Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Teeth01:15

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...
Tooth Anatomy01:21

Tooth 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.
Veneer01:19

Veneer

Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Summary

A traumatic injury in a 5-month-old resulted in a lost mandibular incisor and a residual tooth. Long-term follow-up revealed another residual tooth, highlighting the importance of monitoring immature teeth after trauma.

Area of Science:

  • Pediatric Dentistry
  • Oral Surgery
  • Developmental Biology

Background:

  • Dental abnormalities are common in pediatric dentistry and require long-term monitoring.
  • Traumatic dental injuries in infants can lead to complex outcomes.
  • Residual teeth, often linked to Hertwig's epithelial sheath remnants, present diagnostic and management challenges.

Purpose of the Study:

  • To report a rare case of recurrent residual teeth following traumatic avulsion in an infant.
  • To emphasize the significance of long-term follow-up in managing dental trauma in young children.
  • To discuss the potential etiology of residual teeth related to immature root development.

Main Methods:

  • Case report of a 5-month-old male infant presenting with traumatic mandibular incisor loss.
  • Clinical examination and radiographic assessment to identify calcified tissue (residual tooth).
  • Surgical extraction of the residual tooth and subsequent one-year follow-up.

Main Results:

  • Initial trauma led to the loss of a mandibular incisor.
  • A residual tooth was detected and extracted.
  • A second residual tooth appeared in the same location one year later, indicating a recurring issue.
  • The residual teeth were associated with an immature root and Hertwig's epithelial sheath remnants.

Conclusions:

  • Residual teeth can occur even after traumatic avulsion in infants with immature roots.
  • Long-term dental follow-up is crucial for pediatric patients experiencing tooth loss due to trauma.
  • Clinicians should be aware of the potential for residual tooth formation and the importance of monitoring these cases.
