Endodontic treatment depends on several aspects such as pulp vitality among others. In case of biopulpectomies which must be delayed for several reasons, there is no a general agreement related to the most appropriate type of interappointment intracanal dressing. Among them, one of the most accepted are Calcium Hydroxide pastes owing to their antimicrobial and tissular repair properties. However, toxicity of this paste over periapical tissues have been reported in experimental investigations. In this research Aloe vera gel was proposed as vehicle of Calcium Hydroxide paste because of both its physical-chemical characteristics, which may diminish the toxicity of this paste, and its biological properties, which might improve the tisular response to Calcium Hydroxide paste. The purpose of this research was to determine whether there was difference in the diffusion of hydroxyl and calcium ions between Calcium Hydroxide intracanal dressing using Aloe vera gel as vehicle from other convencionals. Three calcium hydroxide (CH) pastes were prepared: Paste A, CH with Aloe vera gel; Paste B, CH with glycerine; and Paste C, CH with destilated water. The elected experimental design was an in vitro model using capilar glass tubes containing calcium hydroxide pastes, being 10 tubes for each paste. Those tubes were sumerged into individual bottles for each tube, containing 50 ml of deionizated water as analysis medium. Experimental time was 14 days, performing measurements at 3, 24, 72, 168 and 336 hours. Results were analysed using statical tests such as ANOVA One Way, Tukey post hoc and t-test (p<0.01). Ionic diffusion of pastes A, B and C varied during experimental time, finding a tendency to stabilise after reaching a diffusion peak into the analysis medium. Hydroxyl ion diffusion of Paste A was minor than that of Paste B at 3 and 24 hours; whereas at 72, 168 and 336 hours there was no statistically significant difference between them. Hydroxyl ion diffusion of Paste A was minor than that of Paste C from 24 to 336 hours. There was no statistically significant difference of calcium ion diffusion between Pastes A and B at 3, 72 and 168 hours. Although Paste A had more diffusion than Paste B at 24 hours, but it had minor diffusion at 336 hours. There was no statistically significant difference of calcium ion diffusion between Pastes A and C at 3 hours. Calcium ion diffusion of Paste A was greater than that of Paste C at 24 and 72 hours, while it was minor at 168 and 336 hours. Analysing the conventional vehicles, Paste B showed almost same diffusional characteristics of Paste A versus Paste C. Calcium and hydroxyl ions diffusion of Calcium Hydroxide paste with Aloe vera gel (Paste A) was different from those of Calcium Hydroxide pastes using conventional vehicles (Pastes B and C). Aloe vera gel influences on calcium hydroxide paste diffusion by diminishing hydroxyl ions diffusion and modulating calcium ions diffusion.
