This study aims to evaluate the effect of a drug in order to avoid the appearance of side effects of human pulp fibroblasts. The groups were divided into: CTR with culture medium with fibroblasts; CL, FTL only; AA, Aloe vera with distilled water; AL, Aloe vera with distilled water and FTL; HA, calcium hydroxide P.A. With distilled water; HL, calcium hydroxide P.A. With distilled water and FTL; HAA, calcium hydroxide P.A. With Aloe vera and distilled water; HAL, calcium hydroxide P.A. With Aloe vera, distilled water and FTL. Cytotoxicity evaluation was performed with the MTT reagent at 24, 48 and 72 h, for the evaluation of genotoxicity the micronucleus test was used in 24 h. At 24 h, the CL group presented a greater media of cellular viability, and the HA showed lower mean but stimulated greater number of cell division. At 48 h, the CL group presented a higher medium of cellular viability of high genotoxicity, and the HAL showed lower mean. The AL group showed a higher percentage of surviving cells in 72 h with statistic different from the HA and HL groups (p <0.05). (P <0.001) and to the AA group (p <0.01). The AL group exhibited high genotoxicity with significant results when the CTR group (p <0.001) and the AA group (p <0.01). It is concluded that Aloe vera allowed a greater cell viability in human pulp fibroblasts in the presence of calcium hydroxide, with the increase of the genotoxicity increase in this association. Calcium hydroxide and an FTL showed higher cytotoxicity.
