Endodontic Surgery

Summary:  Purpose: to follow-up the cases classified as healed in the previous study (short term, 1yr) for an additional 5–7 yr N= 52 patients (59 roots) Materials/Methods: •A previous study by (Rubinstein RA, Kim S. 1999) demonstrated 96.8% of complete healing in 91 roots of 83 patients, within 1 yr after apical surgery using surgical […]

Purpose:  To present the frequency of periapical healing in first, second and third mandibular molar after root-end resections sealed with dentine-bonded resin composite. N= 726 mandibular molars (n= 520) Materials and methods: •The sample was collected from the authors private clinic from 1984 to 1997. •Molars with periradicular periodontitis referred for surgery. •After root-end resection […]

Purpose: To compare the success rates of teeth with three different root end materials (Amalgam, SuperEBA and IRM) N= 488 cases. Materials and methods: •The sample was collected from two private endodontic clinics. •All patients that had apicectomy with a retro-grade filling in the past 10 years •Radiographs taken at the completion of surgery and […]

Summary:  Purpose:  to correlate between radiographic size of the lesion , apical resection and retrograde filling to long-term success to periapical surgery Materials/Methods: • N : 235 patients and 333teeth  were included in this study ( 176 in the maxilla and 157 in the mandible )  •Inclusion criteria :  1- teeth with apicectomies  and ultrasound […]

Summary:  Purpose:  to preform long term evaluation of  surgically treated teeth with amalgam as retrograde filling before 1981    Materials/Methods: 1. N : 104 teeth from 96 patients recalled for follow up and evaluation with postoperative radiographs  which were taken at least 10 years ago 2.Successful criteria : if the treated tooth is functional, no […]

Purpose: To examine the relation of various preoperative and intraoperative factors to the treatment results of apical surgery in posterior teeth (treated by different operators) N = 91 patients were reexamined after having apical surgery performed on 103 premolar or molar teeth. – Preoperative and intraoperative data collected from records – surgery performed by different […]

Purpose:  to study the effect of OAC on case prognosis of teeth undergoing endodontic surgery as well as the effect of OAC on Maxillary Sinus status. • N =  314 teeth Materials/Methods: •Patients aged between 12-71 years. •Follow up at 6, 12 and 36 months after the operation; up to 12 years. •Conventional surgical procedure […]

Summary: •Purpose: To assess the influence of increasing the observation period upon healing group. •1000 teeth treated by endodontic surgery during a 9 year period: – 763: orthograde GP root filling  – 237: Retrograde with amalgam •Radiographically: one peri-apical orthoradial  exposure for each follow-up. •Most highlighted Results: 1.With longer observation time the incomplete and the […]

Summary: Data from 1000 cases treated by endodontic surgery were used to compare clinical and radiographic findings. N=120 • Radiographic healing classification was proposed with min. observation period of one year:  •G1 (complete healing): reformation of the periodontal space, bony cavity filled with bone. •G2 (incomplete healing/scar tissue): rarefaction present (decreased or stationary), irregular, asymmetrical, […]

Summary:  •Purpose:  to correlate histological and radiographical findings after endodontic surgery. •Materials/Methods: n: 70 biopsy of apices and PA tissue  (35 Max. laterals) were investigated by both methods (histological sections and RG examination). Specimens were divided according to degree of inflammation: Mild: <105 μ m2 – Moderate: from 105 μ m2 to 3X105 μ  m2 […]
