The differences in composition and morphology of primary enamel have meant that higher etching times have been suggested in an attempt to favor adhesion to this substrate for a long time. However, although 15 seconds is now standard, there is no uniformity in the literature that this is sufficient to obtain adequate conditioning standards and, consequently, to allow sufficient and lasting adhesion. In pediatric dentistry, the constant search for the reduction of clinical time in order to favor the control of children's behavior and the need for evidence to guide the decision-making process justify this study, which aims to systematically review the literature for laboratory studies that evaluated the influence of different acid etching times on the bond strength of adhesive systems to enamel of primary teeth. The search for laboratory studies was performed in electronic databases (PubMed, Scopus, and ISI Web of Science) using a strategy created by combining specific (MeSH) and free terms without date or language restrictions. Two reviewers independently selected the studies following the eligibility criteria: studies that compared at least two acid etching times and evaluated the bond strength of adhesive systems to primary enamel were selected. Studies that did not present bond strength values as means and standard deviation, did not compare different etching times for the same adhesive system were excluded, as well as those that evaluated the bonding of glass ionomer cement, sealants, or orthodontic brackets. Two reviewers selected the studies, extracted the data, and assessed the risk of bias. The bond strength values were meta-analyzed using a random-effects model, with a significance level of p < 0.05. Heterogeneity (I2 ) was assessed by Cochran's Q test. Of 219 potentially eligible studies, 6 were selected for full-text analysis and 5 studies were included in the systematic review and 4 in the meta-analysis. Acid etching times longer than 15 seconds did not influence the bond strength of adhesive systems to deciduous enamel (Z=0.02; p=0.98). Heterogeneity was moderate (I2=49%; p=0.10). All studies presented a high risk of bias. Based on the results obtained, it can be concluded that the acid etching time of 15 seconds seems sufficient to promote bond strength values of adhesive systems to the enamel or primary teeth similar to longer times. As diferenças na composição e morfologia do esmalte de dentes decíduos fez com que, durante muito tempo, tempos superiores de condicionamento tenham sido sugeridos na tentativa de favorecer a adesão a esse substrato. No entanto, embora atualmente o tempo de 15 segundos seja comum, não há uniformidade na literatura de que este seja suficiente para a obtenção de padrões adequados de condicionamento e, consequentemente, permitir adesão suficiente e duradoura. Em Odontopediatria, a busca constante pela redução do tempo clínico a fim de favorecer o controle do comportamento infantil e a necessidade de evidências para guiar o processo de tomada de decisão, justificam a realização deste estudo, que tem como objetivo revisar sistematicamente a literatura para estudos laboratoriais que avaliaram a influência de diferentes tempos de condicionamento ácido do esmalte de dentes decíduos na resistência de união de sistemas adesivos. A busca por estudos laboratoriais foi realizada nas bases de dados eletrônicas (PubMed, Scopus e ISI Web of Science) a partir da estratégia criada pela combinação de termos específicos (MeSH) e livres, sem restrição de data ou idioma. Dois revisores, de forma independente selecionaram os estudos seguindo os critérios de elegibilidade de forma que, estudos que tenham comparado ao menos dois tempos de condicionamento ácido e avaliado a resistência de união de sistemas adesivos ao esmalte de dentes decíduos foram selecionados. Estudos que não apresentaram valores de resistência de união como médias e desvio-padrão, que não compararam tempos de condicionamento ácido diferentes para o mesmo sistema adesivo foram excluídos, assim como os que avaliaram a adesão de cimentos de ionômero de vidro, selantes ou braquetes ortodônticos. Dois revisores selecionaram os estudos, extraíram os dados e avaliaram o risco de viés. Os valores de resistência de união foram meta-analisados usando um modelo de efeitos aleatórios, com nível de significância de p < 0,05. A Heterogeneidade (I2) foi avaliada pelo teste Q da Cochran. De 219 estudos potencialmente elegíveis, 6 foram selecionados para análise integral do texto e 5 estudos foram incluídos na revisāo sistemática e 4 na meta-análise. Tempos de condicionamento ácido superiores a 15 segundos não influenciam a resistência de união dos sistemas adesivos ao esmalte decíduo (Z=0,02; p=0,98). A heterogeneidade foi moderada (I2=49%; p=0,10). Todos os estudos apresentaram um alto risco de viés. Com base nos resultados obtidos, pode-se concluir que o tempo de condicionamento ácido de 15 segundos parece suficiente para promover valores de resistência de união de sistemas adesivos ao esmalte de dentes decíduos similares a tempos mais longos

- Abstract
Purpose: To evaluate the longevity and factors associated with failure of primary teeth restorations placed in high caries-risk children., Methods: The sample was comprised of children treated in a University Dental Service. Patients' records were screened retrospectively to determine whether they had received restorative treatment in primary teeth presenting cavitated caries lesions. Kaplan-Meier estimator and Multivariate Cox regression analysis with shared frailty were used to assess restorations' survival and factors associated with failure, respectively., Results: 123 high caries-risk children (10.3±4 DMF-T) with 316 restorations were analyzed. The 3-year survival reached 53.4% (AFR=18.8%). Restorations placed without rubber dam (P= 0.04), over selective caries removal (P= 0.03), with calcium hydroxide liner (P< 0.01) and glass-ionomer cement (P= 0.04) presented lower survival rates. Caries-controlled patients presented significantly (P= 0.03) higher rates of restoration survival (77.7%) than caries-active patients (49.9%). The adjusted model showed that restorations placed in teeth after selective caries removal showed 3.41 times higher risk of failure compared with restorations over complete caries removal (95%CI:1.37-8.46)., Clinical Significance: Adhesive restorations placed in high-caries experience patients have limited survival rates. Some treatment-related factors may influence the performance of these restorations. A strict preventive regimen to control dental caries activity must be followed in order to increase the restoration survival., Competing Interests: The authors declared no conflict of interest. The study was funded by FAPERGS (project# 16/2551-0000471-4 PRONEX)., (Copyright©American Journal of Dentistry.)
