Avaliação da ação antimicrobiana de uma nova pasta obturadora para dentes decíduos

Abstract

This study aimed to evaluate the antimicrobial action of a new filling paste for primary teeth. After formulating the paste, the antimicrobial action was evaluated using the inhibitory halo test. Methods: Four groups of treatments were used for the evaluation: G1 – vaseline (negative control); G2- Pasta Guedes Pinto (Manipulated - Pharmacy Buenos Ayres, São Paulo, Brazil); G3- Zinc Oxide and Eugenol (OZE); G4 – Pasta Callen® (SSWhite, São Paulo, Brazil); G5 – Experimental Paste (composed of calcium hydroxide, chlorhexidine, barium sulfate, neomycin sulfate, imidazoline urea, hydroxypropylmethylcellulose and hydrochloric acid). The data obtained were submitted to statistical analysis, using specific tests for each evaluation. Results: The results showed that the highest mean inhibitory halo was observed in the Experimental Paste group, being statistically superior to all other groups tested (p<0.05). Conclusion: It was possible to conclude that the experimental paste has a significant antimicrobial action.
