Teeth

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...

Summary

The Eigenfactor Score™ better reflects journal prestige in dentistry than the Impact Factor. Differences in rankings are influenced by article types, self-citations, and citing time, highlighting the need for specialized bibliometric measures.

Area of Science:

Bibliometrics
Medical Informatics
Dental Research

Background:

Journal ranking metrics like Impact Factor (IF) and Eigenfactor Score (ES) are crucial for evaluating scientific publications.
Discrepancies between IF and ES necessitate investigation, particularly within specialized medical fields.

Purpose of the Study:

To compare Eigenfactor Score (ES) and Impact Factor (IF) journal rankings in dentistry over five years.
To identify factors influencing the differences between ES and IF rankings.

Main Methods:

Comparative analysis of journal rankings using data from Thomson Reuters and Eigenfactor Score™.
Inclusion of 46 dental journals.
Multivariate regression analysis to identify influencing variables.

Main Results:

Significant variations in journal ranks were observed between ES and IF metrics.
Bland-Altman analysis indicated poor agreement between the two metrics.
Number of original research articles, review articles, self-citations, and citing time significantly influenced rank differences.

Conclusions:

Eigenfactor Score™ may offer a more accurate reflection of journal prestige in dentistry compared to Impact Factor.
Bibliometric indicators in medicine should consider specialized fields, not just the overall medical landscape.
Development of distinct measures is needed to accurately assess the scientific impact of specialized medical publications.
