Summary
Understanding tooth enamel formation is key for dentists. This review details the biological processes, defects like amelogenesis imperfecta (AI), and biomimetic strategies for better dental care.
Area of Science:
- Biomineralization
- Dental Tissues
- Developmental Biology
Background:
- Tooth enamel, the body's hardest tissue, protects against challenges but is prone to defects.
- Understanding enamel formation is crucial for oral health professionals to advance preventive and therapeutic strategies.
- This review synthesizes knowledge on enamel formation, its disruptions, and biomimetic approaches.
Purpose of the Study:
- To review the cellular, molecular, and structural determinants of enamel formation.
- To discuss clinically relevant enamel defects and emerging biomimetic strategies.
- To provide oral health professionals with a framework for managing enamel conditions.
Main Methods:
- Scoping review following PRISMA-ScR guidelines.
- Systematic literature search of Embase and Medline databases.
- Thematic synthesis of 92 selected publications.
Main Results:
- Enamel formation involves complex stages with ameloblast activity and matrix protein secretion.
- Key mechanisms include proteolytic processing and controlled ion transport for hydroxyapatite crystal growth.
- Identified causes of enamel defects (fluorosis, hypomineralization, AI) and highlighted biomimetic strategies.
Conclusions:
- Enamel formation is a highly coordinated biomineralization process regulated at multiple levels.
- Disruptions in these processes lead to significant enamel pathologies.
- Integrating mechanistic insights with biomimetic technologies offers promising dental care advancements.

01:15Teeth
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...

01:21Tooth 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.

01:28Development 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,...
01:26Assessment of the Mouth
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.
