This risk is especially high in young patients with large pulp chambers. Tooth autotransplantation
Autotransplantation involves the removal of a tooth from one socket and relocating to another socket in the same individual. If done successfully, it is able to ensure stable alveolar bone volume as there is continuous stimulation of the periodontal ligament. Implant supported tooth replacement
Placing dental implants has proven to be a predictable and reliable method of treating hypodontia, along with bringing excellent aesthetic results. Implant placement should be delayed until jaw growth in an individual is complete. One limitation of implant placement would be the need for a sufficient amount of bone volume, which if not met, may affect the positioning of the implant. However, bone grafting can be carried out to overcome this. Epidemiology
Hypodontia is less common in the primary dentition, with reported prevalence rates ranging from 0.5% in the Icelandic population to 2.4% in the Japanese population. In the primary dentition the teeth reported as most likely to be missing are the lateral incisors, both maxillary and mandibular. If a deciduous tooth is missing this will increase the risk of an absent successor.In the permanent dentition third molars are most commonly absent, and one study found prevalence rates of between 20–22%. When third molars are ignored the prevalence rate for each tooth varies from study to study. In Caucasian studies mandibular second premolars and maxillary lateral incisors are most often absent. Several UK studies have found the lower second premolar to be most commonly absent.
Nitroglycerin, also known as glyceryl trinitrate (GTN), is a medication used for heart failure, high blood pressure, anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart (angina) or due to the recreational use of cocaine. This includes chest pain from a heart attack. It is taken by mouth, under the tongue, applied to the skin, or by injection into a vein.Common side effects include headache and low blood pressure. The low blood pressure can be severe. It is unclear if use in pregnancy is safe for the baby. It should not be used together with medications within the sildenafil (PDE5 inhibitor) family due to the risk of low blood pressure. Nitroglycerin is in the nitrate family of medications. While it is not entirely clear how it works, it is believed to function by dilating blood vessels.Nitroglycerin was written about as early as 1846 and came into medical use in 1878. It is on the World Health Organizations List of Essential Medicines. The drug nitroglycerin (GTN) is a dilute form of the same chemical used as the explosive, nitroglycerin. Dilution makes it non-explosive. In 2019, it was the 184th most commonly prescribed medication in the United States, with more than 3 million prescriptions. Medical uses
Nitroglycerin is used for the treatment of angina, acute myocardial infarction, severe hypertension, and acute coronary artery spasms. It may be administered intravenously, as a sublingual spray, or as a patch applied to the skin.
