“…Many obturation techniques have been developed to obtain a complete root canal filling. For comparative purposes, the composition of the root filling techniques have been evaluated by achieving the percentage area of gutta-percha, sealer and voids (11,12). In the present study, lateral incisors were used in attempt to avoid the presence of isthmus or flattening areas, commonly found in molars and mandibular incisors (13).…”

The aim of this study was to determine the percentage of voids, gutta-percha and root canal sealer using 4 different filling techniques. Fifty-two extracted maxillary lateral incisors were prepared using the crown-down pressureless technique. The teeth were randomly divided in 4 groups (n=13): Lateral compaction (LC), Tagger's hybrid (TH), MicroSeal (MS) and GuttaFlow (GF) techniques. Horizontal cross-sections were made at the 2, 10 and 15 mm levels from the apex. Digital images of the root canal areas were acquired using a stereomicroscope and examined using the Image Tool 3.0 software. Statistical analysis was performed using the Kruskal-Wallis test (α=0.05). In general, a significant decrease in the gutta-percha filled area and increase of sealer area were observed at the apical level for all the evaluated techniques (p<0.05). With regard to the presence of voids, no significant difference was found. MS and TH techniques showed a larger gutta-percha filled area than LC and GF techniques at the coronal and middle third level (p<0.05). From the results of the present study, it may be concluded that the gutta-percha filled area of fillings decrease at the apical level, regardless of the filling technique used.

“…Better results in the gutta-percha filled area at the apical level could be expected by increasing the apical diameter of root canal preparation (12,16). At the coronal and middle level of the canal, the adaptation of the filling material was found to be easier because of the ability of finger spreader and compactors to access this area.…”

“…Recent scientific evidence shows that larger apical preparations presents several advantages, such as increasing the irrigant solution volume at the apical third of the root canal system 13,18 , more debris elimination and a reduction of non-instrumented areas in the root canals 19,20 . Moreover, the increase in apical diameter is related to a reduction in bacterial population and improved canal filling procedures [11][12][13] . However, it is certainly not an easy clinical task to achieve a larger apical diameter, especially in curved, narrow and long canals.…”

“…Furthermore, TFA files have three unique design features: a special surface conditioning, an R-phase heat treatment and a twisting of the metal 9,10 . Recent scientific evidence shows that larger apical canal preparations promote more effective irrigation into the apical area, improved infection control and better quality of the root fillings [11][12][13] . However, limited data regarding canal transportation after larger apical preparations using these new NiTi systems are available.…”

[TFA]) systems in maintaining the original canal profile in straight and curved parts after apical preparations up to size 40. Methods: Resin blocks with simulated curved canals were randomly assigned to five groups: PTU, PTN, R, WO and TFA. Images were captured from each block before and after canal preparation (n=10). Assessment of canal transportation was obtained for the straight and curved parts of the canal. ANOVA followed by Tukey's test was used (α = 5%). Results: Transportation values were increased at the curved part (P = .00). For both canal levels, TFA system induced the lowest mean of canal transportation followed by PTN, R, WO and PTU systems. At the straight portion, transportation for R and TFA systems were similar (P > .05), and these values were significantly lower than for WO, PTN and PTU (P = .00). At the curved portion, TFA resulted in less canal transportation, followed by PTN, R, WO and PTU systems (P = .00). Conclusions: TFA system produced less canal transportation than other systems tested during large apical preparations.

“…Corticosteroids are potent anti-inflammatory drugs that suppress inflammatory phenomena as pain and edema 7 . Thus, the use of this drug is an effective supplement to reduce of these symptons after endodontic treatment8, and its use in the treatment and prevention of pain and endodontic post-treatment swelling has been shown to be effective and safe [8][9][10][11][12][13][14][15][16] . Among the corticosteroids, betamethasone has fast, potent and long-lasting action, a dose of 0.5 mg being necessary for an equivalent 20 mg of endogenous hydrocortisone 17 , without causing the undesirable mineralocorticoid activity of sodium retention 11 and it is even more effective than dexamethasone, equivalent dose of which is 0.75 mg 17 .…”

Periapical injection of betamethasone to control postoperative pain in emergency endodontic care - a randomized double blind clinical trial

2017

Aim: the objective of this study was to evaluate the effect of betamethasone in the control of postoperative pain in patients undergoing endodontic treatment. Methods: patients of both genders (n = 120), after being submitted to emergency endodontic treatment, received a single dose of betamethasone solution (0.05 mg / body weight) or sterile saline solution intramucosally, in the periapical region of the treated tooth. The study evaluated the intensity of pain experienced by the patient and the number of analgesics consumed during periods of 4, 24 and 48 hours after endodontic treatment. To compare the level of pain among the groups and the use of analgesics the Fisher's Exact Test was used, adopting a significance level of 95%. Results: patients who received betamethasone felt less pain in 4 hours (p = 0.0177) and 24 hours (p = 0.0012) compared to those who received the placebo. Conclusions: betamethasone at a dose of 0.05 mg / body weight administered in the periapical region is a advantageous protocol due to its effectiveness, and also because of the comfort it provides to patients in the prevention or control of inflammatory pain in endodontics.
