Association between perceived chewing ability and oral health-related quality of life in partially dentate patients

Abstract

BackgroundOne of the most immediate and important functional consequences of many oral disorders is a reduction in chewing ability. The ability to chew is not only an important dimension of oral health, but is increasingly recognized as being associated with general health status. Whether perceived chewing ability and oral health-related quality of life (OHRQoL) are correlated to a similar degree in patient populations has been less investigated. The aim of this study was to examine whether perceived chewing ability was related to OHRQoL in partially dentate patients.MethodsConsecutive partially dentate patients (N = 489) without signs or symptoms of acute oral disease at Tokyo Medical and Dental University's Prosthodontic Clinic participated in the study (mean age 63.0 ± 11.5, 71.2% female). A 20-item chewing function questionnaire (score range 0 to 20) was used to assess perceived chewing ability, with higher scores indicating better chewing ability. The 14-item Oral Health Impact Profile-Japanese version (OHIP-J14, score range 0 to 56) was used to measure OHRQoL, with higher scores indicating poorer OHRQoL. A Pearson correlation coefficient was calculated to assess the correlation between the two questionnaire summary scores. A linear regression analysis was used to describe how perceived chewing ability scores were related to OHRQoL scores.ResultsThe mean chewing function score was 12.1 ± 4.8 units. The mean OHIP-J14 summary score was 13.0 ± 9.1 units. Perceived chewing ability and OHRQoL were significantly correlated (Pearson correlation coefficient: -0.46, 95% confidence interval [CI]: -0.52 to -0.38), indicating that higher chewing ability was correlated with lower OHIP-J14 summary scores (p < 0.001), which indicate better OHRQoL. A 1.0-unit increase in chewing function scores was related to a decrease of 0.87 OHIP-J14 units (95% CI: -1.0 to -0.72, p < 0.001). The correlation between perceived chewing ability and OHRQoL was not substantially influenced by age and number of teeth, but by gender, years of schooling, treatment demand and denture status.ConclusionPatients' perception of their chewing ability was substantially related to their OHRQoL.

The assessment of prosthetic needs of ESRD patients and the general population in Poland on the basis of the Eichner classification and teeth number: A brief, preliminary report

“…14, 15 The very limited amount of available research showed that the frequency of prosthetic reconstructions usage among ESRD patients is very low. Musacchio et al remarked about the existence of a large group of edentulous patients undergoing dialysis, who do not use dentures.…”

Oral Health- Related Quality of Life Assessed in Adults: Integrative Review

“…Surge como instrumento único de avaliação em 13 estudos: na Jordânia (Al Habashneh et al, 2012); no Brasil (Pereira et al, 2009); Japão (Inukai et al,2010); na China (Zheng et al, 2011); no Irão (Motallebnejad et al, 2011); Finlândia (Miettinen et al, 2012;Rusanen et al, 2012;Silvola et al, 2012); Espanha (Gil-Montoya et al, 2013;Montero et al, 2009;Perea et al, 2013); Nova Zelândia (Thomson et al, 2006) e com indivíduos croatas e eslovenos (RenerSitar et al, 2008). É utilizado em simultâneo com outro instrumento numestudo desenvolvido noCanadá por Locker e Gibson (2005).…”

“…Destaca-se a utilização da variável referente à presença ou número de dentes naturais presente em 10 estudos (Gil-Montoya et al, 2013;Hsu et al, 2014;Inukai et al, 2010;Locker & Gibson, 2005;Montero et al, 2008;Motallebnejad et al, 2011;Perea et al, 2013;Pistorius et al, 2013;Wright, 2009;Thomson et al, 2006;); a presença de dentes deteriorados (cariados), perdidos ou obturados e doenças periodontais em 4 estudos (Montero et al, 2008;Montero et al, 2009;Motallebnejad et al, 2011;Thomson et al, 2006); a má oclusão avaliada em 4 estudos (Hsu et al, 2014;Rusanen et al, 2012;Sardenberg et al, 2011;Silvola et al,2012); a utilização de próteses dentárias em 3 estudos (Montero et al, 2008;Perea et al, 2013;Pistorius et al, 2013;Wright et al, 2009); a xerostomia em 2 estudos (Perea et al, 2013;Thomson et al, 2006); a dor facial em 2 estudos Zheng et al, 2011); as disfunções temporomandibulares em 3 estudos (Miettinen et al, 2012;Pereira et al, 2009;Rusanen et al, 2012) e a dor de dentes em apenas 1 estudo (Rener-Sitar et al, 2008).…”

Association Between Tooth Loss and Cancer Mortality in Elderly Individuals

“…In a Japanese intervention study of institutionalized elderly subjects, GOHAI scores were improved when denture treatment was performed (Naito et al 2010). Another recent study reported a significant association between decreased chewing ability and decreased OHIP score (Inukai et al, 2010).…”
