Dentin-Pulp Complex Regeneration
Published in Vincenzo Guarino, Marco Antonio Alvarez-Pérez, Current Advances in Oral and Craniofacial Tissue Engineering, 2020
Amaury Pozos-Guillén, Héctor Flores
Dentin can be classified as primary, secondary or tertiary, depending on when it was formed. Primary dentin is the regular tubular dentin formed before tooth eruption, including mantle dentin. Secondary dentin is the regular circumferential dentin formed after tooth eruption, whose tubules remain continuous with that of the primary dentin. Tertiary dentin is the irregular dentin that is formed in response to abnormal stimuli, such as excess tooth wear, cavity preparation, restorative materials and caries (Cox et al. 2002).
A Fuzzy System For Dental Developmental Age Evaluation
Published in Horia-Nicolai Teodorescu, Abraham Kandel, Lakhmi C. Jain, FUZZY and NEURO-FUZZY SYSTEMS in MEDICINE, 2017
The first module performs the fuzzification for a tooth eruption state. Its operation is based on the relationship between general data on average time for tooth eruption, the number of teeth erupted, and other crisp data such as sex and present age. The method of evaluation of the stage of eruption (eruption state) and the use of fuzzy operations are illustrated in Figure 2.
Medical devices and the pediatric population – a head-to-toe approach

An important aspect of the physical examination of the mouth requires knowledge of tooth eruption in children. Primary teeth are deciduous and will eventually be replaced by 32 secondary or permanent teeth, 16 in each jaw. The primary teeth help children chew and pronounce words. These differences influence dental treatment including orthodontic management with braces, both removable and fixed. The orthodontic management of children varies from adults and knowledge of the order and type of dentition will influence treatment plans, including braces.

Several pathological changes can arise with the permanence of third molars, one of which is the emergence of dental cysts (Campbell 2013). A dental cyst is clinically defined as a lined layer of epithelial tissues, such as a sac or pouch, in which a fluid filled with dead cells and bacteria accumulates. In Slootweg (1987, it is pointed out that pathologies, such as cysts or tumours in relation to a developing tooth are one of the three main causes of deviation from the normal pattern of tooth eruption.
