The main objective of this study i s to compar e chelation values of 17% self developed & commerciall y available root canal Lubricants or dental chelating gel s as well as to see whether their performance depends on the chelation value or not. The Chelating agent bounds Ca 2+ ions of the smear layer & th e extent of chelate formation between chelating agent and metal ion is nothing but Chelation Value. S odium carbonate indicator method is used for determinations of chelation value. Commercially available gel incorporated in this study wa s File Rite which h as little bit higher chelation value. Self developed chelating gel or root canal lubricants have comparatively lower chelation value. Root canal lubricants having higher chelation value should perform better in shaping & cleaning of root canal better . Howe ver because of slight difference in chelation value of self developed & commercially available gel, no significant difference was found out as root canal lubricants , when applied in root canal for 5 minutes.
