ABSTRACT
A panoramic radiograph is more likely utilized in children with high caries risk and mixed dentition, and it can be complemented by other X-rays (such as periapical and/or bitewings). This study analyzed 1359 panoramic radiographs taken over 33 years at the Pedodontics Clinic of the State University of Rio de Janeiro in order to determine the prevalence of dental anomalies in mixed dentition children. The population evaluated had 670 (49.3%) boys and 689 (50.7%) girls, ranging in age from 5-12 years, with a median age of 8 years. The total prevalence of anomalies detected was 11.72%; anodontia and supernumerary teeth were the most reported (4.63% and 3.31%, respectively). Statistical differences noted were in the presence of supernumary teeth in males (4.9%, P <.001) and the presence of anodontia in females (6.1%, P = .009). Based on these findings, a panoramic radiograph can help to analyze transitional dentition, as well as complement the clinical examination at the first dental visit of a pediatric patient with a high risk for caries.

OBJETIVO: Realizar o primeiro censo brasileiro de cirurgia refrativa. MÉTODOS: Entre agosto de 2001 e fevereiro de 2002 foram enviados questionários para 7.890 oftalmologistas brasileiros, com questões sobre aspectos demográficos, tendências, padrões de práticas, instrumentos, cuidados pré-operatórios e mercado da cirurgia refrativa. RESULTADOS: Novecentos e vinte questionários (11,67 por cento) foram devidamente respondidos. O laser in situ ceratomileuse é a técnica preferida para correção de dioptrias entre +5,00 e -7,00 D. O excimer laser mais utilizado é o Nidek® EC 5000 e o microceratótomo mais freqüente é o Hansatome. Outros aspectos como: demográficos, procedimentos, técnicas, tendências, volume cirúrgico, cuidados pré-operatórios e mercado também foram analisados. CONCLUSÃO: A partir desta pesquisa, pode-se observar e monitorar aspectos demográficos, padrões de práticas, tendências, tecnologia e mercado da cirurgia refrativa no Brasil e compará-las com outras pesquisas semelhantes em outras partes do mundo.

PURPOSE: To perform the first Brazilian refractive surgery survey. METHODS: Between August 2001 and February 2002, a questionnaire was mailed to 7890 Brazilian ophthalmologists. The questionnaire presented questions about demographic aspects, technology, instruments, market, trends, practice patterns and cost of refractive surgery. RESULTS: Nine hundred and twenty questionnaires (11.67%) were answered. LASIK is the preferred technique for correction between +5.00 and -7.00 D. The mostly used excimer laser is Nidek EC 5000, and Hansatome is the mostly used microkeratome. Others aspects like: demographic, techniques, practice patterns, trends, market, and pre-, intra- and postoperative care, were analyzed. CONCLUSION: With this survey, the Brazilian ophthalmologists can observe and monitor these aspects of refractive surgery in Brazil, and compare them with others surveys.

Dentes decíduos que tenham sofrido qualquer tipo de trauma devem ser periodicamente avaliados, para que se possa diagnosticar precocemente a ocorrência de patologia pulpar ou periapical que resulte em prejuízo para o desenvolvimento normal do dente permanente sucessor. Neste trabalho, é descrito um caso de distúrbio de desenvolvimento dos germes de incisivos superiores permanentes, que resultou em lesäo semelhante a odontoma nos centrais e hipoplasia nos laterais, e cuja causa foi, provavelmente, um traumatismo que provocou a intrusäo dos incisivos centrais decíduos, aos 16 meses de idade
