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.

    Area of Science:

    • Pediatric Dentistry
    • Endodontics
    • Dental Anatomy

    Background:

    • Endodontics focuses on treating the root canal system in deciduous teeth to maintain dental arch function and eruption sequence.
    • Manual instrumentation, while common, has limitations in cleaning efficiency and risks procedural errors like perforations and instrument fractures.
    • Nickel-titanium instruments are costly and can lead to excessive dentin removal, compromising tooth stability.

    Purpose of the Study:

    • To analyze the complex anatomy of the endodontic system in deciduous teeth.
    • To provide a detailed understanding of root canal morphology in primary teeth for improved clinical practice.

    Main Methods:

    • Computed microtomography (μCT) was employed to examine extracted deciduous teeth.
    • Detailed analysis of the internal morphology of the root canal system was performed.

    Main Results:

    • The study provided a comprehensive analysis of deciduous tooth root canal anatomy.
    • Specific anatomical features and variations within the endodontic system were identified.

    Conclusions:

    • Accurate knowledge of deciduous endodontic anatomy is essential for successful treatment outcomes.
    • Advanced imaging techniques like μCT offer significant advantages in studying dental hard tissues and root canal systems.
