The application of mineral trioxide aggregates (MTA) cement during the root canal obturation is gaining concern due to its bioactive characteristic to form an apatite in dentinal tubules. In this regard, this study was to assess the biomineralization of dentinal tubules following root canal obturation by using pozzolan-based (Pz-) MTA sealer cement (EndoSeal MTA, Maruchi). Sixty curved roots (m...

AIM Maxillectomy often results in a high level of morbidity with significant psychological and functional implications for the patient. Such disabilities include inability to masticate, deglutition, and speech disturbance. Unfortunately, little is known about the nature of the speech disturbance and the influence of the class of surgical defects in this group of patients. The aims of the presen...

INTRODUCTION The aim of this study was to compare the outcome of root canal treatment using either Thermafil (TF; Dentsply Maillefer, Ballaigues, Switzerland) or the cold lateral condensation (CLC) obturation technique in teeth with periapical lesions and to investigate the influence on postoperative pain and treatment outcomes. METHODS After standardized root canal preparation technique, 112...

OBJECTIVE To assess postoperative pain in endodontic therapy and its association with clinical factors such as gender, age, tooth type, pulpal diagnosis, and preoperative pain, length of obturation and sealer extrusion. STUDY DESIGN Cross-Sectional study. PLACE AND DURATION OF STUDY Dental section of the Aga khan university hospital, Karachi, Pakistan from January to December 2009. METHOD...

This study was carried out to assess the success rate of apicectomy of anterior and premolar teeth. Out of 336 patients, who had undergone apicectomy in a private practice between 1997–2001, only 256 patients (76.2%) completed the two years recall visits; which was the minimum time recommended in this study to judge whether the operation was successful or not. The age range of the patients was ...

STATEMENT OF PROBLEM Crowns have been considered the restoration of choice for endodontically treated teeth, but their selection has been based primarily on anecdotal evidence. PURPOSE This study tested the hypothesis that crown placement (coronal coverage) is associated with improved survival of endodontically treated teeth when preaccess, endodontic, and restorative factors are controlled. ...

Histological periapical healing of infected roots obturated in one-step or with prior calcium hydroxide (Ca(OH)2) disinfection was compared. Seventy-two roots of vital dog teeth were instrumented to ISO size 45. Sixty roots were infected with dental plaque and closed. Six weeks later, apical periodontitis was radiographically confirmed in the infected roots. The teeth were divided into the foll...

the results of the initial study. It was concluded that the apical fluids, with their primary source being blood serum, diffuse into the empty canal spaces, stagnate, undergo degradation and then act as a physicochemical irritant when they diffuse back into periapical tissues. In support of this theory of stagnation, in 1955 Dow and Ingle showed that the majority of the endodontic failures were...
