Presentation
The different amelogenesis imperfectas are challenging to diagnose and treat as they are extremely diverse in their clinical presentation and are genetically heterogeneous. [uncch.pure.elsevier.com]
This type of AI is x-linked which means that the changed gene is present on the X chromosome (one of the sex chromosomes). [diseaseinfosearch.org]
Childhood presentation of distal RTA includes vomiting, failure to thrive, metabolic acidosis, and hypokalemia. [indianjnephrol.org]
History revealed that the discolouration was present from the time of eruption of the permanent teeth. [omicsonline.org]

- Dentist
Your dentist will take X-rays both inside and outside your mouth, but usually the diagnosis can be made by visual examination. A radiographic exam can help your dentist see contrast between the enamel and dentin of your teeth. [healthline.com]
Locating a Dentist There is no national list of dentists who treat people with OI. Schools of dentistry or the dental department at major medical centers may be helpful in locating dentists who are familiar with OI and DI. [oif.org]
However, dentists conducting treatment should remember to keep it as simple as possible. [phaa.com]
Children with AI are not without malocclusions and it is important that a restorative dentist and an orthodontist are involved with the pediatric dentist in the care plan from the child’s early age. [file.scirp.org]
Dental care for patients suffering from this disease is challenging and requires a good cooperation and understanding between the dentist, the patient, and the patient’s family. [omicsonline.org]

In addition to this primary complaint, the patient also reported repeated episodes of spontaneous pain and swelling in the lower right and left back tooth region. [omicsonline.org]

- Malocclusion
Children or adults with AI are not without malocclusions, they can have crowding, impacted teeth, spacings, retained teeth, reduced vertical height due to tooth structure or even due to tooth loss 50% of AI patients with malocclusions have associated [jdrr.org]

Key Words : amelogenesis imperfecta, dental anomalies, malocclusion. Introduction Amelogenesis imperfecta (AI) is a group of hereditary defects of the enamel not associated with any other generalized defect. [blackstar.forp.usp.br]
- Tooth Loss
Patients suffering from AI are also prone to early tooth loss and/or diseases affecting the periodontal tissues. AI is classified into four types based on the nature of the enamel defect and its appearance on X-ray images. [cags.org.ae]
Children or adults with AI express varying degree of malocclusions either in the form of crowding, impacted teeth, spacing, retained teeth, reduced vertical height due to abnormal tooth structure or undue tooth loss. [jdrr.org]

Treatment
Treatment progress After discussing the treatment plan with the patient, informed consent was obtained. Treatment was done in three phases. [jdrr.org]
Talk to your doctor or orthodontist to see if you or your child has been diagnosed with this condition to find the right treatment options for you. [diseaseinfosearch.org]
In other cases, primary restoration could be done before orthodontic treatment and reassessed at the end of the treatment. [bmcoralhealth.biomedcentral.com]
Amelogenesis Imperfecta Treatment The treatment of this condition depends on the type of AI that one is suffering from. This can range from providing preventive care, such as the use of Sealants and Bonding treatment. [phaa.com]
At the moment, there is no standard treatment for amelogenesis imperfecta. Treatment depends on the type and severity of the condition. [healthline.com]
Prognosis

Etiology
Understanding the etiology of hereditary conditions affecting enamel and how the enamel differs from normal (amount and/or composition) will allow clinicians to better advise their patients and select optimal treatment approaches. [uncch.pure.elsevier.com]
This finding suggests that many additional genes potentially contribute to the etiology of AI. [ingentaconnect.com]

The genetic errors alter proteins’ structure or prevent it from being produced. As a result, teeth enamel are thin, softer, and yellowish or brownish hued. Teeth with abnormal enamel are weaker and susceptible to easy breakage. [healthmomma.com]
A mutation in any one of these genes can prevent it from making the correct protein, leading to enamel that is thin or soft. [healthline.com]
