The ideal age for examination is when the child is 8 years old - the age where all permanent first molars and most of the incisors are erupted. The permanent first molar will also still be in a comparatively sound condition without excessive post-eruption breakdown. Judgements of each individual teeth should be recorded, aiding the correct diagnosis of the condition. There is currently a lack of standardisation in the scoring system and severity indices used to record the diagnosis of MIH. Various systems commonly employed in studies include:

Modified Defect of Dental Enamel (DDE) Index: This set of criteria allows for enamel defects to be detected, enabling a distinction between demarcated and diffused opacities. European Academy of Paediatric Dentistry (EAPD) judgement criteria: This set of criteria was developed in 2003 to standardise classifications for use in epidemiological studies. However, while it allows the categorisation of the enamel condition, it does not address the severity of the enamel condition. Molar Hypomineralisation Severity Index (MHSI): This set of criteria has been developed to address deficiencies in indices concerning the severity of hypomineralisation. It is based on both the clinical characteristics of hypomineralised defects and the EAPD judgement criteria. It was found to be effective in guiding the clinical management of children by predicting treatment undertaken for affected permanent first molars. Ghanim et al index: The index combines principles of the EAPD judgement criteria and DDE index in order to grade the clinical status, amount of tooth surface area affected, and other enamel defects comparable to MIH.
A self-limiting spontaneously occurring form of torticollis with one or more painful neck muscles is by far the most common (stiff neck) and will pass spontaneously in 1–4 weeks. Usually the sternocleidomastoid muscle or the trapezius muscle is involved. Sometimes draughts, colds, or unusual postures are implicated; however, in many cases, no clear cause is found. These episodes are commonly seen by physicians.Most commonly this self-limiting form relates to an untreated dental occlusal dysfunction, which is brought on by clenching and grinding the teeth during sleep. Once the occlusion is treated it will completely resolve. Treatment is accomplished with an occlusal appliance, and equilibration of the dentition. Tumors of the skull base (posterior fossa tumors) can compress the nerve supply to the neck and cause torticollis, and these problems must be treated surgically. Infections in the posterior pharynx can irritate the nerves supplying the neck muscles and cause torticollis, and these infections may be treated with antibiotics if they are not too severe, but could require surgical debridement in intractable cases. Ear infections and surgical removal of the adenoids can cause an entity known as Grisels syndrome, a subluxation of the upper cervical joints, mostly the atlantoaxial joint, due to inflammatory laxity of the ligaments caused by an infection. The use of certain drugs, such as antipsychotics, can cause torticollis. Antiemetics - Neuroleptic Class - Phenothiazines
There are many other rare causes of torticollis. A very rare cause of acquired torticollis is fibrodysplasia ossificans progressiva (FOP), the hallmark of which is malformed great toes.
