Third molar agenesis as a potential marker for craniofacial deformities.

Unlabelled: The identification of clinical patterns of tooth agenesis in individuals born with craniofacial deformities may be a useful tool for risk determination of these defects. We hypothesize that specific craniofacial deformities are associated with third molar agenesis.

Objective: The aim of this study was to identify if third molar agenesis could have a relation with other craniofacial structure alterations, such as cleft lip and palate, skeletal malocclusion, or specific growth patterns in humans.

Bibliometric analysis of scientific articles published in Brazilian and international orthodontic journals over a 10-year period.

Objective: This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals.

Methods: The sample comprised 635 articles selected from two scientific journals, i.e.

Role of TRAV locus in low caries experience.

Caries is the most common chronic, multifactorial disease in the world today; and little is still known about the genetic factors influencing susceptibility. Our previous genome-wide linkage scan has identified five loci related to caries susceptibility: 5q13.3, 13q31.

Enamel formation genes influence enamel microhardness before and after cariogenic challenge.

There is evidence for a genetic component in caries susceptibility, and studies in humans have suggested that variation in enamel formation genes may contribute to caries. For the present study, we used DNA samples collected from 1,831 individuals from various population data sets. Single nucleotide polymorphism markers were genotyped in selected genes (ameloblastin, amelogenin, enamelin, tuftelin, and tuftelin interacting protein 11) that influence enamel formation.

Teething symptoms in the first year of life and associated factors: a cohort study.

Objective: To investigate the occurrence and management of teething symptoms during the first year of life and associated factors.

Study Design: 500 children were recruited at birth. Research assessments including structured interviews, anthropometric measurements and dental examination were carried out after birth, at 6 months and at one-year of age.

Application of computed tomography for supernumerary teeth location in pediatric dentistry.

Conventional radiographs provide bi-dimensional images of three-dimensional structures limiting optimal treatment planning. To overcome this deficiency, Computed Tomography (CT) has been used as a diagnostic method in Medicine and Dentistry. CT allows for supernumerary teeth location, the establishment of positional relations with other teeth, and the assessment of surrounding bone thickness; thus, facilitating surgical access and technique choice while reducing the procedure time, of great importance in pediatric dental care.

Impaction of mandibular molar by supernumerary tooth: case report.

The occurrence of supernumerary teeth in the lower molar region is rare. A prevalence of less than 2% of cases occurring in this region has been estimated. The aim of this study was to present a clinical case of a 7-year-old female patient who had a supernumerary tubercular tooth between the distal root of the primary mandibular left second molar and the impacted permanent mandibular left first molar.
