Frequency of parafunctional oral habits in patients with cerebral palsy

Prevalence of Bruxism in Children and Adolescents with Cerebral Palsy: Systematic Review and Meta-analysis

AIMS

To perform a systematic review and meta-analysis compiling data on the prevalence of bruxism in children and adolescents with cerebral palsy.

METHODS AND RESULTS

Searches were carried out in PubMed/Medline, Web of Science, and Scopus databases to identify the articles published by February 2023. Two independent reviewers, and in duplicate, employed a two-stage process to select publications. The same two reviewers performed the data extraction. Studies were included when the following eligibility criteria were met: performed in children and/or adolescents with cerebral palsy and reporting bruxism. Potentially eligible studies were read in full and excluded that: not presented numerical data on the prevalence of bruxism; not reported how the bruxism was assessed; not reported data about the cerebral palsy; and not an observational study. The risk assessment of bias was assessed by the Newcastle- Ottawa Scale. After reading the titles and abstracts of the 358 identified articles, eight articles from 1966 to 2020 were included. The main reason for not including the studies was not to report data about bruxism (59.3%), and 44.5% were excluded for not reporting data from patients with cerebral palsy. The studies were carried out in schools, university hospitals, or centers for patients with special needs (Brazil, the United States, and Egypt). The pooled prevalence of bruxism in children and adolescents with cerebral palsy was 46% (95%CI: 0.38-0.55) after removing one study.

CONCLUSION

The pooled prevalence of bruxism in children with cerebral palsy can be considered high since almost half of the studied population is affected by this condition. PROSPERO #CRD42021225781.

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.

Childhood and Adolescents Sleep Bruxism Treatment: A Systematic Review

Introduction  Sleep Bruxism (SB) is a common condition in childhood that can cause multiple consequences such as abnormal tooth wear, tensional headaches, masticatory muscle pain, or fatigue. The literature reports some interventions, however the treatment for SB in children is not well-established. Objectives  A systematic review was performed to investigate the effectiveness of the treatments described for SB in children and adolescents: pharmacological and psychological treatments; behavioral guidelines; and dental approaches. Materials and methods  Randomized clinical trials comparing different SB treatments with a control group were searched in the electronic databases PubMed, Scopus, Web of Science, Cochrane Library, and VHL until August 04, 2021. Two independent reviewers selected the studies, extracted the data, and assessed the risk of bias. After a two-phase selection process, 07 articles were selected. The methodology of the selected studies was analyzed using the Cochrane Risk of Bias Tool. The criteria used to qualify the studies were based on randomization, allocation, blinding of participants and evaluators, and analysis of results. Results  The signs and symptoms of SB were reduced with pharmacotherapy (hydroxyzine/diazepam) and medicinal extracts ( M. Officinalis ), but with occlusal splints and physiotherapy, this improvement was not statistically significant when compared to control groups. Conclusion  Some evidence of the efficacy of pharmacotherapy (hydroxyzine/diazepam) and medicinal extracts ( M. Officinalis ) was found. However, this systematic review is not enough to establish a protocol for the treatment of SB. Besides, the individualized management of SB in this population should be considered, emphasizing the management of risk factors.

Cerebral palsy: Oral manifestations and dental management

Cerebral palsy is a set of non-progressive neuromuscular disorders caused by defects in the developing fetal brain. Its prevalence is about 2:1000. Although CP does not directly result in any particular oral abnormalities, some conditions are more prevalent or severe in CP patients than in the general population. The purpose of a paediatric dentist is to promote overall oral health wellness and to motivate parents and other primary caregivers to practice good oral hygiene at home. The aim of this article is to provide a general overview of dental health issues that affect people with CP and to analyze key preventative and practical management techniques for this common comorbidity.

Factors associated with dental caries experience of Thai preschool children with cerebral palsy

AIM

To investigate the factors association with dental caries experience in the primary dentition of Thai preschool children with cerebral palsy.

METHODS AND RESULTS

A cross-sectional study was conducted among sixty Thai preschool children with cerebral palsy, aged 3-6 years old. Caries experience was determined by identifying decayednon-cavitated and cavitated lesion, missing, and filled surfaces of deciduous teeth(dmfs). Sociodemographic data, CP motor types, dietary habits, oral health behaviors and dental plaque index were collected. Multiple linear regression analysis was carried out to identify the strength of the association between factors and dental caries experience. The prevalence of dental caries was 91.66%. The average dmfs was 20.30 ± 21.63 surfaces/individual. The multiple linear regression indicated that dmfs was significantly associated with snacking carbohydrate between meals more than two times/day (β ± SE = 0.372 ± 0.125; p = 0.004), spastic type of cerebral palsy (β ± SE = 0.309 ± 0.124; p = 0.015) and one-time daily tooth brushing (β ± SE = 0.306 ± 0.124; p = 0.017).

CONCLUSIONS

Nine out of 10 preschool children with CP experienced dental caries. Spastic type of CP had more risk to develop dental decay. Caries prevention for preschool children with CP should emphasis on controlling the frequency of carbohydrate snack no more than two times/day and reinforcing tooth brushing at least twice daily.

Risk Factors for Dental Caries Experience in Children and Adolescents with Cerebral Palsy-A Scoping Review

Cerebral palsy is a developmental motor disorder which has far-reaching impacts on oral health. This scoping review examined the extent of research undertaken regarding the risk factors affecting dental caries experience in children and adolescents with cerebral palsy. Data were obtained from the electronic databases Web of Science and PubMed, using 10 search strings, for studies published between 1983 and 2018. Eligible studies were required to have investigated caries in children under 18 with cerebral palsy, as well as be written in English. 30 papers published were identified for inclusion in the review. These included 23 cross-sectional, 6 case-control, and 1 longitudinal study. Studies were categorized into six domains of risk factors: socioeconomic status (SE); cerebral palsy subtype (CPS); demographics (D); condition of oral cavity (OC); dental habits (DH); nutrition and diet (ND). This review was conducted and reported in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. The most significant risk factors were caregiver-related education levels, oral health literacy, and sugar intake; this underlines the important role of special education and dental awareness in reducing dental caries incidence in CP children. Other factors showed divergent findings, highlighting the need for standardization and culturally specific studies in future literature.

At-Home Orthodontic Treatment for Severe Teeth Arch Malalignment and Severe Obstructive Sleep Apnea Syndrome in a Child with Cerebral Palsy

Children with cerebral palsy typically have severe teeth arch malalignment, causing swallowing and respiration dysfunction. Malalignment in cerebral palsy, especially in children, worsens dysphagia and respiratory disorders; sometimes, it is also noted with obstructive sleep apnea. However, no study has reported on the improvement in obstructive sleep apnea after at-home orthodontic treatment in children with cerebral palsy. We herein present a pediatric case of cerebral palsy wherein obstructive sleep apnea improved with at-home orthodontic treatment for malalignment. We administered at-home orthodontic treatment to a 15-year-old boy with quadriplegia, due to spastic-type cerebral palsy, having no oral intake, obstructive sleep apnea, and teeth arch malalignment. After treatment, a decline in the severity of sleep apnea was observed. Perioral muscle hypertension and oral intake difficulties cause maxillary protrusion, narrowed teeth arch, and tilting of teeth in children with cerebral palsy. We expanded the oral cavity volume by orthodontic treatment to relieve muscle hypertension and correct the tongue position, thereby remarkably improving obstructive sleep apnea. Our findings suggest that at-home orthodontic treatment for malalignment effectively improves perioral muscle hypertension, glossoptosis, and obstructive sleep apnea.

Bruxism in children and adolescents with cerebral palsy

This study aims to summarize the existing evidence from primary studies in order to answer the following question: "are children and adolescents with cerebral palsy (CP) frequently affected by bruxism?". For such, databases Web of Science, Medline (via PubMed), Lilacs, SciELO, Scopus and Wiley Online Library were used, with the keywords “Cerebral Palsy” and “Bruxism” alone and in combination, without the restriction of the publication date. The search included all articles published until May 2020. A total of 229 publications were found, of which 12 were selected, after careful analysis. Retrospective data analyses, cross-sectional studies and observational case-control studies published in English and with samples composed of children and/or adolescents were included. Case reports, literature reviews and studies whose sample consisted of adults-only were excluded. In the evaluated studies, bruxism was present in all samples with cerebral palsy. However, oral signs and symptoms resulting from this parafunction were reported only in three studies, in which the presence of dental wear and pain was evaluated. Therefore, bruxism in children and adolescents with cerebral palsy is a frequent oral condition, however, knowledge about the associated and risk factors for the occurrence of this problem in these patients remains limited.

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.

Oral health care and service utilisation in individuals with Rett syndrome: an international cross-sectional study

BACKGROUND

There is a dearth of literature available on the comparative oral health status of those with Rett syndrome (RTT) despite diurnal bruxism being a supportive diagnostic criterion for the disorder. This study was designed to investigate the dental experiences of individuals with RTT in terms of perceived at-home and professional dental care.

METHODS

Using data in the InterRett database, provided by English-speaking families of individuals with a confirmed MECP2 genetic mutation, the study investigated relationships between dental problems, oral care, child factors including bruxism and use of gastrostomy, and socioeconomic indicators. The study also explored relationships between dental presentations and socioeconomic, child, and family-related factors.

RESULTS

Individuals with RTT exhibiting bruxism were more likely to access dental treatment. Those who had full oral feeding had a higher incidence rate of dental treatment than those with full tube feeding. A conservative (under) estimation of the overall dental caries progression rate revealed that this may be similar to that of the normal population.

CONCLUSIONS

Drivers for dental treatment in RTT include bruxism as well as dental caries. Those who have full oral feeding experience more dental treatment than those with full tube feeding. A higher maternal education level may confer a protective effect for oral health outcomes in those with RTT. Nevertheless, families generally tended to value the importance of oral health despite reported difficulties in day-to-day mouth care.

Oral parafunction and bruxism in Rett syndrome and associated factors: An observational study

OBJECTIVES

To explore patterns of parafunction, and bruxism, and its relationships with genotype and snoring in individuals with Rett syndrome (RTT).

METHODS

Retrospective observational data of those with confirmed MECP2 mutations in the InterRett database (n = 216) were used to investigate experience of parafunctional habits, and bruxism and their relationships with genotype and snoring using multivariable linear regression.

RESULTS

The prevalence of parafunction was 98.2%. Bruxism was reported (66.2%) with the patterns mostly both diurnal and nocturnal (44.1%) and exclusively diurnal (42.7%). Compared to individuals with C-terminal deletion, individuals with p.Arg106Trp mutations were less likely to have bruxism reported (aOR = 0.15; 95% CI 0.02-0.98, p = 0.05) and those with p.Arg168* mutation were more likely to have frequent bruxism than none or occasional bruxism reported (aROR 3.4; 95% CI 1.1-10.7 p = 0.04). The relative odds of having nocturnal bruxism constantly, compared to none/occasionally, were higher among those 'always' snoring (aROR 6.24; 95% CI 2.1-18.2, p = 0.001) than those with no snoring.

CONCLUSIONS

There appeared to be genotypic association with bruxism in p.Arg168* and p.Arg106Trp mutations and association between nocturnal bruxism and frequent snoring in an international sample of individuals with RTT. Clinical significance of the high prevalence of bruxism should be highlighted in relation to difficulty communicating pain and increased dental treatment need in RTT.

Epidemiological profile of patients with disabilities undergoing dental treatment under general anesthesia

Abstract Introduction General anesthesia is commonly used in the dental treatment of people with disabilities, anxious or difficult behavior, who need complex and/or extensive treatments. Objective The aim of this study was to evaluate the epidemiological profile of patients with disabilities undergoing dental treatment under general anesthesia by the team of the Dental Unit for Patients with Special Needs of the Federal University of Sergipe. Material and method Through the analysis of 371 dental records of patients assisted between August 2002 and March 2019. Result The analysis showed that 56.1% of patients were male, the most prevalent age group was 11-20 years, and the most frequent medical conditions were intellectual disability, followed by multiple disabilities. Relative to dental procedures, in 94.1% of the patients, it was observed that 4,056 dental extractions were performed and in 52.3% of patients, 1,156 restorations were performed. In 30.2% of patients, total multiple extractions were performed. Radiographic examination was performed in 51.8% of patients. As regards the origin of patients, 58.8% were from municipalities in the state, other than the capital. Return to the service for follow-up and prevention was observed in 38.5% of patients. Conclusion There is great need for early dental intervention, with specific preventive actions for this group of patients, focusing on those from interior regions of the state.

Toothbrush deterioration and parents' suggestions to improve the design of toothbrushes used by children with special care needs

BACKGROUND

Biting objects was a parafunctional oral habit among children with special care needs. Chewing or biting toothbrushes could expedite the process of toothbrush wear. However, few studies evaluated the deterioration levels of toothbrushes used by children with special needs. This study aimed to assess the deterioration level of toothbrushes used by children with special care needs, and collect parents' feedbacks to improve the design of children's toothbrushes.

METHODS

The cross-sectional study recruited 277 children who had special care needs. Children's toothbrushing behaviors, background information, and parents' comments on toothbrushes were obtained. Toothbrush deterioration was assessed by bristle wear and bite mark scores. Higher scores indicated severe deterioration.

RESULTS

Three hundred twenty-one toothbrushes were collected. Children who used 2 to 6 toothbrushes in a 3-month period showed higher toothbrush deterioration scores than children who used a single toothbrush. Over 40% children's toothbrushes presented excessive wear. Excessive wear was associated with social skills and parents' education background. Distinct bite marks tended to exist on toothbrushes which had been used by children who showed challenging behaviors during toothbrushing (OR = 1.96, 95%CI1.15-3.32, p < 0.05). Approximately 27% parents reported that children's toothbrushes should be modified. Parents recommended that the size of toothbrush heads, the angle of handles, and the texture/length/distribution/diameter of bristles should be adjusted. Besides, ideal toothbrushes should be able to provide verbal or visual instructions to children, motivate children to brush teeth, simplify toothbrushing procedure, and protect children who had toothbrush-biting habits.

CONCLUSIONS

Excessive wear and distinct bite marks can be found on toothbrushes that had been used by children with special care needs. Toothbrush deterioration was associated with children's social skills, toothbrushing behaviors, and parents' educational attainment. The commercially available toothbrushes should be modified to meet the additional needs of young children.

Prevalence of Malocclusions and Associated Factors inBrazilian Children and Adolescents with CerebralPalsy: A Multi-Institutional Study

Background

To assess the prevalence and factors associated with malocclusions in children and adolescents with cerebral palsy (CP).

Methods

The study included 134 subjects with CP aged 2-18 years enrolled in six rehabilitation institutions and their caregivers, which provided demographic, systemic, and behavioral data. A calibrated researcher held oral examinations with record of the following malocclusion indexes, DAI and DMFT. Poisson regression analysis was used (α < 0.05).

Results

About 85.8% (n = 115) of patients had malocclusion. In deciduous and mixed dentition (n = 99), increased overjet (75.8%), open bite (51.5%), posterior cross bite (19.2%), and anterior cross bite (3.0%) were identified. Increased overjet was associated with the age group of 2-5 years and mild communication impairment. Anterior open bite was more common in children who underwent tongue interposition, lip interposition, and pacifier sucking. Communication skills, mouth breathing, and tongue interposition were associated with posterior cross bite. Severe malocclusions (DAI > 30) were observed in 88.6% of patients with permanent dentition (n = 35) and were associated with liquid diet consistency and finger sucking.

Conclusion

The prevalence of malocclusion in individuals with CP was high and associated with demographic, behavioral, and systemic factors.

Oral and maxillofacial conditions, dietary aspects, and nutritional status of children with congenital Zika syndrome

OBJECTIVE

The aim of this study was to investigate oral and maxillofacial outcomes in children with congenital Zika syndrome (CZS) and the presence of nonnutritive sucking habits, functional habits, and features related to breastfeeding and nutrition of these children.

STUDY DESIGN

We conducted a cross-sectional study with 45 children with CZS and 50 healthy controls in Sergipe state, Brazil, from February 2018 to June 2018. Demographic and clinical data, including breastfeeding and feeding data, were obtained for each child. Additionally, oral and maxillofacial evaluation was performed.

RESULTS

Low weight (prevalence rate [PR] 8.33; 95% confidence interval [CI] 2.02-34.45), nonexclusive breastfeeding up to 6 months (PR 1.56; 95% CI 1.18-2.08); mouth breathing (PR 3.46; 95% CI 1.83-6.52); difficulty in swallowing (PR 6.00; 95% CI 2.53-14.25); and excessive salivation (PR 4.81; 95% CI 2.18-10.62) were more frequent in children with CZS. Children with CZS were more likely to have abnormal insertion of the upper labial frenulum (PR 7.04; 95% CI 2.23-22.20); ogival palate (PR 3.70; 95% CI 1.63-8.40), dental enamel defects (PR 2.22; 95% CI 1.05-4.69); and delayed dental eruption (PR 8.89; 95% CI 1.16-68.32) compared with healthy children.

CONCLUSIONS

Children with CZS had a higher frequency of problems related to breastfeeding, low weight, and oral and maxillofacial abnormalities compared with healthy children.

Cerebral palsy and bruxism: Effects of botulinum toxin injections-A randomized controlled trial

Objective

Cerebral palsy (CP) includes disturbances in muscular control caused by perinatal brain injury. Masticatory muscle involvement hampers functions such as chewing and talking. Bruxism and temporomandibular disorders are overrepresented. Neuromuscular blocks with botulinum toxin type A (BTX‐A) may alleviate problems due to muscular hyperactivity. The aim was to evaluate masticatory muscle BTX‐A injections in subjects with CP and bruxism.

Methods

A prospective, parallel, randomized, placebo‐controlled, and double‐blind trial in 12 patients with CP was performed. End points were alterations in objective and subjective oral capacities after two BTX‐A or corresponding placebo injections. Matched, healthy references were also evaluated.

Results

The reference group demonstrated stronger and more efficient oral functions compared with the CP group. Subjective and objective oral capacities appeared to vary considerably between CP patients and also over time in this patient group and were poorly correlated. No significant effect of BTX‐A compared with placebo on outcome variables was observed at group level, but continued treatment with BTX‐A was requested by the majority of the patients.

Conclusion

The evidence is unable to support the use of BTX‐A for the treatment of affected masticatory muscles in CP, but the findings are inconclusive in certain respects. Larger, more homogeneous groups of CP patients need to be evaluated in future trials.

A comparative study on oral health status in Greek preschool children with neurodevelopmental disorders with movement limitations

AIM

To assess the oral health status of preschool children with neurodevelopmental disorders (NDD) in Greece and compare it to that, of healthy children of the same age.

METHODS AND RESULTS

The sample consisted of 146 preschool children with NDD and movement limitations attending the rehabilitation centers of ELEPAP and 165 healthy children matched for age and maternal origin. Caries prevalence, dmft index, precavitated carious lesions (WSL) prevalence Visual Plaque Index (VPI), Restorative Index (RI), Mutans Streptococci (MS) levels, saliva buffer capacity, gingival hyperplasia, tooth wear and developmental dental defects were assessed. Data were analyzed using parametric and nonparametric tests (P ≤.05). The NDD group, compared to the healthy controls, had significantly lower caries prevalence (P <.001), dmft index (P <.001), VPI (P <.001) and MS levels (P = .027), significantly higher WSL prevalence (P <.001), and visited the dentist at an older age (P <.001). Significant determinants of WSL in the NDD group was the VPI (P = .009) and the presence of MS (P <.028).

CONCLUSION

Preschool children with NDD had lower prevalence of manifested caries but higher prevalence of WSL. However, most oral health parameters need improvement for both groups indicating the need for proper early interventions especially in the NDD group.

Alterations in the primary teeth of children with microcephaly in Northeast Brazil: a comparative study

BACKGROUND

The outbreak of microcephaly between 2015 and 2017 in Brazil created an international public health emergency.

AIM

This study sought to evaluate the chronology, sequence of eruption, and the presence of anomalies amongst children with microcephaly compared with normoreactive children.

DESIGN

A comparative study of 108 children aged 0-2 years attending public services was conducted. The microcephaly group (MG; n = 54) and the nonmicrocephaly group (NMG; n = 54) were matched by age, gender, and family income at a 1 : 1 ratio. Erupted teeth and the presence of anomalies were evaluated and compared. Chi-square tests, Pearson's correlations, Fisher's exact tests, and Student's t-tests were applied (α = 0.05).

RESULTS

No between-group differences were found with regard to gender (P = 0.560) or age (P = 0.529). The MG presented with a higher percentage of alterations in eruption sequence, opacity, self-injury, and delayed eruption compared with the NMG (P < 0.05). The MG was more likely to exhibit changes in tooth eruption sequence (OR = 12.23, 95% CIs = 3.25-46.03, P < 0.001), delayed eruption (OR = 23.12; 95% CIs = 7.09-75.40, P < 0.001), and opacity (n = 12.19, 95% CIs = 1.44-103.28, P = 0.022) than the NMG.

CONCLUSION

Children with microcephaly present with greater delays in chronology, alterations in eruption sequence, and enamel defects than normoreactive children.

Factors associated with anterior open bite in children with developmental disabilities

AIM

To investigate factors associated with anterior open bite in individuals aged from 2 to 33 years with developmental disabilities.

DESIGN

This is a cross-sectional study. A total of 271 dental records were examined. The anterior open bite analyzed was determined based on clinic exam. These variables were also analyzed: gender, age, education level of mother, International Code of Diseases (ICD), mouth breathing, use of anticonvulsant drugs, hyperkinesis, pacifier use, thumb sucking, seizure, and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without anterior open bite. Variables with a p-value of < 0.25 in the bivariate analysis were incorporated into the logistic regression models.

RESULTS

Mouth breathers had a 2.60-fold (95% CI: 1.35-5.01) greater chance of exhibiting anterior open bite than nasal breathers. Pacifier users are more likely to have an anterior open bite (3.32-fold, 95% CI: 1.62-6.77). Individuals with reported involuntary movements had a 2.66-fold (95% CI: 1.26-5.63) greater chance of exhibiting anterior open bite. Users of anticonvulsants drugs had a 3.05 (95% CI: 1.57-5.92) greater chance of showing anterior open bite.

CONCLUSION

Involuntary movements, mouth breathing, using anticonvulsant drugs, and using pacifier are factors associated with anterior open bite in patients with developmental disabilities.

European Society for Paediatric Gastroenterology, Hepatology and Nutrition Guidelines for the Evaluation and Treatment of Gastrointestinal and Nutritional Complications in Children With Neurological Impairment

OBJECTIVES

Feeding difficulties are frequent in children with neurological impairments and can be associated with undernutrition, growth failure, micronutrients deficiencies, osteopenia, and nutritional comorbidities. Gastrointestinal problems including gastroesophageal reflux disease, constipation, and dysphagia are also frequent in this population and affect quality of life and nutritional status. There is currently a lack of a systematic approach to the care of these patients. With this report, European Society of Gastroenterology, Hepatology and Nutrition aims to develop uniform guidelines for the management of the gastroenterological and nutritional problems in children with neurological impairment.

METHODS

Thirty-one clinical questions addressing the diagnosis, treatment, and prognosis of common gastrointestinal and nutritional problems in neurological impaired children were formulated. Questions aimed to assess the nutritional management including nutritional status, identifying undernutrition, monitoring nutritional status, and defining nutritional requirements; to classify gastrointestinal issues including oropharyngeal dysfunctions, motor and sensory function, gastroesophageal reflux disease, and constipation; to evaluate the indications for nutritional rehabilitation including enteral feeding and percutaneous gastrostomy/jejunostomy; to define indications for surgical interventions (eg, Nissen Fundoplication, esophagogastric disconnection); and finally to consider ethical issues related to digestive and nutritional problems in the severely neurologically impaired children. A systematic literature search was performed from 1980 to October 2015 using MEDLINE. The approach of the Grading of Recommendations Assessment, Development, and Evaluation was applied to evaluate the outcomes. During 2 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation using the nominal voting technique. Expert opinion was applied to support the recommendations where no randomized controlled trials were available.

Dental health of children with cerebral palsy

Cerebral palsy (CP) is a common chronic motor disorder with associated cognitive, communicative, and seizure disorders. Children with CP have a higher risk of dental problems creating significant morbidity that can further affect their wellbeing and negatively impact their quality of life. Screening for dental disease should be part of the initial assessment of any child with CP. The objective of this article is to present an updated overview of dental health issues in children with CP and outline important preventative and practical strategies to the management of this common comorbidity. Providing adequate oral care requires adaptation of special dental skills to help families manage the ongoing health issues that may arise. As oral health is increasingly recognized as a foundation for general wellbeing, caregivers for CP patients should be considered an important component of the oral health team and must become knowledgeable and competent in home oral health practices.

Prevalence of orofacial dysfunction in cerebral palsy and its association with gross motor function and manual ability

AIM

To investigate the prevalence of orofacial dysfunction (OFD) and explore factors associated with OFD in young individuals with cerebral palsy (CP).

METHOD

We conducted a cross-sectional study on a population with CP in a Swedish county (132 individuals, mean age 14y 2mo [SD 4y 5mo], range 5-22y) using the Nordic Orofacial Test - Screening (NOT-S), Gross Motor Function Classification System (GMFCS), and Manual Ability Classification System (MACS). The NOT-S interview was completed by 129 individuals (76 males, 53 females) of whom 52 (30 males, 22 females) also agreed to complete the NOT-S examination.

RESULTS

OFD occurred in at least one NOT-S domain in about 80% of the individuals and was present in all subdiagnoses, GMFCS levels, and MACS levels. Prevalence of OFD increased with increasing levels of GMFCS and MACS from level I=55% to level V=100%. Within the 12 NOT-S domains, the prevalence of OFD varied between 19% and 69%, wherein seven of them were at least 40%: 'Drooling', 'Nose breathing', 'Chewing and swallowing', 'Face at rest', 'Oral motor function', 'Speech', and 'Facial expression' (in ascending order).

INTERPRETATION

OFD is common in CP. The use of OFD screening in health service planning would assist detection of areas in need of further evaluation.

Teeth grinding, oral motor performance and maximal bite force in cerebral palsy children

AIM

Identify whether the degree of oral motor performance is related to the presence of teeth grinding and maximal bite force values in children with spastic cerebral palsy.

METHODS

Ninety-five spastic cerebral palsy children with and without teeth grinding, according to caregivers' reports, were submitted to a comprehensive oral motor performance evaluation during the feeding process using the Oral Motor Assessment Scale. Maximal bite force was measured using an electronic gnathodynamometer.

RESULTS

The teeth grinding group (n = 42) was younger, used anticonvulsant drugs, and was more frequently classified within the subfunctional oral motor performance category. Teeth grinding subfunctional spastic cerebral palsy children presented lower values of maximal bite force. The functional groups showing the presence or absence of teeth grinding presented higher values of maximal bite force compared with the subfunctional groups.

CONCLUSION

In spastic cerebral palsy children, teeth grinding is associated with the worse oral motor performance.

Cerebral palsy: a dental update

Special and medically compromised patients present a unique population that challenges the dentist’s skill and knowledge. Providing oral care to people with cerebral palsy (CP) requires adaptation of the skills we use everyday. In fact, most people with mild or moderate forms of CP can be treated successfully in the general practice setting. This article is to review various dental considerations and management of a CP patient.

Association between anticonvulsant drugs and teeth-grinding in children and adolescents with cerebral palsy

The relation between teeth-grinding and the use of drugs acting on the central nervous system of cerebral palsy (CP) patients has not yet been described. The aim of this research was to evaluate the presence or absence of teeth-grinding (sleep and/or awake periods) in normal and in CP children and adolescents, as well as the association of teeth-grinding and use of anticonvulsant drugs. The sample consisted of 207 children and adolescents, divided into three groups: G1, individuals with CP who did not take anticonvulsant drugs; G2, individuals with CP administered medications on a regular basis; and CG, normal individuals. Logistic regression analyses were performed to evaluate the association of teeth-grinding with some variables. No significant statistical differences were observed regarding the presence or absence of teeth-grinding when G1 and G2 were compared. However, compared with the CG, a statistically significant difference was determined, with the CG showing fewer children presenting teeth-grinding (P < 0·001). Among those children/adolescents prescribed drug therapy, the barbiturate group showed a greater frequency of teeth-grinding. CP children and adolescents show a greater and significant presence of grinding of the teeth compared with normal individuals. Subjects taking barbiturate drugs showed greater presence of teeth-grinding, than those who were taking medications from the other groups of anticonvulsant drugs.

A study on the eruption timing of permanent dentition in patients with cerebral palsy

PURPOSE

This study aimed to determine the average eruption time and sequence of permanent teeth in patients with cerebral palsy (CP) and to compare the results with the established norms for Iranian subjects.

METHODS

This cross-sectional study comprised of 207 individuals with CP, 96 boys and 111 girls, ranging from 6 to 19 years. The average age at eruption of permanent teeth, excluding third molars, was given as the mean (± SD) and median in years for each gender. A table of percentiles of the eruption time was also determined. Comparisons were made using t-test at a significance level of 0.05.

RESULTS

The sequence of eruption in children with CP was almost similar to the normal. With the exception of the second premolar and the second molar, tooth eruption was advanced in girls compared with boys. There was no difference between the left and right sides of each arch. Mandibular teeth had an earlier eruption time than maxillary teeth except for the second premolar. In general, eruption times of children with CP were later (1-33 months) than those reported previously for healthy children.

CONCLUSIONS

Despite the almost similar sequence of eruption, a high tendency to delayed eruption of permanent dentition was observed in children with CP.

Oral health in preschool children with cerebral palsy: a case-control community-based study

International Journal of Paediatric Dentistry 2010; 20: 330-335 Objectives. To assess and compare the oral health status of preschool children with and without cerebral palsy (CP). Methods. Preschool children with CP (72) were recruited from 23 Special Child Care Centers in Hong Kong. An age (+/-3 months) and gender matched sample of preschool children from mainstream preschools were recruited as the control group. Dental caries status, gingival health status, tooth wear, developmental defect of enamel, malocclusion, dental trauma and oral mucosal health were assessed and compared between the two groups. Results. Significant differences in gingival health status were found between children with and without CP (mean plaque index scores, P = 0.001 and mean gingival index scores, P < 0.05). Tooth wear involving dentine was more prevalent among CP children (P < 0.001), as were evidence of anterior open-bite (P < 0.001) and oral mucosal lesions (P < 0.05). Children with and without CP had similar caries experiences (P > 0.05), prevalence of enamel defects (P > 0.05) and dental trauma (P > 0.05). Conclusions. Differences of oral health status exist among preschool children with and without CP. Preschool children fare worse in terms of gingival health, tooth wear, oral mucosal health and malocclusion.

Assessment scale of the oral motor performance of children and adolescents with neurological damages

Among the conditions that classify individuals as special needs patients are those resulting from neurological sequelae, particularly cerebral palsy (CP), which is a disorder of high prevalence. Innumerable alterations can be found in individuals with CP but the inability to control striated muscles, due to damages suffered by the central nervous system, should be emphasized. Changes in tonus, speed and strength of oral muscles, reduction of mandibular mobility amplitude and difficulty to passively seal the lips are characteristics observed in such individuals. Categorization of the individual's mastication pattern is important in order to establish diagnosis and treatment protocols and prognosis. The aim of this study was to develop an Oral Motor Assessment Scale (OMAS) and evaluate its performance in terms of construct validity and reliability in a cohort of 53 children and individuals with CP. Two dentists examined the same patients on two different occasions. Good interexaminer (kappa > 0.85) and intra-examiner (kappa > 0.90) agreement was obtained for the majority of the OMAS items. This study shows that the OMAS is an accurate and valid method of assessment of oral motor skills in children and adolescents with neurological damages.

A review of cerebral palsy for the oral health professional

Individuals who have cerebral palsy (CP) face many physical challenges throughout their lifetimes in addition to societal barriers that can have an impact on quality of life. The ability to access appropriate dental care has long been an issue for people who have disabilities. Dentists should be integral members of teams of professionals involved in optimizing the health of individuals who have CP. As with all members of this interdisciplinary team, oral health care providers should have a thorough knowledge of the medical, cognitive, and rehabilitative issues associated with CP. With this knowledge the best possible health care can be provided.

An analysis of human skeletal remains with cerebral palsy: associated skeletal age delay and dental pathologies

In 2002 the authors were asked to examine the skeletal remains of an individual with a known history of severe cerebral palsy (CP) who was 21-23 years old at death. Skeletal age estimates of 11-15 years and dental age estimates of c. 16 years are younger than the known age of the decedent. Skeletal analysis also identified dental pathologies such as chronic tooth grinding and substantial calculus deposits. Scarce literature exists on forensic human remains cases with CP, and this study contrasts the age discrepancy and other features of this case with typical clinical characteristics of CP. A review of the CP literature suggests that delayed skeletal maturation and dental pathologies such as those observed in this case are indicative of complications related to CP. This article may alert future investigators to some of the osteological signs of CP and the probability that age indicators may be misleading.
