This cross-sectional study determined the prevalence of apical periodontitis in 1035 root canal-treated teeth from adult French patients and investigated the influence of the quality of canal fillings and coronal restorations on the periradicular status. Periapical radiographs were used for analyses, and teeth were classified as healthy or diseased according to the periapical index scoring syst...

Dens invaginations are a rare developmental defect most commonly affecting maxillary lateral incisors, with very few reported cases in mandibular teeth. We describe a rare case of bilateral first mandibular premolar dens invaginations type I, where apparently health teeth presented with periapical pathology.

Objectives: This study aimed to compare the efficacy of panoramic radiography and the buccal object rule in intraoral periapical radiography for localization of impacted maxillary canine teeth. Methods: A total of 20 panoramic radiographs depicting 28 displaced maxillary canines were evaluated. The ratio of the mesiodistal width of the impacted canine to the mesiodistal width of the...

The influence of various factors that may affect the outcome of root canal therapy was evaluated in 356 patients 8 to 10 yr after the treatment. The results of treatment were directly dependent on the preoperative status of the pulp and periapical tissues. The rate of success for cases with vital or nonvital pulps but having no periapical radiolucency exceeded 96%, whereas only 86% of the cases...

Introduction. This paper describes a case of bone augmentation with combination of Platelet-Rich Fibrin (PRF) and β-TCP for treatment of chronic periapical cyst. The case was followed for 12 months. Methods. Patient presented with chronic periapical lesion in maxillary anterior teeth with history of trauma 8 years back. Radiographically, a periapical cyst was seen in relation to maxillary left ...

BACKGROUND A 45-year-old male patient reported with periorbital swelling of eyelids, of the left eye, foul smelling nasal discharge and a pus draining sinus on the left lower eyelid area. CASE DESCRIPTION The patient gave history of pain in the left upper first molar tooth 1 week back. His intraoral exami...

D IAGNOSIS of periapical areas of rarefaction has always been a problem to the oral surgeon and general practitioner. A review of the literature reveals few studieF of apical roentgenolucent areas in the last 10 years. These investigations have concerned themselves mainly with teeth that have had extensive restorative and endodontic treatment. A study was undertaken to (I) evaluate, roentgenogr...

AIM The aim of the study was to assess the prevalence of apical periodontitis and quality of root canal fillings in an adult Riga subpopulation. MATERIALS AND METHODS Panoramic radiographs of Latvian adults 35-44 year old attending a private dental clinic for the first time during the period of 2004-2008 were included in the study. Totally, 312 out of 1248 panoramic radiographs were randomly ...

An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively. Correct diagnosis and treatment planning are fundamental to treatment of dens invaginatus. Periapical surgery is indicated in cases where a nonsurgical approach fails. A case...
