DANB's Restorative Functions - Additional Info Sample Questions

Which of the following materials contains an organic solvent which should not be placed under a composite resin? 

Correct Answer:
resin varnish


resin varnish, also known as copal varnish, is a dental material that primarily serves as a protective barrier between dentin and restorative materials in dental procedures. it is composed of polyurethane polymers that are dissolved or suspended in an organic solvent. the role of the organic solvent in resin varnish is to facilitate the application and adhesion of the varnish to the tooth structure.

however, when it comes to using resin varnish under composite resins, there are significant compatibility issues that must be considered. composite resins are widely used in dentistry for restorative procedures due to their aesthetic appeal and durability. these resins typically polymerize (harden) through a chemical reaction that can be inhibited by the presence of certain substances, including organic solvents.

the organic solvent in resin varnish can interfere with the polymerization process of composite resins. this can result in inadequate curing of the composite material, leading to weaknesses in the restoration, reduced bond strength, and potentially shorter longevity of the filling or restoration. furthermore, the solvent can compromise the integrity of the bond between the resin composite and the tooth structure, increasing the risk of microleakage, which can lead to secondary caries and post-operative sensitivity.

in contrast, other materials listed such as fluoride varnish, calcium hydroxide, and acid etchant do not contain organic solvents that interfere with the curing of composite resins. fluoride varnish is used to enhance tooth remineralization and reduce sensitivity; calcium hydroxide serves as a protective liner or pulp-capping agent with antibacterial properties and promotes the formation of secondary dentin; acid etchant is used to roughen the tooth surface to improve the bonding of the composite resin.

in conclusion, due to the incompatibility of resin varnish with composite resins owing to its organic solvent content, it should not be used as an underlayer for composite resin restorations. instead, other compatible materials should be considered to ensure the longevity and effectiveness of the dental restoration.
