(From Jablonski, Dictionary of Dentistry, 1992, p676)Tooth Migration: The movement of teeth into altered positions in relationship to the basal bone of the ALVEOLAR PROCESS and to adjoining and opposing teeth as a result of loss of approximating or opposing teeth, occlusal interferences, habits, inflammatory and dystrophic disease of the attaching and supporting structures of the teeth. (From Boucher's Clinical Dental Terminology, 4th ed)Faculty, Dental: The teaching staff and members of the administrative staff having academic rank in a dental school.Cementoma: An odontogenic fibroma in which cells have developed into cementoblasts and which consists largely of cementum.Furcation Defects: Conditions in which a bifurcation or trifurcation of the molar tooth root becomes denuded as a result of periodontal disease.

Repopulation and repair is achieved by guiding the progenitor cells to reproduce in the desired location by blocking contact with surrounding tissue by use of membranes composed of synthetic or natural material that may include growth inducing factors as well.Dental Anxiety: Abnormal fear or dread of visiting the dentist for preventive care or therapy and unwarranted anxiety over dental procedures.Insurance, Dental: Insurance providing coverage for dental care.Dental Auxiliaries: Personnel whose work is prescribed and supervised by the dentist.Dental Health Services: Services designed to promote, maintain, or restore dental health.Dental Research: The study of laws, theories, and hypotheses through a systematic examination of pertinent facts and their interpretation in the field of dentistry. (From Jablonski, Illustrated Dictionary of Dentistry, 1982, p674)Decalcification, Pathologic: The loss of calcium salts from bones and teeth. Bacteria may be responsible for this occurrence in teeth. Old age may be a factor contributing to calcium loss, as is the presence of diseases such as rheumatoid arthritis.Tooth Movement: Orthodontic techniques used to correct the malposition of a single tooth.Dental Care for Aged: The giving of attention to the special dental needs of the elderly for proper maintenance or treatment.
