Assessing the relationship between people at increased risk of developing diabetes and periodontitis: a systematic review study

Abstract

AbstractImpaired glucose tolerance is an intermediate condition between diabetes and normal blood glucose, in which blood glucose level has risen and is between 100–126mg/dL. Present evidence suggests that there is a relationship between poor control of diabetes and uncontrolled diabetes with periodontal disease. People with impaired glucose tolerance may have a more unfavourable periodontal condition than the general population with a mechanism similar to those with diabetes. Accordingly, the present study aims to assess the relationship between impaired glucose tolerance and periodontal disease using systematic review criteria.This study is a systematic review. The databases included PubMed, Science Direct, Scopus, Cochrane Library, and Google Scholar search engine. Two individuals independently selected studies based on the inclusion criteria. The Newcastle‐Ottawa Scale (NOS) checklist was used for quality assessment. Search management was conducted using EndNote software.After applying the inclusion and exclusion criteria, seven articles were included in the study. Regarding the pocket depth (PD) index, five studies stated that there is a relationship between impaired glucose tolerance status and the severity of the periodontal disease, and lower periodontal health was observed in groups with higher levels of blood glucose (p<0.05). With regard to the bleeding on probing (BOP) index, it should be stated that most studies have reported that there is a relationship with impaired glucose tolerance indices (p<0.05).This systematic review study suggested that there is a relationship between periodontal indicators and impaired glucose tolerance.
