RESUMEN
OBJECTIVE: This study aimed to explore the cross-sectional and prospective associations between self-reported functionality of complete dentures (FCD), satisfaction with complete dentures (SCD) and the ability to chew hard food (ACHF) on the one hand and the frailty index (FI) on the other hand among edentulous community-dwelling older Japanese people. METHODS: The study examined 770 edentulous participants of the Nihon University Japanese Longitudinal Study of Aging. The self-reported FCD, SCD and ability to chew six groups of food (from hardest to softest) with complete dentures were the independent variables at the baseline. The FI was computed including 40 deficits as the dependent variable at the baseline and 4 years later. Cross-sectional and prospective generalized linear regression models were fitted controlling for age, gender, marital status, education, working status and area of residence. RESULTS: The use of non-functional complete dentures and dissatisfaction with complete dentures were both associated with a higher FI cross-sectionally (3.9% [95% CI 2.2-5.6] and 3.2% [95% CI 1.5-4.9], respectively) and prospectively (3.9% [95% CI 2.0-6.0] and 3.3% [95% CI 1.3-5.3], respectively). Regarding the ability to chew, a higher FI at baseline was observed among those able to chew food of Group 2 (1.9%, [95% CI 0.1-3.7]) and Groups 4-6 (1.9%, [95% CI 0.1-3.7]), and a progressive increment in the FI, as the participants reported being able to chew softer groups of food at the follow-up (Group 2: 2.2% [95% CI 0.05-4.3]; Group 3: 3.6% [95% CI 1.2-6.0]; and Groups 4-6: 3.4 [95% CI 0.7-6.1]). CONCLUSION: Self-reported use of non-functional complete dentures, dissatisfaction with dentures and a reduced ACHF with complete dentures were associated with a higher FI both cross-sectionally and prospectively.

RESUMEN Objetivo: Comparar la cantidad y características de las prótesis dentales removibles parciales y totales, en el servicio de odontología del Hospital Nacional de Geriatría y Gerontología, en el periodo de tiempo comprendido del 1 de enero 2005 al 31 de diciembre 2008, equivalentes a 326 expedientes. Se tomó la base de datos del servicio de odontología de consulta externa especializada de los pacientes atendidos de los años 2005 al 2008, en los cuales se entregaron un total de 2786 prótesis dentales removibles. Materiales y métodos: Con base en el dato anterior se seleccionó la muestra no aleatoria a conveniencia hasta alcanzar el tamaño de 599 prótesis entregadas, examinando 326 expedientes del periodo de enero del 2005 a diciembre del 2008, con un nivel de confianza de 99% y un error de muestreo de 0.0466. La recolección de datos se realizó por medio del programa Microsoft Excel donde se utilizó una tabla en la que se anotó el número de expediente, fecha de inicio y conclusión de prótesis, tipo de prótesis, cantidad y color de prótesis, edad, género y domicilio del paciente por distrito, cantón y provincia. El procesamiento se realizó por medio de estadística descriptiva utilizando cuadros y gráficos. Resultados: Se determinó que el mayor porcentaje de rango de edad de personas que solicitaron prótesis removibles fue de 62 a 65 años, independiente si eran prótesis totales o parciales, los pacientes que requirieron dos prótesis fueron 273 de 326, en su mayoría los pacientes solicitaron prótesis totales para un total de 372 de 599 prótesis entregadas. De la guía de color utilizada en el HRBC los colores más requeridos fueron los tonos claros blanco amarillentos que corresponde al número 62 y 65; de los expedientes analizados la mayoría de los pacientes residían en San José con un total de 200 pacientes. Se concluye que el mayor porcentaje de edentulismo que se presento es el edentulismo total con un 62%, la prótesis más utilizada es la prótesis total superior removible y en su mayoría los pacientes requieren dos prótesis, con respecto al color no es concluyente para este estudio debido a los datos no disponibles en los expedientes analizados.
ABSTRACT Objective: Compare the quantity and characteristics of partial and total removable dental prostheses, in the dentistry service of the National Hospital of Geriatrics and Gerontology, in the period from January 1, 2005 to December 31, 2008. The database of the specialized outpatient dentistry service of the patients treated from 2005 to 2008 was taken, in which a total of 2786 removable dentures were delivered. Materials and methods: Based on the previous data, the non-random sample was selected for convenience until reaching the size of 599 protheses of 326 files, with a confidence level of 99% and a sampling error of 0.0466. Data collection was carried out through the Microsoft Excel program where a table was used in which the file number, date of start and conclusion of the prosthesis, type of prosthesis, amount and color of prosthesis, age, gender and address were used of the patient by district, canton and province. The processing was carried out by means of descriptive statistics using tables and graphs. Results: It was determined that the highest percentage of the age range of people who requested removable prostheses was 62 to 65 years, the patients that required two prostheses were 273 of 326. In their majority, the patients requested total prostheses for a total of 372 of 599 prostheses delivered. Of the color guide used in the HRBC, the most requested colors were the light yellowish-white tones corresponding to the number 62 and 65; of the files analyzed, most of the patients resided in San José with a total of 200 patients. Conclusion: It is concluded that the highest percentage of edentulism that is presented is total edentulism with 62%, the most commonly used prosthesis is the removable upper total prosthesis and for the most part patients require two prostheses, with respect to color it is inconclusive for this study due to data not available in the analyzed files.

This study aimed to identify factors associated with the need for complete dentures in one dental arch or both, among the elderly population. The cross-sectional household study was conducted with a representative sample of elderly people (65 years or older) in the state of São Paulo, Brazil, in 2015. The dependent variable was the need for complete dentures (in one arch or both), and independent variables were socioeconomic and demographic conditions, social capital, self-perception of oral health and access to dental services. Simple and multinomial logistic regression models tested effect measures (p < 0.05). A total of 5,948 elderly people participated. Results indicated that those with greater chances of needing a complete denture in one arch were male (OR = 1.54; CI95%:1.04-2.29), with fewer household goods (OR = 2.25; CI95%:1.50-3.38), lower monthly household income: R$501-1500 (OR = 3.44; CI95%:1.27-9.35), R$1501-2500 (OR = 4.11; CI95%:1.50-11.27), R$2501-4500 (OR = 2.76; CI95%:1.10-6.95), self-reported need for a complete denture (OR = 4.75; CI95%:3.08-7.35), ≥3 years since last dental appointment (OR = 1.80; CI95%:1.06-3.05), and dissatisfaction with last dental appointment (OR = 1.80; CI95%:1.06-3.05). There were more chances of the need for complete dentures in both arches among older elders (OR = 1.44; CI95%:1.06-1.88), with lower monthly household income: R$ < 501 (OR = 4.45; CI95%:1.71-11.60), R$501-1500 (OR = 4.01; CI95%:2.14-7.51), R$1501-2500 (OR = 2.95; CI95%:1.64-5.32), < 3 years of education (OR = 1.45; CI95%:1.13-1.85), feeling unhappy (OR = 2.74; CI95%:1.35-5.57), self-reported need for a complete denture (OR = 8.48; CI95%:5.75-12.50), dissatisfaction with their mouth (OR = 2.38; CI95%:1.64-3.46), ≥3 years since last dental appointment (OR = 4.28; CI95%:2.85-6.43), and dissatisfaction with last dental appointment (OR = 4.28; CI95%:2.85-6.43). The several dimensions of the determinants of the need for a complete denture reflect the influence of both demographic and socioeconomic aspects, social capital, self-perception of oral health and access to dental services.

OBJECTIVE: To develop a budgetary impact analysis regarding the possibility of offering complete upper and lower dentures to an eligible population of elderly people (above 65 years) in the São Paulo state, Brazil. METHODS: The proportion of eligible population was calculated by assessing the prevalence of edentulous (upper and lower arch) and by defining the eligible group (public health system users). The budgetary impact analysis was designed under the following scenario: 5-year time horizon (2018-2022), prospect of municipal expenses with prostheses, and additional progressive incorporation of technology (upper and lower dentures) at an annual rate of 10%, 15%, 20%, 25%, and 30%. Sensibility analysis was performed in 3 different situations (reference, more pessimistic, and more optimistic) based on the calculation of spending through assessed demand and epidemiological demand. RESULTS: The municipal cost for each denture, already discounted the value transferred by the union for this procedure, was R$50.97. The incremental impact on the budget measured by the epidemiological demand relative to assessed demand was approximately R$59 141 510 over 5 years, meaning an impact of 0.08% (0.01% more optimistic; 0.13% more pessimistic) of the "medium and high complexity care" budget and 0.09% (0.03%-0.14%) of the primary care budget. CONCLUSION: The budgetary impact of increasing the oral rehabilitation with complete dentures for elderly population in the São Paulo state is low relative to the expenses with primary or specialized care budgets. In addition, incorporation of denture rehabilitation would be feasible, according to the financial availability and priorities of each municipality.

Introdução: Perda dentária constitui indicador prévio de envelhecimento acelerado, em particular nos idosos institucionalizados, sendo preferencialmente tratada com reabilitações protéticas. Uma das manifestações patológicas do envelhecer que compartilha características com perdas dentárias é a síndrome da fragilidade. Objetivo: Avaliar relação entre uso de prótese total e síndrome da fragilidade em idosos institucionalizados. Métodos: Estudo transversal, com 69 idosos institucionalizados, realizado em João Pessoa-PB, Brasil. Foram utilizados formulário para avaliar saúde bucal, condição protética e testes específicos para variáveis do fenótipo de fragilidade. Na análise estatística foram aplicados testes t-Student e Qui-Quadrado. Resultados: A amostra caracterizou-se pelo predomínio de frágeis (49,3%) e usuários de prótese total (50,7%). Os pré-frágeis e frágeis apresentaram maior prevalência de edentulismo e de uso de prótese total (56,3% e 39,4%, respectivamente). Contudo, não foram encontradas diferenças significativas entre os grupos (p = 0,05). Conclusão: É sugerido que o uso de prótese total não influencia a fragilidade em idosos institucionalizados. (AU)
Background: Tooth loss is an early indicator of accelerated aging, in institutionalized elderly in particular, being preferentially treated with prosthetics rehabilitation. One of the pathological displays of to age, that share characteristics with tooth loss, is the frailty syndrome. Objective: Evaluate relationship between total prosthesis use, and frailty syndrome in institutionalized elderly. Methods: Cross-sectional study of 69 institutionalized elderly in the city of João Pessoa, Brazil. A form to assess oral, and dental health data, and specific tests for frailty phenotype variables were used t Student's and chi-square test was applied in statistical analysis. Results: The sample was characterized as predominantly denture complete use (50,7%), and frail (49,3%). Pre-frail, and frail exhibited highest prevalence of edentulous, and complete denture use (56,3% e 39,4%, respectively). However, no significant differences were found between groups (p = 0,05). Conclusion: It is suggested that complete denture use wasn't related to frailty in institutionalized elderly. (AU)

O objetivo desse estudo foi desenvolver uma infraestrutura de prótese total fixa sobre implantes em impressora 3D, elaborada em conjunto com uma guia cirúrgica digital, também impressa, diminuindo o número de sessões e substituindo a necessidade de moldagem logo após o procedimento cirúrgico. Para isso um paciente, sexo masculino, 60 anos de idade e apresentando apenas a presença do elemento dental 36 na arcada inferior, foi convidado a participar do estudo após leitura e assinatura de Termo de Consentimento Livre e Esclarecido. Foi realizada moldagem da arcada superior e inferior do paciente com alginato para confecção do modelo de estudo com gesso pedra especial. Os modelos foram escaneados com a utilização de scanner Xcad 3D, para a realização do planejamento cirúrgico e protético. A partir dos exames tomográficos foram obtidos os arquivos DICOM. Estes arquivos foram utilizados para o inicio do planejamento digital, sendo incluídos no software para planejamento específico. Foi realizado o planejamento virtual com o auxílio do software, sendo: instalação de 4 implantes do tipo hexágono externo de 13mm por 3,75mm cada, o que gerou automaticamente pelo software a guia cirúrgica para instalação dos mesmos. A mesma foi impressa com o uso de uma impressora 3D de polímeros. A guia cirúrgica continha quatro orifícios para instalação dos implantes planejados, permitindo também a instalação de a ut nts. p s a olo açao dos implantes, foram instalados pilares cônicos de 4,1mm de diâmetro com 3mm de altura de trans-mucoso. A barra protética final foi confeccionada com o mesmo padrão de conexão morse existente na guia cirúrgica, a partir de impressão 3D em material calcinável e fundido posteriormente. Dessa forma foi possível posicionar a barra sobre os abutments para confirmar e validar sua passividade. A técnica de impressão de barra protética guiada por uma guia cirúrgica também impressa e planejada em um software de planejamento odontológico específico demonstrou, em teste e análise em modelo de estudo, alta eficácia no aspecto de posicionamento 3D, adaptação da barra protética sobre os implantes e acertividade no que diz respeito a planejamento virtual / posição real dos implantes(AU)
Digital planning and preparation of guides and prosthesis with the help of 3D printers is a reality on a daily basis, but in this study, we look for Develop a fully digitized and software-driven process to design and execute polymer and titanium printed guides and prostheses. Those Printed parts would already be structural parts of the final prosthesis, Cases of total fixed prostheses. With this we could exclude laboratory phases of the process of prosthetic preparation, optimizing time, cost and reducing everyday problems that affect clinicians in such processes as repetitions, lack of adaptation of the prosthesis structure, teeth assembly, among others. Titanium printing of such a final structure would allow an immediate installation, in Immediate loading surgeries, of the final prosthesis with the best possible adaptation, Enabling the clinician to execute cases of extreme challenges Without the need for castings and welds, thus Aesthetics to the patient reducing treatment time with assertiveness(AU)

Antecedentes: El síndrome de Sjögren es una enfermedad autoinmune que empieza a manifestarse hacia los 45 años de edad y cuya incidencia aumenta con la edad. La sintomatología en la cavidad oral se caracteriza por boca seca o xerostomía. Gran cantidad de pacientes que la padecen son portadores de prótesis totales debido a la pérdida dental en edades avanzadas. Objetivo: Describir el caso de un paciente con síndrome de Sjögren a quien se le elaboró una prótesis con reservorio salival para disminuir síntomas orales. Métodos: Se realizaron ensayos de laboratorio para elaborar los reservorios buscando resistencia estructural de la prótesis; facilidad de colocación y retiro de las tapas de los reservorios para permitir la limpieza de los depósitos; estética y que contuvieran la mayor cantidad posible de saliva artificial. Los diseños se probaron en el paciente. Resultados: Después de realizar ensayos de prueba de la prótesis en ambos maxilares, el paciente comentó sobre la facilidad de retiro de las tapas, ausencia de nauseas, fonética normal, higiene adecuada, comodidad, solución parcial al problema de xerostomía y duración aproximada de tres horas una vez llenos los reservorios. Conclusión: Los prototipos finales proporcionaron mejores condiciones de los reservorios y aumentaron la cantidad de saliva. Se recomienda realizar estudios clínicos controlados para confirmar los hallazgos de este caso.
Background: Sjögren's syndrome is an autoimmune disease that manifests after the age of 45 years and whose incidence increases with age. Symptoms in the oral cavity includes dry mouth or xerostomia. Large number of Sjögren's patients wear complete dentures due to tooth loss at advanced ages. Objective: To describe the case of a Sjögren's patient for whom dentures with salivary reservoirs were made to reduce oral symptoms. Methods: Lab tests were conducted to find an optimum denture design with reservoirs. Requirements included: structural resistance, easy placement and removal of reservoir caps to allow cleaning, good esthetics, and containing the greatest amount of artificial saliva. Models were tried in the patient. Results: Several models were tried for both jaws. At the end, the patient reported about easiness to remove caps, absence of nausea, normal phonetics, adequate hygiene, comfort, and partial solution to the problem of xerostomia with an approximate duration of three hours once the reservoir was full. Conclusion: Final prototypes provided the best characteristics of reservoirs and stored the highest amounts of saliva. It is important to conduct clinical controlled trials to confirm the findings of this case.

OBJECTIVE: To estimate the prevalence of self-reported gingival and periodontal conditions and their association with smoking, oral hygiene, indigenous origin, diabetes and location (urban or rural) in indigenous and non-indigenous adults in Chiapas, Mexico. METHODS: A cross-sectional study of 1,749 persons, ≥20 years of age, living in four rural and four urban marginal localities in Comitán (Chiapas, México). The variables investigated were: age; sex; indigenous origin; oral hygiene; halitosis; chewing ability; gingival conditions; periodontitis; smoking; alcoholism; diabetes; and location. Bivariate analysis and a logistic regression model were used to identify the association of periodontitis with the independent variables. RESULTS: In total, 762 (43.6%) indigenous and 987 (56.4%) non-indigenous persons were interviewed. Their mean age was 41 ± 14 years, 66.7% were women and 43.8% lived in rural locations. Gingival problems were reported by 68.5% and periodontitis by 8.7%. In total, 17.9% had used dental services during the previous year, 28.7% wore a removable partial or a complete dental prosthesis, 63.7% had lost at least one tooth, the prevalence of diabetes was 9.2% and the prevalence of smoking was 12.2%. The logistic regression model showed that age, diabetes and the interaction between rural location and indigenous origin were associated with the presence of periodontitis. CONCLUSIONS: Indigenous people living in rural areas are more likely to have periodontitis. It is necessary to promote oral health practices in indigenous and marginalised populations with a focus on community-oriented primary care.

Introdução: As próteses totais visam conservar a função do sistema estomatognático do paciente totalmente edêntulo. Porém, na mucosa bucal podem aparecer manifestações cuja principal causa são as próteses totais mal adaptadas. Objetivo: o presente estudo objetiva investigar a proliferação tecidual das lesões causadas por próteses totais removíveis através do método de impregnação pela prata (AgNOR), com isso facilitando o tratamento e a determinação do prognóstico das lesões a serem estudadas. Metodologia: foram selecionados todos os casos das lesões bucais mais comumente associadas à utilização de próteses totais registradas no Serviço de Diagnóstico Histopatológico do ICBUPF nos anos de 2012 e 2013, tendo sido encontrados 5 casos de granuloma piogênico, 5 casos de hiperplasia de fundo de sulco, 5 casos de fibroma de irritação e 2 casos de fibroma ossificante periférico. Os cortes histopatológicos das lesões foram impregnados pela prata (método AgNOR), tendo sido obtido, com auxílio do programa Image Tool®, o número de NORs de 100 células de cada caso, resultando numa média de NORs em cada grupo de lesões. Resultados: os resultados obtidos foram tabulados em planilha eletrônica e a comparação do número médio de NORs de cada grupo foi realizado por meio do teste estatístico ANOVA, 5% de significância. Resultados: o grupo das hiperplasias de fundo de sulco mostrou média de 2,41 NORs por núcleo, o grupo dos granulo mas piogênicos mostrou 2,44, o fibroma de irritação 2,22, e o fibroma ossificante periférico mostrou média de 1,89 NORs por núcleo celular, diferindo estatisticamente esta lesão das anteriormente mencionadas (p = 0,002). Conclusão: o fibroma ossificante periférico mostrou ser a lesão causada por prótese total removível com a menor atividade proliferativa celular. Tal estudo precisa ser complementado por futuros estudos clínicos.
Introduction: the total dentures are aimed at preserving the function of the stomatognathic system of the fully edentulous patient. However, in the oral mucosa may appear manifestations whose main cause are the totally unsuitable dentures. Objective: this study aims to investigate the proliferation of tissue lesions caused by removable dentures by impregnation method for silver (AgNOR), thereby facilitating the treatment and determining the prognosis of the lesions to be studied. Methodology: we selected all cases of oral lesions most commonly associated with the use of dentures recorded in Histopathological Diagnostic Service ICB-UPF in the years 2012 and 2013, having been found 5 cases of pyogenic granuloma, 5 cases of hyperplasia, 5 cases of irritation fibroma and 2 cases of peripheral ossifying fibroma. Histopathological lesions cuts were impregnated by silver (AgNOR method), having been obtained with the aid of the program Image Tool®, the number of NOR cells 100 in each case, resulting in an average NORs in every group of lesions. Results: the results were tabulated in a spreadsheet and comparing the average number of NORs of each group was conducted through ANOVA, 5% significance level. Results: The group of hyperplasias showed average of 2.41 NORs per nucleus, the group of pyogenic granulomas showed 2.44, the irritation fibroma 2.22, and peripheral ossifying fibroma showed average of 1.89 NORs for cell nucleus, differing significantly from that of the aforementioned lesions (p = 0.002). Conclusion: the peripheral ossifying fibroma proved the injury caused by removable dentures with lower cell proliferative activity. This study needs to be complemented by future clinical studies.

BACKGROUND: To describe the prevalence of missing teeth, use of bridges and dentures and unmet dental needs among those aged 60 years and above. The associations of these conditions with socio-demographics, type 2 diabetes mellitus and depression were also studied. The work was carried out in 7 Latin American and Caribbean (LAC) cities in 1999-2000. METHODS: A secondary analysis was conducted on the Survey of Health and Well-Being of Elders (SABE) dataset. The 7 cities were Buenos Aires, Bridgetown, São Paulo, Santiago, Havana, Mexico City and Montevideo. This survey did not employ any oral examinations. Descriptive statistics, chi-square and regression analysis were used to test for associations. RESULTS: Data for 10 902 persons were analyzed. Females made up 62% of the population. Across the SABE population, between 93.7% (Mexico City) to 99.9% (Santiago) reported missing teeth, with an average of 97.5%. Of those with missing teeth, between 55.1% (Mexico City) and 82.4% (São Paulo) reported having bridges or dentures, with an average of 70.1% across all SABE cities. The proportion of the SABE population with 'unmet dental needs' ranged from 85.8% (Santiago) to 98.4% (Havana), with an average of 94.5%. Bridgetown, São Paulo and Mexico City demonstrated a statistically significant association between aging and tooth loss. Generally a greater proportion of females (97.6%) reported tooth loss compared with males (96.8%), but in only São Paulo and Montevideo was there a statistically significant association between sex and tooth loss. Generally those with higher education reported less tooth loss, primary education (97.6% had tooth loss), secondary (96.8%) and tertiary (94.7%). All the SABE cities except Buenos Aires demonstrated a statistically significant association between tooth loss and education. CONCLUSIONS: The prevalence of missing teeth, use of bridges and dentures and unmet dental needs were high in the SABE cities in 1999-2000. In general across the SABE cities, the elderly with the most missing teeth were less educated or less likely to be a professional. They tended to be not working and were receiving a pension. Additionally they were less likely to report their health as 'excellent', were diabetic and were more likely to give responses suggestive of depression.

Since prognostic indicators are likely to take on increasingimportance as a diagnostic tool for selection of patients forimplant provision, this study investigated the influence of theshape and resiliency of the mandibular alveolar ridge on theretention and stability of conventional complete dentures. Ninety-three edentulous patients wearing both maxillary andmandibular conventional complete dentures composed the sample.Data were collected regarding shape and resiliencyof themandibular residual ridge. Dentures were assessed for retentionand stability using an objective and reproducible tool.The associationsbetween the clinical characteristics of the mandibularalveolar ridge and denture retention and stability were analyzedusing chi-square and Fisher exact tests (α = 0.05). A significantassociation between ridge shape and denture stability (p < 0.05)was found, while ridge resiliency was significantly associated todenture retention (p < 0.001). Based on the results, mandibularridge shape and resiliency influenced the retention and stabilityof conventional complete dentures...

OBJECTIVE: The purpose of this study was to investigate the prevalence of temporomandibular disorders (TMD) in denture wearers and the association between prosthetic factors and this condition. BACKGROUND: There is no consensus about the relationship between prosthetic factors and TMD among denture wearers. MATERIALS AND METHODS: The sample was composed of 92 patients wearing both maxillary and mandibular complete dentures. The Research Diagnostic Criteria for TMD (RDC/TMD) were adopted for patient examination. Objective evaluation of denture quality was determined by analysis of retention and stability of mandibular denture, interocclusal distance, articulation and occlusion. Association between denture quality and TMD diagnosis was analysed using chi-square and Fisher's exact tests. RESULTS: 37.4% of the patients presented TMD. Denture quality was not significantly associated with the presence of TMD: mandibular retention (p = 0.466); mandibular stability (p = 0.466); interocclusal distance (p = 0.328); centric relation (p = 0.175); and balanced occlusion (p = 0.56). CONCLUSION: Within the scope of this case-controlled cross-sectional study, no robust association between prosthetic factors and TMD was found.

El objetivo de este estudio fue comparar las medidas de fuerza máxima de mordida (MBF) en pacientes desdentados adultos mayores indígenas (Mapuches) y no indígenas, en el momento de recibir sus prótesis totales y un mes posterior a la inserción.Una muestra de 100 sujetos adultos mayores fue dividida en dos grupos: 50 indígenas y 50 no indígenas, cada uno de ellos con 25 pacientes de sexo femenino y 25 masculino. Todos los individuos estudiados eran completamente edéntulos, quienesrecibieron prótesis removibles totales nuevas tanto superior como inferior. Las medidas fueron realizadas en el momento de la inserción de ambas prótesis y posterior a un mes de uso. Seles solicitó a los sujetos que realizaran un esfuerzo máximo con tres mordidas por lado en máxima intercuspidación, con un tiempo de descanso de 2 minutos entre cada medición. El análisisestadístico fue realizado por medio del test t-Student´s. Los valores de fuerza máxima observados en los sujetos indígenas fueron significativamente mayores que en los individuos no indígenas. Además, los valores de fuerza posterior al mes de uso dela prótesis nueva fueron significativamente mas altos que losobtenidos al momento de la inserción de la prótesis. Por otro lado, no se identificaron diferencias significativas en los valores entre los lados izquierdo y derecho. Así, los pacientes indígenasmostraron valores mayores de fuerza masticatoria máxima. También, se pudo observar que los pacientes sufrieron un proceso de adaptación a las prótesis nuevas, en los cuales la fuerza máximamasticatoria posterior a un mes aumentó considerablemente...

OBJECTIVE: The prevalence of wearing and fracture of complete dentures was evaluated among edentulous patients treated in two dental schools in Brazil. BACKGROUND: Acceptance and wearing of complete dentures are related to adaptive behaviour of edentulous patients. However, one reason that could interfere with the wearing dentures is their potential to fracture, which is still a common complication in denture rehabilitation practice. MATERIAL AND METHODS: Two hundred and twenty-four edentulous patients rehabilitated with complete dentures from 2000 to 2005 in Araçatuba and Araraquara Dental School, University of State of São Paulo, were assessed in 2006 and 2007 to answer a questionnaire about wearing and fracture of their dentures. Statistical analysis were performed using Epi Info software and chi-squared test to compare maxillary and mandibular data (α = 0.05). RESULTS: Almost 26% of the patients did not wear their dentures, and among the remainder, the majority wore the maxillary denture. About 30% of the dentures were fractured, with higher prevalence in the maxillary arch (p = 0.003). CONCLUSIONS: Discontinuation of wearing dentures was quite high, especially considering the treatment which was carried out in university clinics. Prevalence of fractures was also high, greater for the maxillary denture, and was one of the main reasons for non-wearing of complete dentures.

BACKGROUND: Complete tooth loss among the elderly is still frequent in developing countries and the incidence of temporomandibular disorders (TMD) is a common finding in complete denture wearers. OBJECTIVES: The aim of this study was to evaluate the prevalence of temporomandibular disorders (TMD) in a population of complete denture wearers. MATERIALS AND METHODS: The data were collected by four examiners for the diagnosis of use and need for complete dentures followed by the World Health Organization standards and interviews for TMD signs and symptoms evaluation. Exploratory variables included demographic, socio-economic status and TMD prevalence. RESULTS: The prevalence of TMD among denture wearers was 55.12%. Chi-squared test showed no statistical difference between subjects with or without TMD for gender, geographical location and skin colour (p < 0.05). The number of subjects with TMD increased as the period of complete denture wear increased, although no statistical difference between groups were found (p < 0.05). CONCLUSIONS: There is a need of educational programmes aiming at the importance of health care and periodical change of a complete denture, and strategies with a preventive approach to quality general dental care.

The aim of the study was to determine whether there is any relationship between the presence of removable dentures and squamous cell carcinoma of the anterior two thirds of the tongue in a Portuguese population. A retrospective cross-sectional study was conducted on patients with a biopsy-proven diagnosis of squamous cell carcinoma of the tongue, who were seen and treated at the Department of Head and Neck Surgery of the Portuguese Institute of Oncology 'Francisco Gentil', Lisbon, Portugal, during a 3-year period. Several factors were examined: gender, use of removable dentures, age, location of the lesion, and alcohol and tobacco consumption. One hundred and six cases were selected from the initial 151 cases, with a male:female ratio of 3:1 and the lateral borders being the most commonly affected site. The prevalence in both genders was between the sixth and seventh decade of life. Men were more likely to consume alcohol and tobacco than women, and no relationship was observed between denture use and presence of carcinoma of the tongue. In light of the data obtained, it may be considered that female use of a denture plays an important role, but it cannot be identified as a remarkable etiologic factor.

OBJECTIVE: The aim of this study was to evaluate the overnight wearing and cleaning habits of complete denture wearers. BACKGROUND: Successful complete denture treatment can be achieved when the patients are motivated and aware of appropriate denture wear and hygiene. MATERIALS AND METHODS: A sample of 224 complete denture wearers (162 women) aged 37-89 years was studied. Inclusion criteria comprised edentulous subjects who had received their new complete dentures between 2000 and 2005 in the Dental Clinic of the Araçatuba and Araraquara Dental School, São Paulo State University. Ethical approval was sought and granted. Subjects were interviewed using questions related to overnight denture wearing and denture cleaning habits. Possible statistical relationships among some of items were analysed by the chi-square test at 5% significance level. RESULTS: Of the patients, 55.8% removed their dentures during the overnight period and 88% did this every day. Among them, 66.4% removed both dentures. Most of the patients used brushing with toothpaste (105 patients - 46.87%) as a cleaning method. More than a half of the subjects (63.4%) showed biofilm and calculus on their dentures. CONCLUSION: The patients need instructions and motivation concerning denture hygienic and denture removal overnight.

The aim of this study was to identify factors influencing edentulous patients' preferences for treatment using conventional or implant dentures (ID). A consecutive sample of 112 patients was selected in a university facility. All patients responded to a questionnaire concerning preferences about treatment and factors influencing preferences for conventional complete dentures (CD), implant-retained overdentures (IRO) and fixed implant-supported prostheses (FISP). Subsequently, a set of 21 questions was presented, and patients were requested to rate the importance of various potential reasons influencing their choice of treatment. Preference for CD was more prevalent for maxilla (52·7%) and mandible (41·1%). Fixed implant-supported prostheses and IRO were preferred for the mandible (FISP=37·5%; IRO=21·4%) rather than maxilla (FISP=27·7%; IRO=19·6%). The most preferred treatment option among the subjects when evaluating both arches was the implant-supported fixed or removable prosthesis (FISP/IRO). A preference for combined upper and lower CD was also commonly reported (39·3%). Factor analysis identified six components that accounted for 72·2% of the total variance: (i) psychosocial benefits, (ii) functional performance, (iii) technical and financial concerns, (iv) post-insertion complaints, (v) removability and (vi) longevity. Technical and financial concerns (cost, complexity, surgery risks and duration of treatment) were more relevant for those who preferred ID (P<0·001). With the exception of post-insertion complaints, all mean scores of component factor loadings were positive for ID. Conventional complete dentures are associated with lower expected outcomes by patients, and cost-related issues are the major factors associated with the preferences for implant treatment of edentulous patients.
