Stomathognatic system function in indigenous people from Brazilian Xingu villages: An electromyographic analysis.

The maintenance of postural balance can be influenced by the lifestyle of a population. This study aimed to determine the electromyographic activity of the masseter and temporalis muscles during mandibular tasks and habitual and non-habitual chewing in indigenous individuals to reveal the differences among white Brazilian individuals. Sixty Brazilians (18 and 28 years) were divided into two groups: 30 Xingu indigenous individuals and 30 white Brazilian individuals, with 20 men and 10 women in each group.

Alterations in masticatory cycle efficiency and bite force in individuals with periodontitis.

Objectives: The objective of this research was to evaluate the effect of periodontitis on masticatory cycle efficiency and maximum molar bite force.

Methods: Twenty-four individuals were divided into two groups: With periodontitis (Group I; mean age ± standard deviation (SD), 51.3 ± 2.

Does a mandibular RDP and new maxillary CD improve masticatory efficiency and quality of life in patients with a mandibular Kennedy class I arch?

Objectives: To evaluate the change in masticatory efficiency and quality of life of patients treated with mandibular Kennedy class I removable partial dentures (RPDs) and maxillary complete dentures at the Department of Dentistry of the Federal University of Rio Grande do Norte.

Materials And Methods: A total of 33 Kennedy class I patients were rehabilitated with maxillary complete dentures, and mandibular RPDs were selected for this non-randomized prospective intervention study. The patients had a mean age of 59.

Reproducibility, Reliability, and Validity of Fuchsin-Based Beads for the Evaluation of Masticatory Performance.

Purpose: Rehabilitation of masticatory function is inherent to prosthodontics; however, despite the various techniques for evaluating oral comminution, the methodological suitability of these has not been completely studied. The aim of this study was to determine the reproducibility, reliability, and validity of a test food based on fuchsin beads for masticatory function assessment.

Materials And Methods: Masticatory performance was evaluated in 20 dentate subjects (mean age, 23.

Comparison of dynamic electromyographic analysis of masticatory capsules with materials of different textures.

Objectives: The aim of this study was to compare the mastication electromyographic indexes of capsules used for the masticatory efficiency evaluation "ME-mastig" and of materials of different textures (gum, raisins, and peanuts).

Methods: Thirty young, healthy, adult subjects, with an average age of 23.46 years old, with no symptoms of temporomandibular dysfunction (TMD), confirmed by the clinical exam, RDC/TMD, and the static test of electromyography (EMG) were chosen.

The influence of mandibular implant-retained overdentures in masticatory efficiency.

Objective: To evaluate the masticatory efficiency of patients rehabilitated with conventional dentures (CDs) or implant-retained mandibular overdentures.

Background: Despite the evident benefits of implants on mastication as assessed by subjective patient-based outcomes, the extent of implant overdenture treatment effect on food comminution is not well established.

Materials And Methods: A randomised clinical trial was carried out with 29 completely edentulous patients divided into two groups.

[The oral health care model in Middle and Low Xingu: partnerships, processes, and perspectives].

The purpose of this article is to present the actions developed to create the health care model at the Special Indigenous District - Xingu (DSEI-Xingu); particularly regarding oral health. An effective partnership established among the following institutions University Federal of State São Paulo, University of São Paulo at Ribeirão Preto College of Dentistry and Colgate, allowed the development of social health praxis at Middle and Low Xingu. The "Social Space" DSEI, which throughout the history, communities have developed and, through the social process of production, create differentiated accesses to consumer goods, is the basis for organizing health care services for the indigenous population.

Masticatory efficiency in denture wearers with bilateral balanced occlusion and canine guidance.

The maintenance of masticatory function is especially important for patients wearing complete dentures due to their limitations. Thus, the bilateral balanced occlusal concept is used to achieve greater masticatory efficiency. However, a critical review of the literature reveals that there is not sufficient scientific evidence to support bilateral balanced occlusion as the most appropriate occlusal concept in complete dentures.

Reliability of masticatory efficiency with beads and correlation with the muscle activity.

Background: the use of the colorimetric method with beads to evaluate mastigatory efficiency may be promising, however no report is found about its reliability.

Aim: to investigate the reliability of the beads to test masticatory efficiency and its correlation with the electromyographic activities of the anterior temporal and masseter muscles.

Methods: participants of this study were nineteen young adults, nine males and ten females, aged eighteen to twenty-eight years, with full dentition, Angle class I, with no history of temporomandibular disorder, neurological or cognitive deficit, previous or current tumors or traumas in the head and neck region, and orthodontic treatment or orofacial myofunctional therapy.

Development of a colorimetric system for evaluation of the masticatory efficiency.

The stomatognathic system is responsible for complex vital functions such as chewing, deglutition, respiration and phonation. Food breakdown is one of the masticatory functions, which enables reducing the attrition against the oral soft tissues and increasing the surface contact of food particles with digestive secretions, thus leading to satisfactory and rapid physiological processes. The methods of evaluation the masticatory efficiency are restricted to electromyography, sieving and clinical observation.

Comparison of different methods for the occlusal dentine caries diagnosis.

The aim of this study was to compare the effectiveness of in-vitro methods for the occlusal dentine caries diagnosis. Thirty-eight sites were evaluated on third molars without macroscopic carious cavitation in adult individuals from the city of Barretos (SP), Brazil. Visual inspection (VI), endoscopic evaluation (AcuCam), visual inspection and blunt-tipped exploratory probes (Tactile), conventional bite-wing radiographs (CR), direct bite-wing digital radiograph (DR), and direct digital radiograph with contrast and brightness controled (DRbc) were used by five observers.
