Root canal treatment in necrotic primary molars.
Fifty-three patients (27 boys and 26 girls) with necrotic primary teeth received root canal treatments with a paste consisting of KRI-1 paste and pure calcium hydroxide powder with one drop of formocresol. All cases were followed clinically, radiographically and some histologically at 6, 12 and 17 to 24 months postoperatively. All cases were clinically and radiographically successful.
