Literature on non surgical periodontal therapy (NSPT) shows lack of clarity in reporting information on re-evaluation timing and clinical response. If the re-evaluation was done shortly after NSPT, this is also likely to have an influence on the surgical treatment plan. The aim of this prospective clinical trial is to investigate the effect of re-evaluation timing at 1-3-6 months after NSPT in terms of pocket closure, PD reduction, comprehensive treatment plan, and costs for the patient.
Inflammation is a common factor of chronic periodontitis and diabetes. However, to date, there is no scientific evidence supporting a causal effect of the inflammation created by apical periodontitis on the onset of insulin resistance and on metabolic derangement in the condition of pre-diabetes or diabetes. A case control study has been designed in order to evaluate serum levels of pro-diabetes inflammation factors in a sample of healthy patients between 25 and 55 years of age, with or without apical periodontitis,before endodontic treatment and at 6 and 12 months post-treatment. The aim of the study is to evaluate any relation between the presence of chronic endodontic lesions and pro-diabetes inflammation factors that can promote the onset of insulin resistance, and whether endodontic treatment can reduce these factors, thus preventing a pro-diabetes status.
Apical periodontitis is an inflammatory process located around the apex of the root. It is mainly caused by a microbial infection of the pulp space. Diabetes mellitus and tobacco smoking are modulating factors that may influence the healing of apical periodontitis. Present studies have disclosed an association between smoking and apical periodontitis and diabetes mellitus and apical periodontitis. The aim of this study is to compare the healing of periapical bone in smokers and non-smokers and patients with diabetes mellitus type 2 and healthy participants. The hypothesis of this study is that smokers and patients diagnosed with diabetes mellitus will experience slower healing with a lower success rate in comparison to control groups. Apical periodontitis will be diagnosed through means of clinical examination and radiological analysis. Healing of apical periodontitis will be determined using periapical radiographs utilizing periapical index. This prospective study will contribute to the development of clinical guidelines concerning smokers and patients with diabetes mellitus type 2.
Background: The aim of the study is to find out the prevelance of VDR (rs731236), IL1B (rs1143634) and IL1A (rs1800587)gene polymorphisms in Turkish population and their association with stage III grade B / C periodontitis. Methods: Individuals who were found to be systemically and periodontally healthy (N = 100) after clinical and radiographic examination and who were diagnosed with Stage III Grade B / C periodontitis (N = 100) were included in the study. Gingival index, Plaque index, bleeding on probing, clinical attachment level and pocket depths of the patients were recorded. subjects genotyped for rs731236, rs1143634 and rs1800587 gene polymorphisms with Real Time Polymerase Chain Reaction.
The aim of this study is to evaluate the effects of cryotherapy applications on the inflammatory cytokine and collagenase matrix metalloproteinase levels during root canal treatment and postoperative pain intensity and incidence. Mandibular premolar teeth of 60 male patients within the 20-30 years old range, diagnosed with asymptomatic apical periodontitis will be included to the study for this purpose. The experimental protocols consist clinical and laboratory phases. In clinical phase, procedures of cryotherapy and control groups will be applied in 2-visit-root canal treatment. The samples, which were collected during root canal treatment, will be subjected to enzyme-linked immunosorbent assay (ELISA) analysis in laboratory. Levels of interleukin and inflammatory destructive enzymes will be determined in collected samples. During the analysis of visual analogue scale scores, the correlation between the changes of the cytokine and proteolytic enzyme levels and presence and intensity of pain will be evaluated.
Aim To evaluate the clinical and microbiological effects of a hyaluronan (HY) as adjunct to scaling and root planning of residual pockets during supportive periodontal therapy. Material and Methods Sixty-six chronic periodontitis, that have completed the active phase of treatment and are enrolled in a supportive periodontal therapy scheme, with 4 to 8 interproximal sites with PD ≥ 5 mm < 8 mm and presence of BoP at the revaluation examination will be randomly assigned to the test (HY containing gel) or control group. Immediately after debridement of the residual pockets the test gel (GUM® Afta Clear Gel, Sunstar) will be applied into the experimental sites by the operator. Further, the participants will be instructed to apply at the experimental sites the test gel supragingivally with an interdental brush (TePe, Malmö, Sweden), once per day after tooth brushing for the first 3 months. Subgingival gel application will be repeated at the 3-month control in persistent pockets (i.e. PD ≥ 5mm + BoP). CAL, PD, BoP, and presence of plaque will be evaluated at baseline and thereafter every 3 months (i.e., after 3, 6, 9, and 12 months). Further, subgingival microbiological samples will be collected from the 4 experimental sites at baseline, 3, 6, and 12 months. Nine periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia, Parvimonas micra, Campylobacter rectus, Eikenella corrodens), total bacterial load, and amount of Candida albicans will be determined quantitatively by real-time PCR.
Periodontitis is an inflammatory disease with an infectious character, where, as the result of the host response to a dysbiotic microflora, attachment and bone loss occur. The host response and the healing period following the treatment differs among individuals, but the reason behind is not fully understood. The macrophages and T cells play an important role in the immune response and in the pathogenesis of periodontal diseases, but their role in the healing following periodontal therapy is not known. In this study, we aim to reveal the effects of initial macrophage and T cell activities in the gingival tissue on the differences of the response to phase I periodontal treatment. 42 individuals will be included in the study. Granulation tissue samples will be collected from two separate deep pockets of each individual, initially. At the same session, full-mouth scaling and root debridement will be conducted. Saliva, subgingival biofilm and gingival crevicular fluid (GCF) samples will also be collected, initially, and at the 2nd, 6th, 12th and 24th weeks. At the same appointments, periodontal parameters will be recorded. When the clinical procedures are concluded, the samples will be sent to Turku University with dry ice. Tissue and GCF concentrations of related cytokines will be analyzed with Luminex. The density of macrophage types will be defined by immunoblot analysis of related markers. Macrophage subpopulations in tissues will be specified by proteomics. Likewise, quantities of periodontal pathogens will be evaluated with DNA isolation and next generation sequencing.
Periodontitis may contribute to vascular damage, resulting in the destabilization of atherosclerotic plaque leading to acute coronary syndrome (ACS). In this study, we explored the effect of non-surgical periodontal treatment (NSPT) on cardiovascular blood biomarkers and gingival crevicular fluid (GCF) Neutrophil Elastase (NE) and α1-proteinase inhibitor (alpha-1PI) levels in periodontitis (P) participants with and without ACS. Medical and dental examinations were performed to diagnose ACS and periodontitis, respectively. Seventeen patients with diagnosis ACS and periodontitis were included in this study, as a test group (Group ACS). Twenty-six, age and sex-matched control patients with periodontitis (Group P) were otherwise systemically healthy. Both groups received NSPT. Plasma levels of cholesterol, triglyceride, high-density lipoprotein (HDL), low-density lipoprotein (LDL), C-reactive protein (CRP), GCF NE activity, and GCF α1-PI levels were measured baseline, at1st and 3rd months after NSPT.
Papillae tunneling techniques (PTT) are a new approach toward regeneration of isolated intrabony defects. Compared to regular papillae preservation techniques, PTT rely on complete preservation of involved interdental papillae, providing optimal healing environment for periodontal wound. Surgical access is therefore gained either by vertical incision in vestibulum, or by short releasing incision on adjacent tooth. Interdental tissue is then carefully raised in a full thickness manner by tunneling instruments, root surface thoroughly cleaned by the ultrasound scaler or Gracey curettes and defect filled with the biomaterial of choice. While the success and aesthetic results of non-incised papillae techniques are well documented, no paper so far compared clinical results of papillae preservation techniques with different biomaterials. Therefore, the aim of our study is to compare gain of clinical attachment level (defined by sum of pocket probing depth and recession) to regular papillae preservation techniques, and to prove non-inferiority of Gel 40® (collagen matrix, loaded with micronized heterologous bone) to Gen-Os® (granulated cortico-cancellous heterologous bone mix). Secondary objectives include analysis of aesthetic parameters - differences in recession and tip of the papillae location before and after the treatment.
