Primary teeth show less protecting factors against root resorption

BACKGROUND Physiological root resorption differentiates primary from permanent teeth. The understanding of what protects and regulates root resorption might help to develop therapies to its control. AIM To verify the presence and distribution of ECRM and the expression of CK14, OPG, TRAP and COX-2 in the periodontal ligament (PDL) of human primary and permanent teeth. Design.  Eight primary teeth undergoing physiological or pathological root resorption and 4 permanent teeth were immunohistochemically processed for CK14, TRAP, COX-2 and OPG expression. RESULTS PDL from primary and permanent teeth showed similar morphological features; however, fewer ECRM clusters and higher immunoreactivity to CK14 were found in primary PDL. In permanent teeth, ECRM were distributed along the entire PDL tissue. Howships lacunae were found only in primary teeth, associated with the presence of TRAP-positive cells and increase in COX-2 expression. OPG expression in primary PDL was detected in nonresorptive cervical areas and in lacunae showing reparative tissue. It was observed higher expression of OPG in all permanent teeth when compared to primary specimens. CONCLUSIONS It may be concluded that PDL from primary teeth shows less ECRM clusters and lower expression of OPG. These features may be associated with lower protection against root resorption in primary teeth.

O Início do Desmame Precoce: Motivos das Mães Assistidas por Serviços de Puericultura de Florianópolis/SC para esta Prática

Objetivo: Identificar as razoes das maes de criancas de 6 a 12 meses de idade, em acompanhamento de puericultura na cidade de Florianopolis/SC, para a interrupcao do aleitamento materno exclusivo (AME) antes do sexto mes pos-parto (inicio do desmame precoce). Metodo: Estudo transversal de caracteristicas descritivas, realizado a partir de entrevistas guiadas por um questionario, aplicado a 100 maes que realizaram consultas de puericultura no Hospital Universitario da Universidade Federal de Santa Catarina (HU UFSC) e em outras 100 mulheres que o fizeram na Unidade de Saude do Saco Grande II (USSGII), entre janeiro e abril de 2005, totalizando uma amostra de 200 maes. Os dados foram analisados e as variaveis classificadas em categorias atraves da analise do significado e reducao das respostas. Em seguida foram organizados com o programa Epi Info 3.5 e apresentados por meio da estatistica descritiva (distribuicoes absolutas e percentuais). Resultados: O aleitamento materno foi realizado por 98% da amostra; entre as maes que amamentaram, 18,4% realizaram aleitamento materno exclusivo ate o sexto mes de vida do seu filho. O desmame foi iniciado de forma precoce por 81,6% das participantes, sendo que 46,2% dessas maes o fizeram motivadas por conceitos pessoais, 35,6% relataram algum problema relacionado a saude do bebe, 27,5% em funcao dos multiplos papeis desempenhados pela mulher-mae, 19,4% alegaram algum problema orgânico pessoal e 18,7% o realizaram por orientacao de alguem. Conclusao: A influencia cultural e familiar, o trabalho materno e problemas de saude da mae e do bebe foram determinantes para o inicio do desmame precoce.

Unintentional Injuries in Brazilian Preschool Children

Objective: To estimate the prevalence of unintentional injuries among children attending public preschools of Florianopolis (Santa Catarina, Brazil) and describe their epidemiological characteristics. Materials and Methods: This is a descriptive cross-sectional study conducted with 398 children in 2009 and data were collected through a questionnaire, filled by parents. Statistical analysis was performed, considering a confidence interval of 95%. Results: Among the 398 children included, 275 (69.1% - 95%: 66.8 to 71.4%) suffered unintentional injuries, making a total of 573 cases. The sample comprised 55.5% male children between 13 and 36 months (61.6% - 95% CI: 59.3 to 63.9%) that were affected. Child home was the place where 352 (61.4% - 95% CI: 59.0 to 63.8%) injuries occurred, 372 (64.9% - IC95%: from 59.1 to 73.7%), which were caused by falls, and 342 (59.7% - 95%:57.3 to 62.1%) were considered mild. In 223 (38.9% - 95%: 36.5% -41.3%) cases, the mother accompanied the child at the time of injury. Conclusion: The prevalence of unintentional injuries was high. In the context of prevention, combined actions among health professionals, government and civil society should be proposed based on local research on the topic. In the era of family health care performed by multidisciplinary teams, it is critical that these injuries receive adequate importance by health professionals and attention in public health policies.
