Abstract
OBJECTIVE: To analyze the influencing factors of dentition defect in people with type 2 diabetes mellitus (T2DM) and periodontitis and to provide evidence-based support for improving the oral health and quality of life of T2DM patients. METHODS: A total of 169 patients with T2DM and periodontitis were selected by convenience sampling. According to the number of remaining teeth, the subjects were divided into two groups, group A (number of remaining teeth in the mouth≥20, n=115) and group B (the number of remaining teeth in the mouth<20, n=54). Questionnaire surveys, systemic and oral examinations, and laboratory blood tests were performed. Systematic influencing factors of dentition defect in people with T2DM and periodontitis were analyzed with logistic regression. RESULTS: Compared with patients in group A, patients in group B had higher findings in age, systolic blood pressure (SBP), prevalence of coronary heart disease and hyperlipidemia, glycosylated hemoglobin (HbA1c), periodontal probing depth (PD), and clinical attachment loss (CAL). Furthermore, their behaviors and awareness of oral health were not as good as those of patients in group A. Logistic regression showed that age, HbA1c, and SBP were independent risk factors for the number of remaining teeth in the mouth <20 among T2DM patients with periodontitis ( P<0.05). CONCLUSION: Increasing age, lower HbA1c, and increased SBP are the most important influencing factors for the number of remaining teeth in the mouth <20 in T2DM patients with periodontitis. Clinical practitioners should give more attention to the general health status of the patients and strengthen health education, thereby improving patients' quality.
