Birth Weight, Pregnancy Complications Linked to Enamel Defects



Enamel defects may be impacted during the events that transpire during pregnancy, based on a new study.

A cross sectional representative study focused on assessing the relationship between birth weight and the severity of defects development of enamel in the primary dentition. The study was presented at the 93rd General Session and Exhibition of the International Association for Dental Research. The IADR General Session was held in conjunction with the 44th Annual Meeting of the American Association for Dental Research and the 39th Annual Meeting of the Canadian Association for Dental Research.

More than 1,300 five-year-old children who were enrolled in kindergarten in Brazil took part in the study. The children were examined for defects development of enamel. The mothers were then asked questions regarding complications during pregnancy. The response variable depended on the severity of the defects involving the enamel. All the other factors, including the child’s gender, age of his or her mother during pregnancy, etc. were also considered.

The results showed that defects development of enamel appeared 22.7 percent of the time with greater severity and 77.3 percent with minor severity. The study revealed that the condition impacted more children with a low birth weight. That’s why the researchers concluded that low birth weight and hypertension are risk factors for defects development of enamel.

This research was supported by the following agencies in Brazil: Fundacao de Amparo a Pesquisa do Estado de Minas Gerais, Fundacao Capes Ministério da Educacao and Ministerio da Ciencia, Tecnologia e Inovacao.
