Molar‐incisor‐malformation in a paediatric cancer patient: Case report

Abstract

AimTo report a case of molar‐incisor‐malformation (MIM) in a 7‐year‐old boy with a history of congenital infantile fibrosarcoma of the upper chest, which was surgically treated, without adjuvant radio/chemotherapy.Material and MethodsThe boy presented with mobility and pain on percussion of the permanent mandibular first molars. The radiographic features were suggestive of MIM. Both teeth were extracted and processed for conventional light microscopic examination and non‐decalcified ground sections.ResultsThe microscopic features confirmed the diagnosis of MIM. Regular follow‐up was recommended.ConclusionsMedical interventions during hospitalization for cancer treatment, other than chemo/radiotherapy, may cause MIM by adversely affecting the function of Hertwig's epithelial root sheath. Regular dental screening in paediatric cancer patients may reveal more MIM cases and help in elucidating its pathogenesis.

Interdisciplinary endodontic treatment of a Molar-Incisor Malformation-affected molar using a 3D printing model based on cone-beam computed tomography: A case report and literature review

“…clinical outcomes in all of treated teeth, positive radiographic outcomes in 85.7% of endodontically treated teeth (Table 3). Study ratings "Excellent" in 8 studies (32%) [11][12][13][14][15][16][17][18], "Fair" in 13 (52%) [2,[19][20][21][22][23][24][25][26][27][28][29][30], and "Poor" in 4 [31][32][33][34] (16%) (Table 4).…”
