Reporting Quality of Prosthodontics-Related Systematic Reviews in SCI-E Indexed Journals: A PRISMA-Based Evaluation Short Title: Reporting Quality of Prosthodontics-Related Systematic Reviews
This study evaluated the reporting quality of 40 prosthodontics-related systematic reviews published in SCI-E journals between 2010 and 2019 using the PRISMA checklist, finding that while quality has significantly improved over time with publication year as the only significant predictor, important deficiencies in adherence to reporting standards remain.

Imagine the world of dental research as a massive library. Inside this library, there are thousands of books (studies) about how to fix teeth, specifically using crowns, bridges, and implants (prosthodontics). Sometimes, a single book isn't enough to tell the whole story. So, researchers write "Super Summaries" called Systematic Reviews. These books try to read all the other books on a specific topic, combine their findings, and give dentists one clear answer.
However, just like a recipe for a cake, a "Super Summary" is only as good as the instructions it follows. If the author forgets to list the ingredients or doesn't explain how they mixed the batter, you can't trust the cake.
This paper is like a quality control inspector who went into the library to check the "Super Summaries" written between 2010 and 2019. They used a specific checklist called PRISMA (think of it as a strict "Recipe Compliance Card") to see if these summaries were written correctly.
Here is what the inspectors found, broken down simply:
1. The Mission: Checking the Recipe Cards
The researchers looked at 160 different dental journals but only kept the ones that focused on prosthetic teeth. They filtered out anything that wasn't a "Super Summary" with a statistical mix (meta-analysis). In the end, they picked 40 specific articles to grade.
They gave each article a score out of 55 points. To pass, the article needed to clearly state:
- What question they were trying to answer.
- How they searched for other studies.
- How they checked if those studies were biased (like checking if a judge was bribed).
- How they combined the numbers.
2. The Scoreboard: Good, but Not Perfect
The scores ranged from 34 to 50.5.
- The Good News: The scores got better over time. Articles written after 2015 were like students who studied harder; they followed the "Recipe Compliance Card" much better than those written earlier.
- The Bad News: Even the best articles missed some steps. No one got a perfect 55.
- The Surprises: It didn't matter how many people wrote the paper (2 authors vs. 6 authors), where they were from (Europe vs. America), or which famous journal published it. The only thing that really mattered was when it was published.
3. Where Did They Drop the Ball?
The inspectors noticed two main places where the authors forgot to follow the rules:
- The "Bias" Check: Authors often forgot to explain how they checked if the original studies they were reviewing were flawed or biased. It's like a judge not explaining how they decided who won a race.
- The "Recipe" Registration: Many authors didn't register their plan before they started cooking. In research, this means writing down exactly what you plan to do before you start looking for data. Without this, it's hard to know if they changed the rules halfway through to get a better result.
4. The "Special Issue" Mystery
The paper also looked at "Special Issues" of journals. Imagine a magazine that usually covers all of dentistry, but for one month, they dedicate the whole issue to "Implants."
- The researchers found that most of these special issues were actually about implants, not general prosthetic teeth (like crowns on natural teeth).
- They noticed that many of these articles were first presented at big dental conferences before being published. It seems like the "Special Issue" editors often picked the best presentations from these conferences and turned them into journal articles.
- Funding: The paper noted that while the magazine's introduction often mentioned who paid for the research, the actual articles inside rarely did. This is like a movie showing a sponsor's logo in the trailer but not in the movie itself.
5. The Bottom Line
The paper concludes that time is the best teacher. As years went by, authors got better at following the rules. However, there are still gaps. To make these "Super Summaries" truly reliable for dentists to use on patients, authors need to be more transparent about:
- How they checked for bias.
- Registering their plans beforehand.
- Being clear about who paid for the research.
In short: The "Super Summaries" in dental journals are getting better, but they still need to follow the recipe more strictly to ensure the "cake" (the medical advice) is safe and reliable for everyone.
