Active clinical trials for "Periodontitis"

To evaluate the respective or combinatory efficacy of locally delivered 2% Minocycline (MO) and surface and root planning (SRP) by assessing both clinical parameters and the loads of four main periodontal pathogens in treating chronic periodontitis.

Background: To compare the effectiveness of open flap debridement (OFD) alone and OFD along with either Autologous Platelet Rich Fibrin (PRF) or Titanium Platelet Rich Fibrin (TPRF) in the treatment of intrabony defects (IBDs). Materials and methods: Study was conducted on subjects reporting to the Department of Periodontics, The Oxford Dental College and Hospital, Bangalore. 38 subjects with 90 periodontal IBDs of moderate to severe periodontitis were selected and assigned to OFD alone (group I) or OFD with Autologous PRF (group II) or OFD with TPRF (group III). In each subject, a minimum number of two sextants were present with probing pocket depths (PPD) ≥5mm in at least three teeth.

The present study is designed to investigate the effectiveness of AV gel local drug delivery as an adjunct to scaling and root planing (SRP) in the treatment of subjects with chronic periodontitis (CP) and type 2 diabetes mellitus (DM).

In the past few years, studies have evaluated the effect of systemic use of sodium alendronate, especially in the treatment of structural bone defects caused by periodontal diseases. This study evaluated the effects of non-surgical periodontal treatment associated with the topical application of 1% sodium alendronate on clinical and topographical parameters. Chronic periodontitis patients were recruited for the present study and were monitored at 3 and 6 months after baseline examinations. A placebo gel was used as control.

Periodontitis, a bacterial dental biofilm based infectious disease, is a chronic inflammatory disease of the periodontium which results in irreversible destruction of supporting structures of the teeth such as periodontal ligaments, connective tissues, cementum and alveolar bone. More than 700 species of bacteria are estimated to be found in the sub-gingival dental biofilm in which periodontopathogens are found to be responsible in initiating periodontal disease. Chronic periodontitis, although termed as 'chronic', starts as an acute inflammation. Low levels of bacteremia and endotoxins provides a stimulus for the systemic inflammatory response. In periodontitis, the interaction of lipopolysaccharide (LPS) from gram-negative bacteria with host cells initiates the secretion of cytokines and the expression of cell adhesion molecules in gingival tissue which leads to loss of alveolar bone and connective tissues supporting the teeth. In the management of chronic periodontitis, non surgical periodontal therapy (NSPT) which includes oral hygiene instruction (OHI), scaling and root planing, is administered to improve clinical parameters as well as controlling the bacterial count responsible in initiating the disease and the resultant inflammatory response. Success of the treatment can be analyzed when the clinical parameters, counts of the microbes is reduced and inflammatory response is controlled. Studies which have evaluated the microbiological and immunological response following NSPT clearly demonstrates an improvement in clinical parameters, reduction in inflammatory mediators present as well as a decrease in microbial count. OHI which includes tooth brushing and inter-dental cleaning is found beneficial in removing microbial plaque, thus, preventing periodontal diseases such as gingivitis and periodontitis. Studies have evaluated the role of OHI on clinical and immunological parameters and microbiological profiles of periodontal maintenance subjects, while none of them evaluated its role alone in the management of chronic periodontitis subjects. Therefore, the purpose of the following investigation was to compare the changes in the clinical parameters, inflammatory mediators as well as level and frequency of detection of periodontopathogens that take place after 3-months of NSPT versus OHI and to evaluate if clinical parameters have an effect on these inflammatory mediators and microbiological changes.

Periodontitis is a form of gum disease that affects many people in the world. Its traditional protocol of treatment includes oral hygiene instruction and dental scaling to remove debris, dental plaque and tartar in 4 weekly sections. There is an additional time-reduced option also usually cheaper. In this last one, all above described procedures are performed within 24 hours. However, up to now comparative effectiveness between these both types of treatment is not well understood. For, example it is not clear if patients treated in the shorter-time experienced more pain. Therefore, the present study used several parameters to clarify whether beneficial differences between these therapeutic protocols exist or not. In addition, aspects that could help clinicians' and patient's decisions such as experience of pain and anxiety related to dental treatment were also investigated. After receiving verbal and written explanations and signed the informed consent form 150 individuals (n=15/group) having the most common type of periodontitis in adults were randomly allocated to be treated in 4 weekly sections or within 24 hours. Oral hygiene instructions and dental debridement were performed alone or in conjunction with antimicrobial agents: a mouth rinse containing chlorhexidine or systemic azithromycin antibiotic tablets. The parameters measured at baseline, 3, 6 and 9 months after treatment were: indicators of inflammation, amount of oral debris and malodor; quantification of bacteria in plaque samples collected with paper points from teeth and tongue; amount of produced saliva and self-reported questionnaires to collect information about oral condition, daily activities, pain and anxiety related to dental treatment.

Chronic periodontitis (CP) is an infectious disease resulting in inflammation of the supporting structures of the teeth, progressive loss of bone loss and insertion. The aim of this study is to evaluate the effects of antimicrobial Photodynamic Therapy (aPDT) as adjuvant to periodontal surgery treatment (PST) in patients diagnosed with generalized severe chronic periodontitis (GSCP). Twenty patients with a clinical diagnosis of CP will be treated in a split-mouth design study to either aPDT associated with surgical access for scaling and root planning (SASRP) or SASRP only. aPDT will be performed by using a laser light source with 690 nm wavelength associated with a phenothiazine photosensitizer. The applications will occur in only one episodes. All patients will be monitored for 30 and 90 days after PST. Clinical assessment of plaque index, probing depth, clinical attachment level and bleeding on probing will be performed at baseline (pre-intervention period) and 30 and 90 days after the PST. Subgingival plaque samples will be collected (at baseline and 30 and 90 days after the PST) and the counts of 40 subgingival species will be determined using DNA-DNA checkerboard hybridization. Data obtained will be statistically analyzed.

The aim of this prospective interventional study is to verify the efficacy of smoking cessation on clinical and microbiological outcomes of non-surgical periodontal therapy of chronic periodontitis patients. Smokers willing to quit received periodontal treatment and concurrent smoking cessation therapy. Periodontal maintenance was performed every 3 months. A single calibrated examiner, blinded to smoking status, assessed periodontal clinical outcomes and applied a structured questionnaire in order to collect demographic and behavioural information. Further, expired carbon monoxide concentration were measured with a monoximeter. A pooled subgingival plaque sample was collected from the deepest periodontal pocket from each participant. The presence and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola were determined using (RT-PCR).

The purpose of this study is to determine whether ST266 will reduce pocket depth (PD) as an adjunctive to scaling and root planing (SRP) in subjects with moderate to severe periodontal disease.

The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planning with hand instruments in nonsurgical treatment of chronic periodontitis.
