A Novel FAM83H Truncation Mutation Disrupts Enamel Mineralization in Autosomal Dominant Hypocalcified Amelogenesis Imperfecta

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Objectives Autosomal dominant hypocalcified amelogenesis imperfecta (ADHCAI; OMIM#130900) is a hereditary enamel defect caused by truncation mutations in FAM83H, though the underlying pathogenic mechanisms remain incompletely understood. This study aimed to identify novel FAM83H mutations in a Chinese family with ADHCAI and to investigate ...

Oral and dental status in children with intestinal failure: A descriptive cross‐sectional study

Journal of Parenteral and Enteral Nutrition, Volume 50, Issue 6, Page 873-880, August 2026.
Abstract Background Children with intestinal failure often experience feeding difficulties and complex daily care needs, yet their oral and dental health remains underexplored. We aimed to describe oral and dental health characteristics in pediatric intestinal failure.

Materials Engineering by Ameloblasts [PDF]

Journal of Dental Research, 2015
Enamel is unique. It is the only epithelial-derived mineralized tissue in mammals and has a distinct micro- and nanostructure with nanofibrous apatite crystals as building blocks. It is synthesized by a highly specialized cell, the ameloblast, which secretes matrix proteins with little homology to any other known amino acid sequence, but which is ...

“An Injurious and Utterly Unfit Environment”: A Case Study Comparing Dental Evidence of Childhood Stress in Nineteenth Century Working‐Class Peoples From British and Colonial New Zealand Contexts

American Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.
ABSTRACT Objectives During the nineteenth century, the health and living conditions of many working‐class European peoples declined in association with growing industrialization and urbanization. Emigration to British colonies grew as people sought to escape such hardships.

Ultrastructural and immunohistochemical study of the influence of fluoride excess on the development of rat incisor tooth buds

Journal of Applied Oral Science, 2007
Little information is available on the pathogenesis of fluorosis during the fetal and initial postnatal period. In the present study, female rats received 0 (control), 7 or 100 ppm of sodium fluoride in drinking water, one week before breeding and ...

Ameloblastic carcinoma of maxilla

National Journal of Maxillofacial Surgery, 2012
Ameloblastic carcinoma (AC) is a rare malignant lesion with characteristic histologic features and clinical behavior that dictates a more aggressive surgical approach than that of a simple ameloblastoma. The tumor cells resemble the cells seen in ameloblastoma, but they show cytologic atypia.

The Importance of Connexin 43 in Enamel Development and Mineralization

Frontiers in Physiology, 2018
During enamel development, formation of hydroxyapatite crystals and regulation of pH in the enamel matrix require massive transport of ions. Both ameloblasts and adjacent dental epithelial cells in the stellate reticulum co-express several transmembrane ...

Small molecules direct the generation of ameloblast-like cells from human embryonic stem cells

Stem Cell Research & Therapy
Background Ameloblasts present a promising avenue for the investigation of enamel and tooth regeneration. Previous protocols for directing the differentiation of human embryonic stem cells (hESCs) into dental epithelial (DE) cells involving the need for ...

4-phenylbutyrate Mitigates Fluoride-Induced Cytotoxicity in ALC Cells

Frontiers in Physiology, 2017
Chronic fluoride over-exposure during pre-eruptive enamel development can cause dental fluorosis. Severe dental fluorosis is characterized by porous, soft enamel that is vulnerable to erosion and decay.

Ameloblastic fibrosarcoma – A rarity?

JPRAS Open, 2019
Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumour classified by the WHO (1992) as an odontogenic sarcoma and defined as "a neoplasm with a similar structure to ameloblastic fibroma (AF) but in which the ectomesenchymal component shows the features of a sarcoma." The first report of AFS was published by Heath in 1887.
