What is a disadvantage of using resin as a cement?

Using resin as a cement can indeed lead to microleakage over time, which is a significant disadvantage. Microleakage refers to the small gaps that can form between the tooth structure and the restoration, allowing bacteria, fluids, and other substances to seep in. This can contribute to secondary caries (cavities that occur under or near a dental restoration) and can compromise the longevity and health of the tooth.

While resin cements are often chosen for their aesthetic qualities and good bonding properties, if proper attention is not given to the application and curing process, microleakage risks increase. Factors such as inadequate bonding, improper light-curing technique, or moisture contamination during placement can exacerbate this issue.

This concern highlights the importance of technique and material selection in dental procedures, as optimal outcomes rely not just on the materials used but also on the practitioner’s skill and adherence to best practices.
