AIM The aim of this study was to investigate the prevalence of additional canals in maxillary first molars in a selected population in Nigeria. METHODS AND MATERIALS One hundred extracted teeth were collected from the Pedodontic and Oral Surgery clinics of the University College Hospital in Ibadan, Nigeria. The teeth were identified and their root planed to remove adherent soft tissues. Each ...

a rare case of ascaris coming out through the anterior abdominal wall is reported here. a 40‑year‑old female had undergone dilatation and curettage by a quack. on the second day she presented with presented with features of peritonitis. she was explored. resection anastomosis of the ileum was done for multiple perforations of the ileum. patient developed a fistula in the anterior abdominal wall...

The removal of fractured rotary nickel-titanium instruments from small, curved root canals is one of the most complex operative procedures in endodontics. There have been many different devices and techniques developed to remove fractured instruments, but none are consistently successful and all show a high incidence of canal damage such as perforation. A technique using a staging platform and ...

A case report is presented on transplantation of a left third molar to replace a right second molar lost due to large furcation perforation. Two weeks after surgery, a reentry surgical procedure was performed on the furcation defect of the second molar to remove membrane and retrieve proliferating periodontal tissue. The left third molar and proliferating periodontal tissue were then transplant...

introduction: the purpose of this study was to evaluate the radiographic quality of root canal fillings by fourth-, fifth-, and sixth-year undergraduate students at tabriz faculty of dentistry between 2006 and 2012. methods and materials: a total of 1183 root canal fillings in 620 teeth were evaluated by two investigators (and in case of disagreement by a third investigator) regarding the prese...

Introduction: Foreign bodies in the esophagus are considered to be a life-threatening condition in adults and children because of esophageal perforation, chemical pneumonitis, airway obstruction, and development of a fistula, leading to high morbidity and mortality with this condition. Most cases present with immediate symptoms. However, in rare cases, the foreign body can migrate within the t...

AIM To investigate the probability of and factors influencing tooth survival following primary (1°RCTx) or secondary (2°RCTx) root canal treatment. METHODOLOGY This prospective study involved annual follow-up of 2 (100%) to 4 years (50%) of 1°RCTx (759 teeth, 572 patients) and 2°RCTx (858 teeth, 642 patients) carried out by Endodontic postgraduate students. Pre-, intra- and post-operative dat...

herein, we present the case of a 45-years-old woman with a foreign body (dental prosthesis) ingestion lodged in the esophagus(figure.1). the foreign body was extracted by rigid esophagoscopy after severe manipulation. in 24 hours, the patient became febrile with emphysema in the neck. laboratory data showed leukocytosis and ct scan revealed signs of esophageal perforation(figure.2). surgical ex...

BioAggregate is a new product that was formulated for root-end filling, perforation repair, and pulp capping. This study examined the chemical differences between white mineral trioxide aggregate (MTA) and BioAggregate in both powder and set forms using X-ray diffraction. The results showed that white MTA and BioAggregate have a similar chemical composition with some differences: BioAggregate c...
