Frenotomia lingual em bebês diagnosticados com anquiloglossia pelo Teste da Linguinha: série de casos clínicos / Lingual frenectomy in babies diagnosed with ankyloglossia through the Tongue Test: a series of case reports

Objetivo: relatar uma série de casos clínicos de frenotomia lingual em bebês diagnosticados com anquilo-glossia pelo Teste da Linguinha. Relato de casos: cinco bebês, de 0 a 2 anos de idade, foram diagnosticados nas Unidade Básicas de Saúde e na Santa Casa de Misericórdia de Sobral, Ceará, com anquiloglossia mode-rada a severa. As mães relataram dificuldades de amamentação e engasgos das crianças. Os pacientes foram submetidos a procedimentos cirúrgicos de frenotomia lingual, que foram realizados na Universidade Federal do Ceará (UFC), Campus Sobral, no Grupo de Estudos em Odontopediatria (GEOP) do curso de graduação em Odontologia. As cirurgias foram realizadas com os pacientes conscientes e sob estabilização protetora. Foi administrada apenas anestesia tópica nos pacientes menores de 1 ano e anestesia infiltrativa naqueles com faixa etária maior que 1 ano. Em seguida, foi executado um pequeno corte na porção mediana do freio lingual e, quando necessário, realizada divulsão dos tecidos adjacentes. Ao final, foi feita a limpeza do local da cirurgia com a confirmação visual da efetiva liberação da língua. Por fim, as crianças receberam atestado e as mães, recomendações pós-cirúrgicas. Além disso, as crianças foram encaminhadas para consulta com o fonoaudiólogo e foram marcadas três consultas de retorno para o acompanhamento dos casos. Considera-ções finais: a frenotomia lingual mostrou-se uma técnica cirúrgica conservadora, eficaz e segura. Os bebês apresentaram excelentes resultados pós-operatórios e encontram-se em acompanhamento multiprofissional. (AU)

Objective: to report a series of clinical cases of lin-gual frenectomy in babies diagnosed with ankylo-glossia through the tongue test. Case Reports: five babies aged 0 to 2 years were diagnosed with moderate to severe ankyloglossia in Basic Health Units and in Santa Casa de Misericórdia do So-bral, Ceará, Brazil. The mothers of the children reported difficulties in breastfeeding and gagging. The patients were submitted to surgical procedu-res of lingual frenectomy, which were performed at the Federal University of Ceará (UFC), Cam-pus Sobral, in the Group of Studies in Pediatric Dentistry of the undergraduate dental course. The surgeries were performed with conscious patients under protective stabilization. Only topical anesthesia was administered in patients younger than 1 year and infiltrative anesthesia was used for those older than 1 year. Thereafter, a small cut was per-formed on the median portion of the lingual fre-nulum and, if necessary, divulsion of the adjacent tissues was performed. At the end, the surgical site was cleaned and the effective release of the tongue was confirmed visually. Finally, the chil-dren received medical certification and the mo-thers received postoperative recommendations. In addition, the children were referred to visits with a speech therapist and three follow-up ap-pointments were scheduled. Final considerations: lingual frenectomy proved to be a conservative, effective, and safe surgical technique. The babies presented excellent postoperative results and they are under multi-professional follow-up. (AU)

An unusual case of severe primary molar infraocclusion.

Dentoalveolar ankylosis is described as the direct union between root cementum/dentin and alveolar bone. Its etiology is unknown, and conflicting opinions have been presented to explain it. Late detection of ankylosed primary teeth may cause serious problems to the occlusion and generally demands a more complex treatment approach. The purpose of this report is to present an unusual case of severe infraocclusion of the primary maxillary right second molar associated with a posterior crossbite in a 6-year-old child. The initial treatment option was tooth extraction, but the tooth resumed eruption spontaneously. After correction of the posterior crossbite and a 1-year follow-up, the tooth remained in occlusion and the permanent successor was developing without problems. From this unusual outcome, it may be concluded that further investigation of this anomaly of eruption is needed.

Obliteração do canal pulpar do incisivo central superior esquerdo de uma paciente jovem após trauma - Acompanhamento clínico-radiográfico / Pulp canal obliteration of upper left central incisor of a young patient after trauma - Monitoring clinical-radiographic

Uma das complicações tardias que podem ocorrer em dentes que sofreram trauma é aobliteração do canal pulpar (OCP). Essa condição torna o dente mais susceptível ao desenvolvimentode necrose pulpar. A conduta clínica após o diagnóstico de OCP não estábem definida. Enquanto alguns cirurgiões-dentistas optam pelo tratamento endodônticoradical, outros elegem o acompanhamento clinicoradiográfico. Esse trabalho teve comoobjetivo apresentar um caso clínico do elemento dentário incisivo central superior esquerdopermanente de uma paciente jovem de 7 anos de idade com OCP após intrusão.O tratamento de escolha foi o acompanhamento clinicoradiográfico e, 18 meses após odiagnóstico, o dente continua apresentando vitalidade pulpar. Embora, os dentes que apresentemobliteração do canal pulpar tenham maior risco de desenvolverem necrose pulpar,o tratamento endodôntico profilático, nesses casos, não deve ser uma conduta de rotina.

One of the late complications that can occur on teeth that have suffered trauma is thepulp canal obliteration (PCO). This condition makes the tooth more susceptible to thedevelopment of pulp necrosis. The clinical management after the diagnosis of OCP isnot well defined. While some dentists opt for radical endodontic treatment, others preferthe monitoring clinical-radiographic. This study aimed to present a clinical case of toothupper left central incisor of a young patient of 7 years of age with OCP after intrusion.The treatment of choice was the monitoring clinical-radiographic and, 18 months afterdiagnosis, the tooth continues to show vitality’signs. Although, teeth showing pulp canalobliteration are at greatest risk of developing pulp necrosis, endodontic prophylactictreatment in such cases should not be a routine practice.

Longitudinal clinical and radiographic evaluation of severely intruded permanent incisors in a pediatric population.

Intrusion is defined as the axial dislodgment of the tooth into its socket and is considered one of the most severe types of dental trauma. This longitudinal outcome study was undertaken to evaluate clinically and radiographically severely intruded permanent incisors in a population of children and adolescents. All cases were treated between September 2003 and February 2008 in a dental trauma service. Clinical and radiographic data were collected from 12 patients (eight males and four females) that represented 15 permanent maxillary incisors. Mean age at the time of injury was 8 years and 9 months (range 7-14 years and 8 months). Mean time elapsed to follow-up was 26.6 months (range 10-51 months). The analysis of data showed that tooth intrusion was twice as frequent in males. The maxillary central incisors were the most commonly intruded teeth (93.3%), and falling at home was the main etiologic factor (60%). More than half of the cases (53.3%) were multiple intrusions, 73.3% of the intruded teeth had incomplete root formation and 66.6% of the teeth suffered other injuries concomitant to intrusion. Immediate surgical repositioning was the treatment of choice in 66.7% of the cases, while watchful waiting for the tooth to return to its pre-injury position was adopted in 33.3% of the cases. The teeth that suffered additional injuries to the intrusive luxation presented a fivefold increased relative risk of developing pulp necrosis. The immature teeth had six times more chances of presenting pulp canal obliteration that the mature teeth and a lower risk of developing root resorption. The most frequent post-injury complications were pulp necrosis (73.3%), marginal bone loss (60%), inflammatory root resorption (40%), pulp canal obliteration (26.7%) and replacement root resorption (20%). From the results of this study, it was not possible to determine whether the type immediate treatment had any influence on the appearance of sequelae like pulp necrosis and root resorption after intrusive luxation, but the existence of additional injuries and the stage of root development influenced the clinical case outcome in a negative and positive manner, respectively.

Surgical repositioning of a traumatically intruded permanent incisor in a patient with rheumatic fever: case report.

Intrusive luxation of permanent teeth is a relatively uncommon type of injury to the periodontal ligament. However, it is one of the most severe types of dentoalveolar trauma. By definition, intrusive luxation consists of the axial displacement of the tooth into the alveolar bone, accompanied by comminution or fracture of the alveolar bone. Here we report the treatment management of a traumatically intruded immature permanent central incisor by surgical repositioning undertaken in a 10-year-old child with rheumatic fever 10 days after sustaining a severe dentoalveolar trauma. The intraoral examination showed the complete intrusion of the permanent maxillary right central incisor and the radiographic examination revealed incomplete root formation. Prophylactic antibiotic therapy was prescribed and the intruded tooth was surgically repositioned and endodontically treated thereafter. The postoperative course was uneventful, with both clinically and radiographically sound conditions of the repositioned tooth up to 3 years and 2 months of follow-up. These outcomes suggest that surgical repositioning combined with proper antibiotic prophylaxis and adequate root canal therapy may be an effective treatment option in cases of severe intrusive luxations of permanent teeth with systemic involvement.
