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.

All on Four® fixed implant support rehabilitation: a masticatory function study.

Background: Fixed implant-supported prostheses according to All-on-Four® (Nobel Biocare, Goteborg, Sweden) principles have become an accepted treatment modality in totally edentulous patients, whereas the functional effect of this therapy is limited.

Purpose: The purpose of this study was to evaluate the muscular function of patients totally rehabilitated with All-on-Four.

Materials And Methods: This study evaluated 63 patients.

Evaluation of molar and incisor bite force in indigenous compared with white population in Brazil.

The purpose of this study was to determine maximum bite force in molar and incisor regions in young Brazilian indigenous individuals, who have had a natural diet since birth, and compare the sample with white Brazilian individuals. To do this, individuals were paired one-to-one (same weight, height, and Class I facial pattern). A secondary purpose was to elucidate the relation between bite force and gender in both populations.

The effect of age on the function of the masticatory system--an electromyographical analysis.

Background: Old age is the last stage of human life and, unfortunately, the ageing rhythm of the oral cavity and masticatory system seems to be rather accelerated. Hence, there is a reduction in the amount of food ingested, establishing the imbalance of nutritional phenomena.

Objective: To assure a better quality of life for the elderly, it is necessary to understand their masticatory system.

Electromyographic analysis of the orbicularis oris muscle in oralized deaf individuals.

Electromyography has been used to evaluate the performance of the peribuccal musculature in mastication, swallowing and speech, and is an important tool for analysis of physiopathological changes affecting this musculature. Many investigations have been conducted in patients with auditory and speech deficiencies, but none has evaluated the musculature responsible for the speech. This study compared the electromyographic measurements of the superior and inferior fascicles of the orbicularis oris muscle in patients with profound bilateral neurosensorial hearing deficiency (deafness) and healthy volunteers.

Autogenous tooth fragment reattachment--association of periodontal surgery and endodontic and restorative procedures: a case report.

The occurrence of dental traumas in adult patients is on the rise, according to the literature, and require correct and adequate treatment specific to each fracture in order to preserve the remaining tooth. In this article, two different fracture cases are reported. Based upon these cases, it may be concluded that there are situations that require the clinician to have a multidisciplinary vision of the different dental specializations in order to effectively treat the patient.
