Title Individuals Suffering From Diabetes Are More Susceptible to Root Caries But Not Coronal Caries Compared to Those Without Diabetes
Clinical Question Are individuals suffering from diabetes more susceptible to dental caries than those without diabetes?
Clinical Bottom Line Individuals suffering from diabetes are not more susceptible to coronal caries compared with non-diabetic individuals. However, it is possible for diabetic individuals to be more susceptible to root caries compared to non-diabetic individuals.
Best Evidence  
PubMed ID Author / Year Patient Group Study type
(level of evidence)
17615017Hintao/2007105 Type II diabetic subjects and 103 non-diabetic subjects (control group).Cross-sectional
Key resultsType II diabetic subjects had a higher prevalence of root caries (40% vs 18.5% P=0.001) and a higher number of decayed/filled root surfaces (1.2 ± 0.2 versus 0.5 ± 0.1; P < 0.01) compared to non-diabetic subjects. However, there was no significant difference in the prevalence (83.8% versus 72.8%) and in decayed/filled surface (8.0 ± 9.4 versus 6.3 ± 7.5) of coronal caries in the two groups. The study concluded that individuals with Type II diabetes are at more risk of developing root caries but not coronal caries.
19177848Marin/2008105 diabetic subjects (Type I and Type II diabetes) and 70 non-diabetic subjects (control group).Cross-sectional
Key resultsBoth Type I diabetes and Type II diabetes groups showed no significant difference in the presence of caries, filled teeth and DMFT index compared to non-diabetic subjects.

Comments on
The Evidence
Hintao and Marin both reported cross-sectional studies in which the examiners were blinded as to the subjects’ diagnosis (diabetic or non-diabetic). While Marin’s study had all groups start at the same time with a completion rate >80%, Hintao’s non-diabetic group’s response rate was 70% and diabetic group’s response rate was 90%. All subjects were treated and examined in similar manner. Adequate follow up was done for all groups and compliance by patients was adequate. Recall bias is not applicable for these studies. No statement was provided for competing interests.
Applicability This information can be used in any professional setting for providing health education to diabetic patients irrespective of the type (I or II), especially with regards to the complications of diabetes on oral health. Since the subjects used in the study had blood glucose above or below 110mg/dl, this could be applicable to those with controlled or uncontrolled diabetes. Although the studies show that diabetic patients are not more susceptible to coronal caries than non-diabetics, both studies showed that they are more susceptible to periodontal disease.
