OBJECTIVE This study evaluated the treatment outcome after periapical surgery with the use of 2 different retrograde root-filling materials and the influence of 3 pre- and perioperative variables on the periapical healing. STUDY DESIGN Two hundred six teeth in 164 patients were randomly allocated to receive either IRM or Super-EBA as a retrograde root-end seal. The teeth were reviewed 12 mont...

On healing after periapical surgery and different retrograde root-filling materials. A clinical and histological study. Aims: The outcome from conventional endodontic therapy does not always result in a healing of the periapical area, thus leaving a remaining lesion with or without symptoms. The primary treatment alternative is a revision of the orthograde root-filling if applicable. A second t...

Root amputation and retrograde filling of pulp canals is a useful technique in the treatment of periapical dental infections in horses, thus allowing tooth preservation. The limitations of the technique are the need for careful case selection and the difficulty in creating a hermetic apical seal. Authors’ addresses: Royal Veterinary College, Hawkshead Lane, North Mymms, Hatfield, Hertfordshire,...

Purpose: To evaluate the ability of BiodentineTM as a retrograde root-end filling in conjunction with a well-documented periapical surgery protocol in a clinical case series study. Material and Methods: Thirteen teeth in 13 patients referred for periapical surgery were included in the study. Teeth with obvious signs of root-fracture or apical-marginal communications were excluded from the study...

Background. This study evaluated the ability of Kryptonite bone cement in sealing retrograde cavities. Methods. The root canals of one hundred extracted human maxillary incisor teeth were instrumented up to master apical file #40 using Mtwo rotary system and obturated with gutta-percha and AHPlus sealer by cold lateral compaction method. The specimens were assigned to one control group and four...

The aim of this study has been to visualize the aqueous outflow system in patients affected by primary open angle glaucoma. A solution of indocyanine green (ICG) plus high viscosity viscoelastic solution was injected into the Schlemm canal during surgery in 10 glaucomatous patients undergoing canaloplasty. Soon after injection of the dye the borders of the scleral flap were completely stained d...

BACKGROUND/AIMS Hemobilia is a rare cause of upper gastrointestinal bleeding. Endoscopic retrograde cholangiopancreaticography (ERCP) is considered to be an excellent diagnostic and treatment modality. Thirty-seven cases of hemobilia with different underlying pathologies were analyzed to illustrate clinical features and to evaluate the role of endoscopic management. METHODS A total of 37 pati...

The purpose of this study was to compare root-end sealing using 4-META/MMA-TBB resin with that using conventional retrograde root filling technique, and thereby determine if 4-META/MMA-TBB resin offers long-term prevention against dye leakage from the root canal of human teeth. Thirty-five teeth had the apical 2.5 mm of the root resected. In the Sealing (SB) group, 4-META/MMA-TBB resin was appl...
