Non-Invasive and Holistic Approach to the Functional and Esthetic Rehabilitation of Amelogenesis Imperfecta in Young Patients: A Clinical Study.

Journal of pharmacy &amp; bioallied sciences2026 Feb

Amelogenesis imperfecta (AI) is a hereditary enamel defect that often causes sensitivity, functional limitations, and esthetic concerns in young patients. This clinical study evaluated a non-invasive and holistic approach to rehabilitation using preventive fluoride therapy, pit and fissure sealants, microabrasion, and adhesive composite restorations. Young patients with AI who underwent clinical and radiographic evaluation were the subjects of this clinical study. rehabilitation while maintaining the greatest amount of tooth structure possible. Thin composite veneers were applied using adhesive techniques in a few chosen anterior cases with a higher esthetic demand. Patients showed marked reduction in sensitivity, improved chewing comfort, and enhanced esthetic satisfaction over a six-month follow-up, with high restoration survival and notable psychosocial benefits. The findings suggest that conservative, patient-centered management can effectively restore function and appearance in AI during growth, while preserving tooth structure and supporting overall well-being.

DLX3 is a homeobox transcription factor essential for multiple organogenesis processes. Mutations in DLX3 cause trichodentoosseous syndrome (TDO), characterized by curly hair, sclerotic bone, enamel, and dentin defects as well as taurodontism. Phenotypic variability in TDO has been well documented, but its pathogenesis remains poorly understood. Here, we characterized three TDO families with distinct clinical features and identified a known DLX3 deletion (c.561_562del) and the first pathogenic splice-site variant (c.516+1_516+2insA). The proband with the splice-site mutation displayed a mesenchymal-dominant phenotype with severe dentin hypoplasia, enlarged pulp chambers, and hypertaurodontism but nearly normal enamel, whereas the mother and sister showed epithelial-dominant anomalies, including enamel hypoplasia and kinky hair. Minigene analysis demonstrated that c.516+1_516+2insA generated two aberrant transcripts encoding p.Val173Aspfs*28 and p.Arg120_Val173del. These mutant proteins localized mainly in the cytoplasm and showed markedly reduced transactivation activity. In cultured human dental pulp cells, DLX3 overexpression upregulated the odontoblastic markers DSPP, MMP20, and WNT10A. Chromatin immunoprecipitation and reporter assays further revealed that DLX3 directly activates WNT10A via a conserved enhancer (chr2:218,878,973_218,879,302) and three upstream binding sites. These findings expand the TDO mutational spectrum and suggest that differential mutant DLX3 expression may contribute to phenotypic variability, whereas disrupted regulation of WNT10A underlies dentin defects and taurodontism.

Soluble Notch agonist enables human ameloblast maturation and enamel-like tissue formation for tooth regeneration.

International journal of oral science2026 Mar 02

Enamel, the hardest mineralized material in the human body, protects the underlying living tissues, the dentin and pulp of the tooth. However, over 90% of adults have lost or damaged enamel and cannot regenerate the protective structure due to lack of enamel-producing cells, ameloblasts. iPSC-derived secretory Ameloblasts (isAM) have promise in future regenerative dentistry. Today, it is not known why iAM maturation requires intimate contact with the dentin-producing cell type, odontoblast. Here, we reveal that one of the critical signaling ligands emanating from odontoblasts for ameloblast maturation is Delta, the ligand for Notch receptor. We showed that our designed, soluble Notch agonist can induce iAM organoid maturation in an unprecedented manner, without interactions with odontoblast layer. Notably, soluble Notch agonist induces the iAM maturation to a novel, WDR72-positive mature secretory AM stage (ismAM) in our ameloblast organoid model. When transplanted under the kidney capsule of NOD-SCID mice, these ismAM organoids generated enamel-like calcified material, as confirmed by microCT analysis, marking the first demonstration that Notch-activated iAM organoids can form such tissue in vivo. This novel maturation procedure enabled us to analyze the specific requirements of DLX3 function in ameloblasts, independent of its known function in odontoblasts. We now show that DLX3, a gene associated with Amelogenesis Imperfecta, is required on a cell-autonomous manner in human ameloblasts for the expression of Enamelin, MMP20, and WDR72, a role not previously demonstrated in mouse models.

Novel MMP20 (matrix metalloproteinase 20) mutations causing hypoplastic-hypomaturation amelogenesis imperfecta.

Journal of dental sciences2026 Jan

Matrix metalloproteinase 20 (MMP20) is a proteinase essential for dental enamel formation. Mutations in human MMP20 cause autosomal recessive amelogenesis imperfecta (AI), characterized by thin and soft enamel. This study aimed to unravel the genetic causes for five families with hypoplastic-hypomaturation AI. Whole-exome analyses and Sanger sequencing were performed to identify and confirm disease-causing mutations. To evaluate the pathogenicity of identified MMP20 missense variants, immunoblotting and gelatin zymography were conducted on proteins overexpressed in HEK293T cells. All affected individuals from the five families exhibited similar dental phenotypes, including chalky-white to yellow-brown discolorations and evident dental attrition. The defective enamel was both thin and hypomineralized. Six pathogenic MMP20 variants were identified: c.289A>T (p.Lys97∗), c.547G>A (p.Asp183Asn), c.686G>A (p.Gly229Asp), c.102G>A (p.Trp34∗), c.359dup (p.Asn120Lysfs∗9), and c.954-2A>T. Among them, the first three have not been previously reported. The two missense mutations altered evolutionarily conserved amino acid residues within the catalytic domain of MMP20. Compared with the wild type, secretion of both mutant MMP20 proteins was significantly impeded, and neither displayed proteolytic activity on gelatin zymography, indicating a loss of enzymatic function. This study expands the genotypic spectrum of MMP20-associated AI and highlights two critical residues within the MMP20 catalytic domain that are essential for its secretion and enzymatic activity.

FAM20A Deficiency Drives Transcriptomic Dysregulation and Functional Impairment in Gingival Fibroblasts.

Cell proliferation2026 Feb

Amelogenesis imperfecta type 1G (AI1G), also known as Enamel-Renal-Gingival Syndrome (ERGS), is an autosomal recessive disorder caused by variants in FAM20A, encoding a Golgi apparatus protein crucial for protein processing and secretion. AI1G presents with enamel defects, nephrocalcinosis and gingival overgrowth. Building upon our previous findings demonstrating the impact of FAM20A insufficiency on deciduous dental pulp cells, this study investigated the molecular mechanisms underlying gingival fibromatosis in AI1G. RNA sequencing of gingival fibroblasts from an AI1G patient revealed widespread differential gene expression (DEG). Gene Ontology (GO) analysis demonstrated enrichment of DEGs in biological processes related to cell adhesion, differentiation, proliferation (including positive regulation and cell division), cell cycle regulation, apoptosis and signal transduction. Pathway analysis (Reactome and KEGG) further highlighted the dysregulation of signalling pathways, including Wnt, TGF-β, cell cycle, DNA replication, Rho GTPase signalling and extracellular matrix organisation. Functional assays confirmed these findings, revealing delayed initial attachment and spreading, impaired osteogenic differentiation (evidenced by reduced mineralization and downregulation of DLX5, OCN, RUNX2 and OPN), enhanced cell cycle progression and proliferation (increased colony size and proliferation rates, along with a shift from G0/G1 to G2/M phase) and suppressed apoptosis in FAM20A-insufficient fibroblasts. These results suggest that FAM20A plays a critical role in regulating fundamental processes in gingival fibroblasts, and its insufficiency contributes to the gingival fibromatosis phenotype observed in AI1G through the disruption of cell adhesion, differentiation, proliferation and apoptosis. This study proposes novel insights into the pathogenesis of AI1G and highlights potential therapeutic targets for this complex disorder.
