Filter by:Periodontal disease is a chronic progressive state of inflammation pertaining to supporting tissues of the dentition that culminates in loss of the affected teeth. Currently, diagnosis and monitoring of periodontal disease progression is accomplished by performing a full-mouth clinical and radiological examination which is time-consuming and also requires elaborate infrastructure and equipment, which are not always available. Limitations of the conventional diagnostic techniques necessitate the development of point-of-care testing (POCT) which could serve as a rapid, feasible and affordable screening tool for periodontal disease.MIP-1α is a cysteine-cysteine (C-C) chemokine that is secreted by a variety of cells like macrophages, fibroblasts, epithelial cells and endothelial cells. They principally serve to recruit leukocytes like monocytes, T lymphocytes, natural killer cells, dendritic cells and granulocytes to the site of inflammation. Hence, the current study has a two fold aim; first, to determine the feasibility of MIP-1α as a periodontal disease biomarker; and second, to correlate the value of MIP-1α obtained from oral rinse sample with the periodontal disease severity.
Periodontitis is a major public health problem because it is widespread in the adult population. It leads to the irreversible destruction of the anchoring tissues of the teeth, and represents a modifiable risk factor for systemic inflammatory pathologies. This chronic inflammatory disease, which is associated with oral dysbiosis involving Porphyromonas gingivalis, is triggered by a permissive immune response. It is preceded by a reversible clinical phase, during which there is no bone resorption process: gingivitis. The understanding of the key mechanisms involved in the evolution from gingivitis to periodontitis, which will allow to early identify patient at risk of periodontitis, remain unclear at this time. Neutrophils are the main cells of inflammation present within the periodontal pockets. The excess of certain neutrophils or the alteration of their functions is associated with the triggering of periodontitis, whereas their activity, finely orchestrated, would be a key to periodontal homeostasis. It is likely that some periodontal bacteria, including P. gingivalis, but also products of matrix catabolism could deregulate the physiological functions of neutrophils towards pro-inflammatory and catabolic profiles. Moreover, to date, the differentiation and role of neutrophil subsets in periodontal homeostasis as well as in gingivitis and its evolution into periodontitis remain poorly studied. The investigators hypothesize that various subsets of neutrophils may play different roles during the development of periodontitis (evolution of gingivitis to periodontitis). The primary objective is to characterize neutrophil subtypes associated with periodontal destruction during periodontitis. Secondary objectives are : 1. Identify specific interactions of tissue-activated neutrophils with the matrix microenvironment during periodontitis 2. Identify specific interactions of tissue or oral (salivary) activated neutrophils with the oral microbiota during periodontitis 3. Identify specific oral (salivary) neutrophil subtypes in periodontal health, gingivitis and periodontitis 4. Evaluate the function, including pro-osteoclastogenic function, of oral neutrophils compared to blood neutrophils stimulated by infection
Bruxism is a multifaceted phenomenon that has been associated with several factors mediated by the central nervous system3. Bruxism is an umbrella term grouping different motor phenomenon. 'Bruxism is a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible. Bruxism has two distinct circadian manifestations: it can occur during sleep (indicated as sleep bruxism) or during wakefulness (indicated as awake bruxism5. Sleep bruxism is considered to be a putative exacerbating factor, rather than a causative factor of periodontal disease and night-guards have been used as a counter measure. Since the periodontium in sleep bruxism patients suffers from excessive occlusal force for long periods of time during sleep, the function of the periodontium in such patients may differ from that in patients without sleep bruxism. Awake bruxism is defined as masticatory muscle activity during wakefulness that is characterized by repetitive or sustained tooth contact and by bracing or thrusting of the mandible.Given the potential impact of abnormal forces on the periodontium, understanding the relationship between bruxism and periodontal disease is crucial for the prevention and management of these conditions. This study aims to explore the mechanisms by which bruxism affects the periodontium and to assess the impact of bruxism in the outcome of subgingival instrumentation for the management of Stage 2 and Stage 3 periodontitis.
Since 2018, the Chicago Classification of Periodontal Diseases and Conditions, has listed Down syndrome (DS)/trisomy 21 (T21) as a systemic disease with periodontal implications. Numerous studies report an increased prevalence and severity of periodontitis in DS/T21 individuals under the age of 35. Approximately 35% of adolescents with DS show early signs of alveolar bone loss. However, very few studies have examined the role of immune deficiency in DS/T21 patients in the pathogenesis of periodontitis. Indeed, periodontitis induced by bacterial plaque is virtually non-existent in the paediatric population, leaving the field to systemically-induced periodontitis. The investigators hypothesize that specific neutrophil phenotypes in DS/T21 patients are key to explaining the rapid progression to periodontitis. Investigator's primary objective is to characterize the different oral and blood neutrophil subtypes in DS/T21 children with gingival inflammation. Investigator's secondary objective is to assess the involvement of different neutrophil subtypes in early periodontitis in children with DS/T21.
Periodontitis is an immune-inflammatory disease affecting the supporting structures of the teeth. It is a disease of multifactorial etiology, with microbial, genetic, environmental and host factors involved, with the release of oxygen-free radicals by the inflammatory cells. Quercetin, have shown potential antimicrobial activity, lowering of inflammatory markers, cholesterol reduction and inhibiting bone loss. However, this data has largely been obtained from in vitro and animal studies, but data from human studies are limited.
The primary objective:To evaluate the efficacy of different administration protocols of human dental pulp mesenchymal stem cells for the treatment of chronic periodontitis patients. The secondary objective:To evaluate the safety of different administration protocols of human dental pulp mesenchymal stem cells for the treatment of chronic periodontitis patients. The exploratory objective:To investigate the effects of human dental pulp mesenchymal stem cells on biomarkers in gingival crevicular fluid in chronic periodontitis patients.
Platelet rich fibrin (PRF) has been widely used in regenerative dentistry since it provides plenty amount of growth factors that enhance wound healing and tissue regeneration. Platelet derived growth factor-BB (PDGF-BB) is a growth factor with essential functions such as regulation of cell migration, proliferation, and differentiation. This study aims to evaluate the efficacy of PRF in improving the clinical periodontal parameters and GCF level of PDGF-BB.
Background- The use of minimally invasive procedures has recently been advocated for the treatment of periodontitis, to minimize patient discomfort and maximize the healing potential. These techniques usually involve the use of magnification lenses or microscopes and small instruments which reduce the risk of tissue trauma compared with traditional instruments. Rationale- So far only descriptive data about the clinical effects of such procedure are available and comparative studies that would include other treatment alternatives are lacking. Therefore, the aim of this study is, on split-mouth model, to compare the number of diseased sites (defined by probing depth ˃ 4 mm and bleeding on probing) after conventional subgingival instrumentation and Minimally invasive nonsurgical periodontal therapy (MINST) with the usage of special mini instruments and magnifying loupes. Objectives- To compare sites that have residual probing depth and require further surgical intervention after undergoing the two treatment modalities. Methods- In this split mouth randomized controlled trial, Test group will undergo non surgical therapy under magnification and using special mini bladed instruments while the control group will undergo conventional subgingival instrumentation. Reevaluation will be at 6 weeks and 3 months. Expected outcomes- If both the groups differ in outcomes after therapy, MINST can be used to minimize the number of sites that require surgery and hence will reduce treatment costs and morbidity.
Background- In developing countries like India, seeking mental health care is still a taboo, and a lot of stigma is attached to consulting a psychiatric specialist or a counselor. This problem magnifies during postpartum period characterized by depressive symptoms in mothers indicating persistent low mood and feeling of worthlessness with easy fatigability, poor appetite, and sleep deprivation which leads to lack of interest in daily activities including oral health care. Rationale- Many studies have evaluated the periodontal status during pregnancy and its consequences but only few studies have been conducted evaluating the periodontal status during the postpartum period. None of the study has evaluated the association of Mental health and periodontitis during postpartum period. Objectives-To assess the Association between Periodontal status and Mental health in Postpartum women Methods- Periodontal Status and Mental health status (by Mental Health Inventory) will be assessed in Women during postpartum period (6-8 weeks- 6 months after delivery). Expected outcomes- Study of periodontal status during postpartum period may contribute in elucidating this interrelationship and helps to design better prevention strategies for women's mental health.
Untreated periodontal infection may result in transient bacteremia and toxaemia which may be the cause of adverse systemic events, leading to various systemic disorders. Amongst all the systemic diseases, cardiovascular disease has been recognized as a major systemic inflammatory condition that present similarities with periodontal disease. Increased systemic biomarkers of inflammation associated with periodontal disease have been interpreted as a mechanistic link between periodontitis and cardiovascular diseases. Genetic factors are also known to play a pivotal role in influencing the inflammatory and immune response. Genetic polymorphisms are alterations in the DNA sequence found in general population. Most forms of periodontitis represent a life-long account of interactions between the genome and the environment. The previous literature has stated a strong association of genetic polymorphisms in periodontitis and coronary artery diseases. Identifying these polymorphisms can potentially lead to a better understanding of the mechanisms modulating the expression of inflammatory mediators as well as provides potential therapeutic targets in the prevention of periodontal disease. Two such novel polymorphisms have gained attention recently, namely the Dickkopf-3 and complement factor H polymorphisms. Dickkopf-3 belongs to Dickkopf family of glycoproteins. Dickkopf-3 has been mainly investigated in oncology for its role as a tumor suppressor gene and as a therapeutic target in several types of human carcinomas. Recently, Dickkopf-3 gained attention as an emerging biomarker for cardiovascular and renal diseases. Dickkopf-3 has shown to play a role in pathophysiology of arterial wall thickening and abnormality implicated in atherosclerosis. However, genetic polymorphism of Dickkopf-3 rs11544814 and complement factor H rs10737680 its protein levels have never been investigated in subgingival plaque samples of periodontitis patients with coronary artery disease specifically before and after non-surgical therapy. This may further improve our understanding of the influence of this polymorphism on the above mentioned systemic diseases.
