Clinical and x-ray oral evaluation in patients with congenital Zika Virus

Abstract Objective: The aim of this study was to investigate possible malformations in the soft, bone and/or dental tissues in patients with congenital Zika Virus (ZIKV) by clinical and x-ray evaluation. Methodology: Thirty children born with ZIKV and 30 children born without ZIKV (control group) were included in the study. Patients were evaluated over 24 consecutive months according to the variables: sex, age, cleft palates, soft tissue lesions, alveolar ridge hyperplasia, short labial and lingual frenums, inadequate posture of the lingual and perioral muscles at rest, micrognathia, narrow palatine vaults, changes in the teeth shape and/or number, sequence eruption, spasms, seizures and eruption delay were evaluated. Chi-square test, Student's t-test and nominal logistic regression were used (p<0.05). Results: Among the 30 babies examined, the mean age of the first dental eruption was 10.8±3.8 with almost two-thirds of the children (n=18, 60%) experiencing eruptions of their first tooth after 9 months of age, nine children (30%) had inadequate lingual posture at rest, more than half of the children (n=18, 60%) had short labial or lingual frenums. ZIKV babies showed a high prevalence of clef palate (p<0.001), inadequate lingual posture at rest (p=0.004), micrognathia (p=0.002), changes in the shape and/or number of teeth (p=0.006), alteration in sequence of dental eruption (p<0.001) and muscles spasms (p=0.002). The delay eruption was associated with inadequate lingual posture at rest (p=0.047), micrognathia (p=0.002) and changes in the shape and/or number of teeth (p=0.021). The delayed eruption (p=0.006) and narrow palatine vaults (p=0.008) were independently associated with ZIKV. Moreover, female patients showed the most narrow palatine vaults (p=0.010). Conclusions: The children with ZIKV showed a greater tendency to have delayed eruption of the first deciduous tooth, inadequate lingual posture and short labial and lingual frenums.

Características morfológicas encontradas na cavidade oral de neonatos: revisão de literatura / Morphological characteristics found in the oral cavity of newborns: a literature review

Objetivo: revisar a literatura sobre as característicasmorfológicas da cavidade oral de recém-nascidos. Revisãode literatura: as profissões da área de saúde estãocada vez mais voltadas para um acompanhamentoprecoce do indivíduo, iniciando-se antes mesmo donascimento ou nos primeiros dias de vida da criança.Sendo assim, recém-nascidos apresentam na cavidadeoral características peculiares da sua fase de desenvolvimentoque podem trazer dúvidas para os pais e/ouresponsáveis. As principais variações da cavidade oralde recém-nascidos envolvem tecidos duros e tecidosmoles. Considerando o posicionamento dos maxilares,as alterações mais comuns são: mordida aberta anterior,sobremordida e mordida topo a topo. Em relação aos tecidosmoles, o contorno dos lábios dos recém-nascidosse apresenta triangular e, com a amamentação constante,forma-se um aumento de volume na linha média dolábio superior. Considerações finais: além de ser necessárioque os profissionais da área tenham conhecimentodas características morfológicas da cavidade oral dosrecém-nascidos, também é imprescindível que estessaibam diagnosticar possíveis anormalidades e, quandohouver necessidade, indicar tratamento adequado.

Objective: to review the literature on the morphological characteristics of the oral cavity of newborns. Literature review: health professions are increasingly focused on the early follow-up of individuals, starting even before birth or during the first days of life of the child. Therefore, the oral cavity of newborns presents characteristics particular to their development phase, which may cause doubts to parents and/or caregivers. The major variations of the oral cavity of newborns involve both hard and soft tissues. Considering the positioning of the jaws, the most common changes are anterior open bite, overbite, and edge-to-edge bite. Regarding the soft tissues, the contour of the lips of newborns is triangular and constant breastfeeding causes an increase of volume formed in the midline of the upper lip. Final considerations: therefore, health professionals are required not only to understand the morphological characteristics of the oral cavity of newborns, but it is also essential that they are able to diagnose potential abnormalities and to indicate appropriate treatment when necessary.

Frenectomia labial pela técnica de reposicionamento cirúrgico proposta por Chelotti / Labial frenum by chirurgic replacement technic proposed by Chelotti

O freio labial superior, localizado entre os incisivos centrais superiores, é uma estrutura anatômica fina e triangular com base voltada para apical e estendendo-se do tubérculo do lábio superior até o processo alveolar. Quando, ao se tracionar o lábio para frente, para baixo e lateralmente com o objetivo de manter o freio tenso, ocorre uma isquemia tecidual, a intervenção cirúrgica está indicada, obedecendo a princípios da necessidade e oportunidade cirúrgica, principalmente no paciente infantil. A proposta deste trabalho foi apresentar um caso clínico de paciente com oito anos de idade, gênero masculino, que apresentou ao exame clínico freio tetolabial persistente que, ao ser tracionado, produzia isquemia na papila palatina, além da presença de diastema interincisal. O tratamento proposto foi o reposicionamento cirúrgico do freio. Concluiu-se que a técnica proposta contribuiu para o fechamento espontâneo do diastema e preservou as características anatômicas, funcionais e estéticas do freio labial superior.(AU)

The upper labial frenum, between maxillary central incisors, is a thin and triangular anatomical structure which base is faced to the apex extending from the upper labial tubercle until the alveolar process. When the upper lip is pulled to keep its tense, and blanches through to the palatal papilla, this seems to be an indication for its removal, regarding the principles of surgery needs and opportunity, mainly in young patient. Patient with eight years old, male, had abnormal frenum that when was pulled, blanched through to the palatal papilla, besides the midline diastema. In the RX no alteration was observed and we confirmed that midline diastema theory it was a result of abnormal frenum. The proposed treatment was a frenum replacement surgery. This technic had cooperated to the diastema naturally closure and had preserved the anatomical, functional and aesthetics characteristics of the upper labial frenum.(AU)

Surgical Management of Aberrant Labial Frenum Using Modified Z-Frenuloplasty: A Case Report.

Frenum is a mucous membrane fold that attaches lips and cheek to the alveolar mucosa, gingiva, and the underlying periosteum. The maxillary frenum can contribute to esthetic problems and can compromise the orthodontic outcome in cases of midline diastema, thus leading to treatment relapse. In addition to this, it may jeopardize the health of the gingival, when it is attached too tightly to the gingival margin, by interference in the plaque control or owing to the muscle pull. These situations can be managed with the help of frenectomy. The presenting case report demonstrates the frenectomy of an anomalous labial frenum in a 20-year-old male using modified Z-frenuloplasty technique.

Frenillo labial superior doble / Double frenulum of the superior lip

El frenillo labial superior doble no sindrómico es una anomalía del desarrollo que no hemos encontrado reportada en la revisión bibliográfica realizada. Se presenta una niña de 11 años de edad que fue remitida al servicio de Cirugía Maxilofacial del Hospital Eduardo Agramonte Piña , de Camagüey, por presentar un frenillo labial superior doble de baja inserción. Se describen los síntomas clínicos asociados a esta anomalía y el tratamiento quirúrgico utilizado para su solución: una frenectomía y plastia sobre la banda muscular frénica anormal que provocaba exceso de tejido en la mucosa labial. Consideramos muy interesante la descripción de este caso, por no haber encontrado reporte similar en la literatura revisada

Non-syndromic double frenulum of the superior lip is a developmental anomaly that was not found as reported in our literature review. This is the case of an eleven-years old girl who was referred to the maxillofacial surgery service of Eduardo Agramonte Pina hospital in Camaguey, with a diagnosis of double frenulum of the superior lip of low insertion. The clinical symptoms linked to this anomaly and the surgical treatment applied to this case were described in this paper: frenectomy and frenoplasty upon the abnormal muscular band of the frenulum that brought excessive amount of tissue in the lip mucosa. The description of this case was considered to be very interesting since no similar report had been found in the reviewed literature

Oral abnormalities in the Ellis-van Creveld syndrome.

Ellis-van Creveld (EvC) syndrome is an autosomal recessive disorder, mainly affecting the ectodermal components such as, enamel, nail, and hair. The gene for EvC syndrome is located on chromosome 4p16. Patients with EvC syndrome characteristically presents with congenitally missing teeth, abnormal frenal attachment, microdontia, and hexadactyly.
