Abstract
Aim: Although there are many materials that can be used for retrograde filling in surgical endodontics, none of them can be regarded as an ideal material yet. The purpose of this study was to compare the surface topography of three different root-end filling materials.Methods: 36 extracted single rooted human incisor teeth were cleaned and decoronated to standardized 10 mm root lengths. The root segments were prepared and 2 mm apical resection were performed. The samples were randomly separeted to three groups (Group A: Ca(OH)2, Group B: MTA Angelus, Group C: ProRoot MTA), each comprised of 12 roots. Materials were placed as 2 mm apical barriers and obturated with guttapercha and AH-Plus sealer. Each group dimidiated two subgroups (A1,A2,B1,B2,C1,C2). Groups A1,B1,C1 were stored in normal saline (NS), groups A2,B2,C2 were stored in neutral phosphate buffer saline (NPBS) solution and samples were incubated at 370C for 2 weeks. Stereomicroscope (32X) was used to photograph the root-end filling.Results: All specimens demonstrated white crystals formation and sediment over the root-end filling materials and on the superficial border of the root-end cavities’ wall as a white plague. A2,B2,C2 samples have more crystal sediment on root-end fillings than samples A1,B1,C1. Dissolution and corrosion were observed in groups A1, A2.Conclusions: The results of this study revealed that calcium hydroxide is more resorbable than MTA Angelus and ProRoot MTA. The crystals formation and precipitation were observed in neutral phosphate buffer saline solution was more than normal saline solution for all groups as a hydroxiapatite crystals.
Highlights
Endodontic surgery is performed in cases when treatment with orthograde root canal is treatment-resistant to periradicular inflammation or nonsurgical root canal treatment is unsuccessful [1,2]
Various materials are invariably used for instance amalgam, bonding systems, zinc oxide eugenol cements, glass ionomer cements, and calcium-silicate cements, all of which are commonly named as mineral trioxide aggregate based cements [5,6]
The crystal sediments on root-end fillings in the samples of Calcium Hydroxide, mineral trioxide aggregate (MTA) Angelus and ProRoot MTA which were stored in normal saline solution (A1, B1, C1) were less than Calcium Hydroxide, MTA Angelus and ProRoot MTA which were stored in neutral phosphate buffer saline solution (A2, B2, C2)
Summary
Endodontic surgery is performed in cases when treatment with orthograde root canal is treatment-resistant to periradicular inflammation or nonsurgical root canal treatment is unsuccessful [1,2]. A root-end cavity preparation is performed a retrograde filling material is used for filling. The periradicular surgery aims to block the ways in which transmission can occur between the root canal system and surrounding tissues [3]. Surgical endodontic treatment technique is a feasible treatment option, and the type of root-end filling material can affect the end result [4]. Root-end filling materials get in touch with periapical bone tissue after apex resection surgery. Various materials are invariably used for instance amalgam, bonding systems, zinc oxide eugenol cements, glass ionomer cements, and calcium-silicate cements, all of which are commonly named as mineral trioxide aggregate based cements [5,6]. An ideal root-end filling material should demonstrate particular characteristics.
