Bruxism is a behavior characterized by clenching and/or grinding of 
teeth, and/or by bracing or thrusting of the jaw muscles [1,2].While upper facial movements were
unaffected, the deficits in lower facial mobility underscore the broader neuromuscular
implications of bruxism.First-line 
therapy involves raising the patient's awareness to monitor his 
parafunctional and del etere behavior, and consequently to change 
and stop it. We will first clarify the definition and physiopathology of 
bruxism in the light of recent publications in addition to outlining the 
epidemiology with the various signs and etiological factors, as well 
as the different comor-Bidities.Genetics, Environment, and lifestyle 
factors have been associated with increased susceptibility of AB 
occurrence in dif-ferent age groups [4].But if occlusion is our concern both 
functionally and aesthetically, we must also monitor its 
physiological evolution
Clearer knowledge of these features will enable dental 
professionals to better screen those patients at risk and monitor 
them in order to prevent any worsening of their condition, whatever 
the prognosis, and to ask the relevant questions concerning 
potential risks for further growth in relation to temporomandibular 
dysfunction (TMD).Research by
Manfredini et al. (2009) identified stress and psychosocial factors as primary
contributors to AB. Importantly, these stressors not only exacerbate bruxism but can
also perpetuate a cycle of worsening symptoms, impacting overall well-being.A
study by Salah et al. (2022) found that individuals with bruxism exhibited significantly
reduced lower facial movement coordination, particularly during tasks requiring dynamic
facial expression.Therefore, this clinical study aimed to evaluate AB 
frequency in college preparatory students and its correlation with 
levels of anxiety, depression, stress, and Oral health-Related quality 
of life (OHRQoL). Although previous studies [15-17] have tried to associate the 
presence of oral parafunctions with the academic stage (high 
school, undergraduate, graduate), the correlation between AB 
frequency and psychological factors has not been described.Prevalence and Epidemiology
Bruxism is a common condition worldwide, affecting approximately 12.8% of people for
SB and between 22% and 31% for AB, based on population studies (Manfredini et al., 2013).Adolescents and young adults are disproportionately affected, with prevalence
peaking in this demographic due to various factors, including academic stress, digital
media usage, and erratic sleep patterns.Some authors [9] 
demonstrated high prevalence of TMD signs and symptoms in 
college preparatory stu- dents, which were associated with 
emotional tension, anxiety, and oral parafunctions.1).
