A comparative study of effectiveness in plaque removal by Super Floss® and waxed dental floss

The effectiveness of Super Floss and waxed dental floss as proximal surface cleansing agents was compared in 34 subjects. Each subject used 1 agent twice daily for 2 weeks followed by the other agent used with the same frequency and for the same period. The order in which the agents were used was selected at random. Plaque was stained by erythrosin, and a plaque index of Wolffe used. Super Floss was found to be superior to waxed dental floss in removing proximal plaque, but neither was 100% effective. Some plaque was present in 49.9% of the proximal surfaces when Super Floss had been used and on 54.7% when the waxed dental floss had been used. Both agents cleaned distal surfaces better than mesial surfaces, proximal surfaces of anterior teeth more effectively than those of posterior teeth, the coronal half of the proximal surfaces better than the apical half and the facial half more efficiently than the lingual half. No differences were found between maxillary teeth and mandibular teeth. Subjects used more lengths of Super Floss than of waxed dental floss, indicating its relative 'brittleness'. However, the majority of subjects preferred Super Floss, mainly because it was thicker and felt more abrasive.

Efficacy and Safety of Liver Resection in Super Elderly Patients with Hepatocellular Carcinoma

Objective: Liver resection in the super elderly patients remains challenging because of comorbidities and operative tolerability. Methods: In this study, we compared postoperative complications and survival in patients aged ≥85 yr included five patients aged ≥90 yr with those aged 70-79 and 80-84 yr at a single institution. Results: Three hundred sixty-seven patients aged ≥70 yr underwent liver resection and were divided into three groups based on age at operation between 2010 and 2022; (a) 70-79 yr (median of 74 yr, n=245), (b) 80-84 yr (median of 82 yr, n=81), and (c) ≥85 yr (median of 87 yr, n=41). In the ≥85 yr group (90-yr-old group), twenty-five patients (four) had hypertension, fourteen (one) had diabetes mellitus, seven (one) had cardiovascular disease, and five patients (one) had dementia. The rate of comorbidities did not differ significantly among three groups. The rate of postoperative complications (Clavien–Dindo grade 3a≤) was 25% in the 70- to 79-yr-old group, 27% in the 80- to 84-yr-old group, and 17% in the ≥85-yr-old group (20% in the ≥90-yr-old group) (N.S.). The 1- and 5-yr patient survival rates in the ≥85-yr-old group were 90.1% and 48.5% respectively, compared with 86.7% and 60.9% in the 70- to 79-yr-old group and 83.8% and 66.3% in the 80- to 84-yr-old group, respectively (N.S.). Conclusion: Despite the management of comorbidities, liver resection for well-selected super elderly patients, such as those aged ≥85 yr included ≥90yr, has acceptable outcomes. The age of patient is not an absolute contraindication to liver resection.
