Introduction: the major goal of endodontic treatment (ET) is complete elimination and/or maximum possible reduction bacteria and irritants in root canal system (RCS). However, persistence bacterial debris refractory to therapy may leading ET failure, being necessary realize conventional or surgical retreatment. Objective: this a case report on nonsurgical management an extensive chronic periapi...

Background/Aim. Amalgam has been used for years in dentistry, but the controversy on its adverse effects, both local oral/dental tissues and systemic health, still exists. When retrograde filling apical surgery, amalgam comes close contact with periapical tissue, it is sometimes responsible induction of lesion (PL) or exacerbation. Therefore, aim study was to examine effect cytotoxicity product...

The radicular cyst is the most common inflammatory odontogenic in jaws. It a periapical lesion associated with non-vital teeth tooth-bearing regions of jaws slight male predilection. A typically asymptomatic, but if large or secondarily infected may cause swelling. usual radiographic appearance that radiolucent lesion. This case report documents rare 61-year-old mixed-density diagnosed as cyst....

BACKGROUND/AIMS Periapical periodontitis is a common oral disease caused by bacterial invasion of the tooth pulp, which usually leads to local release of pro-inflammatory cytokines and osteolytic lesion. This study is intended to examine the effect of TNF-α on BMP9-induced osteogenic differentiation of the stem cells of dental apical papilla (SCAPs). METHODS Rat model of periapical periodonti...

The main aim of this case report was to the clinical efficacy decompression for treating large periapical lesions. Tooth with cystic lesions were treated after root canal treatment. A conventional technique such as aspiration/irrigation used in case. An 18-G needle a syringe aspirate lesion. Two needles then inserted into lesion copious saline irrigation delivered from 1 and until clear express...

INTRODUCTION Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. OBJECTIVE The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. METHODS Clinical study included 49 teeth indicated ...

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...
