Introduction During damage control surgery for blunt abdominal traumata simultaneous duodenal perforations can be missed making secondary sufficient surgical treatment challenging. Endoluminal vacuum (EndoVAC™) therapy has been shown to be a revolutionary option but has anatomical and technical limits. Presentation of the case A 59-year old man with hemorrhagic shock due to rupture of the mes...

BACKGROUND Root canal irrigation carries a risk of extrusion of irrigant into the periapical tissues which can be associated with pain, swelling, and tissue damage. Studies have shown less extrusion with sonic or apical negative pressure devices compared with syringe and side-port needle or passive ultrasonic irrigation with continuous irrigant flow. This study aimed to evaluate the effectivene...

BACKGROUND Diabetes mellitus is a multisystem disease which weakens the human's immunity. Subsequently, it worsens the sequelae of apical periodontitis by raising a fierce bacterial trait due to the impaired host response. AIM This study aimed to estimate bacterial reduction after using different irrigation techniques in systemically healthy and diabetic patients with asymptomatic apical peri...

Introduction-Debridement is the aim of and also a big challenge to endodontic treatment especially in the apical portion of the root canal. Because of the complexity of the root canal anatomy and the limitations of instrumentation, irrigation has gained increasing attention and one improvement in this respect is irrigant activation. The aim of this study is to Compare the cleaning efficacy of c...

background: the purpose of this study was to compare the effi cacy of endovac irrigation system and side-vented closed ended needle (max-i probe) in removing smear layer from root canals at 1 mm and 3 mm from working length using protaper rotary instrumentation. materials and methods: a total of 50 freshly extracted maxillary central incisors were randomly divided into two groups after complete...

INTRODUCTION The purpose of this study was to evaluate the effectiveness of different irrigating methods in removing the smear layer at 1, 3, 5, and 8 mm from the apex of endodontic canals. METHODS Sixty-five extracted single-rooted human mandibular premolars were decoronated to a standardized length of 16 mm. Specimens were shaped to ProTaper F4 (Dentsply Maillefer, Ballaigues, Switzerland) ...

This study compares conventional endodontic needle irrigation, passive ultrasonic apical negative pressure and mechanical activation to remove calcium hydroxide from single straight root canals. Eighty-four mandibular premolars were prepared in a crown-down manner up size #40. Two teeth represented control, another two served as positive control. Calcium paste was placed inside The remaining ei...

immature teeth have a large apical opening and thin divergent or parallel dentinal walls; hence, with conventional needle irrigation there is a very high possibility of extrusion. this study was done to compare the apical extrusion of naocl in an immature root delivered using endovac and needle irrigation.eighty freshly extracted maxillary central incisors were decoronated followed by access ca...

AIM To evaluate the effect of intracanal cryotherapy with negative pressure irrigation (EndoVac) on postendodontic pain after vital single-visit root canal treatment (RCT). MATERIALS AND METHODS A total of 75 single-rooted teeth with single root canal were treated endodontically. After root canal preparation with Protaper Universal rotary system and irrigation, teeth were divided randomly int...

Introduction This in vitro study was designed to evaluate and compare different endodontic irrigation and activation systems for removal of the intracanal smear layer. Methods and Materials Forty recently extracted, non-carious human intact single rooted premolars were selected and divided into five groups (n=10) according to the root canal irrigation systems; syringe and needle irrigation (C...
