ABSTRACT Objective: Generalized aggressive periodontitis (GAgP) is a complex periodontal disease affecting the entire dentition with a rapid destruction of the periodontium and resulting in loss of teeth. We hypothesized that better clinical healing of adjunctive use of amoxicillin plus metronidazole combination may be related to the effect of this combination therapy to restore imbalance between matrix metalloproteinases (MMP) and their tissue inhibitors (TIMP) which is associated with connective tissue and alveolar bone destruction in patients with GAgP. Materials and Methods: Twenty-eight subjects diagnosed with GAgP were recruited. Patients were randomly assigned to test or control groups. MMP-1/TIMP-1 ratio was compared between groups receiving scaling and root planning (SRP) alone (control) or in combination with amoxicillin plus metronidazole (test). Clinical periodontal variables were measured. Gingival crevicular fluid samples were obtained and analyzed for MMP-1 and TIMP-1. Measurements were taken at baseline and repeated at 3 and 6 months after therapy. Results: Total MMP-1 levels were significantly decreased in both groups (P < 0.05) at 3 and 6 months. MMP-1 concentration levels showed a similar pattern to MMP-1 total levels decreasing significantly at 3 months (P < 0.05). TIMP-1 concentration levels increased in the test group throughout the study period, while the difference did not reach statistical significance (P > 0.05). TIMP-1/MMP-1 balance was restored in test group at 6 months significantly better than the control group (P < 0.05). Conclusion: The results of this study suggest that metronidazole and amoxicillin combination as an adjunct to SRP results in better clinical healing through restoring TIMP-1/MMP-1 balance.

Summary Background: Aggressive periodontitis is one of the most severe forms of periodontal disease, resulting in the destruction of junctional epithelium and alveolar bone around teeth in a very short period of time. The early diagnosis of aggressive periodontitis and timely therapy is of outmost importance in controlling the progress of the disease.Application of the techniques of subgingival air polishing of periodontal pockets (pflow) with glycine powder has contributed to reduce damage to the root surface of the teeth and surrounding soft tissue.Aim: The goal of this paper was to determine the effectiveness of two different types of subgingival air polishing therapy for the periodontal tissue status at the patients with aggressive periodontitis.Methods and materials: the study included 46 patients of both sexes diagnosed with aggressive peridontitis. The patients were divided into two groups: test group (PFLOW), and control group (sonic SRP). The size of the destruction of periodontal tissue was estimated by CAL and assessment of oral hygiene and gingival inflammation was performed using FMPS and FMBS.Results: Monitored indexes values in both groups were reduced.Conclusion: Subgingival air polishing showed equally good results as the SRP, while pflow was more advantageous with respect to patients acceptability, time usability and safety for the soft tissue.

Haim-Munk syndrome is an extremely rare autosomal recessive disorder characterized clinically by palmoplantar hyperkeratosis, aggressive periodontitis with severe alveolar bone destruction, onychogryphosis, pes planus, arachnodactyly, and acro-osteolysis. Consanguinity seems a notable prerequisite. The aim of this study was therefore to report one case of this syndrome and to focus on the periodontal manifestations, in order to attract the attention of dental clinicians to this rare anomaly.

Abstract Objective: Matrix metalloproteinases (MMPs) are important regulators of vascular and uterine remodeling. Normal pregnancy is associated with increased MMP activity. Measurements of the plasma levels on MMPs have not been consistent between studies in complicated pregnancies. We have examined MMP-9, MMP-2 and their respective tissue inhibitors TIMP-1 and TIMP-2 in different time points in the sera of 13 women with normal pregnancy. Results: The serum levels of MMP-9 and TIMP-1 were stable throughout pregnancy. The level of MMP-2/TIMP-2 complex was slightly increased after week 15 without statistical significance. The serum levels of MMP-9, MMP-2/TIMP-2 and TIMP-1 on different time points during normal pregnancy are poorly studied and further measurements of the plasma levels of MMPs and the correlation with MMP levels in the placenta and other maternal tissues are needed.

Chronic rhinosinusitis with nasal polyps is a multifactorial disease of the nasal and paranasal sinus mucosa and it includes, as comorbidities, anatomic and morphologic alterations, allergic rhinitis, and immunologic diseases. We investigated matrix metalloproteinases (MMP-2, MMP-7, and MMP-9) and their tissue inhibitors (TIMP-1 and TIMP-2) concentration in different etiopathogenetical groups of patients with nasal polyposis (NP) in relation to recurrence after sinonasal surgery. The study group consisted of 45 patients with NP (those with allergic rhinitis, nonallergic rhinitis and asthma or nonallergic rhinitis, and obstruction of osteomeatal complex [OMC]) who underwent endonasal sinus surgery. We also collected 10 patients who underwent septoplasty as control. Immunohistochemistry of nasal mucosa fragments, Western blotting, and polymerase chain reaction analysis showed increased MMPs levels (MMP-9 more than MMP-2 and MMP-7) and decreased tissue inhibitors of MMPs levels (TIMP-1 less than TIMP-2), in patients with chronic rhinosinusitis with nasal polyps compared with control group, in particular in patients with nonallergic rhinitis and asthma compared to those with allergic rhinitis and nonallergic rhinitis and obstruction of OMC. We observed a higher risk of recurrence in patients with nonallergic rhinitis and asthma than in those with allergic rhinitis and nonallergic rhinitis and obstruction of OMC after 36 months from surgery. In this research, we evaluated pathogenesis of NP related to MMPs and their inhibitors concentrations in polypoid tissue.

Background Aggressive periodontitis is a specific type of periodontitis with clearly identifiable clinical characteristics such as “rapid attachment loss, bone destruction” and “familial aggregation”. Regeneration of mineralized tissues affected by aggressive periodontitis comprises a major scientific and clinical challenge. In recent years some evidence has been provided that bioactive glass is also capable of supporting the regenerative healing of periodontal lesions. Objective The aim of this clinical and radiological prospective study was to evaluate the efficacy of bioactive glass in the treatment of intra-bony defects in patients with localized aggressive periodontitis. Methods Twelve localized aggressive periodontitis patients with bilaterally located three-walled intra-bony defect depth ? 2 mm, preoperative probing depths ? 5 mm were randomly treated either with the bioactive glass or without the bioactive glass. The clinical parameters plaque index, gingival index, probing depth, gingival recession, clinical attachment level, and mobility were recorded prior to surgery as well as 12 months after surgery. Intraoral radiographs were digitized to evaluate the bone defect depth at baseline and 12 months after the surgery. Results After 12 months, a reduction in probing depth of 3.92 + 0.313 mm (P <0.001) and a gain in clinical attachment level of 4.42+0358mm (P <0.001) were registered in the test group. In the control group, a reduction in probing depth of 2.5 +0.230mm (P <0.001) and a gain in clinical attachment level of 2.58 + 0.149 mm (P<0.001) was recorded. Radiographically, the defects were found to be filled by 2.587 + 0.218 mm (P <0.001) in the test group and by 0.1792 + 0.031mm (P <0.001) in the control group. Changes in gingival recession showed no significant differences. . Conclusion Highly significant improvements in the parameters Probing depth, Clinical attachment level, and Bone defect depth were recorded after 12 months, with regenerative material.

Aim. To evaluate, with three-dimensional analysis, the effectiveness of alveolar ridge preservation (ARP) after maxillary molar extraction in reducing alveolar bone resorption and maxillary sinus pneumatization when compared to unassisted socket healing. Methods. Patients were included in the study following inclusion criteria and underwent minimally traumatic maxillary molar extraction followed by ARP using synthetic nanohydroxyapatite (Fisiograft Bone, Ghimas, Italy) (test group) or unassisted socket healing (control group). Cone-beam computerized tomographies (CBCT) were performed immediately after tooth extraction (T0) and 6 months postoperatively (T1). CBCTs were superimposed by using a specific software (Amira, Thermo Fisher Scientific, USA) and the following items were analyzed in both groups: (i) postextractive maxillary sinus floor expansion in coronal direction and (ii) postextractive alveolar bone dimensional changes (both vertical and horizontal). All data were tested for normality and equality of variance and subsequently analyzed by independent samples T-test and Mann–Whitney test. Results. Thirty patients were treated by three centers and twenty-six (test n=13; control n=13) were included in the final analysis. Mean sinus pneumatization at T1 was 0.69±0.48 mm in the test group and 1.04±0.67 mm in the control group (p=0.15). Mean vertical reduction of the alveolar bone at T1 was 1.62±0.49 mm in the test group and 2.01±0.84 mm in the control group (p=0.08). Mean horizontal resorption of crestal bone at T1 was 2.73±1.68 mm in test group and 3.63±2.24 mm in control group (p=0.24). Conclusions. It could be suggested that ARP performed after maxillary molar extraction may reduce the entity of sinus pneumatization and alveolar bone resorption, compared to unassisted socket healing. This technique could decrease the necessity of advanced regenerative procedures prior to dental implant placement in posterior maxilla.

Periodontal disease (PD) is one of the main causes of tooth loss and is related to oxidative stress and chronic inflammation. Although different treatments have been proposed in the past, the vast majority do not regenerate lost tissues. In this sense, the use of dental pulp mesenchymal stem cells (DPMSCs) seems to be an alternative for the regeneration of periodontal bone tissue. A quasi-experimental study was conducted in a sample of 22 adults between 55 and 64 years of age with PD, without uncontrolled systemic chronic diseases. Two groups were formed randomly: (i) experimental group (EG) n=11, with a treatment based on DPMSCs; and a (ii) control group (CG) n=11, without a treatment of DPMSCs. Every participant underwent clinical and radiological evaluations and measurement of bone mineral density (BMD) by tomography. Saliva samples were taken as well, to determine the total concentration of antioxidants, superoxide dismutase (SOD), lipoperoxides, and interleukins (IL), before and 6 months after treatment. All subjects underwent curettage and periodontal surgery, the EG had a collagen scaffold treated with DPMSCs, while the CG only had the collagen scaffold placed. The EG with DPMSCs showed an increase in the BMD of the alveolar bone with a borderline statistical significance (baseline 638.82±181.7 vs. posttreatment 781.26±162.2 HU, p=0.09). Regarding oxidative stress and inflammation markers, salivary SOD levels were significantly higher in EG (baseline 1.49±0.96 vs. 2.14±1.12 U/L posttreatment, p<0.05) meanwhile IL1β levels had a decrease (baseline 1001.91±675.5vs. posttreatment 722.3±349.4 pg/ml, p<0.05). Our findings suggest that a DPMSCs treatment based on DPMSCs has both an effect on bone regeneration linked to an increased SOD and decreased levels of IL1β in aging subjects with PD.

Diabetes mellitus types 1 and 2 are chronic diseases that cause serious health complications, including dermatologic problems. The diabetic skin is characterized by disturbances in collagen metabolism. A tissue remodeling depends on the degradation of extracellular matrix through the matrix metalloproteinases, which are regulated by e.g. the tissue inhibitors of metalloproteinases. The balance between matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) is essential to maintain homeostasis in the skin. The aim of this study was to determine the concentration of metalloproteinase 2, tissue inhibitor of metalloproteinase 3 and the concentration of collagen type 1 in unwounded skin of diabetes type 1 and 2 and healthy controls. The treatment of diabetes resulted in a significant decrease of MMP2, increase of TIMP3 and COL1 concentrations in the skin as compared to the untreated diabetic skin. The concentrations of MMP2 in the skin of treated rats did not show significant differences from the healthy control group. TIMP3 concentrations in the skin of treated rats are not returned to the level observed in the control group. Disturbances of the extracellular matrix of the skin are similar in diabetes type 1 and 2. Application of insulin in diabetes therapy more preferably affects the extracellular matrix homeostasis of the skin.

Physiotherapy in patients after laparoscopic cholecystectomy (CHL) is impeded by post-operative pain which causes a decline in patients’ activity, reduces respiratory muscle function and affects patients’ ability to look after themselves. The aim of this study was to assess the influence of Kinesio Taping (KT) on the increase in effort tolerance in patients after laparoscopic cholecystectomy. The task of the research was to compare results of 100-meter walk test in test group and control group before surgery, during and after physiotherapy. The research included 63 patients after CHL treated in General Surgery Department of Hospital in Nysa. Both test group (BA) and control group (KO) included randomly selected volunteers who met test qualification criteria. BA group consisted of 32 patients (26 females and 6 males), KO group consisted of 31 patients (22 females and 9 males). Both groups were subjected to complex physiotherapy and group BA had additional KT applications. The results were subjected to statistical analysis with the use of U MannWhitney test. The level of statistical significance was established at p < 0.05. The results showed that in the test conducted before surgery the level of median time recorded in the 100-meter test did not differ significantly between the two research groups. In further tests, the 100-meter walk test time was significantly shorter in the test group in comparison with the patients from the control group. Conclusion: The improvement in effort tolerance observed in the research indicates the efficiency of Kinesio Taping as a method complementing physiotherapy in patients after laparoscopic cholecystectomy.Keywords: Kinesio Taping, laparoscopic cholecystectomy, physiotherapy.

This article describes a double-blinded, placebo-controlled randomised clinical trial thatinvolved 30 eligible subjects experiencing generalised aggressive periodontitis. Subjectswere randomly assigned to either the test group (scaling and root planing + metronidazole[400 mg]) and amoxicillin [500 mg]) or the control group (scaling and root planing withoutthe adjunctive antibiotics combination). Both antibiotics and placebos were administeredthree times per day for 14 days. Participants were examined at baseline, and again six monthsand one year after therapy. Both therapies led to a statistically significant improvementin all clinical parameters as measured after one year. However, subjects who received themetronidazole–amoxicillin combination showed the greatest reduction in mean probingdepth, an improved clinical attachment level and a lower mean number of residual sitesafter one year. The investigators concluded that the non-surgical treatment of generalisedaggressive periodontitis was markedly improved by the adjunctive use of metronidazole andamoxicillin up to one year after treatment.
