EndodonticsAn apicectomy (or root-end resection) is a minor surgical procedure performed to remove the apex, or very end, of a tooth's root. This procedure is typically necessary when inflammation or infection persists in the bony area around the end of a tooth after a standard root canal procedure has failed. The procedure is often followed by a retrograde filling (retrograde restoration) to seal the end of the root canal.

NEETMDSThe vastus lateralis muscle in the thigh is considered the safest and preferred site for intramuscular injections in infants and young children because it is a large, well-developed muscle with a relatively low risk of nerve or blood vessel damage. Other sites like the deltoid or gluteus maximus are generally not recommended for young children due to the risk of injury to the radial or sciatic nerves, respectively.

EndodonticsMost failures of replanted teeth are due to external resorption. This includes both inflammatory and replacement resorption: 1) Inflammatory resorption occurs due to infected necrotic pulp and damaged periodontal ligament, 2) Replacement resorption (ankylosis) occurs when periodontal ligament is severely damaged, 3) External resorption is progressive and often leads to tooth loss, 4) It is more common than internal resorption in replanted teeth, 5) Prevention involves proper handling, appropriate storage media, and prompt endodontic treatment when indicated.

Oral PathologyPagets disease of bone is most likely to be found de novo among geriatric patients as it primarily affects individuals over 50 years of age, with increasing prevalence with advancing age. It is a disease of bone remodeling that becomes clinically apparent in older adults. Central giant cell granuloma typically affects younger individuals, while hyperparathyroidism and osteopetrosis are not age-specific to geriatric patients.

EndodonticsFor avulsed tooth reimplantation, only gentle saline irrigation of both socket and root surface is recommended. Aggressive curettage damages remaining periodontal ligament cells essential for successful reimplantation.
