Fractal analysis of dental periapical radiographs: A revised image processing method.

Objective: To assess trabecular bone structure as calculated with fractal analysis by 2 binarization processes: White and Rudolph's original method (WR.o) and a revised version (WR.r).

Narrow-Diameter Implants for Partial Fixed and Removable Prostheses: A Systematic Review and Meta-Analysis.

Purpose: To answer the following focus question: Are narrow-diameter implants feasible to support fixed dental prostheses (FDPs) and partial removable dental prostheses (PRDPs)?

Materials And Methods: This review followed the PRISMA statement and was registered in the PROSPERO database (CRD42020153729). Six databases and the gray literature were searched through October 2021 without language, publication time, or follow-up restrictions. The main outcomes were survival, success, and marginal bone loss (MBL).

Action of disinfectant solutions on adaptive capacity and virulence factors of the Candida spp. biofilms formed on acrylic resin.

Background: Understanding the behavior of Candida spp. when exposed to denture disinfectants is essential to optimize their effectiveness. Changes in the virulence factors may cause increased resistance of Candida spp.

Failures in Single Extra-Short Implants (≤ 6 mm): A Systematic Review and Meta-analysis.

Purpose: The aim of this systematic review with meta-analysis was to compare the survival rate of single crowns supported by extra-short implants (≤ 6 mm) to those supported by conventional implants, with or without previous maxillary sinus augmentation. The proportion of failures was described according to the type of complication and follow-up periods.

Materials And Methods: Randomized and prospective clinical trials were selected from six databases and gray literature.

The effects of three disinfection protocols on Candida spp., denture stomatitis, and biofilm: A parallel group randomized controlled trial.

Statement Of Problem: Antifungals are used to treat Candida infections. However, because of increased antifungal resistance and the length of antifungal therapy, Candida spp. infections can be prevented using the prosthesis hygiene method.

Antibiofilm Activity of an Experimental Ricinus Communis Dentifrice on Soft Denture Liners.

The disadvantage of liners materials is the difficulty of biofilm control. It was compared an experimental dentifrice contained Ricinus communis, with commercials dentifrices as antibiofilm activity against microorganisms on denture liner. Six hundred specimens were distributed in 5 groups (n=18/ microorganism): water; experimental dentifrice; specific dentifrice for denture and two conventional dentifrices against C.

In Vitro Evaluation of Resilient Liner after Brushing with Conventional and Experimental Ricinus communis-Based Dentifrices.

Purpose: To evaluate the effect of experimental (Ricinus communis) and commercial dentifrices used for denture cleaning on abrasiveness (gravimetric method; roughness), hardness, and color stability of a resilient relining material.

Materials And Methods: Sixty circular (15 × 3 mm) specimens were distributed into four groups: C (control; brushing with water); CO (brushing with Colgate - for natural teeth); CB (brushing with Corega Brite - for complete dentures); RC (brushing with experimental dentifrice). Brushing was performed in a toothbrushing machine with a soft brush and a dentifrice suspension for 50 minutes, calculated to correspond to 1 year of regular brushing.

Clinical trial for evaluation of Ricinus communis and sodium hypochlorite as denture cleanser.

Objective: This study evaluated Ricinus communis and sodium hypochlorite solutions in terms of biofilm removal ability, remission of candidiasis, antimicrobial activity, and participant satisfaction.

Material And Methods: It was conducted a controlled clinical trial, randomized, double-blind, and crossover. Sixty-four denture wearers with (n=24) and without candidiasis (n=40) were instructed to brush (3 times/day) and immerse their dentures (20 min/day) in different storage solutions (S1 / S2: 0.

Effect of sodium hypochlorite and Ricinus communis solutions on control of denture biofilm: A randomized crossover clinical trial.

Statement Of Problem: The prevalence of complete edentulism remains high in the elderly, and previous data have shown that poor denture hygiene is common among patients with edentulism.

Purpose: The purpose of this randomized crossover trial was to evaluate the efficacy of denture cleansers in terms of biofilm removal, antimicrobial action, and the remission of denture stomatitis.

Material And Methods: Fifty denture wearers with denture stomatitis were instructed to brush their dentures (brush and soap) and to soak them (20 minutes/14 days) in 4 solutions, as follows: C (control), 0.
