Tooth Anatomy

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...

Summary

This summary is machine-generated.

Infected dentine from root surface caries or cavitated coronal lesions does not require removal to arrest progression. Mechanical plaque control, fluoride, and sealing infected dentine are effective for caries management.

Area of Science:

Dentistry
Cariology
Restorative Dentistry

Background:

Dentine infection occurs with root surface caries and progressing enamel lesions.
The primary driver of caries lesion formation and progression is the overlying biofilm.
This highlights the importance of biofilm control in managing dentine infections.

Purpose of the Study:

To evaluate the necessity of removing infected dentine for caries arrest.
To determine alternative methods for managing root surface and coronal caries.
To assess the risks associated with aggressive excavation of deep carious lesions.

Main Methods:

Review of current understanding of caries progression and dentine infection.
Analysis of the efficacy of mechanical plaque control and fluoride in arresting root caries.
Evaluation of sealing strategies for infected dentine, including Hall crowns and partial caries removal.

Main Results:

Root surface caries can be arrested effectively with mechanical plaque control and fluoride, without the need for restorations.
Infected dentine in cavitated coronal lesions does not necessitate complete removal for arrest if the lesion is accessible for cleaning.
Sealing infected dentine, through methods like Hall crowns or well-sealed fillings after partial excavation, effectively arrests lesions.

Conclusions:

Restorations are not essential for arresting root surface caries; biofilm management is key.
Complete excavation of infected dentine in deep, asymptomatic lesions is unnecessary and increases the risk of pulp exposure and subsequent root canal treatment.
Conservative management, focusing on biofilm control and sealing, is recommended for deep carious lesions in vital teeth.
