Summary
Statistical analysis in orthodontic research has increased significantly since 1975. While descriptive statistics use rose, inferential statistics use slightly declined between 2003 and 2008 in the American Journal of Orthodontics and Dentofacial Orthopedics.
Area of Science:
- Orthodontic research methodology
- Biostatistics in dental journals
Background:
- The American Journal of Orthodontics and Dentofacial Orthopedics (AJODO) is a leading publication in its field.
- Understanding statistical trends in published research is crucial for evaluating scientific rigor.
Purpose of the Study:
- To analyze the trends in statistical methods used in AJODO articles.
- To compare statistical usage in 2008 with data from 1975, 1985, and 2003.
Main Methods:
- Original articles published in AJODO in 2008 were reviewed.
- Statistical procedures were categorized as descriptive or inferential.
- Data were compared across multiple decades.
Main Results:
- The proportion of AJODO articles employing statistics increased from 43.1% in 1975 to 92.9% in 2008.
- Between 2003 and 2008, articles using inferential statistics decreased from 92.9% to 84.4%.
- Descriptive statistics usage in articles increased from 7.1% to 15.6% between 2003 and 2008.
Conclusions:
- The overall use of statistics in AJODO remained high between 2003 and 2008.
- A notable shift occurred, with a decrease in inferential statistics and an increase in descriptive statistics usage in recent years.

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...
02:46Chi-square Analysis
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
