With the aim to identify dormant or extinct comet nuclei among the Hildas, the orbital parameters of more than 4000 of these asteroids were analyzed to find outliers in the quasi-hilda region. Around 1000 objects were found in this zone using the orbital excitation parameter and the planes of the Lagrangian elements as tools to discriminate between Hildas and quasi-hildas objects. Several of these outliers were integrated backward in time to know their recent dynamical evolution and to better find comet candidates among them. Preliminary results of this research are shown in this work.
