Abstract:

Introduction:
Bruxism is a parafunctional activity characterized by clenching and/or rubbing of the teeth, is of multiple etiology and is mainly associated with psychological stress, anxiety and sleep disturbances. Anxiety is an emotion characterized by apprehension and somatic symptoms of tension where an individual anticipates impending danger, catastrophe or misfortune, the body often mobilizes to meet the perceived threat muscles tense, breathing quickens and the heart beats faster. The role that such anxiety plays is different according to the intensity with which it is presented. In this sense, mild or moderate levels of this sensation have beneficial effects, since they promote better performance in the realization of diverse activities. However, when it reaches exaggerated levels, it can cause a total and permanent deterioration, bringing with it serious complications in the areas of health, work, and academics, and even the excessive use of drugs.

Most authors agree that emotional stress are the most influential factors in the presence of Bruxism, being of great importance to reduce the severity of these psycho-emotional states through the use of techniques such as: improving sleep quality, biofeedback, meditation and relaxation techniques, pharmacotherapy with anxiolytics, etc. The quality of life we are talking about today refers to a concept that can be perceived at different levels, visualizing biological, economic, social and psychological needs from the individual to the social level. The objective of this work was to identify the presence of bruxism and its relationship with the emotional state in young university students.

Methodology:
Cross-sectional, non-experimental, descriptive study, with a sample of 153 students of the Faculty of Dentistry. The CBA instrument (self-reported bruxism questionnaire) for this pathology was applied by electronic survey. And the WHOQOL-100 in the 26-question version, is an instrument that is responsible for analyzing how people perceive their position in life within the cultural framework and value systems in which they are immersed, in relation to their goals, expectations, standards and problems.

Results:
The total sample consisted of 153 students, of which 64.1% were female (98) and 36.1% (55) were male. The survey was directed to university students in an age range of 18 to 30 years in which the highest prevalence was obtained in students between 21 and 23 years of age, corresponding to 60%. It has been observed that 42.5% of university students tend to clench or grind their teeth during the course of the day, while the remaining 57.5% respond that they do not feel any discomfort. About 39.2% of the university population presents dental wear. It has been observed that 44.7% of the young people who clench or grind their teeth do so while sleeping. 21.6% of the young people reported emotional changes as a result of their dental problems. It was found that the general quality of life index is 62, which indicates a perception of regular quality of life, which allows an adequate development from the subjective point of view.

Conclusions:
The present investigation led us to determine that the presence or not of symptoms of probable bruxism or definitive bruxism symptoms does not have a significant incidence in relation to the general quality of life index of the World Health Organization, since the results of the instruments applied to the participants reflect this.
