RESUMEN

Abstract Introduction: the avulsion of primary teeth is a disturbing and unexpected event. Description: this report describes the clinical case of a three-year-old child who suffered an avulsion and replantation of the primary upper central incisors at the site of the injury. The guardians sought treatment for the child at the Federal University of Minas Gerais after the replantation. Four months later, the child suffered a new trauma and the replanted teeth presented advanced mobility, root resorption and fistula. The clinical conduct was extraction and rehabilitation with a fixed esthetic maintainer. Discussion: the literature describes two treatment options for avulsion of primary incisors: replantation and non-replantation. According to a recent systematic review, the difficulty in obtaining a consensus regarding the best clinical conduct is due, in part, to the scarcity of publications that present not only follow-ups with clinical success, but also with failures. The outcomes of replantation can be influenced by several factors. The time elapsed between replantation and splinting, and the new episode of trauma, negatively influenced the prognosis in the present case, leading to failure. Replantation of primary incisors is not yet evidence-based treatment. Therefore, this option must be chosen with caution and in ideal situations. It requires constant clinical and radiographic monitoring for evaluation of outcomes.

Resumo Introdução: a avulsão de dentes decíduos é um evento perturbador e inesperado. Descrição: o presente relato descreve o caso clínico de uma criança de três anos que sofreu avulsão e reimplante dos incisivos centrais superiores decíduos no local do acidente. Os responsáveis procuraram atendimento para a criança na Universidade Federal de Minas Gerais após reimplante. Quatro meses depois, a criança sofreu novo trauma e os dentes reimplantados apresentavam mobilidade avançada, reabsorção radicular e fístula. A conduta clínica foi extração e reabilitação com mantenedor estético fixo. Discussão: a literatura descreve duas opções de tratamento para avulsão de incisivos decíduos: o reimplante e o não reimplante. De acordo com revisão sistemática recente, a dificuldade de se obter um consenso sobre a melhor conduta clínica se deve, em parte, à escassez de publicações que apresentem não apenas acompanhamentos com sucesso clínico, mas também com falhas. O reimplante pode ser influenciado por vários fatores. O tempo decorrido entre o reimplante e a contenção, e o novo episódio de trauma, influenciaram negativamente o prognóstico do presente caso, levando ao insucesso. O reimplante de incisivos decí- duos ainda não é um tratamento baseado em evidências. Portanto, essa opção deve ser escolhida com cautela e em situações ideais. Requer monitoramento clínico e radiográfico para constante avaliação do desfecho.

RESUMEN

Objective: To evaluate the factors related to the time of exclusive breastfeeding (EBF) in infants from Pará de Minas and Três Corações (Minas Gerais) and Brumado (Bahia), Brazil. Material and Methods: All mothers attended in public and private hospitals of these cities between June and December 2012 (n=156) were invited to answer an interview related to EBF. Data were collected: (1) at maternity ward; (2) at 4 and (3) 6 months of the infant's life. In (2) and (3), data were collected by phone. Data were recorded in the SPSS software, and descriptive analyses and association of exposure and outcome variables related to the practice of EBF were performed. The chi-square test was used, considering p <0.05. Results: The total of women was in (1) 156, (2) 104 and (3) 123, and the EBF rate was 50.0%, 39.0% and 4.8%, respectively. In (1) mothers with lower schooling level have opted for EBF more frequently. In (1), the use of bottle did not interfere in EBF; on the other hand, in (2) and (3), the use of bottle has decreased the frequency of EBF (p < 0.05). Conclusion: The ideal frequency of EBF recommended by WHO to the six months of the infant's life is not followed in the evaluated cities. In addition, EBF can be influenced by the use of bottle and maternal schooling level.
