Abstract

The premature loss of a deciduous tooth may disrupt the normal development of the occlusion leading to orthodontic treatment need This prospective study aimed to assess the association between premature deciduous tooth loss and malocclusion development and consequently orthodontic treatment needA total of 110 children mean age 64 years participated in this study The children were divided into two groups an exposed group with premature deciduous tooth loss n = 56 and an unexposed group without premature deciduous tooth loss n = 54 Their clinical charts were analyzed and clinical examinations were performed according to the criteria of the Dental Aesthetic Index DAI Both groups were reassessed on average 65 years after the initial records Statistical analysis involved the chisquare test and multiple logistic regression p 0050The premature loss of maxillary molars was significantly associated with crowding p 0001 and increased overjet p = 0001 The premature loss of mandibular molars was associated with crowding in the mandibular arch p 0001 Orthodontic treatment need was associated with premature deciduous tooth loss p 0001 and the number of missing teeth p 0001 Children with premature deciduous tooth loss exhibited a greater need for orthodontic treatment than those without premature tooth loss OR = 488 95 CIThis study was funded by the Brazilian fostering agencies Coordenação de Aperfeiçoamento de Pessoal de Nível Superior CAPES Conselho Nacional de Desenvolvimento Científico e Tecnológico CNPq and Fundação de Amparo à Pesquisa do Estado de Minas Gerais FAPEMIG Providers of funding had no role in the study design data collection and analysis publishing decisions or preparation of the manuscript
