Συγκριτική μελέτη της επούλωσης του χειρουργικού τραύματος ακρορριζεκτομών με ανάστροφη έμφραξη αμαλγάματος ακρορριζεκτομών με ανάστροφη έμφραξη υαλοϊονομερούς κονίας και ακρορριζεκτόμων με ενδομυλική έμφραξη υαλοϊονομερούς κονίας - κώνου γουταπέρκας

摘要

IN THIS THESIS, WE COMPARE THE HEALING RESULTS BETWEEN THREE GROUPS OF APICOECTOMIZED TEETH. GROUP A, INCLUDES FIFTEEN APICOCECTOMIZED TEETH, AFTER AMALGAM RETROGRADE ROOT CANAL FILLINGS. THE HEALING RESULTS, AFTER ONE YEAR FOLLOW UP WITH CLINICAL AND RADIOGRAPHIC CRITERIA WERE FOUND TO BE 60% FOR THE COMPLETE HEALING CASES, 26,7% FOR THE UNCERTAIN HEALING CASES AND 13,3% FOR THE FAILURES. GROUP B, INCLUDES FIFTEEN APICOECTOMIZED TEETH, AFTER GLASS-IONOMER CEMENT RETROGRADE ROOT CANAL FILLINGS. THE HEALING RESULTS AFTER ONE YEAR FOLLOW UP WITH CLINICAL AND RADIOGRAPHIC CRITERIA WERE FOUND TO BE 66,7% FOR THE COMPLETE HEALINGCASES, 26,7% FOR THE UNCERTAIN HEALING CASES AND 6,6% FOR THE FAILURES. GROUP C, INCLUDES FIFTEEN APICOECTOMIZED TEETH, AFTER GLASS-IONOMER CEMENT ORTHOGRADEROOT CANAL FILLINGS. THE HEALING RESULTS, AFTER ONE YEAR FOLLOW UP WITH CLINICAL AND RADIOGRAPHIC CRITERIA WERE FOUND TO BE 80% FOR THE COMPLETE HEALING CASES, 13,3% FOR THE UNCERTAIN HEALING CASES AND 6,7% FOR THE FAILURES. HEALING RESULTS IN APICOECTOMIES AFTER ORTHOGRADE ROOT CANAL FILLINGS WERE FOUND MUCH BETTER, THAN THE RESULTS OF APICOECTOMIES AFTER RETROGRADE ROOT CANAL FILLINGS. THEHEALING RESULTS, WERE SIMILAR FOR THE TWO GROUPS OF APICOECTOMIES, AFTER RETROGRADE ROOT CANAL FILLINGS. THE FINAL CONCLUSION IS, THAT GLASS-IONOMER CEMENT IS A FILLING MATERIAL, THAT CAN BE USED WITH SUCCESS IN APICOECTOMIES AFTER ORTHOGRADE, AS WELL AS, RETROGRADE ROOT CANAL FILLINGS.
