Language disorders may interfere with social integration and affectpersonal development. Beca-use the balance of the stomatognathic system can interfere with language, it is important for speech therapy and dentistry to work together, providing multidisciplinar y Healthcare. AIM: To analyze the 100 most frequently cited articles on language disorders in children and adolescents and assess the interplay with dentistry by means of a bibliometric analysis. MATERIALS AND METHOD: A search of the 100 most frequently cited articles up to December 2021 on language disorders was performed in the Web of Science Core Collection database. Four researchers extracted the data on number of citations, title, authors, country, year of publication, journals, study design, prevalent clinical conditions, and area of expertise. The analyses were performed using VOSviewer and Excel. RESULTS: The total number of citations ranged from 251 to 1,431. Four articles were cited more than 1,000 times. Bishop DVM (10 articles; 3,653 citations) and Tomblin JD (10 articles; 4,261 citations) were the most frequently cited authors. The institutions with the largest number of publications were the University of Oxford/England (11%) and the University of Kansas/USA (8%). Observational study design was the most frequent (77%). Autism spectrum disorder (18%) and dyslexia (14%) were the most broadly investigated clinical conditions. Speech-language pathology (32%) was the area of expertise with the largest number of articles, and none of the top 100 studies showed interplay with dentistry. CONCLUSION: The 100 most widely cited articles on language disorders are mostly observational, mainly address autism spectrum disorder, and are in the field of speech-language pathology No study reported interplay with dentistry.

Sleep bruxism and sleep respiratory disorders in children and adolescents: A systematic review.

OBJECTIVE: Sleep bruxism (SB) is a repetitive rhythmic and nonrhythmic activity. It can be a comorbid condition for other disorders, such as sleep breathing disorders (SBD). However, a clear causal link between these factors is yet to be established. Moreover, this relationship is even more unknown in children. Thus, this systematic review aimed to determine the relationship between SB and SBD in children and teenagers and consolidate the current knowledge about the possible association between both phenomena at the pediatric age. MATERIALS AND METHODS: Advanced searches were performed in five electronic databases with the last search updated on February 1, 2023. The methodological quality of the selected studies was analyzed using the quality assessment tool for experimental bruxism studies. RESULTS: Twenty-nine of 6378 articles were selected for detailed analyses. Most articles found a comorbid relationship between SB and SBD, though no study analyzed a temporary relationship. Due to the heterogeneity of the studies, a meta-analysis could not be performed. CONCLUSION: Despite the limitations of this systematic review, it can be concluded that there is an association between SB and SBD in children. However, the level of evidence is low.

Impact of wearing fixed orthodontic appliances on quality of life among adolescents: Case-control study.

OBJECTIVE: To investigate the impact of wearing a fixed orthodontic appliance on oral health-related quality of life (OHRQoL) among adolescents. MATERIALS AND METHODS: A case-control study (1 ∶ 2) was carried out with a population-based randomized sample of 327 adolescents aged 11 to 14 years enrolled at public and private schools in the City of Brumadinho, southeast of Brazil. The case group (n  =  109) was made up of adolescents with a high negative impact on OHRQoL, and the control group (n  =  218) was made up of adolescents with a low negative impact. The outcome variable was the impact on OHRQoL measured by the Brazilian version of the Child Perceptions Questionnaire (CPQ 11-14) - Impact Short Form (ISF:16). The main independent variable was wearing fixed orthodontic appliances. Malocclusion and the type of school were identified as possible confounding variables. Bivariate and multiple conditional logistic regressions were employed in the statistical analysis. RESULTS: A multiple conditional logistic regression model demonstrated that adolescents wearing fixed orthodontic appliances had a 4.88-fold greater chance of presenting high negative impact on OHRQoL (95% CI: 2.93-8.13; P < .001) than those who did not wear fixed orthodontic appliances. A bivariate conditional logistic regression demonstrated that malocclusion was significantly associated with OHRQoL (P  =  .017), whereas no statistically significant association was found between the type of school and OHRQoL (P  =  .108). CONCLUSIONS: Adolescents who wore fixed orthodontic appliances had a greater chance of reporting a negative impact on OHRQoL than those who did not wear such appliances.

Association between childhood dental experiences and dental fear among dental, psychology and mathematics undergraduates in Brazil.

The aim of the present study was to evaluate the association between childhood dental experiences and dental fear in adulthood among dentistry, psychology and mathematics undergraduate students. A cross-sectional study of 1,256 students from the city of Belo Horizonte, Brazil, was performed. Students responded to the Brazilian version of the Dental Fear Survey (DFS) and a questionnaire regarding previous dental experiences. Both the DFS and the questionnaire were self-administered. Association was tested using descriptive, bivariate and multivariate linear regression analysis, with a 5% significance level. Dentistry undergraduates reported lower scores than psychology (p < 0.001) and mathematics undergraduates (p < 0.05) for all three dimensions of the DFS. Negative dental experiences in childhood was associated with dimensions of Avoidance (B = 2.70, p < 0.001), Physiological arousal (B = 1.42, p < 0.001) and Fears of specific stimuli/situations (B = 3.44, p < 0.001). The reason for first visit to dentist was associated with dimensions of Physiological arousal (B = 0.76, p < 0.01) and Fears of specific stimuli/situations (B = 1.29, p < 0.01). Dentists should be encouraged to evaluate the dental fear of their patients before treatment. The DFS has been found to be an effective instrument for this purpose.

Association among stress, personality traits, and sleep bruxism in children.

PURPOSE: The purpose of this study was to determine the association among stress levels, personality traits, and sleep bruxism in children. METHODS: A population-based case control study (proportion=1:2) was conducted involving 120 7- to 11-year-olds with sleep bruxism and 240 children without sleep bruxism. The sample was randomly selected from schools in Belo Horizonte, Minas Gerais, Brazil. The following instruments were used for data collection: questionnaire administered to parents; child stress scale; and neuroticism and responsibility scales of the big five questionnaire for children. Psychological tests were administered and evaluated by psychologists. Sleep bruxism was diagnosed from parents' reports. The chi-square test, as well as binary and multivariate logistic regression, was applied for statistical analysis. RESULTS: In the adjusted logistic model, children with a high level of stress, due to psychological reactions (odds ratio=1.8; confidence interval=1.1-2.9) and a high sense of responsibility (OR=1.6; CI=1.0-2.5) vs those with low levels of these psychological traits, presented a nearly 2-fold greater chance of exhibiting the habit of sleep bruxism. CONCLUSION: High levels of stress and responsibility are key factors in the development of sleep bruxism among children.

Incidence of malocclusion between primary and mixed dentitions among Brazilian children. A 5-year longitudinal study.

OBJECTIVE: To determine the incidence of malocclusion in a 5-year follow-up of school children and verify the hypothesis that individuals with previous malocclusion are more prone to maintain the same characteristics in the transition from primary to mixed dentition. MATERIALS AND METHODS: School children, ages 8 to 11 years, participated. Inclusion criteria consisted of normal occlusion in primary dentition or subsequent malocclusions, anterior open bite and/or posterior crossbite and/or overjet measuring more than 3 mm, and that subjects had not submitted to orthodontic treatment and adenoidectomy. Data collection was based on evaluation of occlusion in school children in the actual stage of mixed dentition. Descriptive, Chi-square, and relative risk (RR) 95% confidence interval (CI) analyses were carried out. RESULTS: The greatest incidence of malocclusion was found in children with malocclusion (94.1%) when compared with those without malocclusion (67.7%) (RR  =  1.4 [1.2-1.6]; P < .001). Anterior open bite (RR  =  3.1 [1.7-5.8]), posterior crossbite (RR  =  7.5 [4.9-11.5]), and overjet greater than 3 mm (RR  =  5.2 [3.4-8.0]) in the primary dentition are risk factors for malocclusion in early mixed dentition. Spontaneous correction of the anterior open bite was confirmed in 70.1% of cases. Posterior crossbite and overjet greater than 3 mm were persistent in 87.8% and 72.9% of children. CONCLUSIONS: Malocclusion incidence was high. Individuals with previous anterior open bite, greater overjet, and posterior crossbite had greater risk of having the same characteristics in the mixed dentition.

Proposal for the teaching of the chemical control of supragingival biofilm.

The mechanical control of supragingival biofilm is accepted as one of the most important measures to treat and prevent dental caries and periodontal diseases. Nevertheless, maintaining dental surfaces biofilm-free is not an easy task. In this regard, chemical agents, mainly in the form of mouthwashes, have been studied to help overcome the difficulties involved in the mechanical control of biofilm. The aim of this paper was to discuss proposals for the teaching of supragingival chemical control (SCC) in order to improve dentists' knowledge regarding this clinical issue. Firstly, the literature regarding the efficacy of antiseptics is presented, clearly showing that chemical agents are clinically effective in the reduction of biofilm and gingival inflammation when used as adjuvant agents to mechanical control. Thus, it is suggested that the content related to SCC be included in the curricular grid of dental schools. Secondly, some essential topics are recommended to be included in the teaching of SCC as follows: skills and competencies expected of a graduate dentist regarding SCC; how to include this content in the curricular grid; teaching-learning tools and techniques to be employed; and program content.

Influence of psychosocial factors on the development of sleep bruxism among children.

BACKGROUND: Bruxism is described as an orofacial parafunction that affects both children and adults. The maintenance of the childhood habit into adulthood may compromise health. As there are few studies on this issue, there is a need for further research on sleep bruxism among children. AIM: The aim of this study was to assess the prevalence of sleep bruxism in children and the influence of psychosocial factors. METHODS: A cross-sectional study was carried out on 652 randomly selected children aged 7-10 years at public and private schools in Belo Horizonte, Brazil. The instruments used were: questionnaire for parents, Child Stress Scale, and the scales on neuroticism and responsibility from the prevalidated Big Five Questionnaire for Children. Psychological tests were administered and evaluated by psychologists. Sleep bruxism among children was reported by parents. The Social Vulnerability Index from the city hall database was used to determine the social classification of the families. The chi-squared test, binary and multivariate logistic regressions were used, with the significance level set at 5%. RESULTS: A 35.3% prevalence of bruxism was found. No association was found between bruxism and stress, gender, age, or social vulnerability. The adjusted logistic model determined that children with high levels of neuroticism (OR = 1.9, CI 1.3-2.6) and responsibility (OR = 2.2, CI 1.0-5.0) are twice as likely to have the habit of sleep bruxism when compared to those who have low levels of these personality traits. CONCLUSIONS: A high degree of responsibility and neuroticism, which are individual personality traits, are determinant factors for the development of sleep bruxism among children.
