This study assessed the safety and efficacy of three different doses BoNT-A for persistent myofascial pain (MFP). One hundred female subjects were randomly assigned into five groups (n = 20): oral appliance (OA), saline solution (SS) with doses. Pain intensity pressure threshold evaluated up to 24 weeks after treatment. Adverse effects related muscle contraction, masticatory performance, thickness mandibular bone volume also assessed. Changes over time compared within between groups. The...

Masticatory function evaluated by quantifying occlusal pairs determining efficiency swallowing threshold with sieving method. During test, chewing rate registered. ability also a 5‐point...

This study compared the microleakage of class V restorations bonded with various one-step self-etching adhesives. Seventy resin-based composite were prepared on buccal and lingual surfaces 35 premolars, by using: Clearfil S3 Bond, G-Bond, iBond, One Coat 7.0, OptiBond All-In-One, or Xeno IV. The Adper Single Bond etch-and-rinse two-step adhesive was employed as a control. Specimens thermocycled for 500 cycles in separate water baths at 5°C 55°C loaded under 40 to 70 N 50,000 cycles. Marginal...

The influence of mandibular movement timing on food breakdown remains unclear. authors, therefore, sought to relate chewing rate with masticatory performance. Chewing rate, defined as the number cycles habitually achieved per minute, was measured in 55 healthy dentulous subjects (age, 22.2 +/- 5.0 years). Subjects were grouped according obtained values (cycles/minute): slower: < 70; middle: 70-90; and faster: > 90. Masticatory performance determined through sieve method, estimated comminuted...

To assess the histopathological changes of rat palatal mucosa exposed to soft reline materials.Forty-five adult female Wistar rats with controlled living conditions and fed ad libitum were employed. Palatal appliances heat-polymerized acrylic resin Lucitone 550 manufactured worn by forty animals during 14 days. Five did not use (G1) used control appliance influence. One experimental group (n = 10) without any relining material (G2) effect. Three groups received following materials below...

The present study aimed to assess the effectiveness and functional adverse effects of a single multiple injections botulinum toxin A (BoNT-A) for masseter hypertrophy (MH). Twenty-six women complaining about lower third facial enlargement due MH, received 75 U BoNT-A (abobotulinum toxin) in each muscles. After 3 months, patients were randomly assigned receive second treatment session Saline Solution: (G1; n = 11) or BoNT-A: (G2; 12). Muscle thickness (ultrasound), electrical activity...

The aim of this study was to evaluate the reproducibility condensation silicone Optosil Comfort® as an artificial test food for masticatory performance evaluation. Twenty dentate subjects with mean age 23.3±0.7 years were selected. Masticatory evaluated using simple (MPI), double (IME) and multiple sieve methods. Trials carried out five times by three examiners: first, once second third examiners. Friedman's used find differences among time trials. Reproducibility determined intra-class...

Abstract Purpose Temporomandibular disorders (TMD) are recognized as one of the most controversial topics in dentistry, despite fact that both basic science and clinical researchers have currently reached some degree consensus. This study aimed to conduct a questionnaire‐based survey about management TMD patients by general dental practitioners (GDPs). Materials Methods One hundred fifty‐one GDPs with private practice city southern Brazil were included, independent school origin, gender,...

Rehabilitation of masticatory function is inherent to prosthodontics; however, despite the various techniques for evaluating oral comminution, methodological suitability these has not been completely studied. The aim this study was determine reproducibility, reliability, and validity a test food based on fuchsin beads assessment.Masticatory performance evaluated in 20 dentate subjects (mean age, 23.3 years) using two kinds foods methods: ultraviolet-visible spectrophotometry, silicone cubes...
