Forty-three endodontic specialists recorded the occurrence of all adverse treatment events in 3308 consecutive conventional endodontic cases. Statistical analysis confirmed that retreatment cases and mid-treatment referral cases have a greater incidence of adverse treatment events. Since the doctrine of informed consent requires that the doctor inform the patient of reasonably foreseeable consequences of treatment, it is therefore important that the endodontist be cognizant of such events and decide what information is appropriate for disclosure. Since jurisdictional differences exist in the interpretation of what constitutes sufficient informed consent, it is important that local groups investigate the statutes in their state and construct reasonable informed consent documents.

Sealing quality of polycarboxylate cements when compared to amalgam as retrofilling material.

Four hundred roots were uniformly prepared for retrofilling. One hundred of these were retrofilled with amalgam and served as controls for the study. The polycarboxylate cements--Durelon, PCA, and Poly C--were each used as retro-filling material for 100 roots. After immersion in 2 per cent aqueous methylene blue for 7 days, the roots were sectioned in 1 to 2 mm. increments to determine the depth of dye penetration. The depth of dye penetration was used as a measure of their sealing effectiveness. The groups were compared statistically by means of a t test. All cements were significantly different from amalgam. All cements performed inferiorly to amalgam, an already accepted retrofilling material.
