Locally Delivered Antibiotics for the Treatment of Periodontitis

The sample consists of patients with moderate to severe periodontitis who will be subjected to machanical therapy in combination to local antibiotics. The participants will be divided into two groups, mechanical therapy with metronidazole hyclate, and mechanical therapy with minocycline hydrochloride. Both antibiotics will be delivered locally as gels. Outcome measures include probing pocket depth and several gingival indices. IL6 will be also measured for all participants.

Efficacy of Adjunctive Antimicrobial Photodynamic Therapy for Residual Pockets in Previously Surgically Treated Teeth

Traditionally, periodontal gum surgery has been used as a method to gain access to inflamed periodontal pockets around teeth. The outcome of these surgeries, however, is not always successful as there can be recurrence of inflammation and disease. The objective of this study is to assess the effectiveness of antimicrobial photodynamic therapy as an adjunct to mechanical debridement of residual periodontal pockets in patients having undergone periodontal surgery. Pocket probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) will be evaluated at all sites as measures of inflammation and disease resolution.

Treatment of Periodontal Disease in Systemic Lupus Erythematosus

Many studies have conducted to evaluate the relationship of systemic inflammatory diseases with periodontal disease. Previous evaluations suggest that there is no significant association between patients with Systemic lupus erythematosus (SLE) and Periodontitis (PD). However, some of the studies have shown relevancy between these two inflammatory diseases and have suggested to explore more for further knowledge. The aim of the study is to establish and investigate a relationship between SLE and PD. The study which will take place in two centers and will recruit 30 patients which will enter a pilot randomized controlled trial. Individuals enrolled into the study will be randomly assigned to the test or control group in a 1:1 ratio. Study will be divided in to six visits for the patients and the length of the study will be of 6 months. Visit 1 will be consisting of Screening including consent and Periodontal examination of the patients. Visit 2 includes orthopantomogram (OPG), Comprehensive periodontal examination recording, Blood samples collection vascular function assessment and optical coherence tomography (OCT). Intensive periodontal treatment (IPT) for test group and control periodontal treatment (CPT) for control group including medical history recording according to group allocation in visit 3 for control group and (3a and 3b) for test group will take place. Follow ups after two months will be conducted in Visit 4 for both groups including Demographics, medical history and concomitant medications recording, comprehensive periodontal examination recording, OCT, blood samples/saliva samples collection and vascular function assessment. Visit 3 and 5 will be conducted as periodontal treatment (IPT for test group and CPT for the control group), medical history recording, including demographics, Alogrithm for cardiovascular disease (Qrisk3) questionnaire (Visit 3 only) to assess the cardio-vascular risk medical history and concomitant medications recording, comprehensive periodontal examination recording, blood samples collection and vascular function assessment. Last visit will be 6 months follow up.

Tongue Dysbiosis Effects on Arterial Pressure of Periodontitis Patients

Blood pressure control is crucial for individuals' wellbeing. However, many daily aspects such as diet could impair blood pressure control. In addition, many people living under different conditions in different countries are affected by some kind of gum disease. These people experience gingival bleeding, bad breath, teeth mobility and pain. Throughout gum disease development the number of oral germs in the mouth increases including their levels in tongue surface. Oral bacterial are able to convert nitrate widely found in food in nitrite which influences blood pressure. Frequently treatment of gum diseases general combines manual instrumentation with mouthwashes. However, it has been suggested that reduction of oral bacteria by mouthwashes, especially chlorhexidine, is accompanied by decreased conversion of nitrate to nitrite and that this minor nitrite availability would increase blood pressure. Therefore, this is a point to be clarified for patients, physicians and dentists. This study will investigate the relation between treatment with mouthwashes and blood pressure of patients with destructive gum disease based on nitrite levels in saliva, bacterial levels in tongue and values of arterial blood pressure which will be monitored over 6 months. In addition, usual clinical parameters and alteration of oral cells' DNA will be also monitored overtime. Patients will be treated under local anesthesia and manual instrumentation within 24 hours. They will receive oral care products too. There will be 3 treatment groups (manual instrumentation + chlorhexidine mouthwash [2 times a day for 3 weeks], manual instrumentation + placebo mouthwash [2 times a day for 3 weeks] and manual instrumentation + no mouthwash) and 2 dental appointments before treatment. After treatment, patients will be examined at 7, 14, 21, 90 and 180 days. Saliva, plaque and cell sampling will be fast and by no invasive methods.

Running Title: PPAR-?, RXR-?, and VDR Expressions in Periodontitis

Objective: The present study aimed to determine the expressions of nuclear receptors PPAR (Peroxisome proliferative activator receptor)-?, RXR (Retinoid X receptor)-?, and vitamin D receptor (VDR) in healthy volunteers and periodontitis patients with different grade involvement. Methods: Group-1; healthy individuals, Group-2; periodontitis patients-stage 3 grade B, (H-GradeB), Group-3; periodontitis patients-stage 3 grade C, (D-GradeC). Clinical parameters as plaque index (PI), gingival index (GI) and clinical attachment levels (CAL) were measured. Fibroblast and inflammatory cells, PPAR-?, RXR-?, and VDR levels were determined in histological slides.

Influence of Gum Disease Treatment on Long-term Dental Implant Success

The aim of this study is to evaluate the influence of periodontal care response on long term dental implant success. Investigator's hypothesis is that patients who do not well respond to periodontal care have more chance to develop peri-implant complications at long-term. The second purpose of this study is to evaluate the influence of other local, systemic, behavioral, and implant's related risk factors

Chronic Periodontitis and Tooth Loss in Patients With Rheumatoid Arthritis

Periodontitis is a highly prevalent chronic inflammatory disease that is characterized by loss of the periodontal ligament and alveolar bone, and is a major cause of tooth loss. Results from clinical and epidemiological studies have suggested that periodontitis and tooth loss are more prevalent in individuals with rheumatoid arthritis (RA). There is evidence to suggest that periodontitis could indeed be a causal factor in the initiation and maintenance of the autoimmune inflammatory response that occurs in RA. If so, chronic periodontitis might represent an important modifiable risk factor for RA. However, to date longitudinal studies on the effect of periodontitis on disease progression in RA are lacking. The aim of the present study is to assess the periodontal status of patients enrolled in an established longitudinal cohort of RA patients. These data will then be analysed to evaluate whether or not periodontal inflammation is related to parameters of rheumatoid arthritis.
