    Insights

    Natal teeth affect approximately 1 in 289 newborns, while neonatal teeth occur in about 1 in 2,212. Healthcare providers should be vigilant for these conditions, as early detection of natal and neonatal teeth is crucial for prompt intervention.

    Area of Science:

    • Pediatric Dentistry
    • Neonatal Care
    • Oral Health Epidemiology

    Background:

    • Identifying natal and neonatal teeth in newborns is critical due to potential immediate care needs.
    • This systematic review and meta-analysis aimed to establish the global prevalence of natal and neonatal teeth.

    Approach:

    • A comprehensive search of six electronic databases and gray literature was conducted on February 23, 2023.
    • Observational studies reporting prevalence were included; studies lacking prevalence data or equating natal and neonatal teeth were excluded.
    • Methodological quality was assessed using the Joanna Briggs Institute checklist, and prevalence was estimated using a β-binomial proportion meta-analysis.

    Key Points:

    • The worldwide prevalence of natal teeth was estimated at 34.55 per 10,000 (95% CI, 20.12 to 59.26).
    • The worldwide prevalence of neonatal teeth was estimated at 4.52 per 10,000 (95% CI, 2.59 to 17.91).
    • Prevalence varied significantly by continent, with natal teeth ranging from 11.26 (Asia) to 75.32 (North America) per 10,000, and neonatal teeth from 3.52 (Europe) to 6.01 (South America) per 10,000.

    Conclusions:

    • Natal teeth affect approximately 1 in 289 newborns, and neonatal teeth affect about 1 in 2,212.
    • Despite the low prevalence, healthcare professionals must remain alert for these conditions, which often necessitate immediate dental care.

    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...

    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...

    Prevalence and Incidence01:08

    Prevalence and Incidence

    In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
    Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

    Assessment of the Mouth01:26

    Assessment 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.

    Bias in Epidemiological Studies01:29

    Bias in Epidemiological Studies

    Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

    Teratogenicity01:07

    Teratogenicity

    The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
