Macrodontia (tooth)

Generally, patients with macrodontia have one or two teeth in their mouth that is abnormally large; however, single tooth growth is seen in a number of cases as well.Two key mechanisms that are commonly referred to in scientific literature surrounding this condition is how patients suffering with pituitary gigantism exhibit macrodontia as well as those with the genetic disorder KBG syndrome.This is a rare congenital genetic syndrome that is characterized by facial dysmorphism, macrodontia of the permanent upper central incisors, and other skeletal abnormalities.[6] This gene is known to interact with nuclear receptor complexes in order to modify transcriptional activation,[6] while also having a critical role in dental, craniofacial, skeletal, and CNS development and function.In essence, the mutation of this gene leads to conditions to KBG syndrome which has symptoms such as macrodontia as a result of uncontrolled growth of these areas.[6] Diagnosis of macrodontia by a dental specialist is first obtained by simple observation, measurement, and comparison with the standard tooth size; this is then later accompanied by conducting a radiological investigation which can be done in a variety of ways.[8] The 3D CBCT imaging technique must be as targeted to the area in question as possible as to minimize the exposure of radiation to the patient while also maintaining optimal spatial resolution.[citation needed] During this treatment method, a dental specialist will use a gentle sanding device to shave and reduce the size of the tooth.[citation needed] A last-method approach to combat macrodontia is also to simply remove the affected tooth to make more space for the neighboring teeth.[citation needed] Those patients that take this route of treatment usually get the affected tooth removed and replace it with dentures or false teeth to enhance the appearance of the mouth.[12] While there is research regarding the symptoms and effects of macrodontia on patients, there is still a fundamental misunderstanding regarding the specific pathophysiological mechanisms that are exhibited which result in this abnormality.[8] There is also an abundance of information regarding treatment options that are mostly concentrated within the cosmetic branch of dentistry to fix the appearance of the teeth as well as simply removing it to halt continuous pain.There is no current clinical trials for treatment of this disease as there are a number of procedures which already exist to make the affected teeth smaller; and if all else fails, dentists can simply remove the tooth and replace it with a veneer or bridge in its place.
