Abstract:
This article is an attempt to review all the articles available in English language on tissue conditioner in theliterature through 1996-2012. A detailed search in the National Library of Medicine's PubMed database, Google search and Science Direct to include all studies and reviews published in English language. This paper tries to give an overview of the composition, properties and uses of tissue conditioning materials.

Introduction:
In the present day scenario a lot of improvement in the field of medicine and research which has increased the life expectancy of the geriatric patients. Increased life expectancy combined with improved socialization has made people conscious about their appearance and performance in the society. There is a greater need for preservation of the remaining teeth and also for replacement of the lost teeth by an artificial substitute. The dentures are worn by the elderly for a time longer than needed with a minimum rest given to the bearing tissues.The increased wearing of dentures leads to irritation of the soft tissues, depriving it from blood supply and also leading to resorption of the supporting bony foundation. As a consequence, the dentures tend to loosen demanding for the use of materials like tissue conditioners and denture adhesives to improve retention. Denture liner use in dentistry is not new and is known for many years now1.Resilient liners which were used previously were natural rubbers. In the year 1945,the first synthetic resin m ad e o f p la s t i ci ze d p oly vi ny l re si n s were developed and the silicone rubbers followed in 19582.
Uses of denture reliners:
Denture reliners find several uses in the specialty of prosthodontics. They are used to improve fit of ill fitting dentures, to prevent traumatic damage to the mucosa, as a cushion between denture bearing mucosa and denture, to retain over denture bar attachments, to retain extra oral prosthesis, to distribute occlusal forces, to increase serviceable life of prosthesis, to replace the fitting surface of conventional hard dentures, to relieve mucosal pain under hard dentures, improves the rhythm of chewing strokes, it also compensates for the volumetric shrinkage of acrylic resin .
