Summary
Removable dental prostheses (RPD) did not significantly reduce tooth loss compared to no prosthesis (SDA) in adults over 35 years old. This 3-year interim analysis found similar tooth loss rates between the two groups.
Area of Science:
- Dental science
- Prosthodontics
- Clinical dentistry
Background:
- A multi-center randomized controlled trial evaluated tooth loss in patients over 35 years old with no molars.
- Patients were allocated to receive either a removable dental prosthesis (RPD) or no prosthesis (SDA).
Discussion:
- This interim analysis at 3 years reports on tooth loss rates and Kaplan-Meier survival estimates.
- Tooth loss occurred in 16% of the RPD group and 13% of the SDA group.
- Kaplan-Meier tooth survival rates at 38 months were 0.83 for RPD and 0.86 for SDA.
Key Insights:
- No significant difference in tooth loss was observed between the RPD and SDA groups at the 3-year mark.
- The study provides interim data on the efficacy of RPDs in preventing tooth loss.
Outlook:
- Further follow-up is needed to determine the long-term effects of RPDs on tooth retention.
- This research contributes to understanding prosthetic interventions for edentulous patients.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
