Microleakage study of three adhesive systems

Brazilian Dental Journal, 2004
The purpose of this in vitro study was to evaluate the efficacy of three hydrophilic dentin adhesive systems to reduce class II restoration microleakage. A total of 60 human molar teeth were used in which two box cavities were made on the distal and mesial surfaces, with a cervical margin in dentin. These cavities were randomly divided into 3 groups (n

Biological Matrix‐Assisted Apexification: A Case Report Using PRF and MTA in Immature Necrotic Teeth

Case Reports in Dentistry, Volume 2026, Issue 1, 2026.
It is challenging to treat an infected nonvital young permanent tooth endodontically because there is a lack of natural apical constriction. In order for the obturating material to be condensed, an apical barrier must be induced. Calcium hydroxide has historically been used to induce apexification.
