JOE MARCH 2011 - Endodontic Outcome Predictors Identified with Periapical Radiographs and Cone-beam Computed Tomography Scans
Endodontic Outcome Predictors Identified with Periapical Radiographs and Cone-beam Computed Tomography Scans
Yu-Hong Liang, DDS,* Gang Li, DDS, PhD,† Paul R. Wesselink, DDS, PhD,‡ and Min-Kai Wu, MSD, PhD‡
Introduction:
The outcome predictors identified with data from periapical radiographs (PA) and cone-beam computed tomography (CBCT) scans might not be the same. This retrospective study evaluated various factors that might affect the outcome of root canal therapy.
Methods:
In total, 115 teeth (143 roots) with vital pulps were endodontically treated and followed up 2 years after treatment. Multivariate logistic regression was per- formed on the data from PA or CBCT to analyze outcome predictors.
Results:
At recall, PA detected periapical lesions in 18 roots (12.6%), as compared with 37 on CBCT images (25.9%). The length and density of root filling determined by PA and CBCT were often different (p < .001). Overall, 20 of the 25 short root fillings (80%) diagnosed by PA appeared as flush fillings on CBCT images. PA revealed 23 root fillings (16.1%) with voids, as compared with 66 on CBCT images (46.2%). When findings from PA were analyzed, density and apical extent of root filling were identified as predictors (p < .05). When findings from CBCT were analyzed, density of root filling and quality of coronal restoration influ- enced the outcome significantly (p # .001), whereas gender, tooth type, root curvature, number of visits, CBCT-determined apical extent of root filling, and use as abutment did not (p > .1).
Conclusions:
Treatment outcome, length and density of root fillings, and outcome predictors as determined with CBCT scans might not be the same as corresponding values deter- mined with PA.

JOE MARCH 2011 - Residual and Antimicrobial Activity of Final Irrigation Protocols on Enterococcus Faecalis Biofilm in Dentin
Residual and Antimicrobial Activity of Final Irrigation
Protocols on Enterococcus Faecalis Biofilm in Dentin

Introduction:
The use of root canal irrigating solutions exerting antimicrobial activity and prolonged residual activity is desirable in order to control dentin infection and delay reinfection of the root canal. The aim of this study was to evaluate the residual antimicrobial activity and the capacity to eradicate Enterococcus faecalis biofilm of different irrigating solutions, alone and in combination, in a dentin-volumetric test.
Methods:
Solutions of 2.5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), 0.2% cetrimide (CTR), 17% ethyl- endiaminetetraacetic (EDTA), 7% maleic acid (MA), and regimens of 2.5% NaOCl followed by 17% EDTA or 7% MA and 0.2% CTR or 2% CHX were used to deter- mine their residual activity by exposing treated dentin blocks to E. faecalis for 24 hours. Antimicrobial activity was assayed on 3-week biofilm formed on dentin blocks. Results of residual activity and antimicrobial activity were respectively expressed as the inhibition percentage of biofilm formation and the kill percentage of biofilm.
Results:
A 2% CHX and 0.2% CTR solution showed 100% biofilm inhibition; 2.5% NaOCl showed the lowest residual activity (18.10%). The kill percentage of 2.5% NaOCl and 0.2% CTR was 100% followed by 7% MA and 2% CHX, whereas 17% EDTA was the least effective (44%). Solutions of 7% MA or 17% EDTA followed by 0.2% CTR or 2% CHX showed 100% residual and antimicrobial activity.
Conclusions:
A 0.2% CTR solution alone and the combinations in which 2% CHX or 0.2% CTR was the final irrigating solution achieved the maximum residual and antimicrobial activity.

Qual motorpara sistema rotatório comprar!?
Boa noite !
Gostaria de saber a opinião dos colegas pois gostaria de investir em um motor para utilizar sistemas rotatórios.
Não sei se é possível falarmos em marcas, mas quais são os recursos que no mínimo ele precisa ter?
Gostaria de poder utilizar diferentes marcas de limas rotatórias e por isso ainda estou em dúvida em que equipamento comprar.
Aguardo opiniões

JOE FEBRUARY 2011 - A High-resolution Computed Tomographic Study of Changes in Root Canal Isthmus Area by Instrumentation and Root Filling
Unni Endal, DDS,* Ya Shen, DDS, PhD,† #Arving Knut, DDS,* Yuan Gao, DDS, PhD,‡ and Markus Haapasalo, DDS, PhD†
Introduction:
The aim of this study was to obtain a three-dimensional analysis of the isthmus area of the mesiobuccal root canal system in mandibular molars using high-resolution micro–computed tomography (m-CT) scanning and to measure the amount of debris and root filling material in the isthmus after instrumenta- tion/irrigation and root filling.
Methods:
Mandibular molars with two separated mesial root canals (10 teeth) were scanned by using the Skyscan 1172 m-CT system (Skyscan, Aartselaar, Belgium) before and after instru- mentation and after filling using the Thermafil root filling technique. An isthmus was defined as the ribbon-shaped or thin connecting structure between two root canals after instrumentation. The characteris- tics of the isthmuses were quantitatively monitored during the whole treatment. The images were segmented and quantified. The surface area of the isthmus, volume of debris after rotary instrumentation, and volume of the filled space in the isthmus after obturation were evaluated.
Results:
Of the seven mesial roots, two had isthmus/anastomoses somewhere along its length in the apical 5 mm, and five had an isthmus that was continuous all the way from the coronal part to the apical part. The average percentage of isthmus surface area and isthmus volume after instrumentation was 21.4% and 9.4% of the whole root canal system, respectively. About 35.2% of the isthmus volume was filled with apparent hard tissue debris after instrumenta- tion/irrigation. The average percentage of volume of filling material in the isthmus areas was significantly lower (57.5%) than in the main root canals (98.5%, p < 0.001).
Conclusions:
A considerable amount of dentin debris is produced and packed into the isthmus area during rotary instrumentation of mesial canals of lower molars despite continuous irrigation during and after instrumentation. The debris may partly prevent penetration of the filling material and sealer into the isthmus area.
