Abstract
- The leakage associated with restorative materials placed within the pulp chamber of maxillary and mandibular molars was studied <em>in vitro</em>. The root canals and pulp chambers of 69 extracted teeth were prepared chemomechanically and sealed with gutta-percha and Tubliseal using cold lateral condensation. The teeth were divided into five groups. Gutta-percha was removed from the pulp chambers of three of the groups of 15 teeth and filled with one of three materials, a glass ionomer cement, a cement or an amalgam. The gutta-percha was removed from the pulp chamber in the fourth group of nine teeth, which were left unfilled. The gutta-percha in the pulp chambers of the fifth group of teeth was left intact. The teeth were suspended in Indian ink, thermocyded for 24 hours and stored for a further 48 hours at 37°C. They were then demineralized and cleared and the degree of coronal leakage was assessed. Those teeth with no filling in the pulp chamber showed extensive leakage. The gutta-percha-filled group demonstrated rearer leakage than did the groups in which other restorative materials had been employed (<em>P</em><0.01). No significant differences in leakage occurred between the other groups (<em>P</em>0.05). It is recommended that the pulp chamber of molars should be restored with a filling material following root canal treatment. [ABSTRACT FROM AUTHOR]
