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 grinding food.

The Oral Microbiota

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Area of Science:

Periodontology
Microbiology
Clinical Dentistry

Background:

Deep periodontal pockets (≥6 mm) present a therapeutic challenge in chronic periodontitis.
Conventional oral hygiene may be insufficient for managing subgingival bacterial load in these sites.

Purpose of the Study:

To evaluate the short-term clinical and microbiological effects of patient-applied subgingival root brushing.
To assess the efficacy of subgingival root brushing as an adjunctive therapy in untreated deep periodontal pockets.

Main Methods:

11 adults with untreated chronic periodontitis were enrolled.
Two contralateral deep periodontal sites (≥6 mm) per patient were selected.
One site received daily subgingival root brushing for 14 days; the other served as a control.

Main Results:

Subgingival root brushing significantly reduced plaque, bleeding on probing, and probing depth (mean 1.8 mm).
Total cultivable subgingival bacteria and proportions of key periodontal pathogens decreased dramatically.
Control sites showed no significant clinical or microbiological changes.

Conclusions:

Patient-applied subgingival root brushing effectively improves clinical and microbiological parameters in deep periodontal pockets.
This technique shows promise as an accessible, adjunctive treatment for periodontitis management.
Favorable outcomes were achieved without professional subgingival debridement.
