ClinConnect Summary

The Lithium Disilicate Crowns Study is a clinical trial that aims to evaluate the effectiveness of special dental crowns made from a material called lithium disilicate. These crowns are designed to restore teeth that have decay or damage, specifically on the upper or lower premolars and molars. The trial will compare two different methods of attaching these crowns to the teeth—using either a dual-curing adhesive or a self-adhesive material. This study is not yet recruiting participants.

To be eligible for this trial, participants should be at least 18 years old and have at least one tooth that needs restoration due to decay or an old restoration that isn’t working well. The tooth must still be alive and not causing any pain. However, individuals with certain conditions, such as teeth that have previously undergone root canal treatment or those who are pregnant or breastfeeding, cannot participate. If you decide to join, you can expect to have one or two crowns placed on your teeth during the study, with follow-up appointments to ensure everything is healing properly. This trial is an opportunity to receive advanced dental care while contributing to important research.
