The sensitivity of the developing tooth germ to systemic disturbances
Early Human Development
|April 1, 1984
Summary
Tooth development lines in enamel and dentine correlate with infant or maternal illness. These dental lines indicate environmental disturbances but are not specific to any single cause.
Area of Science:
- Pediatric Dentistry
- Developmental Biology
- Forensic Anthropology
Background:
- Deciduous teeth form during fetal development and early infancy.
- Histological analysis of tooth structures can reveal developmental disturbances.
- Systemic health events can impact tooth mineralization and growth patterns.
Purpose of the Study:
- To investigate the relationship between histological lines in deciduous tooth germs and systemic health.
- To determine if dental enamel or dentine is a more sensitive indicator of environmental disturbances.
- To assess the specificity of dental lines as markers for health events.
Main Methods:
- Deciduous tooth germs were collected from 76 stillborn infants and infants who died within the first year of life.
- Histological examination was performed to identify lines in enamel and dentine.
- Chronological correlation was sought between identified lines and recorded maternal or infant systemic illnesses.
Main Results:
- Histological lines were identified in the enamel and dentine of deciduous teeth.
- A chronological association between these lines and systemic illness was observed in 50% of the cases studied.
- Enamel exhibited greater sensitivity to environmental factors compared to dentine, though the causes of disturbance were non-specific.
Conclusions:
- Deciduous teeth serve as a sensitive indicator of environmental disturbances during development.
- The presence of lines in enamel and dentine suggests a link to systemic health events in the child or mother.
- While indicative of disturbance, dental lines are non-specific markers and do not pinpoint exact etiological agents.

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

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.

01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:27The 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...
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,...
