Disorders of tooth development and eruption (K00)

Clinical Information for Disorders of tooth development and eruption (K00)

Anodontia - Congenital absence of the teeth; it may involve all (total anodontia) or only some of the teeth (partial anodontia, hypodontia), and both the deciduous and the permanent dentition, or only teeth of the permanent dentition. (Dorland, 27th ed)

Hypohidrosis - Abnormally diminished or absent perspiration. Both generalized and segmented (reduced or absent sweating in circumscribed locations) forms of the disease are usually associated with other underlying conditions.

Dental Pulp Calcification - CALCINOSIS of the DENTAL PULP or ROOT CANAL.

Dentin Dysplasia - An apparently hereditary disorder of dentin formation, marked by a normal appearance of coronal dentin associated with pulpal obliteration, faulty root formation, and a tendency for peripheral lesions without obvious cause. (From Dorland, 27th ed)

Dentinogenesis Imperfecta - An autosomal dominant disorder of tooth development characterized by opalescent dentin resulting in discoloration of the teeth. The dentin develops poorly with low mineral content while the pulp canal is obliterated.

Nephrocalcinosis - A condition characterized by calcification of the renal tissue itself. It is usually seen in distal RENAL TUBULAR ACIDOSIS with calcium deposition in the DISTAL KIDNEY TUBULES and the surrounding interstitium. Nephrocalcinosis causes RENAL INSUFFICIENCY.

Osteopetrosis - Excessive formation of dense trabecular bone leading to pathological fractures; OSTEITIS; SPLENOMEGALY with infarct; ANEMIA; and extramedullary hemopoiesis (HEMATOPOIESIS, EXTRAMEDULLARY).

Osteosclerosis - An abnormal hardening or increased density of bone tissue.

Amelogenesis Imperfecta - A clinically and genetically heterogeneous group of hereditary conditions characterized by malformed DENTAL ENAMEL, usually involving DENTAL ENAMEL HYPOPLASIA and/or TOOTH HYPOMINERALIZATION.

Steatocystoma Multiplex - A disorder characterized by multiple, wide spread cutaneous cysts that often become inflamed and rupture. It is caused by the same mutations in the gene coding for KRT-17 that are causative mutations for Pachyonychia congenita, Type 2. Natal teeth involvement is sometimes associated with steatocystoma multiplex.

Natal Teeth - Predeciduous teeth present at birth. They may be well formed and normal or may represent hornified epithelial structures without roots. They are found on the gingivae over the crest of the ridge and arise from accessory buds of the dental lamina ahead of the deciduous buds or from buds of the accessory dental lamina. (From Jablonski, Dictionary of Dentistry, 1992)

Tooth Loss - The failure to retain teeth as a result of disease or injury.

Toothache - Pain in the adjacent areas of the teeth.

Dens in Dente - Anomaly of the tooth, found chiefly in upper lateral incisors. It is characterized by invagination of the enamel at the incisal edge.

Instructional Notations

Type 2 Excludes Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
