RESUMO
Autoimmune diseases are group of disorders where an immune response is mounted against the self. The prevalence and burden of this well established and recognised entity is on the rise. Irrespective of being a systemic or organ specific autoimmune disorder, the common underlying mechanism of action, is the imbalance in immune system resulting in loss of tolerance to self-antigens. The oral cavity is no alien to these disorders or to their influences. Pemphigus group of lesions, systemic lupus erythematosus, psoriasis and even Sjogren's syndrome are some of the established autoimmune disorders with prominent oral manifestations. Though these diseases are well documented and enumerated, however addressing them is where the dilemma lies. Science, research and discoveries are a crucial part of medical discipline which help in looking beyond the horizon. With the introduction of selective targeted immunotherapies for autoimmune diseases as a treatment modality either in solitary or in combination with the conventional immunosuppressive treatments, are emerging as a promising elixir for patients enduring them. However, being unique, exploration of these biologics from its inception, to its mechanism of action, recognition of its application and evaluation of its safety norms are equally vital. Therefore, this review aims to provide a comprehensive particular on the novel biologics, the immunotherapies in autoimmune disorders targeting the different cells, their receptors or cytokines of the immune system.
RESUMO
Oral biofilm, a tribulation encountered on a general basis is known to associate and contribute to many oral and systemic diseases. Eradication of these biofilms is a primary step in treatment of the underlying malady. Management of a biofilm is governed by various factors: the microenvironment within a biofilm, bond between the adhered surface and the biofilm, location of the biofilm, access to the biofilm for removal. Though annihilation is the priority, the mode of approach to achieve the same is equally important, because biofilm's heterogenic nature and location govern the strategical treatment required. Literature supports that the consequences of oral biofilms is not restricted to its home ground, but disseminated to other systems of the body. This contemplates us to procure knowledge on its development, structure and progression to aim its eradication. Therefore, this review attempts to recognize the type of biofilm based on location and enumerate all the possible chemical modes of management for the specific type of oral biofilms encountered. In addition, to the traditional strategies prescribed or administered, newer approaches which are gaining popularity due to their ease and efficiency are also addressed. Frontiers in the above field, under investigation and promising in near future are also compiled. Thus, the present review aims to provide a comprehensive elucidation of chemical management of oral biofilms, both the conventional and novel approaches under investigation.
