Contemporary Dentin Bonding Agents-A Review

[Year:2018] [Month:July-December] [Volume:8] [Number:2] [Pages:7] [Pages No:13 - 19]

Keywords: Dentin bonding agent, etch and rinse, wet bonding

PDF  |  DOI: 10.5005/jsd-8-2-13  |  Open Access |  How to cite  | 

Abstract

The purpose of contemporary dentin bonding agent is to know or understand the clinical effectiveness of contemporary resin-based dentin bonding agents primarily focusing on the longevity of restoration. Despite the significant improvements of adhesive systems, the bonded interface remains the weakest area of tooth-colored restorations. The most important reasons for the failure of adhesive restorations with earlier adhesives are the loss of retention and the deficient marginal adaptation. However, the introduction of reliable adhesive restorative materials has subsequently reduced the need for extensive tooth preparation. Dentin bonding has evolved from no-etch to total-etch to self-etch systems. The development of self-etching primer adhesive systems has greatly simplified resin bonding procedures, as a separate etching step is no longer required. There is much interest and activity nowadays with dentin bonding agents. More focus has been laid upon conservative approach of tooth preparation. Therefore, introduction of adhesive restorative materials has reduced the need for an extensive tooth preparation. Modern dental bonding systems come as a “three-step system”, where the etchant, primer, and adhesive are applied sequentially; as a “two-step system”, where the etchant and the primer are combined for simultaneous application; and as a “one-step system”, where all the components should be premixed and applied in a single application (so-called seventh generation of bonding agents So, now the newer generations of bonding agents, self-etch, total etch and their mechanisms and their inner microscopic changes are explained in detail in the forthcoming pages.

Role of Immunology in Periodontal Disease: A Brief Review

[Year:2018] [Month:July-December] [Volume:8] [Number:2] [Pages:4] [Pages No:25 - 28]

Keywords: Immunology, Periodontitis, Pathogens, Cytokines, Antibodies

PDF  |  DOI: 10.5005/jsd-8-2-25  |  Open Access |  How to cite  | 

Abstract

Periodontitis is a highly complex and multifactorial disease. In recent years, researchers began to focus on bacterial-host interactions. It had been recognized that though the bacteria present in plaque initiates the periodontal inflammation, the host response to these pathogens equally matters in the progression of the disease. Therefore, the severity of this disease is due to a variety of factors, including the presence of periodontopathic bacteria, high levels of proinflammatory mediators and low levels of antiinflammatory mediators. However, the immune response initiated by periodontal disease seems to be much broader. This review attempts to enlighten the various immune mechanisms involved in periodontal disease initiation and progression.

Abstract

Matrix metallo proteinases (MMP) are zinc dependent endopeptitases. The role of MMP have been implicated in various physiological and pathological process including oraganogenesis, inflammation, vascular disease, wound healing, auto immune disease and cancer progression. Several MMPs was over expressed in head and neck squamous cell carcinoma (HNSCC) and the MMP found to have correlating with cell proliferation, angiogenesis, invasion, and metastasis. Epithelial–mesenchymal interactions involving cell–cell, cell–Extra cellular matrix (ECM), multistep process of carcinogenesis. ECM remodelling in tumor progression is mediated by MMPs. MMP 1,2,3,7,8,9,10,11,13, and 19 are most over expressed in HNSCC. The role of MMP 11(ST-3) in human breast carcinoma, ovarian cancer are well established whereas the expression of role of MMP 11 in oral squamous cell carcinoma (OSCC) gives varied observations. Hence the current review is aimed to various studies involved the immunohistochemical expression of MMP 11 in OSCC.

Role of Dna Repair Pathways in Aging- A Review

[Year:2018] [Month:July-December] [Volume:8] [Number:2] [Pages:3] [Pages No:38 - 40]

Keywords: DNA, Aging, Repair pathways

PDF  |  DOI: 10.5005/jsd-8-2-38  |  Open Access |  How to cite  | 

Abstract

Aging is a process where decrease of function occurs followed by DNA damage. DNA replication or transcription are affected because of structural damage to DNA, which leads to alteration or elimination of fundamental cellular process. To overcome this defect cell develop certain repair mechanisms. They are Base Excision Repair, mismatch repair, nucleotide excision repair, and double-strand break repair, homologous recombination, non-homologous end joining. Cancer cells can have increased rate of proliferation capacity, reduced apoptosis and increased capacity to invade basement membrane and metastasize. Because of genomic instability of cancer cell they easily break and reform chromosome and stimulate fusion of new oncogene and tumor suppressor gene are inactivated. To overcome this cancer cells should have capacity to withstand DNA damage.

Microbiological Profile of Chronic and Aggressive Periodontitis- A Review

[Year:2018] [Month:July-December] [Volume:8] [Number:2] [Pages:6] [Pages No:41 - 46]

Keywords: Chronic periodontitis, Aggressive periodontitis, Microbiology, Periodontitis

PDF  |  DOI: 10.5005/jsd-8-2-41  |  Open Access |  How to cite  | 

Abstract

Periodontitis is an microbial oral infection associated with the destruction of gingiva, cementum, periodontium and alveolar bone process. Periodontitis is broadly classified into chronic and aggressive forms. Both are distinguished in terms of microbiology, immunology, genetic influences and clinical presentation. The etiology of periodontitis would be because of accumulation of bacterial plaque, harbouring variety of pathogenic bacteria termed as periopathogens or periodontopathogens. The periopathogens ivolved in periodontitis are anaerobic bacteria such as Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum and Aggregatibacter actinomycetemcomitans. The microbiota of subgingival plaque contains more than 500 species of bacteria, nevertheless research has shown that Porphyromonas gingivalis, a Gram negative anaerobic bacterium, is the etiological agent which contributes to chronic periodontitis and is considered the keystone. Aggressive periodontitis is also influenced by microbiological, genetic, and host factors. The a comparative microbial profile between the two forms of periodontitis with the microbiological aspects of chronic and aggressive periodontitis can be explained in detail in this article.

Abstract

Oral and systemic infections are posing crucial and overwhelming problems to the individuals. Inflammation has been found to play a vital role in the pathogenesis of various oral and systemic diseases such as gingivitis, periodontitis, cardiovascular diseases, atherosclerosis, cerebrovascular ischemia, preeclampsia etc. Hence it is essential to be aware of the existing disease, careful identification of the etiological factors and diagnosis, treatment and regular follow up. Once inflammation is triggered, within few hours, a group of diverse proteins termed as acute phase proteins are synthesized by the liver and excreted into circulation as a host defense and adaptive response which is termed as acute phase response. These proteins serve as inflammatory markers and measurement of these help in identifying the status of the underlying infection.

Genetic Aspects of Chronic and Aggressive Periodontitis

[Year:2018] [Month:July-December] [Volume:8] [Number:2] [Pages:8] [Pages No:61 - 68]

Keywords: Gene, Aggressive Periodontitis, Chronic Periodontitis, Polymorphism

PDF  |  DOI: 10.5005/jsd-8-2-61  |  Open Access |  How to cite  | 

Abstract

Evidence suggests that there is some genetic basis for the periodontal diseases. The molecular abnormality and its genetic inheritance has been established in some cases of generalized aggressive periodontitis. Family studies indicates that this disorder is transmitted by autosomal recessive genes. Recent evidence also suggests that susceptibility to periodontal disease may be related in part to genetically determined immune responsiveness to bacteria. Although specific genetic risk factors have not been identified for the chronic periodontitis, recent studies indicate that there is significant genetic variance in the population. More precise definitions of disease phenotypes will facilitate future genetic epidemiologic studies of the periodontal diseases.
