Introduction: rheumatoid arthritis is part of the group of autoimmune diseases with considerable incidence in the population. It is characterized by the affection of the joints of the body that suffers from it; most frequently the temporomandibular joint is affected due to the articular complex that it presents; among the signs and symptoms that we can commonly find in patients with this type of disease are joint clicks or noises, orofacial pain, loss or impossibility of jaw movement and anatomical changes located in the temporomandibular joint area. Objective: to describe the consequences that rheumatoid arthritis triggers on the temporomandibular joint and how it is for the dentist to manage these patients in consultation, to evaluate the treatments for each case on a correct diagnosis. Material and methods: a bibliographic review of recent articles on the subject was carried out, using search engines such as SciELO, Elsevier and PubMed, with 30 sources selected in English and Spanish. Results: this autoimmune disease is characterized by affecting multiple joints of the human body symmetrical and bilaterally including the TMJ which leads to the risk of developing TMD. It is important to know the methods to make a correct diagnosis of the TMJ of the patient with RA in order to offer a conservative treatment. Conclusions: the temporomandibular disorders that trigger rheumatoid arthritis are conditions that should be considered for the proper management of the patient with this condition, understanding and supporting a clinical diagnosis is of vital importance to give the patient an adequate treatment depending on the degree of complexity in which each individual is; knowing the proper management and directing the patient to a better quality of life is key in the day-to-day dental practice (AU)

Research progress in effect of chewing-side preference on temporomandibular joint and its relationship with temporo-mandibular disorders / 浙江大学学报·医学版

Chewing-side preference is one of the risk factors for temporomandibular disorders (TMD), and people with chewing-side preference is more prone to have short and displaced condyles, increased articular eminence inclination and glenoid fossa depth. The proportion of TMD patients with chewing-side preference is often higher than that of the normal subjects. Clinical studies have shown a strong correlation between chewing-side preference and TMD symptoms and signs; and animal studies have shown that chewing-side preference can affect the growth, development, damage and repair of the mandible. After long-term unilateral mastication, changes in the stress within the joint cause the imbalance of temporomandibular joint (TMJ) structural reconstruction, the transformation and even destruction of the fiber structure of masticatory muscle, resulting in uncoordinated movement of bilateral muscles. The joint neurogenic diseases caused by the increase of neuropeptide substance P and calcitonin-gene-related-peptide (CGRP) released locally by TMJ may be the mechanism of TMD. This article reviews the research progress of the influence of chewing-side preference on the structure of TMJ, the relationship between chewing-side preference and TMD, and the related mechanisms.

Association of bruxism and anxiety symptoms among military firefighters with frequent episodic tension type headache and temporomandibular disorders / Associação de bruxismo e sintomas de ansiedade em bombeiros militares com cefaleia do tipo tensional episódica frequente e desordens temporomandibulares

ABSTRACT Objective To assess the presence of bruxism and anxiety among military firefighters with frequent episodic tension-type headache and painful temporomandibular disorders (TMDs). Methods The sample consisted of 162 individuals aged 18 to 55 years divided into four groups. Headache was diagnosed in accordance with the International Classification of Headache Disorders-III. The Research Diagnostic Criteria for Temporomandibular Disorders questionnaire was used to classify TMDs and awake bruxism; sleep bruxism was diagnosed in accordance with the International Classification of Sleep Disorders-3; and anxiety was classified using the Beck Anxiety Inventory. In statistical models, a significance level of 95% was used. The chi-square test was used to assess anxiety. Results Associations were found among frequent episodic tension-type headache, painful TMDs, awake bruxism and anxiety (p < 0.0005). Sleep bruxism was not a risk factor (p = 0.119) except when associated with awake bruxism (p = 0.011). Conclusion Anxiety and awake bruxism were independent risk factors for developing frequent episodic tension-type headache associated with painful TMDs; only awake bruxism was a risk factor for frequent episodic tension-type headache with non-painful TMDs.

RESUMO Objetivo Avaliar a presença de bruxismo e sintomas de ansiedade entre bombeiros militares com cefaleia do tipo tensional episódica frequente (CTTEF) e desordens temporomandibulares Dolorosas (DTMs). Métodos A amostra foi composta por 162 indivíduos com idade entre 18 e 55 anos divididos em quatro grupos. A CTTEF foi diagnosticada de acordo com o ICHD-III. O RDC / TMD foi usado para classificar as DTMs e o bruxismo acordado; o bruxismo do sono foi diagnosticado de acordo com o ICSD-3; e a ansiedade foi classificada usando o Inventário de Ansiedade de Beck. Nos modelos estatísticos, utilizou-se um nível de significância de 95%. O teste Qui-quadrado avaliou a ansiedade. Resultados Associações foram encontradas entre CTTEF, DTMs dolorosas, bruxismo diurno e ansiedade (p < 0,0005). O bruxismo do sono não foi fator de risco (p = 0,119), mas quando associado à atividade diurna (p = 0,011). Conclusão Ansiedade e bruxismo diurno foram fatores de risco independentes para o desenvolvimento de CTTEF associado a DTMs dolorosas. Apenas o bruxismo diurno foi fator de risco para CTTEF com DTMs não dolorosas.

Temporomandibular joint function 10-15 years after mandibular setback surgery and six weeks of intermaxillary fixation

Abstract Intermaxillary fixation (IMF) is a classic method for immobilization of the mandible after mandibular fractures and corrective surgery. However, it has been suggested that IMF may be a risk for developing temporomandibular joint (TMJ)-related symptoms, especially when applied for longer periods. Objective: To evaluate the clinical function of TMJs and masticatory muscles 10-15 years after mandibular setback surgery and subsequent six weeks of IMF. The patients' self-reported TMJ and masticatory muscle symptoms were also addressed. Methodology: Thirty-six patients (24 women and 12 men) treated with intraoral vertical ramus osteotomies and subsequent six weeks of IMF, underwent a clinical examination of TMJs and masticatory muscles 10-15 years after surgery and completed a five-item structured questionnaire reporting subjective TMJ-related symptoms. Mean age by the time of clinical examination was 34.1 years (range 27.2-59.8 years). The clinical outcome was registered according to the Helkimo clinical dysfunction index. Descriptive and bivariate statistics were performed and level of significance was set to 5%. Results: Mean maximum unassisted mouth opening 10-15 years after surgery was 50.1 mm, (range 38-70 mm, SE 1.2), statistically significantly greater in men compared to women (p=0.004). Mean Helkimo dysfunction group was 1.5 (range 1-3, SE 0.10). Eighty-one percent experienced pain on palpation in either the masseter muscle, temporal muscle or both, and 31% experienced pain when moving the mandible in one or more directions. Thirty-one percent reported pain from palpating the TMJs. In the questionnaire, none reported to have pain during chewing or mouth opening on a weekly or daily basis, but 22% reported difficulties with maximum opening of the mouth. Conclusion: Ten to fifteen years after mandibular setback surgery the patient's mandibular range of movement is good. Despite clinically recognizable symptoms, few patients reported having TMJ- or masticatory muscle-related symptoms in their daily life.

Temporomandibular joint disc displacement with reduction: a review of mechanisms and clinical presentation

Abstract Disc displacement with reduction (DDWR) is one of the most common intra-articular disorders of the temporomandibular joint (TMJ). Factors related to the etiology, progression and treatment of such condition is still a subject of discussion. This literature review aimed to address etiology, development, related factors, diagnosis, natural course, and treatment of DDWR. A non-systematic search was conducted within PubMed, Scopus, SciELO, Medline, LILACS and Science Direct using the Medical Subjective Headings (MeSH) terms "temporomandibular disorders", "temporomandibular joint", "disc displacement" and "disc displacement with reduction". No time restriction was applied. Literature reviews, systematic reviews, meta-analysis and clinical trials were included. DDWR is usually asymptomatic and requires no treatment, since the TMJ structures adapt very well and painlessly to different disc positions. Yet, long-term studies have shown the favorable progression of this condition, with no pain and/or jaw locking occurring in most of the patients.

Temporomandibular disorder: otologic implications and its relationship to sleep bruxism / Disfunção temporomandibular: implicações otológicas e sua relação com o bruxismo do sono

Abstract Introduction: Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation of temporomandibular disorder. That condition can result in pain otologic symptoms. Objective: The aim of the present study was to investigate the relationship between temporomandibular disorder and both otologic symptoms and bruxism. Methods: A total of 776 individuals aged 15 years or older from urban areas in the city of Recife (Brazil) registered at Family Health Units were examined. The diagnosis of temporomandibular disorder was determined using Axis I of the Research Diagnostic Criteria for temporomandibular disorders, addressing questions concerning myofascial pain and joint problems (disk displacement, arthralgia, osteoarthritis and osteoarthrosis). Four examiners had previously undergone training and calibration exercises for the administration of the instrument. Intra-examiner and inter-examiner agreement was determined using the Kappa statistic. Individuals with a diagnosis of at least one of these conditions were classified as having temporomandibular disorder. The diagnosis of otologic symptoms and bruxism was defined using the same instrument and a clinical exam. Results: Among the individuals with temporomandibular disorder, 58.2% had at least one otologic symptom and 52% exhibited bruxism. Statistically significant associations were found between the disorder and both otologic symptoms and bruxism (p < 0.01 for both conditions; OR = 2.12 and 2.3 respectively). Otologic symptoms and bruxism maintained statistical significance in the binary logistic regression analysis, which demonstrated a 1.7 fold and twofold greater chance of such individuals have temporomandibular disorder, respectively. Conclusion: The logistic regression analysis demonstrated strong associations between the disorder and both otologic symptoms and bruxism when analyzed simultaneously, independently of patient age and gender.

Resumo Introdução: A disfunção temporomandibular é um termo que engloba vários problemas clínicos que afetam os músculos da mastigação, a articulação temporomandibular e estruturas associadas. Esse distúrbio tem uma etiologia multifatorial, com hábitos parafuncionais orais considerados um importante cofator. Entre esses hábitos, o bruxismo do sono é considerado um agente causador envolvido no desenvolvimento e/ou na perpetuação de disfunção temporomandibular. Esse problema pode resultar em sintomas otológicos dolorosos. Objetivo: Investigar a relação entre disfunção temporomandibular e os sintomas otológicos e bruxismo. Método: Foram examinados 776 indivíduos com idade igual ou superior a 15 anos de áreas urbanas da cidade de Recife (Brasil) registrados nas Unidades de Saúde da Família. O diagnóstico da disfunção foi determinado utilizando o Eixo I dos Critérios de Diagnóstico de Pesquisa para Distúrbios Temporomandibulares, abordando questões relativas a dor miofascial e problemas articulares (luxação discal, artralgia, osteoartrite e osteoartrose). Quatro examinadores foram treinados para a administração do instrumento. A concordância intraexaminador e interexaminador foi determinada usando a estatística Kappa. Os indivíduos com diagnóstico de pelo menos uma dessas condições foram classificados como tendo disfunção temporomandibular. O diagnóstico de sintomas otológicos e bruxismo foi definido utilizando o mesmo instrumento de diagnóstico e exame clínico. Resultados: Entre os indivíduos com a disfunção, 58,2% apresentaram pelo menos um sintoma otológico e 52% apresentaram bruxismo. Foram encontradas associações estatisticamente significativas entre a disfunção temporomandibular e ambos os sintomas otológicos e bruxismo (p < 0,01 para ambos os problemas, OR = 2,12 e 2,3, respectivamente). Os sintomas otológicos e o bruxismo mantiveram significância estatística na análise de regressão logística binária, o que demonstrou uma probabilidade de 1,7 e 2 vezes maior chance de que esses indivíduos tenham disfunção temporomandibular, respectivamente. Conclusão: A análise de regressão logística demonstrou associações fortes entre disfunção temporomandibular e sintomas otológicos e bruxismo quando analisados simultaneamente, independentemente da idade e do sexo do paciente.

Trastornos temporomandibulares en la infancia: bruxismo de sueño y compromiso de atm en artritis idiopática juvenil / Temporomandibular disorders in childhood: sleep bruxism and temporomandibular joint involvement in juvenile idiopathic arthritis

Los trastornos temporomandibulares (TTM) corresponden a un grupo de condiciones musculoesqueletales y neruromusculares que involucran las articulaciones temporomandibulares (ATM), los músculos masticatorios y todos los tejidos asociados. La etiología de los TTM es considerada multifactorial, siendo el bruxismo de sueño (BS) uno de muchos factores asociados con TTM dolorosos. Tanto los TTM como el BS se presentan en adultos y niños y actualmente es sabido que la etiopatogenia de ambos no difiere de acuerdo a la edad. Las ATM son articulaciones sinoviales que pueden verse afectadas por diversos TTM o por condiciones sistémicas como la artritis idiopática juvenil (AIJ). La ATM está involucrada en un 40% de los pacientes con AIJ, siendo subestimada debido a que clínica-mente se manifiesta con poco dolor. En el presente artículo se revisarán los conceptos de TTM y BS en niños, así como también la manifestación de la AIJ en el territorio orofacial, entregando una aproximación de su etiopatogenia, identificación y manejo.

Temporomandibular disorders (TMD) encompass a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joints (TMJ), the masticatory muscles, and all associated tissues. TMD's etiology is considered to be mul-tifactorial, were sleep bruxism (SB) is one of many causes of painful TMD. TMD and SB can present in adults and children and the etiology does not differ regarding age.TMJ are synovial joints that can be affected by many TMD as well as systemic conditions such as juvenile idiopathic arthritis (JIA). TMJ are involved in 40% of patients with JIA, which is usually underestimated because of its painless presentation.This article will review the concepts of TMD and SB in children, as well as JIA presentation in the orofacial region.

Temporomandibular joint disorders as the only manifestation of juvenile idiopathic arthritis: a case report / Comprometimento da articulação temporomandibular como única manifestação da artrite idiopática juvenil: um relato de caso

ABSTRACT Juvenile idiopathic arthritis is a term used to include all chronic childhood arthritis of unknown etiology. It is characterized by chronic inflammation persisting for at least 6 weeks, beginning before 16 years of age. The characteristics present are chronic synovitis, arthralgia, impaired joint mobility in at least one joint, and erosion with destruction of cartilage and subchondral bone, that could be associated or not with systemic involvement, according to each subtype of the disease. During the pathologic process, the temporomandibular joint can be involved by the juvenile idiopathic arthritis, resulting in severe mandibular dysfunction, with higher frequency in female patients. Initially, these lesions can show minor alterations like flattening of the condyle, erosions, and evolve to severe lesions, like destruction of the head of the condyle. We report a case of male patient who had destruction of both condyles, as a result from juvenile idiopathic arthritis. Proposed mechanisms to explain the juvenile idiopathic arthritis was reviewed. In this report the patient did not have pain or inflammatory process, and the temporomandibular diseases was the only manifestation.

RESUMO Artrite idiopática juvenil é um termo usado para incluir toda artrite infantil crônica de etiologia desconhecida. É caracterizada por uma inflamação crônica, que persiste por pelo menos 6 semanas, com início antes dos 16 anos de idade. As características presentes são sinovite crônica, artralgia, mobilidade articular diminuída em pelo menos uma articulação, e erosão com destruição da cartilagem e do osso subcondral, podendo ser associada ou não com o envolvimento sistêmico, de acordo com cada subtipo da doença. Durante o processo patológico, a articulação temporomandibular pode ser envolvida pela artrite idiopática juvenil, resultando em disfunção mandibular severa, com maior frequência em pacientes do sexo feminino. Inicialmente, estas lesões podem mostrar pequenas alterações, como achatamento do côndilo e erosões, e evoluir para lesões graves, como a destruição da cabeça do côndilo. Relatou-se o caso de um paciente do sexo masculino, que apresentou destruição de ambos os côndilos, como resultado da artrite idiopática juvenil. Os mecanismos para explicar a artrite idiopática juvenil foram revisados na literatura. Neste relato de caso, o paciente não apresentou dor e nem processo inflamatório, sendo o comprometimento da articulação temporomandibular a única manifestação.

Is playing string or wind musical instruments a risk factor for temporomandibular dysfunction? a systematic review

AIM. medical problems specifically affecting professional musicians are commonly mentioned in the literature. the present study is aimed to evaluate, through a systematic review, the possible association between the practice of string with bow and wind musical instruments and the occurrence of temporomandibular dysfunction (TMD). METHODS. the search for articles was conducted in PubMed/ Medline, Web of Science, Scopus, Lilacs, Cochrane Library, and Open Gray databases, and there was no restriction on language or date of publication. the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. the MeSH terms used were: "music"; "temporomandibular joint"; "temporomandibular joint disorders"; "temporomandibular joint dysfunction syndrome"; and "occupational diseases". cross-sectional studies, case-control, cohort and clinical trials were included that involved the practice of string with bow and wind musical instruments and the occurrence of temporomandibular dysfunction (TMD). articles were previously selected by title and abstract. qualitative evaluation was done through the Newcastle-Ottawa scale. RESULTS. the literature search identified 732 studies, of which 10 met the inclusion criteria, nine of them cross-sectional studies and one a clinical intervention study. the TMD prevalence ranged from 47.0 percent to 89.0 percent. recruitment of participants took place in professional schools and orchestras, and in bands of professional musicians. all studies reported associations between TMD and the practice of musical instruments, and violinists presented higher prevalence rates when compared to other instrument groups. CONCLUSION. all studies pointed to a possible association between TMD and the practice of string and wind musical instruments. more longitudinal and clinical trials studies are needed to verify any possible interrelationship.

Psychological stress associated with aphthous ulcers and temporomandibular disorders

Objective: To assess the prevalence of stress as an etiological factor for aphthous ulcers and temporomandibular disorders

Study Design: Cross sectional descriptive study

Place and Duration of Study: Armed Forces Institute of Dentistry Rawalpindi, from Oct 2015 to May 2016

Material and Methods: Two groups of patients were selected. Group I included 119 patients presenting with Aphthous Ulcers while group II had 64 subjects with complaints of temporomandibular disorders [TMDs]

After a thorough history, Hospital Anxiety and Depression Scale [HADS] was used to assess stress in the patients. A HADS-A score of 7 was taken as significant anxiety while a HADS-D score of 7 depicted significant depression

Both groups were then subjected to laboratory examinations. Serum cortisol levels were assessed for both groups while Serum Folate, Ferritin and Vitamin B12 level for group I only. Data were analyzed using SPSS version 21 to calculate descriptive statistics including mean and standard deviations as well as frequencies and percentages

Relationship between HADS score and serum cortisol levels was assessed using Pearson's correlation coefficient

A p-value<0.05 was considered significant

Results: For TMDs, 53 [82.8%] patients were found positive for stress while for aphthous ulcers, 61 [51.3%] were positive for stress. The correlation between HADS score and serum cortisol levels was found significant for both groups at a p=<0.001

Conclusions: Patients showed a high prevalence of stress as an etiological factor for aphthous ulcers and temporomandibular disorders in a local setting

Salivary stress biomarkers and anxiety symptoms in children with and without temporomandibular disorders

Abstract The etiology of temporomandibular disorders (TMD), which are considered as a heterogeneous group of psychophysiological disturbances, remains a controversial issue in clinical dentistry. This study aimed to evaluate whether the salivary alpha-amylase (sAA), cortisol levels, and anxiety symptoms differ between children with and without TMD. Initially, 316 young subjects were screened in public schools (nonreferred sample); 76 subjects aged 7-14 years were selected and comprised the TMD and control groups with 38 subjects each matched by sex, age, and the presence/absence of sleep bruxism. Four saliva samples were collected: upon waking, 30 min and 1 h after awakening (fasting), and at night (at 8 PM) on 2 alternate days to examine the diurnal profiles of cortisol and sAA. Anxiety symptoms were screened using the Multidimensional Anxiety Scale for Children (MASC-Brazilian version). Shapiro-Wilk test, Student's t-test/Mann-Whitney U test, and correlation tests were used for data analysis. No significant differences were observed in the salivary cortisol area under the curve (AUCG mean ± SD = 90.22 ± 63.36 × 94.21 ± 63.13 µg/dL/min) and sAA AUCG (mean ± SD = 2544.52 ± 2142.00 × 2054.03 ± 1046.89 U/mL/min) between the TMD and control groups, respectively (p > 0.05); however, the clinical groups differed in social anxiety domain (t = 3.759; CI = 2.609, 8.496), separation/panic (t = 2.243; CI = 0.309, 5.217), physical symptoms (U = 433.500), and MASC total score (t = −3.527; CI = −23.062, −6.412), with a power of the test >80% and large effect size (d = 0.80), with no significant correlation between the MASC total score, cortisol, and sAA levels. Although children with TMD scored higher in anxiety symptoms, no difference was observed in the salivary stress biomarkers between children with and without TMD.

Prevalencia de maloclusiones asociadas a trastornos temporomandibulares (TTM): análisis fotográfico / Prevalence of temporomandibular disorders (TMD) associated malocclusions: a photographic analysis

Los trastornos temporomandibulares (TTM) son alteraciones del funcionamiento del sistema estomatognático. Tienen etiologíamultifactorial y sintomatología variada. El objetivo del trabajo fue determinar la prevalencia de maloclusiones que se consideran asociadasal desarrollo de TTM en pacientes pre-ortodóncicos. Se analizaron 261 estudios fotográficos iníciales de pacientes entre 11 y 45 años, deambos sexos, que ingresaron a la Cátedra de Ortodoncia de la Facultad de Odontología de la Universidad de Buenos Aires (FOUBA). Se determinó la presencia o ausencia de las siguientes maloclusiones asociadas a TTM (MATTM): mordida invertida posteriorunilateral (MIPU), mordida invertida posterior bilateral (MIPB), mordida en tijera (MT), mordida invertida anterior (MIA), mordida abierta anterior (MAA) y mordida profunda (MP). De los 261 pacientes, se registraron 51(19,54 por ciento) sin MATTM, 154 pacientes(59 por ciento) presentaron al menos una MATTM, 52 pacientes (19,92 por ciento) presentaron dos MATTM, 3 pacientes (1,15 por ciento) presentaron tres MATTM y 1 paciente (0.39 por ciento) cuatro MATTM, 72 pacientes(27.58 por ciento) presentaron mordida invertida uni lateral (MIUL), 70 pacientes (26.82 por ciento) presentaron M.P, 46 pacientes (17.62 por ciento) presentaron MIA, 38 pacientes(14.55 por ciento) presentaron MAA, 33 pacientes (12.64 por ciento) presentaron MIBL y 12 pacientes (4.59 por ciento) presentaron MT. Se concluye que es importante realizar un minucioso examen clínico para evaluar la presencia de TTM previamente al tratamiento ortodóncico, ya que sólo el 19,54 por ciento de lospacientes evaluados no registró mal oclusiones asociadas a TTM, mientras que el 59 por ciento presentó al menos una. La maloclusión a pesar de que solo es uno de los factores etiológicos dentro de la etiología multifactorial del desarrollo de TTM, es importante tenerla en cuenta y darle una solución, idealmente de manera interdisciplinaria.

Temporomandibular disorders (TMD) are pathologies of the function of the stomatognathic system. They have a multifactorial etiologyand diverse symptomatology. The aim of the study was to determine the prevalence of malocclusions that are considered associated withTMD development in pre-orthodontic patients. A total of 261 initial photographic diagnostic studies were analyzed; these comprisedpatients between the ages of 11 and 45 from the Department of Orthodontics, FOUBA. The presence and absence of the followingTTM (MATTM) associated malocclusions was analyzed detected: unilateral posterior Crossbite (UPC), bilateral posterior Crossbite(BPC), scissor bite (SB), anterior Crossbite (AC), anterior open bite (AOB) and deep bite (DB). The findings in the 261 patientstreated were: 51 patients (19, 54%) presented MATMD, 154 patients (59%) presented at least one MATTM, 52 patients (19,92%)presented two MATTMs, 3 patients (1,15%) presented three MATTMs and 1 patient (0,39%) presented four MATTMs, 72patients (27,58%) presented IUPO, 70 patients (26,82%) presented DB, 46 patients (17,62%) presented (AC), 38 patients(14,55%) presented AOB, 33 patients (12,64%) presented BPC and 12 patients (4.59%) presented SB. It is concluded that it isimportant to carry out a thorough clinical examination to evaluate the presence of TMD prior to orthodontic treatment, as only 19,54%of the patients treated showed no malocclusions associated with TMD, while 59% presented at least one. Although malocclusions are onlysome of the etiological factors in the multifactorial etiology of TMD development, it is important to take them into account and provide asolution for them, ideally an interdisciplinary solution.

La artritis reumatoidea juvenil y su influencia en la alteración de desarrollo de la mandíbula / Juvenile rheumatoid arthritis and its influence on the alteration of jaw development

La artritis reumatoidea juvenil (ARJ) es una enfermedad inflamatoria autoinmune que se presenta en niños menores de 16 años. Es de curso crónico, etiología desconocida, y afecta sobre todo las articulaciones, como la temporomandibular (ATM). El daño de la ATM puede ocasionar: alteraciones en el crecimiento facial (micrognatia), maloclusión clase II, mordida abierta anterior, desviaciones laterales, erosiones óseas, destrucción del cón-dilo, oclusión disfuncional y alteración de la estética facial, entre otras consecuencias. La posición oclusal neurofisiológica lograda por medio de elementos electrónicos, como el Transcutaneus Electrical Neural Stimulation (TENS), y mantenida por el Dispositivo Intaroral (DIO) podría posibilitar la remodelación de la cabeza del cóndilo, en pacientes en crecimiento, en los que la enfermedad se halla controlada, regulando así también la sintomatología dolorosa...

Prevalencia de bruxismo del sueño en niños y su relación con los signos de trastornos temporo-mandibulares y las parafunciones diurnas / Prevalence of sleep bruxism in children, and its relationship with signs of temporomandibular disorders and daytime oral parafunctions

El bruxismo del sueño (BS), es el acto de apretar y rechinar los dientes mientras se duerme, lo cual puede producir serias consecuencias en los niños, como el desgaste dentario y dolor muscular. El objetivo de esta investigación fue determinar la prevalencia del BS en niños, además de relacionarlo con la presencia de signos de trastornos temporomandibular (TTM) y de las parafunciones diurnas (PFD). La muestra está conformada por 369 estudiantes de 6 a 14 años. El diagnóstico de BS se basa en los criterios de inclusión de la Academia Americana de Medicina del Sueño, con reporte de los padres indicando la historia nocturna de apriete/rechinamiento dentario, presencia de PFD y antecedentes médicos. La información se complementó con examen clínico de signos de TTM y desgaste dentario. Para análisis estadístico se utilizaron las pruebas Chi-Cuadrado y Odds Ratio, con un intervalo de confianza de 95 %. La prevalencia de BS fue de 32 %. Los niños de 6 años presentan la mayor prevalencia (38 %), y los de 14 años la menor (27 %). De los individuos con BS, el 77 % presentaban signos de TTM (p<0,0001; OR: 5,4) y el 87 % presentaba PFD (p=0,0003; OR= 2,9). La prevalencia de BS, su distribución por edad y sexo, se corresponde con la evidencia científica internacional. El BS es un factor de riesgo para los TTM, aumentando las probabilidades de que las personas puedan sufrir mialgias o artralgias. En las parafunciones, el hábito de morder durante el día es común en los pacientes con BS. El tratamiento llevado a cabo durante la infancia con un diagnóstico temprano, podría ser capaz de prevenir el daño a la salud de un individuo como futuro adulto.

Sleep Bruxism (SB) is the act of grinding and clenching teeth during sleep, which could lead serious consequences in children, such a tooth wear and muscle pain. The objective of this research was to determine the prevalence of SB in children, and to relate the presence of signs of temporomandibular disorders (TMD) and daytime oral parafunctions. The sample consists of 369 students of 6­14 years old. SB diagnosis is based on the inclusion criteria of the American Academy of Sleep Medicine, with parent report indicating the history of tooth clenching/grinding, presence of awake oral parafunctions and medical history. The information was complemented by clinical examination of signs of TMD and tooth wear. For statistical analysis chi-square test and Odds Ratio Test was used, with a confidence interval of 95 %. The prevalence of SB was 32 %. Children 6 years old had the highest prevalence (38 %), and children 14 years old had less (27 %). Individuals with SB, 77 % showed signs of TMD (p<0.0001; OR= 5.4) and 87 % had daytime parafunctions (p= 0.0003; OR= 2.9). The prevalence of SB, its distribution by age and sex, corresponds to the international scientific evidence. The SB is a risk factor for TMD, increasing the probabilities that people may suffer muscle or joint aches. Daytime parafunctions are common in patients with SB. The treatment carried out during childhood with an early diagnosis, might be able to prevent damage to the health of an individual as a future adult.

Efecto de los dispositivos oclusales sobre la vía aérea en pacientes con bruxismo / Effects of occlusal splints on upper airway in bruxism therapy

Objetivo Para el manejo de los trastornos temporomandibulares y del bruxismo de sueño (BS) se ha recurrido durante años a los dispositivos oclusales rígidos superiores (DORS). Estos dispositivos podrían modificar la posición de la mandíbula induciendo una posición más posterior de la lengua y del hueso hioides, comprometiendo la permeabilidad de la vía aérea superior y agravando los trastornos respiratorios del sueño. Este trabajo tiene como objetivo evaluar el cambio de las dimensiones lineales y de área de la luz de la vía aérea faríngea en pacientes diagnosticados con BS que estén usando un DORS, mediante una telerradiografía lateral. Metodología Se reclutaron 20 pacientes del Hospital de Carabineros, de ambos sexos, diagnosticados con BS probable manejados con un DORS, a los cuales se les tomó una telerradiografía lateral sin DORS y otra con DORS sin modificar la postura para evitar distorsiones por posición craneocervical. Se analizó el área y profundidad faríngea por medio de cefalometría para medir el espacio faríngeo. Resultados Se observaron diferencias estadísticamente significativas en la disminución del área de la orofaringe (promedio: 41,2 mm2, p = 0,035) y la profundidad al nivel del gonion (promedio: 0,38 mm, p = 0,019) y la úvula (promedio: 1,38 mm, p = 0,009). No se encontró correlación entre el aumento de la dimensión vertical y las diferencias dimensionales. Conclusión Bajo las condiciones de este estudio el uso de un DORS produce una tendencia a la disminución del área y profundidad orofaríngea.

Objective The use of the superior rigid occlusal splint (SROS) has been used to management temporomandibular disorders and sleep bruxism for many years. These SROS could change the mandibular position leading to a more posterior position of the tongue and hyoids bone, and compromising the upper airway flow permeability and make sleep-breathing disorders worse. The aim of this study is to evaluate the linear and area changes of lumen in patients with sleep bruxism who are using a SROS, measured by lateral teleradiograph. Methodology The study included 20 patients, of both sexes, from the Hospital de Carabineros, Chile, who were diagnosed with probable sleep bruxism due to using and SROS. The cephalometric analysis was performed of the area and pharyngeal depth in order to measure the pharyngeal space, by obtaining a lateral teleradiograph without SROS and a second teleradiograph using SROS, at the same time, to avoid dimensional variation due to possible craniocervical positional changes. Results A statistical significance was found for oropharynx reduction (mean: 41.2 mm2, P = .035), for the gonion linear depth (mean: 0.38 mm, P = .019), and at uvula level (mean: 1.83 mm, P = .009). No correlations were found between the increasing vertical dimensions using SROS and pharyngeal spaces. Conclusion The using of a superior occlusal splint (SROS) could reduce the oropharyngeal depth and space.
