Epidemiological trends, predictive factors, and projection of tooth loss in Germany 1997–2030: part I. missing teeth in adults and seniors

Abstract

Objective This is the first part of a report on tooth loss in Germany 1997–2030. Here, we describe trends in the prevalence of tooth loss in adults and seniors 1997–2014, assess predictive factors for tooth loss and projected it into 2030. Material and methods Data of the cross-sectional, multi-center, nationally representative German Oral Health Studies of 1997, 2005, and 2014 were used. Age, sex, educational level, smoking status, and the cohort were used for ordinary least square regression to assess the association of predictors with tooth loss (missing teeth, MT). The yielded regression coefficients were used to predict tooth loss in 2030. Results Compared with 1997, the mean MT in adults (35–44 years old) in 2030 was predicted to decrease by two-thirds to 1.3. The prevalence of tooth loss (MT > 0) will decrease by 72% from 1997 to 2030. In 2030, half of the population of adults will not exhibit any tooth loss. Compared with 1997, the mean MT among seniors (65–74 years old) will decline to 5.6 teeth (i. e. two-thirds reduction) until 2030. Prevalence of tooth loss will be halved by 2030, and approximately one-third of this age group will not exhibit any tooth loss. Conclusions Based on the model used, the trend of a robust decline in tooth loss will become more dynamic by the year 2030. As a result, every second adult will have experienced no tooth loss at all in 2030, and seniors will possess more teeth than they have previously lost. Clinical relevance This study presents the trends of tooth loss in Germany for a period of three decades. It provides clinically relevant data for health care planning by 2030.

Analysis of epidemiological trends of and risk factors for tooth loss among 35- to 44-year-old adults in Guangdong, southern China, 1995-2015

“…In the UK, the number of remaining teeth in adults increased from 21.9 in 1968 to 25.7 in 2009 [21]. In Germany, the prevalence of MT>0 decreased from 76.6% in 1997 to 58.8% in 2005 and to 56.8% in 2014 [22]. In addition, the mean number of MT in Brazil decreased from 13.5 in 2002-2003 to 7.4 in 2010 [23].…”

“…The global prevalence of edentulism continues to be high [16]. However, dental health care is focused on decreasing edentulism rate via increasing oral hygiene knowledge, preventive dental care, and treatment.…”

“…Despite of great strides in prophylaxis and a higher number of remaining teeth in the elderly by 2030 in Germany, the amount of patients in need of complete dentures due to edentulism will keep prevalent in industrialized countries, e.g., with about 1 to 2 million people in Germany during the upcoming decade [ 1 , 2 ]. Furthermore, complete tooth loss is a major burden of disease worldwide [ 3 ].…”
