RESUMO
ABSTRACT Objective: To evaluate the knowledge of orthodontic professionals regarding the prescription of dentifrices and antiseptics during orthodontic treatment. Methods: An observational and descriptive exploratory study of national scope was conducted with 440 Brazilian orthodontists, based on previous sample calculations, to evaluate the clinical practice of orthodontists in prescribing dentifrices and antiseptics. Self-managed electronic questionnaires were sent to orthodontic professionals. The data were analyzed by means of absolute and relative frequency distribution tables. Results: It was verified that the most indicated mouthwash (39.8%) was Colgate Periogard® and 421 of the participants (95.7%) know its active ingredient (chlorhexidine digluconate). Besides Colgate Periogard® antiseptic, the participants were also questioned about which active ingredient present on the following antiseptics, whose assertive answers were in the following order of %, Cepacol® (Sanofi-Aventis®) with 60.7%, Colgate Plax® (Colgate®) with 54.5% and Listerine® (Jhonson&Jhonson®) with 51.6%. As for the chlorhexidine therapeutic regime, 63.9% have stated assertively its use, being this one of 2 times a day during 7 to 10 days. The most indicated tooth was Colgate Total 12®, and 60.18% of these individuals correctly indicated its active compound. Conclusion: According to the methodology employed, it could be concluded that orthodontic professionals know and prescribe methods of chemical control to patients during orthodontic treatment and most identify the active chemical compounds present in antiseptic and tooth formulas.
RESUMO Objetivo: Avaliar o conhecimento dos profissionais da ortodontia quanto à prescrição de dentifrícios e antissépticos durante o tratamento ortodôntico. Métodos: Foi realizado um estudo observacional e descritivo exploratório de abrangência nacional com 440 ortodontistas brasileiros, baseado em cálculo amostral prévio, para avaliação da prática clínica dos ortodontistas na prescrição de dentifrícios e antissépticos. Questionários eletrônicos auto administrados foram enviados aos profissionais da Ortodontia. Os dados foram analisados por meio de tabelas de distribuição de frequência absolutas e relativas. Resultados: Verificou-se que o antisséptico bucal mais indicado (39,8%) foi o Colgate Periogard® (Colgate®) e 421 dos participantes (95,7%) conhecem o seu ingrediente ativo (digluconato de clorexidina). Além do antisséptico Colgate Periogard®, os participantes também foram questionados sobre qual o ingrediente ativo presente nos seguintes antissépticos, cujas respostas assertivas estavam na seguinte ordem %, Cepacol® (Sanofi-Aventis®) com 60,7%, Colgate Plax® (Colgate®) com 54,5% e Listerine® (Jhonson&Jhonson®) com 51,6%. Quanto ao regime terapêutico da clorexidina 63,9% indicaram assertivamente sua utilização sendo a mesma de 2 vezes ao dia durante 7 a 10 dias. O dentifrício mais indicado foi o Colgate Total 12®, sendo que 60,18% desses indivíduos indicaram corretamente seu composto ativo. Conclusão: De acordo com a metodologia empregada, pôde-se concluir que os profissionais da ortodontia conhecem e prescrevem métodos de controle químico aos pacientes durante o tratamento ortodôntico e a maioria identifica os compostos químicos ativos presentes nas fórmulas de antissépticos e dentifrícios.
RESUMO
Alternanthera brasiliana (L.) Kuntze is recognized for its healing properties; however, its therapeutic effects remain unclear. Therefore, our study aimed to elucidate the wound healing activities of A. brasiliana using in vitro and in vivo assays. In vitro assays were used to evaluate the antibacterial, anti-inflammatory, and antioxidant effects of A. brasiliana extract. For the in vivo study, two dorsal excisions were established in Wistar rats using a punch (1.5 cm in diameter), which were topically treated daily with 2% carbopol gel (Ctrl group) or 20% hydroalcoholic plant extract with 2% carbopol gel (A. brasiliana-Ab group). After the 2nd, 7th, 14th, and 21st days, inflammation, oxidative damage, antioxidants, angiogenesis, tissue formation, and re-epithelialization were evaluated. In vitro, Ab reduced nitric oxide, anion superoxide, and pro-inflammatory cytokine production. In vivo, Ab presented lower levels of inflammatory infiltrate, although increased levels of IL-1ß and TGF-ß1 were observed. The plant extract controlled oxidative damage by antioxidants, which favored angiogenesis, collagenesis, and wound re-epithelialization. Thus, the topical application of the hydroalcoholic extract of 20% A. brasiliana was distinguished by its important anti-inflammatory and antioxidant activities both in vivo and in vitro. The plant extract also stimulated angiogenesis and tissue formation, accelerating total re-epithelization, which is promising for wound healing.
