AIMS: To investigate whether localized sensitization of the sternocleidomastoid (SCM) muscle using nerve growth factor (NGF) would affect masseter and anterior temporalis muscle sensitivity and pain profiles. METHODS: A total of 28 healthy participants attended two sessions (T0 and T1). At T0, the maximum voluntary occlusal bite force (MVOBF), as well as pressure pain thresholds (PPT), mechanical sensitivity, and referred pain/sensations for the SCM, masseter, and temporalis muscles, were assessed. Participants also completed the Pain Catastrophizing Scale (PCS), the Pain Vigilance and Awareness Questionnaire (PVAQ), and the Neck Disability Index (NDI). After these assessments, 14 participants received an injection of NGF into the SCM, and 14 received an injection of isotonic saline solution. At T1 (48 hours postinjection), the participants were again submitted to the same evaluations. RESULTS: NGF caused significant mechanical sensitization in the SCM (P < .025), but not in the masseter or temporalis muscles (P > .208). It also caused significant increases in NDI score (P = .004). No statistically significant differences were found for MVOBF, frequency of referred pain/sensations, or questionnaire scores (P > .248). CONCLUSION: These results suggest that 48 hours after localized sensitization of the SCM, the primary response is impairment of neck function, but not jaw function.

Background: Orofacial pain has been a prevalent symptom in the worldwide population, which may cause restrictions in daily activities and, consequently, have a great impact on the well-being of affected individuals. Photobiomodulation using light sources, such as low-level laser or light emitting diodes, with different wavelengths, has been widely used in the last years, in addition to being a noninvasive, low-cost resource and reducing pain. Objective: This study aimed at evaluating the effect of photobiomodulation as a protocol treatment to prevent facial muscle discomfort after long-term clinical procedures. Methods: The volunteers were randomized and allocated as follows: laser (n = 16) and placebo (n = 16) groups, following a crossover study design. The laser parameters were as following: 786 nm wavelength, 9 J per point, and 100 mW power of 2.393 W/cm2 irradiance. The discomfort was induced by simulating a 50-min dental procedure (with bilateral mouth open), and the pain scale (assessed bilaterally), tiredness, and temperature measurement through thermography were used for analysis. Results: The results showed a significant lower pain and tiredness in the laser group. Also, the results showed a statistically significant valid temperature change between the groups at times: T1, T40, and T50. Conclusions: According to our results, photobiomodulation showed a positive effect on the face musculature in patients submitted to the treatments, reducing pain and improving the subjective perception of exertion.

PURPOSE: The aim was to evaluate the effect of four acidic beverages on the roughness (Ra) and color change (ΔEab) of two brands of artificial teeth and a heat-polymerized acrylic resin (HPAR) for use in a prosthetic base. MATERIALS AND METHODS: All materials were divided into 5 groups, according to the used acidic beverage (artificial saliva - control, red wine, orange juice, coke-based, and lemon juice-based soft drink). The immersion process was divided into two stages: T1 - immersion in the acidic solutions for 10 minutes for 14 days; T2 - after T1, the samples were immersed in grape juice for 14 days. The Ra of the samples was evaluated in a rugosimeter and the ΔEab in a spectrophotometer, before and after the immersions. The analysis of variance of one (ΔEab) and two factors (Ra) and Tukey were performed (α=.05). RESULTS: There was a statistical difference for roughness after immersion (T1) for Trilux and Tritone teeth, regardless of the acid solution. For Trilux teeth, all acid solutions increased Ra (P<.05). For Tritone teeth, only the coke-based soft drink did not statistically change Ra. Grape juice (T2) altered Ra only of artificial teeth (P<.05). The color was changed for all materials, after T1 and T2. CONCLUSION: In general, the acidic solutions changed the Ra and ΔEab of HPAR and artificial teeth after T1. The grape juice altered the roughness only of the artificial teeth, promoting a clinically acceptable color change in the materials.

OBJECTIVE: The aim of this study was to evaluate changes in pain and muscle force, and the relationship between them, in patients with muscle pain and bruxism, prior to and after treatment. METHODS: Thirty women with bruxism and myofascial pain (Ia) were included in this study. Sleep bruxism diagnosis was made based on clinical diagnostic criteria, and awake bruxism diagnosis was made by patient questionnaires and the presence of tooth wear. The diagnosis of myofascial pain was established according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD). Dentulous or partially edentulous patients (rehabilitated with conventional fixed prostheses) were included in the study according to the inclusion and exclusion criteria. The pain treatment protocol included occlusal splints, patient education, and physiotherapy for 30days. Bite force was measured using a dynamometer at the central incisor and the first molar regions on both sides. The exams were performed at baseline, after 7days, and 30days after treatment. The Wilcoxon test was used to compare patient pain level response among the periods analyzed in the study. Bite force data were submitted to two-way repeated-measures ANOVA, followed by the Tukey HSD test (p<0.05). A simple regression analysis was performed to verify the relation between pain level and bite force. RESULTS: Results revealed that there was a statistical difference in pain level over time for both muscles and sides (p<0.01). In the molar region, the bite force exhibited significantly higher values after 30days of treatment, when compared with the baseline (p<0.001). There was a correlation between pain level and bite force only for the temporal muscle in all periods analyzed (p<0.05). There was no strong correlation in the response level points to support the association of pain and bite force. CONCLUSIONS: Pain level decreased and bite force increased in the molar region after treatment. No strong correlation or dispersion in the relationship between pain levels and bite force was seen in women with myofascial pain and bruxism.

Paresthesia is defined as an alteration in local sensibility, associated with numbness, tingling, or unpleasant sensations caused by nerve lesions or irritation. It can be temporary or permanent. The treatment protocol for facial paresthesia is primarily based on the use of drugs and implant removal, which may not be completely effective or may require other risk exposure when there is no spontaneous regression. However, other therapeutic modalities such as acupuncture can be used. The aim of this study is to report a case of a patient with paresthesia of the inferior alveolar nerve and pain caused by an implant surgery performed 2 years earlier. The patient received acupuncture treatment during 4 months of weekly sessions. Six points were used: Large Intestine (LI4), Large Intestine (LI11), Stomach (ST36), Liver (LR3), Extra Head and Neck (E-HN-18), and Stomach (ST5). The visual analog scale was used before and after each session for the analysis of paresthesia and pain, together with assessment of the paresthesia by delimitation of the desensitized region of the skin and presented discomfort. Pain remission and reduction in the size of the paresthesia area occurred after four sessions.

O objetivo do presente estudo é apresentar uma revisão de literatura exemplificando alguns dos possíveis fatores etiológicos de limitação de abertura bucal e ilustrar o caso de um paciente diagnosticado com hiperplasia do processo coronoide. Foi realizada uma busca nas bases de dados PUBMED/MEDLINE, Scielo, Bireme e Google Acadêmico utilizando-se inicialmente o termo "limited mouth opening" e "limitação de abertura bucal" no mês de novembro de 2016. Além disso, foi realizada busca manual em periódicos e nas bases de dados com novas palavras-chave como disfunção temporomandibular, tétano, traumas, doenças genéticas e imitação de abertura bucal e hiperplasia do processo coronóide. Foram incluídos estudos clínicos, revisões de literatura, revisões sistemáticas e relatos de caso publicados em idioma inglês ou português. Foram descritos os aspectos relevantes sobre desordens na articulação temporomandibular, tétano, traumas e fraturas, lesões orais, neoplasias e efeito colateral de radio e quimioterapia, desordens genéticas, hiperplasia do processo coronóide. O diagnóstico da limitação de abertura bucal é complexo devido ao grande número de fatores que podem provocar o problema. Diante disso, é de suma importância que seja realizada correta anamnese e investigação minuciosa do histórico do paciente, além da realização de exames complementares, permitindo assim, que a causa do problema seja detectada e que o tratamento correto seja aplicado, por meio de abordagem multidisciplinar, melhorando a qualidade de vida e devolvendo saúde ao paciente(AU)

The objective of this study is to present a review of literature exemplifying some of the possible etiological factors of oral opening limitation and to illustrate the case of a patient diagnosed with coronoid hyperplasia. A searched was made on PUBMED / MEDLINE, Scielo, Bireme and Google Scholar databases initially using the term "limited mouth opening" and "limitação de abertura bucal" in the month of November 2016. In addition, a manual search was carried out in journals and with new keywords like temporomanbidular disorders, tetanus, traumas, genetic disorders and limited open mouth and coronoid process hiperplasia. Clinical studies, literature reviews, systematic reviews and case reports published in English or Portuguese were included in the review. Relevant aspects of temporomandibular joint disorders, tetanus, trauma and fractures, oral lesions, neoplasys and side effects of radiotherapy and chemotherapy, genetic disorders, and coronoid process hyperplasia were described. The diagnosis of oral opening limitation is complex because of the many causes of the problem. Therefore, it is very important that a correct anamnesis and detailed investigation of the patient's history be performed, in addition to performing complementary tests, thus allowing the cause of the problem to be detected and treated correctly, through a multidisciplinary approach, improving the quality of life and healing the patient(AU)

A fratura de côndilo mandibular é um dos tipos de traumas faciais mais comuns, podendo ser diagnosticado por diversos meios, sendo que uma variedade de planos de tratamentos podem ser instaurados. Este tipo de fratura configura também uma das etiologias da disfunção temporomandibular (DTM), portanto, é indispensável que o profissional realize exames minuciosos, inclusive por meio de exames complementares de imagem para o correto diagnóstico e conduta curativa, tanto da fratura, quanto da disfunção. Sendo assim, o objetivo deste estudo foi descrever um caso de fratura de côndilo mandibular não tratada seguida de DTM. Paciente de 36 anos do gênero masculino com histórico de acidente automobilístico há cinco anos, resultando em fratura de côndilo, com diagnóstico tardio e consolidação em posição inadequada buscou tratamento na Faculdade de Odontologia de Araçatuba - UNESP. A conduta por meio do uso de placa interoclusal levou à eliminação da sintomatologia dolorosa(AU)

The condylar fracture is one of the most common types of facial trauma and can be diagnosed by different methods, and a variety of treatment plans can be used. This type of fracture also constitutes one of the etiologies of temporomandibular disorders (TMD). Therefore, it is essential that the professional conduct thorough examinations, including complementary imaging tests for the correct diagnosis and treatment of the fracture and the dysfunction. Thus, the aim of this study was to describe a case of untreated condylar fracture followed by the development of TMD. A 36-year-old male patient with a history of automobile accident five years ago, resulting in condylar fracture, sought treatment at the Aracatuba Dental School - UNESP. The fracture had late diagnosis and consolidation in a wrong position. The conduct treatment through the use of occlusal splint led to the elimination of the painful symptomatology(AU)

OBJECTIVE: To compare electrical activity in the anterior temporal and masseter muscles on the habitual (HMS) and non-habitual mastication side (NHMS), during mastication and in the mandibular postural position. In addition, the increase in electrical activity during mastication was assessed for the HMS and NHMS, analysing both working (WSM) and non-working side during mastication (NWSM). METHODS: A total of 28 healthy women (18-32 years) participated in the study. They were submitted to Kazazoglu's test to identify the HMS. Bioresearch 'Bio EMG' software and bipolar surface electrodes were used in the exams. The exams were conducted in the postural position and during the unilateral mastication of raisins, on both the HMS and NHMS. The working and non-working side on HMS and NHMS were assessed separately. The obtained data were then statistically analysed with SPSS 20.0, using the Paired Samples Test at a significance level of 95%. RESULTS: The differences in the average EMG values between HMS and NHMS were not statistically significant in the postural position (Temporal p=0.2; Masseter p=0.4) or during mastication (Temporal WSM p=0.8; Temporal NWSM p=0.8; Masseter WSM p=0.6; Masseter NWSM p=0.2). Differences in the increase in electrical activity between the masseter and temporal muscles occurred on the working side, on the HMS and NHMS (p=0.0), but not on the non-working side: HMS (p=0.9) and NHMS (p=0.3). The increase in electrical activity was about 35% higher in the masseter than in the temporal muscle. CONCLUSIONS: Mastication side preference does not significantly impact electrical activity of the anterior temporal and masseter muscles during mastication or in postural position.

OBJECTIVE: The aim of this study was to evaluate the influence of oral contraceptive use on the silent period (SP) of anterior temporal and masseter muscles during the menstrual cycle. MATERIALS AND METHODS: Totally, 28 women on reproductive age were selected including 15 nonusers of any hormone and 13 contraceptive users. All patients were dentate without muscular temporomandibular disorders. Electromyography (SP test) of the anterior temporal and masseter muscles was conducted every week during three consecutive menstrual cycles at 1(st) day of menstruation (P1), 7(th) day (P2), 14(th) day (P3) and 21(st) day (P4). RESULTS: The SP values in the anterior temporal and masseter muscles were measured at both sides. The SP values of the right side (13.49 ms) at P2 were significantly different compared to the left side (12.28 ms). However, there was no significant difference on the interactions among the three factors. CONCLUSION: It can be concluded that the SP values in healthy women in reproductive age may not be influenced by the menstrual cycle with similar results for both muscles.

As alterações dimensionais das próteses podem comprometer a adaptação e retenção associadas à alteração oclusal, que são considerados fatores relevantes para a confecção de prótese total. Objetivo: O objetivo deste estudo foi o de avaliar o deslocamento linear dos dentes durante o processamento de próteses totais superiores submetidas a dois métodos de inclusão e polimerização convencional. Material e Métodos: Vinte próteses totais superiores foram fabricadas: G1- inclusão com barreira de silicone, e G2 inclusão com barreira de gesso tipo IV. Pontos foram marcados nas superfícies incisal do incisivo central direito e cúspides dos segundos molares para permitir as mensurações lineares das réplicas através do “sofware” Auto CAD. A avaliação dos deslocamentos dos dentes artificiais para ambos os grupos foi realizadas em diferentes momentos: a) dentadura encerada, b) dentadura encerada e parcialmente incluída com gesso ou silicone, c) após completa inclusão, d)dentadura incluída após a polimerização, e) dentadura aderida ao modelo após a demuflagem, f) dentadura separada do modelo, g) dentadura após o acabamento e polimento, h) após a permanência em água a 36º durante sete dias. Resultados: Ocorreram alterações lineares no posicionamento dos dentes artificiais para ambos os grupos e em todos os períodos da inclusão, com maior alteração para o grupo G2. Os dados das fases c e d foram significantemente diferentes das outras fases quando comparados intra grupos, para ambos os métodos de inclusão avaliados. Conclusão: O grupo G2 exibiu as maiores alterações. Após a polimerização, o grupo G1(inclusão com barreira de silicone complementada com gesso tipo III) demonstrou as maiores distâncias entre os pontos (expansão) enquanto o grupo G2 revelou as distâncias reduzidas (contração).

The dimensional alterations of denture base jeopardize adaptation and retention associated to altered occlusion, which are considered relevant factors forfabrication of complete dentures. Objective: The aimof this study was to evaluate linear tooth displacement during processing of maxillary complete dentures submitted to two inclusion methods and conventional polymerization. Material and Methods: Twenty maxillary complete dentures were fabricated: G1 –inclusion with silicone barrier, and G2 – inclusion with dental stone type IV barrier. Points were markedon incisal surface of right central incisor and cusp of second molars to allow linear measurement ofthe replicas through the software AutoCAD. The evaluation of artificial teeth displacement for both groups was carried out in different moments: a) waxed denture; b) waxed denture partially investedwith stone or silicone barrier; c) after complete flasking; d) denture into flask after polymerization;e) denture attached to the cast after deflasking; f)denture separated from the cast; g) denture after finishing and polishing; h) denture after storagein water at 36° during 7 days. Results: Linear alterations occurred on artificial teeth positioning for both groups and in all periods of inclusion, with higher alterations for group G2. The data from phasesc and d were significant different from other phases when compared intra groups, for both inclusion methods evaluated. Conclusion: Group G2 exhibited the greatest alterations. After polymerization, groupG1 (Inclusion with silicone barrier complementedwith dental stone type III) demonstrated higher distance between the points (expansion) while groupG2 revealed reduced distance (contraction).

Halitose é o odor desagradável do ar expelido pela cavidade oral, narinas ou faringe. Este odor origina-se principalmente pela presença de compostos sulfurados voláteis produzidos por bactérias presentes na cavidade oral. Pode ter origem fisiológica (estresse, hálito da manhã, jejum prolongado, dietas inadequadas); razões locais (má-higiene bucal, biofilme retido na língua e/ou amígdalas, baixa produção de saliva, gengivites e periodontites) ou mesmo razões sistêmicas (diabetes, problemas renais ou hepáticos, dentre outros). Na Terceira Idade, este problema tende a aumentar significativamente, devido a diversos fatores. Dessa forma, o objetivo deste estudo foi diagnosticar a presença de halitose no grupo geriátrico atendido na clínica odontológica da UNIRP, identificando sua incidência e principais causas. A amostra constituiu-se de 48 pacientes voluntários com 60 anos ou mais e abrangeu mais de 90% dos pacientes nessa faixa etária ali atendidos. Foram realizados uma anamnese e exame físico intra-oral e a halitose foi detectada utilizando um halímetro portátil. No grupo pesquisado, aproximadamente 54,16% apresentou halitose, destes 84,61% eram usuários de prótese. A saburra lingual esteve presente em 80,76% dos indivíduos com halitose. Após a escovação lingual, 88,46% dos portadores de halitose tiveram o índice inicialmente aferido pelo halímetro diminuído. Com base nos resultados deste estudo, concluiu-se que fatores como uso de próteses dentárias e presença de saburra lingual são determinantes etiológicos no surgimento da halitose

Halitosis is the unpleasant odor of exhaust air through the mouth and lungs. There are over 50 causes, and approximately 90% of cases, is of oral origin. May have physiological origin (stress, breath of morning, fasting, and inappropriate diets), local reasons (bad oral hygiene, bacterial plaque retained on the tongue and/or tonsils, lower production of saliva, gum disease) or systemic reasons (diabetes, kidney or liver problems, constipation, etc.). In the Third Age, this problem tends to increase significantly. Thus, the aim of this study was to detect the presence of halitosis in the geriatric group attended in the dental clinic of UNIRP, identifying their incidence and principal causes. The sample consisted of 48 volunteer patients aged 60 years or older and included more than 90% of patients treated in this age group. It was performed a anamnesis and physical examination. The intra-oral halitosis was detected using a breath meter (halimeter). In the group studied, approximately 54.16% had halitosis, 84.61% of these were users of the prosthesis. The tongue coating was present in 80.76% of individuals with halitosis. After brushing the tongue, 88.46% of patients with halitosis have had the initial index oral malodor decreased. Based on the results of this study it was concluded that factors as dental prostheses and tongue coating are critical factors in causing halitosis

This article describes an alternative two-step ocular prosthesis impression technique that employs two materials of different consistencies. The method is intended to provide better adaptation to underlying tissues, increased mobility of the prosthesis owing to improvements in facial contours, and improved esthetics, as well as offering the patient greater comfort and security. These advantages and this prosthesis' relative ease of fabrication mean it should be considered as the first step in the management of untreated anophthalmic sockets.

Temporomandibular joint (TMJ) sounds are frequent in patients. The aim of this study was to analyze patients with clicking at the end of opening and at the beginning of closing their mouths treated by muscular exercises through chewing and by occlusal splints. Fifteen patients with clinically verified clicking and TMJ and 15 patients without sounds were selected by the Research Diagnostic Criteria for Temporomandibular Disorders. They were submitted to electrovibratography at consultation and 60 and 120 days of treatment by occlusal splints and exercises. Patients demonstrated significant reduction of TMJ sounds after treatment, but vibration intensity was not similar with that of the control group after 120 days.

Os benzodiazepínicos respondem como uma das drogas mais prescritas e consumidas. O propósito deste trabalho foi estudar histologicamente o efeito de drogas benzodiazepínicas sobre o reparo ósseo. Cavidades ósseas foram criadas em ambas as tíbias de 40 ratos machos, divididos em dois grupos: controle e tratado. No grupo tratado, a droga foi administrada diariamente, na concentração de 5mg/Kg/peso corporal nos 15 dias pré-operatórios. Em grupos de cinco, os animais foram sacrificados aos 7,14,30 e 60 dias pós-operatórios. Aos 7 dias pós-operatórios a cavidade cirúrgica mostra-se preenchida por tecido conjuntivo denso, permeado por delicadas trabéculas ósseas neoformadas nos grupo controle e tratado. Aos 14 dias pós-operatórios as lojas cirúrgicas encontram-se totalmente preenchidas por tecido ósseo neoformado no grupo controle e parcialmente no grupo tratado. Aos 30 dias pós-operatórios a reparação óssea está completa e as lojas cirúrgicas encontram-se preenchidas por tecido ósseo secundário em ambos os grupos. Aos 60 dias pós-operatórios, tecido ósseo maduro e bem diferenciado ocupa todos os espécimes de ambos os grupos. Com base nos resultados obtidos conclui-se que o uso de drogas benzodiazepínicas não interferiu nos estádios de organização do coágulo de fibrina e ossificação da reparação óssea

Benzodiazepines respond as one of the most commonly prescribed drugs and consumed. The purpose of this study was to evaluate histologically the effect of benzodiazepine drugs on bone healing. Bone cavities were created in both tibias of 32 male rats were divided into two groups: control and treated. In the treated group, the drug was administered daily at a concentration of 5mg/Kg/peso body within 15 days of preoperative period. In groups of four animals were sacrificed at 7, 14, 30 and 60 days postoperatively. At 7 days postoperatively, while the control group showed connective tissue rich in fibroblasts, the treated group showed neoformed tissue with numerous fibroblasts and capillaries along with lymphocytes and macrophages. At 14 days postoperatively, the control group evolved into newly formed trabecular bone and the group treated for thin trabecular bone with numerous osteoblasts on their borders. At 30 days post-operative bone healing is complete surgical and shops are filled by secondary bone tissue in both groups. At 60 days post-surgery, bone tissue and well differentiated occupies all specimens of both groups. Based on the results it is concluded that the use of benzodiazepine drugs did not interfere in bone repair

Os hábitos parafuncionais, graças ao desencadeamento de alterações articulares e motoras, jogam importante papel no desenvolvimento das desordens temporomandibulares. Quando estas atividades excedem o nível de tolerância fisiológica do indivíduo são nocivos ao aparelho estomatognático. Neste estudo avaliou-se a influência do gênero na prevalência de 12 hábitos parafuncionais em acadêmicos da Faculdade de Odontologia de Araçatuba/Unesp no ano de 2009. O gênero feminino apresentou o dobro da prevalência para os hábitos parafuncionais (66,66%) em relação ao gênero masculino (33,34%). O hábito de mascar chicletes foi o mais prevalente, seguido de apoiar a mão no queixo, para ambos os gêneros. Orientação para controle e eliminação destes hábitos mostra-se necessária

The parafunctional habits, thanks to the onset of joint and motor, play important role in the development of temporomandibular disorders. When these activities beyond the level of physiological tolerance of the individual are harmful to the stomatognathic system. This study evaluated the influence of gender on prevalence of 12 parafunctional habits in students of the Faculty of Dentistry of Araçatuba/UNESP in 2009. Women have twice the prevalence of the parafunctional habits (66.66%) compared to males (33.34%). The habit of chewing gum was the most prevalent, followed by rest your hand on the chin, for both genders. Guidance for control and elimination of these habits proves necessary

The purpose of this study was to present a literature review about photoelasticity, a laboratory method for evaluation of implants prosthesis behavior. Fixed or removable prostheses function as levers on supporting teeth, allowing forces to cause tooth movement if not carefully planned. Hence, during treatment planning, the dentist must be aware of the biomechanics involved and prevent movement of supporting teeth, decreasing lever-type forces generated by these prosthesis. Photoelastic analysis has great applicability in restorative dentistry as it allows prediction and minimization of biomechanical critical points through modifications in treatment planning.

Várias são as causa de dor no ouvido, dentre elas, a dor miofascial do músculo masseter e/ou pterigóideo lateral. Este estudo procurou verificar o efeito do tratamento de pacientes com dor miofascial do músculo masseter, com algia referida para o ouvido, sobre as vibrações da articulação temporomandibular e atividade elétrica dos músculos masseter e temporal. Foram selecionados sete pacientes, os quais foram tratados com placa miorrelaxante, fisioterapia e analisados através de eletrovibratografia e eletromiografia. Notou-se diminuição nas vibrações presentes na articulação temporomandibular e na atividade elétrica, verificando-se, também, uma diminuição no período de silêncio dos músculos analisados. Os resultados permitiram concluir que o emprego de calor e a realização de exercícios musculares são eficazes no alívio da sintomatologia dolorosa

A terapia por placa oclusal tem muitas aplicações favoráveis que a torna extremamente útil no tratamento das desordens temporomandibulares. A etiologia destas desordens, na maioria das vezes, é multifatorial, por isto é muito importante que a terapia inicial seja reversível e não invasiva, o que valoriza ainda mais estes aparelhos como tratamento inicial. Diante disto o objetivo deste trabalho foi realizar um estudo piloto para analisar a sensibilidade dolorosa e limiar de dor antes e após placa interoclusal resiliente e rígida de pacientes jovens com apertamento dental e dor muscular. Para isto foram selecionados dez pacientes com dor tensional nos músculos masseter e temporal. Estes pacientes foram analisados por meio de palpação e algometria. Cinco deles foram tratados com placa interoclusal resiliente, e os outros cinco, com placa rígida. Foram novamente avaliados pós uma e duas semanas da instalação do aparelho. Os resultados foram submetidos à Análise de Variância a 5% de significância e demonstraram que não houve diferença estatisticamente significante entre as placas. A comparação dos momentos analisados (S1, S2, S3) mostrou que houve diferença significativa, sendo que todos os momentos foram diferentes entre si, tanto para a sensibilidade à palpação digital quanto para o limiar de dor. Pode-se concluir que no curto período avaliado ambas as placas mostraram resultados semelhantes, entretanto, estudo com amostra maior de pacientes e por um período mais prolongado deve ser realizado

Interocclusal appliances therapy has many favorable applications which turn it useful in temporomandibular disorders treatment. Etiology of these disorders is varied in the most of cases, and that’s why it is very important that the initial treatment be reversible and not invasive. It turns this kind of appliances very good as an initial choice of treatment. The aim of this study is do a pilot study to analyses pain before and after a resilient and rigid interocclusal appliance treatment. Ten patients with muscle pain were selected. They were analyzed by digital palpation and algometry, before and after one and two weeks of installation of appliances. Five of them were treated by soft interocclusal appliance and the other five with rigid one. The results were submitted toa variance analysis with 5% of significance e demonstrated that there was no difference between appliances. Comparison of moments demonstrated that they were different palpation and for pressure pain threshold. However, other research may be done in future
