Aim. Qat chewing has been reported to induce subgingival microbial shifts suggestive of prebiotic-like properties. The objective here was to assess the effect of qat chewing on a panel of classical and new putative periopathogens in health and periodontitis.Materials and Methods. 40 qat chewers and 40 nonchewers, equally stratified by periodontal health status, were recruited. Taqman, real-time PCR was used to quantify total bacteria,Porphyromonas gingivalis,Tannerella forsythia,Treponema denticola,Parvimonas micra,Filifactor alocis, Synergistetes, and TM7s in pooled subgingival biofilm samples. Differences in microbial parameters between the study groups were analysed using ordinal regression.Results. In health, the qat chewers harboured significantly lower relative counts ofP. gingivalis,T. forsythia, Synergistetes, and TM7s after adjustment for multiple comparisons (P≤0.007). At nominal significance level, they also carried lower counts of TM7s andP. micra(P≤0.05). In periodontitis, the chewers had lower counts of all taxa; however, onlyT. denticolawithstood correction for multiple comparisons (P≤0.0063).Conclusions. Qat chewing is associated with lower proportions of periopathogens, particularly in subjects with healthy periodontium, which supports previous reports of its prebiotic-like properties. This potentially beneficial biological effect can be exploited by attempting to isolate the active fraction.

Abstract Periodontal disease is clearly correlated with systemic disease. The presence of periodontal pathogens in interdental spaces in young, healthy adults is a strong indicator of the need to introduce daily interdental prophylaxis. Twenty-five subjects (aged 18–35 years), diagnosticated clinically as periodontally healthy, were enrolled in this study. One hundred interdental sites were included. Among these sites, 50 “test” sites were cleaned daily with calibrated interdental brushes (IDBs), whereas the other 50 sites were not cleaned and considered “controls”. The interdental biofilm at these interdental sites was collected at the beginning of the study (basal) and at 1 week, 2 weeks, 3 weeks, 4 weeks, and 3 months. Real-time polymerase chain reaction (PCR) methodology was used to quantify (i) 19 periodontal bacteria, including Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, and (ii) total bacteria. In the test sites, the quantity of total bacteria decreased over time with the use of IDBs. The bacteria from the red and orange Socransky complexes, which are associated with periodontal disease, significantly decreased in the test sites but not in the control sites. Bacteria from the yellow, and purple Socransky complexes, which are associated with periodontal health, increased significantly in both groups whereas bacteria from the blue Socransky complex increased significantly only in the test sites. Furthermore, at basal, 66% of test sites and 68% of control sites bled during interdental brushing. These percentages decreased by 85% in 3 months for the test sites and by 27% in the control sites. In conclusion, the daily use of calibrated IDBs can reduce periodontal pathogens, reestablish symbiotic microbiota and, decrease interdental inflammation in interdental sites of healthy young adults.

The emergence and development of resistance to antibiotics in periodontal pathogens have affected the success rate of treatment for periodontitis. The development of new antibacterial strategies is urgently needed to help control and treat periodontal disease, and dental plaque microbiome studies offer a promising new angle of attack.

Background: The aim of the study is to assess the body balance and podological parameters and body composition of young footballers in the context of the control of football training. Methods: The study examined the distribution of the pressure of the part of the foot on the ground, the arch of the foot, and the analysis of the body composition of the boys. The pressure center for both feet and the whole body was also examined. The study involved 90 youth footballers from Olsztyn and Barczewo in three age groups: 8–10 years, 11–13 years old, and 14–16 years. The study used the Inbody 270 body composition analyzer and the EPSR1, a mat that measures the pressure distribution of the feet on the ground. Results: The results showed statistically significant differences in almost every case for each area of the foot between the groups of the examined boys. The most significant differences were observed for the metatarsal area and the left heel. In the case of stabilization of the whole body, statistically significant differences were noted between all study groups. In the case of the body composition parameters, in the examined boys, a coherent direction of changes was noticed for most of them. The relationships and correlations between the examined parameters were also investigated. The significance level in the study was set at p < 0.05. Conclusions: Under the training rigor, a statistically significant increase in stability was observed with age. The total length of the longitudinal arch of both feet of the examined boys showed a tendency to flatten in direct proportion to the age of the examined boys. Mean values of the body composition parameters reflect changes with the ontogenetic development, basic somatic parameters (body height and weight) and training experience, and thus with the intensity and volume of training. This indicates a correct training process that does not interfere with the proper development of the body in terms of tissue and biochemical composition.

Background: The Triggering Receptor Expressed On Myeloid Cells-1(TREM-1) is a cell-surface receptor of the immunoglobulin superfamily and found to be involved in the amplification of the inflammatory response to various microbial infections, including periodontal diseases.Objectives: The present study was designed to examine gingivalcrevicular fluid(GCF) levels of soluble TREM-1 (sTREM-1) levels in periodontal health and disease as well as evaluate the effect of scaling and/or root planing on the same.Methods: Based on gingival index, probing pocket depth, clinical attachment level, and radiologic parameters (bone loss), 45 subjects were initially divided into three groups- Group, I (Periodontally healthy), Group II (Gingivitis) and Group III (Chronic Periodontitis).From each of the subjects, GCF sample was collected at baseline and scaling and/or root planing was instituted in group II and group III patients. GCF samples were subsequently collected at eight-week interval. Levels of sTREM-1 in collected GCF samples were estimated using enzyme-linked immunosorbent assay.Results: The lowest GCF levels of sTREM-1 were found in periodontal health (69.50±1.8pg/ml) followed by gingivitis (257.17±79pg/ml) and chronic periodontitis (3658.14±55pg/ml) in increasing order, suggesting that levels of sTREM-1 in crevicular fluid increased with the severity of periodontal disease. sTREM-1 levels decreased significantly from baseline to the end of 8 weeks following non-surgical periodontal therapy.Conclusion: Increased GCF levels of sTREM-1 from periodontal health to disease strengthen its association with periodontal status.
