Edentulism in diabetics in comparison with non-diabetics


Diabetes mellitus is a typical endocrine illness thought to have an effect on greater than 500 million folks worldwide. Hyperlinks between diabetes and tooth loss from periodontitis have been reported (Dental Elf – 10th Sep 2021) in addition to hyperlinks with caries (Dental Elf – 11th Sep 2023).

The principle intention of this assessment was to evaluate the proof associated to the prevalence of edentulism amongst diabetic sufferers in comparison with non-diabetic folks.


Searches have been performed in PubMed and Cochrane Central Register of Managed Trials (CENTRAL) with no language restrictions. Two reviewers independently chosen research with observational research (cross-sectional, cohort or case-control) with the first intention of investigating the prevalence of edentulism in diabetic (kind 1, kind II or undefined) sufferers being thought of. Two reviewers extracted information with danger of bias being assessed utilizing the Newcastle-Ottawa Scale (NOS). Weighted imply prevalence was calculated, the percentages ratio (OR) and 95% confidence intervals (CIs) have been calculated for edentulousness amongst diabetic sufferers in comparison with these with out diabetes and meta-analysis performed.


  • 7 cross-sectional research involving a complete of 2216 edentulous circumstances have been included.
  • Research pattern sizes ranged from 293 to fifteen,943.
  • 4 research have been from Europe, 2 from North America and one from South America.
  • 5 research have been thought of to have a low danger of bias and a pair of a average danger.
  • Edentulism was assessed clinically in 6 research and from dental information within the different research.
  • 3 research centered on kind II diabetes, 4 research didn’t differentiate or specify kind.
  • The prevalence of edentulism among the many entire research inhabitants was 8.3% with a spread throughout the research of three.3% to 45%.
  • The general weighted imply prevalence of edentulism was 14.0% for diabetic sufferers and seven.1% amongst non-diabetic folks.
  • Prevalence of edentulism for sufferers self-reporting diabetes was 8% in contrast with 7.7% for clinically assessed diabetes.
  • Edentulism prevalence was 11.3% for Europe, 6.8% for North America and eight.4% for South America.
  • The percentages for being edentulous have been increased for diabetes that non-diabetics (see desk) under).
  No. of Research Odds ratio (95percentCI)
Total 7 2.39 (1.73 to three.28)
Self-reported diabetes 3 2.61 (2.15 to three.17)
Professionally recognized diabetes 3 2.39 (2.09 to 2.73)


The authors concluded: –

There seems to be average certainty that the chance of being edentulous for diabetic sufferers in comparison with non-diabetic folks is important, however the odds ratio is estimated to be small.


No protocol was registered for the assessment  however the authors adopted the Meta-Evaluation of Observational Research in Epidemiology (MOOSE) tips. Searches have been performed in two main databases with no language restrictions.  Seven research have been included with 5 being thought of to be at low danger of bias. All of the included research have been cross-sectional in nature which because the authors point out prohibits the inference of any causal relationship. The general estimate for the prevalence of edentulism derived from the 7 included research was (8.3% (vary 3.3% to 45%) which a lot decrease than the WHO estimate for the worldwide prevenance of edentulism of 26%. Whereas the findings of the assessment recommend increased ranges of edentulousness in diabetics the overall prevalence ought to be taken into consideration because the oral care system might affect the choices of sufferers and dentists. Future potential research the place are vary of potential confounders akin to age, gender, smoking, weight problems, socio- financial standing and many others are taken into consideration are wanted to offer extra readability on the connection between diabetes, tooth loss and edentulism.
