El objetivo de este estudio, paralelo, doble ciego clínico, fue evaluar el efecto de un gel conteniendo extracto de aruera en 10% en la reducción del acúmulo de placa supragingival y gingivitis. Los sujetos de la investigación fueron distribuidos en grupo prueba (n=15 gel aruera) y grupo control (n=15 gel placebo). La cantidad de placa fue evaluada por medio del índice de placa de Turesky-Gilmore-Glickman (IPL), el grado de gingivitis por el índice gingival de Löe & Silness (IG) y el grado de inflamación por el índice de sangramiento gingival de Ainamo & Bay (ISG). Los participantes fueron orientados a cepillar los dientes con el gel tres veces al día, por treinta días. Hubo diferencia significativa para los tres índices evaluados en los grupos prueba y control de forma similar pasado los treinta dias. El gel de aruera en 10% asociado al control mecánico de placa no demostró efecto agregado en la reducción de placa bacteriana supragingival ni en gingivitis

The aim of this randomized, parallel, double-blind clinical trial was to evaluate the effect of a gel containing 10% of myracrodruon urundeuva extract on the reduction of plaque and gingivitis. Subjects were randomly allocated into either the test group (n=15, test gel) or the control group (n=11, placebo gel). Plaque levels were measured using the Turesky-Gilmore-Glickman index (PLI) and gingivitis was evaluated through Gingival index of Löe & Silness (GI) and gingival bleeding index of Ainamo & Bay (GBI). Subjects were asked to brush their teeth with the gel, three times a day, for thirty days. There was a significant difference in all indexes for the both groups in a similar manner after the end of the trial. In conclusion, the gel containing 10% of myracrodruon urundeuva did not showed a additional effect on reduction of plaque and gingivitis

The effect of Aloe vera on the reduction of plaque and gingivitis was evaluated in a randomized, parallel and double-blind clinical trial. Subjects were randomly allocated to the test group (n=15) - dentifrice containing Aloe vera - or the control group (n=15) - fluoridated dentifrice. Plaque index (PI) and gingival bleeding index (GBI) were assessed at days 0 and 30. Subjects were asked to brush their teeth with the control or test dentifrice, three times a day, during a 30-day period. There was a significant reduction on plaque and gingivitis in both groups, but no statistically significant difference was observed among them (p>0.01). The dentifrice containing Aloe vera did not show any additional effect on plaque and gingivitis control compared to the fluoridated dentifrice.
