Anorectal abscesses are commonly encountered in clinical surgical practice. These abscesses require surgical management. Supralevator abscesses are thought to originate either from an ischiorectal or intersphincteric abscess extension or from an intraperitoneal source. These abscesses are quite uncommon and present a difficult surgical problem. We present a case here of a 42-year-old female wit...

A posterior auricular abscess in a 3-year-old girl was confirmed to have been caused by an unusual organism, Turicella otitidis.

Vascular endothelial growth factor (VEGF)-induced angiogenesis contributes to inflammatory bone resorption in humans. Widely documented antagonists include antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs). The purpose of this study was investigate the effect these on proangiogenic VEGF levels periradicular lesions. Periapical tissue biopsies were obtained from 42 patients with chr...

BACKGROUND Apical periodontitis (AP) is one of the most prevalent diseases of the teeth. Treatment of AP is based on the removal of the cause, i.e., bacteria from the root canals. Achievement of adequate bacterial eradication in one appointment treatment remains a controversy. AIM This prospective study was conducted with the objective to compare the periapical healing of teeth with AP treate...

INTRODUCTION Cholesterol clefts are common histologic findings in periapical biopsies; they have a reported incidence in periapical periodontitis of up to 44%. Cholesterol crystals are also recognized in advanced atherosclerotic plaques in humans. Male sex, genetic abnormalities, and age have been associated with advanced atherosclerotic lesions. Among these nonmodifiable risk factors, age is t...

The aim of this study was to evaluate the morphological effects of diode laser irradiation in the experimentally produced periapical lesion in rat. Fourteen adult male Sprague-Dawley rats weighing approximately 200 gm each were used. Pulp was extirpated from the mesial root of the maxillary first molar using 06 to 25 mm conventional reamers and files. After extirpation, the root canal was expos...

OBJECTIVES Our aim was to compare periapical radiography and cone beam CT (CBCT) for assessment of the periapical bone defect 1 week and 12 months after root-end resection. METHODS 50 patients (58 teeth) with a persisting apical periodontitis in a root-filled tooth (incisor, canine or premolar) were treated with root-end resection. 1 week and 12 months post-operatively, a CBCT scan (NewTom 3G...

Dental traumatic injuries may affect the teeth and alveolar bone directly or indirectly. Pulpal necrosis and chronic and apical periodontitis with cystic changes are the most common sequelae of the dental traumatic injuries, if the teeth are not treated immediately. This case report focuses on the conventional and surgical management of mandibular central incisors. A twenty-four-year-old male p...

BACKGROUND/AIMS Bacterial infection is a major cause of periapical periodontitis. Eradication of these microorganisms from apical lesions is essential to the success of endodontic treatment. The aim of this study was to clarify the molecular interaction between Fusobacterium nucleatum, Porphyromonas gingivalis and other microorganisms associated with periapical periodontitis. METHODS Microorg...
