Factores que inciden en crecimiento y desarrollo de la zona de sostén en la dentición mixta.

Abstract

Introduction: We refer to the distal space of the permanent lateral incisor and mesial of the first permanent molar as the supporting zone. The support zone is comprised of permanent canines and premolars. Objective: To analyze the factors that influence the growth and development of the support zone in the mixed dentition. Materials and methods: A descriptive, analytical and cross-sectional study was carried out in the Pediatric dentistry and Orthodontics clinic at the UCSG and a radiology center in Guayaquil. 120 panoramic radiographies of patients between 8 and 11 years of age were used. Results: A total of 50.8% of girls and 49.2% of boys were analyzed. The prevalence of interproximal caries was 27.5%. Premature exodontia was evidenced in 22.5% of the children. Regarding eruption chronology of the study group, 50% were late, 29.2% were normal and 20.8% were premature. Conclusion: In the supporting zone, interproximal caries, premature exodontia, normal, premature or late eruption are factors to be considered in the study of the growth and development of the Korkhaus supporting zone.
