Dental development and physical growth are of particular interest in pediatric dentistry and orthodontics. This study evaluated these variables in patients with thalassemia major (TM). Physical growth was assessed in 54 patients (31 males and 23 females) aged 5.5 to 18.3 years and dental development was analyzed using panoramic radiographs from 39 of the 54 patients. The Demirjian system was us...

The number of new technologies emerging each year in the realm of dental caries management is growing at an exponential rate. Examining the patent literature, one can see that this growth rate will likely continue, with the outcome that dentistry will see an expanded growth in managing dental caries by risk assessment with medicinal therapeutic interventions. Restorative dentistry solutions, tr...

Background: While many dental procedures induce pulpal damage by increase the temperature, this study was established to evaluate the thermally effect of different laser methods on pulp, oral soft and hard tissues. Objectives: In this study, laser irradiation applied to measure how increased in power output can influence on dental pulp by using CT images. Methods: Ten adult New Zealand white ra...

The present meta-analysis initially evaluates the reliability of dental maturation in the identification of the circumpubertal growth phases, essentially for determining treatment timing in orthodontics. A literature survey was performed using the Medline, LILACS and SciELO databases, and the Cochrane Library (2000 to 2011). Studies of the correlation between dental and cervical vertebral matur...

Dental epithelial progenitor cells differentiate into various cell types during development of tooth germs. To study this mechanism, we produced immortalized dental epithelial progenitor cells derived from the cervical-loop epithelium of a rat lower incisor. The expression patterns of cytokeratin 14, nerve growth factor receptor p75, amelogenin, Notch2, and alkaline phosphatase were examined by...

Teeth are extremely useful in the estimation of age and are preferable over other skeletal methods As they are durable in archaeological contexts, have minimal remodeling, and the growth of permanent and deciduous teeth continues over the entire juvenile period [1,2]. Formation of deciduous teeth begins in utero at about 4 months and permanent teeth complete formation at approximately 25 years ...

The objective of this study is to analyse the diagnostic performance of the circumpubertal dental maturation phases for the identification of individual-specific skeletal maturation phases. A total of 354 healthy subjects, 208 females and 146 males (mean age, 11.1 ± 2.4 years; range, 6.8-17.1 years), were enrolled in the study. Dental maturity was assessed through the calcification stages from ...

OBJECTIVE To describe the frequency and etiology of rhinitis, oral breathing, types of malocclusion and orofacial disorders in patients treated for dental malocclusion. METHODS Patients with poor dental occlusion (n=89, 8-15 years) undergoing orthodontic treatment at the Postgraduate Orthodontics Center (Sao Paulo, Brazil) participated in the study. Rhinitis and oral breathing were diagnosed ...

Previous studies have examined tooth eruption as it relates intrinsically to body mass, brain mass, and other life history variables, and extrinsically to ecological factors (e.g., age at foraging independence, environmental risk aversion, and maternal investment). Different models have been explored wherein each of these variables impacts ontogeny. However, anthropoid and strepsirhine primates...

This study examines the relationship between measures of skeletal and dental development and socioeconomic factors in a 20th century documented skeletal sample of children from Portugal. The skeletons are of known sex and chronological age, and include other biographic data, such as cause of death. Growth in the length of the long bone is used as a measure of skeletal growth, and schedules of t...
