Periodontics
Equilibration aims to distribute occlusal forces evenly across the dentition to
prevent excessive stress on individual teeth, thereby reducing the risk of
mobility, wear, and periodontal issues.

Radiology1. 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.

Oral PathologyMetastatic disease in the oral cavity typically occurs in the posterior mandible. This is because the bone in this area is relatively porous and has a rich blood supply, making it more susceptible to the spread of cancer cells from distant sites in the body.
