RT Journal Article SR Electronic T1 The relationship between periapical lesions and the serum levels of glycosylated hemoglobin and C-reactive protein in type 2 diabetic patients JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 36 OP 40 DO 10.15537/smj.2017.1.16052 VO 38 IS 1 A1 Mohammad S.

Zawawi YR 2017 UL http://smj.org.sa/content/38/1/36.abstract AB Objectives: To investigate the relationship between the presence of periapical lesions (PL) and levels of glycosylated hemoglobin (HbA1c), and C-reactive protein (CRP) in patients with type 2 diabetes.Methods: This cross-sectional study was conducted at Ibn Sina National College for Medical Studies, Jeddah, Kingdom of Saudi Arabia, between September 2013 and February 2015. Medical and dental history and Sociodemographic data were obtained from participants. Dental and periodontal examinations were conducted and blood samples were obtained to determine levels of HbA1c and CRP. The presence of PL was recorded from panoramic and periapical radiographs. Descriptive statistics and multivariable linear and logistic regression models were used for data analyses.Results: One hundred patients were included; mean age was 48.9 ± 8.5 years. Of these patients, 14% had no PL, whereas 25% had one or 2 lesions, 32% had 3 or 4 lesions, and 29% had ≥5 PL. The mean HbA1c was 9.8% (± 2.5) mg/L and CRP was 6.9 mg/L (± 6.3). The presence of PL was significantly associated with a higher level of HbA1c independent of age, gender, probing depth, and plaque index (p=0.023). Individuals with PL were also more likely to have a high CRP level (>3 mg/L) independent of the previous covariates (odds ratio: 1.19; 95% confidence interval: 1.01-1.41).Conclusion: Periapical lesions are associated with a poorer glycemic control and a higher CRP level in type 2 diabetic patients.
