Direct pulp capping successful treatment can be seen through evaluation of clinical, histological and radiographic. Clinical evaluation aims to determine the condition of the pulp that has been taken care through objective and subjective examination. The use of hard setting calcium hydroxide as a material direct pulp capping at the Dental Hospital UMY in the high category. The purpose of this study was to determine the clinical evaluation of success direct pulp capping with calcium hydroxide material type of hard setting at the Dental Hospital UMY. Methods clinical evaluation direct pulp capping at the Dental Hospital UMY using secondary data, the medical records of patients who had taken care direct pulp capping during the years 2011-2015 at the Dental Hospital UMY. The results of the clinical evaluation direct pulp capping at the Dental Hospital UMY found that success with a good category as 89.40%, enough category of 5.30% and 5.30% less category. Differences in age, sex there is no consideratrion means in success.
