Alterations in the stomatognathic system due to amyotrophic lateral sclerosis.

Objectives: To compare the molar bite force, electromyographic activity, chewing efficiency and thickness of the masseter and temporalis muscles in individuals with amyotrophic lateral sclerosis (ALS) and healthy individuals.

Material And Methods: Thirty individuals enrolled in the study were divided into the study group (with ALS, n=15) and control group (healthy individuals, n=15). Data regarding molar bite force (right and left), electromyographic activity (mandibular rest, right and left laterality, protrusion, and maximum voluntary contraction), chewing efficiency (habitual and non-habitual), and masticatory muscle thickness (rest and maximum voluntary contraction) were tabulated and subjected to statistical analysis (Student's t-test, p≤0.

Local administration of Tiludronic Acid downregulates important mediators involved in periodontal tissue destruction in experimental periodontitis in rats.

Objective: The purpose of this study was to evaluate whether local administration of TIL could influence the expression of the inflammatory mediators IL-1β, TNF-α, MMP-8 and COX-2 in rats with experimental periodontitis (EP).

Methods: Twenty-four adult male rats (Rattus norvegicus, albinus, Wistar) were assigned to groups C, EP, EP-TIL (CControl group, EP-Periodontitis groups). On EP groups, a ligature was placed around maxillary 2nd molars on day 1.

Analysis of the stomatognathic system of children according orthodontic treatment needs.

Purpose: The present study evaluated electromyographic activity (EMG), masticatory performance, and tongue strength in children without and with orthodontic treatment needs.

Patients And Methods: A total of 90 children were screened and divided into the following groups: Group I (no treatment needed; mean age: 8.00 ± 0.

Effects of electroacupuncture on experimental periodontitis in rats.

Background: Acupuncture has shown the capability of modulating the immuno-inflammatory response of the host. This study aims to evaluate the effects of electroacupuncture (EA) on ligature-induced periodontitis in rats.

Methods: Thirty-two animals were divided into four groups: 1) control; 2) experimental periodontitis (EP); 3) sham-treated (EP/EA-sham); and 4) treated with EA (EP/EA).

Effects of locally administered tiludronic acid on experimental periodontitis in rats.

Background: It appears there are no studies evaluating the influence of the bisphosphonate tiludronic acid (TIL) on periodontitis. The purpose of this study is to evaluate via microtomographic, histopathologic, histometric, and immunohistochemical analyses the effects of local administration of TIL on ligature-induced periodontitis in rats.

Methods: Forty-eight rats were divided into six groups: C (control), EP (experimental periodontitis), EP-Saline, EP-TIL0.
