Natal tooth in preterm newborn: a case report

ABSTRACT Low birth weight and prematurity may be associated with delayed dental eruption in the deciduous dentition; notwithstanding this relationship, cases of preterm newborns presenting natal or neonatal teeth have been reported in the literature, although this is a rare occurrence. The objective was to present the report of natal tooth in a preterm newborn, analyzing the uniqueness of this case in contrast to the delayed dental eruption usually observed in association with prematurity. Case report: The newborn infant girl, with a gestational age of 36 weeks and 3 days and birth weight of 2,300 g, was attended to as part of the “Strategies for Oral Health Promotion for Infants” project, linked to the Pediatric Dentistry course at the Federal University of Espirito Santo. The newborn infant was referred by the neonatology and pediatric department of the university hospital as she presented an erupted tooth at birth. Clinical examination, in the region corresponding to the lower central incisors, revealed the presence of an erupted natal tooth and homologous tooth covered in gingival tissue. The periapical radiograph confirmed teeth 71 and 81. Since they were well implanted and did not interfere with breastfeeding, these teeth were retained. The mother was instructed to return if there were ulcerations in the infant’s tongue or nipple fissures, with the use of negative reporting regarding the occurrence of alterations up to two months of age. The occurrence of natal tooth teeth is rare, but they may be present in the preterm newborn, despite the association between prematurity and delayed dental eruption in the deciduous dentition.Indexing term: Infant, premature. Natal teeth. Tooth eruption.

Manifestações bucais da anemia de células falciformes em gêmeos heterozigóticos

1Universidade Cruzeiro do Sul, São Paulo/SP, Brasil. 2Universidade Federal do Espírito Santo, Vitória/ES, Brasil RESUMO| Introdução: A anemia de células falciformes (ACF) é uma doença crônica, genético-hereditária, causada por uma mutação na molécula da hemoglobina, que resulta em uma hemácia que, em determinadas condições, tem seu formato alterado para a forma de “foice”. Os indivíduos portadores apresentam períodos de crises agudas que ocorrem por obstrução de pequenos vasos sanguíneos, o que impede a circulação local, levando à hipóxia, à necrose e à dor severa, além de alterações na cavidade bucal. Objetivo: Relatar o caso clínico de gêmeos heterozigóticos, sendo um portador de anemia de células falciformes (ACF) e o outro portador de traço de anemia de células falciformes (TACF). Métodos: Duas crianças de cor parda, sexo masculino, gêmeos heterozigóticos com oito anos de idade, procedentes de Minas Gerais procuraram a Unidade Básica de Saúde de Manguinhos, localizado no município de Serra/ES, para atendimento odontológico. Na anamnese foi relatado pelo pai, que uma criança era portadora de ACF e a outra de TACF. Após a assinatura do Termo de Consentimento Livre e Esclarecido pelo responsável, foram realizados os exames clínicos e solicitados os exames complementares. Resultados: O primeiro gêmeo, T.M.S., portador de ACF, apresentou 20 kg, 116 cm de altura, e o segundo gêmeo, D.M.S., portador de TACF, 26,5 kg, com 126 cm de altura. As características clínicas e radiográficas apresentadas pelas duas crianças deste relato mostraram que a criança portadora de TACF é assintomática e não apresenta manifestação bucal da doença. Porém, a outra, com ACF, apresentou atraso no crescimento e desenvolvimento dos ossos e dentes, padrão do trabeculado ósseo reduzido e a mucosa bucal ligeiramente pálida. Conclusão: Os indivíduos com anemia de células falciformes devem ser abordados individualmente, e as condições sistêmicas devem ser avaliadas e acompanhadas por uma equipe multiprofissional. A alta prevalência das doenças bucais e o risco de complicações evidenciam a necessidade da participação do odontopediatra nesta equipe, promovendo a saúde bucal e contribuindo, dessa forma, para uma melhor qualidade de vida das crianças que apresentam a doença.

Behavior During Tooth Brushing in the Home Environment in Preterm and Full-Term Infants

Objective: To evaluate the behavior during toothbrushing of preterm and full-term infants through maternal report. Material and Methods: This study is based on secondary data collected from dental records of infants aged 12-38 months. The collected data of demographic and socioeconomic status, prematurity, tooth brushing habit and infant behavior during toothbrushing were tabulated using the SPSS-21.0 software and analyzed using descriptive and inferential statistics, carried out by the Chi-square, Fishers exact or maximum likelihood ratio statistical tests, with significant level of 5%. Results: The types of infant behavior during toothbrushing were: cooperative , participative , resistant , inflexible and independent . Variables maternal education, family income and frequency of day care attendance showed significant differences regarding the infant’s behavior (p=0.031, 0.033 and 0.004, respectively). No significant differences were found between infant’s behavior during toothbrushing and maternal occupation/study (p=0.301), primiparity (p=0.109), infants gender (p=0,233), prematurity (p=0,479), weight/gestational age ratio (p=0.231), toothbrushing before bed (p=0.83), dental biofilm (p=0,189) and presence of caries or extensive dental changes (p=0.566). Conclusion: There was no evidence that there is a difference in the behavior during toothbrushing of preterm and full term infants. Collaborative behavior was influenced by socioeconomic factors such as higher maternal schooling and family income, and in infants who attended day care.
