NCT07282977
Efficacy of Three Gingival Displacement Methods
The goal of this clinical trial is to find the best gingival displacement method for taking impressions of artificial full crowns with subgingival margins. The main question it aims to answer is: Which of the three common gingival displacement methods works best? Researchers will compare three methods: gingival retraction cord, gingival retraction paste, and gingival retraction cord + hemostatic gel, to see which is optimal. Participants will: Receive one of the three gingival displacement treatments during impression taking. Fill out a VAS form to rate their pain.

Clinical Trial of Modified Endocrown and Personalized Post-core and Crown for Large-area Tooth Defects After Root Canal Treatment
This study intends to adopt a multicenter, randomized controlled, single-blind, non-inferiority clinical trial design. 246 premolars that meet the inclusion criteria after complete root canal treatment will be selected from the clinical practice and randomly divided into two groups. One group will be restored with the modified endocrown, and the other group will be restored with personalized post and core combined with full crown. Follow-up visits were conducted at 6 months, 1 year and 2 years after the operation respectively. Through clinical and imaging examinations, the survival rates of the two different restorations were evaluated and used as the main evaluation indicators to fill the gap in efficacy data of the modified endocrown in clinical applications, providing a strong evidence-based medical basis for subsequent restoration improvement and standardized application.

Prevalence of Long-term Dental Effects of Chemotherapy in Childhood Cancer Survivors Diagnosed With Cancer Before the Age of 10
To date, there are no methods for assessing the risk of oral developmental defects that could predict long-term adverse effects in childhood cancer survivors. Having such a method at our disposal would enable us to better assess the risk to develop those defects and will help us provide new prevention and treatment strategies to ensure a healthy oral development. The aims of this study are : * Assess the caries risk in childhood cancer survivors compared with a control group. * Assess the dental development defects risk in childhood cancer survivors compared with a control group.
