Dentoalveolar surgery education in Chinese undergraduate dental schools: a national survey of curriculum structure, simulation training and assessment
This national survey of 49 Chinese dental schools reveals that while dentoalveolar surgery education has established a framework centered on tooth extraction and local anesthesia, it faces significant challenges including a lack of course independence, inconsistent teaching hours, insufficient training in complex procedures, limited adoption of interactive digital tools, and an overreliance on theoretical assessment.

Imagine dental schools in China as a massive network of 49 different cooking schools. The researchers wanted to know: How are these schools teaching their students the most basic, essential skill of all—how to safely take a tooth out and numb the area?
They sent out a survey to see if the "recipe" for teaching this skill was the same everywhere or if every school was doing it their own way. Here is what they found, broken down simply:
1. The "Main Dish" vs. The "Side Dish"
In most of these schools, "tooth extraction" isn't taught as its own main class. Instead, it's like a single chapter inside a giant textbook called "Oral and Maxillofacial Surgery."
- The Analogy: Imagine trying to learn how to bake a perfect cake, but the recipe is just one small section inside a 500-page book about "Baking and Cooking." You get the cake recipe, but you also have to wade through chapters on bread, soups, and roasting meats.
- The Reality: 96% of schools do it this way. Only 2 schools treat tooth extraction as its own dedicated class. The authors worry that when it's just a "side dish" in a big course, students might not get enough time to really master the tricky parts.
2. The Timing: The "Senior Year" Rush
Most schools wait until the fourth year of a five-year program to teach this.
- The Analogy: It's like waiting until your final year of driver's education to finally sit behind the wheel and learn how to park.
- The Reality: While this happens after students have learned the basics, the authors suggest that waiting this long might be too late. They argue students should start getting familiar with the tools and concepts much earlier, like learning to hold a steering wheel in the first year, rather than just reading about it.
3. The Classroom: Books vs. Practice
The schools try to balance "theory" (reading and listening) with "practice" (doing).
- The Balance: Most schools spend about 10 to 20 hours on theory and a similar amount on practice.
- The Tools:
- Videos & Animations: These are the stars of the show. Almost every school uses videos to show students how to hold the tools or where to inject the numbing medicine.
- Virtual Reality (VR): This is the "missing link." Very few schools use high-tech, interactive VR simulators. It's like having a flight simulator for pilots; most schools are still using static pictures instead of a machine that lets students "fly" (or extract) in a safe, digital environment.
4. The Practice Kitchen: What Are They Actually Doing?
When students get to practice, they focus heavily on the basics:
- The "Easy" Stuff: Everyone practices on fake heads (phantom heads) to learn how to give a local anesthetic (numbing shot) and pull out a simple, loose tooth.
- The "Hard" Stuff: This is where the training gets thin. Very few schools have students practice on the really difficult extractions, like pulling out a wisdom tooth that is stuck deep in the jaw or breaking a tooth to remove the roots.
- The Analogy: It's like a swimming school where everyone practices floating and doggy-paddling perfectly, but almost no one gets to practice diving into deep water or swimming against a strong current, even though those are skills they might need later.
5. The Final Exam: The "Written Test" Problem
How do schools check if students are ready?
- The Current Method: The biggest part of the grade is still a written test. Students memorize facts and answer multiple-choice questions.
- The Gap: While some schools check if students can actually use the tools on a fake head, this isn't done everywhere.
- The Analogy: Imagine a driving test where you pass because you can recite the traffic laws perfectly on a piece of paper, but you've never actually been tested on whether you can parallel park without hitting the curb. The authors say the system is too focused on "book smarts" and not enough on "hands-on smarts."
The Bottom Line
The study concludes that China has a solid foundation for teaching tooth extraction, but it needs a tune-up.
- What's working: The core topics (numbing, simple extractions) are covered, and schools are using videos and models.
- What needs fixing: The course needs to stand on its own (not just be a chapter in a big book), students need more practice on the difficult extractions, schools need to use more high-tech interactive tools, and exams need to test actual skills, not just memory.
The goal is to make sure that when a new dentist graduates, they aren't just good at answering questions about pulling teeth, but are actually confident and safe at doing it.
