Non-surgical endodontics in retreatment of periapical lesions – two representative case reports
نویسندگان
چکیده
This article reports non-surgical endodontic retreatment of two patients with persistent or recurrent periapical lesions, who had previously undergone surgical and non-surgical endodontic therapy respectively. It further discusses and reviews the relevance of classification of periapical lesions, the explanation behind healing of periapical lesions by endodontic therapy alone, causes of persistence of periapical lesions, choice of treatment modalities (whether surgical or non - surgical) and materials such as intracanal medicaments and irrigants for optimal healing. Key words:Non-surgical, retreatment, periapical, calcium hydroxide, chlorhexidine irrigation.

Incidence of periradicular pathoses in endodontic treatment failures.
Biopsy reports from 150 periradicular tissue specimens obtained from teeth refractory to nonsurgical endodontic therapy were reviewed. The specimens were submitted by postdoctoral dental students in the Department of Endodontics, and the biopsy reports were prepared by oral pathologists at the University of Texas Health Science Center at San Antonio. The study found that 59.3% of the periradicu...
متن کاملEffect of Ibuprofen on IL-1β, TNF-α and PGE2 Levels in Periapical Exudates: A Double Blinded Clinical Trial
Background: Bone resorption is one of the main features of inflammatory periapical lesions and is mainly mediated by interleukin-1 beta (IL-1β), tumor necrosis factoralpha (TNF-α) and prostaglandin-E2 (PGE2). Recent investigations of these lesions revealed that pharmacological modulation may be possible. Objective: The aim of this study was to evaluate the effect of Ibuprofen on IL-1β, TNF-α an...
متن کاملDiode laser assisted endodontic treatments in periapical lesions repair: case series
Background and Aim: Bacterial disinfection is considered as the primary etiology of pulpal and periapical lesions and as the result, adequate elimination of such infections is one of the purposes of root canal treatment; But since this purpose is impossible to achieve, reducing the bacterial load seems to be as a rational goal. Diode lasers have made their way into endodontics for better disinf...
متن کاملUse of bovine colostrum in periapical defects following surgical endodontics: Two case reports
Periapical lesions are the most common pathological conditions involving teeth which often require surgical intervention. To achieve optimal healing both clinically and radiographically, bone grafts and barrier membranes have been used to fill the periapical defect after degranulation of the lesion. Colostrum is one of the new materials, which has osteoinductive or regenerative potential. The p...
متن کاملClinical and Patient-centered Outcomes of Nonsurgical Root Canal Retreatment in First Molars Using Contemporary Techniques.
INTRODUCTION There have been many recent technical advances in modern endodontics that have the potential to affect treatment outcomes. Reports on treatment outcomes using contemporary techniques are relatively scarce, especially in the field of nonsurgical retreatment. The purpose of this study was to determine the success of nonsurgical root canal retreatment in molars using contemporary endo...
