# Histogenetics in Teaching the Complexity of Developmental Biology to Dental Students: A Study Merging Traditional and Current Approaches

## TL;DR

This study shows that combining traditional and modern teaching methods improves dental students' understanding of developmental biology.

## Contribution

A blended teaching approach for histogenetics that integrates traditional and innovative methods to enhance student learning.

## Key findings

- Students reported high engagement and perceived learning with the merged teaching approach.
- The method was rated as clinically relevant and easy to understand by most participants.
- Positive feedback was received across self-evaluation, resources, and teaching method domains.

## Abstract

Background: Dental students need to qualify with a clear understanding of the continuum of biological development from the molecular (genetic, epigenetic and environmental interactions) to the cellular (morphogenesis and differentiation) to the emergence of the mature tissue or organ. Histogenetics provides a core component for this understanding. The aim of this study is to investigate whether a merged approach, combining traditional and recent methods, can enhance the teaching of histogenetics to dental students. Methods: This study blended traditional (lectures, drawings, microscopy) and recent approaches (flipped classroom elements, virtual microscopy, group-based poster construction, and interactive quiz-based discussion) to enhance student engagement and perceived learning in oral histogenetics. The intervention was delivered to master-level dental students across six core oral histogenetics topics. Teaching followed a structured three-phase model: Prepare (digital lectures and short microscopy-introduction videos); Engage (microscopy session and group-based poster creation); and Test and Discuss (teacher-led quizzing and discussion). Student perceptions were evaluated through an electronically distributed 17-item questionnaire at the end of the course. Items were grouped into self-evaluation, resources, and teaching method domains and rated on a five-point Likert scale. Results: A total of 45 of 51 students responded (88%). Across all domains, positive perceptions (Agree/Strongly Agree) predominated (p < 0.001). Self-evaluation items showed strong agreement for attendance and group contribution, with more variability in preparation time and motivation. Resources were rated highly, although the accessibility of physical guidance showed more mixed responses. The merged teaching method received strong endorsement, with students reporting engagement, enjoyment, ease of understanding, and clear emphasis on clinical relevance. Conclusions: The merged approach was perceived as pedagogically valuable and clinically meaningful by the students and appears to enhance perceived engagement, clarity, and relevance in oral histogenetics teaching. These findings support the adoption of blended, student-active methodologies to strengthen comprehension and promote clinically meaningful learning in oral histology.
