Pulp calcification (PC) affects over 20% of children experiencing dental trauma. Recurrent trauma significantly increases the risk of developing PC in primary teeth.
Area of Science:
- Pediatric Dentistry
- Dental Traumatology
- Oral Radiology
Background:
- Dental trauma is a common occurrence in primary teeth.
- Pulp calcification (PC) is a known sequela of dental trauma, potentially affecting tooth vitality and development.
Purpose of the Study:
- To determine the prevalence of pulp calcification (PC) in children who have experienced trauma to their primary teeth.
- To identify risk factors associated with the development of PC following dental trauma.
Main Methods:
- Retrospective analysis of clinical and radiographic records of 1675 traumatized primary teeth from 946 patients.
- Statistical evaluation using chi-square and univariate logistic regression to assess prevalence and risk factors.
Main Results:
- Pulp calcification (PC) was observed in 20.8% of patients and 14.9% of teeth.
- PC typically appeared within 12 months post-trauma.
- Recurrent trauma (29.6%) showed a significantly higher prevalence of PC compared to single trauma (16.4%), with recurrent injuries increasing the odds by 2.14 times.
- Trauma to supportive tissues (67.4%) was significantly more associated with PC than trauma to dental tissues.
Conclusions:
- Pulp calcification (PC) is a frequent sequela of trauma in primary dentition.
- Recurrent traumatic injuries represent a significant risk factor for developing PC in primary teeth.

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.

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...
