Vital Pulpotomy in Primary Teeth with Mineral Trioxide Aggregate (mta)

Mortal pulpotomy is the most commonly used technique in Bulgaria for treatment of pulp chronic infections in primary teeth. Data from the special literature reveal another method for pulp treatment in primary teeth – vital pulpotomy associated with good adaptive healing response. During the past several years, special attention has been paid to Mineral Trioxide Aggregate -MTA as probable alternative of formocresol. According to the current trends in dental medicine about cessation of arsenic usage and limitation on formalin – containing medicaments usage, there will be a revision of commonly used method of mortal amputation, including application of arsenic, tricresolformalin, resorcine or resorcine –formalin solutions. The aims of this study are to aprobate and popularize the technique of vital pulpotomy in primary teeth with MTA. The study was carried out with children (the children’s age was 4 – 8 years) with primary molars approximately equally affected by a carious process which had reached the dental pulp and had to be treated. The total number of studied primary teeth was 33. The methodology is “one visit” and was performed following equal clinical protocol for all teeth. The pulp stump was covered with an MTA pasteAngelus (Solucoes Odontologicas, Londrina, Brazil), prepared by mixing MTA powder with sterile saline using 3:1 powder/saline ratio. Restoration of the teeth was performed with GIC. All treated teeth were follow-up clinically and radiographically during 6 months, at 6 and 12 month after vital pulpotomy. Results: The success rate of all pulpotomized teeth with MTA was 100 % after 6 months and shows statistically insignificant decrease to 90, 9% after 12 months (p > 0, 05). The number of teeth with unsuccessful treatment is 3 or 9, 1 %. Conclusion: Vital amputation with MTA is a reliable biological method for pulp treatment of primary teeth and could be recommended for the clinical practice.
