Factors associated with bruxism in children with developmental disabilities

Oral Health Care for Children and Youth With Developmental Disabilities: Clinical Report

Oral health is an essential component of overall health for all individuals. The oral health of children and youth with developmental disabilities (CYDD) involves unique characteristics and needs of which pediatricians and pediatric clinicians can be aware. Risk for oral disease in CYDD is multifactorial and includes underlying medical conditions, medications, and ability to participate in preventive oral health care and treatment, and lack of access to providers is common for this population despite being eligible for Medicaid. Pediatric clinicians are uniquely positioned to support the oral health needs of CYDD and their families through the medical home. This clinical report aims to inform pediatric clinicians about the unique oral health needs of CYDD. It provides guidance on assessing caries risk and periodontal status using structured screening instruments; understanding dental trauma, the role of diet and caries risk, trauma prevention, and malocclusion; and providing anticipatory guidance on oral hygiene that includes tooth brushing, use of fluoridated toothpaste, assessing community water fluoridation, advocating for a dental home by 1 year of age, and transition to adult dental care as part of adolescent health care. It also highlights special considerations for dental treatment rendered under sedation or general anesthesia that CYDD may need. Pediatric clinicians can help reduce risk of CYDD developing dental disease by understanding the unique needs of their patients and their barriers to accessing oral health care in their community, communicating with the child's dental home, and advocating for safe and accessible dental procedures.

Bruxism, parafunctional oral habits and oral motor problems in children with spastic cerebral palsy: A cross-sectional study

BACKGROUND

Individuals with spastic cerebral palsy are more predisposed to parafunctional oral activities and oral motor problems because of spasticity.

OBJECTIVES

The aim of the study was to evaluate the relationship between the gross motor function classification system score (GMFCS), age, bruxism, parafunctional oral habits and oral motor problems in children with cerebral palsy.

METHODS

This cross-sectional study included 63 children with spastic cerebral palsy, aged 3-18 years, with developmental disabilities. The relationship between parentally reported bruxism, parafunctional oral activity rates, oral motor problems, and GMFCS was analysed.

RESULTS

The prevalence of bruxism was 52.4%, and the rate decreased as age increased. There was a greater likelihood of bruxism in individuals with tongue thrust (OR [95% CI] = 8.15 [1.4-47.3]) and swallowing problems (OR [95% CI] = 5.78 [1.3-24.68]).

CONCLUSION

In children with spastic cerebral palsy, bruxism and the rate of parafunctional oral habits were high, thus affecting oral motor activities. A relationship was found between oral motor problems and increased GMFCS levels, but no relationship was found between bruxism and GMFCS levels. Children with spastic cerebral palsy who display tongue thrust or swallowing problems have an increased likelihood of presenting with bruxism.

A scoping review of oral health outcomes for people with cerebral palsy

INTRODUCTION

Good oral health is important for good overall health. Studies have reported poorer oral health outcomes for people with cerebral palsy, but there has been no synthesis of the evidence surrounding this and, there are no clear oral health recommendations for people with cerebral palsy globally. This review synthesizes the existing knowledge base on oral health in people with cerebral palsy and provides recommendations for future research.

METHODS

A scoping review was conducted to assess the current literature. Databases were searched using relevant search terms. Study outcomes were synthesized according to their reported outcomes.

RESULTS

One hundred seventy three studies were included in this review. Children with cerebral palsy have an increased risk for dental caries and untreated caries. Higher saliva osmolality is a major contributor to increased dental caries. People with cerebral palsy are more likely to experience tooth wear and bruxism. Children and their care-givers have poor oral health related quality of life. There is a large unmet need for oral healthcare in this group. There is no suggested plan for the prevention of poor oral health for this group. A high number of studies included related to research is conducted in low- and middle-income countries, care should be taken in applying results outside this context. There is a lack of research conducted in people with cerebral palsy, 18 years and over.

CONCLUSION

There is a higher risk for poor oral health in people with cerebral palsy and there is a large unmet need to dental care in this group. This study highlights the need for further research to focus on adults with cerebral palsy and an of understanding the oral health care outcomes in the context of settings. The authors recommend the inclusion of classification systems and the integration of disability inclusive language in future studies.

Non-surgical interventions for the treatment of masticatory muscular spasticity in patients with cerebral palsy. Systematic review of randomized clinical trials

INTRODUCTION

Muscle disorders caused by cerebral palsy (CP) can affect oral function. The treatment for masticatory muscle spasticity is important to minimize muscle hyperactivity and preclude oral damages.

OBJECTIVES

To evaluate the efficacy and safety of non-surgical interventions for the treatment of masticatory muscle spasticity in CP patients.

METHODS

A comprehensive search was performed in the following databases: MEDLINE, Embase, Cochrane Library, LILACS, BBO, PEDro, Clinicaltrials.gov and WHO/ICTRP, without date and language restrictions. Randomized controlled trials (RCT) evaluating non-surgical interventions were considered. Primary outcomes such as masticatory function and adverse events were planned to be assessed. The risk of bias assessment was performed using the Cochrane risk of bias tool. The certainty of the evidence was assessed using the GRADE approach.

RESULTS

Three RCT assessing the effects of botulinum toxin, functional masticatory training and neuromuscular electrostimulation (NMES) were included. Evidence with a very low certainty showed: (i) no difference between botulinum toxin and placebo regarding maximum chewing strength, chewing efficiency and global oral health scale; (ii) improvement in masticatory function in favor of functional masticatory training versus conventional exercises, and (iii) in favor of strengthening exercises plus NMES versus placebo.

CONCLUSIONS

There was insufficient evidence to support the use of botulinum toxin and masticatory muscle strengthening programs alone and associated with NMES for the treatment of masticatory muscle in patients with PC. The clinical decision must be individualized, and further studies are needed to support or refute the use of different non-surgical interventions for PC. PROSPERO register number CRD42020209761.

Prevalence of bruxism in adults with cerebral palsy institutionalized in Lisbon

OBJECTIVE

To determine the prevalence of bruxism in individuals with cerebral palsy (CP) and evaluating the various factors associated METHODS: One hundred and ten adults diagnosed with CP were selected from six institutions for people with special needs. Data were collected through oral examinations using the diagnostic criteria proposed by the American Academy of Sleep Medicine and the modified scale of Asworth RESULTS: Of the total sample, spastic tetraplegia was the most common type and half of the population presents severe intellectual disability. The prevalence of bruxism was 74,5%. Wear facets were observed in 67.9% of the sample, 59.1% of which were brilliant. There was a positive association between mixed bruxism (MB) and the spasticity classification. Through a logistic regression it was found that the risk of having MB and general bruxism (GB) is greater in individuals who have shiny wear facets.

CONCLUSIONS

In the present study the high prevalence of GB indicates there is an urgent need for treatment options in people with CP. More studies are needed with standardized diagnostic protocols and representative samples to evaluate the factors that influence the presence of bruxism in this population and to establish an appropriate treatment planning.

Risk factors associated with reported bruxism among children and adolescents with Down Syndrome

Objective: Identify factors associated with the prevalence of reported bruxism in children/adolescents with Down Syndrome (DS). Methods: The study included 112 children/adolescents with DS and their parents/caregivers. Oral habits, pacifier/finger sucking, upper respiratory infections (<six months), and breathing type (nasal/buccal) were diagnosed. Reported bruxism was recorded through parents' report ("Does your child have audible teeth grinding?"). Results: Children/adolescents 8-12 years of age were 1.15 times more likely to belong to the group with reported bruxism (1.42-3.14). Children/adolescents 5-7 years of age were 3.38 times more likely to belong to the group with reported bruxism (1.26-9.03). Children/adolescents classified as mouth breathers were 2.87 times more likely to belong to the group with reported bruxism (1.18-6.98). Conclusion: Age and mouth breathing were associated with reported bruxism. Earlier interventions should be provided in order to limit and minimize possible damage that can affect childrens' quality of life.

Risk factors for dental caries in children with developmental disabilities

The aim of the present study was to investigate risk factors for dental caries in children with developmental disabilities who were treated at a clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 401 dental charts of individuals without dental caries or restorations in their first dental appointment. The dependent variable was the time of occurrence of new dental caries or restorations and was measured in months. Gender, age, International Code of Diseases (ICD), mother´s education, sugar consumption, use of fluoride toothpaste, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic or asthma drugs, and history of asthma were covariates. The Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental caries/restoration was equal to 107.46 months (95%CI 95.41 to 119.51), with a median of caries-free children up to 94 months. For each point increase in the scale of sucrose consumption, the increase in caries risk was 1.07 (95%CI 1.01 to 1.15). Sucrose consumption was the only risk factor for dental caries found in this group of individuals with developmental disabilities.
