ABSTRACT A population's utilization of dental services is an important parameter in oral health care planning, which has rarely been studied in China. The objectives of this report were to describe the dental service utilization pattern of middle-aged and elderly Chinese and to analyze the influence of selected variables on the use of dental services. A Guangdong Province population of 1,573 35- to 44-year-olds and 1,515 65- to 74-year-olds recruited from urban and rural communities was interviewed in their local dialect. It was found that 23% of the middle-aged and 24% of the elderly subjects had visited a dentist within the preceding year. The two most commonly cited reasons for not having seen a dentist for at least 3 years were: no perceived need, and no serious dental problems. Among subjects who had visited a dentist within 3 years, the 3 most commonly received treatments were: fillings, extractions, and dental prostheses. Furthermore, a logistic regression analysis showed that women, subjects who lived in urban areas, were better educated, were wealthier, and had better oral health knowledge were more likely to be a recent dental service user. In conclusion, dental service utilization among the adult Southern Chinese was found to be low, problem-driven, and influenced by some socio-economic factors.

    ABSTRACT: Southern China is the most prosperous part of China, but information useful for oral care planning is very limited. A large-scale epidemiological survey was conducted in 1996-97. The objectives of this report were to describe the coronal and root caries of the adult Southern Chinese and to analyze the influence of selected demographic and socio-economic factors on the disease pattern. A total sample of 1,573 35- to 44-year-olds and 1,515 65- to 74-year-olds from 8 urban and 8 rural survey sites in Guangdong Province participated in an oral health interview and underwent clinical examination. World Health Organization examination procedures and diagnostic criteria were used. The weighted mean DMFT scores of the middle-aged and the elderly subjects were 4.8 and 16.1, respectively. People living in rural areas had a higher DMFT score than those living in urban areas (4.9 vs. 4.3 in the 35- to 44-year-olds and 16.5 vs. 14.7 in the 65- to 74-year-olds). In both age groups, MT was the major component of the DMFT score. Analysis of covariance showed that women and those who were economically less well off had higher DMFT scores in both age groups. The weighted prevalence rates of decayed/filled roots were 12% and 37%, with a mean of 0.2 and 0.7 teeth affected, in the middle-aged and the elderly, respectively. In conclusion, socio-economic factors had a considerable effect on the dental caries status of adults in Southern China.

    ABSTRACT: ResumenObjetivosEl objetivo de nuestra investigación fue evaluar las desigualdades socio-económicas en el estado de salud oral y en la utilización de servicios odontológicos en la población de Cataluña.Métodos1. Estudio transversal de una cohorte de ancianos representativa de los individuos de la ciudad de Barcelona. El examen oral se realizó en 561 participantes y se registró el índice CAO. Además, se recogió información socio-económica y de utilización de los servicios odontológicos.2. Encuestas de Salud de Cataluña (ESCA) de 1994 (n = 15.000) y del 2002 (n = 8.400), La entrevista incluía información sobre utilización de servicios odontológicos en el último año, así como variables socio-económicas.Resultados1. El 42% de los ancianos de la ciudad de Barcelona eran desdentados totales. Entre los individuos dentados, el bajo número de dientes remanentes (14,9 en promedio), junto con un bajo número de dientes obturados (1,2 en promedio) y las necesidades no tratadas (2,2 dientes careados que necesitan obturación), indican que las extracciones han sido la principal forma de tratamiento para este grupo. El índice CAO en individuos dentados (media = 16,4) muestra una asociación significativa con la clase social (p = 0,001) después de ajustar por edad, género, cobertura sanitaria y utilización de servicios odontológicos.2. En Cataluña, sólo el 26,7% de las personas había utilizado servicios odontológicos durante el año previo en el año 1994., aumentando al 34,3% en el 2002. El género (masculino), la clase social y la educación fueron los factores que presentaron una asociación significativa con la no utilización de servicios odontológicos que se mantuvo estable entre ambos períodos. Mientras que las desigualdades según el tipo de cobertura sanitaria y para el grupo de ancianos se habían reducido sensiblemente en el 2002.ConclusionesLas desigualdades socio-económicas tanto en el estado de salud oral como en la utilización de servicios odontológicos indican un problema de acceso a este tipo de servicios. Este tipo de hallazgos son especialmente relevantes para países como España, con un Sistema Nacional de Salud para toda la población, de cobertura odontológica muy limitada.AbstractObjectivesThe aim of this study was to assess the socio-economic inequalities in dental health and dental care services utilization in Catalan population.Methods1. Cross-sectional study of an elders cohort representative of Barcelona city individuals. Oral examinations were performed in 561 participants according to the DMF Index, also socio-demographic and dental care services utilization details were collected.2. Catalan Health Interview Surveys (CHIS) of 1994 (n=15,000) and 2002 (n=8,400). The survey included information about dental care services utilization in the previous year, as well as socio-economic data.Results1. The 42% of elders in Barcelona city were edentate. In dentate individuals, the low number of remaining teeth (14,9 in average), the low number of filled teeth (1,2 in average) and the untreated needs (2,2 decayed teeth that need filling), showed that the tooth extraction had been the principal treatment for this group. DMF index in dentate individuals (mean = 16,4) showed a significant association with social class (p = 0,001) alter adjusting by age, gender, health insurance and dental care services utilization.2. In Catalonia, only 26.7 % of individuals had used dental care services during the previous year in 1994 and increased to 34.3 % in 2002. Gender (males), social class and education were the factors with a significant association with not utilization of dental care services, which were stable between both periods. While the inequalities according to health insurance status and older adults had decreased in 2002.ConclusionsThe socio-economic inequalities in the oral health status as well as dental care services use, indicate a problem of access to dental care services. This is of particular importance in countries like Spain, with a universal National Health System, but a dental care coverage very limited.
