In a single visit, three canals were prepared to an apical diameter of 20/04, followed by the GentleWave® Procedure to clean and disinfect the canals. Following obturation, an isthmus communication between the fused mesiobuccal and palatal roots was noted. The unusual PAX findings were evaluated by CBCT. An apical delta containing multiple exits was discovered in the palatal canal. The GentleWave Procedure cleaned a deep split isthmus between the mesiobuccal canal and palatal canal, which otherwise may have been left uncleaned and unfilled.
"Obturation revealed the GentleWave® Procedure debrided a mid-root and apical isthmus as well as multiple exits in the palatal canal, in the apical third of the mesiobuccal-palatal root formation and connections."
The patient reported no pain two days postoperatively (after reporting a preoperative pain level of 8 on an 11-point verbal pain scale). This case highlights the clinical significance of utilizing the GentleWave Procedure for cleaning complex apical anatomy during endodontic therapy.
