Teething symptoms in the first year of life and associated factors: a cohort study.

OBJECTIVE: To investigate the occurrence and management of teething symptoms during the first year of life and associated factors. STUDY DESIGN: 500 children were recruited at birth. Research assessments including structured interviews, anthropometric measurements and dental examination were carried out after birth, at 6 months and at one-year of age. The primary outcome of this study was defined as the occurrence of one or more teething symptoms within the first year of life, as reported by the mother. RESULTS: Teething symptoms were reported in 73% of the children analyzed (273/375). The symptoms most frequently reported were irritability (40.5%), fever (38.9%), diarrhoea (36.0%) and itching (33.6%). Dentists had little influence on the management of symptoms and self-medication to relieve them was a common practice. The risk of reporting teething symptoms was higher for children from nuclear families (p = 0.040) and for children from families with higher income (p = 0.040). CONCLUSIONS: Teething symptoms were highly reported in this population. Pediatric dentists should be accessible and provide adequate orientation when symptoms can be managed at home or immediate referral to health services when more serious diseases are suspected.

Mensuração da tensão superficial de diferentes substâncias utilizadas na terapia endodôntica / Measurement the surface tension’s substances used in endodontic therapy

A proposta deste estudo foi mensurar a tensão superficial de diferentes substâncias utilizadas na terapia endodôntica através do método da ascensão capilar. Para a realização deste experimento, foi utilizado um tubo capilar de vidro com diâmetro interno de 0,5 mm e20 cm de comprimento que propiciava a ascensão dos líquidos após imersão em um volume fixo das soluções testes. Posteriormente, aspiraram-se tais líquidos, aguardando sua estabilização no interior do capilar, sendo então determinada a coluna líquida do capilar. Como resultado obtiveram-se as seguintes tensões superficiais, em ordem decrescente: NaOCl 1%(60,7 dinas/cm), tricresol formalina (27,2 dinas/cm), PMCC (25,5 dinas/cm). Também severificou a hipótese de reduzir a tensão superficial em soluções de EDTA, quando da adição de doses crescentes de detergente, onde se obteve os seguintes resultados: EDTA 17% +0,1% de tergentol (45,60 dinas/cm), EDTA 17% + 0,5% de tergentol (45,69 dinas/cm), EDTA17% + 1% de tergentol (28,34 dinas/cm), EDTA 17% + 5% de tergentol (24,58 dinas/cm),EDTA 17% + 10% de tergentol (17,68 dinas/cm).

This research purpose measure the surface tension’s substances used in endodontic therapy by means of creeping. The authors used a tube glass capillary with inside diameter 0,5 millimeter and length 20 centimeter. The tube propitiate the liquid’s ascension. Liquids were aspirated and after stabilization into the tube glass capillary was measured the capilar’s liquid column. The surface tension’s result were: sodium hypochlorite 1% (60,7 dynes/c), tricresol formalin(27,2 dynes/c), PMCC (25,5 dynes/c). Besides the authors testify the hypothesis the surface tension’s reduction of EDTA solutions when increased cleanser’s crescent doses. The findingswere: EDTA 17%+0,1% tergentol (45,60 dynes/c); EDTA 17%+0,5% tergentol (45,69 dynes/c); EDTA 17%+1% tergentol (28,34 dynes/c); EDTA 17%+5% tergentol (24,58% dynes/c) eEDTA 17%+10% tergentol (17,68 dynes/c).

Evaluation of the methodologies used in clinical trials and effectiveness of chemo-mechanical caries removal with CarisolvTM

This investigation aims to discuss the methodologies applied in clinical trials published about CarisolvTM, in order to assess the best scientific evidence concerning chemo-mechanical caries removal. Papers concerning the use of CarisolvTM were sought using a search strategy. The titles and abstracts of all the reports identified through the search were analyzed by a single reviewer. The inclusion criterion involved: clinical trials having CarisolvTM in one of the study groups. Then, those that fulfilled the inclusion criterion underwent methodology assessment and data extraction. Only 12 papers met the inclusion criterion. It was observed that none of these studies complied with all the evaluated research methodological principles required in order to have power of evidence generation. CarisolvTM proved to be effective in caries removal. Appointment mean time was greater, but the perceived time was shorter than that using conventional techniques due to patients' perception of more comfort and a reduction of anesthesia needs. There were no adverse effect in long-term assessments. In studies with microbiological evaluation of the remaining dentine, it was observed that both the conventional and chemo-mechanical methods produced statistically significant reduction on counts of viable microorganisms.

Esta investigação objetiva discutir as metodologias aplicadas em ensaios clínicos publicados sobre Carisolv®, para verificar a melhor evidência científica concernente à remoção químico-mecânica de tecido cariado. Artigos referentes ao uso de Carisolv® foram procurados utilizando-se uma estratégia de busca. Os títulos e resumos de todos os estudos identificados pela procura foram analisados por um único revisor. O critério de inclusão envolveu: ensaios clínicos contendo o sistema Carisolv® em um dos grupos de estudo. Os estudos que preencheram o critério de inclusão foram submetidos à avaliação de metodologia e extração de dados. Somente 12 artigos preencheram o critério para inclusão. Foi verificado que nenhum desses estudos obedeceu a todos os princípios metodológicos considerados necessários para que uma pesquisa tenha poder de geração de evidências. O Carisolv® demonstrou ser eficaz na remoção de tecido cariado. O tempo de consulta foi maior, mas o tempo percebido foi inferior em comparação ao tempo das técnicas convencionais devido à percepção dos pacientes de mais conforto e de redução da necessidade de anestesia. Não houve efeito adverso em avaliações a longo prazo. Em estudos com avaliação microbiológica da dentina remanescente foi verificado que ambos os métodos convencional e químico-mecânico produziram redução significativa na contagem de microrganismos viáveis.
