Summary
Orthodontic treatment can increase root resorption, with heavy forces potentially being harmful. Light forces are recommended, especially during incisor intrusion, to minimize risks.
Area of Science:
- Dentistry
- Orthodontics
- Periodontology
Background:
- Root resorption is a potential outcome of orthodontic tooth movement.
- Minimizing risks and severity of root resorption is crucial for clinical decisions.
Purpose of the Study:
- To systematically review root resorption as an outcome in orthodontic tooth movement.
- To provide evidence for clinical decisions to minimize risks and severity of root resorption.
Main Methods:
- Systematic review of randomized clinical trials with fixed appliances.
- Searches included electronic and non-electronic databases, with no language restrictions.
- Data extraction by two independent reviewers.
Main Results:
- 13 studies were included from 921 unique citations.
- Comprehensive orthodontic treatment may increase root resorption incidence and severity; heavy forces may be harmful.
- Treatment pauses (2-3 months) might decrease total root resorption; other factors like archwire sequencing, bracket prescription, self-ligation, previous trauma, and tooth morphology appear unaffected.
Conclusions:
- Clinical management of root resorption remains inconclusive.
- Evidence supports using light forces, particularly for incisor intrusion, to mitigate root resorption.

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...

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
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.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
