to IMO. CONCLUSIONS: CCD users with poor retention achieved an inferior ST_X50. The STB performance can be compromised by poor stability or Class II characteristics, while brachyfacial individuals achieve better homogenezation of the food bolus. Although the transition to IMO improved the masticatory function, the anteroposterior discrepancy still maintained an association with STB, as Class II individuals still presented difficulties homogenizing food.
