Lateral cephalometric analysis of asymptomatic volunteers and symptomatic patients with and without bilateral temporomandibular joint disk displacement [PDF]

open access: yes, 1998
Few studies of dentofacial and orthodontic structural relationships relative to temporomandibular joint (TMJ) dysfunction have been reported. We undertook this investigation to determine any correlation of orthodontic and dentofacial characteristics with

The HRAS Variant c.175G>A (p.Ala59Thr) Causes a Predominantly Ectodermal Phenotype Lacking Classic Costello Syndrome Features

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Costello syndrome (CS) is a rare dominant HRAS RASopathy characterized by curly hair, cardiac abnormalities, craniofacial anomalies, and developmental delay. HRAS codon 58, 59, and 60 variants are associated with milder phenotypes. We describe a three‐generation family with a previously unreported heterozygous HRAS variant c.175G>A (p.Ala59Thr)

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Early life functional transitions impact craniofacial morphology in osteogenesis imperfecta

open access: yesThe Anatomical Record, EarlyView.
Abstract Early life behaviors have a profound role in shaping adult craniofacial morphology. During early life, all mammals undergo the dynamic transition from suckling to mastication, a period coinciding with rapid cranial biomineralization. Osteogenesis imperfecta (OI), a genetic disorder that impacts the production of type I collagen, disrupts ...

Odontogenic Myxoma Of The Maxilla: A Clinical Case Report And Review Of Literature [PDF]

open access: yes, 2013
Odontogenic myxomas are rare benign mesenchymal  tumours of head and neck with a potential for  local infiltration and recurrence. They appear to originate from the dental papilla, follicle or periodontal ligament in mandible and less commonly the ...

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Induced Ankylosis of a Primary Molar for Skeletal Anchorage in the Mandible as Alternative to Mini-Implants [PDF]

open access: yes, 2015
Background Mesial protraction of mandibular posterior teeth requires increased anchorage to avoid undesired tooth movements. Orthodontic mini-implants have become a popular and successful way to increase skeletal anchorage in such cases.

Association between malocclusion, caries and oral hygiene in children 6 to 12 years old resident in suburban Nigeria

open access: yesBMC Oral Health, 2019
There are conflicting opinions about the contribution of malocclusions to the development of dental caries and periodontal disease. This study’s aim was to determine the association between specific malocclusion traits, caries, oral hygiene and ...

Periodontitis treatment and microbiome in a patient with FAM20A mutation: Case study of 1.5 years

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Enamel‐renal‐gingival syndrome (ERGS) is an autosomal recessive disorder caused by mutations in the FAMily with sequence similarity 20A (FAM20A) gene, and is characterized by amelogenesis imperfecta, delayed or failed tooth eruption, and periodontitis.
