Abstract
A histological study to evaluate human pulpal responses following caries removal treatment by the Caridex caries removal system was conducted utilizing fifteen human teeth. The teeth employed in this investigation were previously scheduled to be extracted and possessed a carious lesion involving only enamel and dentin. Vitality of the dental pulp was confirmed through a series of diagnostic tests. Following caries removal by the Caridex system, a temporary zinc oxide-eugenol (ZOE) restoration was placed in the cavity preparation. The teeth were extracted either seven days post-operatively or thirty days post-operatively, and then histologically prepared and examined. Histological evaluation of the specimens in the seven day post-operative group revealed three specimens which demonstrated a possible hyperemic response; two specimens displayed a generalized inflammatory response indicative of a carious pulp exposure, although no exposures were observed; one specimen revealed a localized inflammatory response; and two specimens displayed normal pulp tissue. Examination of specimens in the thirty day post-operative group found three specimens which demonstrated a possible hyperemic response, and four specimens which displayed normal pulp tissue. No generalized or localized inflammatory response was noted. Analysis of the histologic sections also revealed that six of the fifteen specimens showed evidence of dental caries remaining on the surface of the cavity preparation and extending into dentinal tubules. Additionally, caries removal by the Caridex system was noted to be a slow and lengthy process. Actual caries removal time ranged from nine minutes to 22 minutes, with an average caries removal treatment phase of 15.5 minutes. Based on the evaluation of the teeth utilized in this study, the following conclusions may be drawn: 1. No significant inflammatory response was observed in carious teeth following treatment by the Caridex caries removal system in either the seven day or thirty day post-operative groups which could be attributable to the Caridex system. 2. Dental caries were found to remain on the cavity preparation surface following diligent caries removal treatment utilizing the Caridex system in 40% of the teeth studied. 3. Exceptionally long caries removal treatment times were necessary in order to obtain clinically caries-free cavity preparations. However, histologically, caries were demonstrated to still be evident in six of the fifteen specimens studied. 4. The Caridex caries removal system seems to be a good marketing tool for dentists however, with incomplete caries removal, protracted treatment times, the relatively high cost of the system, and the need for rotary instruments after caries removal in order to refine the cavity preparation and place retention, the Caridex system does not appear to be a practical addition to the dental armamentarium of caries removal techniques as it currently exists.
