121. Efficacy and oral side effects of two highly concentrated tray-based bleaching systems. (Abstract)

colour was evaluated by measuring L*a*b* values generated from standardised digital image analysis with Adobe Photoshop of the facial surfaces of the right central maxillary incisor. Tooth hypersensitivity, with intensity graded from 0 (no hypersensitivity) to 10 (high hypersensitivity), was assessed chair-side using an air syringe. After bleaching therapy, both treatment groups demonstrated significant improvements in tooth colour (p < or = 0.05). A shift towards less yellow (-Deltab*) and brighter

122. Comparison of passive ultrasonic debridement between fluted and nonfluted instruments in root canals. (Abstract)

imported into Adobe Photoshop CS2 (Adobe Systems, San Jose, CA), and percentage of debris remaining was calculated. Analysis of variance and Student Newman-Keuls post hoc tests (p<0.05) showed that when comparing the entire canal, 3 minutes of activation with a file had significantly less debris remaining than 1 minute of activation with a spreader. There was a trend for 1 minute of activation with a file to have less debris than either 3 minutes or 1 minute of activation with a spreader. When

123. The Effect of Cataract Extraction on the Contractility of Ciliary Muscle. (Abstract)

with and without instilling 2% pilocarpine, as well as before and two months after cataract extraction. The mean (+/- standard deviation) age was 65.33 +/- 6.09 years (range, 56 to 75 years). The increase in the axial length of the ciliary body (CBAXL) was used as a surrogate indicator of the centripetal ciliary muscle contraction during accommodation. Images of the ciliary body were compared visually using Adobe Photoshop 7.0 (Adobe Systems Inc., San Jose, California, USA).The CBAXL value with and without

124. Clavicular anatomy and the applicability of precontoured plates. Full Text available with Trip Pro

and magnitude of the superior clavicular bow were determined with use of a digitizer and modeling software. Axial radiographs were made of each clavicle and the precontoured Acumed Locking Clavicle Plate, which is designed to be applied superiorly. With use of Adobe Photoshop technology, the plates were freely translated and rotated along each clavicle to determine the quality of fit and the location of the "best fit."The location of the maximum superior bow was lateral, with a mean distance of 37.2

125. Canal transportation after root canal instrumentation: a comparative study with computed tomography. (Abstract)

by an electric engine; Group 3, ProTaper NiTi rotary system powered by an electric engine. To compare the canal transportation produced by the different techniques, preinstrumentation and postinstrumentation 3-dimensional CT images were obtained from root cross-sections of the region located 3 mm short of the apical foramen of each root canal. The CT scans were exported to Adobe Photoshop software, and the initial and final images were superimposed to detect the root canal wall differences between them

computer by a scanner and then magnified 400 times by Adobe Photoshop software (Adobe Systems, Mountain View, CA). P wave dispersion, which is also defined as the difference between the maximum P wave duration and the minimum P wave duration, was also calculated.After a 12-week weight loss program, BMI (p < 0.001), maximum P wave duration (p < 0.001), and P wave dispersion (p < 0.001) significantly decreased. The mean percentage of weight loss was 13% (10% to 20.3%). The decrease in the level of P wave

129. Gray-scale median of the atherosclerotic plaque can predict success of lumen re-entry during subintimal femoral-popliteal angioplasty. Full Text available with Trip Pro

subintimal angioplasties of the femoral-popliteal segment. Preprocedural B-mode DUS images of the plaque at the most distal occlusion segment were digitalized and normalized using Photoshop (Adobe, San Jose, Calif) software and standard criteria (gray level, 0 to 5 for lumen blood and 185 to 190 for the adventitia on a linear scale of 0 to 255). Overall GSM of the plaque segment about 2 cm long, immediately before the planned re-entry point to the true arterial lumen, was used for retrospective

131. The clinical significance of adenoid-choanae area ratio in children with adenoid hypertrophy. (Abstract)

treatment other than the above-mentioned procedures in the same period. We used 0 degrees telescope to take pictures of the nasopharynx under general anesthesia preoperatively. The pictures were transformed digitally. The A/C ratio was calculated by the program we developed after these pictures were processed by the Photoshop 6.0 (Adobe, USA) software.The A/C ratio in adenoid hypertrophy group (0.863+/-0.0983) is significantly higher (p<0.001) than that of control group (0.445+/-0.1431).

132. Measuring nasal tip and lobule width; effect of transdomal and lateral crura suturing. (Abstract)

rhinoplasty patients were analysed. Transdomal sutures and lateral crura sutures were used in 29 and 28 patients, respectively. TI and LI were determined with digital imaging software (Adobe Photoshop) pre- and postoperatively.Average (SD) preoperative LI changed from 0.74 (0.07) to 0.71 (0.06) postoperatively with the lateral crura suturing technique (p = 0.045). We were not able to measure an effect in TI with the transdomal suturing technique.Detailed postoperative analysis with digital imaging

133. In vitro radiographic determination of distances from working length files to root ends comparing Kodak RVG 6000, Schick CDR, and Kodak insight film. (Abstract)

to digitized Kodak film. Standardized images were taken of files placed 0.5 to 1.5 mm short of true radiographic lengths. Images were imported into Adobe PhotoShop 7.0, thereby blinding observers who measured distances from files to root apices and assessed images for clarity (acceptability). Repeated measures ANOVA and Tukey-Kramer post hoc tests demonstrated that Kodak RVG 6000 images with enhanced contrast produced significantly less measurement error than unenhanced contrast Schick CDR images (p < 0.05

134. Anterior tibial subluxation in anterior cruciate ligament-deficient knees: quantification using magnetic resonance imaging. (Abstract)

deficiency and no history of injury in the contralateral knee were studied. We used thick-sliced T1-weighted sagittal MRI to quantify ATS at full extension. To measure ATS, MRIs were loaded into a personal computer, and the contour of the unaffected knee was compared with the affected knee using Photoshop software (Adobe, San Jose, CA). Anterior instability was measured using a KT-1000 arthrometer (MedMetric, Inc, San Diego, CA).The extent of ATS in 96 ACL-deficient knees was 2.1 +/- 1.3 mm (mean +/- SD

at baseline, weeks 1, 2, 4, 6 and month 3 by using optical coherence tomography (Stratus OC, Carl Zeiss Meditec, Dublin, California, USA). Changes in maximum PED height and greatest linear diameter (GLD) were planimetrically analysed by using Adobe Photoshop CS and correlated with retinal morphological changes and changes in BCVA.Systemic bevacizumab therapy was well tolerated. Mean maximum PED height decreased significantly by 21% as early as 1 week (-96 microm (SD 48.8), p<0.01). At 3 months follow-up

image./This report outlines an alternative shading correction method that is based upon the intrinsic properties of the image, which are revealed through Gaussian smoothing. The technique can be implemented within Adobe Photoshop or other graphics editing software and works well with both haematoxylin and eosin and immunohistochemical images.This technique provides an effective means of optimising digital microscopy image appearances for printing, image analysis, or telepathology.
