AIM The present study was undertaken to compare two methods of obturation in primary teeth by using lentulospirals and pressure syringe, radiographically. MATERIALS AND METHODS Sixty teeth in subjects with mean age of 5.88 ± 1.58 years were obturated randomly using two different obturating techniques, i.e. group I: Thirty teeth obturated with pressure syringe, and group II: Thirty teeth obtur...

OBJECTIVE To compare the technical quality of root canal obturation in relation to rotary and manual root canal preparation techniques. STUDY DESIGN Cross sectional, analytical study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital Karachi from January till December 2011. METHODOLOGY Data was retrospectively retrieved by periapical radiographs of 60 root canal treated molars ...

Endodontic treatment, when performed with proper instrumentation, canal disinfection, and obturation can be a tremendous service to a dental patient and a key component of any restorative practice. It can be complicated by factors such as poor diagnosis, incomplete canal debridement, ineffective obturation, bacterial invasion, and insufficient restorative treatment. Retreatment or even tooth lo...

The role of obturation in root canal treatment, although considered secondary to debridement and disinfection, still remains a critical stage for a successful outcome. The aim of obturation is to seal the periradicular tissues from the residual microorganisms left in the root canal system after chemomechanical debridement. Obturation of the root canal space has been performed using various tech...

an important goal in endodontic treatment. To achieve this goal, the root canal filling must seal the pulp space both apically and laterally to prevent further apical irritation from incomplete elimination of bacterial products.1 In the past, the adequacy of root canal filling procedure was primarily based on its vertical appearance on the dental radiograph and whether the material had reached ...

Article Type: Original Article Introduction: There is a direct relationship between the quality of root canal obturation and success of endodontic therapy. The aim of the present study was to assess the quality of canal obturation performed by undergraduate dental students at the Faculty of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran. Materials and Methods: Records of 200 e...

The aim of this study was to examine and compare vertical forces exerted during root canal obturation with the cold lateral condensation technique, Thermafil technique and ProTaper guttapercha. Fourty-five single-rooted permanent teeth were used in the study. All specimens were instrumented using the ProTaper rotating technique and were randomly divided into three experimental groups (n = 15 pe...

BACKGROUND: Until recently the most accepted technique of doing root canal treatment stresses multiple visit procedure. Most schools also concentrated upon teaching the multi-visit concept. However, it has now been reported that the procedure of single visit treatment is advocated by at least 70% of schools in all geographical areas. It was therefore the aims of the present study to find the in...

AIM To compare the average sealer cement film thickness and the extent and pattern of sealer penetration into dentinal tubules in association with four obturation techniques in curved root canals. METHODOLOGY Mesial canals of 44 extracted mandibular molars were randomly divided among the SimpliFill, continuous wave, Thermafil and 0.04 matched taper (master cones) lateral compaction obturation...

INTRODUCTION The choice of single- versus multiple-visit root canal treatment for infected teeth is in dispute. The purpose of this systematic review was to compare the healing rate and post-obturation pain of single- versus multiple-visit root canal treatment for teeth with infected root canals. METHODS An exhaustive literature search combined with specified inclusion criteria was performed ...
