The etiology of tooth agenesis may be related to several factors, among them, the genetic alterations that play a fundamental role in the development of this dental anomaly, so that knowledge about it helps the clinician to have a greater understanding of their patients. Thus, the aim of this study was to report the case of a nonsyndromic child, with tooth agenesis of one premolar, three first ...

Significant heterogeneity has previously been reported but with no consensus on the prevalence of dental anomalies in subjects with a cleft lip and palate (CLP), thus, the purpose of this study was to investigate the frequency of various dental anomalies in the upper dental arch in different cleft groups. Diagnostic records, i.e., panoramic, occlusal and periapical films, dental casts, and intr...

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, a congenital anomaly of the female genital tract, is characterized by vaginal agenesis, a rudimentary to absent uterus compromising the normal functions of the genital tract, thereby causing psychological trauma. This syndrome is estimated to occur in approximately 1 in every 4500 females [1]. Patients with vaginal agenesis in MRKH syndrome can be...

Central incisor, congenital absence, hypodontia, tooth agenesis. Abstract Hypodontia is the congenital absence of less than six teeth because of agenesis. The absence of teeth may be unilateral or bilateral. There are reports showing unilateral occurrence of permanent mandibular incisors. But agenesis of bilateral mandibular central incisors is not well documented in the literature and comprehe...

STATEMENT OF PROBLEM Agenesis of the maxillary lateral incisor has been linked to differences in the size of the remaining teeth. Thus, the mesiodistal space required for definitive esthetic restoration in patients with missing maxillary lateral incisors may be reduced. PURPOSE The purpose of this study was to determine whether a tooth size discrepancy exists in orthodontic patients with agen...

BACKGROUND Dental agenesis is the most common, often heritable, developmental anomaly in humans. Although WNT10A gene mutations are known to cause rare syndromes associated with tooth agenesis, including onycho-odontodermal dysplasia (OODD), Schöpf-Schulz-Passarge syndrome (SSPS), hypohidrotic ectodermal dysplasia (HED), and more than half of the cases of isolated oligodontia recently, the geno...
