Análise comparativa da eficiência na obtenção de células-tronco da polpa dentária humana por meio de instrumentação manual e rotatória

Abstract

The dental pulp is considered a source of adult mesenchymal stem cells, and the interest in obtaining the dental pulp and its storage has increased substantially in recent years. Variations in the way of obtaining the pulp drastically change the final characteristic of the material removed, and the pulp is obtained manually in larger parts, more structured. In the mechanized mode, obtaining a macerated material, semi-milled. The removal of the pulp tissue via endodontic features a little known form of collecting this important tissue without the need for tooth extraction. Given the range of possibilities in technique, we observed the need to prepare a study to elucidate the changes in the collection of pulp tissues. Thirty dental pulps were collected and divided into two groups, fifteen pulps removed by mechanical instrumentation and fifteen other for manual instrumentation. After isolate stem cells from human dental pulp of permanent teeth, they were characterized as to their cell viability and plasticity: osteogenic differentiation and adipogenic. Through analysis of the results was observed that manual removal technique allowed pulp stem cell culture property derived from human dental pulp of permanent teeth in 53% of samples. Any stem cell culture was established from human dental pulp of samples obtained by rotary instrumentation.
