Biochemical, pathohistological, radiographic and cardiological analysis reveals the possible association between apical periodontitis and cardiac function in diabetic rats.

To evaluate the possible effects of apical periodontitis (AP) on cardiac function, structure, and oxidative stress (OS) in rats with diabetes mellitus type 2 (T2DM). Forty-eight (Wistar albino, male) rats were randomized into four groups: control healthy (CTRL), normoglycemic with AP (AP), T2DM, and T2DM with AP (T2DM+AP). T2DM was induced by streptozotocin and a high-fat diet. AP was induced by pulp exposure to the oral environment for 4 weeks and analyzed radiographically. In the blood samples insulin and glucose were established. In vivo, cardiac function was evaluated by echocardiography. Ex vivo cardiac function was assessed by the Langendorff technique. Heart tissue was analyzed pathophysiologically. OS was determined in cardiac tissue homogenate and coronary venous effluent, spectrophotometrically. Impaired glycoregulation was observed in the T2DM+AP group compared to the T2DM, AP, and CTRL groups. The T2DM+AP group was associated with disturbed echocardiography and cardiodynamic parameters. The levels of superoxide anion radical, nitrite, and index of lipid peroxidation were significantly increased, while the superoxide dismutase and catalase were significantly decreased in the T2DM+AP group compared to T2DM, AP, and CTRL groups. The radiographic AP area was significantly larger in the T2DM+AP compared to the AP group. AP was associated with increased glucose levels, impaired cardiac function, structure, and OS in diabetic rats. Diabetes was related to an increased radiographic AP area. The study may be a starting point for further research to clarify the effects of AP on cardiac function in various models of systemic diseases.

Enamel caries lesions, with and without initial cavitation, in relation to anatomical areas of the proximal surface in deciduous molars.

proximal enamel caries lesions (PEC) are believed to initiate and progress to cavitation below the proximal contact area (PCA), but no evidence exists on the location of initial carious cavitation on the proximal surface with functional PCA. This study aimed to test the association of anatomical areas of the proximal surface with the severity of PEC and the frequency of cavitation in PEC in primary molars DESIGN: laboratory, observational, transversal study. Exfoliated primary molars (n = 33) with functional PCA (biofilm-free PCA surrounded by biofilm) had their proximal surfaces (one/tooth) divided anatomically into up to nine areas: 3 areas based on the occlusal/cervical PCA boundaries (areas I, II, and III; occluso-cervically) and 3 areas based on the bucco/lingual PCA boundaries (A, B, and C), with area IIB representing the PCA and area IIIB as the sub-PCA (below the PCA). PEC (ICDAS scores 1 and 2-3) and cavitation in PEC were quantified in all areas using stereomicroscopy and microCT. PEC volume was quantified in areas IIB and IIIB under microCT RESULTS: PEC severity increased occluso-cervically. PCA and sub-PCA presented different PEC severities (higher in sub-PCA) and similar PCE volumes, but the odds of carious cavitation were much higher (Odds ratio = 197.4; 95 % CI: 8.7/4480.7) in the PCA than in the sub-PCA (no cavitation). PCA presented lower PEC severity and similar PEC volume compared to sub-PCA, but PCA concentrated all cavitations in PEC, supporting a new model for the pathogenesis of PEC.
