Influence of new complete dentures on the touch perception threshold and quality of life of edentulous patients.

Objective: To evaluate the touch perception threshold of the alveolar mucosa and quality of life of edentulous patients before (T0) and 30 days after (T1) the insertion of new complete dentures.

Background: Touch perception is important so that edentulous patients can detect the position of complete dentures in their mouth.

Materials And Methods: This study included 32 complete denture wearers with good oral and systemic health and no temporomandibular disorders for at least 5 years.

Clinical outcomes of digital scans versus conventional impressions for implant-supported fixed complete arch prostheses: A systematic review and meta-analysis.

Statement Of Problem: With the growing use of digital scanning, an evaluation of the clinical impact of digital scans versus conventional impressions in complete arch implant-supported prostheses is needed. However, systematic reviews on this subject are lacking.

Purpose: The purpose of this systematic review was to evaluate the scanning and impression times and the radiographic marginal bone loss over time associated with digital scans and conventional impressions for complete arch implant-supported fixed prostheses.

Incidence of peri-implant disease associated with cement- and screw-retained implant-supported prostheses: A systematic review and meta-analysis.

Statement Of Problem: Implant-supported fixed dental prostheses can be cement- or screw-retained on the implant or abutment, with advantages and disadvantages for each method. Cemented prostheses have been associated with peri-implant disease because cement remnants act as a reservoir for bacteria and hinder biofilm control. However, contrasting evidence has been presented regarding this association based on studies with varying designs, and a systematic review and meta-analysis is required.

Legal concerns in health-related artificial intelligence: a scoping review protocol.

Background: Medical innovations offer tremendous hope. Yet, similar innovations in governance (law, policy, ethics) are likely necessary if society is to realize medical innovations' fruits and avoid their pitfalls. As innovations in artificial intelligence (AI) advance at a rapid pace, scholars across multiple disciplines are articulating concerns in health-related AI that likely require legal responses to ensure the requisite balance.

Effect of Rehabilitation with a New Ocular Prosthesis on Electromyography of the Occipitofrontalis, Temporal, Masseter, and Sternocleidomastoid.

Objectives:  The aim of this study was to verify during facial expressions ("happy," "sad," "fearful," "angry," "surprised," and "disgusted") if: (1) there would be difference in the electromyography (EMG) of the occipitofrontalis, temporal, masseter, and sternocleidomastoid muscles on the normal side (NS) compared with the affected side (AS) (without the use of an ocular prosthesis) in individuals with unilateral absence of the eyeball, and (2) the rehabilitation with a new ocular prosthesis would affect the EMG of the muscles studied on the AS in these individuals.

Materials And Methods:  Thirteen individuals, without temporomandibular disorder, with good health, with unilateral absence of the eyeball (the eye must have been removed by evisceration or enucleation), and users or nonusers of an ocular prosthesis were included. EMG of the occipitofrontalis, temporal, masseter, and sternocleidomastoid muscles was performed during rest and facial expressions ("happy," "sad," "fearful," "angry," "surprised," and "disgusted") before (T0) and 90 days after (T1) rehabilitation with a new ocular prosthesis.

Do Women's Coping Responses to Unwanted Pursuit Behaviors Reduce Future Victimization? A Prospective Exploration.

While some studies have assessed perceptions of the effectiveness of coping responses to unwanted pursuit behavior (UPB) victimization, there is limited research assessing the prospective effectiveness of various coping responses in reducing victimization. The current study assessed the effectiveness of a range of coping responses in reducing UPB victimization over an 8-week timeframe. Undergraduate women who had reported experiencing two or more incidents of UPB following the break-up with a man within the past 3 years ( =181) completed measures on coping responses.

Comparison of different methods for obtaining centric relation: a systematic review.

The objective of this study was to compare techniques of different methods of obtaining centric relation to verify which technique generates the greatest reproducibility of the centric relation. The PubMed/MEDLINE, Cochrane Library, SciELO, Scopus, and Web of Science databases were searched for articles published up to May 15, 2018. The search terms were combinations of "dental centric relation" with each of the following terms (individually): "reproducibility of findings"; "jaw relation record"; "chin point"; "gothic arch"; "bimanual manipulation"; "swallowing"; and "jig.

The Effect of Different Plasma Treatments on the Surface Properties and Bond Strength between Lithium Disilicate and Resin Cement.

Purpose: To evaluate the roughness, surface energy, and the bond strength of lithium disilicate yielded by two different types of nonthermal plasma (NTP), oxygen- or argon-based, compared to the conventional method.

Antimicrobial and protective effects of non-thermal plasma treatments on the performance of a resinous liner.

Objective: Overcoming substantial shortcomings of soft liners as physico-chemical changes and liner-biofilm-related infections remains a challenge in the rehabilitation treatment. In this study, protective non-thermal plasma (NTP) treatments were developed on the soft liner surface to improve its surface and physico-chemical properties and to reduce fungal colonization after biofilm inhibition challenge.

Methods: Resinous liner specimens (Coe-Soft) were prepared and distributed in 3 groups according to the surface treatments: (1) untreated (control); (2) treated with sulfur hexafluoride-based NTP (SF); and (3) treated with hexamethyldisiloxane-based NTP (HMDSO).

Effect of acidic beverages on surface roughness and color stability of artificial teeth and acrylic resin.

Purpose: The aim was to evaluate the effect of four acidic beverages on the roughness (Ra) and color change (ΔE) of two brands of artificial teeth and a heat-polymerized acrylic resin (HPAR) for use in a prosthetic base.

Materials And Methods: All materials were divided into 5 groups, according to the used acidic beverage (artificial saliva - control, red wine, orange juice, coke-based, and lemon juice-based soft drink). The immersion process was divided into two stages: T1 - immersion in the acidic solutions for 10 minutes for 14 days; T2 - after T1, the samples were immersed in grape juice for 14 days.
