She tells Yahoo Life that a tooth is made up of minerals including hydroxyapatite, fluoride and calcium, which is why they can be used to strengthen its enamel and prevent further damage.
A root end surgery, also known as apicoectomy (apico-+ -ectomy), apicectomy (apic-+ -ectomy), retrograde root canal treatment (c.f. orthograde root canal treatment) or root-end filling, is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material.
Where the enamel (the hard outer surface of the tooth) has cavitated or even has a small breach due to tooth decay, the cavity can be enlarged with special hand instruments when necessary to enable access to the soft decayed tooth tissue. After removing as much decay as necessary, the cavity is cleaned with water, dried and filled with the HVGIC.
The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
A set of human teeth under an orthopantomogram. Tooth regeneration is a stem cell based regenerative medicine procedure in the field of tissue engineering and stem cell biology to replace damaged or lost teeth by regrowing them from autologous stem cells.
When teeth are damaged or injured in any way, as internal bleeding occurs in the pulp chamber, blood gets into the dentinal nerves and gets trapped into the pulp, staining the dentin. Post trauma, a tooth can discolour and turn black or grey within a few days and if the injury is mild the tooth may return to its original status.
Typically the tooth is lifted using an elevator, and using dental forceps, specific tooth movements are performed (e.g. rocking the tooth back and forth) expanding the tooth socket. Once the periodontal ligament is broken and the supporting alveolar bone has been adequately widened the tooth can be removed.
Once the tooth and mouth are clean an attempt can be made to re-plant the tooth in its original socket within the alveolar bone and be splinted (stabilized) by a dentist for several weeks. [15] Failure to re-plant the avulsed tooth within the first 40 minutes after the injury may result in a less favorable prognosis for the tooth. [15]
