AIM: Due to its potential to influence systemic inflammation and oxidative stress, and to predispose to bacterial infections, sleep duration could potentially be a risk factor for periodontitis. The aim of this cross-sectional study was to evaluate if there was in 2012 an association between periodontitis and sleep duration in a representative sample of the South Korean population. MATERIALS AND METHODS: A total of 5,812 subjects representative of 39.4 million of adults were examined...

OBJECTIVES: The aim of this study was to examine the association between periodontal disease and renal function in elderly women with different genotypes. MATERIAL AND METHODS: A total of 332 postmenopausal never-smoking women were analyzed. Poor renal function was defined as serum cystatin C >0.91 mg/L. Periodontal disease markers such as periodontal inflamed surface area (PISA) were evaluated. Selected variables, including PISA quartile, body mass index (BMI), HbA1C and age in Arg allele carriers and non-carriers based on the beta-3 adrenergic receptor, or between Ala allele carriers and non-carriers based on peroxisome proliferator-activated receptor gamma, were analyzed using multiple logistic regression analysis...

We have read with great interest the recent article by Turkal et al. (2016). In their study, the results obtained with enamel matrix derivative (EMD) and EMD + platelet-rich fibrin (PRF) were compared in the treatment of intrabony defects in patients with chronic periodontitis. The authors concluded that both therapies resulted in significant clinical improvement in intrabony defect treatment, but addition of PRF did not improve the clinical and radiographic outcomes. A recent review article provided the biological background for the use of EMD and discussed the current evidence for periodontal regeneration (Miron et al...

AIM: to test whether or not the use of a volume stable collagen matrix (VCMX) results in soft tissue volume increase at implant sites non-inferior to an autogenous subepithelial connective tissue graft (SCTG). METHODS: In 20 patients soft tissue augmentation at implant sites was performed using VCMX or SCTG. Casts obtained prior to augmentation (BL), at 30 (FU-30) and 90 days (FU-90) were digitized and transferred to stereolithography (STL) files. BL, FU-30 and FU-90 STL files were superimposed and linear volumetric changes evaluated in crestal and buccal regions of interest (ROI)...

AIM: The bone implant contact (BIC) has traditionally been evaluated with histological methods. Thereupon, strong correlations of 2-dimensional (2D) BIC have been detected between μCT and destructive histology. However, due to the high intra-sample variability of BIC values, one histological slice is not sufficient to represent 3D BIC. Therefore, our aim has been to correlate the averaged values of 3-4 histological sections to 3D μCT. MATERIAL AND METHODS: Fifty four implants inserted into the maxilla of 14 minipigs were evaluated...
