Infrared Thermography in the Evaluation of Dental Socket Healing After Photobiomodulation Therapy: A Case Report.

Introduction: The aim of this article was to evaluate the efficacy of photobiomodulation therapy (PBMT) in the alveolar tissue healing process post-extraction using infrared thermography (IT). Case Presentation: A 36-year-old male patient had teeth extractions (18 and 28). Four PBMT sessions (660 nm; 2 J per tooth) were performed in the region of tooth 28 and recorded with thermographic images to compare the healing process, bilaterally. In the first two postoperative sessions, the temperature was higher (hyperradiant) on the left side (treated). After the third laser application, the left side was hyporradiant. In later session, the treated side became hyperradiant compared to the control side. The alveolus of tooth 28 showed more rapid healing than tooth 18 over a period of 60 days. Conclusion: IT can be used to detect the favorable effect of PBMT on accelerating the healing process in the alveolus within 60 days after the tooth extraction.

Barra transpalatina modificada / Modified transpalatal bar

Um tratamento ortodôntico objetivo se desenvolve atrelado a metas de controle dos molares superiores. Muitos são os aparelhos que objetivam sua manipulação e, dentre eles, se destaca a Barra Transpalatina (BTP), desenvolvida por Goshgarian. A partir da sua criação, foram inúmeras as modificações sofridas. A necessidade de expansão transversal, associada ao controle tridimensional dos molares superiores, foi o ponto de partida para o desenvolvimento desta Barra Transpalatina Modificada (BTM), um aparelho versátil de simples confecção e ativação.

[Is facial pattern a predisposing factor for otitis media with effusion in children?]. / O padrão facial é fator predisponente para otite média com efusão em crianças?

UNLABELLED: Abnormalities in craniofacial morphology are associated with Eustachian tube dysfunction and otitis media with effusion (OME). AIM: to evaluate the relationship between facial pattern and craniofacial growth direction, and OME in children with enlarged tonsils and adenoids (ETA). METHODS: Clinical prospective survey in 79 children (41 male and 38 female), ranging from 4 to 10 years of age, with tonsil and adenoid enlargement (Brodsky's grades III and IV). Forty children presented with OME (study group) and 39 did not (control group). Cephalometric analysis was used to determine the facial pattern. RESULTS: There was no correlation observed between facial pattern and OME (c 2 = 0.25 p = 0.88). Facial Axis was larger in the OME group (F(1.75) = 3.68 p = 0.05) and the Lower Anterior Facial height was smaller (F(1. 75) = 3.99 p = 0.05) in children with otitis media with effusion. CONCLUSIONS: There was no correlation between OME and facial pattern in children with ETA although a more horizontal facial growth direction, and a smaller lower anterior facial height was observed consistently among subjects in this group. This suggests that abnormal positioning of the eustachian tube influences the development of OME in children with ETA.

O padrão facial é fator predisponente para otite média com efusão em crianças? / Is facial pattern a predisposing factor for otitis media with effusion in children?

Anormalidades na morfologia craniofacial são associadas à disfunção da tuba auditiva e a otite média com efusão (OME). OBJETIVO: Avaliar a relação entre o padrão facial, direção do crescimento craniofacial e OME em crianças com tonsilas faríngea e palatinas aumentadas (TFPA). CASUÍSTICA E MÉTODOS: Estudo clínico prospectivo em 79 crianças (41 meninos e 38 meninas), com idades de 4 a 10 anos, com TFPA (níveis III e IV de Brodsky). O grupo de estudo foi composto por 40 crianças com OME, enquanto que o grupo controle foi composto por 39 crianças sem OME. Foi realizada análise cefalométrica. RESULTADOS: Não houve correlação entre o padrão facial e a OMS (c 2 = 0,25 p = 0,88). O grupo com OME apresentou Eixo Facial maior (F(1,75) = 3,68 p = 0,05), e uma Altura Facial Inferior menor (F(1, 75) = 3,99 p = 0,05) quando comparados ao grupo controle. CONCLUSÕES: Não houve correlação entre o padrão facial e a OME em crianças com TFPA, ainda que um padrão facial mais horizontal associado à altura facial inferior diminuída foi consistentemente observada. Isto sugere que um posicionamento anormal do tuba auditiva influencia o desenvolvimento da OME em crianças com TFPA.

The prevalence of clinical diagnostic groups in patients with temporomandibular disorders.

The aim of this study was to observe the prevalence of diagnostic groups of temporomandibular disorders (TMD) in patients who were referred or sought treatment for TMD and/or orofacial pain in a private clinic. The clinical records of 357 patients were evaluated and selected based on inclusion/exclusion criteria; the mean age was 32 years. A clinical examination was performed and the diagnosis was based on the American Academy of Orofacial Pain criteria. Results showed that 86.8% of patients were women and 93.3% of the patients presented more than one diagnosis. The most frequent chief complaint (n = 216, chi2 = 30.68, p = 0.001) and total diagnosis realized (n = 748, chi2 = 14.14, p = 0.001) were muscle related. We concluded that women seek treatment for dysfunction/disorders of orofacial structures more than men do; patients seeking specialized treatment have more than one diagnosis and muscle dysfunction is more prevalent than intra-articular disorders.

Relação da otite média secretora com o crescimento craniofacial e as características oclusais / Otitis media with effusion and dental occlusion: is there any relationship?

O objetivo deste estudo foi avaliar a morfologia/crescimento craniofacial e a oclusão dentária em pacientes (ambos sexos), entre 4 e 10 anos e aumento adenoamigdaliano com e sem otite média secretora (OMS). Utilizou-se análise cefalométrica e modelos de estudo dentários. Não foram observadas diferenças significativas entre os grupos estudados, em relação às medidas lineares e angulares adotadas, exceto, a medida correspondente ao comprimento do palato ósseo (ENA-ENP), que mostrou relação com a idade e a OMS. Não houve um tipo facial predominante. Observou-se discreta predominância de mordida profunda, mordida cruzada posterior e desvio da linha média em relação à OMS, porém sem significância estatística. A atresia maxilar pode estar associada à OMS, assim como sua redução pode estar relacionada ao crescimento e desenvolvimento craniofacial.

The aim of this study was to evaluate the craniofacial growth/morphology and dental occlusion in 100 patients (male and female) from 4 to 10 years old and tonsils and adenoid enlargement. There were two groups: with and without otitis media with effusion (OME). We used the cephalometric analyses and dental casts. It was not observed significant differences between the two groups, in relationship to the linear and angular measurements adopted, except for the measurement corresponding to the palate bone length, which had shown correlation with age and OME. It was not found a facial pattern predominance. It was observed a discreet predominance of deep bite, posterior cross bite and midline deviation to OME, however without statistical significance. The maxillary narrowing might be associated to OME as well as its reduction may be related to the craniofacial growth and development.

Perda precoce de dentes decíduos: uma apreciaçäo clínica na regiäo de incisivos superiores e caninos inferiores / Early loss of deciduous teeth: a clinical aproach about upper incisors and lower cuspids, areas

O objetivo precípuo deste trabalho é discorrer de forma didática e baseado na literatura compulsada sobre as conseqüências das perdas precoces de incisivos superiores e caninos decíduos inferiores. Com esse objetivo säo revistos inicialmente, os principais fatores etiológicos e as seqüelas gerais associadas a uma perda precoce. Segundo evidenciam as pesquisas, a perda precoce uni ou bilateral de caninos decíduos inferiores pode constituir um fator agravante de uma má-oclusäo incipiente já instalada. Por outro lado a perda de incisivo decíduo superior requer a intervençäo do profissional somente nos casos de envolvimento estético e nos esparsos casos onde há risco de fechamento de espaço e tendência à instalaçäo de hábitos bucais deletérios

Infra-oclusão submucosa de molar decíduo: relato de um caso clínico / x

A infra-oclusão de molar decíduo e uma anomalia eruptiva na qual o dente comprometido posiciona-se aquém do plano oclusal. Sua principal característica e o seu caráter eminentemente progressivo, já que o molar decíduo infra-ocluído pode, com o tempo atingir níveis submucosos e intra-ósseos. Os autores apresentam um caso clínico de infra-oclusão de molar decíduo e discutem aspectos relativos aos seus efeitos e a conduta clínica adequada em tais casos
