Prime Dental Retra Liquid Astringent Solution 30ml is an effective agent for gingival retraction during dental procedures, particularly for crown and bridge work. Composed of aqueous aluminum chloride, it offers excellent astringent properties without retarding the setting of silicone impression materials, unlike other retraction agents. It is designed to be used in conjunction with retraction cords, enhancing their effectiveness when dipped into the solution for two minutes. The solution is non-staining, ensuring no unwanted marks on fabrics. It should be applied with care to avoid unnecessary contact with soft tissues where retraction is not required. After use, it is important to wash the area thoroughly before taking final impressions. This solution is packaged in a 30ml bottle and should be stored in a cool, dry place.
