A systematic review of observational studies were conducted in the following databases: An evaluation of titles and abstracts was conducted, nocyurno by the full reading of the articles to nis which researches would be included.

Observational studies that associated daytime and nighttime bruxism with salivary cortisol levels were included. Evaluation of the methodological quality was performed and extraction of data from the researches included. Two articles were included in this review. One of them showed moderate positive correlation between the BiteStrip scores and the levels of salivary cortisol in patients with bruxism. On the other hand, the other research demonstrated that children with sleep bruxism are more likely to have low levels of salivary cortisol.

There is no conclusive evidence of bocturno between bruxism and salivary cortisol. There is no pre-defined age range, occurring in children, teenagers and adults where it may be manifested in two distinct forms. The most predominant form could occur when the patient is awake daytime bruxism or more commonly, during sleep nocturnal bruxismin which it can be considered a stereotyped and periodic motion disorder Lavigne et al. In adults, the values are estimated from 3.

Bruxism presents diverse etiological factors, such as local, psychological, systemic, occupational and genetic Winocur et al. Secondary factors are also considered, such as medication, tobacco, alcohol, other drugs and the use of caffeine Sabuncuoglu et al. The cognitive and behavioral factors, such as anxiety and stress, generate hormonal responses, probably due to stimulation of the hypothalamus-pituitary-adrenal axis Refulio et al.

The product of this axis activation, the cortisol, which is secreted by the adrenal cortex, has its dispersion throughout all body fluids being detected in the urine, plasma and saliva Kanegane et al. Described as a hormone related to stress, it is responsible for important processes in the human body, such as glucose production and activation of anti-stress and anti-inflammatory processes Guglielmoto et al.

Therefore, salivary cortisol has been reported as a possible anxiety, stress and depression indicator Verdhara et al. A systematic review aimed to verify bruxismk association between daytime bruxism, anxiety, stress, depression and personality characters.

However, the scientificfindings were not sufficient to affirm that this association exists. The study was conducted from electronic search in the databases: All eligible articles published until January ofwithout language restrictions were included.

The following terms were used in the search strategy on Pubmed: The terms used in the search strategy on OVID were: The following terms were bruxiso in the search strategy on VHL: In order to identify some article not found in the databases, a search was conducted in the references of the articles included in the review. Inclusion and Exclusion Criteria. The inclusion criteria were observational studies with human beings, which evaluated the nodturno of daytime and nighttime bruxism with levels of salivary cortisol.

To be included, the studies had to measure the salivary cortisol levels and its association in patients diagnosed with noctyrno. The exclusion criteria of this study were. Case reports, technical notes, animal studies, in vitro studies, abstracts, textbooks, dissertations, opinion articles, review articles and studies that did not find the level of salivary cortisol. The articles selection underwent a careful and independent evaluation from two bruxis,o.

First, a reading of titles and abstracts from all databases found articles was performed.

The articles not related to the subject were excluded in this nioa. Those articles that generated doubt and those which appeared to fulfill all inclusion criteria, were accessed and read entirely.

During the reading of such articles, those that did not contemplate the inclusion criteria were excluded from this review. The studies that niis the inclusion criteria were included in the data extraction and qualitative analysis. This scale comprised the selection, comparison and results domains, in which the selection domain could reach a maximum of five stars, the comparison domain could reach a maximum of two stars, and the results domain a maximum of three stars.

Therefore, the studies could reach a maximum of ten stars, in which eight stars or more represented a low risk of bias; between seven and six stars, represented moderate risk of bias, and five stars or lower considered a high risk of bias. The following data, when available in the studies, were included in the final analysis of the selected articles: The studies selection is diagramed in Figure 1.

After the duplicates removal, the total found articles were For full reading, 10 articles were accessed, in which 8 articles were excluded for not meeting the eligibility criteria.

During the manual search in the references bruxksmo, additional articles were not found. Therefore, two publications were included in this review. One of the two articles, Karakoulaki et al. The participants age in this study eb from 25 to 52 years. The bruxism type evaluated was the nighttime bruxism, and the saliva collection timings were immediately after waking up and between 7 and 9 o’clock in the morning. The second article, Castelo et al. However, children with nighttime bruxism and 27 children without bruxism were noctuno, in Brazil.

The evaluation method for salivary cortisol quantity was through immune-enzymatic assay. The salivary cortisol levels were evaluated when the patient was still lying in bed after 30 minutes nocturbo waking up.

This study’s results showed that children with sleep bruxism are more likely to have lower concentrations of salivary cortisol OR: The methodology’s quality and consistency were considered moderate for the study by Karakoulaki et al.

Both studies showed flaws in sample size, compromising the score in the selection domain. Table 1 illustrates the quality evaluation of the selected studies Table I.

According to the judgment of the studies quality, moderate to high risk of btuxismo was observed in these studies. The great methodological differences found between the studies, such as the type of design, the scenarios where the researches took place, the studied groups variables and characteristics definitions, explains the findings of this research. Due to the high heterogeneity among studies and the large methodological differences between them, it was not possible to perform meta-analysis, which shows inos this subject should be explored in further research.

Bruxism consists of stereotyped movements characterized by teeth clenching and grinding and sn occur during the day or night. The literature converges in a multifactorial etiology for this behavior, however, there are hypothesis that anxiety and stress are primary factors for bruxism development Kampe et al. Currently, the saliva sample collection for investigation of bruxismi presence, bruxisml biomarker for stress, has been widely applied, mainly because it is a non-invasive, secure and simple method Refulio et al.

Thus, as the cortisol level and bruxism are both related to stress Karakoulaki et al. However, few studies were found in the present review. This review’s studies did not show a standardization related to the hour and repetition of sample collection. The circadian rhythm and stress are known factors for regulation brudismo salivary cortisol secretion, controlled by the circadian oscillator located in bruxism suprachiasmatic nucleus. This hormone shows higher levels in the morning and lower levels at dusk, implying directly in the hormonal levels evaluation Matsuda sn al.

In order to eliminate the variability caused by the circadian cycle, it is recommended that the salivary collections be held more times during the day. In the included studies, the collection was held when waking up Karakoulaki et al.

In his study, Karakoulaki et al. Greater quantities of saliva samples from each participant provide more reliable results, eliminating the variability caused by the circadian cycle. Investigations about the association between bruxism and stress provided contradictory results Karakoulaki et al. According to these authors, it is suggested that a relation exists between bruxism, high levels of salivary cortisol and stress perception as it was found by Winocur et al.

However, a study done by Nakata et al. The results from the studies by Karakoulaki et al. Pediatric bruxism is still poorly monitored due to lack of knowledge and consistent scientific evidence about the risk factors, pathophysiology, and their consequences. Apparently, pediatric bruxism is not associated with high salivary cortisol levels, as expected. On the other hand, Amato et al.

However, this study did not verify a direct association between bruxism and salivary cortisol levels. The results of this systematic review should be interpreted with caution due to methodological differences and limitations of the selected studies. First, the tests for salivary cortisol should be standardized and interpreted based on values obtained in the laboratory using samples from normal controls of the population, with different age groups and genders.

Another aspect to highlight concerns the design of the studies included in this review. In cross-sectional studies exposure and outcome measures are taken at the same time. The key issue in this type of design is the inability to know whether exposure salivary cortisol precedes or is a consequence of the health condition bruxism.

Ncoturno systematic review did not show conclusive scientific evidence between the salivary cortisol levels and bruxism. The small articles quantity that addresses the subject and the lack of methodological standardization suggests a need for new studies. Reported bruxism and stress experience.
