Dycal versus Nd:YAG laser and Vitrebond for direct pulp capping in permanent teeth.
Center for Advanced Dental Education, St. Louis University, St. Louis, Missouri, USA.
PURPOSE: To determine the efficacy of laser-assisted direct pulp capping by comparing the survival rates of permanent teeth treated with Nd:YAG laser and Vitrebond (3M Corporation, St. Paul, MN) direct pulp caps to permanent teeth treated with the traditional calcium hydroxide direct pulp cap over intervals of up to 54 months. SUMMARY BACKGROUND DATA: While there are case reports and evaluations of various laser techniques in the literature, statistical studies comparing the success of laser-assisted applications to traditional techniques are needed. This is a retrospective investigation of one such laser assisted application. METHODS: A retrospective chart review of all active and inactive patients resulted in the identification of 83 patients who received direct pulp caps in a total of 93 permanent teeth; 29 with calcium hydroxide and 64 with Nd:YAG laser and Vitrebond. RESULTS: Life table analysis of the data of this retrospective study demonstrated that the teeth treated with the laser and Vitrebond direct pulp cap showed significantly greater survival rates than those treated with Dycal direct pulp cap over intervals of nine to 54 months postoperatively. The cumulative proportion of teeth surviving postoperatively for the Dycal (L.D. Caulk Corporation, Milford, CT) direct pulp cap was 89.7% at 1 month declining to 79.4% at 3 months and 76% at 6 months and then continued to decline in the final two intervals finishing after 54 months at 43.6%. For the laser and Vitrebond direct pulp cap the cumulative proportion surviving stood at 98.4% after 1 month, declining to 93.8% at 3 months and 90.3% after 6 months but then held steady in the final 2 intervals finishing at 90.3% after 54 months. CONCLUSION: The laser and Vitrebond direct pulp cap produces a significantly more predictable pulpal response after the first 6 months than the Dycal direct pulp cap. The survival rate of teeth treated with the laser and Vitrebond direct pulp cap is significantly greater than those treated with the Dycal direct pulp cap over intervals of 9 to 54 months. Direct pulp capping is a worthwhile procedure that should be performed when indicated, especially in light of the 90.3% survival rate achieved with the laser and Vitrebond direct pulp cap at 54 months.
