Studies have explored occlusal marking interpretation, repeatability and accuracy. But, when an occlusion detection product is interposed between teeth, direct tooth-tooth occlusal contact relationships are replaced by tooth-material-tooth structures. Thus, the marks cannot reflect the original contacts. This has been shown for single tooth pair contacts. The purpose of this laboratory study was to similarly examine full dentitions. A dentiform was set into Class I centric occlusion with the mandible supported by a load cell...

BACKGROUND: Tongue thrust which is an oral reflex associated with sucking behaviour may cause problems in swallowing, speech, orofacial development, and also drooling. OBJECTIVE: We aimed to examine the effect of Functional Chewing Training(FuCT) on tongue thrust and drooling in children with cerebral palsy (CP). METHODS: The study included 32 children with a mean age of 58.25±9.58 months who had tongue thrust. Children were divided into two groups: The FuCT group and control group receiving classical oral motor exercises...

There is limited information of the normal function of the human medial pterygoid muscle (MPt). The aims were to determine whether (a) the MPt is active throughout horizontal jaw movements with the teeth apart and (b) whether single motor units (SMUs) are active during horizontal and opening - closing jaw movements. Intramuscular electrodes were placed in the right MPt of 18 participants who performed 5 teeth-apart tasks: 1) postural position, 2) ipsilateral (i.e. right) jaw movement, 3) contralateral movement, 4) protrusive movement, 5) opening-closing movement...

Prosthodontic treatment success depends on patients' ability to adapt to an altered oral environment containing removable prostheses. We investigated adaptive chewing-related brain activity changes in response to a new oral environment. Twenty-eight fully dentate subjects (mean age: 28.6 years) wore experimental denture-base palatal plates (3-mm thick), for 7 days. We measured food mixing ability and cycle time, and assessed brain activity by functional magnetic resonance imaging during chewing at pre-insertion (Day 0), and immediately (Day 1), 3 days (Day 3), and 7 days (Day 7) after insertion...

BACKGROUND: Assessment of swallowing musculature using motor evoked potentials (MEPs) can be used to evaluate neural pathways. However, recording of the swallowing musculature is often invasive, uncomfortable and unrealistic in normal clinical practise. OBJECTIVE: To investigate the possibility of using the suprahyoid muscle complex (SMC) using surface electromyography (sEMG) to assess changes to neural pathways by determining the reliability of measurements in healthy participants over days...

Anterior repositioning splints (ARS) are used primarily for the management of temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDwR). However, the exact physiological effects of ARS are still unclear. This study investigated the short and long-term effects of ARS on disc and condyle angles/positions by metric analysis. Twenty-two subjects diagnosed with ADDwR were recruited. Maxillary full-coverage ARS were fabricated, and MRI of TMJs was obtained before splint treatment, immediate post-insertion and 6 months after splint treatment...

Oral food perception depends on somato-sensory information that includes taste and can be modified by oral components and/or functions such as mastication. The purpose of this study is to describe the interplay between oral health, mastication and taste. A review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was conducted on 615 publications found by both pubmed and backward research. Thirty-one studies have been included. The results showed that the decline in taste ability observed during the healthy aging process could be potentiated by the deterioration of oral health and poor oral hygiene...

There is widespread consensus that the neutral zone (NZ) concept contributes to improved stability for mandibular complete dentures (CDs). However, little is known about its impact on oral health-related quality of life (OHRQoL) of edentulous patients compared to conventionally (CV) manufactured dentures. In this prospective crossover trial, performed at the Oral Health Centre of the University of the Western Cape, CV and NZ mandibular dentures were made for each patient. Scores from the 20-item oral health impact profile (OHIP-20) for both types of dentures were compared with pre-treatment scores using paired t-tests...

To investigate effects of transcranial direct current stimulation (tDCS) on neuroplasticity in corticomotor pathways related to tongue muscles evoked by a training task using the Tongue Drive System (TDS). Using a cross-over design, 13 healthy participants completed two sessions of tDCS while performing 30 min of TDS training. Sessions were spaced at least 2 weeks apart and participants randomly received anodal and sham tDCS stimulation in the first session and the other condition in the second session. Single and paired pulse transcranial magnetic stimulation was used to elicit motor evoked potentials (MEPs) of the tongue at three time-points; before, immediately after and 30 min after training...

BACKGROUND: Masticatory muscle-pain patients often complain about sensorimotor changes, but the effects of pain on the psychophysical properties remain unclear. This study aimed to investigate the effects of Delayed-Onset Muscle Soreness (DOMS) on the jaw's position sense (PS) and occlusal sensitivity (OS). METHODS: Twelve participants underwent intense concentric-eccentric jaw exercises. Self-reported muscle fatigue and pain, pain-free maximum mouth opening (MMO), pain pressure thresholds (PPTs) at right and left masseter and right and left anterior temporalis, maximum voluntary bite force (MVBF), PS, and OS were recorded before, immediately after, 24h, 48h, and one week after the exercises...
