The purpose of this review was two-fold: (a) to determine which retrograde obturation material(s) best prevents dye/ink penetration in vitro; and (b) to determine whether in vitro results agree with in vivo results. A MEDLINE search was conducted to identify in vitro studies published between January 1966 and October, week 4, 2003, conducted on human teeth, and published in English, German, or ...

Successful root canal treatment is based on diagnosis, treatment planning, knowledge of tooth anatomy, and the traditional concepts of debridement, sterilization, and obturation. Several obturation techniques are available for root canal treatment. The choice depends on the canal anatomy and the unique objectives of treatment in each case. The two basic obturation procedures are lateral condens...

This prospective study was undertaken to determine the incidence of post obturation pain related to root canal treatment of asymptomatic non-vital maxillary central incisor teeth that were prepared and filled in one visit using two different manual rootcanal preparation techniques: the step-back and the step-down and to determine the relationship, if any between post obturation pain and root ca...

C C bstract he purpose of this study was to evaluate clinical utcome differences of root canal obturation by warm utta-percha (GP) or cold lateral condensation (CLC) hrough a systematic review and meta-analysis. There ere 10 clinical studies evaluated. Postoperative pain, ong-term outcomes, obturation quality, and overextenion were the characteristics investigated. The results uggest that the t...

The purpose of this study was to evaluate clinical outcome differences of root canal obturation by warm gutta-percha (GP) or cold lateral condensation (CLC) through a systematic review and meta-analysis. There were 10 clinical studies evaluated. Postoperative pain, long-term outcomes, obturation quality, and overextension were the characteristics investigated. The results suggest that the two o...

Currently, although ultrasonics (US) is used in dentistry for therapeutic and diagnostic applications as well as for cleaning of instruments before sterilization, its main use is for scaling and root planing of teeth and in root canal therapy, both for orthograde and retrograde therapy. Both in conventional and surgical treatments, US in endodontics has enhanced quality of clinical procedures a...

To evaluate the effectiveness of the ProTaper and Mtwo retreatment systems for removal of resin-based obturation techniques during retreatment. A total of 160 maxillary anterior teeth were enlarged to size 30 using ProTaper and Mtwo rotary instruments. Teeth were randomly divided into eight groups. Resilon + Epiphany, gutta-percha + Epiphany, gutta-percha + AH Plus and gutta-percha + Kerr Pulp ...

Aim: To evaluate invitro the effect of post obturation materials on reinforcement of peri-cervical dentin (PCD) Materials and Method : Sixty extracted, maxillary premolar teeth were selected.After preparation of standardized access, crowns were resected so that a final dimension of 4 mm from one mm below highest point of proximal cervical line was achieved. Then, the enamel was carefully remove...

The use of gutta-percha as a standard obturation material over more than 100 years has made little changes in the obturation technique. With the advent of bonding and composite resins as a routine restorative material, the concept of bonded obturation has come into picture. The Resilon-Epiphany system has brought about a paradigm shift in the conventional obturation technique. This article expl...
