Impact of Distress Level, Sleep Quality and Occlusal Trauma on Periodontal Status Among Bruxers

Impact of Distress Level, Sleep Quality and Occlusal Trauma on Periodontal Status Among Bruxers - a Cross Sectional Study

Increased distress levels and impaired sleep quality are known to exacerbate bruxism by enhancing masticatory muscle activity, leading to excessive and prolonged occlusal forces. These abnormal forces may result in occlusal trauma, which can compromise the adaptive capacity of the periodontal tissues by increasing tooth mobility, widening the periodontal ligament space, and accelerating alveolar bone loss, particularly in the presence of existing periodontal inflammation. Although occlusal trauma alone may not initiate periodontal disease, it can act as an important modifying factor in disease progression. Despite the recognized individual associations of distress, sleep quality, bruxism, and periodontal health, limited evidence exists regarding their combined impact on periodontal status among bruxers. Therefore, evaluating the influence of distress level, sleep quality, and occlusal trauma on periodontal status is essential to better understand disease progression and to facilitate comprehensive, multidisciplinary management strategies for individuals with bruxism.

Detailed Description

The periodontium in sleep bruxism patients suffers from excessive occlusal force for long periods of time during sleep, the function of the periodontium in such patients may differ from that in patients without sleep bruxism.

Bruxism is associated with tooth wear, chipping, cracking, and fracture, tooth mobility, gingival recession, pain, and sensitivity. Tooth mobility can be a serious consequence of bruxism. Tooth mobility has been described as one of the common clinical signs of occlusal trauma. Progressive mobility may be suggestive of ongoing occlusal trauma, but assessments at different time points are necessary to make this determination.

Bruxism has multifactorial etiologies involving central nervous system regulation, psychosocial factors such as stress, and peripheral influences such as occlusal interferences. Psychological stress and poor sleep quality are commonly reported in individuals with sleep bruxism. Sleep disturbances have been linked to elevated muscle activity and increased parafunctional events, potentially contributing to adverse oral health outcomes. Additionally, poor sleep quality has been associated with diminished overall health and may exacerbate inflammatory responses, which are central to periodontal disease progression. These may contribute to adverse oral health outcomes by preventing the "rest and repair" cycle necessary for tissue health. Stress levels and poor sleep quality negatively affect systemic health. These effects are mediated through direct mechanisms such as systemic inflammation, oxidative stress, and immune system impairment, as well as indirect mechanisms involving associated compensatory behaviors. Given that inflammation and oxidative stress are key components in the pathogenesis of periodontitis. Previous epidemiological studies have identified high perceived stress and poor sleep quality as modifiable risk indicators for periodontitis. When stress levels remain chronically elevated and recovery is insufficient due to poor sleep quality, chronic allostatic load responses and dysregulated immune and inflammatory processes are further activated. Therefore, it can be hypothesized that the combined presence of high stress and poor sleep quality may have a more pronounced detrimental effect on the periodontium than either factor alone.

However, inconsistent and conflicting findings have been reported between relationship of stress, sleep quality, and bruxism as a result, highlighting the need for integrated evaluation of these factors within dental research.

In the context of bruxism, occlusal trauma is significant because the repetitive nature of occlusal loading may potentiate periodontal tissue destruction beyond the effects of microbial plaque alone.

Given the multifactorial nature of bruxism and periodontal disease, understanding how psychological (stress), psychological and behavioral (sleep quality), and mechanical (occlusal trauma) factors influence periodontal health in bruxers could enhance diagnostic precision and therapeutic strategies. This study aims to evaluate these relationships to clarify their impact on periodontal status.
