Vital pulpotomy in primary teeth with mineral trioxide aggregate (MTA)

Abstract

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 paste-Angelus (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.Despite the advance in knowledge about the onset, nature, progression, prevention opportunities and nonoperative treatment of carious process, the disease and its complication are still main clinical problem (23). Extensive dental decay in the primary dentition, that reaches and progresses to the dental pulp, remains a serious problem in

Comparative evaluation of three different materials: mineral trioxide aggregate, triple antibiotic paste, and abscess remedy on apical development of vital young permanent teeth

“…[ 6 ] In the present study, 60 immature teeth were selected in children aged between 6 and 14 years according to the clinical and radiographic criteria based on previous studies. [ 9 10 11 12 ]…”

“…Isolation of teeth to prevent contamination plays a key role in the success of any pulp treatment;[ 9 ] hence, all cases were performed after isolation with rubber dam. As pulpotomy is indicated in vital teeth vitality test was done using electric pulp tester, and test cavity preparation was made on unanesthetized tooth.…”

Coronal Pulpotomy Technique Analysis as an Alternative to Pulpectomy for Preserving the Tooth Vitality, in the Context of Tissue Regeneration: A Correlated Clinical Study across 4 Adult Permanent Molars

“…The success rates of these procedures performed on primary teeth and on immature permanent teeth with open apices have been well documented. A clinical study was conducted by Kabaktchieva and Gateva on 4–8-year-old children in 33 primary molars, affected by the carious process, which revealed a 100% success rate of MTA pulpotomy after 6 months [ 13 ]. Another clinical investigation of similar nature was conducted by Nyerere et al in 2006 in 180 patients over 15 years of age, with a chief complaint of pain associated with acute pulpitis.…”

Assessing Clinical and Radiographic Evidence of Failure Following Pulp Therapy in Primary Anterior and Posterior Teeth Among Patients Less Than Six Years Old

“…Statistical analysis revealed no statistical significant difference (P =0.410). Table (6) shows the association between radiographic and clinical failure scores using the x 2 & Fisher's exact tests.…”

“…Absence of sensitivity on percussion, swelling or fistula or pathological tooth mobility dictates clinical criteria for successful pulp therapy 5 . On the other hand, radiographic criteria for successful pulp therapy include; absence of furcational radiolucency or external/internal root resorption or other pathological changes that might endanger the developing permanent successor 6 .…”
