[10] [11] [12] The National Institutes of Health include a dental exam in the diagnostic protocol of celiac disease. [10] Enamel hypoplasia is believed to result from the dysfunction of ameloblasts—enamel-producing cells—either for a short period of time or throughout their lifespan. Enamel hypoplasia has a wide variety of known causes.
Amelogenesis imperfecta (AI) is a congenital disorder which presents with a rare abnormal formation of the enamel [1] or external layer of the crown of teeth, unrelated to any systemic or generalized conditions. [2] Enamel is composed mostly of mineral, that is formed and regulated by the proteins in it.

This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes Q00-Q99 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category.
When a patient has multiple abnormalities (multiple anomaly, multiple deformity), they have a congenital abnormality that cannot be primarily identified with a single system of the body or single disease process. [1]
They can be due to deformity or malformation. [1] An example is Klippel–Feil syndrome. [citation needed] Although present at birth, some only become obvious ...
Craniofacial abnormalities are congenital musculoskeletal disorders which primarily affect the cranium and facial bones. [1]They are associated with the development of the pharyngeal arches. [2]
Creep or plastic deformation happens when subjected to intra-oral stresses such as chewing or grinding. Creep causes the amalgam to flow and protrudes from the margin of the cavity forming unsupported edges. "Ditch" is formed around the margins of the amalgam restoration after fracture due to amalgam creep at the occlusal margins.
