DENTURES AND QUALITY OF LIFE – A LONGITUDINAL ANALYSIS S.A. GRAY, M.R. INGLEHART & D. SARMENT University of Michigan, USA This study was supported by funds from the University of Michigan School of Dentistry Student Research Program.
BACKGROUNDBACKGROUND Edentulism - Background Statistics 1983: -17% of US population is edentulous in at least one arch - 41% of the population 65 years or older are edentulous NHANES III – 1988 to 1994: -10.9% of white non Hispanic adults 35 years and over
Consequences of Edentulism: masticatory problems - poorer diets - nutritional deficiencies - systemic disturbancesspeech difficulties psychological / social issuesmasticatory problems - poorer diets - nutritional deficiencies - systemic disturbancesspeech difficulties psychological / social issues
OBJECTIVEOBJECTIVE Does wearing dentures lead to low oral health related quality of life (ohrqol)? How? For whom? When? Consequences?
HYPOTHESESHYPOTHESES HYPOTHESIS 1: Patients with different levels of discomfort due to dentures differ in: -functional considerations (chewing, speaking, swallowing), - psychological factors (appearance, self esteem), -social factors (smiling, interaction with peers), and -experienced pain.
HYPOTHESES (cont’d) HYPOTHESIS 2: A decline of ohrqol occurs in denture patients over time. HYPOTHESIS 3: Ohrqol will correlate significantly with the patients’ - age, and - general health status.
METHODSMETHODS Respondents: 120 former patients of undergraduate & graduate clinics (response rate = 28%) Gender:50 male & 70 female patients Age:34 to 93 years (mean: 66 years) Length of having dentures: 5 months to nine years (mean: 44 months).
MATERIALS How do we measure discomfort? People use the following five words to describe pain / discomfort of increasing intensity. Which word describes the level of discomfort that you have during an average week due to your dentures? 0 1 2 3 4 5 nomilddiscomfortingdistressinghorribleexcruciating discomfort
How do we measure ohrqol? When you think about your dentures: - On a scale from 1 “no discomfort” to 10 “worst discomfort possible”, how severe is this discomfort? - How effective are your dentures? 1 = not at all to 5 = very - How much do you think having dentures interferes with your life? 1 = not at all to 5 = very How much do you agree / disagree? 1= strongly disagree to 5=strongly agre My dentures limit the kinds or amounts of food I eat.

DISCUSSIONDISCUSSION Ohrqol = relatively new concept It focuses providers on ultimate outcome of care! With dentures: - 2/3 of patients report discomfort - discomfort = correlated with health! WHY?
CONCLUSIONCONCLUSION Providing the best possible care for edentulous patients will have an extraordinary impact on these patients' quality of life. OHRQOL = crucial outcome! Understand -how we can assess ohrqol, -how we can predict ohrqol, (example: orthognathic surgery) -which other factors affect ohrqol (depression?) -and how we can use ohrqol in treatment.
