Apexification is a therapeutic technique applied to generate calcified apical barrier in root with open apex. This technic promotes the formation of an apical bulkhead in order to foster an acceptable environment for root canal filling. Many materials have been developed with the purpose of promoting the formation of an apical barrier by the deposition of mineral tissue. Thereby, the purpose of this study was to investigate clinical studies through a systematic review, evaluating the efficiency of calcium hydroxide (CH) and mineral trioxide aggregate (MTA) in the treatment of teeth with incomplete root formation. The selected databases were PubMed, Web of Science, SCOPUS by the keyword “apexification”. On the BIREME database the research happened by the keywords “apexification” and “apexificação”. As research criteria, we delimited researches from last ten years (1992 to July 2012). Also, the review was conducted by the inclusion criteria of clinical studies evaluating comparatively the use of HCA and MTA in therapy of incomplete root formation teeth on humans. By the researched keywords a total of 2292 studies were found. Nevertheless, only three studies precisely match within the inclusion criteria. The results demonstrate that equally MTA and calcium hydroxide are suitable for the apexification technique on immature permanent teeth. Notwithstanding, scientific evidence were hamper by the lack of controlled clinical studies. These results suggest vast opportunity for continuous approach on both materials.
