Developmental defects of teeth

Description The average length of time for prenatal development to complete is 38 weeks from the date of conception.

Developmental defects of teeth

Endodontics is a specialty in dentistry and oral surgery that is concerned with the prevention, diagnosis and treatment of diseases of the pulp-dentin complex and their impact on associated tissues.

Physiological formation of the apex of a vital tooth Pulp PU: Soft tissue in the pulp cavity Odontoblasts: Cells of mesenchymal origin that line the outer surface of the pulp and whose biological function is formation of dentin dentinogenesis Predentin: Unmineralized dentin matrix produced by odontoblasts Dentin: Mineralized tissue surrounding the pulp and containing dentinal tubules which radiate outward from the pulp to the periphery Primary dentin: Dentin produced until root formation is completed e.


Dentin produced after root formation is completed Tertiary dentin: Dentin produced as a result of a local insult; can be reactionary produced by existing odontoblasts or reparative produced by odontoblast-like cells that differentiated from pulpal stem cells as a result of an insult Sclerotic dentin: Transparent dentin characterized by mineralization of the dentinal tubules as a result of an insult or normal aging Periapical PA: Pertaining to tissues around the apex of a tooth, including the periodontal ligament and the alveolar bone Fracture FX: Pulpal mineralization resulting in regional narrowing or complete disappearance of the pulp cavity Hypercementosis HC: Acute or chronic inflammation of the periapical tissues characterized by localized accumulation of suppuration Osteosclerosis OSS: Excessive bone mineralization around the apex of a vital tooth caused by low-grade pulp irritation asymptomatic; not requiring endodontic therapy Condensing osteitis COO: Excessive bone mineralization around the apex of a non-vital tooth caused by long-standing and low-toxic exudation from an infected pulp requiring endodontic therapy Alveolar osteitis AOS: Inflammation of the alveolar bone considered to be a complication after tooth extraction Osteomyelitis OST: Localized or wide-spread infection of the bone and bone marrow Osteonecrosis OSN: Localized or wide-spread necrosis of the bone and bone marrow Phoenix abscess: Acute exacerbation of chronic apical periodontitis Intraoral fistula IOF: Procedure involving the placement of a medicated material over an area of near pulp exposure Direct pulp capping PCD: Procedure performed as part of vital pulp therapy and involving the placement of a medicated material over an area of pulp exposure Vital pulp therapy VPT: Procedure to promote apical closure of a nonvital tooth Standard orthograde root canal therapy RCT: Removal of the apex of a tooth; also called root end resection Retrograde filling: Repositioning of a displaced tooth Interdental splinting IDS:Developmental enamel defects in primary teeth have been found at least twice as frequently in children with cerebral palsy or mental retardation as in control children, and frequently also in children with sensori-neural hearing deficits.

Dental anatomy is a field of anatomy dedicated to the study of tooth structure.

Developmental defects of teeth

The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does anatomy is also a taxonomic science as it is concerned with the naming of teeth and their structures. This . In a similar vein to birth defects or congenital conditions like heart abnormalities, spina bifida or cleft palate, children’s teeth too can encounter problems when they are forming inside the.

Developmental defects of teeth

A birth defect, also known as a congenital disorder, is a condition present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental.

Fixed orthodontics course Notes

The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which there are . • Teeth outside cleft area have greater prevalence of developmental defects (enamel hypoplasia, microdontia, macrodontia, fused teeth) • Complete alveolar clefts often associated with supernumerary teeth in premaxilla.

Rabbit incisors & cheek teeth are called aradicular hypsodont teeth which grow or erupt continuously & is held in balance by dental abrasion from chewing a diet high in fiber.
