HYBROSONIC : The name derives from Heat + Sonic Vibration. The invention relates to Root Canal Obturating Device for fillling of Root Canal after removal of tooth pulp. Root canal treatment is the removal of tooth’s pulp, a small thread like tissue in the centre of the tooth. Proper root canal filling should achieve three dimensional obturation of the root canal space to prevent micro organisms...
the main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. failure to find and fill a canal contributes toward the failure of endodontic therapy .the root canal anatomy of mandibular first molars is complex. studies of the morphologic structure of root canal systems have d...
Besides the risk of filling material extrusion throughout the apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements of the apical constriction. These situations pose a challenge to root canal filling. This paper describes the root canal filling of a maxillary right canine with an overinstrumented apex, complete loss of the apical stop...
Root canal filling materials, including sealercement and obturation points or cones, are used in root canal treatment to occlude the apical portion of the canal. These will block the dentinal tubules preventing passage of tissue fluids, toxins, and microorganisms into the root canal space. Many investigators have demonstrated the importance of a sealer cement for effective root canal obturation...
this case report presents conservative management of unset mineral trioxide aggregate (mta) after being placed as a root-end filling material following periapical surgery. periapical surgery was indicated for a maxillary lateral incisor of a 15-year-old male due to persistent exudate and a large periapical lesion. during surgery angelus mta was placed as root-end filling. the next session it wa...
Aims The primary goals of endodontic treatment are to debride and disinfect the root canal space to the greatest possible extent, and to seal the canals as effectively as possible, aiming to establish or maintain healthy periapical tissues. Although initial root canal therapy has been shown to be a predictable procedure with a high degree of success, failure can occur after treatment. Lack of h...
INTRODUCTION Rotary instruments that are used for retreatment are very effective, but most of them leave root filling residue in the canal. The aim of this study was to evaluate the efficacy of removing gutta-percha-based root fillings with ProTaper retreatment files (Dentsply Maillefer, Ballaigues, Switzerland) followed by F1 and F2 ProTaper instruments and to compare these results with those ...
introduction: pulpectomy is a conservative treatment plan for primary necrotic teeth and zinc oxide eugenol is still a good choice as root canal filling material but long term studies on poor prognosis molars are limited and almost contradictory. the purpose of this study is to evaluate the clinical and radiographical success rate of pulpectomy of necrotic primary molars using zoe as the root c...
OBJECTIVES The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in the removal of Gutta-percha (GP) and sealer from the root canal walls with or without solvent. MATERIALS AND METHODS Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I...
OBJECTIVE To evaluate the discrepancy of root canal filling (RCF) measurements obtained from original root specimens and cone-beam computed tomography (CBCT) images. MATERIAL AND METHODS Seventy-two human maxillary anterior teeth were prepared up to an ISO #50 K-File 1 mm short of the apical foramen. Thus, the teeth were randomly divided into 8 groups, according to the root canal filling mate...
