“…The enamel of the clinical crowns typically appears unaffected, requiring radiographic examination to recognize the condition. Brusevold et al reported that the molars in two of their cases demonstrated demarcated opacities. These malformations most commonly involve the permanent first molars; however, primary second molars, permanent incisors, and rarely other teeth have been reported to also be affected .…”

“…Since its initial description by Witt et al and the subsequent larger cases series by Lee et al, several reports and case series have been published documenting additional MIM cases . In the largest case series to date, Wright et al referred to this new dental phenotype as molar root‐incisor malformation.…”

“…Unlike the normally unremarkable clinical crowns of affected molar teeth, involvement of the permanent central incisors shows a cervical coronal defect or notch in the enamel . The affected incisors can also show interproximal constrictions …”

“…One may ask why it took until 2014 to describe this entity. Like Witt et al, Brusevold et al also suggested that patients could also have been diagnosed with a severe resorptive process instead of the correct diagnosis of MIM. Case 1 in our series was submitted with the clinical impression of root resorption.…”

“…Later, Lee et al described 12 cases of this dental abnormality, which they named molar‐incisor malformation (MIM). Since its initial description, several reports and series have documented additional MIM cases involving the permanent first molars, permanent central incisors, and also other teeth …”

Background Molar‐incisor malformation (MIM) is a recently described dental abnormality. While MIM mimics dentin dysplasia, it presents in a localized pattern. Furthermore, it is speculated that MIM is caused by significant early‐life medical history. Aim The purpose of this study is to present a series of MIM cases and compare the findings with the literature. Design An extensive search of all published cases of MIM in the English‐language literature was conducted. Additionally, an institutional review board‐approved retrospective search was performed within the University of Florida oral pathology biopsy service archives. Radiographic consultation cases were also included. Cases lacking radiographs were excluded. Results Seventy‐nine cases were identified in the literature, and eight cases were identified in our retrospective search. All but one case involved the permanent first molars. The average age at diagnosis was 9 years. Many patients reported significant early‐life medical histories. Conclusions MIM usually affects the permanent first molars and may be linked to early‐life medical conditions or interventions. Oral healthcare providers, especially paediatric dentists, should be aware of MIM to avoid misdiagnosing it as dentin dysplasia. Long‐term follow‐up studies with thorough medical history documentation are essential to understand the pathogenesis and aetiology and to create treatment guidelines.

Dental anomalies occur frequently in a number of genetic disorders and act as major signs in diagnosing these disorders. We present definitions of the most common dental signs and propose a classification usable as a diagnostic tool by dentists, clinical geneticists, and other health care providers. The definitions are part of the series Elements of Morphology and have been established after careful discussions within an international group of experienced dentists and geneticists. The classification system was elaborated in the French collaborative network "TÊTECOU" and the affiliated
