What is one of the main characteristics of ZOE temporary cement?

ZOE (zinc oxide-eugenol) temporary cement is known for its sedative qualities, which is one of its primary characteristics. The eugenol component in ZOE is effective in soothing pulpal discomfort, making it particularly beneficial for use in temporary restorations. This property allows it to provide relief for patients who may be experiencing sensitivity or inflammation in the dental pulp, making it a preferred choice in situations where the tooth may be susceptible to irritation from other materials.

While ZOE does provide some level of retention, it is not considered high retention compared to some other dental cements. It is primarily used for temporary applications rather than permanent crowns, which are typically secured with stronger, more retentive materials. Additionally, while ZOE generally has low toxicity, the term "non-toxic for all patients" can be misleading, as individual reactions may vary, and it could cause allergic reactions or sensitivities in some patients. Therefore, the sedative qualities of ZOE are what makes it especially valuable in dental practice.
