Association between metabolic control and oral health in children with type 1 diabetes mellitus

Abstract

Abstract Background Type 1 diabetes mellitus is the most common chronic disease and can be reflected in the oral cavity. The aim of this study was to analyze the impact of metabolic control on saliva, dental caries, dental plaque, gingival inflammation, and cariogenic bacteria in saliva. Methods A case–control epidemiologic study was performed on children with type 1 diabetes (ages 10–15 years) separated into two groups: 34 children with good metabolic control of glycated hemoglobin (HbA1c 7.5%). Oral status was assessed using the Decay, Missing, and Filled Teeth index for permanent teeth (DMFT), plaque index and gingival index. The stimulated salivary flow rate was measured, and the colonies of Streptococcus mutans and Lactobacillus in saliva were determined. The observed children answered questions related to their frequency of brushing habits, dental visits and parents’ education. Mann–Whitney U Test, Chi-Square test and Fisher’s exact test were used in the statistical analyses. The significance level was set at p 0.05). The majority of both groups with good and poor metabolic control brushed their teeth once per day, and they visited the dentist only when necessary (61.3%). However, the parents of children in both groups had medium to low levels of education, without any significant difference between groups (p > 0.05). Conclusion The results indicate that children with diabetes have a lower level of oral hygiene and are potentially to dental caries and periodontal diseases, mainly when their metabolic disorder is uncontrolled.
