RESUMO
OBJECTIVES: This review evaluated the effects of the acidic composition of self-etch (SE) adhesives at the long-term bond strengths to dentin and enamel. DATA: The review followed the PRISMA Extension Statement for network meta-analysis. Studies were identified by a systematic search in PubMed, Web of Science, and Scopus databases. STUDY SELECTION: The inclusion criteria were in vitro studies that evaluated bond strength data of samples analyzed at both immediate and long-term (after aging simulation) periods and that were bonded to sound dentin/enamel using SE adhesives, with at least one group of adhesives being based on 10-MDP (10-methacryloyloxy-decyl-dihydrogen-phosphate; control) and the other group being comprised of alternative acidic monomers. Statistical analyses were conducted using two methods: standard pairwise meta-analysis (SPMA) and Bayesian network meta-analysis (NMA). Heterogeneity was assessed by using the Cochran Q test and I2 statistics. RESULTS: From 5220 studies identified, 87 met the eligibility criteria and 83 were meta-analyzed. Seventeen adhesives were based on 10-MDP and 44 systems were based on alternative acids. The resin-dentin/enamel bonds were predominantly reduced after aging (â¼84% of cases). From the SPMA findings, the following acidic compositions showed lower bond strength values (effect size: mean difference [MD] with 95% confidence interval [95% CI]) than 10-MDP: 4-META (MD -4.99, 95% CI: -7.21, -2.78; p<0.001); sulfonic acids (MD -9.59, 95% CI -12.19, -6.98; p<0.001); unspecified phosphate esters (MD -8.89, 95% CI -17.50, -0.28; p = 0.04); or mixed acids (MD -11.0, 95% CI -13.62, -8.38; p<0.001). The dental bonds were benefited from the presence of 10-MDP upon longer aging (>6 months). From the NMA probabilistic findings, adhesives based on 10-MDP and phosphonic acids ranked as having the best and the worst bonding potential to dentin, respectively. More than one composition (phosphonic acids and mixed acids) ranked similarly to 10-MDP in enamel. The studies scored as having moderate risk of bias (58.6%), followed by low (39.1%) and high (2.3%) risk of bias. CONCLUSION: 10-MDP is an outstanding acidic monomer that contributes to higher bonds to dentin at the long-term. In enamel, there is no evidence that one acidic composition prevails over the other. CLINICAL SIGNIFICANCE: The acidic composition of SE adhesives affects the resistance of dental bonds after simulated aging, with 10-MDP playing a significant role in the adhesion to dentin but not to the enamel.

A articulação temporomandibular (ATM) possibilita a mastigação, deglutição e a fonética, faz parte do sistema estomatognático, e é capaz de múltiplos movimentos. A DTM (disfunção temporomandibular) representa certas condições musculares e articulares na região crânio orofacial que podem causar problemas nos músculos da mastigação e na ATM e suas estruturas associadas, sendo a cefaleia e a dor orofacial alguns dos principais sintomas relatados pelos pacientes. Objetivo: analisar a relação da DTM à dor orofacial e cefaleia através de uma revisão narrativa. Métodos: para a realização deste estudo, foram feitas buscas nas bases de dados Scielo e Pubmed, utilizando as palavras chave: Dor Orofacial, Disfunção Temporomandibular, Articulação Temporomandibular, Dor de Cabeça e Cefaleia. Conclusão: a partir dos artigos analisados na presente revisão foi possível concluir que existe relação entre dor na região orofacial e cefaleia com a DTM, porém ainda não é claro o mecanismo dessa correlação, sendo necessários mais estudos para elucidar esse quadro clínico(AU)
The temporomandibular joint (TMJ) enables mastication, swallowing and phonetics, is part of the stomatognathic system, and is capable of multiple movements. DTM (temporomandibular dysfunction) represents certain muscular and articular conditions in the orofacial cranial region that can cause problems in the masticatory muscles and on TMJ and associated structures, with headache and orofacial two of the main symptoms pointed by patients. Objective: to analyze the relationship of TMD to orofacial pain and headache through a narrative review. Method: for this study, research was done in the databases Scielo and Pubmed, using the key words: Orofacial Pain, Temporomandibular Dysfunction, Temporomandibular Joint, Headache and Headache. Conclusion: from the articles analyzed in the present review it was possible to conclude that there is a relationship between orofacial pain and headache with TMD, but the mechanism of this correlation is not yet clear, and further studies are needed to elucidate this clinical case(AU)
