Summary
Dental age (DA) may correlate with malocclusion types. Skeletal Class III and vertical growth patterns are linked to advanced DA, while cross-bite suggests delayed DA, indicating its potential orthodontic diagnostic use.
Area of Science:
- Orthodontics
- Dental Development
- Radiodontics
Background:
- Dental age (DA) assessment is crucial for diagnosing developmental anomalies.
- Malocclusions, including skeletal and dental types, are implicated in altered dental development.
- Existing literature suggests a link between malocclusion and advanced or delayed DA.
Purpose of the Study:
- To systematically review the association between dental age and various malocclusion types.
- To synthesize evidence on how sagittal, vertical, and transversal discrepancies relate to DA.
Main Methods:
- Comprehensive literature search across major databases (PubMed, Scopus, Web of Science, etc.) and gray literature.
- Inclusion of observational studies assessing DA and malocclusion types (sagittal, vertical, transversal).
- Quality assessment using Newcastle-Ottawa Scale (NOS) and evidence certainty evaluation via GRADE approach.
Main Results:
- Twenty studies were included, with most showing moderate quality.
- Sagittal discrepancies were most frequently studied, followed by vertical and transversal.
- Advanced DA observed in vertical growth patterns and males with skeletal Class III; delayed DA in unilateral posterior cross-bite.
- Certainty of evidence for all outcomes was rated as very low.
Conclusions:
- Dental age may be associated with specific malocclusion types.
- DA shows potential as an initial diagnostic tool in orthodontics.
- Further high-quality research is needed to clarify the DA-malocclusion relationship.

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...

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...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
