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...
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,...
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.
Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Area of Science:

  • Dentistry
  • Pediatric Dentistry
  • Oral Medicine

Background:

  • Natal teeth are present at birth; neonatal teeth erupt within the first month of life.
  • The incidence of natal/neonatal teeth ranges from 1 in 2000 to 1 in 3500 live births.
  • Commonly affected teeth are mandibular central incisors, followed by maxillary incisors and mandibular canines.

Purpose of the Study:

  • To report a rare case of bilateral neonatal teeth in the maxillary molar region.
  • To discuss the clinical significance and management of such rare dental anomalies.

Main Methods:

  • Clinical case presentation.
  • Review of relevant literature on natal and neonatal teeth.

Main Results:

  • The case involves a rare occurrence of bilateral neonatal teeth in the maxillary molar region.
  • This presentation is significantly less common than natal or neonatal teeth in the incisor or canine regions.

Conclusions:

  • Bilateral neonatal maxillary molar teeth are an exceptionally rare dental anomaly.
  • Early diagnosis and appropriate management are crucial for potential complications like feeding difficulties or aspiration risks.
