DIGITAL DOCUMENTATION AND THE DENTAL OPERATING MICROSCOPE: WHAT YOU SEE IS WHAT YOU GET 

Glenn A. van As

The importance of regular digital photography and documentation in the dental office cannot be understated. The many uses for documentation include publication, diagnosis and treatment planning, dentolegal documentation, forensic documentation, insurance verification, patient education, marketing, and communication with laboratories, dental team members, and colleagues. With the introduction of the dental operating microscope into dental treatment, the ease and scope of documentation have been drastically improved. Images and video taken with the microscope can show details that would not be visible with conventional photography. The aim of this article is to provide an overview of the equipment and techniques available to achieve high-quality digital documentation using an operating microscope.

EEC no JOE - Comparison among Manual Instruments and PathFile and Mtwo Rotary Instruments to Create a Glide Path in the Root Canal Preparation of Curved Canals

Comparison among Manual Instruments and PathFile and Mtwo Rotary Instruments to Create a Glide Path in the Root Canal Preparation of Curved Canals

Introduction: Nickel-titanium rotary instruments reduce procedural errors and the time required to finish root canal preparation. The goal of this study was to evaluate the occurrences of apical transportation and canal aberrations produced with different instruments used to create a glide path in the preparation of curved root canals, namely manual K-files (Dentsply Maillefer, Ballaigues, Switzerland) and PathFile (Dentsply Maille- fer) and Mtwo (Sweden and Martina, Padua, Italy) nickel-titanium rotary files. Methods: The mesial canals of 45 mandibular first and second molars (with curva- ture angles between 25 and 35 ) were selected for this study. The specimens were divided randomly into 3 groups with 15 canals each, and canal preparation was performed by an endodontist using #10-15-20 K-type stainless steel manual files (group M), #13-16-19 PathFile rotary instruments (group PF), and #10-15-20 Mtwo rotary instruments (group MT). The double digital radiograph technique was used, pre- and postinstrumentation, to assess whether apical transportation and/or aberration in root canal morphology occurred. The initial and final images of the central axis of the canals were compared by super- imposition through computerized analysis and with the aid of magnification. The specimens were analyzed by 3 evaluators, whose calibration was checked using the Kendall agreement test. Results: No apical transporta- tion or aberration in root canal morphology occurred in any of the teeth; therefore, no statistical analysis was conducted. Conclusions: Neither the manual instruments nor the PathFile or Mtwo rotary instruments used to create a glide path had any influence on the occurrence of apical transportation or produced any canal aberration.

Motores Elétricos

Bom dia!
Estou para comprar um motor elétrico para instrumentação.
Sö que estou com uma dúvida, será que vale a pena esperar para adquirir um que faça o movimento recíproco tb?

Int Endod J dec 2011 - Diagnostic accuracy of limited-volume cone-beam computed tomography in the detection of periapical bone loss: 360 scans versus 180 scans

Diagnostic accuracy of limited-volume cone-beam computed tomography in the detection of periapical bone loss: 360° scans versus 180° scans 
S. Lennon1, S. Patel1,2, F. Foschi1, R. Wilson3, J. Davies4, F. Mannocci1

Aim: To investigate the effect of reducing limited- volume cone-beam computed tomographs arc of rota- tion from 360° to 180° on the ability to diagnose small, artificially created apical lesions.
Methodology: Small, artificial apical bone lesions were prepared with a bur in the apical region of the distal root of ten mandibular first molars, in human dry mandibles. The jaws were scanned in a fixed position with limited-volume CBCT making a 360° and 180° arc of rotation, before and after each periapical lesion had been created. A 4 · 4 cm field of view was used at 90 kV, with a current of 4 mA. Ten examiners blinded to the scan parameters and con- trols scored the presence/absence of bone lesions.

Intra-examiner reliability was determined after 2weeks, reviewing half the data set. Statistical analyses with paired t-tests determined the diagnostic accuracy of the two modalities (360° vs. 180°) in terms of sensitivity, specificity, receiver operating characteristic area under the curve, positive predictive values and negative predictive values.
Results: The mean values for sensitivity of the 360° and 180° scans were 0.91 and 0.89, respectively; their mean specificities were 0.73. No significant differences were reflected in the statistical analyses.
Conclusions: Both 360° and 180° cone-beam com- puted tomography scans yielded similar accuracy in the detection of artificial bone lesions. The use of 180° scans might be advisable to reduce the radiation dose to the patient in line with the ICRP guidance to use as low a dosage as reasonably achievable.

Keywords: 180°, CBCT, periapical bone loss, ROC, sensitivity, specificity.

JOE dez 2011 - Effect of Canal Length and Curvature on Working Length Alteration with WaveOne Reciprocating Files

Effect of Canal Length and Curvature on Working Length Alteration with WaveOne Reciprocating Files

and Damiano Pasqualini, DDS*

Introduction: This study evaluated the working length (WL) modification after instrumentation with WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) reciprocating files and the incidence of overinstrumenta- tion in relation to the initial WL. Methods: Thirty-two root canals of permanent teeth were used. The angles of curvature of the canals were calculated on digital radio- graphs. The initial WL with K-files was transferred to the matched WaveOne Primary reciprocating files. After glide paths were established with PathFile (Dentsply Maillefer, Ballaigues, Switzerland), canals were shaped with Wave- One Primary referring to the initial WL. The difference between the postinstrumentation canal length and the initial canal length was analyzed by using a fiberoptic inspection microscope. Data were analyzed with a balanced 2-way factorial analysis of variance (P < .05). Results: Referring to the initial WL, 24 of 32 Wave- One Primary files projected beyond the experimental apical foramen (minimum–maximum, 0.14–0.76 mm). A significant decrease in the canal length after instrumen- tation (95% confidence interval ranging from 0.34 mm to 0.26 mm) was detected. The canal curvature signif- icantly influenced the WL variation (F1 = 30.65, P < .001). The interaction between the initial canal length and the canal curvature was statistically significant (F2 = 4.38, P = .014). Conclusions: Checking the WL before prepa- ration of the apical third of the root canal is recommended when using the new WaveOne NiTi single-file system. (J Endod 2011;37:1687–1690)
