The effect of primary tooth extraction on the eruption of succedaneous premolars

Validity of different dental age estimation methods in Pakistani orthodontic patients

“…Mani et al 20 reported over-estimation of dental age by 0.75 and 0.61 years in Malay's males and females respectively. Similarly, Leurs et al 12 found dental age to be significantly ahead of chronological age by 0.4 years for Dutch males and 0.6 years for females. Sukhia et al 23 tested the applicability of the original Demirjian method in the Pakistani population.…”

“…Different stages of tooth eruption or tooth calcification have been extensively used to determine the dental age 11 . Tooth calcification stages are usually preferred as these are continuous developmental processes and are less influenced by various factors such as premature loss or prolonged retention of deciduous teeth, tooth ankylosis, ectopic positions and crowding of permanent dentition 1,12,13 .…”

Shifts in tooth maturation patterns in non‐French Canadian boys

“…The wide range of development observed for children at any given age means that chronological age often precludes precise assessment of dental maturation that can be used in predictive clinical diagnosis and subsequent treatment planning. While environmental factors play a role in tooth emergence following the premature loss or dental treatment of antecedent primary teeth [3, 4], genetic factors must also be considered [5–7]. Moorrees & Kent [8] demonstrated a remarkable similarity in timing of crown formation and root formation stages in identical twins when compared with dizygotic twins in the study of 414 pairs of twins.…”

Assessment of Dental Age of Children Aged 3.5 to 16.9 Years Using Demirjian’s Method: A Meta-Analysis Based on 26 Studies

“…Moreover, this method cannot be used with children who have not yet reached the stage of mixed dentition. In addition, this method is affected by various local factors, such as crowding, extractions, ankylosis, ectopic positions, and persistence of primary teeth [8]. Stages of tooth formation, however, are less affected by local factors and can be assessed using radiographs on a broader age range of children [9].…”
