Frequency of post obturation pain by using ibuprofen and ibuprofen/dexamethasone infiltration in single visit root canal treatment cases

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.

Quality of root canal fillings using three gutta-percha obturation techniques

OBJECTIVES: The goal of this study was to compare the density of gutta-percha root fillings obturated with the following techniques: cold lateral (CL) compaction, ultrasonic lateral (UL) compaction, and warm vertical (WV) compaction. MATERIALS AND METHODS: Thirty-three extracted mandibular first molars, with two separate mesial canals in each, were selected. After instrumentation, the canals were stratified into three groups based on canal length and curvature, and underwent obturation with one of the techniques. No sealer was used in order to avoid masking any voids. The teeth were imaged pre- and post-obturation using micro-computed tomography. The reconstructed three-dimensional images were analyzed volumetrically to determine the amount of gutta-percha present in every 2 mm segment of the canal. P values < 0.05 were considered to indicate statistical significance. RESULTS: The overall mean volume fraction of gutta-percha was 68.51 +/- 6.75% for CL, 86.56 +/- 5.00% for UL, and 88.91 +/- 5.16% for WV. Significant differences were found between CL and UL and between CL and WV (p < 0.05), but not between UL and WV (p = 0.526). The gutta-percha density of the roots treated with WV and UL increased towards the coronal aspect, but this trend was not noted in the CL group. CONCLUSIONS: WV compaction and UL compaction produced a significantly denser gutta-percha root filling than CL compaction. The density of gutta-percha was observed to increase towards the coronal aspect when the former two techniques were used.

Endodontic microleakage following lateral condensation or vertical condensation technique / 实用口腔医学杂志

0.05) after condensation. The difference of leakage between A and B, B and D groups was significant from 20 and 15 days on. The glucose concentration in group A and B was higher than that in group C and D during the corresponding observation period and using the corresponding sealer materia.AH Plus resulted in less leakage than Pulp Canal Sealer EWT did when using lateral condensation technique and two sealer performed the same when using vertical condensation method.Conclusions:The sealing ability of vertical condensation technique is better than that of lateral.
