Systemp desensitizer is a one-bottle liquid that is recommended for the chairside treatment of sensitive, exposed dentin. Ivoclar Vivadent indicates that it is appropriate for use under most direct restorations as well as before cementing temporary or permanent restorations. The product, an aqueous solution of 35% polyethylene glycol dimethacrylate and 5% glutaraldehyde, is purported to reduce sensitivity by sealing dentin tubules. Systemp.desensitizer is applied by brushing it onto tooth structure for 10 seconds. Excess liquid is then gently dispersed into a thin layer using compressed air. It is available in bottle form or in unit-dose capsules that have an attached disposable applicator. The Dental Investigation Service evaluated the unit-dose form.
Systemp Desensitizer was generally found to be effective at reducing sensitivity by the clinical users. They found it fast and easy to apply, especially because it does not require light activation. Evaluators particularly appreciated its unit-dose packaging, which enhances infection control. Systemp is considerably less expensive than two other popular desensitizers. It comes with a helpful illustrated instruction card, lot numbers and expiration dates are printed on each unit-dose package, and a recommended storage temperature range is listed on the box. A Material Safety Data Sheet is provided with the product.
Product instructions are vague about how to use it during adhesive bonding procedures and do not specifically state how Systemp Desensitizer may affect a range of dental materials, including impression materials. The contradictions and omissions of the instructions are a significant problem with this product. In fact, they leave the user without clear guidance as to the specific materials with which the product can and can not be used. Another major disadvantage of Systemp Desensitizer is the fact that its instructions do not state that it can be used to treat teeth with hypersensitive exposed cervical dentin, which is perhaps the most common reason for purchasing and using a desensitizer.
