Filter by:By promoting the cellular activities, it has been shown that the low-level laser therapy (LLLT) is able to accelerate the wound healing, reduce gingival inflammation, relief the discomfort, and serve as an adjunct to the traditional periodontal treatment. As an economic and environmental friendly alternative of the laser, the effect of 660 nm light-emitting diodes (LED) light in facilitating the healing of the oral soft and hard tissue wounds in vivo has been also demonstrated in our previous studies. The aim of this study is to further investigate the feasibility of 660 nm LED light appliance in support of the non-surgical periodontal therapy (NSPT). The LED light appliance will be fabricated by JETTS Technology Co., and the adjunct effect of the LED light on the treatment of periodontitis will be evaluated. Patients with at least one periodontitis-involved teeth in three quadrants will be recruited, and three protocols of LED light irradiation, including LED light irradiation from initial clinical assessment (T0) until the completion of scaling and root planning (T1) (LED01), LED light irradiation from T1 until re-evaluation (T2) (LED02), and no LED light irradiation (control treatment), will be randomly assigned to individual quadrant during the non-surgical periodontal therapy. Clinical parameters will be assessed at T0 and T2, and biomarkers, including IL-1b and MMP-8, from gingival crevicular fluid will be assessed at T0, T1, and T2. It is expected that 660 nm LED light irradiation,regardless of the timing of irradiation, significantly reduce the discomfort of the periodontal treatment, gingival inflammation, and accelerate healing, and hopefully a prototype of LED light appliance for the periodontal treatment could be developed.
Hidradenitis suppurativa or Verneuil's disease (HS) is a neglected and often overlooked chronic inflammatory skin disease. Nevertheless, it is frequent (1% of the general population) and deeply affects quality of life in patients with moderate and severe forms of HS. This disease is characterized by the occurrence of deep, recurrent and painful nodules, progressing to abscess formation and suppuration. It is usually localized in the axillary, inguinal and anogenital areas. The pathogenesis of HS remains partly unknown but is probably multifactorial (inflammatory, genetic, infectious, etc.) and related to many risk factors (mostly smoking and obesity). An association can be found with other inflammatory diseases such as gastrointestinal and rheumatic diseases like Crohn's disease and spondylo-arthritis respectively. Periodontal diseases are a heterogeneous group of infectious diseases with an inflammatory component. Their clinical expression results in more or less rapid destruction of tooth supporting tissues. Without treatment, these lesions may progress ultimately to tooth exfoliation, the rate of disease progression being unevenly distributed in the population. Various epidemiological studies in France indicate that 12 to 13% of middle-aged adults have severe periodontal damage. In addition, a recent study shows that while 50% of adults in France are suffering from severe attachment loss, generalized forms are rare and about 10% of individuals seem to require special care. The bacterial factor is the main etiological factor of these diseases but their progression depends primarily on the host immune response and on modifying factors (genetic, systemic, environmental and behavioural). Some of these factors are identified such as uncontrolled diabetes, smoking, stress, etc.. Finally, it is well established that periodontal disease may also trigger the development of some systemic diseases such as diabetes. Thus, many common etiopathogenic factors between HS and periodontal diseases such as inflammatory components and tobacco are found. This is corroborated by observations collected from some patients with HS complaining of oral pain exacerbated during acute flares of HS. Hence the aim of this project is to clarify existing potential association between Hidradenitis suppurativa and periodontal diseases using a multicenter cross-sectional descriptive clinical approach. One hundred patients with HS will be included in the departments of dermatology at the University Hospital in Reims and at the Pasteur Institute in Paris. They will be compared with one hundred patients without HS recruited from "general practice" consultations in the departments of Odontology at the University Hospital in Reims and at Bretonneau Hospital in Paris. The severity of HS will be assessed with Hurley's score by the dermatologist. The periodontal status will be evaluated with clinical indices and radiographical parameters by a periodontist according to the "Armitage" classification of periodontal disease and to CDC-AA case definitions updated in 2012. Meanwhile, human saliva is a biological fluid taken to reflect the health status of an individual and is or may be used for diagnosis and prognosis of some oral cancers, some systemic diseases (type 2 diabetes, sarcoidosis, etc.) or periodontal diseases. The saliva will be collected and analysed by proteomics and metabolomics techniques in order to identify biomarkers for diagnosis and prognostic of HS associated or not to periodontal diseases. These unpublished works could demonstrate a predisposition to develop periodontal disease in a subgroup of HS patients and help to unravel new etiopathogenic mechanisms common to both diseases as well as ultimately lead to early periodontal management in order to avoid disease progression and tooth losses.
This study will evaluate periodontal and systemic parameters of a cohort of chronic kidney disease (stage 5) patients, before and three months after non-surgical periodontal treatment. It does not consider a control group.
this will be an RCT. to determine if non-surgical treatment for periodontitis can improve the disease activity score in 28 joints of rheumatoid arthritis in an African setting. Rheumatoid arthritis patients with periodontal disease will be randomised into an immediate intervention arm and a delayed intervention arm and both groups will be followed for two three monthly periods
Epigenetics has produced a high impact in biomedical research and is providing new biomarkers for the diagnosis and prognosis of diseases. In addition, epigenetics is also contributing to analyze the molecular causes underlying diseases, even so periodontal diseases as it has been recently reviewed. In this regard, changes in the methylation of genes codifying for pro-inflammatory and anti-inflammatory cytokines has been previously reported. miRNAs are very promising biomolecules to be used as biomarkers because miRNAs act as signaling molecules and participate in many biological processes, such as cellular development, differentiation, and apoptosis. The high stability of circulating miRNAs in the RNase-rich environment of the bloodstream and also in different biospecimens used in clinical routine, make these biomolecules an optimal source of candidate biomarkers. In fact, miRNAs have demonstrated their value as dynamic biomarkers in a wide variety of human diseases. Therefore, miRNAs can be used for the monitoring of periodontal disease. The objective of this research is to analyze the levels of bone remodeling RANKL / OPG biomolecular markers, and the epigenetic regulation of these proteins to identify promising biomarkers of periodontal disease. Material and Methods. Levels of RANKL and OPG will be measured in the gingival crevicular fluid (GCF) to assess the state of bone. These samples will be sent to the lab for quantification by ELISA method. Furthermore, new epigenetic biomarkers based on the identification of high stable microRNAs will be identified by qRT-PCR in GCF as feasible tools for diagnosis and monitoring of wide range of disease, including periodontal disease.
This study will seek to evaluate the predictability and efficacy of a Computer Aided Design-Computer Aided Manufacturing and additively manufactured polycaprolactone and hydroxyapatite scaffolds in these defects compared to traditional guided tissue regeneration. 40 gingival recessions associated with interproximal tissue deficiency will be divided into two groups: control group (autogenous bone + collagen membrane; n = 20) and test group (autogenous bone + scaffold; n = 20).
Direct Oral Anticoagulants were recently approved for medical treatment of several condition such as, non valvular atrial fibrillation, deep venous thrombosis, and others, substituting sometimes the conventional oral anticoagulants. The aim of the present study is to observe the possible difference in intra-operative and post-operative bleeding events for periodontal debridement.
Dental calculus is a calcified deposits firmly attached to teeth and implants surfaces. Dental calculus is strongly associated with periodontitis and considered to have indirect role in the pathogenesis of periodontal diseases. Dental calculus composed primarily of calcium phosphate mineral salts originated in the saliva covered by unmineralized bacterial layer. Composition of calculus varies from person to person and influenced by numerous variables such as: age, gender systemic disease and ethnic background. Nephrolithiasis (kidney stones) are composed of insoluble salts of constituents of the forming urine. The most two frequent stone types are: Calcium oxalate (with a frequency of 15% -35%) and Calcium phosphate (5% -20%). The prevalence of kidney stones varies with race, sex, and geographic location. In the United States for men, kidney stone rates vary between 4%-9%, and for women, kidney stone rates range between 2%-4%. Previous studies dealt with the connection between sialolithiasis and nephrolithiasis were inconclusive. To the authors' best knowledge no studies were done to examine the associations between nephrolithiasis and dental calculus. Thus, the aim of this study is to compare the mineral composition of both dental calculus and nephrolithiasis and determine whether nephrolithiasis composition may be linked to the periodontal status.
This study evaluated the periodontal status of patients suffering from eating disorders (anorexia nervosa and bulimia nervosa). The work hypothesis is that eating disorder patients have a higher risk for periodontal diseases than non-eating disorder subjects.
This study is to verify the efficacy of tobacco cessation in patients with oral diseases; periodontitis, dental implant and oral mucosal diseases by a multicenter prospective trial. Tobacco cessation intervention is implemented for 12 weeks. During the tobacco cessation intervention for the subjects, attending doctors implement standard treatments for their oral diseases. Improvement of each disease is evaluated between smoking cessation intervention group and non-cessation intervention group.
