Associação entre o uso de prótese dentária total e o tipo de serviço odontológico utilizado entre idosos edêntulos totais / Association between the use of total dental prosthesis (denture) and the type of oral health care service used by toothless elderly individuals

Resumo A reabilitação protética foi prevista pela política nacional de saúde bucal em função da alta prevalência de perda de todos os dentes e do baixo uso de prótese dentária entre idosos. Há necessidade de se avaliar o impacto dessa política de reabilitação. Portanto, objetivou-se investigar se o tipo de serviço odontológico utilizado foi um dos fatores associados ao uso de prótese dentária total entre idosos. Trata-se de um estudo transversal conduzido em uma amostra probabilística de idosos (60 anos ou mais) residentes na zona urbana de um município brasileiro de pequeno porte populacional por examinadores calibrados. Realizaram-se análises descritiva, bivariada e múltipla (Regressão logística - odds ratio - OR). Participaram 287 idosos, destes, 186 (64,8%) faziam uso de prótese dentária total. O uso de prótese dentária total foi associado a maiores chances de uso de serviços odontológicos supletivos ou particulares (OR = 4,19; p < 0,001) e a presença de lesão no palato (OR = 7,52; p = 0,002) e, também, a menores chances em idades maiores ou iguais a 73 anos (OR = 0,52; p = 0,023) e entre os com comprometimento na dimensão incapacidade física do OHIP-14 (OR = 0,20; p = 0,002). O uso de prótese dentária total foi associado ao tipo de serviço odontológico entre idosos, sendo maior o uso entre usuários dos serviços supletivos ou particulares.

Abstract Oral rehabilitation with dental prosthesis was mandated by national oral health policy in Brazil, due to the high prevalence of total teeth loss and low use of dental prosthesis among the elderly. There is a pressing need to assess the impact of this rehabilitation policy. An attempt was therefore made to investigate if the dental service used was one of the factors associated with the use of total dental prosthesis among the elderly. To achieve this, a cross-sectional study using a probabilistic sample of elderly (60 years and above) urban-area residents of a small city was conducted by qualified examiners. Descriptive, bivariate and multiple (logistic regression/odds ratio - OR) analyses were conducted on 287 elderly people, of which 186 (64.8%) used dental prosthesis. The use of total dental prosthesis was associated with a higher probability of being attended by private dental services (OR = 4.19; p < 0.001) and the presence of lesions on the palate (OR = 7.52; p = 0.002). Conversely, it was associated with lower probability in ages greater than or equal to 73 years (OR = 0.52; p = 0.023) and among those with impairment of OHIP-14 (OR = 0.20; p = 0.002) in the physical disability dimension. The use of total dental prosthesis was associated with the type of dental service used by the elderly, it being greater among private service users.

Exploratory and confirmatory factorial analysis of the OHIP-Edent instrument

Abstract Several instruments have been used to measure oral health-related quality of life (OHRQoL). The Oral Health Impact Profile (OHIP) questionnaire was based on the concept that sequential events related to oral diseases can cause discomfort, functional limitations and consequently, result in dysfunctions and even disabilities. There are few studies in the literature that structurally analyze the instruments to verify whether they measure the requirements to which they were designed to. The objective of the study was to evaluate the internal structure of the OHIP-Edent questionnaire. The OHIP-Edent was administered to 54 edentulous patients' wearers of conventional complete dentures. For structural analysis, an exploratory factorial analysis (EFA) was carried out. After determining the internal consistency of the model (Cronbach's alpha = 0.88), the fit was checked using the root mean square error approach (value 0.04), the comparative fit index (value 0.982) and the Tucker-Lewis index (value 0.976). After analysis of the 19 questions and the seven domains proposed in the OHIP-Edent questionnaire, the hypothetical factorial model showed three dimensions denominated "Physical Impact", "Psychological Impact" and "Social Impact". In this sample of conventional complete denture wearers, the OHIP-Edent seems adequate to measure the "Physical Impact", "Psychological Impact", and "Social Impact" of the OHRQoL. The confirmatory factorial analysis confirmed the model and, through adjustment indexes, it was verified that the three dimensions have convergence and consistence adequate in order to characterize the OHRQoL construct with validity.

Quality of life and mastication in denture wearers and cleft lip and palate adults

Abstract The impact of oral rehabilitation on masticatory function and oral health-related quality of life (OHRQoL) may vary with the experience of the individual with tissue loss. Our hypothesis is that patient-centered outcomes vary among adults who have experienced large defects in the maxilla due to congenital or acquired conditions even after oral rehabilitation to restore aesthetics and function. This study compared OHRQoL, perceived masticatory ability, maximum bite force (MBF), and symptoms of pain and depression among subjects with acquired (edentulous maxilla) and congenital (cleft lip and palate) loss of oral tissues in the maxilla after dental treatment. A gender-matched sample (n = 60) of cleft lip and palate (CLP), maxillary denture wearers (DENT) and controls (CONT) was recruited. OHRQoL was assessed using OHIP-14. Chewing was evaluated through a masticatory ability questionnaire and by MBF. The RDC/TMD Axis II questionnaire was used to assess symptoms of pain and depression. Data were analyzed by Fisher's test, Kruskal Wallis test, and Spearman correlation coefficients. CLP showed higher OHIP-14 and depression scores than DENT and CONT (p < 0.05). Sub-analysis by OHIP-14 items (%FOVO) showed higher prevalence of psychological impact for CLP and of functional impacts for DENT. The number of foods difficult to chew, of food textures difficult to chew, and avoided foods were similar between CLP and DENT. OHIP-14, MBF, and depression scores showed significant correlation (p < 0.05). The results suggest that adults with treated CLP or maxillary DENT have chewing impairment and lower MBF than healthy subjects, with different psychological and functional impacts.

Perception of caregivers on health and oral hygiene care of institutionalized impaired elderly / Percepción de cuidadores sobre salud y cuidados de higiene oral de ancianos discapacitados institucionalizados

This study assessed the perception of caregivers on oral health of institutionalized impaired elderly, and the care provided for them in oral hygiene and prosthetic rehabilitation. A descriptive observational study was developed with caregivers of 32 institutionalized impaired elderly, in the state of Sergipe, Brazil. Data collection was performed by interviewing the caregivers, researching records of the Institution, and by clinical examination of the oral cavity of the elderly during a period between the months of March and May, 2013. Data were analyzed by descriptive statistics of absolute frequency (n) and relative frequency (%). All of the elderly presented partial (50 %) or total (50 %) tooth losses, and only 28.1 % wore removable denture. The prosthetic devices and remaining teeth of the elderly were cleaned with only toothbrush and toothpaste (100 %), with different daily frequencies among caregivers and no dentist instruction. The majority of caregivers was satisfied with the oral hygiene of the elderly (75 %) and the oral hygiene method (96.9 %) used, and showed no interest in learning new methods (81.3 %). The caregivers have an inadequate perception on oral health of the elderly population investigated, and oral hygiene care provided to the elderly is precarious.

Este estudio analizó la percepción de cuidadores sobre la salud oral de ancianos discapacitados asilados y los cuidados entregados en la higienización oral y frente a la rehabilitación protética. Se realizó un estudio observacional descriptivo, por medio de entrevistas con los respectivos cuidadores de los 32 ancianos seleccionados, institucionalizados en el Estado de Sergipe, Brasil. Todos los ancianos presentaban pérdidas dentales parciales (un 50 %) o totales (un 50 %) y solo el 28,1 % hacía uso de prótesis dentaria removible. Los aparatos protéticos y dientes remanecientes de los ancianos se higienizaban solo con cepillo y crema dental (un 100 %), con frecuencias diarias divergentes entre los cuidadores, sin la orientación de un dentista. La mayoría de los cuidadores se mostró satisfechos con la salud oral del anciano (un 75 %) y (un 96,9 %) con el método de higiene oral que utilizaban, y no expresaron interés en conocer nuevos métodos (un 81,3 %). Se concluyó que los cuidadores tienen una percepción inadecuada sobre la salud oral de la población de ancianos investigada y que los cuidados de higiene oral entregados a los ancianos son precarios.

Implant-Supported Removable Partial Denture Improves the Quality of Life of Patients with Extreme Tooth Loss

Abstract: This study aimed to evaluate oral health-related quality of life (OHRQoL) in partially dentate subjects, presenting extreme tooth loss in posterior region with missing post-canines, comparing the use of conventional removable partial dentures (RPDs) and implant-supported RPDs. OHRQoL was measured using the Brazilian version of the Oral Health Impact Profile. Twelve subjects presenting maxillary total and mandibular Kennedy Class I edentulism (mean age 62.6±7.8 years) first received complete maxillary dentures and conventional mandibular free-end RPDs. After two months, the subjects had their OHRQoL assessed. Osseointegrated implants were inserted bilaterally in the mandibular first molar regions, and after four months ball abutments were placed to support the free-end RPD. Two months later, the patients had their OHRQoL reassessed. Wilcoxon signed-rank test was used to evaluate differences in OHRQoL (α=0.05). Results showed improvement in all OHIP-49 domains (p<0.05) after associating implants to the RPD. The mandibular implant-supported free-end RPD significantly improved OHRQoL.

Resumo: Este estudo avaliou a qualidade de vida relacionada à saúde bucal (QVRSB) em indivíduos parcialmente dentados, apresentando perda extrema de dentes na região posterior com ausência de dentes pós-caninos, comparando a reabilitação por meio de próteses parciais removíveis convencionais (PPRs) e PPRs implanto-suportadas. A QVRSB foi mensurada utilizando a versão brasileira do Oral Health Impact Profile (OHIP-49). Doze indivíduos apresentando edentulismo total maxilar e Classe I de Kennedy mandibular (idade média 62,6±7,8 anos) receberam primeiramente próteses totais maxilares e PPRs mandibulares convencionais de extremidade livre. Após dois meses de uso destas próteses, a QVRSB dos voluntários foi avaliada. Implantes osseointegrados foram bilateralmente instalados na região de primeiros molares inferiores e, após quatro meses, pilares do tipo bola foram instalados para suportar a extremidade livre da PPR. Após dois meses a QVRSB dos voluntários foi reavaliada. O teste pareado de Wilcoxon foi utilizado para avaliar as diferenças de QVRSB (α=0,05). Os resultados mostraram melhora em todos os domínios do OHIP-49 (p<0,05) após a associação dos implantes à PPR. PPRs de extremidade livre mandibulares implanto-suportadas melhorou significativamente a QVRSB.

Patient satisfaction concerning implant-supported prostheses: an observational study

The aim of this observational study was to assess the degree of patient satisfaction toward implant-supported prostheses. A questionnaire was used with two scales (one consisting of detailed adjectival and the other of numerical responses) regarding chewing, esthetics, speaking, comfort and overall satisfaction. The scales were administered to a sample of 147 patients treated with implants and prostheses. The data were submitted to the Kappa statistic and the Chi-square test to analyze the association between dependent and independent variables. High degrees of satisfaction (greater than 91%) were found for all categories evaluated, regardless of gender, age, number of implants or type of prosthesis. “Comfort” was associated significantly with the number of implants (p = 0.038), and “speaking” was associated significantly with the type of prosthesis (p = 0.029). Positive agreement was found between the scales for all categories evaluated, without statistically significant differences regarding respondent preference (p = 0.735). Patients treated with implant-supported prostheses were highly satisfied with the treatment.

Reabsorción ósea del reborde residual mandibular en desdentados totales / Bone resorption of the residual ridge in edentulous patients

Al perder los elementos dentarios, la remodelación ósea y mucosa produce una nueva estructura anatómica, el reborde residual. La reducción del reborde residual (RRR) es considerada como una enfermedad crónica, progresiva, irreversible, acumulativa en el tiempo, de etiología multifactorial. Objetivo: evaluar la pérdida del hueso alveolar en pacientes edéntulos usuarios y no de prótesis. Métodos: estudio en 115 pacientes, de 41 a 88 años, ambos sexos, edéntulos. Se realizó radiografía panorámica junto a historia clínica. Se cuantificó la altura ósea vertical, lado izquierdo y derecho, desde el borde inferior de la mandíbula al foramen mentoniano y desde el borde inferior mandibular al superior de la cresta. Se recabaron datos sobre edad, sexo, uso de prótesis dental y enfermedades sistémicas. Resultados: edad promedio 64,5 años; 71 por ciento usaba prótesis (71,91 por ciento mujeres y 28,09 por ciento varones). Hubo diferencias significativas en ambos sexos entre uso y no uso de prótesis y RRR en cada sector, derecho p=0,0173 e izquierdo p=0,0153. Los valores de RRR fueron 14,24 mm en varones y 18,03 mm en mujeres. La pérdida ósea fue mayor en mujeres posmenopáusicas y en hombres de más de 70 años. No se observaron asociaciones significativas con edad y con enfermedades sistémicas. Conclusión: la pérdida ósea aumenta en desdentados con la edad, por un factor fisiológico y pérdida de la función, el hueso no recibe fuerzas estimulantes. Las mujeres pierden más hueso que los hombres por factores hormonales propios u otros.
