Summary
Natal and neonatal teeth, often mandibular central incisors, present unique clinical challenges. Early identification and appropriate management, including extraction for mobility or retention when stable, are crucial for infant oral health.
Area of Science:
- Pediatric Dentistry
- Neonatal Care
- Oral Health
Background:
- Natal and neonatal teeth are present at birth or within the first month of life, respectively.
- Their occurrence, clinical presentation, and management require specific knowledge for healthcare providers.
Purpose of the Study:
- To investigate the clinical characteristics and management strategies for natal and neonatal teeth.
- To identify risk factors associated with their development.
Main Methods:
- A study involving 52 children with natal or neonatal teeth.
- Included interviews on parental and pregnancy history and clinical examinations assessing tooth appearance, mobility, and soft tissue conditions.
- Follow-up until permanent incisor eruption.
Main Results:
- Natal teeth occurred in 73.8% and neonatal in 26.92% of cases; all were mandibular central incisors.
- Enamel hypoplasia was noted in 27.9% of teeth, and 49.1% of natal teeth were extracted due to excessive mobility.
- Riga-Fede ulceration observed in 5.7%; extended gestational period linked to increased natal tooth risk (OR=1.9975).
Conclusions:
- Natal and neonatal teeth require careful clinical assessment and management.
- Extraction is indicated for excessive mobility, while retention is recommended otherwise.
- Awareness among dentists and pediatricians is vital for comprehensive newborn oral examinations.

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...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
