Early loss of deciduous anterior teeth

It presents a review of data based on literature reviews, systematics, meta-analyses and clinical studies. It aims to guide dentistry students, dentists, recent graduates and clinicians regarding the diagnosis, therapeutic decision and treatment, itself, of the early loss of deciduous anterior teeth.Apresenta uma revisão de dados com base em revisões de literatura, sistemáticas, meta-análises e estudos clínicos. Visa orientar os alunos de Odontologia, cirurgiões-dentistas, recém-formados e clínicos quanto ao diagnóstico, decisão terapêutica e tratamento, propriamente dito, da perda precoce de dentes decíduos anteriores

Occlusion development after premature loss of deciduous anterior teeth: preliminary results of a 24-month prospective cohort study

ABSTRACT Objective: This study aimed to evaluate occlusion development after premature loss or extraction of deciduous anterior teeth, by means of a prospective cohort study. Methods: Fifteen infants and children aged 1 to 5 years old were longitudinally assessed (with loss or extraction of deciduous anterior teeth [n = 9], and without tooth losses [n = 6]). Photographs and dental casts at the baseline and after 24 months of follow-up were performed. Dental casts were scanned, and linear measurements were made on the digitalized models (missing tooth space, arch perimeter, arch length, arch width, intercanine length and intercanine width). The t-test was used for groups comparisons (α = 0.05). Results: Individuals’ mean age at baseline was 2.93 (± 1.18) years. No statistically significant differences were observed in the missing tooth space in the group with tooth loss during the 24 months of follow-up (p > 0.05). Arch perimeter, arch length, arch width, intercanine length and intercanine width did not show differences between the groups (p > 0.05). Qualitative photographic evaluation revealed other changes in the dental arches and occlusion, such as exfoliation and eruption of deciduous teeth, eruption of permanent teeth, self-correction or establishment of malocclusion, among others. Conclusion: The results suggest that the premature loss of deciduous anterior teeth does not affect the perimeter, length and width of the dental arches; however, other alterations that lead to malocclusion could be established
