The cavity systems preparation with abrasive air and burs CVD were developed to make cavities with characteristics different from the obtained by the conventional systems. Previous works demonstrate to the effectiveness of cut of both systems favoring of that way the preparation of cavities of more preservative form what the practice of a "minimally invasive Dentistry" allows. The present work must by objective present by means of the story of a clinical case the use form, characteristics of the preparations as well as the advantages and disadvantages that both systems display. Both systems were used for the removal of damages of initial decay in permanent the oclusal surfaces of first molars of a patient of 9 years of age. In molars 16 and 46 the System of Abrasive Air was used and in molars 26 and 36 the system of  CVDentus. of the made observations we can conclude that these systems were comfortable for the patient due to the characteristics of operation and efficiency of the appliances, contributing of this form for the collaboration and good behavior of the patient, as well as, to facilitate the action of the operator.
