1) Syphilitic
Syphilitic ulcers, specifically the chancre associated with primary syphilis, are classically described as having "punched out" margins and a clean base. This distinct appearance helps in clinical differentiation from other types of ulcers.

OrthodonticsIndicators for Class II activator include mandibular retrusion, horizontal/anterior mandibular growth, and upright lower anteriors. Crowding in lower anteriors is not a specific indicator for its use.

General MedicineSerum glutamic oxaloacetic transaminase (SGOT/AST) is increased in myocardial infarction. AST is released from damaged myocardial cells and peaks 24-48 hours after MI. While not specific to heart, it was historically used for MI diagnosis before troponins became available.

1. Anodontia: This is the complete absence of teeth. It is a rare condition
where an individual fails to develop any teeth.
2. Oligodontia: This term is used when an individual has fewer teeth than the
typical dental formula, which is six incisors, two canines, two premolars, and
six molars in the permanent dentition (excluding the third molars or wisdom
teeth). The term "hypodontia" is often used synonymously with oligodontia, but
hypodontia can also refer to a broader range of conditions characterized by the
congenital absence of one or more teeth, whereas oligodontia is more
specifically the absence of six or more teeth.
3. Microdontia: This condition involves teeth that are smaller than normal. It
can affect either the primary or permanent dentition and may involve one tooth
or multiple teeth.
4. Dens in dente: This is a rare developmental anomaly where a tooth forms
within the dental crown of another tooth, typically in the form of a small
tooth-like structure. It is not a condition of tooth number but rather an
abnormality of tooth structure.

Conservative DentistryFor porcelain inlays, a butt joint or butt-type cavosurface margin is recommended. This design provides maximum bulk of the porcelain at the margin, which is crucial because porcelain is brittle and needs sufficient material thickness to withstand occlusal forces and prevent fracture.
