Neonatal teeth. Natal teeth are teeth that are present above the gumline (have already erupted) at birth, and neonatal teeth are teeth that emerge through the gingiva during the first month of life (the neonatal period). [1][2] The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the type of study; the ...
A 9-month-old infant with a visible right lower central incisor. Teething is the process by which an infant 's first teeth (the deciduous teeth, often called "baby teeth" or "milk teeth") appear by emerging through the gums, typically arriving in pairs. The mandibular central incisors are the first primary teeth to erupt, usually between 6 and ...
For human teeth to have a healthy oral environment, all parts of the tooth must develop during appropriate stages of fetal development. Primary (baby) teeth start to form between the sixth and eighth week of prenatal development, and permanent teeth begin to form in the twentieth week. [1] If teeth do not start to develop at or near these times ...
Early childhood caries (ECC), formerly known as nursing bottle caries, baby bottle tooth decay, night bottle mouth and night bottle caries, is a disease that affects teeth in children aged between birth and 71 months. [1][2] ECC is characterized by the presence of 1 or more decayed (non cavitated or cavitated lesions), missing (due to caries ...
Enamel hypoplasia. Enamel hypoplasia is a defect of the teeth in which the enamel is deficient in quantity, [1] caused by defective enamel matrix formation during enamel development, as a result of inherited and acquired systemic condition (s). It can be identified as missing tooth structure and may manifest as pits or grooves in the crown of ...
Deciduous teeth or primary teeth, also informally known as baby teeth, milk teeth, or temporary teeth, [1] are the first set of teeth in the growth and development of humans and other diphyodonts, which include most mammals but not elephants, kangaroos, or manatees, which are polyphyodonts. Deciduous teeth develop during the embryonic stage of ...
Pericoronitis. Pericoronitis associated with the lower right third molar (wisdom tooth). Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which ...
Hypodontia is defined as the developmental absence of one or more teeth excluding the third molars. It is one of the most common dental anomalies, and can have a negative impact on function, and also appearance. It rarely occurs in primary teeth (also known as deciduous, milk, first and baby teeth) and the most commonly affected are the adult ...
