Retrospective Database Study: Survival of Cast Restorations - Restorations Made of Precious Metal vs. Non-precious Metal
This study is like a detective story, looking back at old dental records. Researchers are examining how long certain types of dental restorations, like crowns and partial crowns made from either precious (expensive) or non-precious metals, lasted. They're reviewing information from patients treated between 1997 and 2022. The main goal is to compare how well these different metal restorations survive and what factors, such as the patient's age or the tooth's condition, might affect their lifespan. It's important to know that no new treatment is being given as part of this study; it's all about reviewing existing information.
At a glance
What is this study about?
Imagine you have a filling or a crown on one of your teeth. How long do you expect it to last? This study aims to answer that question by carefully looking at past dental records. Specifically, it's comparing two types of metal used for these "single-tooth cast restorations" – that's a fancy way of saying a crown or a partial crown for one tooth. They're looking at those made from precious metals (like gold) versus non-precious metals (like more common, less expensive ones).
The researchers are going over records from patients who had these dental procedures between 1997 and 2022. They want to see how long these restorations stayed in good shape before needing repair or replacement. They're also interested in whether things like the patient's age, the specific tooth involved, or the way the treatment was done had an impact on how long the restoration lasted.
This study is important because understanding what makes dental work last longer can help dentists make better choices for their patients in the future. It’s a way of learning from the past to improve future dental care. There’s no new treatment involved, and patients won't be asked to do anything or receive any medication as part of this research.
Key takeaways
- This study reviews old dental records, not new patients.
- It compares how long crowns and fillings made of different metals last.
- Data covered is from 1997 to 2022.
- The goal is to improve future dental care by understanding what makes treatments last.
- No patient interaction or new treatments are involved.
Who may be eligible?
This study is looking at information from people who have already had dental work in the past. You won't be asked to participate directly or change anything about your current dental care.
The researchers are specifically interested in reviewing the dental records of patients who, between 1997 and 2022, received single-tooth crowns or partial crowns made from either precious or non-precious metals. This dental work must have been carried out at a specific department of dentistry.
There are no particular reasons why someone's records would be excluded if they meet these inclusion criteria. The study welcomes records from people of all ages and genders.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Did you have a single-tooth crown or a partial crown (filling) placed between 1997 and 2022?
- Was your crown/filling made of either precious (e.g., gold) or non-precious metal?
- Was this dental work done at the Department of Preventive Dentistry, Periodontology and Cariology?
- Are you eligible for statutory health insurance (meaning your records might be included)?
What does participation involve?
Please note, this study does not involve any direct patient participation. You will not be asked to attend any appointments, undergo any assessments, take any medication, or have any follow-up visits. Instead, researchers will be looking back at existing anonymised dental records from patients who received certain dental treatments between 1997 and 2022. Your personal information will be kept private and not linked to the study findings.
