The main groups of drugs involved are anti-resorptive drugs, and anti-angiogenic drugs. This condition was previously known as bisphosphonate-related osteonecrosis of the jaw ( BON or BRONJ ) because osteonecrosis of the jaw correlating with bisphosphonate treatment was frequently encountered, with its first incident occurring in 2003.
Post radiation maxillary bone osteonecrosis is something that is found more in the lower jaw (mandible) rather than the maxilla (upper jaw) this is because there are many more blood vessels in the upper jaw. [7] The symptoms of this are very similar to the symptoms of medication-related osteonecrosis of the jaw (MRONJ). Patients are in a lot of ...
Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. [1] ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. [2]
The resistance of these polymers to radiation damage can be improved by grafting or copolymerizing aromatic groups, which enhance stability and decrease reactivity, and by adding antioxidants and nanomaterials, which act as free radical scavengers. [19] In addition, higher molecular weight polymers will be more resistant to radiation. [18]
Radioresistance is the level of ionizing radiation that organisms are able to withstand.. Ionizing-radiation-resistant organisms (IRRO) were defined as organisms for which the dose of acute ionizing radiation (IR) required to achieve 90% reduction (D10) is greater than 1,000 gray (Gy) [1]
Methamphetamine users sometimes experience soreness in the joint of the jaw and dental attrition (tooth wear) due to bruxism, a common side effect of stimulant drugs. [5] This bruxism can occur continuously. [7] Chronic use of the drug might also cause trismus, the inability to open the jaw. [8]
The company promised radiantly white teeth and bacterial extraction due to the ionizing radiation of the radioactive substances. The toothpaste was considered at the time a milestone of technical achievement and was touted as a "miracle remedy". Consequential damage caused by ionizing radiation is mostly unknown.
As primary teeth are being developed, the ingestion of fluoride causes the teeth to form stronger and more resistant to cavities, although this increases the risk of dental fluorosis. [10] [11] [12] Water and milk fluoridation are two forms of systemic fluoride therapy that are effective at preventing dental cavities. [13]
