INTRODUCTION This study evaluated the in vivo response of apical and periapical tissues of dogs' teeth with apical periodontitis after one-session endodontic treatment with and without antimicrobial photodynamic therapy (aPDT). METHODS Sixty root canals with experimentally induced apical periodontitis were instrumented and assigned to 4 groups receiving aPDT and root canal filling (RCF) or no...

The purpose of this study was to compare pulpal and periapical tissue reactions to electrosurgery versus formocresol pulpotomy techniques in the primary teeth of dogs. The study was conducted on 33 primary teeth of three mongrel dogs between the ages of one to three months. Each dog had three teeth treated by Formocresol Pulpotomy with Mechanical Coronal Pulp Removal (FC), three teeth treated b...

AIM The aim of the study was to investigate the presence of Treponema denticola in primary and secondary root-infected canal systems with periapical pathology and correlations with clinical signs and symptoms. METHODOLOGY Endodontic samples were obtained from canals of 102 teeth: 79 had primary endodontic disease and 23 secondary endodontic disease. For each tooth, clinical data including sym...

Apical periodontitis is an inflammatory lesion in the periodontal tissues that is caused mostly by bacterial elements derived from the infected root canal system of teeth (Core concept 7.1). In non-treated teeth apical periodontitis represents a defensive response to a primary infection in a necrotic pulp. Apical periodontitis may also develop due to a secondary infection subsequent to endodont...

Objectives: The aim of the present study was to evaluate the quality of root canal treatments and coronal restorations investigating their influence on the periapical status of endodontically-treated teeth in a Turkish population based on radiographic examination. Materials and Methods: The study included 583 patients referred for routine dental care. A total of 1125 endodontically treated teet...

OBJECTIVE The aim of this study was to determine the incidence and bacteriology of bacteremia associated with various oral and maxillofacial surgical procedures. METHODS A total of 237 patients who underwent oral and maxillofacial surgery were included in this study. Blood samples were obtained for bacteriological examination immediately after the essential steps of the surgical procedure had...

AIM To review the literature on pulp chamber and root canal obliteration in anterior teeth and to establish a clear protocol for managing teeth with fine, tortuous canal systems. SUMMARY Pulp canal obliteration (PCO) occurs commonly following traumatic injuries to teeth. Approximately 4-24% of traumatized teeth develop varying degrees of pulpal obliteration that is characterized by the appare...

Dens evaginatus is a disturbance in tooth formation that appears clinically as an accessory occlusal tuberculated cusp composed of enamel and dentin, usually enclosing pulp tissue. The tubercle often fractures or is worn away, with subsequent pulp exposure leading to pulpal inflammation, necrosis, and periapical inflammation. When this happens to an immature tooth, diagnosis may be complicated ...

This study was performed to evaluate radiographic healing of teeth with apical periodontitis, treated in one visit or in two visits (a) with or (b) without calcium hydroxide as an intracanal disinfecting medicament. The patients were assigned one of the three treatment groups by the throwing of a die. The Periapical Index (PAI) Scoring Method was used to compare differences in periapical status...

BACKGROUND This study aimed to evaluate the accuracy of two imaging methods in detecting the apical pathology in endodontically treated teeth. MATERIAL AND METHODS A clinical examination from a sample of 156 teeth of patients treated by students of masters in endodontics at the Care Center of the Faculty of Dentistry at St. Joseph University, Beirut was done after 5 years of follow-up. Perira...
