Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. Initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar. Some studies have observed that ectopic teeth can be found in a variety of places around the oral cavity and also in other areas of the human body. There are records of teeth in the maxillary sinus, mandibular condyle, coronoid process, mandibular angle, orbit, palate, mentum and also the skin. The prevalence of tooth abnormalities is higher in children with cleft lip and palate compared to children without clefts. This paper presents a case report of migration of the mandibular left second premolar in a patient attending the Hospital for Rehabilitation of Craniofacial Anomalies of the University of São Paulo (HRAC/USP), Brazil. Migration of the mandibular left 2nd premolar was confirmed by 8 panoramic and 1 periapical radiographs obtained during patient's treatment between 1978 and 2002, which were available in the files of the Department of Dental Radiology of HRAC/USP. It can be assumed that distal migration of the mandibular left 2nd premolar is not associated with presence of cleft lip and palate; observation of these two events in a same patient is rare, since no similar reported cases were found in the literature.

La Incontinentia Pigmenti es una condición rara, que afecta órganos y tejidos de origen ectodérmico y mesodérmico, asociado al cromosoma X dominante. Se manifiesta en el nacimiento o más tarde, con lesiones eritematosas en la piel. Puede afectar también pelo, uñas, ojos, sistema nervioso central y dientes. Las manifestaciones dentarias presentes se parecen con aquellas encontradas en la displasia ectodérmica y en la sífilis congénita: hipodoncia, microdoncia, retraso de la dentición, malformaciones y dientes impactados. Las alteraciones dentarias que se presentan en tal caso son típicas y comprenden agenesias, dientes conoides y disturbios de la erupción.

Incontinentia Pigmenti is one of the rare conditions that affect organs and tissues of ectodermal and mesodermal origin, and is inherited as an X-linked dominant trait. It may be noticed at birth or soon after, by means of skin erythematous lesions. It may also affect hair, nails, eyes, central nervous system and teeth. Dental manifestations are similar to those observed on ectodermal dysplasia and congenital syphilis: hypodontia, microdontia, delayed tooth eruption, malformations and impacted teeth. The dental alterations presented on this case report are typical and include tooth agenesis, peg-shaped teeth and eruption disturbances. A clinical case of a girl is presented in that observes the cutaneous hiperpigmentation of the superior members and the back; and the clinical absence of several temporary teeth.

Incontinentia Pigmenti é uma condição rara, que afeta órgãos e os tece da origem ectodérmico e mesodermico, associado ao cromosoma dominante X. É pronunciado mais atrasado no nascimento ou, com os ferimentos erytematosus na pele. Pode também afetar o cabelo, pregos, olhos, sistema nervoso central e dentes. Os manifestação dentais atuais olham como com aqueles encontrados dentro ectodérmica e sífilis da displasia congênita: hipodontia, microdontia, atrasa da má formação dentarias e dentes impactados. As alterações dentais que aparecem em tal caso são típicas e agenesias de inclui dentes dos conoides e distúrbios da erupção. Um exemplo clínico de uma menina aparece em quem eu sou observado o hiperpigmentassem cutâneos dos membros superiores e da parte traseira; hipotricosis e a ausência clínica de diversos dentes decíduos.

O objetivo deste trabalho foi avaliar se os métodos de Martins e Sakima e Grave e Brown são aplicáveis para o estudo do surto de crescimento puberal (SCP) de crianças com fissuras lábio-palatais. Foram analisadas 132 radiografias carpais de pacientes do HRAC-USP, dos gêneros masculino e feminino, com a faixa etária de 7 a 17 anos, utilizando 6 radiografias de cada idade e gênero. Ambos os métodos estudam os estágios de ossificação dos ossos da mão e punho e os estágios que se encontram as epífises, através de gráficos. Com relação a este estudo, no gênero feminino, tanto para Martins e Sakima quanto para Grave e Brown, o início, pico e final do SCP ocorreram entre 9 e 10 anos, 12 anos e 15 anos, respectivamente. Da mesma forma, para o gênero masculino, Martins e Sakima e Grave e Brown mostraram médias de idade similares: 12, 14 e 16 anos para início, pico e final do SCP, respectivamente. O teste de correlação de Pearson mostrou uma alta e significativa correlação (r = 0,99 e P < 0,001) entre os métodos estudados. Em conclusão, esses dois métodos de avaliação do surto de crescimento e desenvolvimento apresentaram uma alta correlação quando aplicados na avaliação de crianças com fissuras lábio-palatais. Baseando-se na literatura e nos resultados dessa pesquisa, é possível sugerir que ambos os métodos podem ser aplicados nos pacientes com fissuras lábio-palatais para a obtenção do surto de crescimento puberal.

The aim of this study was to evaluate whether Martins and Sakima and Grave and Brown methods are useful for the study of pubertal growth spurt in children with cleft lip and palate. A total of 132 hand-wrist radiographs of patients from HRAC/USP aged 7 to 17 years old were analyzed, including girls and boys. Six radiographs of each age and gender were employed. These methods were applied to evaluating the stages of the hand-wrist ossification and epiphyseal formation, by graphic representation. The Martins and Sakima and the Grave and Brown methods revealed that the initial, peak and final stages of pubertal growth spurt occurred between 9 to 10, 12 and 15 years old, respectively, in the female gender. Similarly, in the male gender, both Martins and Sakima and Grave and Brown methods showed similar mean ages: 12, 14 and 16 years old for initial, peak and final stages of pubertal growth spurt, respectively. The Pearson's correlation test showed high and significant correlation (r = 0.99 and p < 0.001) between the methods investigated. In conclusion, the methods appeared to be highly and significantly correlated as regards the analysis of children with cleft lip and palate. Moreover, based on the literature and present results, it is possible to suggest that the two methods have shown similar pattern and may be used with equal efficiency for assessment of the pubertal growth spurt in children with cleft lip and palate.
