Summary
Root canal overfilling in primary teeth was studied using various material placement techniques. The plugger technique for zinc oxide-eugenol and the handheld lentulo spiral for calcium hydroxide showed the lowest overfilling rates in clinical studies.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Dental Materials Science
Background:
- Root canal overfilling in primary teeth is a clinical concern.
- Material placement techniques influence overfilling rates.
- Understanding these rates is crucial for effective primary tooth pulpectomy.
Purpose of the Study:
- To systematically investigate root canal overfilling rates associated with different material placement techniques in primary teeth.
- To compare the efficacy of various techniques in minimizing overfilling during pulpectomy procedures.
Main Methods:
- A systematic literature search was conducted on PubMed/MEDLINE and Scopus for relevant peer-reviewed articles published until February 2018.
- Two independent reviewers screened studies and extracted data on primary tooth pulpectomy overfilling.
- Random-effects meta-analysis was employed to estimate weighted pooled overfilling rates from clinical studies.
Main Results:
- Twenty clinical and four in vitro studies met the eligibility criteria.
- For zinc oxide-eugenol (ZOE), pooled overfilling rates were 23.3% (handpiece lentulo spiral), 22.7% (handheld lentulo spiral), and 17% (plugger).
- For calcium hydroxide-based materials, rates were 16.7% (handpiece lentulo spiral), 14.7% (handheld lentulo spiral), 19.6% (syringe), and 25.7% (plugger).
Conclusions:
- The plugger technique demonstrated the lowest overfilling rate for zinc oxide-eugenol in clinical settings.
- The handheld lentulo spiral technique showed the lowest overfilling rate for calcium hydroxide-based materials in clinical settings.

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...
