A study on digital tooth preparation assessment software in undergraduate pre-clinical skills teaching.

Introduction: Aims This research aims to evaluate the effectiveness and efficiency of the PrepCheck digital system as an additional feedback tool in enhancing undergraduate dental students' tooth preparation skills and its potential to enhance students' learning experience.

Material And Methods: A total of 55 BDS3 students attending the "Crowns Course" and divided into three groups participated in the study. One group (n = 24) was randomly selected as the case group and received feedback using the digital tooth preparation analysis system, PrepCheck, alongside standard visual assessment.

Radiotherapy and the oral environment the effects of radiotherapy on the hard and soft tissues of the mouth and its management.

Radiation therapy plays an important role in the care of patients with head and neck cancer. When the oral cavity and the salivary glands are exposed to high doses of radiation, there can be dramatic effects on the patient's oral health. The clinical consequences of radiation can include mucositis, hyposalivation, taste loss, osteoradionecrosis, radiation caries and trismus.

The inhibitory effect of a chewing task on a human jaw reflex.

This study was undertaken to investigate whether an inhibitory jaw reflex could be modulated by experimentally controlled conditions that mimicked symptoms of temporomandibular disorders. Reflecting on previous work, we anticipated that these conditions might suppress the reflex. Electromyographic recordings were made from a masseter muscle in 18 subjects, while electrical stimuli were applied to the upper lip.

Reproducible effects of subjectively assessed muscle fatigue on an inhibitory jaw reflex in humans.

Objective: To evaluate the effects of exercise-induced, subjectively assessed muscle fatigue on an inhibitory jaw reflex, evoked by electrical stimulation of the upper lip. In addition, the reproducibility of these effects was assessed.

Design: Eight subjects participated in two experimental sessions that were two weeks apart.

The effects of a maximal jaw clench on an inhibitory jaw reflex.

The purpose of this study was to determine whether mimicking symptoms of temporomandibular disorders by experimentally activating deep nociceptors in the oro-facial region, can modulate an inhibitory jaw reflex. In human subjects, electromyograms were recorded from one (eight subjects) or both (16 subjects) active masseter muscles and electrical stimuli were applied to the upper lip. This procedure was performed before and after a 30-s conditioning period in which the subjects maximally clenched the jaw.
