Congenital factors and Malocclusion

Innate factors are mainly environmental factors before birth, during which the mother the fetus, embryo, or both, subject to certain environmental factors which lead to fetal abnormalities dental organ.

It should be noted, though not necessarily innate genetic factors, but they are inborn genetic factors, including the following aspects.

(1) maternal factors during pregnancy, the mother of malnutrition, metabolic disorders or infectious diseases, will result in dental abnormalities.

If the mother suffering from rubella in early pregnancy, the possibility of fetal deformity significantly increased; if syphilis, can be passed to the fetus through the placenta to Dental Reviews jaw abnormalities, can be seen in future chess-like teeth and mulberry Hawkinson's front teeth;

If the mother during pregnancy endocrine disorders, also affect normal fetal development. Research has shown: the increase of adrenal cortex hormones, can cause cleft palate to happen.

In addition, early pregnancy, the mother, such as by excessive radiation exposure, may also cause fetal abnormalities caused by malocclusion.

(2) factors in fetal fetus early in development, has its own endocrine glands involved in their metabolism. If the fetus's own endocrine disorders, congenital abnormalities can cause the emergence of malocclusion.

In addition, fetal abnormalities in utero environment, such as malposition, abnormal amniotic fluid pressure, cord entanglement, etc., can be orofacial anomalies of external forces, there malocclusion. ,

(3) pregnancy and birth trauma, trauma during pregnancy or childbirth when the mother suffered trauma caused by birth trauma, may cause fetal abnormalities caused by maxillofacial deformities.

Acquired factors: that the environment in which patients after birth, and other factors.

(1) acute or chronic diseases: some acute infectious diseases such as measles, scarlet fever, chicken pox, smallpox, due to abnormal increase in body temperature, can affect the normal process of tooth mineralization, resulting in enamel hypoplasia, and even affect the jaw normal development.

Tuberculosis and other chronic indigestion and long-term wasting disease, caused by the body's nutritional status, also affect the normal development of jaw and tooth eruption, resulting in malocclusion.
