Oral Dis 2024; 30:2678-2684. [PMID: 37759359 DOI: 10.1111/odi.14714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 07/17/2023] [Accepted: 07/18/2023] [Indexed: 09/29/2023]
Abstract
AIM To evaluate the immediate and late impact of the COVID-19 pandemic on the occurrence of possible sleep bruxism (SB) among adolescents in Brazil. DESIGN This is a longitudinal study performed with adolescents (11-15 years old) from Southern Brazil. Baseline data were collected before the Brazilian COVID-19 outbreak (T1). Posteriorly, data were collected after 3 (T2) and 15 months under the Brazilian COVID-19 outbreak. The possible SB was evaluated by the question: 'Do you grind your teeth during your sleep?'. Sociodemographic, psychosocial and clinical variables were also collected. Changes in SB were evaluated by multilevel logistic regression models for repeated measures. RESULTS Of the 290 adolescents assessed at T1, 182 were reassessed at both follow-ups. The prevalence of possible SB was 13% at T1, 11% at T2 and 22% at T3. There were no immediate effects of the COVID-19 pandemic on the occurrence of possible SB (T2). Adolescents had odds 2.77 times greater of presented possible SB after 15 months (T3) of COVID-19 pandemic scenarios when compared to T1. CONCLUSION There was a considerable and late increase in the possible SB in adolescents in Brazil during the COVID-19 pandemic.

Abstract
BACKGROUND Bruxism has a multifactorial etiology, including the influence of sleep characteristics and chronotypes. AIM To identify the pathways that influence the occurrence of probable sleep bruxism (PSB) and probable awake bruxism (PAB) in adolescents. DESIGN A total of 403 adolescents, aged 12-19 years, participated in the study. Parents/caregivers filled out a questionnaire about sociodemographic issues and the adolescent's health conditions, and the adolescents about sleep characteristics, occurrence of bruxism (based on previous study and the International Consensus of Bruxism), and chronotype (Circadian Energy Scale). Clinical examinations were performed. Statistical analysis included descriptive analysis and path analysis. RESULTS PSB and PAB are related to each other, with moderate and positive correlation (β = .390). Poor sleep quality and higher household income had a direct effect on both PSB (β = -.138; β = .123, respectively) and PAB (β = -.155; β = .116, respectively). Chronotype had a direct effect on PSB, in such a way that adolescents with a morningness chronotype tend to have PSB (β = -.102). Adolescents that drool on the pillow (β = .184) and/or have agitated sleep (β = .104) tend to have PSB. CONCLUSION Poor sleep quality, household income, morningness chronotype profile, drooling on the pillow, and agitated sleep influence the paths taken by PSB. PAB was influenced by the quality of sleep and family income.

Abstract
Biomechanical studies play an important role in understanding the pathophysiology of sleep disorders and providing insights to maintain sleep health. Computational methods facilitate a versatile platform to analyze various biomechanical factors in silico, which would otherwise be difficult through in vivo experiments. The objective of this review is to examine and map the applications of computational biomechanics to sleep-related research topics, including sleep medicine and sleep ergonomics. A systematic search was conducted on PubMed, Scopus, and Web of Science. Research gaps were identified through data synthesis on variants, outcomes, and highlighted features, as well as evidence maps on basic modeling considerations and modeling components of the eligible studies. Twenty-seven studies (n = 27) were categorized into sleep ergonomics (n = 2 on pillow; n = 3 on mattress), sleep-related breathing disorders (n = 19 on obstructive sleep apnea), and sleep-related movement disorders (n = 3 on sleep bruxism). The effects of pillow height and mattress stiffness on spinal curvature were explored. Stress on the temporomandibular joint, and therefore its disorder, was the primary focus of investigations on sleep bruxism. Using finite element morphometry and fluid-structure interaction, studies on obstructive sleep apnea investigated the effects of anatomical variations, muscle activation of the tongue and soft palate, and gravitational direction on the collapse and blockade of the upper airway, in addition to the airflow pressure distribution. Model validation has been one of the greatest hurdles, while single-subject design and surrogate techniques have led to concerns about external validity. Future research might endeavor to reconstruct patient-specific models with patient-specific loading profiles in a larger cohort. Studies on sleep ergonomics research may pave the way for determining ideal spine curvature, in addition to simulating side-lying sleep postures. Sleep bruxism studies may analyze the accumulated dental damage and wear. Research on OSA treatments using computational approaches warrants further investigation.

Abstract
The prevalence of bruxism in the preschool population varies according to different investigations. The aim of this study was to investigate the prevalence of sleep bruxism and its relationship with social and orofacial factors in children aged 3 to 5 years. Three hundred forty-three preschool children were divided into two groups, one with nocturnal bruxism, as reported by parents, and another without this disorder. Questionnaires were distributed to the parents to determine the children's family social status and parafunctional habits at the time of the study. The clinical inspection confirmed the presence of certain parafunctional habits and the children's occlusal characteristics. The data obtained were analysed using descriptive statistics such as frequency chi-square tests to identify the influence of qualitative variables. Of the total sample, 28.9% of preschoolers presented sleep bruxism. The highest prevalence was observed in boys (61.6%) at the age of 5 years (41.4%). Characteristics associated with this pathology were lip incompetence, open bite, crossbite, and overbite, with p < 0.05. Sleep bruxism in preschool children has a higher prevalence in boys and is more frequently expressed from 5 years of age. Open bite, overbite, and crossbite should be considered factors associated with parafunction.

Abstract
The aims of this study were to perform an exploratory analysis of probable awake (AB) and sleep bruxism (SB) prevalence using of different diagnosis criteria based on the International Consensus; evaluate the associations between self-report and clinical signs/symptoms in adolescents. Participated in this cross-sectional study 403 adolescents aged 12- to 19-years-old enrolled in public and private schools from Belo Horizonte, Brazil. Parents/caregivers answered a questionnaire about sociodemographic status and adolescents' health status. Adolescents answered a questionnaire evaluating AB (e.g., grinding and clenching) and SB (e.g., grinding, bracing, and thrusting) activities and frequent headaches. A clinical examination was performed on adolescents to evaluate bruxism clinical signs/symptoms (pain upon palpation on masseter and temporal, linea alba, indentation on the tongue and attrition wear severity). Descriptive statistics and Pearson's Qui-square test were performed (P≤0.05). Adolescents mean age was 14.3±1.5 years, and 58.1% were female. Self-report of SB was identified in 31% of participants and self-report of AB in 51.6%. Almost all adolescents (99%) presented at least one tooth with attrition wear (98.5% on enamel and 0.5% on dentin), with a mean number of 12.4±5.7 teeth. Depending on the diagnosis criteria, the prevalence of probable SB and AB varied from 0- 99% and 0.2- 99%, respectively. A high inconsistency was found for the prevalence of probable AB and SB in adolescents, which were influenced by the different clinical sings/symptoms used as diagnosis criteria. Frequent headaches and pain upon palpation on masseter and temporal muscle were associated to self-report of AB and SB among adolescents.

Are lower urinary tract conditions more common in children with sleep bruxism? J Pediatr Urol 2022; 19:176.e1-176.e6. [PMID: 36522240 DOI: 10.1016/j.jpurol.2022.11.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 11/22/2022] [Accepted: 11/25/2022] [Indexed: 12/02/2022]
Abstract
INTRODUCTION Sleep bruxism is a parasomnia caused by rhythmic and non-rhythmic activity of the masticatory muscles during sleep. Prevalence of sleep bruxism is reported up to 40.6% in the literature. Sleep bruxism is a multifactorial issue and associated with multiple dental complications, sleep-related disorders, and psychosocial problems. We aimed to investigate if children with sleep bruxism suffer more from lower urinary tract conditions. MATERIALS AND METHODS Prospectively 128 children were included in this study. Sixty-four children constituted in the bruxism group and 64 children constituted in the control group. Children who admitted to the pediatric dentistry clinic with bruxism symptoms were recruited in the bruxism group. Control group constituted of consecutive 64 children who admitted to the pediatric dentistry clinic for routine dental examination. Parents were asked to fill out a questionnaire including Dysfunctional Voiding and Incontinence Scoring System (DVISS) form. Children's demographic data, presence of urinary frequency, presence of urgency, behaviour of voiding postponement, presence of daytime urinary incontinence, presence of enuresis nocturna, presence of fecal incontinence, presence of constipation, status of circumcision, and presence of bruxism related symptoms were recorded. Children with a DVISS score above 8 were considered to have functional voiding disorder. All children underwent a dental examination. RESULTS The mean age of children was 73.3 ± 26.9 months. For all children (n = 128), the girl to boy ratio was 40:88. Mean DVISS score was 2.5 ± 3.8 and the mean QOL score was 0.1 ± 0.4 for all children. Eight (6.3%) children were found to have functional voiding disorder based on the DVISS score. There was no statistically significant difference for any lower urinary tract condition between the bruxism group and the control group (Table). Children with bruxism significantly had more tooth wear and masseter muscle hypertrophy (<0.001 and < 0.05). DISCUSSION Sleep bruxism has been linked to a number of health issues including dental, systemic and psychosocial problems. Tooth wears, fatigue/pain in chewing muscles, gum recession, facial pain, masseter muscle hypertrophy and temporomandibular joint damage are the main complications of bruxism. Moreover, bruxism has been associated with systemic diseases and sypmtoms like asthma, respiratory illnesses, enuresis nocturna, anxiety, and stress. CONCLUSIONS Children with sleep bruxism suffer more from tooth wear, masseter muscle hypertrophy, and regional pain over the jaw. Additionally morning fatigue, relationship issues, and respiratory illnesses are more common in bruxist children. Lower urinary tract conditions are not more frequent in children with sleep bruxism.

Abstract
OBJECTIVE Burnout syndrome has negative consequences on the dentist's health and performance during work. This systematic review aimed to assess the prevalence of Burnout syndrome in dentists. METHODS Searches were carried out in Medline, Scopus, Web of Science, PsycINFO, EMBASE, LILACS databases, and searches in the gray literature on January 27, 2021. There were no restrictions on language and search period. For the diagnosis of Burnout, only studies that used the Maslach burnout inventory questionnaire and its subscales emotional exhaustion (EE), depersonalization (DP), and reduced personal accomplishment (PA) were included. Proportion meta-analyses were performed using the Stata 13.0 software. RESULTS A total of 37 articles were included in the narrative and 31 in quantitative syntheses. The overall prevalence of Burnout syndrome in dentists was 13% (95% confidence interval [CI]: 0.006-0.21; I²: 97.07%) and the total prevalence in the subscales EE, DP, and PA, were, respectively: 28% (95% CI: 0.24-0.32; I²: 20.70%), 18% (95% CI: 0.08-0.28; I²: 85.61%) and 10% (95% CI: 0.08-0.13; I²: 0%). About the levels of Burnout syndrome in the subscales, 25% (95% CI: 0.19-0.31; I² 92.58%) presented high EE, 18% (95% CI: 0.10-0.26; I² 96.62%) high DP and 32% (95% 0.20-0.45; I² 97.86%) low PA. About continuous data, the mean of EE, DP and PA was respectively 17.90 (95% CI: 9.36-26.43; I² 94.8), 6.93 (95% CI: 3.41-10.45; I² 80.2) and, 34.69 (95% CI: 23.82-45.55; I² 98.8). No study presented all the positive criteria of the Joanna Briggs Institute Critical Appraisal checklist. CONCLUSION In conclusion, there was a considerable prevalence of burnout syndrome in dentists, mainly in the subscale of emotional exhaustion.

Abstract
OBJECTIVE To evaluate the association between the severity of possible sleep bruxism (PSB) and possible awake bruxism (PAB) and attrition tooth wear facets (ATWF) in children/adolescents. METHODS Four hundred-thirty-four children/adolescents enrolled in schools in Lavras, Brazil, participated in this cross-sectional study. Caregivers answered a questionnaire about their childrens' PSB. Children/adolescents answered a questionnaire about the occurrence of PAB. RESULTS ATWF among individuals without PSB and PAB was lower than those with moderate/severe PSB (p = 0.038) and moderate/severe PAB (p = 0.003). ATWF in anterior teeth was lower among individuals without PSB compared to those with mild (p = 0.015) and moderate/severe PSB (p = 0.032). ATWF in posterior teeth was lower among individuals without PAB compared to those with mild (p = 0.046) and moderate/severe PAB (p = 0.017). CONCLUSION The number of attrition tooth wear facets is proportional to the severity of PSB and PAB.

Abstract
OBJECTIVE to investigate the impact of the severity of microcephaly caused by the Zika virus (MCZ) on tooth eruption and orofacial structures of children. DESIGN This case series study developed the research at the Mens Sana Rehabilitation Center, Arcoverde, Brazil. The study included 27 children diagnosed with MCZ. We performed the data collection in June 2018 through a questionnaire answered by the legal guardians, followed by a clinical examination of the children. The data were analyzed by the Mann-Whitney and Fisher's Exact tests (p = 0.05). RESULTS The final sample was composed of 20 children. Of these, 13 (35.0%) had severe microcephaly, 5 (30.0%) had altered sequence of tooth eruption, 10 (50.0%) had delayed eruption, and the mean number of decayed teeth was 2.3. The most identified orofacial changes were teeth grinding habit (65.0%), difficult chewing (50.0%), and non-nutritive sucking (50.0%). Mann-Whitney test showed that the severity of microcephaly did not affect tooth eruption (p = 0.581). Fisher's exact test showed that the severity of microcephaly was not associated with orofacial changes (p > 0.05). CONCLUSIONS The severity of MCZ does not seem to influence changes in deciduous tooth eruption and the presence of orofacial anomalies.

Exposure to second-hand smoke during early life and subsequent sleep problems in children: a population-based cross-sectional study. Environ Health 2021; 20:127. [PMID: 34920730 PMCID: PMC8684187 DOI: 10.1186/s12940-021-00793-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 10/04/2021] [Indexed: 06/01/2023]
Abstract
BACKGROUND Previous studies have revealed that current secondhand smoke exposure showed highly suggestive evidence for increased risk of simultaneous sleep problems in children. Data on the associations between early-life exposure to SHS with subsequent sleep problems in children were scarce. We aimed to evaluate the associations of early-life SHS exposure with sleep problems in children. METHODS In this cross-sectional study, children were recruited from elementary and middle schools in Liaoning Province, China between April 2012 and January 2013. We assessed early-life SHS exposure (pregnancy and the first 2 years of life) via questionnaires. Sleep problems and different types of sleep-related symptoms were measured based on the validated tool of the Sleep Disturbance Scale for Children (SDSC). Generalized linear mixed models were applied to estimate the associations of early-life SHS exposure with sleep problems. RESULTS We included a total of 45,562 children (22,657 [49.7%] males; mean [SD] age, 11.0 [2.6] years) and 6167 of them (13.5%) were exposed to early-life SHS during both pregnancy and the first 2 years of life. Compared with unexposed counterparts, children exposed to early-life SHS had higher total T-scores of SDSC (β = 4.32; 95%CI: 4.06, 4.58) and higher odds of increased sleep problems (OR = 2.14; 95%CI: 1.89, 2.42). When considering different sleep-related symptoms, the associations between early-life SHS exposure and symptom of sleep-wake transition disorders (i.e., bruxism) were the strongest in all analyses. CONCLUSIONS Early-life SHS exposure was associated with higher odds of global sleep problems and different sleep-related symptoms in children aged 6-18 years. Our findings highlight the importance to strengthen efforts to support the critical importance of maintaining a smoke-free environment especially in early life.
