ABSTRACT
Aim: Antibiotic loaded bone cement has been used extensively in orthopaedic surgery and in the treatment of osseous defects resulting from joint infection, osteomyelitis, osteitis. No endodontic investigation has used this type of material in the treatment of bony resorptive defects of the periapical lesions associated with failed endodontic therapy or periapical surgery. Therefore, this study was conducted with the use of gentamycin loaded bone cement, to assess healing ability of osseous defects in apical re-surgery cases after failed apical surgery. Methods: In all patients periapical lesions were surgically removed and gentamicin loaded bone cement was used as root end filling material and then carefully packed without pressure into the bony defect. Results: Long-term recall demonstrated clinical and radiographic healing and good tolerance of bone fill material by the periapical tissues. Conclusion: results from this study shows that gentamicin loaded bone cement is a biocompatible material and can be used effectively in apical resurgery cases for treating recalcitrant infectious osseous defects of periapical lesions associated with failed periapical surgery.
ABSTRACT
Background: Aim: To study the outcome of single visit surgical extrusion and immediate aesthetic restoration of 15 cases of crown root fracture. Methods: Involved a conventional surgical extrusion method with elevators and stabilization with semi rigid fiber splint followed by immediate aesthetic composite buildup for restoration of aesthetics. Root canal treatment was completed after 3 weeks of Calcium hydroxide intracanal medicament. Results: Follow up examinations varying between 6 and 18 months, revealed no evident radiographic and clinical signs of root resorption, periapical disease and more important, marginal bone loss/gingival recession in any case. Conclusion: Highly favorable results of this clinical study reveal that single visit surgical extrusion with immediate aesthetics of crown root fractures may be an alternative to time consuming orthodontic extrusion which may create severe esthetic and emotional problems to patient.
