Summary
Third molar mineralization correlates with midpalate suture maturity in dental development. However, this dental development stage cannot precisely determine midpalate suture maturation for treatment timing.
Area of Science:
- Dentistry
- Orthodontics
- Radiology
Background:
- Midpalatal suture ossification timing varies, making chronological age an unreliable indicator for orthodontic treatment.
- Dental development, specifically tooth mineralization, may offer a more precise method for assessing skeletal growth and maturation.
Purpose of the Study:
- To investigate the correlation between third molar mineralization stages and midpalatal suture maturation using cone-beam computed tomography (CBCT).
Main Methods:
- Analyzed 97 CBCT scans of patients aged 8-37 years with normal development.
- Assessed midpalatal suture ossification using the Angelieri et al. protocol.
- Measured third molar mineralization using the Demirjian index.
Main Results:
- A significant positive correlation (R=0.814, P<0.01) was observed between advanced third molar mineralization and increased midpalatal suture maturity.
- Third molar development also showed a strong association with chronological age (R=0.883, P<0.01).
Conclusions:
- While third molar mineralization correlates with midpalatal suture maturation, it is not a precise predictor for determining treatment timing.
- Dental development indicators like third molar mineralization offer insights but require careful interpretation alongside other diagnostic tools.

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...

01:22Sutures of the Skull
6.9K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
