| immediate hypersensitivity reaction | An immune response mediated by antibody, usually IgE, which occurs within minutes after a second encounter with an antigen, resulting in the release of histamine and subsequent swelling and vasodilation. (05 Mar 2000) |

| delayed dentition | Delayed eruption of the teeth. (05 Mar 2000) |
| delayed eruption | A dental eruption pattern which is chronologically late in comparison with the average pattern of dental eruption; eruption of the first tooth occurs at a later age than the average, and the intervals of time between subsequent dental eruption's are longer than the average. Drug eruption, any eruption caused by the ingestion, injection, or inhalation of a drug, most often the result of allergic sensitization; reactions to drugs applied to the cutaneous surface are not generally designated as drug eruption, but as contact-type dermatitis. Synonym: dermatitis medicamentosa, dermatosis medicamentosa, drug rash, medicinal eruption. (05 Mar 2000) |
