Psychometric properties of the OHIP-14 and prevalence and severity of oral health impacts in a rural riverine population in Amazonas State, Brazil.

The objectives of this study were: (1) test the psychometric properties of OHIP-14 in a rural population; and (2) compare the oral health impacts in two riverine communities in the Brazilian Amazon that were living at different distances from an urban center. Data were obtained from a cross-sectional study in a consecutive sample (n = 126). The validity was assessed through the association of OHIP with clinical and subjective variables, which showed a more significant association with: pain, caries, need of extraction or endodontic treatment; than with tooth loss, periodontal disease or need of prostheses. The stability and internal consistency were good (ICC = 0.97; Cronbach's alpha = 0.89). The prevalence of oral impacts was greater in the community far from the urban center [70.3 (59.9-80.7)] than in the community closer to it [44.3 (30.7-57.7)], and in women [66.7 (56.0-77.3)] in comparison with men [49.1 (35.3-62.7)]. The OHIP-14 adapted to rural populations in Amazonas State was valid, reproducible, and consistent. There was high prevalence of impacts, especially for riverine communities that lived far from urban centers.

Os objetivos do trabalho foram: (1) testar as propriedades psicométricas do OHIP-14 em população rural e (2) comparar os impactos da saúde bucal em duas comunidades ribeirinhas amazônicas, com diferentes distâncias do centro urbano. Os dados foram obtidos de uma amostra consecutiva de pacientes (n = 126) em estudo de corte transversal. A validade do instrumento foi testada pela associação do OHIP com variáveis clínicas e subjetivas, sendo mais significativa para as variáveis: dor, cárie, necessidade de extração e de endodontia que para perda dentária, doença periodontal e necessidade de prótese. Estabilidade e consistência interna foram boas (CCI = 0,97; α Cronbach = 0,89). A prevalência de impactos foi maior na comunidade mais distante do centro urbano [70,3 (59,9-80,7)] que na mais próxima [44,3 (30,7-57,7)], e nas mulheres [66,7 (56,0-77,3)] comparadas aos homens [49,1 (35,3-62,7)]. O OHIP-14 adaptado às populações rurais da Amazônia foi válido, reproduzível e consistente. A prevalência dos impactos foi alta, especialmente para ribeirinhos que vivem distante dos centros urbanos.

[Provision and utilization of dental services in Amazonas State, Brazil: a case study in a riverine population in Coari municipality]. / Oferta e utilização de serviços de saúde bucal no Amazonas, Brasil: estudo de caso em população ribeirinha do Município de Coari.

This case study described the conditions in the provision and utilization of dental services in two riverine populations in the municipality (county) of Coari, Amazonas State, Brazil. Structured questionnaires were applied to individuals 18 years and older to measure dental services utilization rates. Semi-structured interviews were also conducted with key informants to characterize the provision of such services. Although the bivariate analysis did not detect any statistically significant differences, residents of the area farthest from the county seat had gone more time since their last dental visit and received less care from public health services and riverboat clinics. The qualitative analysis showed: no permanent dental services in the communities; sporadic services provided by riverboat clinics, with less frequent visits to the remotest community; high transportation cost for river-dwellers to seek treatment in the county seat; and dental treatment focused on pain control, mainly through tooth extraction. Limited access to dental services for riverine populations highlights the need to implement comprehensive health promotion measures and expand the availability of services.

Oferta e utilização de serviços de saúde bucal no Amazonas, Brasil: estudo de caso em população ribeirinha do Município de Coari / Provision and utilization of dental services in Amazonas State, Brazil: a case study in a riverine population in Coari Municipality

O presente estudo de caso teve o objetivo de descrever a oferta e utilização de serviços odontológicos em duas comunidades ribeirinhas do Município de Coari, Amazonas, Brasil. Para tanto, foram colhidos dados sobre freqüência de utilização de serviços de saúde bucal, por entrevistas estruturadas com indivíduos acima de 18 anos, e dados sobre oferta de serviços obtidos por entrevistas semi-estruturadas com informantes-chave. Nas análises bivariadas, embora sem diferença estatística, os indivíduos da comunidade mais distante da sede do município apresentaram maior tempo decorrido da última consulta, e menor proporção de atendimentos pelo serviço público e por barcos de saúde. A análise qualitativa das entrevistas revelou: ausência de serviço odontológico permanente nas comunidades; oferta esporádica através de barcos da saúde, com menor ocorrência dos serviços na comunidade mais distante; alto custo do deslocamento do ribeirinho à sede do município; e tratamento odontológico voltado para o controle da dor, basicamente se resumindo à extração dentária. O acesso precário dos ribeirinhos aos serviços de saúde bucal aponta para a necessidade de implantação de medidas amplas de promoção de saúde, aliada a maior oferta de serviços.
