|October 20, 2022
Summary
Orthodontic research quality is improving unevenly, with many studies lacking robust statistical analysis and reporting. Key areas for improvement include randomized controlled trials and advanced statistical methods for better understanding treatment effects.
Area of Science:
- Orthodontics
- Dental Research
- Scientific Literature Analysis
Background:
- The orthodontic literature is a primary source of evidence for clinical practice.
- Understanding the characteristics and quality of published research is crucial for evidence-based dentistry.
Purpose of the Study:
- To comprehensively characterize the features of orthodontic research articles published in 2020.
- To identify strengths and weaknesses in the methodology and reporting of current orthodontic literature.
Main Methods:
- A systematic review of 350 research articles from three leading orthodontic journals in 2020.
- Articles were categorized based on 48 features, including study design, analytical tools, and reporting characteristics.
Main Results:
- The typical study was a cohort study with multiple outcomes at one site.
- Analytical soundness was inconsistent; many studies lacked data on power, normality, or measurement consistency.
- Few studies addressed covariables or adjusted for multiple outcome tests.
Conclusions:
- The quality of orthodontic research has advanced unevenly, with significant gaps in methodology.
- Areas needing improvement include adherence to standards for randomized controlled trials and the application of advanced statistical techniques like regression analysis.

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...

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

01:31Osteoclasts in Bone Remodeling
3.1K
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...

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...
