Recent practice guidelines recommend venous thromboembolism prophylaxis for 28 days after cancer surgery. We sought to characterize and compare awareness, agreement, adoption, and adherence to these guidelines among surgeons.

We electronically surveyed Canadian hepatobiliary surgeons registered with the Canadian Hepatopancreatobiliary Association, general and colorectal surgeons registered with the College of Physicians and Surgeons of Ontario and the Canadian Society of Colorectal Surgeons who provide colorectal cancer care with a pilot-tested questionnaire. Attitudes to relevant guideline recommendations and perceived barriers to postdischarge venous thromboembolism prophylaxis were assessed on a 5-point Likert scale.

There were 128 responses (response rate 60%, 128 of 213), including 60 general/colorectal and 68 hepatobiliary surgeons. Most surgeons were aware (122 of 128, 95%), agreed (101 of 122, 83%), adopted (78 of 101, 77%), and adhered (74 of 78, 95%) with guidelines. Preexisting venous thromboremain apprehensive about postdischarge venous thromboembolism prophylaxis cite poor evidence and cost of the medication as the major barriers. Adherence was higher among hepatobiliary surgeons and at hospitals with existing venous thromboembolism-prophylaxis programs.
The accuracy of digital scanning for complete dental arch and implant-supported complete-arch restorations has been reported. However, research addressing the accuracy of digital scanning methods for complete-arch tooth preparation is lacking.

The purpose of this invitro study was to compare the accuracy of intraoral scanning, impression scanning, and cast scanning for complete-arch preparation.

Maxillary and mandibular jaw typodonts with 28 teeth prepared for complete crowns were used as reference casts and digitized as reference data sets with a desktop scanner. Three digital scanning methods were applied. First, the reference casts were each scanned 10 times with an intraoral scanner to generate the intraoral scanning group data sets. Second, the reference casts were each captured 10 times by using polyvinyl siloxane impression material, and the impressions were scanned with a desktop scanner to generate the impression scanning group data sets. Third, the impressions obtained in the impression scannial symmetrical displacement in the intraoral scanning group relative to the reference data sets and within-group unilateral distal-end distortion. Irregular arch deformations were noted in the impression scanning group, and buccal and occlusal expansion occurred in the anterior-posterior direction in the cast scanning group. Pooled data for anterior teeth indicated that the trueness was lowest in the intraoral scanning group; however, that for the maxillary anterior teeth did not differ, while that for the mandibular anterior teeth differed significantly among groups (P<.05). For the posterior teeth, deviation was the lowest in the impression scanning group, and significant differences were noted in both arches among the 3 groups (P<.05).

Of the methods tested, impression scanning was the most accurate for the creation of a digital cast of a complete prepared arch.

Denture stomatitis affects complete denture wearers and is frequently treated with antifungals drugs, as well as treating the denture with sodium hypochlorite. Whether the limitations of these treatments can be overcome with local hygiene protocols that do not damage the denture materials or adversely affect the patient is unclear.

The purpose of this randomized controlled trial was to evaluate the effect of denture hygiene protocols on complete denture wearers with denture stomatitis.

For this randomized, double-blind controlled clinical trial, 108 participants were assigned to parallel groups 0.25% sodium hypochlorite (positive control) 0.15% Triclosan, denture cleaning tablets, or denture cleaning tablets plus gingival cleaning tablets. The participants were instructed to brush the dentures and the palate and immerse the denture in the solutions. The outcomes of denture stomatitis remission, biofilm removal, decrease of microbial load (colony-forming units), and odor level of the mouth and denture wenture cleaning tablets showed a significant reduction in Staphylococcus spp.; all protocols had similar effects. Only the S.mutans count of the palate decreased after 10 days. The odor level of the mouth and the denture was not significantly different (P=.778).

The evaluated protocols can be recommended for the hygiene of complete dentures, since they were effective for all the variables studied.

The Kois Dento-Facial Analyzer (KDFA) is used by clinicians to mount maxillary casts and to evaluate and treat patients. Almorexant Limited information is available for understanding whether the KDFA should be considered as an alternative to an arbitrary facebow.

The purpose of this clinical study was to evaluate and compare maxillary casts mounted by using the KDFA with casts mounted by using the Panadent Pana-Mount Facebow (PMF) and a kinematic axis (KA) facebow.

Fifteen participants were enrolled in the study. Three maxillary impressions were made of each study participant. One cast from each study participant was mounted on an articulator by means of the KDFA, PMF, and KA. A standardized photograph of each mounting was made, and the condylar center-incisor distance and the occlusal and incisal plane angles were measured. A randomized complete block design analysis of variance (RCBD) (α=.05) and post hoc tests (Tukey-Kramer HSD) were used to evaluate the occlusal and incisal plane angles and the condylar center-incisor distance.

Compared with the occlusal plane angle (OPA), the KDFA mounted the maxillary cast at an angle that was statistically lower than those of PMF and KA (P<.001). The KDFA and the PMF condylar center-incisor distances were both significantly greater than that of KA (P=.01). No differences were found between the incisal plane angle (IPA) on maxillary casts mounted with the KDFA, KA, or PMF (P=.16).

The KDFA and PMF mounted the maxillary casts in a position that was farther from the axis when compared with the KA mounted casts. The KDFA resulted in a lower articulator OPA compared with both PMF and KA. No difference was found between the IPAs of the KDFA, PMF, and KA.
