Summary
Pulpectomy in primary teeth can lead to overretention of deciduous teeth, potentially causing ectopic eruption of permanent incisors. Regular monitoring is crucial to manage these cases and prevent malocclusion.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Orthodontics
Background:
- Pulpectomy is a standard procedure for preserving primary teeth and periapical health.
- Overretention of primary teeth after pulpectomy can complicate permanent tooth eruption.
Purpose of the Study:
- To describe and analyze the ectopic eruption of permanent incisors following pulpectomy of their primary predecessors.
- To evaluate the outcomes of managing overretained primary incisors after pulpectomy.
Main Methods:
- A retrospective study of 135 primary teeth treated with pulpectomy due to caries.
- Clinical and radiographic follow-up for at least 3.5 years for 10 overretained primary maxillary incisors.
- Extraction of overretained primary teeth guided by eruption chronology and contralateral tooth comparison.
Main Results:
- Ten primary maxillary incisors showed overretention after pulpectomy.
- Seven of the corresponding permanent incisors exhibited ectopic eruption.
- Spontaneous correction of permanent tooth position occurred in five of the seven ectopically erupted teeth.
Conclusions:
- Periodic clinical and radiographic assessments are vital after primary tooth pulpectomy.
- Monitoring is necessary to detect radicular resorption and ZOE (Zinc Oxide Eugenol) paste resorption.
- Early intervention for overretained primary teeth can prevent malocclusion and ectopic eruption.

01:15Teeth
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...

01:21Tooth Anatomy
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 grinding food.
