Why is it important?

In market today, most of the dental products are from developed countries. Developing countries are also producing products of native origin and trying to be at par with international standards. Many studies have been conducted on the dimensional stability of the international products from developed countries after disinfection but evaluation of products from developing countries has not been carried out extensively to see their stability.Irreversible hydrocolloid is one of the impression materials frequently used in the making of a fixed prosthesis. Alginate impressions are used extensively in dentistry for making diagnostic casts, check impressions and making impressions for provisional crowns. The other material taken up in this study is addition silicone which is one of the most accurate impression materials. In this study, the effect of commercially available disinfectants like 2% glutaraldehyde, 5.25% sodium hypochlorite and the ultraviolet rays on the dimensional stability of commonly available and extensively used irreversible hydrocolloid and addition silicone from international brands and the same materials from developing countries was studied and the results were recorded and compared.
