RESUMO
The repetitive restorative cycle should be avoided, aiming at the smallest number of restorations' replacements to ensure greater tooth longevity. Antibacterial materials associated with the control of caries etiological factors can help improve restoration's durability. This review aimed to analyze the results of in vitro studies that added Dimethylaminohexadecyl methacrylate (DMAHDM), an antibacterial monomer, to restorative materials. The PubMed, SCOPUS, Web of Science, and Biblioteca Virtual em Saúde databases were screened for studies published between 2015 and 2020. After full-text reading, 24 articles were included in the final sample. DMAHDM has demonstrated antibacterial efficacy against several bacteria related to dental caries and periodontal diseases, causing a transition in the biofilm balance without inducing resistance. When DMAHDM was included in acrylic resin, the material cytotoxicity increased, and changes in mechanical properties were observed. In contrast, resin composites had their mechanical properties maintained in most studies; however, toxicity was not examined. The association between DMAHDM and 2-methacryloyloxyethyl phosphorylcholine or silver nanoparticles improved the antibacterial effect. Besides, the association with nanoparticles of amorphous calcium phosphate or nanoparticles of calcium fluoride can provide remineralization capacity. There is a lack of information on the cytotoxicity and bacteria resistance induction, and further studies are needed to address this.
RESUMO
RESUMO Introdução: Diariamente o cirurgião dentista se depara com diversos casos que exigem acurácia no diagnóstico inicial e atenção para o tratamento que irá ser proposto, uma dessas é a amelogênese imperfeita, que é uma rara alteração dentária de caráter hereditário. As características principais da amelogênese imperfeita são hipomineralização ou hipoplasia da matriz de esmalte, o que ocasiona descoloração, sensibilidade e fragilidade deste tecido, apresentando diferentes subtipos clínicos, sendo a variante hipoplásica a mais prevalente. Objetivo: Relatar dois casos de amelogênese imperfeita do tipo hipoplásica entre membros de uma mesma família, correlacionando-os. Apresentação do caso: O diagnóstico foi feito através dos exames clínico e radiográfico, além da correlação entre os achados clínicos encontrados em cada paciente e com outros familiares, sendo proposto um plano de tratamento multidisciplinar e consistente com a condição adequada. Conclusões: É importante para o cirurgião dentista estudar e conhecer essas alterações raras para poder estabelecer diagnóstico preciso. Além disso, deve-se ampliar a conduta clínica através de um planejamento individualizado e/ou familiar, tratando não apenas aspectos estéticos e funcionais, mas também psicológico e sociais(AU)

ABSTRACT Introduction: Dental surgeons are confronted every day with several cases that require accuracy in the initial diagnosis and attention to the treatment that will be proposed. One of these is amelogenesis imperfecta, a rare hereditary tooth alteration. The main features of amelogenesis imperfecta are hypomineralization or hypoplasia of the enamel matrix resulting in discoloration, sensitivity and fragility of this tissue. Of the existing clinical subtypes, the hypoplastic variant is the most prevalent. Objective: Report and correlate two cases of hypoplastic amelogenesis imperfecta in members of the same family. Case presentation: The diagnosis was based on clinical and radiographic examination, as well as analysis of the correlation between the clinical findings obtained from each patient and other relatives. The treatment plan proposed was therefore multidisciplinary and appropriately consistent with the condition. Conclusions: It is important for dental surgeons to study and be aware of these rare changes to be able to establish an accurate diagnosis. On the other hand, clinical management should be broadened through individualized and/or family planning, paying attention not only to esthetic and functional aspects, but psychological and social as well(AU)
