ABSTRACT

OBJECTIVES: The antiplaque and antigingivitis effect of Lippia Sidoides (LS) was evaluated in this in vivo investigation. MATERIAL AND METHODS: Twenty-three subjects participated in a cross-over, double-blind clinical study, using 21-day partial-mouth experimental model of gingivitis. A toothshield was constructed for each volunteer, avoiding the brushing of the 4 experimental posterior teeth in the lower left quadrant. The subjects were randomly assigned initially to use either the placebo gel (control group) or the test gel, containing 10 percent LS (test group). RESULTS: The clinical results showed statistically significant differences for plaque index (PLI) (p<0.01) between days 0 and 21 in both groups, however only the control group showed statistically significant difference (p<0.01) for the bleeding (IB) and gingival (GI) index within the experimental period of 21 days. On day 21, the test group presented significantly better results than the control group with regard to the GI (p<0.05). CONCLUSIONS: The test gel containing 10 percent LS was effective in the control of gingivitis.

ABSTRACT

O objetivo deste estudo foi avaliar o efeito de diferentes concentrações do extrato hidroalcoólico de alecrim-pimenta sobre amostras microbiológicas, comparando-o com uma solução de digluconato de clorexidina a O,12%. Estas amostras foram obtidas de um biofilme supragengival com uma semana de colonização, colocadas em meio de cultura BHI (Brain Heart Infusion) e replicadas em placas de ágar ûsangue contendo discos imersos em diferentes concentrações do extrato de alecrim-pimenta (0,1%, 0,5 %, 1%, 2%, 5% e 10%), em solução de clorexidina a O,12%, em solução salina e em álcool absoluto. As concentrações a partir de 2% demonstraram halo de inibição semelhante à dorexidina, enquanto que a solução alcoólica e de soro fisiológico não apresentaram efeito inibitório no crescimento bacteriano. Portanto, o extrato hidroalcoólico do óleo essencial de alecrim-pimenta nas concentrações de 2%, 5% e 10% exerceu efeito inibitório "invitro" sobre amostras microbiológicas de biofilme supragengival de forma similar à solução de clorexidina a 0,12%.
