A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 18, 15 May 2026.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

An aberrant splice acceptor site due to a novel intronic nucleotide substitution in MSX1 gene is the cause of congenital tooth agenesis in a Japanese family. [PDF]

open access: yesPLoS ONE, 2015
Congenital tooth agenesis is caused by mutations in the MSX1, PAX9, WNT10A, or AXIN2 genes. Here, we report a Japanese family with nonsyndromic tooth agenesis caused by a novel nucleotide substitution in the intronic region between exons 1 and 2 of the ...

Study of rs12532, rs8670 Polymorphism of Msh Homeobox 1 (MSX1), rs61754301, rs4904155 Polymorphism of Paired Box Gene 9 (PAX9), and rs2240308 Polymorphism of Axis Inhibitor Protein 2 (AXIN2) Genes in Nonsyndromic Hypodontia

open access: yesBioMed Research International, 2019
The etiology of hypodontia is complex, in which both genetic and environmental factors can be related. The main objective of our study was to contribute to elucidating the genetic background of nonsyndromic hypodontia (NSH). In this order, we selected 97

The Homeobox Genes: Classification, Regulation, Biological Functions, and Diseases

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Overview of the homeobox gene superfamily and its pathophysiological roles. The homeobox superfamily comprises several major classes, including ANTP, PRD, TALE, LIM, POU, and others. Among these, the HOX clusters (A–D) play critical roles in embryonic development specifically in conferring cellular identity, regulating morphogenesis, and guiding axial ...

The role of Msx1 and Pax9 in pathogenetic mechanisms of tooth agenesis

open access: yesDental Journal, 2009
Background: Tooth agenesis is one of the most common developmental anomalies in human, which one or a few teeth are absent because they have never formed, may cause cosmetic or occlusal harm, while severe agenesis which are relatively rare require ...

International Registry of NKX2‐1‐Related Disorders: Clinical, Genetic, and Imaging Perspectives

open access: yesMovement Disorders, Volume 41, Issue 4, Page 889-900, April 2026.
Abstract Background NKX2‐1–related disorders result from heterozygous variants in NKX2‐1, a gene crucial for brain, lung, and thyroid development. Although movement disorders, hypothyroidism, and neonatal respiratory distress are recognized, the full phenotype and genotype–phenotype relationships remain incompletely defined.

Delayed Dental Development in Children With Non‐Syndromic Hypodontia: A Cross‐Sectional Study Using a Machine Learning Approach to Dental Age Estimation

open access: yesOrthodontics &Craniofacial Research, Volume 29, Issue 2, Page 347-356, April 2026.
ABSTRACT Objectives To investigate the influence of non‐syndromic hypodontia on radiographic dental development and to estimate dental age in children with bilateral mandibular agenesis using a machine learning approach. Materials and Methods This retrospective cross‐sectional study included 626 children aged 6–15 years (311 with dental agenesis, 315 ...

Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

Prevalence and Patterns of Permanent Tooth Agenesis in Patients With Crouzon or Apert Syndrome: A Systematic Review and Meta‐Analysis

open access: yesOrthodontics &Craniofacial Research, Volume 29, Issue 1, Page 1-11, February 2026.
ABSTRACT Crouzon and Apert syndromes are rare syndromic craniosynostoses frequently associated with craniofacial and dental anomalies, including tooth agenesis. Although individual studies have reported tooth agenesis prevalence data in specific populations, no attempts have been made to systematically synthesise these data.
