Relação entre bruxismo, fatores oclusais e hábitos bucais

Factors associated with preschool children's sleep bruxism

OBJECTIVE

To evaluate the prevalence of sleep bruxism, related factors, and quality of life of preschool children and their families.

METHOD

The sample was 475 children between 4 and 5 years old enrolled in schools in the city of Bauru-Brazil. Parents/legal guardians answered two questionnaires, one to assess the presence of bruxism and related factors and another that was the validated Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Intraoral clinical examination was performed by two trained examiners (Kappa = 0.82) within the school environment. The data were analyzed using statistics and the Mann-Whitney, Kruskal-Wallis, and Spearman correlation coefficient. The significance level was p < 0.05.

RESULTS

The prevalence of sleep bruxism was 47.4%. The highest prevalence was related to Class I canines and marked overjet, oral habits, such as nail biting, lip biting, chewing gum, and mouth breathing. Children with agitated sleep, reports of headache, and those considered aggressive, anxious, and/or shy were also more related.Conclusion: In the studied sample, sleep bruxism prevalence was high and related to important oral and general factors. Data also indicated SB as the main factor that interfered in the OHRQoL of children and their families.

Risk factors for dysgeusia during chemotherapy for solid tumors: a retrospective cross-sectional study

PURPOSE

This study retrospectively analyzed the risk factors for transchemotherapy dysgeusia.

METHODS

Before each chemotherapy cycle, patients were routinely evaluated for the presence/severity of dysgeusia based on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 scale for adverse effects and graded as follows: 0, no change in taste; 1, altered taste with no impact on eating habits; or 2, altered taste with an impact on eating habits. Information from 2 years of evaluations was collected and patient medical records were reviewed to obtain data on chemotherapy cycle, sex, age, body mass index, body surface area, primary tumor, chemotherapy protocol, and history of head and neck radiotherapy. The X² test and multinomial logistic regression were used for statistical analysis (SPSS 20.0, p < 0.05).

RESULTS

Among 7425 total patients, 3047, 2447, and 1931 were evaluated after the first, second, and third chemotherapy cycles, respectively. One-fifth of the patients (19.0%) presented a significant loss of taste, with 1118 (15.0%) showing grade 1 dysgeusia and 442 (6.0%) showing grade 2 dysgeusia. The chemotherapy duration (p < 0.001), female sex (p < 0.001), location of the primary tumor in the uterus (p = 0.008), head and neck (p = 0.012), and testicles (p = 0.011), and use of ifosfamide (p = 0.009), docetaxel (p = 0.001), paclitaxel (p < 0.001), pertuzumab (p = 0.005), bevacizumab (p < 0.001), and dacarbazine (p = 0.002) independently increased the risk of dysgeusia. In head and neck tumors, a previous history of radiotherapy significantly increased the prevalence of dysgeusia (p = 0.017), and the use of cisplatin (p = 0.001) increased this prevalence.

CONCLUSION

Cycles of chemotherapy, sex, uterine cancer, head and neck tumors, testicular cancer, ifosfamide, docetaxel, paclitaxel, pertuzumab, bevacizumab, and dacarbazine increase the risk of dysgeusia.

FLOX (5-fluorouracil + leucovorin + oxaliplatin) chemotherapy for colorectal cancer leads to long-term orofacial neurotoxicity: a STROBE-guided longitudinal prospective study

BACKGROUND

Colorectal carcinoma (CRC) is widely treated by chemotherapy based on an intensely neurotoxic drug: oxaliplatin (OXL). We objective to evaluate prospectively the orofacial neurotoxicity during FLOX (fluorouracil + leucovorin + OXL) chemotherapy.

METHODS

So, 46 patients with CRC were prospectively evaluated during FLOX chemotherapy by 3 cycles (C) of 6 weeks (W) each. We weekly applied the orofacial section of the Acute and Chronic Neuropathy Questionnaire of Common Toxicity Criteria for Adverse Events of the National Cancer Institute of the United States of America (Oxaliplatin-specific neurotoxicity scale). Patients were asked the following concerning the severity (scores 0-5) of orofacial symptoms: jaw pain, eyelids drooping, throat discomfort, ear pain, tingling in mouth, difficulty with speech, burning or discomfort of the eyes, loss of any vision, feeling shock/pain down back and problems breathing. We summed the scores (0-50) and evaluated the clinicopathological data. Friedman/Dunn, Chi square and multinomial regression logistic tests were used (SPSS 20.0, p < 0.05).

RESULTS

There was a significant increase in sum of orofacial neurotoxicity from baseline to C1.W3, C2.W1 and C3.W5 (p < 0.001) due increase in scores of jaw pain (p < 0.001), eyelids drooping (p = 0.034), throat discomfort (p < 0.001), ear pain (p = 0.034), tingling in mouth (p = 0.015), burning/discomfort of your eyes (p < 0.001), loss of any vision (p < 0.001), feeling shock/pain down back (p < 0.001), problems with breathing (p = 0.045), but not difficulty with speech (p = 0.087). Women (p = 0.021) and young patients (p = 0.027) had significant higher prevalence of orofacial neurotoxicity.

CONCLUSIONS

FLOX-related orofacial neurotoxicity begins acutely and remains long term with increased incidence in women and younger patients.

Is there association between dental malocclusion and bruxism? A systematic review and meta-analysis

OBJECTIVES

Given that current literature largely dissociates dental malocclusion and bruxism, the objective of this study was to gather, through a systematic review, scientific evidence to support their relationship.

METHODOLOGY

This study was performed according to the PECO strategy (where P = general population; E = dental malocclusion; C = no dental malocclusion; and O = bruxism). Literature searches were conducted without language or date restrictions in the following databases: PubMed, Scopus, the Web of Science, the Cochrane Library, LILACS/BBO via VHL and the grey literature. The search strategy included Medical Subject Headings/DECs, synonyms and free terms relevant to each database, with no age restrictions applied. Once the relevant data were extracted from the articles, the Fowkes and Fulton guidelines were followed to assess the quality and risk of bias. For quantitative analysis, dental malocclusions were divided into groups according to their type in order to perform odds ratio (OR) meta-analyses with 95% confidence intervals (CI) using the Review Manager software program (Cochrane, London, UK). The level of certainty of evidence was demonstrated through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE).

RESULTS

After 1,502 studies found, 10 studies were included for qualitative analysis and nine for quantitative synthesis. Four studies presented high methodological quality. Five meta-analyses suggested a non-association between bruxism and Angle class I (OR: 1.05, 95% CI: 0.41-2.69; P = .92; I²  = 84%), Angle class II (OR: 1.49, 95% CI: 0.77-2.87; P = .23; I²  = 71%) or Angle class III (OR: 0.77, 95% CI: 0.31-1.93; P = .58; I²  = 0%). Bruxism was associated with children who did not present with a posterior crossbite (OR: 0.70, 95% CI: 0.51-0.96; P = .03; I²  = 27%) and present crowding (OR: 1.53, 95% CI: 1.03-2.26; P = .03; I²  = 0%). The GRADE analysis presented a very low quality of evidence.

CONCLUSION

Individuals who present with bruxism have a greater chance of crowding. However, bruxism is not associated with the presence of any of the other malocclusions evaluated.

Presence of oral habits and their association with the trait of anxiety in pediatric patients with possible sleep bruxism

BACKGROUND

Bruxism is a repetitive masticatory muscle activity with a multifactorial etiology , that can be associated to emotional factors.

AIM

The aim of the study is to identify the presence of oral habits (OHs) and their association with the trait of anxiety (State-Trait Anxiety Inventory for Children [STAI-C]) in pediatric patients with possible sleep bruxism (PSB).

METHODS

Children between 3 and 12 years of age with PSB reported by their parents with complete deciduous or mixed dentition were included in the present study. Sociodemographic data (SD) as well as those on OHs such as only natural (ON), artificial breastfeeding (OA) or both (NA), finger sucking (FS), pacifier use (PC), and biting nails (BN) or objects (OB) were obtained through an interview with the parents/guardians answered the Brazilian version of the STAI-C questionnaire.

STATISTICAL ANALYSIS USED

SD and OH as well as STAI-C findings were descriptively evaluated, while the associations between OH and STAI-C with PSB were evaluated using the Chi-square test (P < 0.05).

RESULTS

The final sample was 52 children (6.62 ± 1.8 years). Of these, 51.9% were males, 82.7% reported not living in social risk areas, and 21.2% were only children. Considering the OH, patients participated in ON (26.9%), OA (9.6%), and both (63.5%); 13.5% had an FS habit and 46.2% had related PC use; and 80.8% were reported to have OB biting behaviors, while 53.8% participated in BN. The STAI-C was present in 25 (48.1%) patients with PSB and was not associated with the presence of OH.

CONCLUSION

There is no association between STAI-C and OH in pediatric patients with PSB.

Orofacial myofunctional evaluation in cleft lip and palate: an integrative literature review

ABSTRACT Purpose: to identify the focus of scientific publications in the field of orofacial motricity in individuals with cleft lip and palate, as well as validated protocols used in speech and language evaluation. Methods: a study conducted using the following databases: Medline, SciELO, Lilacs and Google Scholar, through keywords including: cleft palate + cleft lip + evaluation + speech therapy + stomatognathic system + speech + phonation + chewing + swallowing + breathing + validation studies, in Portuguese and English. Results: a total of 572 articles that addressed the evaluation of the stomatognathic system was selected. The articles were published between 2012 and 2017, and examined for year of publication, subject area, focus, instrument used for evaluation, and type of study. Of these, 90 articles met the inclusion criteria, but only 5 used validated protocols. The greatest number of articles was published in 2014. The studies covered broad age groups, using subjective and objective methods, and instruments were often non-standardized. Conclusion: speech was the prevalent theme, while other orofacial functions were poorly investigated, demonstrating that studies with other approaches were lacking.

Interferência dos bicos ortodônticos e convencionais no sistema estomatognático: revisão sistemática

RESUMO Objetivo: Verificar se o tipo de bico, ortodôntico ou convencional, de chupeta e mamadeira, tem alguma influência sobre as alterações encontradas no sistema estomatognático causadas pela manutenção do hábito de sucção. Estratégia de pesquisa: Por meio de uma revisão de literatura sistemática com metanálise, realizada a partir das bases de dados Lilacs, Medline e Embase e com a ferramenta de busca Google Acadêmico™, com os seguintes descritores em português e inglês: “Má oclusão” + “Chupetas”; “Má oclusão” + “Alimentação Artificial”; “Má oclusão” + “Mamadeira”, além das palavras “Bico Ortodôntico” + “Bico Convencional”. Critérios de seleção: Foram incluídos estudos que apresentassem em seus métodos a comparação de grupos que utilizaram chupeta e/ou mamadeira com bico convencional com grupos que utilizaram o bico ortodôntico, sem delimitação temporal. Análise dos dados: A análise do artigo na íntegra foi realizada de modo sistemático, com as seguintes categorias tabelando os resultados pertinentes: objetivo, método - casuística e avaliação, resultados e conclusão. Resultados: Foram encontrados 1.041 trabalhos, período de 1969 a 2013, desses foram excluídos 848 trabalhos, devido aos critérios de exclusão, e outros 174 que eram repetições. Foram lidos na íntegra 19 trabalhos, dos quais quatro artigos atenderam aos critérios de inclusão propostos, e três trabalhos foram incluídos na metanálise. Tais resultados expressaram que não há diferenças significantes entre os bicos ortodôntico e convencional quanto às implicações no sistema estomatognático. Conclusão: Não há possibilidade de concluir a existência de diferenças quanto às consequências no sistema estomatognático ocasionadas por bicos convencionais e ortodônticos de chupetas/mamadeiras.

Prevalência de bruxismo e distúrbio do sono em deficientes visuais

INTRODUÇÃO: O termo "bruxismo" significa ranger ou apertar os dentes sem objetivos funcionais aparentes; é um distúrbio que ocorre usualmente durante o sono e geralmente está associado a microdespertares. Os deficientes visuais estão mais predispostos a apresentarem distúrbio do sono em razão de uma possível disfunção da glândula pineal, alterando a produção de melatonina, e, consequentemente, por apresentarem sintomas de bruxismo relacionado à ausência da percepção de luz. OBJETIVO: Verificar a ocorrência de bruxismo e distúrbio do sono em deficientes visuais. MATERIAIS E MÉTODOS: Amostra de conveniência com casuística de 63 voluntários com acuidade visual inferior a 0,05 (20/400) até a ausência da percepção luminosa. Foram submetidos à aplicação do Índice de Qualidade do Sono de Pittsburgh (PSQI) e do Inquérito para Diagnóstico de Bruxismo. RESULTADOS: A prevalência de bruxismo e má qualidade do sono foram, respectivamente, de 80,95% e de 85,71%. O bruxismo foi mais frequente entre aqueles com história de deficiência visual congênita (65,08%) do que entre os portadores de deficiência visual adquirida (34,92%), não sendo encontrada diferença significante quando comparados homens e mulheres. Já a ocorrência de má qualidade do sono foi similar entre portadores de deficiência visual congênita e adquirida. Foi verificada a associação positiva entre bruxismo e má qualidade do sono. CONCLUSÃO: Pôde-se verificar uma alta ocorrência de bruxismo e distúrbio do sono na população de deficientes visuais pesquisada. Este estudo tem importante contribuição epidemiológica e os seus resultados poderão ser utilizados para delinear futuras intervenções terapêuticas.

Há relação de hábitos orais deletérios com a tipologia facial e a oclusão dentária?

OBJETIVO: verificar se há predominância de hábitos orais deletérios nos diferentes tipos faciais eaprofundar o estudo da relação entre os hábitos orais deletérios e a oclusão dentária. MÉTODO: foram analisados 307 prontuários de pacientes entre 2 e 59 anos de idade de ambos os sexos, encaminhados ao ambulatório do Instituto CEFAC. Foram anotados dos prontuários os hábitos orais deletérios, oclusão dentária, tipologia facial, sexo e idade. RESULTADOS: observou-se que os hábitos com maior prevalência são: chupeta (125 indivíduos), ranger dentes (115 indivíduos) e mamadeira (102 indivíduos). Dentre as comparações estudadas, as que apresentaram diferença estatisticamente significante foram: a presença do uso da chupeta no grupo de 9 a 12 anos, quando comparado ao de 6 a 9 anos (p=0,0269); presença do hábito de ranger dentes no grupo de 3 a 6 anos quando comparado ao grupo com mais de 20 anos (p=0,0393); presença do hábito de ranger dentes no grupo de oclusão dentária classe I quando comparado ao classe III (p=0,0128) e presença de oclusão dentária classe I no sexo feminino quando comparado ao masculino (p=0,0177). CONCLUSÃO: não há relação entre os hábitos orais deletérios e a tipologia facial. Entretanto, há relação entre o hábito oral deletério de ranger dentes com a oclusão dentária Classe I de Angle.
