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.
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...
The Oral Microbiota01:27

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...
Oral Cavity01:11

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
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,...

Area of Science:

  • Dental research
  • Periodontology
  • Cariology

Background:

  • Root caries is a prevalent dental issue in periodontal patients, exacerbated by exposed root surfaces from periodontal disease and therapy.
  • Increased risk of root caries can jeopardize the long-term success of periodontally treated teeth.
  • This review focuses on root caries in periodontal patients and identifies unmet research needs.

Purpose of the Study:

  • To review the existing literature on root caries in periodontal patients.
  • To highlight areas requiring further investigation, particularly concerning risk factors and diagnostic criteria.
  • To emphasize the importance of prevention in managing root caries in this population.

Main Methods:

  • A comprehensive literature search of the Medline database was conducted.
  • The search focused on clinical features, diagnosis, pathogenesis, histopathology, and epidemiology of root caries.
  • Emphasis was placed on the relationship between root caries and periodontal disorders.

Main Results:

  • Despite extensive literature, consensus is lacking on diagnostic criteria, prevalence, and definitive risk factors for root caries.
  • Advancing age may be a contributing factor, but conclusive evidence is needed.
  • Awareness of the elevated root caries risk in periodontal patients remains insufficient.

Conclusions:

  • Further research is essential, especially concerning root caries in elderly periodontal patients.
  • Improved oral hygiene, preventive measures, diet, and regular dental visits are critical for preventing both periodontal disease and root caries.
  • Periodontal patients with root exposure must adhere to a strict root caries prevention protocol as part of their maintenance therapy.
