O cisto odontogênico botrióide é uma lesão rara caracterizada pelo aspecto multilocular típico semelhante a um cacho de uvas. A possibilidade de essa lesão representar uma variante clínica do cisto periodontal lateral é fonte de discussão e indefinição entre diversos autores. O presente trabalho relata um caso desse polêmico cisto odontogênico e apresenta considerações relacionadas aos seus aspectos etiopatogênicos, diagnósticos e terapêuticos.

The botryoid odontogenic cyst is a rare asymptomatic lesion characterized by its typical multilocular aspect similar to a bunch of grapes commonly affecting the mandible bicuspids and canine region. The possibility of this lesion representing a clinical variation of the lateral periodontal cyst is source of discussion and doubt among many authors. Our article reports a rare case of the polemic odontogenic cyst and presents considerations related to its etiopathogenic, diagnostic and therapeutic aspects.

The objective of this study was to evaluate children's respiratory patterns in the mixed dentition, by means of acoustic rhinometry, and its relation to the upper arch width development. Fifty patients were examined, 25 females and 25 males with mean age of eight years and seven months. All of them were submitted to acoustic rhinometry and upper and lower arch impressions to obtain plaster models. The upper arch analysis was accomplished by measuring the interdental transverse distance of the upper teeth, deciduous canines (measurement 1), deciduous first molars (measurement 2), deciduous second molars (measurement 3) and the first molars (measurement 4). The results showed that an increased left nasal cavity area in females means an increased interdental distance of the deciduous first molars and deciduous second molars and an increased interdental distance of the deciduous canines, deciduous first and second molars in males. It was concluded that there is a correlation between the nasal cavity area and the upper arch transverse distance in the anterior and mid maxillary regions for both genders.
