Endodontic retreatment.
Pak Oral Dental J Jan ;34(4):722-5.

To salvage a failed root treated tooth, retreatment is often warranted. Although some retreatment guidelines are there but on many areas there is no consensus on retreatment protocols and procedures. A study was planned to assess the endodontic retreatment preferences and decision making among practicing dentists of Karachi. This study also compared the retreatment preferences of dentists on the basis of their clinical experience.A questionnaire was distributed to participants. Information was obtained on retreatment cases, use of medicaments, solvents and antibiotic prescription etc. A case scenario was also shared and responses on decision making were obtained. The response rate was 58%. The most commonly reported reason for endodontic retreatment was under prepared/ under filled canals. Almost half of the dentists reported inappropriate decision making in retreatment. Nearly 45% participants were confined to hand instruments only and 15% were not employing any solvent. This shows that in general endodontic retreatment is not done as per the internationally accepted standards.
