Anatomy and Embryology of the Mouth and Dentition
John C Watkinson, Raymond W Clarke, Terry M Jones, Vinidh Paleri, Nicholas White, Tim Woolford in Head & Neck Surgery Plastic Surgery, 2018
There are two generations of teeth: the deciduous (primary) dentition and the permanent (secondary) dentition. In the complete deciduous dentition there are 20 teeth—five in each jaw quadrant. In the complete permanent dentition there are 32 teeth—eight in each jaw quadrant. In both dentitions, there are three basic tooth forms: incisiform, caniniform and molariform. Incisiform teeth (incisors) are cutting teeth, having thin, blade-like crowns. Caniniform teeth (canines) are piercing or tearing teeth, having a single, stout, pointed, cone-shaped crown. Molariform teeth (molars and premolars) are grinding teeth possessing a number of cusps separated by fissures. Premolars are bicuspid teeth that are peculiar to the permanent dentition and replace the deciduous molars.
Dental Trauma
Jeffrey R. Marcus, Detlev Erdmann, Eduardo D. Rodriguez in Essentials of CRANIOMAXILLOFACIAL TRAUMA, 2014
Dental injuries have been classified according to a variety of factors, such as cause, anatomy, pathology, or therapeutic considerations. The present classification is based on a system adopted by the World Health Organization in its Application of International Classification of Diseases to Dentistry and Stomatology.1 However, for the sake of completeness, it is necessary to define and classify certain trauma entities not included in the WHO system. The following classification includes injuries to the teeth, supporting structures, gingiva, and oral mucosa and is based on anatomic, therapeutic, and prognostic considerations. This classification can be applied to both the permanent and primary dentition. An illustrated glossary of terms and definitions can be found in the Appendix at the end this chapter.
Association between age at asthma diagnosis and tooth loss

This study reaffirmed that subjects who were diagnosed with asthma at a young age (0–12 years) had significantly more tooth loss due to caries than that in subjects in the other groups. An analysis of the 2007–2014 KNHANES data showed significant tooth loss due to dental caries in patients who were diagnosed with asthma before 12 years of age. Previous studies have reported associations with dental caries in asthmatics of various ages, such as before 3 years, 3–6 years, 6–10 years, 10–14 years and 12–16 years [11,19,33]. In this study, we divided the dentition phases into 0–6 years of age (deciduous dentition), 7–12 years of age (mixed dentition), adolescents and young adults. We confirmed that asthma diagnosis in patients aged ≤ 12 years showed a significant correlation (p < .01, 0–6 years; p < .01, 7–12 years) with tooth loss due to caries.
Malocclusions in primary and early mixed dentition in very preterm children

All data had been gathered and saved in electronic records as part of the normal daily practice of public health centres. One examiner collected and coded the data from the electronic dental records. In cases of deviating occlusal traits or malocclusions, the status was complemented with an orthodontic examination and/or free text message (concerning, e.g. delayed tooth eruption), and with radiographs, as needed. Data included information on the child’s gender, oral habits (non-nutritive sucking), overjet, overbite, dental and jaw relations, available space in dental arches, and orthodontic treatment history. Oral habits had been recorded in a structured way from six months to three years of age; thereafter, the situation was updated, if the habit persisted at three years or if there was any reason to suspect such a habit. Included data covered developmental stages from primary dentition to the completion of early mixed dentition. Data considering dental and occlusal relationships were always collected before any orthodontic treatment. All children having orthodontic treatment in primary dentition and their age and gender-matched pairs were excluded from the analyses in the early mixed dentition stage.
Dental and dentoalveolar dimensions in individuals with osteogenesis imperfecta

As the study group displayed a wide age-range, the available controls were grouped to better match to patients. Equal number (n = 5) of OI patients and controls were in mixed-dentition phase and their age ranged between 9.8 and 12.8 years. Median age difference between the study subjects and controls in this matched group was 0.7 years and maximum difference 0.9 years. Similarly, equal number (n = 32) of study patients and controls were in permanent dentition phase (aged between 18.8 and 74.7 years), and the median difference in age was 1.7 years (maximum difference 16.3 years). This difference in age was not expected to have an impact on the dental measurements as the approximal wear of teeth and alterations in palatal size are minimal. Loss of permanent teeth would be the only significant factor affecting dental arch measurements in later age years. The OI and the control groups did not differ in terms of number of permanent teeth missing for any reason, third molars excluded from the analysis (p > .64).
