The craniomandibular dysfunction (CMD) is a pathology that can appear at early ages. In a sample of 36 childrenresiding in Madrid (Spain), of both sexes, with ages between 7 and 13 years, the prevalence of signs and symptomsof CMD was analyzed. For that purpose, we did a dental and muscular examination, together with temporomandibularjoints, functional and occlusal examination, and completed with a specific questionnaire. The results revealedthat 100% showed some sign or sympthom of CMD. 77,8% of the pacients presented 3 or more CMD signs.The most prevalent were painful muscle palpation (94,4%), together with sliding anteriorly (91,7%), painful jointpalpation (69,4%), wear facets in permanent teeth (41,7%) and altered opening and closing trayectory (38,9%). Onthe other hand, only 38,9% showed any CMD symptom. The most prevalent symptoms were night teeth grinding(27,8%), followed by tooth sensitivity (19,4%) and fullness in the ears (16,7%). We conclude that in our sample,25% presented mild CMD (less that 3 signs or symptoms), 58,3% presented moderate CMD (from 3 to 6 signs orsymptoms) and 16,7% showed severe CMD (more than 6 symptoms). Nevertheless, it’s important to remark thatnone of these pacients came seeking treatment for his CMD and these symptoms were refered only when beingasked. Hence the importance of a comprehensive clinic history to precociously diagnose this pathology and havethe ability to prevent its progression.

The Relationship

Teeth clenching during exercise is important for sports performance and health. Recently, several mouth guard (MG)-type wearable devices for exercise were studied because they do not disrupt the exercise. In this study, we developed a wearable MG device with force sensors on both sides of the maxillary first molars to monitor teeth clenching. The force sensor output increased linearly up to 70 N. In four simple occlusion tests, the trends exhibited by the outputs of the MG sensor were consistent with those of an electromyogram (EMG), and the MG device featured sufficient temporal resolution to measure the timing of teeth clenching. When the jaw moved, the MG sensor outputs depended on the sensor position. The MG sensor output from the teeth-grinding test agreed with the video-motion analysis results. It was comparatively difficult to use the EMG because it contained a significant noise level. Finally, the usefulness of the MG sensor was confirmed through an exercise tolerance test. This study indicated that the developed wearable MG device is useful for monitoring clenching timing and duration, and the degree of clenching during exercise, which can contribute to explaining the relationship between teeth clenching and sports performance.

Momentary Assessment

Diagnosis of Awake Bruxism (AB) is problematic due to the inability to use continuous recordings during daytime activities. Recently, a new semi-instrumental approach was suggested, viz., an Ecological Momentary Assessment (EMA), with the use of a smartphone application. With the application subjects are requested to report, at least 12 times per day, the status of their masticatory muscle activity (relaxed muscles, jaw bracing without tooth contact, teeth contact, teeth clenching or teeth grinding). The aim of the present study was to compare the EMA to the assessment of AB as defined by a single point self-report. The most frequent condition recorded by the EMA was relaxed muscles (ca. 60%) and the least frequent one - Teeth grinding (0.6 %). The relaxed muscle condition also showed the lowest coefficient of variance over a 7day period of report. Additionally, only the relaxed muscles and the Jaw bracing conditions presented an acceptable ability to discriminate between AB positive and AB negative subjects, as defined by single point self-report questions. The combination between self-report and EMA may have a potential to promote our ability to diagnose AB. We suggest to re-consider the conditions of Teeth contact and Teeth grinding while using EMA to evaluate AB.

Solution Design

Face teeth grinding of special tools, as hobing worm milling cutters are, is the shape and cinematically complex operation with the respect to achieving the necessary accuracy and resultant shape geometry. The grinding wheel shape, it ́s size and the control helix angle of hobing worm are the primary factors which are compelling the ground groove accuracy during the face teeth sharpening process. Inappropriately selected combination of these parameters causes undercut of this surface and the negative impact on required accuracy. The main aim of the solution is to find a variable and to create a parametric mathematical model to calculate appropriate grinding wheel shape according to the input factors – hobing worm and grinding wheel parameters which affects this issue. This system will be used to create the initial grinding wheel surface and a helix groove undercut calculation program. The graphical part of this programme will be the next benefit.

In clinical practice, patients suffering from an occlusal parafunctional activity have increased. It can be observed that a negative influence of environment aggravates patient’s health. The aim of this paper is to present the impact of environment and development of human civilization on the prevalence of bruxism and the correlation between them. The authors grasp the most relevant aspects of psychological and anthropological factors changing over time as well as their interactions and describe a relationship between chronic stress and bruxism. Current literature shows how contemporary lifestyle, working environment, diet, and habits influence the patient’s psychoemotional situation and the way these factors affect the occluso-muscle condition.
