Actinomycosis is a chronic and less common infectious process that established by Actinomyces israilii. Involvement of faciocervical region is more common than thorasic and visceral types and typically involves the angle of mandible and with less occurrence rate the upper jaw may also be involved. Periapical lesions of maxilla that involved in this process by Actinomyces israilii are rare and c...

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...

Macrophage elastase and neutrophil elastase are involved in tissue destruction in periradicular lesions. The purpose of this study was to examine these elastases immunohistochemically during development of periradicular lesions induced in rat mandibular first molar by pulpal exposure for 7, 14, 21, 28, and 42 days. Histologically, periapical inflammation developed from 7 to 21 days and then sub...

BACKGROUND The purpose of this study was to analyze the bacterial diversity in persistent apical lesions on root-filled teeth by using culture-independent molecular methods. DESIGN Twenty surgically removed apical lesions from therapy-resistant teeth were examined for the presence of bacterial DNA using PCR targeting the 16s ribosomal RNA gene, followed by cloning and sequencing. RESULTS Ba...

OBJECTIVE This article aims to determine the incidence of periapical granuloma from extracted teeth and correlate the clinical diagnoses with the histopathological types of periapical granuloma. PATIENTS AND METHODS Over a period of eight months, a prospective study designed as a routine biopsy of recoverable periapical tissues obtained from patients who had single tooth extraction was carrie...

PURPOSE To evaluate the effect of regeneration techniques (RTs) on the outcome of periapical surgery with different protocols for different lesion types. MATERIALS AND METHODS PubMed, the Cochrane Library, and Embase were searched from the beginning of time until December 30, 2014. Studies that met the inclusion criteria were systematically evaluated, and a meta-analysis was performed. RESU...
