Examining the Effect of Different Filling Techniques on Healing in Lesional Teeth

Brief Summary

Microorganisms are an important factor in the development of periradicular diseases. The goal of non-surgical endodontic treatment is to eliminate microorganisms and their byproducts from the root canal system and to create an effective barrier between the root canal system and surrounding tissues. If there is no healing in the periradicular tissues after non-surgical endodontic treatment or if retreatment becomes impossible, surgical endodontic treatment is required. Apical resection is a surgical technique that involves removing the root tip of the tooth and closing the apical portion of the root canal system. An ideal retrograde filling material should be non-toxic, non-carcinogenic and biocompatible. It must also have dimensional stability and sealing properties. Amalgam, glass ionomer cements, and zinc oxide-eugenol based materials have been used for root end fillings in periapical surgery, but the desired success was not achieved. Today, Mineral Trioxide Aggregate (MTA) is preferred as a retrograde filling material due to its superior sealing properties, ability to harden in the presence of blood and moisture, antibacterial effects, biocompatibility and radiopacity. In the researchers' study, the effect of apical resection after orthograde canal filling and retrograde canal filling during apical resection on postoperative recovery will be compared. In both canal filling techniques, Sure-Seal Root MTA (Sure Dent Corporation-Korea) will be used as the filling material. Sure-Seal Root MTA is a calcium silicate based paste that is typically pre-mixed and ready to apply, exhibits excellent physical properties and does not show shrinkage during the curing process. As the manufacturer states, it is hydrophilic, biocompatible, has ideal setting and working time. Our faculty has piezosurgical ultrasonics (Mectron ®, Grassobbio BG, Italy). After the root tip resection is performed, the retrograde cavity will be prepared with Woodpecker ultrasonic tips (Guilin, China) compatible with this device. In our study using these materials and devices, a comparative analysis of the effects of different canal filling techniques on lesion healing and improvement in clinical symptoms will be made.
