- Abstract
Introduction. Recent studies carried out in the permanent dentition revealed a wide range of terminal relationships between enamel and cement described by Choquet, characterized by not having a unique pattern around the tooth neck. This is little studied in the primary dentition. Objective. To know the frequency distribution of the cemento-enamel junction in the temporary dental organs. Methodology. In a study approved by the Research and Ethics Commission of the Faculty of Stomatology of the BUAP (registration 2019104) a probabilistic, non-random sample, stratified by sex, of 73 healthy dental organs was analyzed, with more than one third of root and any dental formula of children between three and five years of age. They were observed under an optical microscope at magnifications of 5, 10 and 20x, slices obtained with the wear technique. Microphotographs obtained with a camera integrated to the microscope were analyzed by an observer (k = .9102). Results. 180 sections were obtained from the calculated sample. The percentage distribution of the cases corresponds case 1, 41%; case 2 present in 13%; case 3, 38%; and case 4, eight percent. According to the anatomic faces, case 1 was more frequent in the mesio-vestibular face (37%), case 2 in the mesio-lingual/palatal (44%), case 3 in 35% of the mesio-vestibular faces, and case 4 in 72% of the mesio-vestibular faces. Discussion. The tissue relations between the enamel and cement of the temporary dentition present the four combinations reported by Choquet in a different frequency distribution with respect to the authors consulted. Interdigitations between cementum and enamel of the primary dentition were observed, as well as serendipiti; some sui generis characteristics in the underlying dentin. [ABSTRACT FROM AUTHOR]

El objetivo de esta investigacion fue identificar en los canales radiculares de la dentición temporal las variantes anatómicas de la cavidad dentaria pulpar. Se realizó un estudio clínico, descriptivo, transversal ex vivo, que analizó una muestra de 60 dientes temporales pertenecientes a niños mexicanos aparentemente sanos, cuya extracción se indicó por motivos terapéuticos. Los dientes fueron almacenados en agua destilada y posteriormente diafanizados. La identificación de canales radiculares se realizó por un solo observador durante dos ocasiones (k= 0,7947). Los dientes unirradiculares presentaron 50% de canales simples y laterales, 25% secundarios y 25% deltas. Los molares maxilares presentaron un 8% de canales simples en cada raíz, mientras que los molares mandibulares un 29%. Canales secundarios, paralelos y recurrentes se observaron en el 33% de los molares. El 100% de las raíces distales de molares mandibulares presentaron canales reticulares. Las fusiones radiculares se presentan en el 88% de las molares mandibulares. La anatomía de los canales radiculares de la dentición temporal es altamente compleja. The aim of this study was to identify in roots canals of deciduous teeth anatomical variants in pulpar cavity. In a clinical, descriptive, cross sectional ex vivo study was analyzed a sample of 60 deciduous teeth of healthy Mexican children. Each tooth was conserved in distillated water and were transparency with a technic modified for deciduous teeth. Identifications of root canals was made twice by a lonely observant (k= 0.7947). Simple root teeth show 50% simple and lateral root canal, 25% secondary, 25% delta. Upper molars show 8% simple canal in each root. Lower molars 29%. Secondary root canals, parallel and recurrent were identified in 33% of cases. 100% of distal roots of lower molars have reticular canals. Root fusions are presents in 88% of lower molars. In conclusion, root canals anatomy of deciduous teeth is high complex.

- Abstract
Introduction. It is considered that in the temporomandibular joint of children, the glenoid cavity is almost flat with a low prominence of the anterior or temporal condyle that allows the anterior displacement of the jaw, so that the incisors cross over is smaller and it is considered that there is no Spee curve, and its analysis is lacking. Objective. To analyze the frequency and risk association of the presence of the Spee curve in each of the terminal planes and the overbite. Material and method. In a cross-sectional, prospective and analytical clinical epidemiological study, a heterodemic and multicentric probabilistic sample stratified by sex was analyzed, from 140 sets of temporary dentition models of the child population aged 3 to 5 years, without loss of proximal walls or cavitations for caries, as well as with fractured dental organs. Were analyzed the dependent variables Spee curve, terminal plane and overbite. Results. Were tested the hypothesis of dependence of the Spee curve with respect to the type of terminal plane (c2 = 7.104, p = 0.01, Gl = 1). The prevalence rate of the presence of the Spee curve was 43.47%. Its association with the straight terminal plane is RM = 3.96 and with the deep bite it is RM = 2.89. Conclusions. The curve of Spee is present in the deciduous dentition and responds to the need to compensate the condylar trajectory that promotes the maximum intercuspidization that allows protrusive de-occlusion thanks to the anterior and condylar guides that avoid excessive pressure in the posterior area, optimizes the incisive function during the cutting action and promotes the wear of cusps and incisal edges, which is why deep bites were not found.
