Summary
This meta-analysis found electronic apex locators, conventional radiography, and digital radiography are equally effective for determining working length in primary teeth pulpectomy. These methods show similar reliability for this crucial endodontic procedure.
Area of Science:
- Dentistry
- Endodontics
- Pediatric Dentistry
Background:
- Accurate working length determination is critical for successful primary teeth pulpectomy.
- Various methods exist, but their comparative reliability needs evaluation.
Approach:
- A systematic review and meta-analysis following PRISMA guidelines.
- Searched PubMed, Scopus, Cochrane Library, and Web of Science for relevant studies.
- Included 14 studies for qualitative and 7 for quantitative analysis.
Key Points:
- Mean working length: Electronic apex locator (11.8mm), conventional radiography (12.42mm), digital radiography (12.3mm).
- No statistically significant differences were found between the methods in quantitative analysis.
- All evaluated methods demonstrated similar reliability for determining working length.
Conclusions:
- Electronic apex locators, conventional radiography, and digital radiography are comparable in determining working length for primary teeth pulpectomy.
- Clinicians can utilize any of these methods with similar confidence for accurate length determination.

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...
