For regular calcification, the pulp stones are smooth, round or ovoid with concentric laminations. It is commonly found in the coronal pulp. As for irregular calcifications without laminations, pulp stones may have the shape of rods or leaves and the surface is rough. It is more common in the radicular pulp.
The pulp is the neurovascular bundle central to each tooth, permanent or primary.It is composed of a central pulp chamber, pulp horns, and radicular canals. The large mass of the pulp is contained within the pulp chamber, which is contained in and mimics the overall shape of the crown of the tooth. [2]
Pulp canal obliteration (also termed pulp chamber obliteration [1] or root canal obliteration) [1] is a condition which can occur in teeth where hard tissue is deposited along the internal walls of the root canal and fills most of the pulp system leaving it narrowed and restricted. [2]
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. [1] [2] They tend to occur in elderly individuals. [3] [4] There are 3 types: [5] [6] Free cementicle – not attached to cementum [5]
Anatomical deviations preventing access or preparation of canal, including root-canal calcification, pulp stones, severely curved roots, bifurcations, secondary roots, lateral canals, delta apexes, internal and external resorption resistant to conventional treatment and an incomplete apex, may prevent the complete cleaning and preparation of ...
If the pulp becomes totally necrosed the resorption will cease unless lateral canals are present to supply osteoclasts with nutrients. If the condition is discovered before perforation of the root has occurred, endodontic therapy (root canal therapy) may be carried out with the expectation of a fairly high success rate. Removing the stimulus ...
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Preventive efforts can limit pathology occurring within the pulp, which may render future endodontic procedures less challenging, with better outcomes. Challenges are associated with root canal treatment of teeth affected by DI due to pulp chamber and root canal obliteration, or narrowing of such spaces.
