Then, the teeth were set in seven arch models to simulate mouths in primary dentition (3 lower and 4 upper arches).
Further applications seem possible in dental anthropometry by simultaneously dealing with the full dentition as a data set.
Before cetaceans evolved aquatic adaptations, they had a fully differentiated set of teeth (heterodont dentition), including incisors, canines, premolars, and molars.
First, many studies enrolled only full sets of dentition (regardless of patients' age).
Although short-span intraoral scans have exhibited excellent accuracy, few in vivo studies have investigated the accuracy of intraoral scans on whole dentition in the clinical setting.
Our study, presenting good intra-examiner reliability in both sets of dentition, proved that CAST could be used in epidemiological studies.
By 2 years of age, a complete set of primary dentition has emerged and the head circumference, 50% of adult size at birth, has expanded to about 80% of final size.
The current understanding of the molecular mechanisms controlling tooth development has come mostly from studies in mice, which have only one set of non-replaced dentition with a diastema and are obviously different from humans with respect to tooth anatomy and development; therefore, relatively little is known about the mechanisms of tooth replacement in mammals [ 2- 5].
Labio-lingually compressed, closely-set recurved and serrated dentition both on maxillae and dentaries.
Examinations were conducted in school setting and only permanent dentition was evaluated.
The participants were clinically examined at the three outpatient clinics by a calibrated examiner, with reference to the presence of decayed, missing, and filled teeth in the permanent dentition (DMFT index) in an outdoor setting, under natural light with ball-point probes and mirrors, in accordance with the World Health Organization (WHO) recommendations for epidemiological surveys [ 28].
