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 ...
Tooth development or odontogenesis is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth. 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 ...
Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion .) Tooth formation begins before birth, and the teeth's eventual morphology is ...

The neonatal line is darker and larger than the rest of the striae of retzius. The neonatal line is the demarcation between the enamel formation before birth and after birth i.e., prenatal and postnatal enamel respectively. [1] It is caused by the different physiologic changes at birth and is used to identify enamel formation before and after ...
Ellis–Van Creveld syndrome often is the result of founder effects in isolated human populations, such as the Amish and some small island inhabitants. Although relatively rare, this disorder does occur with higher incidence within founder-effect populations due to lack of genetic variability.
Development of the human body is the process of growth to maturity. The process begins with fertilization, where an egg released from the ovary of a female is penetrated by a sperm cell from a male. The resulting zygote develops through mitosis and cell differentiation, and the resulting embryo then implants in the uterus, where the embryo ...
Prenatal dental care is the care of the oral cavity during fetal development. The woman’s body is subject to hormonal changes leading to several physical changes in the oral cavity during pregnancy. Some of these changes may cause tooth decay, erosion and periodontal health changes. Proper dental care during pregnancy and recommended dental ...
