Diagnosis of<unk> 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. For a dental specialist to begin the process of diagnose a patient with<unk>  there needs to be clear signs that there is an abnormality in regards to the size of the tooth in reference to surrounding teeth and average tooth sizes. This is done by noting any disproportions between the teeth and the maxilla. In general, when a patient is seen to have a tooth that is more than two standard deviations larger than the average for their age and gender, it is a major indication of<unk> at play; this is done using X-rays and can help indicate<unk> of teeth that have already erupted as well as those that are unerupted. As is customary for the identification of most dental anomalies of tooth morphology, radiographic investigation is done following the physical examination. Level 1 radiographic examination for suspected<unk>  however, should only be done after considering the patient's medical records (positive medical history of congenital syndromic conditions related to genetic disorders), the clinical signs and symptoms (the enlarged tooth shape/size), as well as the risk/benefits of exposure to harmful radiation. A specialist may also recommend a different type of radiographic investigation, orthopantomography and intraoral radiography, as a suitable imaging technique. This allows for the imaging of both jaws in a single two-dimensional image as well as reduced radiation; this is reserved for cases where level 1 radiographic investigations are unable to provide adequate information. Additionally, when two-dimensional imaging like the recommendations previously mentioned are unable to provide enough clear information regarding the anatomical relationship of the<unk> affected tooth with surrounding anatomical structures, the use of CBCT is recommended. 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. Using these imaging techniques, dentists will be able to make an accurate diagnosis of<unk> as well as the type of<unk> the patient suffers from. Types of<unk> True generalized In true generalized<unk>  all teeth grow in larger than normal. This is a symptom of rare genetic disorder cases of growth hormone excess called pituitary gigantism. Other patients may have a disease called Rabson-Mendenhall syndrome which predisposes to generalized<unk>  This causes insulin resistance and is an autosomal recessive disorder. Relative generalized All teeth appear slightly larger than normal; usually, the jaws are smaller than average. It is sometimes called "pseudomacrodontia", as small jaws give the illusion that the teeth are abnormally large. Genetics play a major role in this type of<unk>  offspring inherit small jaw size from one parent and relatively large teeth from the other parent. Single tooth A single tooth is larger than the rest. This is unusual and could be the result of fusion and germination that cause enlarged crowns.
