This study aimed to determine how the richness and composition of ant species behaves with changes in the recovery process of a gully erosion. The study area has 0.9 hectares subdivided into three sections called sector: A, B and C. For the definition of the sectors, erosive and natural restoring were taken as the base level of activity. Four transects were laid systematically throughout the area and surrounding compound with forest and grassland. Each transect had three pitfall trap ten meters apart from each other, with catches of ants were held in rainy and dry seasons. Analysis of variance was applied to compare the number of ant species per plot captured and Scott-Knott test 5% for comparison of means. To verify the similarity of species between environments it was performed an analysis of similarity (ANOSIM) and ordering of environments a Nonmetric Multidimensional Scaling (NMDS). We captured 74 species of ants inside and around the gully erosion. The more degraded environment and initial stage of regeneration, showed greater richness of ant species. The composition of ant species was different between the recovery environments and around. The parameters of ant communities analyzed, richness and composition species were influenced by the regeneration of the area, indicating that ants can be used as bioindicators of gullies recovery.

The study of the dental pulp can be extended from factors related to its aggression to those related to new concepts of regeneration. The purpose of this compilation of studies is to present the evolution of a research subject from damage to repair. Innitially, studies will demonstrate the ability of dental procedures to generate heat and consequently affect the dental pulp. In sequence, studies will also present some effects of different pulp capping materials on dental pulp cells, related to the cytotoxicity of these materials and inflammatory potential. Finally, as the subject is emmerging and gaining importance in the literature, this compilation will present data from recent studies on the role of dental pulp progenitor cells in the regeneration and repair of dental pulp, as well as an alternative for a scaffold that could be used for clinical translation of research in the field. In summary, dentists must be aware of these different aspects and that the knowledge on factors and mechanisms involved in the aggression of the dental pulp can also serve as basis for understanding aspects for regeneration.
