“…Reciproc extruded significantly more debris than all other files (P < .05). Previous studies showed that the amount of apical debris extrusion can be related to the root canal anatomy and/or the instrumentation technique, and currently no method completely avoids debris extrusion (13,(17)(18)(19)(20)(21)(22)(23).…”

Background: Pain after root canal treatment is a challenging problem for the operative dentists over the last few years. The development of pain is dependent on the intensity of tissue damage. Inflammation is characterized by a series of vascular events in response to tissue injury. The release of mediators is responsible for much of the pain. The rationale of this study is to use NSAIDs alone or in combination with dexamethasone to reduce post treatment swelling and pain following endodontic therapy. The objective of the study was to compare the frequency of post obturation pain by using ibuprofen or ibuprofen/ dexamethasone infiltration in single visit endodontic cases.Methods: This study was carried out in the Operative Dentistry, Department (AFID), Rawalpindi, Pakistan from December 2015 to May 2016 after approval from the Institutional Ethical Review Board. After an informed consent, 128 patients fulfilling inclusion criteria were divided in to two equal groups. In Group A, after root canal treatment, an additional single shot local infiltration of 0.5 mg dexamethasone was given in periapical area. Both the patient groups were prescribed ibuprofen 400 mg three times a day. Patient’s pain response was recorded after 24 hours of treatment, using visual analogue scale. Data was analyzed using SPSS version 17.Results: After 24 hours, 6 (9.4%) patients showed the pain in group A while 16 (25.0%) patients complained of pain in group B. Conclusions: The results of this study showed, group A showed less postoperative pain as compared to group B where only ibuprofen was given.

“…4 Various studies have shown that crown down technique leads to minimum apical extrusion of debris but various instrument designs may affect the extrusion. 5 A thorough comparison of various rotary systems in extrusion of debris and irrigant may be beneficial so that the best instrument with the lowest incidence of extrusion and post-operative flare-up may be selected.…”

Aims and objective: The purpose of this study was to evaluate and compare the apical extrusion of debris and irrigant using various rotary instruments with crown down technique in the instrumentation of root canals.Material and Method: Thirty freshly extracted human permanent straight rooted mandibular premolars with minimum root curvature of 0e10 were divided in three groups with 10 teeth in each group. Each group was instrumented using one of the three rotary instrumentation systems: Rotary Hero shapers, Rotary ProTaper and Rotary Mtwo. One ml of sterile water was used as an irrigant after using each instrument. Debris extruded was collected in pre weighed glass vials and the extruded irrigant was measured quantitatively by Myers and Montgomery method and was later evaporated. The weight of the dry extruded debris was calculated by comparing the pre and post instrumentation weight of glass vials for each group.Statistical analysis: Statistical analysis was done by using by a KruskaleWallis One-way ANOVA test.Results: Statistical analysis showed that all the rotary instruments used in this study caused apical extrusion of debris and irrigant. A Statistically significant difference was observed with Rotary ProTaper and Rotary Mtwo groups when compared with Rotary Hero shapers. But no significant difference was observed between Rotary ProTaper and Rotary Mtwo groups. Conclusion:After instrumentation with different rotary instruments, Hero shapers showed a less apical extrusion of debris and irrigant.

Apical extrusion of intracanal bacteria following use of various instrumentation techniques

Abstract: All instrumentation techniques extruded intracanal bacteria apically. No significant difference was found in the number of CFU among the engine-driven techniques; manual techniques extruded significantly more microorganisms.
