What is the hypercementosis?
Hypercementosis is a non-neoplastic condition characterised by excessive deposition of cementum on the roots of teeth. 1. It may affect a single tooth or multiple teeth. The condition is asymptomatic and is detected on radiographic examination.
What is hypercementosis and how does it happen?
Hypercementosis is excessive deposition of cementum on the tooth roots. In most cases, its cause is unknown. Occasionally, it appears on a supraerupted tooth after the loss of an opposing tooth. Another cause of hypercementosis is inflammation, usually resulting from rarefying or sclerosing osteitis.
What are the different types of hypercementosis?
| Tooth group | Hypercementosis type | |
|---|---|---|
| discrete | moderate | |
| Maxillary molars | 2 | 1 |
| Mandibular molars | 2 | 1 |
| Maxillary premolars | 1 | 1 |
What are 5 anatomical structures of the periodontium?
The periodontium is composed of four different tissue types, the gingiva, alveolar bone, cementum, and periodontal ligament, that vary in cellular composition, types, and amounts of proteins, mineralization, degree of metabolic activity, and disease susceptibility.
What does hypercementosis look like?
Hypercementosis is a nonneoplastic deposition of excessive cementum. Most frequently, there is a uniform deposition with a drumstick-like thickening of the apical third of the root. Less commonly and less well known are small focal knots or projections of excess cementum on the lateral or interradicular root surfaces.
Does hypercementosis cause pain?
The most obvious symptom would be ridges along the tooth’s apex, but there others. For instance you may feel discomfort in the tooth or a painful sensation. The gums might not be able to accommodate all the additional cementum which cuts additional strain on the tooth.
Where are Cementicles found?
A cementicle is a small, spherical or ovoid calcified mass embedded within or attached to the cementum layer on the root surface of a tooth, or lying free within the periodontal ligament. They tend to occur in elderly individuals.
What causes external root resorption?
External resorption is often caused by injuries to the mouth and teeth that cause swelling and loss of bone and tissue on and around a tooth. Such injuries may occur from prolonged use of orthodontic appliances such as braces, or from tooth grinding or tooth bleaching.
Does Hypercementosis cause pain?
What is periodontium and its components?
The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue.
What is the most important tissue of the periodontium?
Periodontal Diseases The gingiva is the covering tissue of the periodontium and offers immediate protection for the underlying tissues as well as additional attachment of the tooth.
What causes external resorption?
What does Anodontia mean?
Anodontia is a genetic disorder defined as the absence of all teeth. It usually occurs as part of a syndrome that includes other abnormalities. Also rare but more common than anodontia are hypodontia and oligodontia. Hypodontia is genetic in origin and usually involves the absence of from 1 to 5 teeth.
What is the function of cementicles?
Cementicles undergo deposition of either primary or secondary cementum. They may also show osteoclastic resorption. Occasionally they fracture, but the fragments may become united by callus. The fusion of free cementicles around the apical end is not considered as a true cementoma.
How can you distinguish between internal and external root resorption?
This radiograph is usually taken with a different horizontal angulation of 20 to 30 degrees mesial or distal. If the radiolucent area remains over the canal space, internal resorption is most likely present. Conversely, if the radiolucent area moves away from the canal space, it is most likely external resorption.
What is hypercementosis in dentistry?
Hypercementosis. Hypercementosis is an idiopathic, non- neoplastic condition characterized by the excessive buildup of normal cementum (calcified tissue) on the roots of one or more teeth. A thicker layer of cementum can give the tooth an enlarged appearance, which mainly occurs at the apex or apices of the tooth.
What are the components of liver histology?
Liver histology 1 Functions and physiology. Stroma, which is a continuation of the surrounding capsule of Glisson. 2 Structure. 3 Hepatocytes. 4 Perisinusoidal space (space of Disse) This space is situated between the layers of hepatocytes and the sinusoidal endothelial cells. 5 Vasculature. 6 Biliary tree.
How is hypercementosis differentiated from benign cementoblastoma?
Hypercementosis should be surrounded by a periodontal membrane space, which is usually thinner than the soft tissue capsule of the benign cementoblastoma, and there is no root resorption or jaw expansion with hypercementosis. Excessive buildup of tooth density material (cementum) around all or parts of tooth root
Which histologic findings are characteristic of hepatocellular cholestasis?
The liver histology may suggest the cause of the infant’s problem, but failure to make a specific diagnosis of hepatocellular cholestasis necessitates studies to determine patency of the biliary tree such as hepatobiliary scintigraphy.
