Evaluating the Role of Analogies in Biochemistry Education: Lessons Learned From Pre‐ and Post‐Pandemic Dental Student Perceptions

Journal of Dental Education, EarlyView.
ABSTRACT Biochemistry forms the foundation for understanding biomolecules and molecular processes crucial to dental and oral biology. However, it is often perceived as a challenging subject for dental students with diverse educational backgrounds. Analogies are a pedagogical tool that helps explain new and abstract concepts in biochemistry.

Biomaterial used to counteract ridge reduction following the removal of adjacent teeth: A randomized controlled multicenter study

Journal of Periodontology, EarlyView.
Abstract Background Alveolar ridge resorption (ARP) is a well‐recognized consequence of tooth extraction, and multiple adjacent extractions may lead to greater ridge reduction than single‐tooth extractions. This multicenter randomized controlled trial aimed to assess ridge remodeling after removing 2 adjacent teeth and whether socket grafting with ...
