Severe Angle Class III skeletal malocclusion associated to mandibular prognathism: orthodontic-surgical treatment

ABSTRACT The present case report describes the orthodontic treatment of a young adult patient (18y / 1m), Class III skeletal malocclusion, with mandibular prognathism and significant dental compensation. The canine relation was Class III, incisors with tendency to crossbite and open bite, moderate inferior crowding, and concave profile. Skeletal correction of malocclusion, facial profile harmony with satisfactory labial relationship, correction of tooth compensation and normal occlusal relationship were obtained with orthodontic treatment associated to orthognathic surgery. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements to become a BBO diplomate.

RESUMO O presente caso clínico descreve o tratamento ortodôntico de um paciente com 18 anos e 1 mês de idade, portador de má oclusão esquelética de Classe III, com prognatismo mandibular e significativa compensação dentária. A relação entre caninos era de Classe III, incisivos com tendência à mordida cruzada e mordida aberta, moderado apinhamento inferior, além de perfil côncavo. A correção esquelética da má oclusão; a harmonia do perfil facial, com relação labial satisfatória; correção da compensação dentária e relação oclusal normal foram obtidas com o tratamento ortodôntico associado à cirurgia ortognática. Esse caso foi apresentado à Diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO), como parte dos requisitos para a obtenção do título de Diplomado pelo BBO.

Reliability of subjective, linear, ratio and area cephalometric measurements in assessing adenoid hypertrophy among different age groups.

OBJECTIVE: To test the validity of four different types of lateral cephalometric radiograph (LCR) measurements as a diagnostic test of adenoid hypertrophy in different age groups of mouth-breathing children. MATERIALS AND METHODS: Eighty-six mouth-breathing children (male 54.65%, mean age 7.0 ± 2.2 years) were randomly selected from a hospital population. Adenoid obstruction of the nasopharynx was evaluated by subjective, linear, ratio, and area LCR measurements. Each measurement was compared with flexible fiberoptic endoscopy diagnosis. RESULTS: Kendall correlation coefficients for agreement between tests were ≥ 0.67 and kappa scores were substantial (≥ 0.64). Higher correlation coefficients and agreement values were found in older age groups. When the sample was stratified by age, the 3- to 5-year-old age group showed lower correlation coefficients and agreement strength for subjective, linear, and ratio measurements. The sensitivity of LCR varied from 71% (ratio) to 84% (linear). The specificity varied from 83% (linear) to 97% (ratio). The positive predictive value varied from 88% (linear) to 97% (ratio). The negative predictive value varied from 70% (ratio) to 78% (linear). The validity of each measure was different among the age groups. CONCLUSIONS: LCR is a valid method for measuring adenoid hypertrophy in children from 6 to 12 years old. The diagnosis of adenoid hypertrophy, based on LCR measurements, in children with primary dentition (3-5 years old) should be made with caution. The combination of linear and ratio LCR measurements is a reliable screening tool to determine the need for an ear, nose, and throat evaluation.

Tratamento ortodôntico interceptador de displasia óssea severa de classe III de Angle: relato de caso / Severe angle class III skeletal dysplasia interceptative approach: a case report

As más oclusões esqueléticas de classe III de Angle são consideradas alterações de difícil tratamento e reduzida estabilidade nos resultados obtidos. Uma abordagem precoce normalmente é indicada objetivando redirecionar o crescimento, favorecer uma melhor relação esquelética e dentária e propiciar uma melhora no aspecto estético do indivíduo. Esse trabalho objetiva relatar um caso clínico de uma criança portadora de severa má oclusão de classe III

Estafilococos em pessoal da área de odontologia / Staphylococci from dental personnel

Thirty dental students and five professors were cultured in nares, throat, and hands for the presence of staphylococci. Twenty-four students and two professors were colonized with staphylococci that were classified as S. aureus. Twelve students and one professor were colonized with staphylococci that produced enterotoxin. Care needs to be taken to avoid contaminating patients during dental examination, particularly during any type of surgery
