Aderência de bactérias em ligaduras ortodônticas e desinfecção com uso de colutórios

Uma higiene bucal deficiente favorece o acumulo de placa bacteriana e o inicio de inflamacao gengival. O uso de aparelhos ortodonticos tem um grande impacto sobre a microbiota bucal porque fornece sitios extras de adesao bacteriana. O uso de substâncias quimicas vem sendo empregado com o objetivo de inibir a formacao de biofilme dental, crescimento bacteriano e a adesao de bacterias as superficies. O presente estudo comparou a aderencia de bacterias em ligaduras da marca Morelliri e OrthoSourceri e a potencial desinfeccao pelos colutorios: Plax Iceri, Listerine Vanilla Mintri, Malvatricinri, Periogardri e Solucao de Clorexidina 0,12% + Oleos essenciais (produto manipulado, Fleming Farmacia de Manipulacao). As ligaduras foram encubadas em suspensao multibacteriana e imersas nos agentes quimicos. Apos a semeadura e contagem de UFC/mL, os resultados foram avaliados estatisticamente. Nao houve diferenca significativa na aderencia de bacterias ao compararmos as duas marcas (p>0.05) e houve grande eficacia na desinfeccao com o uso dos colutorios Periogardri e Listerine Vanilla Mintri (p Deficient oral hygiene favors biofilm formation and outset of gingival inflammation. The use of orthodontic appliances has an important impact on the oral microbiota once it provides additional sites of bacterial adhesion. Chemicals have been employed in order to inhibit the formation of biofilm, bacterial growth, and adhesion of bacteria to surfaces. This study compared the adherence of bacteria on MorelliO and OrthoSourceO elastic ligatures and potential disinfection by mouthwashes: Plax IceO, Listerine Vanilla MintO, MalvatricinO, PeriogardO and chlorhexidine solution 0.12% + essential oils (Fleming Farmacia de Manipulacao, Ponta Grossa - PR). Ligatures were incubated in multibacterial suspension and soaked in the chemicals. After platting on agar and obtaining the number of cfu/mL, results were evaluated statistically. No significant difference in bacterial adherence was observed when compared the two brands (p>0.05) and disinfection with the mouthwashes was very effective, mainly with PeriogardO and Listerine Vanilla MintO (p
