抜髄根管での根尖孔の形成サイズについて。RCT。
(the first apical binding fileより3サイズ大きく拡大するのがよい。それ以上の拡大は利点なし）
根管治療を1回で終了する方法と、2回で終了方法の患者の意見
(治療成績がほとんど同じなので、ほとんどが1回法を選択した）
A prospective study of the extraction and retention incidence of endodontically treated teeth with uncertain prognosis after endodotic referral
(The most frequent reason for the fate of endodontically treated teeth is the loss of dental tissues.)
Comparison of radiographic and survival outcomes of immature teeth treated with either regenerative endodontic or apexification methods
(Revascularization was associated with significantly greater increases in root length and thickness in comparison with calcium hydroxide apexification and MTA apexification as well as excellent overall survival rates)
Effect of preoperative alprazolam on the success of inferior alveolar nerve block for teeth with irreversible pulpitis
(In normal teeth, the rate of success for Inferior alveolar nerve block is 75%-95%.
In case of symptomatic teeth with irreversible pulpitis, 44%-81%.
Preoperative usage of alprazolam did not improve the success rate of inferior alveolar nerve block)
Effect of maintaining apical patency on irrigant penetration onto the apical 2mm of large canals
(It improves the delivery of irrigants into the apical third of large human root canals.)
Effect of calcium hydroxide on cytokine expression in endodontic infections
(The effect of calcium hydroxide are killing vacteria, hard-tissue formation, stopping inflammatory exudates because it impedes the increase of all mediators during the experimental time.)
Effectiveness of endodontic disinfecting solutions against young and old Enterococcus faecalis biofilms in dentin canals
(Fewer bacteria were killed in the 3 week old dentin biofilm than in the 1 day old biofilm.
Effect of canal preparation on filling length in straight root canls obturated with realseal 1 and thermalfil plul
(0.04 standardized taper preparation =STP, varied taper preparation=VTP
Assessment of influence of flexion angles of files in apical stop preparation by using manual and rotary instrumentation techniques
Infection of apical dentin and root-end cavity disinfection
(E.faecalis invaded the entire width of dentin in the apical 3mm. Chlorhexidien was more effective than laser.)
Effect of MTAD as a final rinse on removal of smear layer in ten-minute preparation time
(MTAD, a mixture of a tetracycline isomer, an acid and a detergent, was introduced as a final irrigant.
5.25%NaOCl during instrumentation and 17% EDTA as the final rinse is more effective than 1.3% NaOCl and MTAD as final rinse.)
Comparative evaluation of calcium hypochlorite and sodium hypochlorite on soft-tissue dussolution
(Chlorax(4.65%NaOCl) dissolved the faster than the other solutions)
Depth of penetration of four resin sealers into radicular dentinal tubules:A coronal microscopic study(AH plus,Real Seal,EndoRez,RoekoSeal
Real Seal was best. Real Seal;SybronEnd)
Mechanical behavior of pathfinding endodontic instruments
